Chapter 1. Technology Previews

1.1. Storage and File Systems
1.2. Networking
1.3. Clustering
1.4. Security
1.5. Devices
1.6. Kernel
1.7. Virtualization
Technology Preview features are currently not supported under Red Hat Enterprise Linux subscription services, may not be functionally complete, and are generally not suitable for production use. However, these features are included as a customer convenience and to provide the feature with wider exposure.
Customers may find these features useful in a non-production environment. Customers are also free to provide feedback and functionality suggestions for a Technology Preview feature before it becomes fully supported. Errata will be provided for high-severity security issues.
During the development of a Technology Preview feature, additional components may become available to the public for testing. It is the intention of Red Hat to fully support Technology Preview features in a future release.

1.1. Storage and File Systems

Parallel NFS
Parallel NFS (pNFS) is a part of the NFS v4.1 standard that allows clients to access storage devices directly and in parallel. The pNFS architecture eliminates the scalability and performance issues associated with NFS servers in deployment today.
pNFS supports 3 different storage protocols or layouts: files, objects and blocks. The Red Hat Enterprise Linux 6.2 NFS client supports the files layout protocol.
To automatically enable the pNFS functionality, create the /etc/modprobe.d/dist-nfsv41.conf file with the following line and reboot the system:
alias nfs-layouttype4-1 nfs_layout_nfsv41_files
Now when the -o minorversion=1 mount option is specified, and the server is pNFS-enabled, the pNFS client code is automatically enabled.
For more information on pNFS, refer to http://www.pnfs.com/.
Open multicast ping (Omping), BZ#657370
Open Multicast Ping (Omping) is a tool to test the IP multicast functionality, primarily in the local network. This utility allows users to test IP multicast functionality and assists in the diagnosing if an issues is in the network configuration or elsewhere (that is, a bug). In Red Hat Enterprise Linux 6 Omping is provided as a Technology Preview.
Matahari
Matahari provides a set of Application Programming Interfaces (APIs) for operating systems management for remote access over QMF/QPID. Matahari in Red Hat Enterprise Linux 6.2 is fully supported only for Intel 64 and AMD64 architectures. Builds for other architectures are considered a Technology Preview.
System Information Gatherer and Reporter (SIGAR)
The System Information Gatherer and Reporter (SIGAR) is a library and command-line tool for accessing operating system and hardware level information across multiple platforms and programming languages. In Red Hat Enterprise Linux 6.2, SIGAR is considered a Technology Preview package.
fsfreeze
Red Hat Enterprise Linux 6 includes fsfreeze as a Technology Preview. fsfreeze is a new command that halts access to a file system on a disk. fsfreeze is designed to be used with hardware RAID devices, assisting in the creation of volume snapshots. For more details on the fsfreeze utility, refer to the fsfreeze(8) man page.
DIF/DIX support
DIF/DIX, is a new addition to the SCSI Standard and a Technology Preview in Red Hat Enterprise Linux 6. DIF/DIX increases the size of the commonly used 512-byte disk block from 512 to 520 bytes, adding the Data Integrity Field (DIF). The DIF stores a checksum value for the data block that is calculated by the Host Bus Adapter (HBA) when a write occurs. The storage device then confirms the checksum on receive, and stores both the data and the checksum. Conversely, when a read occurs, the checksum can be checked by the storage device, and by the receiving HBA.
The DIF/DIX hardware checksum feature must only be used with applications that exclusively issue O_DIRECT I/O. These applications may use the raw block device, or the XFS file system in O_DIRECT mode. (XFS is the only file system that does not fall back to buffered I/O when doing certain allocation operations.) Only applications designed for use with O_DIRECT I/O and DIF/DIX hardware should enable this feature.
For more information, refer to section Block Devices with DIF/DIX Enabled in the Storage Administration Guide
File system in user space
Filesystem in Userspace (FUSE) allows for custom file systems to be developed and run in user space.
Btrfs, BZ#614121
Btrfs is under development as a file system capable of addressing and managing more files, larger files, and larger volumes than the ext2, ext3, and ext4 file systems. Btrfs is designed to make the file system tolerant of errors, and to facilitate the detection and repair of errors when they occur. It uses checksums to ensure the validity of data and metadata, and maintains snapshots of the file system that can be used for backup or repair. The btrfs Technology Preview is only available on AMD64 and Intel 64 architectures.

Btrfs is still experimental

Red Hat Enterprise Linux 6 includes Btrfs as a technology preview to allow you to experiment with this file system. You should not choose Btrfs for partitions that will contain valuable data or that are essential for the operation of important systems.
LVM Application Programming Interface (API)
Red Hat Enterprise Linux 6 features the new LVM application programming interface (API) as a Technology Preview. This API is used to query and control certain aspects of LVM.
LVM RAID support, BZ#729712
In Red Hat Enterprise Linux 6.2, support for MD's RAID personalities has been added to LVM as a Technology Preview. The following basic features are available: create, display, rename, use, and remove RAID logical volumes. Automated fault tolerance is not yet available.
FS-Cache
FS-Cache is a new feature in Red Hat Enterprise Linux 6 that enables networked file systems (e.g. NFS) to have a persistent cache of data on the client machine.

1.2. Networking

vios-proxy, BZ#721119
vios-proxy is a stream-socket proxy for providing connectivity between a client on a virtual guest and a server on a Hypervisor host. Communication occurs over virtio-serial links.
IPv6 support in IPVS
The IPv6 support in IPVS (IP Virtual server) is considered a Technology Preview.

1.3. Clustering

Support for redundant ring for standalone Corosync, BZ#722469
Red Hat Enterprise Linux 6.2 introduces support for redundant ring with autorecovery feature as a Technology Preview. Refer to Section 2.7, “Clustering” for a list of known issues associated with this Technology Preview.
corosync-cpgtool, BZ#688260
The corosync-cpgtool now specifies both interfaces in a dual ring configuration. This feature is a Technology Preview.
Disabling rgmanager in /etc/cluster.conf, BZ#723925
As a consequence of converting the /etc/cluster.conf configuration file to be used by pacemaker, rgmanager must be disabled. The risk of not doing this is high; after a successful conversion, it would be possible to start rgmanager and pacemaker on the same host, managing the same resources.
Consequently, Red Hat Enterprise Linux 6.2 includes a feature (as a Technology Preview) that forces the following requirements:
  • rgmanager must refuse to start if it sees the <rm disabled="1"> flag in /etc/cluster.conf.
  • rgmanager must stop any resources and exit if the <rm disabled="1"> flag appears in /etc/cluster.conf during a reconfiguration.
pacemaker, BZ#456895
Pacemaker, a scalable high-availability cluster resource manager, is included in Red Hat Enterprise Linux 6 as a Technology Preview. Pacemaker is not fully integrated with the Red Hat cluster stack.
XFS in the Red Hat Enterprise Linux 6 High Availability Add On, BZ#661888
The XFS file system failover in the Red Hat Enterprise Linux 6 High Availability Add-On is considered a Technology Preview. Note that XFS and the Scalable File System Add-On are fully-supported in Red Hat Enterprise Linux 6.

1.4. Security

Trusted boot
Red Hat Enterprise Linux 6.2 includes a trusted boot mechanism (provided by the tboot package) as Technology Preview. Trusted boot is an install-time optional component that allows for Intel's Trusted Execution Technology (TXT) to perform a measured and verified launch of the operating system kernel. Trusted boot is supported on 32-bit Intel x86, and 64-bit Intel EM64T and AMD64 architectures.
TPM
TPM hardware can create, store and use RSA keys securely (without ever being exposed in memory), verify a platform's software state using cryptographic hashes and more. The user space libraries, trousers and tpm-tools, are considered a Technology Preview.

1.5. Devices

Brocade BFA driver
The Brocade BFA driver is considered a Technology Preview feature in Red Hat Enterprise Linux 6. The BFA driver supports Brocade FibreChannel and FCoE mass storage adapters.
SR-IOV on the be2net driver, BZ#602451
The SR-IOV functionality of the Emulex be2net driver is considered a Technology Preview in Red Hat Enterprise Linux 6.

1.6. Kernel

Support for Fiber Channel over Ethernet (FCoE) target mode
Red Hat Enterprise Linux 6.2 includes support for Fiber Channel over Ethernet (FCoE) target mode as a Technology Preview. This kernel feature is configurable via targetadmin, supplied by the fcoe-target-utils package. FCoE is designed to be used on a network supporting Data Center Bridging (DCB). Further details are available in the dcbtool(8) and targetadmin(8) man pages.

Important

This feature uses the new SCSI target layer, which falls under this Technology Preview, and should not be used independently from the FCoE target support. This package contains the AGPL license.
Kernel Media support
The following features are presented as Technology Previews:
  • The latest upstream video4linux
  • Digital video broadcasting
  • Primarily infrared remote control device support
  • Various webcam support fixes and improvements
Remote audit logging
The audit package contains the user space utilities for storing and searching the audit records generated by the audit subsystem in the Linux 2.6 kernel. Within the audispd-plugins subpackage is a utility that allows for the transmission of audit events to a remote aggregating machine. This remote audit logging application, audisp-remote, is considered a Technology Preview in Red Hat Enterprise Linux 6.
Linux (NameSpace) Container [LXC]
Linux containers provide a flexible approach to application runtime containment on bare-metal systems without the need to fully virtualize the workload. Red Hat Enterprise Linux 6.2 provides application level containers to separate and control the application resource usage policies via cgroup and namespaces. This release introduces basic management of container life-cycle by allowing creation, editing and deletion of containers via the libvirt API and the virt-manager GUI. Linux Containers are a Technology Preview.
Error Detection And Correction (EDAC) driver interface
The Error Detection And Correction (EDAC) driver interface for processors based on the Intel microarchitecture codename Nehalem is considered a Technology Preview in this release of Red Hat Enterprise Linux 6.
Diagnostic pulse for the fence_ipmilan agent, BZ#655764
A diagnostic pulse can now be issued on the IPMI interface using the fence_ipmilan agent. This new Technology Preview is used to force a kernel dump of a host if the host is configured to do so. Note that this feature is not a substitute for the off operation in a production cluster.
EDAC driver support, BZ#647700
Red Hat Enterprise Linux 6.2's EDAC driver support for the latest Intel chipset is available as a Technical Preview.

1.7. Virtualization

System monitoring via SNMP, BZ#642556
This feature provides KVM support for stable technology that is already used in data center with bare metal systems. SNMP is the standard for monitoring and is extremely well understood as well as computationally efficient. System monitoring via SNMP in Red Hat Enterprise Linux 6.2 allows the KVM hosts to send SNMP traps on events so that hypervisor events can be communicated to the user via standard SNMP protocol. This feature is provided through the addition of a new package: libvirt-snmp. This feature is introduced as a Technology Preview.
Wire speed requirement in KVM network drivers
Virtualization and cloud products that run networking work loads need to run wire speeds. Up until Red Hat Enterprise Linux 6.1, the only way to reach wire speed on a 10 GB Ethernet NIC with a lower CPU utilization was to use PCI device assignment (passthrough), which limits other features like memory overcommit and guest migration
The macvtap/vhost zero-copy capabilities allows the user to use those features when high performance is required. This feature improves performance for any Red Hat Enterprise Linux 6.x guest in the VEPA use case. This feature is introduced as a Technology Preview.
KVM Live Snapshots
Red Hat Enterprise Linux 6.2 introduces the Live Snapshot feature as a Technology Preview. The live snapshots feature provides automatic backup of virtual machine images on the hard drive, and provides a per drive snapshot of the virtual disks transparently, using external qcow2 images. Multi-disk live snapshot creation helps with maintaining data integrity by pausing qemu prior to taking as many snapshots as there are disks. Thus, a multi-disk snapshot will have all disks containing data from the same point in time.
It is important to know that there is a limitation with file system consistency. However, the re-use of the snapshot image is crash-consistent. A user would have to run a file system check (fsck) or replay journal entries, which is similar to booting after pulling the power cord.

2.1. Installation

anaconda component, BZ#676025
Users performing an upgrade using the Anaconda's text mode interface who do not have a boot loader already installed on the system, or who have a non-GRUB boot loader, need to select Skip Boot Loader Configuration during the installation process. Boot loader configuration will need to be completed manually after installation. This problem does not affect users running Anaconda in the graphical mode (graphical mode also includes VNC connectivity mode).
anaconda component
Anaconda fails to install to partitions of size 2.2 TB and larger.
anaconda component
On s390x systems, you cannot use automatic partitioning and encryption. If you want to use storage encryption, you must perform custom partitioning. Do not place the /boot volume on an encrypted volume.
anaconda component
The order of device names assigned to USB attached storage devices is not guaranteed. Certain USB attached storage devices may take longer to initialize than others, which can result in the device receiving a different name than you expect (for example, sdc instead of sda).
During installation, verify the storage device size, name, and type when configuring partitions and file systems.
kernel component
Dell systems based on a future Intel processor with graphics acceleration require the selection of the install system with basic video driver installation option. A future Red Hat Enterprise Linux 6.2.z Extended Update Support update will remove this requirement.
kernel component
Recent Red Hat Enterprise Linux 6 releases use a new naming scheme for network interfaces on some machines. As a result, the installer may use different names during an upgrade in certain scenarios (typically em1 is used instead of eth0 on new Dell machines). However, the previously used network interface names are preserved on the system and the upgraded system will still use the previously used interfaces. This is not the case for Yum upgrades.
anaconda component
The kdump default on feature currently depends on Anaconda to insert the crashkernel= parameter to the kernel parameter list in the boot loader's configuration file.
firstaidkit component
The firstaidkit-plugin-grub package has been removed from Red Hat Enterprise Linux 6.2. As a consequence, in rare cases, the system upgrade operation may fail with unresolved dependencies if the plug-in has been installed in a previous version of Red Hat Enterprise Linux. To avoid this problem, the firstaidkit-plugin-grub package should be removed before upgrading the system. However, in most cases, the system upgrade completes as expected.
anaconda component, BZ#623261
In some circumstances, disks that contain a whole disk format (for example, a LVM Physical Volume populating a whole disk) are not cleared correctly using the clearpart --initlabel kickstart command. Adding the --all switch—as in clearpart --initlabel --all—ensures disks are cleared correctly.
squashfs-tools component
During the installation on POWER systems, error messages similar to:
attempt to access beyond end of device
loop0: rw=0, want=248626, limit=248624
may be returned to sys.log. These errors do not prevent installation and only occur during the initial setup. The file system created by the installer will function correctly.
anaconda component
When installing on the IBM System z architecture, if the installation is being performed over SSH, avoid resizing the terminal window containing the SSH session. If the terminal window is resized during the installation, the installer will exit and the installation will terminate.
yaboot component, BZ#613929
The kernel image provided on the CD/DVD is too large for Open Firmware. Consequently, on the POWER architecture, directly booting the kernel image over a network from the CD/DVD is not possible. Instead, use yaboot to boot from a network.
anaconda component
The Anaconda partition editing interface includes a button labeled Resize. This feature is intended for users wishing to shrink an existing file system and an underlying volume to make room for an installation of a new system. Users performing manual partitioning cannot use the Resize button to change sizes of partitions as they create them. If you determine a partition needs to be larger than you initially created it, you must delete the first one in the partitioning editor and create a new one with the larger size.
system-config-kickstart component
Channel IDs (read, write, data) for network devices are required for defining and configuring network devices on IBM S/390 systems. However, system-config-kickstart—the graphical user interface for generating a kickstart configuration—cannot define channel IDs for a network device. To work around this issue, manually edit the kickstart configuration that system-config-kickstart generates to include the desired network devices.
dracut component
During FCoE BFS installation, when an Ethernet interface goes offline after discovering the targets, FCoE link will never come up. This is because Anaconda creates an FCoE configuration file under/etc/fcoe/ using biosdevname (new style interface naming scheme) for all the available Ethernet interfaces for FCoE BFS. However, it does not add the ifname kernel command line for the FCoE interface that stays offline after discovering FCoE targets during installation. Because of this, during subsequent reboots, the system tries to find the old style ethX interface name in the /etc/fcoe directory, which does not match with the file created by Anaconda using biosdevname. Therefore, due to the missing FCoE configuration file, an FCoE interface is never created on the Ethernet interface.
To avoid this problem, ensure that the Ethernet interface does not go offline during FCoE BFS installation.
If the Ethernet interface does go offline during installation after discovering the targets, add the following parameter to the kernel command line:
ifname=<biosdevname_interface_name>:<mac_address>

2.2. Entitlement

subscription manager component
When registering a system with firstboot, the RHN Classic option is checked by default in the Subscription part.

2.3. Deployment

cpuspeed component, BZ#626893
Some HP Proliant servers may report incorrect CPU frequency values in /proc/cpuinfo or /sys/device/system/cpu/*/cpufreq. This is due to the firmware manipulating the CPU frequency without providing any notification to the operating system. To avoid this ensure that the HP Power Regulator option in the BIOS is set to OS Control. An alternative available on more recent systems is to set Collaborative Power Control to Enabled.
releng component, BZ#644778
Some packages in the Optional repositories on RHN have multilib file conflicts. Consequently, these packages cannot have both the primary architecture (for example, x86_64) and secondary architecture (for example, i686) copies of the package installed on the same machine simultaneously. To work around this issue, install only one copy of the conflicting package.
releng component
The openmpi-psm and openmpi-psm-devel packages are not provided on architectures other than AMD64 and Intel 64 for Red Hat Enterprise Linux 6.2. If the openmpi-psm.i686 or/and openmpi-psm-devel.i686 packages are installed on a AMD64 or an Intel 64 system, remove these packages before you attempt to update Open MPI.
grub component, BZ#695951
On certain UEFI-based systems, you may need to type BOOTX64 rather than bootx64 to boot the installer due to case sensitivity issues.
grub component, BZ#698708
When rebuilding the grub package on the x86_64 architecture, the glibc-static.i686 package must be used. Using the glibc-static.x86_64 package will not meet the build requirements.
parted component
The parted utility in Red Hat Enterprise Linux 6 cannot handle Extended Address Volumes (EAV) Direct Access Storage Devices (DASD) that have more than 65535 cylinders. Consequently, EAV DASD drives cannot be partitioned using parted, and installation on EAV DASD drives will fail. To work around this issue, complete the installation on a non EAV DASD drive, then add the EAV device after the installation using the tools provided in the s390-utils package.
PackageKit component
If you are being asked repeatedly to enter your root password while using PackageKit to update your system via non-Red Hat repositories, you may be affected by the PackageKit issue described in Section 2.11, “Desktop”.

2.4. Virtualization

ovirt-node component, BZ#747102
Upgrades from Beta to the GA version will result in an incorrect partitioning of the host. The GA version must be installed clean. UEFI machines must be set to legacy boot options for RHEV-H to boot successfully after installation.
kernel component
When a system boots from SAN, it starts the libvirtd service, which enables IP forwarding. The service causes a driver reset on both Ethernet ports which causes a loss of all paths to an OS disk. Under this condition, the system cannot load firmware files from the OS disk to initialize Ethernet ports, eventually never recovers paths to the OS disk, and fails to boot from SAN. To work around this issue add the bnx2x.disable_tpa=1 option to the kernel command line of the GRUB menu, or do not install virtualization related software and manually enable IP forwarding when needed.
kernel component
Booting Red Hat Enterprise Linux 6.2 as an HVM guest with more than one vCPU on machines that support SMEP and using Red Hat Enterprise Linux 5.7 and earlier Xen Hypervisors fails. To work around this issue, boot the guest with the nosmep kernel command line option.
vdsm component
If the /root/.ssh directory is missing from a host when it is added to a Red Hat Enterprise Virtualization Manager data center, the directory is created with a wrong SELinux context, and SSH'ing into the host is denied. To work around this issue, manually create the /root/.ssh directory with the correct SELinux context:
~]# mkdir /root/.ssh
~]# chmod 0700 /root/.ssh
~]# restorecon /root/.ssh
vdsm component
VDSM now configures libvirt so that connection to its local read-write UNIX domain socket is password-protected by SASL. The intention is to protect virtual machines from human errors of local host administrators. All operations that may change the state of virtual machines on a Red Hat Enterprise Virtualization-controlled host must be performed from Red Hat Enterprise Virtualization Manager.
libvirt component
In earlier versions of Red Hat Enterprise Linux, libvirt permitted PCI devices to be insecurely assigned to guests. In Red Hat Enterprise Linux 6, assignment of insecure devices is disabled by default by libvirt. However, this may cause assignment of previously working devices to start failing. To enable the old, insecure setting, edit the /etc/libvirt/qemu.conf file, set the relaxed_acs_check = 1 parameter, and restart libvirtd (service libvirtd restart). Note that this action will re-open possible security issues.
virtio-win component, BZ#615928
The balloon service on Windows 7 guests can only be started by the Administrator user.
libvirt component, BZ#622649
libvirt uses transient iptables rules for managing NAT or bridging to virtual machine guests. Any external command that reloads the iptables state (such as running system-config-firewall) will overwrite the entries needed by libvirt. Consequently, after running any command or tool that changes the state of iptables, guests may lose access the network. To work around this issue, use the service libvirt reload command to restore libvirt's additional iptables rules.
virtio-win component, BZ#612801
A Windows virtual machine must be restarted after the installation of the kernel Windows driver framework. If the virtual machine is not restarted, it may crash when a memory balloon operation is performed.
qemu-kvm component, BZ#720597
Installation of Windows 7 Ultimate x86 (32-bit) Service Pack 1 on a guest with more than 4GB of RAM and more than one CPU from a DVD medium often crashes during the final steps of the installation process due to a system hang. To work around this issue, use the Windows Update utility to install the Service Pack.
qemu-kvm component, BZ#612788
A dual function Intel 82576 Gigabit Ethernet Controller interface (codename: Kawela, PCI Vendor/Device ID: 8086:10c9) cannot have both physical functions (PF's) device-assigned to a Windows 2008 guest. Either physical function can be device assigned to a Windows 2008 guest (PCI function 0 or function 1), but not both.
virt-v2v component
In Red Hat Enterprise Linux 6.2, the default virt-v2v configuration is split into two files: /etc/virt-v2v.conf and /var/lib/virt-v2v/virt-v2v.db. The former now contains only local customizations, whereas the latter contains generic configuration which is not intended to be customized. Prior to Red Hat Enterprise Linux 6.2, virt-v2v's -f flag defaulted to /etc/virt-v2v.conf. In Red Hat Enterprise Linux 6.2, it now defaults to both /etc/virt-v2v.conf and /var/lib/virt-v2v/virt-v2v.db. Data from both of these files is required during conversion.
This change has no impact for most users. If a machine is upgraded from Red Hat Enterprise Linux 6.1 to Red Hat Enterprise Linux 6.2, the existing combined /etc/virt-v2v.conf will not be updated. If a user explicitly specifies -f /etc/virt-v2v.conf on the command line, the behavior will be identical to the one prior to update. If the user does not specify the -f command line option, the configuration will use both /etc/virt-v2v.conf and /var/lib/virt-v2v/virt-v2v.db, with the former taking precedence.
However, a freshly-installed Red Hat Enterprise Linux 6.2 machine with a default configuration no longer has all required data in /etc/virt-v2v.conf. If the user explicitly specifies -f /etc/virt-v2v.conf on the command line, virt-v2v will not be able to enable virtio support for any guests.
To work around this issue, do use the -f command line option, as this defaults to using both configuration files. If the -f command line option is used, it must be specified twice: first for /etc/virt-v2v.conf and second for /var/lib/virt-v2v/virt-v2v.conf.
If the virt-v2v command line cannot be altered, the /etc/virt-v2v.conf file must contain a combined configuration file. This can be copied from a Red Hat Enterprise Linux 6.1 system, or created by copying all configuration elements from /var/lib/virt-v2v/virt-v2v.db to /etc/virt-v2v.conf.
virt-v2v component, BZ#618091
The virt-v2v utility is able to convert guests running on an ESX server. However, if an ESX guest has a disk with a snapshot, the snapshot must be on the same datastore as the underlying disk storage. If the snapshot and the underlying storage are on different datastores, virt-v2v will report a 404 error while trying to retrieve the storage.
virt-v2v component, BZ#678232
The VMware Tools application on Microsoft Windows is unable to disable itself when it detects that it is no longer running on a VMware platform. Consequently, converting a Microsoft Windows guest from VMware ESX, which has VMware Tools installed, will result in errors. These errors usually manifest as error messages on start-up, and a "Stop Error" (also known as a BSOD) when shutting down the guest. To work around this issue, uninstall VMware Tools on Microsoft Windows guests prior to conversion.
spice-client component
Sound recording only works when there is no application accessing the recording device at the client start-up.

2.5. Storage and File Systems

device-mapper-multipath component
Multipath's queue_without_daemon yes default option queues I/O even though all iSCSI links have been disconnected when the system is shut down, which causes LVM to become unresponsive when scanning all block devices. As a result, the system cannot be shut down. To work around this issue, add the following line into the defaults section of /etc/multipath.conf:
queue_without_daemon no
initscripts component
Running the file system check (using fsck) on a NFS mounted file system fails, and causes the system to fail to boot and drop into a shell. To work around this issue, disable fsck on any /boot partitions by setting the sixth value of a /boot entry in /etc/fstab to 0.
iscsi-initiator-utils component, BZ#739843
iSCSI discovery via a TOE (TCP Offload Engine) interface fails when the iscsiadm -m iface has never been executed. This is due to the iscsiadm -m discovery command not checking interface settings while the iscsiadm -m iface does. To work around this issue, run the iscsiadm -m iface command at least once after installing the iscsi-initiatio-utils package. Once the interface setting is updated, discoveries are performed with no errors.
vdsm component
Attempting to create/extend a storage domain on/with a device that exposes a block size different than 512 bytes such create/extend request to fail. To work around this issue, the storage must be configured to expose a block size of 512 bytes.
kernel component, BZ#606260
The NFSv4 server in Red Hat Enterprise Linux 6 currently allows clients to mount using UDP and advertises NFSv4 over UDP with rpcbind. However, this configuration is not supported by Red Hat and violates the RFC 3530 standard.
lvm2 component
The dracut utility currently only supports one FiberChannel over Ethernet (FCoE) connection to be used to boot from the root device. Consequently, booting from a root device that spans multiple FCoE devices (for example, using RAID, LVM or similar techniques) is not possible.
lvm2 component
The pvmove command cannot currently be used to move mirror devices. However, it is possible to move mirror devices by issuing a sequence of two commands. For mirror images, add a new image on the destination PV and then remove the mirror image on the source PV:
~]$ lvconvert -m +1 <vg/lv> <new PV>
~]$ lvconvert -m -1 <vg/lv> <old PV>
Mirror logs can be handled in a similar fashion:
~]$ lvconvert --mirrorlog core <vg/lv>
~]$ lvconvert --mirrorlog disk <vg/lv> <new PV>
or
~]$ lvconvert --mirrorlog mirrored <vg/lv> <new PV>
~]$ lvconvert --mirrorlog disk <vg/lv> <old PV>
lvm2 component
Hyphens cannot be used as a part of an LVM volume group name or a logical volume name. Additionally, each name must be less than 64 characters in length, ensuring that the total length of the volume group name plus the logical volume name does not exceed 126 characters in length.

2.6. Networking

NetworkManager component
To ensure that RFC3442-standard classless static routes provided by a DHCP server are processed correctly when using NetworkManager, the following lines should be placed into the /etc/dhclient.conf file or, if using per-interface DHCP options, the /etc/dhclient-<ifname>.conf file:
option rfc3442-classless-static-routes code 121 = array of unsigned integer 8;
option ms-classless-static-routes code 249 = array of unsigned integer 8;
also request rfc3442-classless-static-routes;
also request ms-classless-static-routes;
The above lines will ensure that RFC3442 classless static routes are requested from the DHCP server, and that they are properly processed by NetworkManager.
iprutils component
Users of the IBM PCI-E Gen2 6GB SAS RADI adapter (FC 5913) in Red Hat Enterprise Linux 6.2 may encounter the following issues:
  • Updating firmware on a storage drawer that is connected to the adapter mentioned above using the iprconfig command fails.
  • Attempting to change the asymmetric access for an array results in a failure. Additionally, not specifying asymmetric access as an option to the iprconfig command results in a failure as well.

2.7. Clustering

corosync component, BZ#722469
A double ring failure results in the spinning of the corosync process. Also, because DLM relies on SCTP, which is non-functional, many features of the cluster software that rely on DLM do not work properly.
luci component, BZ#615898
luci will not function with Red Hat Enterprise Linux 5 clusters unless each cluster node has ricci version 0.12.2-14

2.8. Authentication

Identity Management component
When transitioning to a fully supported Identity Management version in Red Hat Enterprise Linux 6.2, uninstall any previous beta version of Identity Management or Technology Preview parts of Red Hat Enterprise Identity (IPA) available in the Red Hat Enterprise Linux 6.1 Technology Preview and install Identity Management again.
Identity Management component
When an Identity Management server is installed with a custom hostname that is not resolvable, the ipa-server-install command should add a record to the static hostname lookup table in /etc/hosts and enable further configuration of Identity Management integrated services. However, a record is not added to /etc/hosts when an IP address is passed as an CLI option and not interactively. Consequently, Identity Management installation fails because integrated services that are being configured expect the Identity Management server hostname to be resolvable. To work around this issue, complete one of the following:
  • Run the ipa-server-install without the --ip-address option and pass the IP address interactively.
  • Add a record to /etc/hosts before the installation is started. The record should contain the Identity Management server IP address and its full hostname (the hosts(5) man page specifies the record format).
As a result, the Identity Management server can be installed with a custom hostname that is not resolvable.
sssd component, BZ#750922
Upgrading SSSD from the version provided in Red Hat Enterprise Linux 6.1 to the version shipped with Red Hat Enterprise Linux 6.2 may fail due to a bug in the dependent library libldb. This failure occurs when the SSSD cache contains internal entries whose distinguished name contains the \, character sequence. The most likely example of this is for an invalid memberUID entry to appear in an LDAP group of the form:
memberUID: user1,user2
memberUID is a multi-valued attribute and should not have multiple users in the same attribute.
If the upgrade issue occurs, identifiable by the following debug log message:
(Wed Nov  2 15:18:21 2011) [sssd] [ldb] (0): A transaction is still active in
ldb context [0xaa0460] on /var/lib/sss/db/cache_<DOMAIN>.ldb
remove the /var/lib/sss/db/cache_<DOMAIN>.ldb file and restart SSSD.

Removing the /var/lib/sss/db/cache_<DOMAIN>.ldb file

Removing the /var/lib/sss/db/cache_<DOMAIN>.ldb file purges the cache of all entries (including cached credentials).
sssd component, BZ#751314
When a group contains certain incorrect multi-valued memberUID values, SSSD fails to sanitize the values properly. The memberUID value should only contain one username. As a result, SSSD creates incorrect users, using the broken memberUID values as their usernames. This, for example, causes problems during cache indexing.
Identity Management component, BZ#750596
Two Identity Management servers, both with a CA (Certificate Authority) installed, use two replication replication agreements. One is for user, group, host, and other related data. Another replication agreement is established between the CA instances installed on the servers. If the CA replication agreement is broken, the Identity Management data is still shared between the two servers, however, because there is no replication agreement between the two CAs, issuing a certificate on one server will cause the other server to not recognize that certificate, and vice versa.
Identity Management component
The Identity Management (ipa) package cannot be build with a 6ComputeNode subscription.
Identity Management component
On the configuration page of the Identity Management WebUI, if the User search field is left blank, and the search button is clicked, an internal error is returned.
sssd component, BZ#741264
Active Directory performs certain LDAP referral-chasing that is incompatible with the referral mechanism included in the openldap libraries. Notably, Active Directory sometimes attempts to return a referral on an LDAP bind attempt, which used to cause a hang, and is now denied by the openldap libraries. As a result, SSSD may suffer from performance issues and occasional failures resulting in missing information.
To work around this issue, disable referral-chasing by setting the following parameter in the [domain/DOMAINNAME] section of the /etc/sssd/sssd.conf file:
ldap_referrals = false

2.9. Devices

kernel component
iSCSI and FCoE boot support on Broadcom devices is not included in Red Hat Enterprise Linux 6.2. These two new features, which have been added to the bnx2i and bnx2fc Broadcom drivers in Red Hat Enterprise Linux 6.2, remain a Technology Preview until further notice.
kexec-tools component
Starting with Red Hat Enterprise Linux 6.0 and later, kexec kdump supports dumping core to the Brtfs file system. However, note that because the findfs utility in busybox does not support Btrfs yet, UUID/LABEL resolving is not functional. Avoid using the UUID/LABEL syntax when dumping core to Btrfs file systems.
kexec-tools component, BZ#600575
The persistent naming of devices that are dynamically discovered in a system is a large problem that exists both in and outside of kdump. Normally, devices are detected in the same order, which leads to consistent naming. In cases where devices are not detected in the same order, device abstraction layers (for example, LVM) essentially resolve the issue, through the use of metadata stored on the devices to create consistency. In the rare cases where no such abstraction layer is in use, and renaming devices causes issues with kdump, it is recommended that devices be referred to by disk label or UUID in kdump.conf.
trace-cmd component
The trace-cmd service does start on 64-bit PowerPC and IBM System z systems because the sys_enter and sys_exit events do not get enabled on the aforementioned systems.
trace-cmd component
trace-cmd's subcommand, report, does not work on IBM System z systems. This is due to the fact that the CONFIG_FTRACE_SYSCALLS parameter is not set on IBM System z systems.
tuned component
Red Hat Enterprise Linux 6.1 and later enter processor power-saving states more aggressively. This may result in a small performance penalty on certain workloads. This functionality may be disabled at boot time by passing the intel_idle.max_cstate=0 parameter, or at run time by using the cpu_dma_latency pm_qos interface.
libfprint component
Red Hat Enterprise Linux 6 only has support for the first revision of the UPEK Touchstrip fingerprint reader (USB ID 147e:2016). Attempting to use a second revision device may cause the fingerprint reader daemon to crash. The following command returns the version of the device being used in an individual machine:
~]$ lsusb -v -d 147e:2016 | grep bcdDevice
kernel component
The Emulex Fibre Channel/Fibre Channel-over-Ethernet (FCoE) driver in Red Hat Enterprise Linux 6 does not support DH-CHAP authentication. DH-CHAP authentication provides secure access between hosts and mass storage in Fibre-Channel and FCoE SANs in compliance with the FC-SP specification. Note, however that the Emulex driver (lpfc) does support DH-CHAP authentication on Red Hat Enterprise Linux 5, from version 5.4. Future Red Hat Enterprise Linux 6 releases may include DH-CHAP authentication.
kernel component
The recommended minimum HBA firmware revision for use with the mpt2sas driver is "Phase 5 firmware" (that is, with version number in the form 05.xx.xx.xx). Note that following this recommendation is especially important on complex SAS configurations involving multiple SAS expanders.

2.10. Kernel

kernel component
When booted off a qla4xxx device, upgrading from Red Hat Enterprise Linux 6.1 to Red Hat Enterprise Linux 6.2 will cause the system to fail to boot up with the new kernel. There are various ways to work around this issue:
  1. You have upgraded to Red Hat Enterprise Linux 6.2 and want the qla4xxx device firmware to manage discovering and logging in to iSCSI targets.
    1. Boot up the system with the Red Hat Enterprise Linux 6.1 kernel.
    2. Disable SysfsBoot for the qla4xxx device:
      ~]# echo "options qla4xxx ql4xdisablesysfsboot=1" >> /etc/modprobe.d/qla4xxx.conf
    3. Rebuild initramfs for the Red Hat Enterprise Linux 6.2 kernel by re-installing the kernel:
      ~]# yum -y reinstall kernel
  2. You have not upgraded to Red Hat Enterprise Linux 6.2 and want the qla4xxx device firmware to manage discovering and logging in to iSCSI targets.
    1. Boot up the system with the Red Hat Enterprise Linux 6.1 kernel.
    2. Disable SysfsBoot for the qla4xxx device:
      ~]# echo "options qla4xxx ql4xdisablesysfsboot=1" >> /etc/modprobe.d/qla4xxx.conf
    3. Proceed with the upgrade to Red Hat Enterprise Linux 6.2.
  3. You have upgraded to Red Hat Enterprise Linux 6.2 and want to use open-iscsi to manage the qla4xxx discovery and login process.
    1. Boot up the system with the Red Hat Enterprise Linux 6.1 kernel.
    2. Install the iscsi-initiator-utils and dracut-network packages:
      ~]# yum install -y dracut-network iscsi-initiator-utils
    3. Rebuild initramfs for the Red Hat Enterprise Linux 6.2 kernel by re-installing the kernel:
      ~]# yum -y reinstall kernel
    4. Add the iscsi_firmware kernel option into GRUB's configuration: /boot/grub/menu.lst (for LILO, the Linux Loader, modify the /etc/lilo.conf file).
  4. You have not upgraded to Red Hat Enterprise Linux 6.2 and want to use open-iscsi to manage the qla4xxx discovery and login process.
    1. Install the iscsi-initiator-utils and dracut-network packages:
      ~]# yum install -y dracut-network iscsi-initiator-utils
    2. Proceed with the upgrade to Red Hat Enterprise Linux 6.2.
    3. Add the iscsi_firmware kernel option into GRUB's configuration: /boot/grub/menu.lst (for LILO, the Linux Loader, modify the /etc/lilo.conf file).

Red Hat Enterprise Linux 6.1 PCI-Express Adapters may fail to configure on October 2011 GA IBM Power 7 systems. For more information, refer to https://access.redhat.com/kb/docs/DOC-66231.
kernel component
Superfluous information is displayed on the console due to a correctable machine check error occurring. This information can be safely ignored by the user. Machine check error reporting can be disabled by using the nomce kernel boot option, which disables machine check error reporting, or the mce=ignore_ce kernel boot option, which disables correctable machine check error reporting.
kernel component
The order in which PCI devices are scanned may change from one major Red Hat Enterprise Linux release to another. This may result in device names changing, for example, when upgrading from Red Hat Enterprise Linux 5 to 6. You must confirm that a device you refer to during installation, is the intended device.
One way to assure the correctness of device names is to, in some configurations, determine the mapping from the controller name to the controller's PCI address in the older release, and then compare this to the mapping in the newer release, to ensure that the device name is as expected.
The following is an example from /var/log/messages:
kernel: cciss0: <0x3230> at PCI 0000:1f:00.0 IRQ 71 using DAC
…
kernel: cciss1: <0x3230> at PCI 0000:02:00.0 IRQ 75 using DAC
If the device name is incorrect, add the pci=bfsort parameter to the kernel command line, and check again.

Enabling CHAP (Challenge-Handshake Authentication Protocol) on an iSCSI target for the be2iscsi driver results in kernel panic. To work around this issue, disable CHAP on the iSCSI target.
kernel component
Newer VPD (Vital Product Data) blocks can exceed the size the tg3 driver normally handles. As a result, some of the routines that operate on the VPD blocks may fail. For example, the nvram test fails when running the ethtool –t command on BCM5719 and BCM5720 Ethernet Controllers.
kernel component
Running the ethtool -t command on BCM5720 Ethernet controllers causes a loopback test failure because the tg3 driver does not wait long enough for a link.
kernel component
The tg3 driver in Red Hat Enterprise Linux 6.2 does not include support for Jumbo frames and TSO (TCP Segmentation Offloading) on BCM5719 Ethernet controllers. As a result, the following error message is returned when attempting to configure, for example, Jumbo frames:
SIOCSIFMTU: Invalid argument
kernel component
The default interrupt configuration for the Emulex LPFC FC/FCoE driver has changed from INT-X to MSI-X. This is reflected by the lpfc_use_msi module parameter (in /sys/class/scsi_host/host#/lpfc_use_msi) being set to 2 by default, instead of the previous 0.
Two issues provide motivation for this change: SR-IOV capability only works with the MSI-X interrupt mode, and certain recent platforms only support MSI or MSI-X.
However, the change to the LPFC default interrupt mode can bring out host problems where MSI/MSI-X support is not fully functional. Other host problems can exist when running in the INT-X mode.
If any of the following symptoms occur after upgrading to, or installing Red Hat Enterprise Linux 6.2 with an Emulex LPFC adapter in the system, change the value of the lpfc module parameter, lpfc_use_msi, to 0:
  • The initialization or attachment of the lpfc adapter may fail with mailbox errors. As a result, the lpfc adapter is not configured on the system. The following message appear in /var/log/messages:
    lpfc 0000:04:08.0: 0:0:0443 Adapter failed to set maximum DMA length mbxStatus x0
    lpfc 0000:04:08.0: 0:0446 Adapter failed to init (255), mbxCmd x9 CFG_RING, mbxStatus x0, ring 0
    lpfc 0000:04:08.0: 0:1477 Failed to set up hba
    ACPI: PCI interrupt for device 0000:04:08.0 disabled
    
  • While the lpfc adapter is operating, it may fail with mailbox errors, resulting in the inability to access certain devices. The following message appear in /var/log/messages:
    lpfc 0000:0d:00.0: 0:0310 Mailbox command x5 timeout Data: x0 x700 xffff81039ddd0a00
    lpfc 0000:0d:00.0: 0:0345 Resetting board due to mailbox timeout
    lpfc 0000:0d:00.0: 0:(0):2530 Mailbox command x23 cannot issue Data: xd00 x2
    
  • Performing a warm reboot causes any subsequent boots to halt or stop because the BIOS is detecting the lpfc adapter. The system BIOS logs the following messages:

The kdump kernel occasionally panics on a DELL PowerEdge R810 system with the i686 architecture.
kernel component
Running the LTP (Linux Testing Project) cgroup test suite on certain AMD systems causes NMI Watchdog to detect a hard LOCKUP and cause kernel panic.
kernel component, BZ#683012
High stress on 64-bit IBM POWER series machines prevents kdump from successfully capturing the vmcore. As a result, the second kernel is not loaded, and the system becomes unresponsive.
kernel component
Loading and unloading edac modules in a loop on certain HP systems may cause kernel panic.
kernel component
If the storage driver is loaded before multipathd is started, I/O errors occur. To work around this issue, use one of the following kernel command line parameters which are consumed by dracut:
rdloaddriver=scsi_dh_emc
or
rdloaddriver=scsi_dh_rdac
or
rdloaddriver=scsi_dh_emc,scsi_dh_rdac
The above command line parameters will cause the scsi_dh module to load before multipath is started.

Triggering kdump to capture a vmcore through the network using the Intel 82575EB ethernet device in a 32 bit environment causes the networking driver to not function properly in the kdump kernel, and prevent the vmcore from being captured.
kernel component, BZ#701857
Attempting to hibernate certain laptops, including Lenovo ThinkPad T400 and Lenovo ThinkPad X200, can cause kernel panic.
kernel component
On a system configured with an HP Smart Array controller, during the kdump process, the capturing kernel can become unresponsive and the following error message is logged:
NMI: IOCK error (debug interrupt?)
As a workaround, the system can be configured by blacklisting the hpsa module in a configuration file such as /etc/modules.d/blacklist.conf, and specifying the disk_timeout option so that saving the vmcore over the network is possible.
kernel component
Memory Type Range Register (MTRR) setup on some hyperthreaded machines may be incorrect following a suspend/resume cycle. This can cause graphics performance (specifically, scrolling) to slow considerably after a suspend/resume cycle.
To work around this issue, disable and then re-enable the hyperthreaded sibling CPUs around suspend/resume, for example:
#!/bin/sh
# Disable hyper-threading processor cores on suspend and hibernate, re-enable
# on resume.
# This file goes into /etc/pm/sleep.d/

In Red Hat Enterprise Linux 6.2, nmi_watchdog registers with the perf subsystem. Consequently, during boot, the perf subsystem grabs control of the performance counter registers, blocking OProfile from working. To resolve this, either boot with the nmi_watchdog=0 kernel parameter set, or run the following command to disable it at run time:
echo 0 > /proc/sys/kernel/nmi_watchdog
To re-enable nmi-watchdog, use the following command
echo 1 > /proc/sys/kernel/nmi_watchdog
kernel component, BZ#603911
Due to the way ftrace works when modifying the code during start-up, the NMI watchdog causes too much noise and ftrace can not find a quiet period to instrument the code. Consequently, machines with more than 512 CPUs will encounter issues with the NMI watchdog. Such issues will return error messages similar to BUG: NMI Watchdog detected LOCKUP and have either ftrace_modify_code or ipi_handler in the backtrace. To work around this issue, disable NMI watchdog by setting the nmi_watchdog=0 kernel parameter, or using the following command at run time:
echo 0 > /proc/sys/kernel/nmi_watchdog
kernel component
On 64-bit POWER systems the EHEA NIC driver will fail when attempting to dump a vmcore via NFS. To work around this issue, utilize other kdump facilities, for example dumping to the local file system, or dumping over SSH.

The kernel parameter, pci=noioapicquirk, is required when installing the 32-bit variant of Red Hat Enterprise Linux 6 on HP xw9300 workstations. Note that the parameter change is not required when installing the 64-bit variant.

2.11. Desktop

PackageKit component
Installing or updating packages signed with a GPG key not known or accessible to the system may throw PackageKit in a loop of password dialogues, repeatedly asking the user to confirm the installation of these packages from an untrusted source.
This issue may occur if additional third party repositories are configured on the system for which the GPG public key is not imported into the RPM database, nor specified in the respective Yum repository configuration. Official Red Hat Enterprise Linux repositories and packages should not be affected by this issue.
To work around this issue, import the respective GPG public key into the RPM database by executing the following command as root:
~]# rpm --import <file_containing_the_public_key>
gnome-power-manager component, BZ#748704

In some multi-monitor configurations (for example, dual monitors with both rotated), the cursor confinement code produces incorrect results. For example, the cursor may be permitted to disappear off the screen when it should not, or be prevented from entering some areas where it should be allowed to go. Currently, the only workaround for this issue is to disable monitor rotation.

Warning

This is only a partial build of the Package Updates. All errata that are included in this release are not in this document yet.

4.1. 389-ds-base

Updated 389-ds-base packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.
Bug Fixes
BZ#720458
If a server sent a response to an unbind request and the client simply closed the connection, Directory Server 8.2 logged "Netscape Portable Runtime error -5961 (TCP connection reset by peer.)".
BZ#752155
An incorrect SELinux context caused AVC errors in /var/log/audit/audit.log.
BZ#711266
The DS could not restart after a new object class was created which used the entryUSN attribute.
BZ#697663, BZ#700665, BZ#711533, BZ#711241, BZ#726136, BZ#700215
A number of memory leaks and performance errors were fixed.
BZ#712167
The ns-slapd process segfaulted if suffix referrals were enabled.
BZ#711513
A high volume of TCP traffic could cause the slapd process to quit responding to clients.
BZ#714298
Attempting to delete a VLV index caused the server to hang.
BZ#720051
Connections to the DS by an RSA authentication server using simple paged results by default would timeout.
BZ#735217
Running a simple paged search against a subtree with a host-based ACI would hang the server.
BZ#733443
If the target attribute list for an ACI had syntax errors and more than five attributes, the server crashed.
BZ#734267
It was not possible to set account lockout policies after upgrading from RHDS 8.1.
BZ#720452
Adding an entry with an RDN containing a % caused the server to crash.
BZ#709868
Only FIPS-supported ciphers can be used if the server is running in FIPS mode.
BZ#711265
It is possible to disable SSLv3 and only allow TLS.
BZ#713317, BZ#713318
If the changelog was encrypted and the certificate became corrupt, the server crashed.
BZ#733434
If the passwordisglobalpolicy attribute was enabled on a chained server, a secure connection to the master failed.
BZ#714310
If a chained database was replicated, the server could segfault.
BZ#694571
Editing a replication agreement to use SASL/GSS-API failed with GSS-API errors.
BZ#742611
In replication, a msgid may not be sent to the right thread, which caused "Bad parameter to an LDAP routine" errors. This causes failures to propagate up and halt replication.
BZ#701057
Password changes were replicated among masters replication, but not to consumers.
BZ#717066
If an entry was modified on RHDS and the corresponding entry was deleted on the Windows side, the sync operation attempts to use the wrong entry.
BZ#734831
Some changes were not properly synced over to RHDS from Windows.
BZ#726273
RHDS entries were not synced over to Windows if the user's CN had a comma.
BZ#718351
Intensive update loads on master servers could break the cache on the consumer, causing it to crash.
BZ#699458
Syncing a multi-valued attribute could delete all the other instances of that attribute when a new value was added.
BZ#729817
If a synced user subtree on Windows was deleted and then a user password was changed on the RHDS, the DS would crash.
Enhancements
BZ#742382
The nsslapd-idlistscanlimit configuration attribute can be set dynamically, instead of requiring a restart.
BZ#742661
Separate resource limits can be set for paged searches, independent of resource limits for regular searches.
BZ#720459
The sudo schema has been updated.
BZ#739959
A new configuration attribute sets a different list of replicated attributes for a total update versus an incremental update.
BZ#733440
A new configuration option allows the server to be started with an expired certificate.
BZ#720461
New TLS/SSL error messages have been added to the replication error log level.
Users are advised to upgrade to these updated 389-ds-base packages, which resolve these issues and add these enhancements.
Updated 389-ds-base packages that fix multiple bugs are now available.
389 Directory Server is an LDAPv3 compliant server. The base package includes the LDAP server and command-line utilities for server administration.
Bug Fixes
BZ#701554
Password changes did not replicate because the method used to pass the changes to consumer servers was rejected on the consumer. This issue has been corrected, and password changes now replicate as expected.
BZ#701556
Values could be lost when group memberships were synchronized between 389 Directory Server and Active Directory with the Windows Sync feature. The synchronization and modify operations have been altered to prevent this issue, allowing group updates to synchronize with Active Directory.
BZ#701558
The ldclt command-line testing tool crashed during LDAP ADD operations because an LDAP attribute was not set correctly, preventing the creation of entries that did not already exist. This update allows the LDAP ADD to proceed correctly.
BZ#701559
The server crashed if a long running task was started using the cn=tasks,cn=config interface and then the server was shut down before the task completed. This update prevents the server from crashing, but does not gracefully terminate the task, which can leave the server database in an inconsistent state. For example, the fixup-memberof.pl script invokes a tasks to fix up the memberOf attribute in group member entries. If the server is shut down before the task can complete, some entries may not have the correct memberOf values. Users should ensure that tasks are complete before shutting down the server to avoid inconsistency.
BZ#701560
When using the Entry USN feature, deleting an entry caused a memory leak via the entryusn attribute. This update fixes the memory leak.
All 389-ds-base users are advised to upgrade to these updated packages, which addresses these issues.

4.2. abrt

Updated abrt and libreport packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The abrt packages contain the Automatic Bug Reporting Tool (ABRT) version 2. In comparison with ABRT version 1, this version provides more flexible configuration, which covers a variety of customer use cases that the previous version was unable to cover. It also moves a lot of data processing from the daemon to separate tools that run without root privileges, which makes the daemon less error prone and the whole processing more secure.

Note

This update obsoletes the former report tool and replaces the report library to unify the reporting process in all Red Hat applications (Anaconda, setroubleshoot, ABRT).
The most interesting feature for end-users is the problem solution searching: when ABRT is configured to report to the Red Hat Customer Portal, it tries to search Red Hat problem databases (such as Knowledge Base or Bugzilla) for possible solutions and refers the user to these resources if the solution is found.

Bug Fixes

BZ#610603
The abrt-gui application used to list plug-ins multiple times if they were configured in the configuration file. This is now fixed.
BZ#627621
In the previous version of ABRT, a daemon restart was required for any changes in the configuration to take effect. In the new version, most of the options in the configuration file no longer require a restart.
BZ#653872
Support for retrace server has been added. Refer to https://fedorahosted.org/abrt/wiki/AbrtRetraceServer for more information about this new feature.
BZ#671354
By default, ABRT stores all problem information in the /var/spool/abrt/ directory. Previously, this path was hard coded and could not be changed in the configuration. With this update, this path can be changed in the /etc/abrt/abrt.conf configuration file.
BZ#671359
The previous documentation failed to cover some customer use cases. This error has been fixed, and all of these use cases are now covered in the Red Hat Enterprise Linux 6 Deployment Guide.
BZ#673173
In ABRT version 1, it was not possible to use wildcards to specify that some action should happen for any user. ABRT version 2 adds support for this functionality.
BZ#695416
The lacking information about configuring a proxy has been added to the Red Hat Enterprise Linux 6 Deployment Guide.
BZ#707950
Previously, a bug in ABRT version 1 was preventing a local Python build to finish. This is now fixed.
BZ#725660
The previous report tool and report library have been obsoleted by abrt and libreport. Users can notice the change in the problem reporting user interface of Anaconda, setroubleshoot, and ABRT.
All users of ABRT are advised to upgrade to these updated packages, which provide numerous bug fixes and enhancements.

4.3. acl

Updated acl packages that add two enhancements are now available for Red Hat Enterprise Linux 6.
Access Control Lists (ACLs) are used to define finer-grained discretionary access rights for files and directories. The acl packages contain the getfacl and setfacl utilities needed for manipulating access control lists.

Enhancements

BZ#720318
Prior to this update, the ACL library did not provide any function to check for extended ACLs of a file without following symbolic links. The only available function, acl_extended_file(), used to cause unnecessary mounts of autofs. This update introduces a new function, acl_extended_file_nofollow(), that checks for extended ACLs of a file without following symbolic links.
BZ#723998
Previously, the ACL library was linked without support for RELRO (read-only relocations) flags. With this update, the library is now linked with partial RELRO support.
Users of acl are advised to upgrade to these updated packages, which add these enhancements.
Updated acl packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
Access Control Lists (ACLs) are used to define finer-grained discretionary access rights for files and directories. The acl packages contain the getfacl and setfacl utilities needed for manipulating access control lists.

Bug Fixes

BZ#674883
Prior to this update, the setfacl.1 man page was not intelligible in that it did not state that removing a non-existent ACL entry is not considered to be an error. With this update, the setfacl.1 man page has been updated so that its content is now intelligible and exactly specifies the aforementioned behavior with regard to removing a non-existent ACL entry.
BZ#702638
Prior to this update, the package specification did not reflect a change of the upstream project web page address. This update corrects the respective address in the package specification.
All users of Access Control Lists should upgrade to these updated packages, which fix these bugs.

4.4. alsa-lib

Updated alsa-lib packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The alsa-lib packages contain libraries for the Advanced Linux Sound Architecture (ALSA).

Bug Fix

BZ#704772
Prior to this update, the alsa output plugin for the Audacious Audio Player did not work correctly. As a result, Audacious could under certain circumstances fail to generate any sound and display error messages. With this update, alsa-lib is modified so that Audacious can now generate sound as expected.
All alsa-lib users are advised to upgrade to these updated packages, which fix this bug.

4.5. anaconda

An updated anaconda package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.

4.6. apr

Updated apr packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The Apache Portable Runtime (APR) is a portability library used by the Apache HTTP Server and other projects. It provides a free library of C data structures and routines.
Security Fix
CVE-2011-1928
The fix for CVE-2011-0419 (released via RHSA-2011:0507) introduced an infinite loop flaw in the apr_fnmatch() function when the APR_FNM_PATHNAME matching flag was used. A remote attacker could possibly use this flaw to cause a denial of service on an application using the apr_fnmatch() function.

Note

This problem affected httpd configurations using the "Location" directive with wildcard URLs. The denial of service could have been triggered during normal operation; it did not specifically require a malicious HTTP request.
This update also addresses additional problems introduced by the rewrite of the apr_fnmatch() function, which was necessary to address the CVE-2011-0419 flaw.
All apr users should upgrade to these updated packages, which contain a backported patch to correct this issue. Applications using the apr library, such as httpd, must be restarted for this update to take effect.

4.7. atlas

Updated atlas packages that add various enhancements are now available for Red Hat Enterprise Linux 6.
The ATLAS (Automatically Tuned Linear Algebra Software) project is a research effort focusing on applying empirical techniques providing portable performance. The atlas packages provide C and Fortran77 interfaces to a portably efficient BLAS (Basic Linear Algebra Subprograms) implementation and routines from LAPACK (Linear Algebra PACKage).
The atlas packages have been upgraded to upstream version 3.8.4, which adds a number of enhancements over the previous version. The atlas package now contains subpackages optimized for Linux on IBM System z architectures. (BZ#694459)
All users of atlas are advised to upgrade to these updated packages, which add these enhancements.

4.8. attr

Updated attr packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
The attr packages provide extended attributes, which can be used to store system objects like capabilities of executables and access control lists, as well as user objects.

Bug Fixes

BZ#651119
Prior to this update, the setfattr utility could not restore the original values of the attributes when the "getfattr -e text" or "getfattr --encoding=text" command was used to dump attributes with embedded null characters. This update fixes the encoding of these values in getfattr to prevent information loss.
BZ#665049
Prior to this update, the getfattr utility followed symbolic links to directories even if the "-h" or "--no-dereference" option was specified. Additionally, the description in the getfattr(1) man page that related to this functionality was misleading. This update fixes getfattr with the "-h" option so that it no longer follows the symbolic links and the related content of the getfattr(1) man page is now correct.
BZ#665050
Prior to this update, the getfattr utility did not return a non-zero exit code when an attribute specified in the "getfattr" command did not exist. This update fixes getfattr so that it now returns a non-zero exit code when an attribute does not exist.
BZ#674870
Prior to this update, supported methods for encoding values of the extended attributes were not properly described in the setfattr(1) man page. This update adds the appropriate descriptions of the encoding methods to the setfattr(1) man page.
BZ#702639
Prior to this update, the project web page address as stated in the package specification did not reflect the change of the upstream project web page address. This update corrects the project web page address in the package specification.
BZ#727307
Prior to this update, the attr library was built without support for read-only relocations (RELRO) flags. With this update, the library is now built with partial RELRO support.
All users of attr are advised to upgrade to these updated packages, which fix these bugs.

4.9. audit

Updated audit packages that fix various bugs and add several enhancements are now available for Red Hat Enterprise Linux 6.
The audit packages contain the user space utilities for storing and searching the audit records which have been generated by the audit subsystem in the Linux 2.6 kernel.
The audit package has been upgraded to upstream version 2.1.3, which provides a number of bug fixes and enhancements over the previous version. (BZ#731723)

Bug Fixes

BZ#715279
Previously, the audit daemon was logging messages even when configured to ignore "disk full" and "disk error" actions. With this update, audit now does nothing if it is set to ignore these actions, and no messages are logged in the described scenario.
BZ#715315
Previously, the Audit remote logging client received a "disk error" event instead of "disk full" event from a server when the server's disk space ran out. This bug has been fixed and the logging client now returns the correct event in the described scenario.
BZ#748124
Prior to this update, the audit system was identifying the accept4() system call as the now deprecated paccept() system call. Now, the code has been fixed and audit uses the correct identifier for the accept4() system call.
BZ#709345
Previously, the "auditctl -l" command returned 0 even if it failed because of dropped capabilities. This bug has been fixed and a non-zero value is now returned if the operation is not permitted.
BZ#728475
When Kerberos support was disabled, some configuration options in the audisp-remote.conf file related to Kerberos 5 generated warning messages about GSSAPI support during boot. With this update, the options are now commented out in the described scenario and the messages are no longer returned.
BZ#700005
On i386 and IBM System z architectures, the "autrace -r /bin/ls" command returned error messages even though all relevant rules were added correctly. This bug has been fixed and no error messages about sending add rule data requests are now returned in the described scenario.
All audit users are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

4.10. augeas

Updated augeas packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
Augeas is a configuration editing tool. Augeas parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native config files.
The augeas packages have been upgraded to upstream version 0.9.0, which provides a number of bug fixes and enhancements over the previous version. (BZ#691483)

Bug Fix

BZ#693539
Previously, due to a bug in the source code, parsing invalid files failed silently without any error message. With this update, error messages are provided to inform users about the problem.
All users of Augeas are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

4.11. autofs

An updated autofs package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts file systems when you use them, and unmounts them when they are not busy.
Bug Fixes
BZ#704935
The autofs utility did not reset the map entry status on a reload request. As a result, newly added map entries that had previously recorded a mount failure failed to work. With this update, autofs resets the map entry status on a reload request and map entries are mounted as expected.
BZ#704939
The autofs utility could have terminated with a segmentation fault when attempting certain mounts. This occurred due to a race condition between mount handling threads for mounts that had previously recorded a mount failure. The automount cache map entry is now verified to be valid.
BZ#704940
The automount(8) man page referred to a non-existent man page. This was caused by a typographical error in the code. With this update, the man page reference has been corrected and the man page is displayed as expected.
BZ#704929
Due to a deadlock, autofs could stop responding when attempting to mount map entries that were nested within maps. With this update, the underlying code has been changed and, where possible, nested map entries mount correctly.
BZ#704933
Prior to this update, automount could terminate unexpectedly with a pthreads error. This occurred because attempts to acquire the master map lock occasionally failed as the lock was held by another thread. With this update, the underlying code has been adapted to wait for a short time before failing.
BZ#704927, BZ#704928
When retrieving paged results from an LDAP (Lightweight Directory Access Protocol) server, autofs handled certain cases incorrectly, which caused the query to not obtain all results. This update adds the code that handles these additional cases.
BZ#704937
Prior to this update, if a key entry of an automount map began with an asterisk (*) sign, the daemon failed with a segmentation fault because the sign was not matched correctly. With this update, such asterisk signs are handled correctly.
BZ#704228
When using GSSAPI authentication, the fact that an incorrect authentication host name was being used caused the connection to fail. This update now gets the correct host name for the connection.
BZ#692816
automount was not performing sufficient sanity checks of server names in its configuration. This update corrects the configuration entry parsing.
BZ#700136
Error reporting for invalid mount locations was unclear. This update improves the error reporting.
BZ#703332
When an automount map key is present in a file map and is also present in an included map source, if the file map entry was removed and a lookup performed before a re-load was issued, the map lookup would have failed. This update corrects the logic used to determine if the lookup needs to continue into included maps.
BZ#718927
When reloading maps that include a combination of direct and indirect maps, it was possible for automount to deadlock due to incorrect lock ordering.
BZ#725931
There was inadvertent use of a small amount of GPLv3-licensed code from Samba in autofs. While this was permissible, it would have entailed explicitly relicensing autofs from "GPLv2 or later" to "GPLv3", which is not intended for autofs at this time. Therefore, the Samba-derived code has been replaced in order to maintain the "GPLv2 or later" licensing status of autofs.
Enhancements
BZ#704416
This update adds the "--dumpmaps" option to the automount command, which allows you to dump the maps from their source as seen by the automount daemon.
BZ#704932
This update adds simple Base64 encoding for LDAP and thus allows hashing of the password entries in the /etc/autofs_ldap_auth.conf configuration file.
All autofs users are advised to upgrade to this updated package, which provides numerous bug fixes and enhancements.

4.12. autotrace

Updated autotrace packages that fix one bug are now available for Red Hat Enterprise Linux 6.
AutoTrace is a program for converting bitmaps to vector graphics. Supported input formats include BMP, TGA, PNM, PPM, and any format supported by ImageMagick, whereas output can be produced in PostScript, SVG, xfig, SWF, and others.
Bug Fix
BZ#658057
When installing autotrace-devel multilib RPM packages from the optional repository, file conflicts between these packages appeared, causing the installation transaction to abort. This problem has been fixed and the installation transaction now proceeds without conflicts.
All users of autotrace are advised to upgrade to these updated packages, which resolve this issue.

4.13. bacula

Updated bacula packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
Bacula is a set of programs that allow you to manage the backup, recovery, and verification of computer data across a network of different computers.

Bug Fixes

BZ#651776
Prior to this update, the bacula packages were not distributed with the applybaculadate file. As a result, the logwatch cron script failed. The problem has been fixed by including the applybaculadate file in the bacula packages so that the logwatch cron script now works as expected.
BZ#651780
Prior to this update, the make_catalog_backup.pl script created a MySQL configuration file, which had the file permissions set to world-writeable and world-readable so that MySQL did not accept the configuration file with these permissions and the MySQL database login configuration was not used. As a result, it was not possible to complete a MySQL database dump. With this update, the configuration file is now created with correct permissions, and the MySQL database login configuration is used by MySQL so that it is now possible to complete the MySQL database dump as expected.
BZ#651786
Prior to this update, there was no option to change Bacula's runtime user. As a consequence, Bacula was always run under the root user. The problem has been fixed by adding support for the bacula-dir, bacula-fd, and bacula-sd files in the /etc/sysconfig/ directory; these files can be used for specifying a non-root user and group with the DIR_USER, FD_USER, SD_USER, and DIR_GROUP, FD_GROUP and SD_GROUP options, respectively. With this update, Bacula can be run under the specified user.
BZ#651787
Prior to this update, when creating a symbolic link to the "bscan" utility, the new link was erroneously named "dbcheck". As a result, the already existing "dbcheck" symbolic link was overwritten by the erroneous one. Thus the "dbcheck" command ran the "bscan" utility so that it was not possible to execute the "bscan" utility with the "bscan" command. The problem has been fixed in this update so that the "dbcheck" and "bscan" utilities now work as expected.
BZ#657297
Prior to this update, Bacula's default configuration missed a required option. As a result, the Bacula tray monitor component terminated unexpectedly. The problem has been fixed by adding the "Address" option to the "Director" section in the Bacula tray monitor configuration file so that the Bacula tray monitor now works as expected with the default configuration file. Note that this bug fix does not alter any existing Bacula tray monitor configuration file. As a consequence, the Bacula tray monitor can terminate unexpectedly if the existing Bacula tray monitor configuration is incorrect.
BZ#689400
Prior to this update, the backup size was computed incorrectly under certain circumstances. As a consequence, the reported size of the incremental backup could have been wrong. The problem has been fixed by correcting the backup size computation process so that the size of the incremental backup is now reported correctly.
BZ#712794
Prior to this update, the shadow-utils package was not listed among the package dependencies for Bacula. As a result, the bacula user and bacula group were not created when the shadow-utils package was not present on the system, and a warning message was displayed during the bacula packages installation. This bug has been fixed by adding shadow-utils to the package dependencies.
BZ#712804
Prior to this update, the chkconfig package, which contains the "alternatives" utility, was not listed among the package dependencies for Bacula. As a result, the bacula-dir and bacula-sd services were not configured, the "alternatives" utility was not found, and Bacula's symbolic links were not created. These problems have been fixed by adding chkconfig to the package dependencies.
All users of Bacula are advised to upgrade to these updated packages, which fix these bugs.

4.14. bfa-firmware

An updated bfa-firmware package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.

BIND includes a DNS server (named), which resolves host names to IP addresses; a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating properly.

Bug Fixes

BZ#699951
Prior to this update, the code in libdns which sends DNS requests was not robust enough and suffered from a race condition. If a race condition occurred, the "named" name service daemon logged an error message in the format "zone xxx.xxx.xxx.in-addr.arpa/IN: refresh: failure trying master xxx.xxx.xxx.xxx#53 (source xxx.xxx.xxx.xxx#0): operation canceled" even when zone refresh was successful. This update improves the code to prevent a race condition in libdns and the error no longer occurs in the scenario described.
BZ#700097
A command or script traditionally gives a non-zero exit status to indicate an error. Prior to this update, the nsupdate utility incorrectly returned the exit status "0" (zero) when the target DNS zone did not exist. Consequently, the nsupdate command returned "success" even though the update failed. This update corrects this error and nsupdate now returns the exit status "2" in the scenario described.
BZ#725577
Prior to this update, named did not unload the bind-dyndb-ldap plugin in the correct places in the code. Consequently, named sometimes terminated unexpectedly during reload or stop when the bind-dyndb-ldap plugin was used. This update corrects the code, the plug-in is now unloaded in the correct places, and named no longer crashes in the scenario described.
BZ#693982
A non-writable working directory is a long time feature on all Red Hat systems. Previously, named wrote "the working directory is not writable" as an error to the system log. This update changes the code so that named now writes this information only into the debug log.
BZ#717468
The named initscript lacked the "configtest" option that was available in earlier releases. Consequently, users of the bind initscript could not use the "service named configtest" command. This update adds the option and users can now test their DNS configurations for correct syntax using the "service named configtest" command.
All users of bind are advised to upgrade to these updated packages, which fix these bugs.

4.16. bind-dyndb-ldap

An updated bind-dyndb-ldap package that fixes several bugs is now available for Red Hat Enterprise Linux 6.
The dynamic LDAP (Lightweight Directory Access Protocol) back end is a plug-in for BIND that provides an LDAP database back-end capabilities. It features support for dynamic updates and internal caching to lift the load off of the LDAP server.

Bug Fixes

BZ#742368
Previously, the bind-dyndb-ldap plug-in could faile to honor the selected authentication method because it did not call the ldap_bind() function on reconnection. Consequently, the plug-in connected to the LDAP server anonymously. With this update, the ldap_bind() function is executed on reconnection and the plug-in uses the correct authentication method in the described scenario.
BZ#707255
The bind-dyndb-ldap plug-in failed to load new zones from the LDAP server runtime. This update adds the zone_refresh parameter to the plug-in which controls how often the zone check is performed.
BZ#745045
The bind-dyndb-ldap plug-in could fail to connect to the LDAP server. This happened when the LDAP server was using localhost and FreeIPA installation was using a name different from the machine hostname. This update adds to the plug-in the ldap_hostname option, which can be used to set the correct LDAP server hostname.
BZ#727856
The "named" process could have remained unresponsive due to a race condition in the bind-dyndb-ldap plug-in. With this update, the race condition has been resolved and the problem no longer occurs.
All users of bind-dyndb-ldap are advised to upgrade to this updated package, which fixes these bugs.

4.17. binutils

An updated binutils package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
binutils is a collection of binary utilities, including ar (for creating, modifying and extracting from archives), as (a family of GNU assemblers), gprof (for displaying call graph profile data), ld (the GNU linker), nm (for listing symbols from object files), objcopy (for copying and translating object files), objdump (for displaying information from object files), ranlib (for generating an index for the contents of an archive), readelf (for displaying detailed information about binary files), size (for listing the section sizes of an object or archive file), strings (for listing printable strings from files), strip (for discarding symbols), and addr2line (for converting addresses to file and line).
Bug Fixes
BZ#664640
Prior to this update, the readelf utility added 0x40 into a character in order to display a non-printing character but did not do so when processing a multibyte character. As a result, the readelf utility did not display a multibyte character in the ELF header correctly. The code has been corrected and readelf no longer displays garbled characters when processing multibyte, or non-ASCII, characters.
BZ#674925
An unneeded patch to bineutils caused a large link time degradation when using the binutils --build-id command. This update removes that patch.
BZ#689829
An Operating System (OS) Application Binary Interface (ABI) describes the low-level interface between a program and the operating system (OS/ABI). The indirect meta-function, ifunc(), whose value can be determined at load time, allows for architecture dependent optimization. Prior to this update, the OS/ABI preprocessor macro was erroneously set to UNIX - Linux instead of UNIX - System V in an ELF header by a dynamic executable which used ifunc(). This update applies a backported patch which corrects the code and the error no longer occurs.
BZ#698005
Prior to this update, the binutils' strip command, which is run as part of the RPM build process, did not copy the EI_OSABI value in the ELF file header properly, it set the value to zero. Consequently, if the EI_OSABI field of the debug file had a value of 3 (ABI tag for GNU/Linux), in the stripped file it was erroneously set to 0 (UNIX - System V). This update corrects the problem and strip now leaves the field intact.
BZ#701586
On 64-bit PowerPC platforms, the position of -ldl in the list compiler options caused unexpected behavior when compiling C++ code. If -ldl was not placed at the end of parameter list, the GNU C Compiler (GCC) failed with an error in the format:
libtest.a(some_object_file.o): undefined reference to `.dlerror'
With this update, the code has been corrected and the GCC compiler functions as expected.
BZ#707387
When compiling C source code using the GNU C Compiler (GCC), a Table Of Contents (TOC), is created for every executable file. Prior to this update, compiling C++ code using GCC for 64-bit PowerPC, using -mcmodel=small -mno-minimal-toc as options, GNU linker, (ld), erroneously decided that if a section did not make use of the TOC it could belong to any TOC group. Consequently, when a local function call was made from one section of code to another section in the same object file, due to the two sections being assigned to different TOC groups, a failure occurred and an error message in the following format was logged.
libbackend.a(cse.o)(.text.unlikely+0x60): sibling call optimization to `.opd' does not allow automatic multiple TOCs; recompile with -mminimal-toc or -fno-optimize-sibling-calls, or make `.opd' extern
This update applies an upstream patch to improve the partitioning of sections of code, which make local function calls, into multiple TOC groups. As a result the error no longer occurs in the scenario described.

Note

It is necessary to relink executables and shared libraries containing objects which were compiled with -mcmodel=small -mno-minimal-toc. Therefore code should be recompiled by running these commands again after applying the update.
BZ#714824
Prior to this update, after compiling a kernel from source code with debugging information, some debug information was missing. Consequently, when using the GNU Project's debugger (GDB) utility, if a user issued the command l setup_arch to determine the target architecture, the following error was displayed.
No line number known for setup_arch
This update corrects the code and the GDB utility now correctly displays the architecture for which the code was compiled.
BZ#721079
Compilers used for producing code optimized for 64-bit PowerPC platforms use the default Red Hat Enterprise Linux system linker, ld, provided with the operating system to produce executables and libraries. Some object code generated by the IBM XL compiler caused ld to terminate unexpectedly with a segmentation fault. Consequently, users were not able to produce optimized executables or libraries. With this update, a backported patch has been applied to correct the problem and ld no longer crashes in the scenario described.
BZ#733122
When linking FORTRAN programs with the IBM XL compiler and the default Red Hat Enterprise Linux 6.1 system linker, ld sometimes terminated unexpectedly with a segmentation fault. This updates applies an upstream patch to correct the problem and ld no longer crashes in the scenario described.
BZ#747695
The assembler, as, when generating a memory reference to a local symbol plus or minus an offset, did not include the constant offset when generating 32-bit x86 code. Consequently, when the local symbol being referenced was defined before the instruction using the symbol with an offset, an error would occur. This update corrects the code and the problem no longer occurs.
Enhancements
BZ#696368
With this update, backported patches have been included to support new AMD processors.
BZ#696494
Certain Intel processors support a new RdRand instruction to generate a true random number in a short time. This update includes support for this new instruction.
Users of binutils are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
An updated binutils package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The binutils package is a collection of programming tools for the manipulation of object code in various object file formats.

Bug Fix

BZ#721079
Prior to this update, an input object file could have a non-empty .toc section but no references to the .toc entries because of a problem in the 64-bit PowerPC linker TOC editing code. As a result, various utilities of the binutils package terminated unexpectedly with a segmentation fault under certain conditions. This update handles local symbols in .toc sections correctly. Now, no more crashes occur.
Users of binutils are advised to upgrade to this updated package, which fixes this bug.

4.18. biosdevname

An updated biosdevname package that fixes several bugs and adds various enhancements are now available for Red Hat Enterprise Linux 6.
The biosdevname package contains an optional convention for naming network interfaces; it assigns names to network interfaces based on their physical location. The package is disabled by default, except for a limited set of Dell PowerEdge, C Series and Precision Workstation systems.
The biosdevname package has been upgraded to upstream version 0.3.11, which provides a number of bug fixes and enhancements over the previous version. (BZ#696203)

Bug Fixes

BZ#700248
When NPAR (NIC Partitioning) is enabled, the partition number should be appended as a suffix to the interface name. Previously, biosdevname did not add partition numbers to interface names, for example, instead of naming an interface "em3_1", the interface was named "em3". Consequently, partitioned network interfaces were missing the suffix necessary to describe the partition. Now, biosdevname correctly recognizes the VPD (Vital Product Data) suffix and full interface names are created correctly.
BZ#700251
When biosdevname ran in a guest environment, it suggested names to new network interfaces as if it was in a host environment. Consequently, affected network interfaces were incorrectly renamed. Now, biosdevname no longer suggests names in the described scenario.
BZ#729591
When biosdevname was reading VPD information to retrieve NPAR-related data, the read operations failed or became unresponsive on certain RAID controllers. Additionally, biosdevname sometimes attempted to read beyond the VPD boundary in the sysfs VPD file, which also resulted in a hang. This bug has been fixed and biosdevname now performs the read operation correctly in the described scenarios.
BZ#739592
Previously, the "--smbios" and "--nopirq" command-line parameters were missing in the biosdevname binary. Consequently, consistent network device naming could not be enabled because biosdevname exited without suggesting a name. This update adds support for these parameters and enables the device naming.
BZ#740532
Previously, NICs (Network Interface Cards) on biosdevname-compatible machines were given traditional "eth*" names instead of "em*" or "p*p*" names. This bug has been fixed and biosdevname now provides correct names for the NICs.

Enhancements

BZ#696252
With this update, "--smbios" and "--nopirq" command-line parameters have been added to biosdevname.
BZ#736442
The biosdevname man page has been updated to explain the functionality of the "--smbios" and "--nopirq" command-line parameters.
Users of biosdevname are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

The blktrace packages contain a number of utilities to record the I/O trace information for the kernel to user space, and utilities to analyze and view the trace information.

Bug Fix

BZ#705128
Prior to this update, the blkparse code contained a misprint. As a result, blkparse used the wrong variable when printing the PC Writes Completed. This update modifies the code so that blkparse now prints the correct value for PC Writes Completed.

Enhancement

BZ#736399
This update adds FLUSH/FUA support to blktrace.
All blktrace users are advised to upgrade to these updated packages, which fix this bug and add this enhancement.

4.20. bltk

An updated bltk package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The bltk (Battery Life Tool Kit) package includes binaries and scripts to test battery life.

Bug Fixes

BZ#618308
Prior to this update, the bltk tree was corrupted. As a result, the bltk_report script failed. This update modifies the settings of the bltk root path. Now, the report script works as expected.
BZ#679028
Prior to this update, bltk could be installed without requiring the gnuplot binary. As a result, the bltk_plot script exited with an error message when the gnuplot package was not installed and the charts were shown from measured data. This update requires the gnuplot package for its installation. Now, the bltk_plot script no longer exits with an error.
All bltk users are advised to upgrade to this updated package, which fixes these bugs.

4.21. boost

Updated boost packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Boost provides free peer-reviewed portable C++ source libraries, with emphasis on libraries which work well with the C++ Standard Library.

Bug Fix

BZ#723503
Prior to this update, the cyclic redundancy check (CRC) was not correctly computed on 64-bit architectures during decompression of gzip archives. In this update, constant-width integer types are used to compute CRC to make the results stable across all architectures.
Users of Boost are advised to upgrade to these updated packages which fix this bug.

4.22. ca-certificates

An updated ca-certificates package that fixes one security issue is now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important security impact.
This package contains the set of CA certificates chosen by the Mozilla Foundation for use with the Internet Public Key Infrastructure (PKI).
Security Fix
BZ#734381
It was found that a Certificate Authority (CA) issued fraudulent HTTPS certificates. This update removes that CA's root certificate from the ca-certificates package, rendering any HTTPS certificates signed by that CA as untrusted.
All users should upgrade to this updated package. After installing the update, all applications using the ca-certificates package must be restarted for the changes to take effect.

4.23. cachefilesd

An updated cachefilesd package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The cachefilesd package manages a kernel module that attempts to improve the performance of selected file systems by using local disk space to cache data read over the network.

Bug Fixes

BZ#660347
Prior to this update, cachefilesd used the wrong log level for cull info messages. As a result, the /var/log/messages file could become overloaded. This update reduces the messages to the debug level. Now, /var/log/messages no longer becomes overloaded.
BZ#723890
Prior to this update, cachefilesd depended on a specific version of the SELinux policy package. As a result, only the nominated version was allowed. This update permits the nominated version and any later versions. Now, the SELinux policy dependency works as expected.
All users of cachefilesd are advised to upgrade to this updated package, which fixes these bugs.

4.24. certmonger

An updated certmonger package that fixes multiple bugs is now available for Red Hat Enterprise Linux 6.
The certmonger service monitors certificates as the date at which they become invalid approaches, optionally attempting to re-enroll with a supported certificate authority (CA) to keep the services which use the certificates running without incident.

Bug Fixes

BZ#692766
Previously, the certmonger service could access a Network Security Services (NSS) database without a password, despite being configured to use a password to access that database. This behavior was not recognized as an error. This update correctly diagnoses this inconsistency as an error.
BZ#694184
Previously, if the certmonger service could not generate a key pair in an NSS database because it did not have the password that was required for accessing the database, the certmonger service did not recover when it was subsequently given the correct password. This update handles this case correctly.
BZ#697058
Previously, the certmonger service did not correctly diagnose a missing token if the name of the token to use was specified when the service was instructed to generate a key pair for storage in an NSS database. This update corrects this error.
BZ#712500
Previously, the certmonger service encountered an assertion failure if the D-Bus message bus service was not already running when certmonger was started. This update modifies the certmonger service so that no more assertion problems occur in such a situation.
BZ#721392
Previously, when the getcert command needed to report an error message which it received from the certmonger service, it exited unexpectedly due to a logic error. This update corrects the logic so that the error message is correctly reported.
BZ#727863
Previously, the certmonger service was not fully compatible with newer versions of the xmlrpc-c and libcurl packages. As a result, credentials could not be delegated when using GSSAPI authentication with a CA that was accessed via XML-RPC. This update includes the necessary changes to continue to be able to delegate credentials when using GSSAPI authentication with a CA that is accessed using XML-RPC, such as IPA.
BZ#699059, BZ#739903
Previously, when the getcert request command was given a location for key or certificate storage using a relative path, and the location did not exist, the error was only reported after multiple warnings during which the command attempted to convert the relative path to an absolute path. This update suppresses these warnings.
BZ#741262
Previously, an incorrect error message was displayed if the getcert resubmit command was invoked with the -i flag to specify which request should be resubmitted to a CA but no request that matched the provided value was present. This update displays the correct error message.
BZ#742348
Due to a logic error, attempts to save a newly-obtained certificate to an NSS database could fail intermittently. This update corrects the error.

Enhancements

BZ#698772
Previously, the getcert list command only printed information about every certificate and enrollment request being managed by certmonger, and there was no way to narrow down the results. This update includes an updated version of the command which can narrow the result set if the invoking user provides information about the location of the certificate or key in which the user is interested
BZ#750617
This update now includes an HTTP "Referer:" header value when submitting requests to CAs which are accessed using XML-RPC, as is expected to be required by future releases of the IPA CA.
All users of the certmonger service are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.
An updated certmonger package that fixes one bug is now available for Red Hat Enterprise Linux 6.1.
An updated certmonger package that fixes one bug is now available for Red Hat Enterprise Linux 6.1.
The certmonger service monitors certificates, warning of their impending expiration, and optionally attempting to re-enroll with supported CAs (Certificate Authorities).

Bug Fix

BZ#729803
When submitting a signing request to a Red Hat IPA (Identity, Policy, Audit) CA, certmonger is expected to authenticate using the client's host credentials, and to delegate the client's credentials to the server. Recent updates to libraries on which certmonger depends changed delegation of client credentials from a mandatory operation to an optional operation that is no longer enabled by default, which effectively broke certmonger's support for IPA CAs. This update gives certmonger the ability to explicitly request credential delegation when used with newer versions of these libraries, which introduce an API that allows certmonger to explicitly request that credential delegation be performed.
All certmonger users are advised to upgrade to this updated package, which fixes this bug.

4.25. cifs-utils

An updated cifs-utils package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The cifs-utils package contains utilities for mounting and managing CIFS shares.

Bug Fixes

BZ#676439
Prior to this update, mount.cifs dropped the CAP_DAC_READ_SEARCH flag together with most of the other capability flags before it performed a mount. As a result, mounting onto a directory without execute permissions failed if mount.cifs was installed as a setuid program and the user mount was configured in the /etc/fstab file. This update reinstates the CAP_DAC_READ_SEARCH flag before calling mount. Now, mounting no longer fails.
BZ#719363
Prior to this update, several mount options were missing from the mount.cifs(8) man page. With this update, the man page documents all mount options.
All users of cifs-utils are advised to upgrade to this updated cifs-utils package, which fixes these bugs.

4.26. cjkuni-fonts

Updated cjkuni-fonts packages that fix one bug are now available for Red Hat Enterprise Linux 6.
CJK Unifonts are Unicode TrueType fonts derived from original fonts made available by Arphic Technology under the Arphic Public License and extended by the CJK Unifonts project.

Bug Fix

BZ#682650
Prior to this update, when viewing the U+4190 CJK character with the AR PL UMing font and the font size 10, this character was not displayed properly. This bug has been corrected in this update so that the character is now correctly displayed as expected.
All users of cjkuni-fonts are advised to upgrade to these updated packages, which fix this bug.

4.27. cluster

Updated cluster and gfs2-utils packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The cluster packages contain the core clustering libraries for Red Hat High Availability as well as utilities to maintain GFS2 file systems for users of Red Hat Resilient Storage.
Bug Fixes
BZ#707115
The cluster and gfs2-utils packages have been upgraded to upstream version 3.0.12.1, which provides a number of bug fixes over the previous version.
BZ#713977
Previously, when a custom multicast address was configured, the configuration parser incorrectly set the default value of the time-to-live (TTL) variable for multicast packet to 0. As a consequence, cluster nodes were not able to communicate with each other. With this update, the default TTL value is set to 1, which fixes the problem.
BZ#726777
A section describing the "suborg" option for the fence_cisco_usc agent was not present in the RELAX NG schema which is used to validate the cluster.conf file. As a consequence, validation of cluster.conf failed even if the file was valid. The suborg section has been added to the RELAX NG schema and cluster.conf is now validated correctly.
BZ#707091
Building the resource group index for a new GFS2 file system using the mkfs.gfs2 utility used all the space allocated. If the file system filled up completely, no room was left to write a new rindex entry. As a consequence, the gfs2_grow utility was unable to expand the file system. The mkfs.gfs2 utility has been modified so that enough space is now allocated for the entire rindex file, and one extra rindex entry. The gfs2_grow source code has been modified to utilize the unused rindex space. As a result, gfs2_grow is now able to expand a completely full GFS2 file system.
BZ#678585
GFS2 POSIX (Portable Operating System Interface) lock operations (implemented in Distributed Lock Manager, also known as DLM) are not interruptible when they wait for another POSIX lock. Previously, processes that created a deadlock with POSIX locks could not be killed to resolve the problem, and one node had to be reset. DLM now uses a new kernel feature that allows the waiting process to be killed, and information about the killed process is now passed to the dlm_controld daemon to be cleaned up. Processes deadlocked on GFS2 POSIX locks can now be recovered by killing one or more of them.
BZ#719135
Prior to this update, boundaries for the locktable and label fields in the GFS2 superblock were not properly checked by the tunegfs2 tool. As a consequence, running the "gfs2_tool sb" command could terminate unexpectedly with buffer overflow. In addition, invalid characters could be printed when using tunegfs2 to change locktable or label to a minimum or maximum length (63 characters). The tunegfs tool has been modified to check the correct boundaries of the locktable and label fields. As a result, tunegfs2 no longer creates invalid locktables or labels, and therefore gfs2_tool prints the superblock values properly.
BZ#740385
When executing the cman utility by using the init script with enabled debugging, a file descriptor leaked. The file pointed to the file descriptor would continue to grow endlessly, filling up the /tmp file system. This update ensures that the file descriptor is closed after a successful cman startup. Space in /tmp is now released correctly.
BZ#695795
The cman utility implements a complex set of checks to configure the Totem protocol. One of the checks that copies the configuration data was incorrect and the transport protocol option was not handled correctly as a consequence. A patch has been applied to address this issue and cman now handles the transport option properly.
BZ#679566
When the user executed the "gfs2_edit savemeta" command to save the metadata for a target GFS2 file system, not all of the directory information was saved for large directories. If the metadata was restored to another device, the fsck.gfs2 tool found directory corruption because of a missing leaf block. This was due to gfs2_edit treating the directory leaf index (also known as the directory hash table) like a normal data file. With this update, gfs2_edit's savemeta function is modified to actually read all the data (the directory hash table) for large directories and traverse the hash table, saving all the leaf blocks. Now, all leaf blocks are saved properly.
BZ#679080
When the fsck.gfs2 tool was resolving block references and no valid reference was found, the reference list became empty. As a consequence, fsck.gfs2 check in pass1b terminated unexpectedly with a segmentation fault. With this update, pass1b is modified to check that the list is empty. The segmentation fault no longer occurs and fsck.gfs2 proceeds as expected.
BZ#731775
The dlm_controld daemon passed error results back to the kernel for POSIX unlock operations flagged with CLOSE. As a consequence, the kernel displayed the "dlm: dev_write no op" error messages, most of them when using non-POSIX locks, flocks. The dlm_controld daemon has been fixed to not pass error results to the kernel for POSIX unlock operations flagged with CLOSE. As a result, error messages no longer appear.
BZ#729071
Previously, the mount.gfs2 utility passed the "loop" option to the GFS2 kernel module which treated it as an invalid option. Mounting a GFS2 file system on loopback devices failed with an "Invalid argument" error message. With this update, mount.gfs2 is modified to avoid passing the "loop" option to the kernel. Mounting GFS2 systems on loopback devices now works as expected.
BZ#728230
Missing sanity checks related to the length of a cluster name caused the cman utility to fail to start. The correct sanity checks have been implemented with this update. The cman utility starts successfully and informs the user of the incorrect value of the cluster name, if necessary.
BZ#726065
The XML format requires special handling of certain special characters. Handling of these characters was not implemented correctly, which caused the cluster.conf file to not function as expected. Correct handling of the characters has been implemented and cluster.conf now works as expected.
BZ#706141
The exact device/mount paths were not compared due to incorrect logic in mount.gfs2 when trying to find mtab entries for deletion. The original entry was not found during remounts and therefore was not deleted. This resulted in double mtab entries. With this update, the realpath() function is used on the device/mount paths so that they match the content of mtab. As a result, the correct original mtab entry is deleted during a remount, and a replacement entry with the new mount options is inserted in its place.
BZ#720668
Previously, mkfs.gfs2 treated normal files incorrectly as if they were block devices. Attempting to create a GFS2 file system on a normal file caused mkfs.gfs2 to fail with a "not a block device" error message. Additional checks have been added so that mkfs.gfs2 does not call functions specific for block devices on normal files. GFS2 file systems can now be created on normal files. However, use of GFS2 in such cases is not recommended.
BZ#719126
The tunegfs2 command line usage message was not updated to reflect the available arguments which are documented in the man page. As a consequence, tunegfs2 printed an inaccurate usage message. The usage message has been updated and tunegfs2 now prints an accurate message.
BZ#719124
Previously, certain argument validation functions did not return error values, and tunegfs2 therefore printed confusing error messages instead of exiting quietly. Error handling has been improved in these validation functions, and tunegfs2 now exits quietly instead of printing the confusing messages.
BZ#694823
Previously, the gfs2_tool command printed the UUID (Universally Unique Identifier) output in uppercase. Certain applications expecting the output being in lowercase (such as mount) could have malfunctioned as a consequence. With this update, gfs2_tool is modified to print UUIDs in lowercase so that they are in a commonly accepted format.
BZ#735917
The qdisk daemon did not allow cman to upgrade the quorum disk device name. The quorum disk device name was not updated when the device was changed and, in very rare cases, the number of qdiskd votes would therefore not be correct. A new quorum API call has been implemented to update the name and votes of a quorum device. As a result, quorum disk device names and votes are updated consistently and faster than before.
BZ#683104
Prior to this update, the fsck.gfs2 utility used the number of entries in the journal index to look for missing journals. As a consequence, if more than one journal was missing, not all journals were rebuilt and subsequent runs of fsck.gfs2 were needed to recover all the journals. Each node needs its own journal; fsck.gfs2 has therefore been modified to use the "per_node" system directory to determine the correct number of journals to repair. As a result, fsck.gfs2 now repairs all the journals in one run.
BZ#663397
Previously, token timeout intervals of corosync were larger than the time it took a failed node to rejoin the cluster. Consequently, corosync did not detect that a node had failed until it rejoined. The failed node had been added again before the dlm_controld daemon asked corosync for the new member list, but dlm_controld did not notice this change. This eventually caused the DLM (Distributed Lock Manager) lockspace operations to get stuck. With this update, dlm_controld can notice that a node was removed and added between checks by looking for a changed incarnation number. Now, dlm_controld can properly handle nodes that are quickly removed and added again during large token timeouts.
BZ#732991
Previously, if a cluster was configured with a redundant corosync ring, the dlm_controld daemon would log harmless EEXIST errors, "mkdir failed: 17". This update removes these error messages so that they no longer appear.
Enhancements
BZ#733345
The corosync IPC port allows, when configured correctly, non-privileged users to access corosync services. Prior to this update, the cman utility did not handle such connections correctly. As a consequence, users were not able to configure unprivileged access to corosync when it was executed using cman. This update adds support to cman to configure unprivileged access. As a result, configured users and groups can now access corosync services without root privileges.
BZ#680930
This update introduces dynamic schema generation, which provides a lot of flexibility for end users. Users can plug into Red Hat Enterprise Linux High Availability Add-On custom resource and fence agents, and still retain the possibility to validate their cluster.conf file against those agents.
BZ#732635, BZ#735912
This update adds support for Redundant Ring Protocol, which aligns the default configuration of cman with corosync. Note that this enhancement is included as a Technology Preview.
BZ#702313
Previously, gfs2_edit saved GFS2 metadata uncompressed. Saved GFS2 metadata sets could have filled up a lot of storage space, and transferring them (for example, for support and debugging) would be slow. This update adds gzip compression to the metadata saving and restoring functions of gfs2_edit. GFS2 metadata sets are now compressed when saving and decompressed when restoring them. The user can specify the compression level with a command line option.
BZ#704178
With this update, the tunegfs2 utility replaces the superblock manipulating feature of gfs2_tool.
BZ#673575
Previously, the fence_scsi agent did not reboot a node when it was fenced. As a consequence, the node had to be rebooted manually before rejoining the cluster. This update provides a script for detecting loss of SCSI reservations. This can be used in conjunction with the watchdog package in order to reboot a failed host.
Users of cluster and gfs2-utils are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
Updated cluster and gfs2-utils packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The Red Hat Cluster Manager is a collection of technologies working together to provide data integrity and the ability to maintain application availability in the event of a failure. Using redundant hardware, shared disk storage, power management, and robust cluster communication and application failover mechanisms, a cluster can meet the needs of the enterprise market.

Bug Fix

BZ#728247
Prior to this update, the "suborg" option was not allowed by the cluster configuration schema defined in the /usr/share/cluster/cluster.rng file. As a consequence, when the "suborg" option was specified for the fence_cisco_ucs agent, the cluster refused to validate the configuration schema. The "suborg" option is now properly recognized, which fixes the problem.
All users of cluster and gfs2-utils are advised to upgrade to these updated packages, which resolve this bug.
Updated cluster and gfs2-utils packages that fix one bug are now available for Red Hat Enterprise Linux 6.

Bug Fix

BZ#720100
Previously, when a custom multicast address was configured, the configuration parser incorrectly set the default value of the time-to-live (TTL) variable for multicast packet to 0. Consequently, cluster nodes could not communicate with each other. With this update, the default TTL value is set to 1, thus fixing this bug.
Users of cluster and gfs2-utils are advised to upgrade to these updated packages, which fix this bug.

4.28. clustermon

Updated clustermon packages that fix a bug and add an enhancement are now available for Red Hat Enterprise Linux 6.
The clustermon packages are used for remote cluster management.

Bug Fix

BZ#634373
Previously, the clustermon tool failed to shut down nodes if the user had mounted a GFS2 file system that was not listed in the /etc/fstab file. This was caused by clustermon relying on the rgmanager tool and the GFS2 init scripts to unmount all file systems, but the cluster stack would not stop properly if the user mounted the file system manually. This has been fixed: clustermon now ensures that there are no cluster file systems mounted and then attempts to stop the cluster stack.

Enhancement

BZ#724978
The "get_cluster_schema" function call has been added to allow users to easily get the XML cluster schema content.
All users of clustermon are advised to upgrade to this updated packages, which resolves this bug.

4.29. coolkey

An enhanced coolkey package is now available for Red Hat Enterprise Linux 6.
The coolkey package contains driver support for CoolKey and Common Access Card (CAC) smart card products.

Enhancements

BZ#578690
This update adds support for Personal Identity Verification (PIV) smart cards.
BZ#700907
Common Access Cards (CAC) are defined to have exactly three certificates. However, some cards that used the CAC interface supplied one or two certificates only, which may have caused the coolkey utility to fail. CAC smart cards that contain less than three certificates are now supported.
Users of PIV and CAC smart cards are advised to upgrade to this updated package, which adds these enhancements.

4.30. coreutils

Updated coreutils packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The coreutils packages contain the core GNU utilities. These packages combine the old GNU fileutils, sh-utils, and textutils packages.

Bug Fixes

BZ#691292
Prior to this update, SELinux appeared to be disabled when building coreutils in Mock. As a result, coreutils did not build. With this update, SELinux determines more precisely whether it is disabled or not. Now, the packages are built successfully.
BZ#703712
Previously, incorrect signal handling could cause various problems for tcsh users logging into the root shell using the su utility. Signal masking in the subshell called by the su utility has been modified to respect the SIGTSTP signal as well as the SIGSTOP signal.
BZ#715557
When using the "-Z/--context" option in the cp utility, the SELinux context of a file was not changed if the file destination already existed. The utility has been modified and the context is changed as expected. However, this option is not portable to other systems.
BZ#720325
Prior to this update, the acl_extended_file() function could cause unnecessary mounts of autofs when using the ls command on a directory with autofs mounted. This update adds the new acl function, acl_extended_file_nofollow(), to prevent unnecessary autofs mounts.
BZ#725618
The description of the "--sleep-interval" option in the tail(1) manual page has been improved to be clearer about the behavior and to match the upstream version of coreutils.
All users of coreutils are advised to upgrade to these updated packages, which fix these bugs.

4.31. corosync

Updated corosync packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.
Bug Fixes
BZ#677583
Prior to this update, the corosync-blackbox command could, under certain circumstances, produce a backtrace in the output and consequently terminate with a segmentation fault. With this update, Corosync creates correct fdata files and also corosync-fplay is more resistant when dealing with incorrect fdata files.
BZ#677583
Prior to this update, cpg did not use the "left_nodes" field in the downlist message. As a consequence, a node could miss a configuration change and report larger old_members than expected if one node was paused. This update modifies the downlist so that the "left_nodes" field is used. Now, the membership events are correct.
BZ#692620
Prior to this update, cpg did not use the "left_nodes" field in the downlist message. As a consequence, a node could miss a configuration change and report larger old_members than expected if one node was paused. This update modifies the downlist so that the "left_nodes" field is used. Now, the membership events are correct.
BZ#696883
Prior to this update, running Corosync could cause a segmentation fault on multiple nodes when executed via CMAN. This update modifies the code so that executing Corosync via CMAN no longer causes segmentation faults with the pacemaker test suite.
BZ#696887
Prior to this update, the reference counting on the configuration server in Corosync was incorrect. As a consequence, terminating the corosync-cfgtool -r command before completing caused a segmentation fault. This update adds the correct reference counting for each architecture. Now, Corosync no longer encounters segmentation faults in this situation.
BZ#707860
Prior to this update, Corosync could terminate with a segmentation fault if it ran out of available open files. This update handles the maximum number of open files more gracefully. Now, Corosync no longer crashes when going over open file limits.
BZ#707867
Prior to this update, corosync-objctl could not create a new object/key and display double or float values. This update adds float and double support to corosync-objctl. Now, corosync-objctl can display object values with double or float types.
BZ#707873
Prior to this update, Corosync could terminate with a segmentation fault if it encountered a negative value for the message type on systems where char is signed. This update improves the check of the message type for incoming messages.
BZ#707875
Prior to this update, an error message was wrongly displayed if files in the service.d directory differed from the service key. With this update, Corosync longer checks for sub parameters in files in the service.d directory. Now, files in service.d directory can contain every possible configuration option.
BZ#709758
Prior to this update, Corosync used a spinlock around I/O operations. As a consequence, Corosync consumed an extremely high portion of the central processing unit (CPU) when running a large amount of inter-process communication (IPC) operations because the spinlocks would spin during I/O. This update replaces the spinlock with a mutual exclusion (mutex), which releases the processor from spinning but enforces correct behavior.
BZ#712115
Prior to this update, an incorrect mutex in the internal confdb data storage system could, under certain circumstances, cause Corosync to terminate with a segmentation fault. This update corrects the mutex and objdb API iteration no longer causes Corosync to terminate with a segmentation fault.
BZ#712188
Prior to this update, Corosync became locked with contrived test cases when the tracking functionality of the internal object database was enabled if it was under heavy load. This update modifies Corosync so that the tracking functionality under heavy load no longer causes Corosync to lock up.
BZ#725058
Prior to this update, retransmit list errors could occur on slower hardware due to high multicast traffic and slow CPU usage. This update processes the multicast buffer queue more frequently and retransmit errors are now less probable.
BZ#732698
Prior to this update, Corosync sometimes terminated unexpectedly when Corosync ran the cman_tool join and cman_tool leave commands in a loop. This update modifies the code so that no more segmentation faults occur in such situations.
Enhancements
BZ#529136
Prior to this update, the protocol in Corosync unnecessarily copied memory on AMD64 and EM64T architectures to align data structures for architectures which do not handle alignment correctly. As a consequence, the utilization of the central processing unit (CPU) was increased. This update can conditionally avoid copies on unaligned safe architectures such as Intel 80386, AMD64, and EM64T architectures. Now the CPU utilization is reduced by around 20%.
BZ#599327
Prior to this update, no diagnostic message was available when the multicast was blocked. As a consequence, each partition lost quorum which never remerged. This update displays a diagnostic warning that the node can not exit the GATHER state when a local NIC (network interface card) fault occurs or the firewall prevents totem from forming a cluster. In addition, the runtime.totem.pg.mrp.srp.firewall_enabled_or_nic_failure key is now set to 1.
BZ#667652
Prior to this update, fenced nodes where not safely powered up due to issues with the boot sequence. As a consequence, users had to skip cluster services at boot to avoid problems such as long response times and fences in two-node clusters. With this update, setting the nocluster boot parameter prevents Corosync to start automatically.
BZ#688260
Prior to this update, configuring two rings with different IP subnets only duplicated the IP address data of one ring. This update adds support for the redundant ring functionality to Corosync as a Technology Preview.
BZ#707876
Prior to this update, the corosync init script did not depend on syslog. As a consequence, syslog logging did not work if the user turned off syslog. This update adds syslog as a dependency to the init script. Now, logging works in all cases.
BZ#722469
Prior to this update, configuring two rings with different IP subnets only duplicated the IP address data of one ring. This update adds support for the redundant ring functionality to Corosync as a Technology Preview.
All corosync users are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
Updated corosync packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

Bug Fixes

BZ#726608
Previously, under heavy traffic, receive buffers sometimes overflowed, causing loss of packets. Consequently, retransmit list error messages appeared in the log files. This bug has been fixed, incoming messages are now processed more frequently, and the retransmit list error messages no longer appear in the described scenario.
BZ#727962
Previously, when a combination of a lossy network and a large number of configuration changes was used with corosync, corosync sometimes terminated unexpectedly. This bug has been fixed, and corosync no longer crashes in the described scenario.
BZ#734997
Prior to this update, when corosync ran the "cman_tool join" and "cman_tool leave" commands in a loop, corosync sometimes terminated unexpectedly. This bug has been fixed, and corosync no longer crashes in the described scenario.
All users of corosync are advised to upgrade to these updated packages, which fix these bugs.

4.32. cpufrequtils

An updated cpufrequtils package that fixes a bug is now available for Red Hat Enterprise Linux 6.
The cpufrequtils package contains utilities that can be used to control the cpufreq interface provided by the kernel on hardware that supports CPU frequency scaling.

Bug Fix

BZ#675734
Prior to this update, the cpufreq-aperf utility did not run on 32-bit systems due to an incorrect argument passed to the read() call. This problem has been fixed: the buffer size is now used instead of the size of the pointer and the cpufreq-aperf utility runs as expected.
All users of cpufrequtils are advised to upgrade to this updated package, which resolves this bug.

4.33. crash

An updated crash package that fixes various bugs and adds several enhancements is now available for Red Hat Enterprise Linux 6.
The crash package provides a self-contained tool that can be used to investigate live systems, and kernel core dumps created from the netdump, diskdump, kdump, and Xen/KVM "virsh dump" facilities from Red Hat Enterprise Linux.
BZ#710193
The crash package has been upgraded to upstream version 5.1.8, which provides a number of enhancements and bug fixes over the previous version.

Bug Fixes

BZ#705142
Previously, compressed kdump dump files were handled incorrectly on AMD64 and Intel 64 architectures if a system contained more than 454 CPUs. In such a case, the crash session terminated during initialization with the "crash: compressed kdump: invalid nr_cpus value: [cpus]" error message. A patch has been provided to address this issue, and the compressed dump files are now handled properly, thus fixing this bug.
BZ#716931
When the first chunk of physical memory on a system was assigned to NUMA (Non-Uniform Memory Architecture) node 1 (typically it is assigned to NUMA node 0), the "kmem -s" or "kmem -S" command incorrectly showed all cache blocks allocated by the slab allocator as empty. This bug has been fixed, and the kmem command now shows populated kmem_cache slab data correctly.
BZ#712214
In a rare scenario, a non-crashing CPU received a shutdown NMI (non-maskable interrupt) immediately after receiving an interrupt from another source. Because the IRQ entry-point symbols "IRQ0x00_interrupt" through "IRQ0x##_interrupt" no longer existed, the bt command terminated with the "bt: cannot transition from exception stack to current process stack" error message on AMD64 and Intel 64 architectures. This bug has been fixed, and backtrace now properly transitions from the NMI stack back to the interrupted process stack.

Enhancements

BZ#695413
The crash.8 man page and the associated built-in "crash -h" output have been re-written. The crash.8 man page now clarifies the required invocation options, adds all of the rarely-used command line options that have proliferated over the years, and updates the ENVIRONMENT variables section. The "crash -h" output now closely mimics the relevant parts of the crash.8 man page.
BZ#703467
With this update, the new "--osrelease [dump_file]" command line option that displays the OSRELEASE vmcoreinfo string from a kdump dump file has been added.
Users of crash are advised to upgrade to this updated package which fixes these bugs and adds these enhancements.

4.34. crontabs

An updated crontabs package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The crontabs package contains root crontab files and directories. You will need to install the cron daemon to run the jobs from crontabs. The cron daemon such as cronie or fcron checks the crontab files to see when particular commands are scheduled to be executed. If commands are scheduled, it executes them. Crontabs handles a basic system function, so it should be installed on your system.

Bug Fix

BZ#609544
Prior to this update, an example included in the /etc/crontab file contained an omission. It did not state that defining a job in crontab requires a username to be defined. The missing information has been added to the /etc/crontab file in this update.
All users of crontabs are advised to upgrade to this updated package, which fixes this bug.

4.35. cryptsetup-luks

Updated cryptsetup-luks packages that fix several bugs and add an enhancement are now available for Red Hat Enterprise Linux 6.
The cryptsetup-luks packages provide a utility which allows users to set up encrypted devices with the Device Mapper and the dm-crypt target.

Bug Fixes

BZ#713410
When the cryptsetup or libcryptsetup utility was run in FIPS (Federal Information Processing Standards) mode, the "Running in FIPS mode." message was displayed during initialization of all commands. This sometimes caused minor issues with associated scripts. This bug has been fixed and the message is now displayed only in verbose mode.
BZ#732179
Prior to this update, several directives were missing in cryptsetup status command implementation. Therefore, the cryptsetup status command always returned the exit code 0 when verifying the status of a mapped device. To fix this issue, the code has been modified. The cryptsetup status command now returns the 0 value only if the device checked is active.

Enhancement

BZ#701936
Previously, the libcryptsetup crypt_get_volume_key() function allowed to perform an action not compliant with FIPS. To conform FIPS requirements, the function is now disabled in FIPS mode and returns an EACCES error code to indicate it. Note that the "luksDump --dump-master-key" command and the key escrow functionality of the volume_key package are also disabled in FIPS mode as a consequence of this update.
All users of cryptsetup-luks are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

The ctdb packages have been upgraded to upstream version 1.0.114, which provides a number of bug fixes over the previous version. (BZ#701944)

Bug Fixes

BZ#728545
Prior to this update, the ctdb daemon leaked a file descriptor to anon_inodefs. This update modifies ctdb so that this file discriptor can no longer leak.

Enhancement

BZ#672641
This update adds support for Clustered Samba on top of GFS2 as a Technology Preview.
All users of ctdb are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

4.37. cups

Updated cups packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX operating systems.
Security Fix
CVE-2011-2896
A heap-based buffer overflow flaw was found in the Lempel-Ziv-Welch (LZW) decompression algorithm implementation used by the CUPS GIF image format reader. An attacker could create a malicious GIF image file that, when printed, could possibly cause CUPS to crash or, potentially, execute arbitrary code with the privileges of the "lp" user.

Bug Fixes

BZ#681836
Previously CUPS was not correctly handling the language setting LANG=en_US.ASCII. As a consequence lpadmin, lpstat and lpinfo binaries were not displaying any output when the LANG=en_US.ASCII environment variable was used. As a result of this update the problem is fixed and the expected output is now displayed.
BZ#706673
Previously the scheduler did not check for empty values of several configuration directives. As a consequence it was possible for the CUPS daemon (cupsd) to crash when a configuration file contained certain empty values. With this update the problem is fixed and cupsd no longer crashes when reading such a configuration file.
BZ#709896
Previously when printing to a raw print queue, when using certain printer models, CUPS was incorrectly sending SNMP queries. As a consequence there was a noticeable 4-second delay between queueing the job and the start of printing. With this update the problem is fixed and CUPS no longer tries to collect SNMP supply and status information for raw print queues.
BZ#712430
Previously when using the BrowsePoll directive it could happen that the CUPS printer polling daemon (cups-polld) began polling before the network interfaces were set up after a system boot. CUPS was then caching the failed hostname lookup. As a consequence no printers were found and the error, "Host name lookup failure", was logged. With this update the code that re-initializes the resolver after failure in cups-polld is fixed and as a result CUPS will obtain the correct network settings to use in printer discovery.
BZ#735505
The MaxJobs directive controls the maximum number of print jobs that are kept in memory. Previously, once the number of jobs reached the limit, the CUPS system failed to automatically purge the data file associated with the oldest completed job from the system in order to make room for a new print job. This bug has been fixed, and the jobs beyond the set limit are now properly purged.
BZ#744791
The cups init script (/etc/rc.d/init.d/cups) uses the daemon function (from /etc/rc.d/init.d/functions) to start the cups process, but previously it did not source a configuration file from the /etc/sysconfig/ directory. As a consequence, it was difficult to cleanly set the nice level or cgroup for the cups daemon by setting the NICELEVEL or CGROUP_DAEMON variables. With this update, the init script is fixed.
All users of CUPS are advised to upgrade to these updated packages, which contain backported patches to resolve these issues. After installing this update, the cupsd daemon will be restarted automatically.
Updated cups packages that fix a bug are now available for Red Hat Enterprise Linux 6.
The Common UNIX Printing System (CUPS) provides a portable printing layer for Linux, UNIX, and similar operating systems.

Bug Fix

BZ#736304
The MaxJobs directive controls the maximum number of print jobs that are kept in memory. Previously, once the number of jobs reached the limit, the CUPS system failed to automatically purge the oldest completed job from the system to make room for a new one. This bug has been fixed, and the jobs beyond the limit are now properly purged in the described scenario.
All users of cups are advised to upgrade to these updated packages, which fix this bug.

4.38. curl

Updated curl packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
cURL provides the libcurl library and a command line tool for downloading files from servers using various protocols, including HTTP, FTP, and LDAP.
Security Fix
CVE-2011-2192
It was found that cURL always performed credential delegation when authenticating with GSSAPI. A rogue server could use this flaw to obtain the client's credentials and impersonate that client to other servers that are using GSSAPI.
Users of curl should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications using libcurl must be restarted for the update to take effect.
Updated curl packages that resolve an issue are now available Red Hat Enterprise Linux 6.
The curl packages provide the libcurl library and the cURL command line tool for transferring data using various protocols, including HTTP, FTP, FILE, LDAP, TELNET, TFTP, SCP. Both, libcurl and cURL, support many useful capabilities, such as user authentication, proxy support, FTP uploading, HTTP POST and PUT methods, SSL certificates, and file transfer resume.

Bug Fix

BZ#727884
As a solution to a security issue, GSSAPI credential delegation was disabled, which broke the functionality of the applications that were relying on delegation, which was incorrectly enabled by libcurl. To fix this issue, the CURLOPT_GSSAPI_DELEGATION libcurl option has been introduced in order to enable delegation explicitly when applications need it. All applications using GSSAPI credential delegation can now use this new libcurl option to be able to run properly.
All users of cURL and libcurl are advised to upgrade to these updated packages, which resolve this issue. All running applications using libcurl have to be restarted for the update to take an effect.

4.39. cyrus-imapd

Updated cyrus-imapd packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and Sieve support.
Security Fix
CVE-2011-1926
It was discovered that cyrus-imapd did not flush the received commands buffer after switching to TLS encryption for IMAP, LMTP, NNTP, and POP3 sessions. A man-in-the-middle attacker could use this flaw to inject protocol commands into a victim's TLS session initialization messages. This could lead to those commands being processed by cyrus-imapd, potentially allowing the attacker to steal the victim's mail or authentication credentials.
Users of cyrus-imapd are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, cyrus-imapd will be restarted automatically.
Updated cyrus-imapd packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.

CVE-2011-3481
A NULL pointer dereference flaw was found in the cyrus-imapd IMAP server, imapd. A remote attacker could send a specially-crafted mail message to a victim that would possibly prevent them from accessing their mail normally, if they were using an IMAP client that relies on the server threading IMAP feature.
Red Hat would like to thank the Cyrus IMAP project for reporting the CVE-2011-3372 issue. Upstream acknowledges Stefan Cornelius of Secunia Research as the original reporter of CVE-2011-3372.
Users of cyrus-imapd are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, cyrus-imapd will be restarted automatically.

4.41. dbus

Updated dbus packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility.
Security Fix
CVE-2011-2200
A denial of service flaw was found in the way the D-Bus library handled endianness conversion when receiving messages. A local user could use this flaw to send a specially-crafted message to dbus-daemon or to a service using the bus, such as Avahi or NetworkManager, possibly causing the daemon to exit or the service to disconnect from the bus.
All users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.

4.42. device-mapper-multipath

Updated device-mapper-multipath packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The device-mapper-multipath packages provide tools to manage multipath devices using the device-mapper multipath kernel module.
Bug Fixes
BZ#677449
DM Multipath removed a device if it failed to check the device status due to insufficient memory. This happened because the command checking if the device map existed failed as the system returned an error. With this update, Multipath no longer returns an error under these circumstances and no devices are removed if the system runs out of memory while checking device status.
BZ#678673
If a device-mapper-multipath device was open but all attached device paths had been lost, the device was unable to create a new table with no device paths. As a concequence the multipath -ll command returned output indicating that no paths to the device were available with confusing "failed faulty running" rows presenting the missing paths. Multipath devices now reload tables with no device paths correctly.
BZ#689504
Device paths could fail even if unavailable only temporarily. This happened because the RDAC (Redundant Disk Array Controller) checker function did not recheck the status of hosts if it had received a temporary error code. The function now rechecks the path after it has received such error codes and the path failures are transient as expected.
BZ#697386
A previous bug fix introduced a race condition between the main thread and the thread running the checkerloop routine as the checkerloop thread was created with deferred cancellation type. The checkerloop thread continued running and attempted to access a property, which had been previously unallocated by the main thread. This caused the multipathd daemon to shutdown with a segmentation fault. Now the checkerloop thread checks if a shutdown is in progress and the deamon shuts down gracefully.
BZ#700169
The Multipath daemon failed to include some ghost paths when counting the number of active paths; however, when the ghost paths failed, they were subtracted from the number of active paths. This caused multipathd to fail IO requests even though some paths were still available. The Multipath daemon now counts ghost paths correctly and no longer fails IO requests while there are still active paths available.
BZ#705854
If the user set dev_loss_tmo to a value greater than 600 in multipath.conf without setting the fast_io_fail_tmo value, the multipathd daemon did not notify the user that fast_io_fail_tmo was not set. Multipath now issues a warning that fast_io_fail_tmo is not set under such circumstances.
BZ#706555
On shared-storage multipath setups that set failback to manual, multipath could keep alternating from the failover pathgroup to the primary pathgroup infinitely. This happened because multipath was incorrectly failing back to the primary pathgroup whenever a path priority changed. With this update, multipath no longer fails back to the primary pathgroup when a path's priority changes under such circumstances.
BZ#707560
If the multipath device was deleted while a path was being checked, multipathd did not abort the path check and terminated unexpectedly when trying to access the multipath device information. The Multipath daemon now aborts any path checks when the multipath device is removed and the problem no longer occurs.
BZ#714821
The Multipath daemon was removing a multipath device twice. This could cause multipathd to access memory already used for another purpose, and caused the multipathd daemon to terminate unexpectedly. The multipathd daemon now removes the device once and the problem no longer occurs.
BZ#719571
The kpartx utility built partition devices for invalid GUID partition tables (GPT) because it did not validate the size of GUID partitions. The kpartx utility now checks the partition size, and does not build devices for invalid GPTs.
BZ#723168
Multipath previously returned an unclear error message when it failed to find rport_id. The returned message and its severity have been adjusted.
BZ#725541
Several upstream commits have been included in the device-mapper-multipath package providing a number of bug fixes and enhancements over the previous version.
BZ#738298
Anaconda failed to recognize an existing filesystem on a zSeries Linux fibre-channel adapter (zFCP) LUN and marked it as 'Unknown' when reinstalling the system. This happened due to an incorrect setting of the DM_UDEV_DISABLE_DISK_RULES_FLAG property. Filesystem on a multipath zFCP LUN is now correctly recognized during the installation.
BZ#747604
The asynchronous TUR path checker caused multipathd to terminate unexpectedly due to memory corruption. This happened if multipathd attempted to delete a path while the asynchronous TUR checker was running on the path. The asynchronous TUR checker code has been removed, and multipathd no longer crashes on path removal.
Enhancements
BZ#636009
Multipath now supports up to 8000 device paths.
BZ#683616
To provide support for Asymmetric Logical Unit Access (ALUA), the RDAC checker has been modified to work better with devices in IOSHIP mode. The checker now sets the Task Aborted Status (TAS) bit to 1 if the TAS bit is set to 0 and changeable on a LUN (Logical Unit Number) discovery. The function now also reports PATH_UP for both the path groups in the RDAC storage in IOSHIP mode.
BZ#694602
To run multipath on IBM BladeCenter S-series with RAIDed Shared Storage Module (RSSM) demanded a manual multipath configuration to enable RSSM. Multipath now configures the server automatically.
BZ#699577
The text in the defaults multipaths devices sections of the multipath.conf man page has been improved to provide a better clarification.
BZ#713754
The rr_min_io_rq option has been added to the default, devices, and multipaths sections of the multipath.conf file. This option defines the number of I/O requests to route to a path before switching to the next path in the current path group. Note that the rr_min_io option is no longer used.
BZ#710478
UID, GID, and mode owner settings defined in /etc/multipath.conf for a multipath device are ignored. These access permissions are now set with the udev rules.
Users are advised to upgrade to these updated device-mapper-multipath packages, which fix these bugs and add these enhancements.
Updated device-mapper-multipath packages that fix a bug are now available for Red Hat Enterprise Linux 6.
The device-mapper-multipath packages provide tools to manage multipath devices by giving the dm-multipath kernel module instructions on what to do, as well as by managing the creation and removal of partitions for Device-Mapper devices.

Bug Fix

BZ#732384
When deleting a multipath device while checking a path, the multipathd daemon did not abort the path check. As a consequence, the daemon terminated when trying to access multipath device information. The problem has been fixed and the multipathd daemon now aborts the path check when deleting a multipath device.
All users of device-mapper-multipath are advised to upgrade to these updated packages, which fix this bug.

4.43. DeviceKit-power

Updated DeviceKit-power packages that add two enhancements are now available for Red Hat Enterprise Linux 6.
DeviceKit-power provides a daemon, API and command line tools for managing power devices attached to the system.

Enhancements

BZ#625880
To allow administrators easily disable the suspend and hibernate actions on the system, DeviceKit-power now checks the PolicyKit authorization before deciding whether an action can be completed.
BZ#727544
This update introduces a new sub-package DeviceKit-power-devel-docs, which contains developer's documentation for DeviceKit-power, so that it is now possible to install the DeviceKit-power-devel package on machines with multiple architectures without file conflicts.
All users are advised to upgrade to these updated DeviceKit-power packages, which add these enhancements.

4.44. dhcp

Updated dhcp packages that fix two security issues are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address.
Security Fixes
CVE-2011-2748, CVE-2011-2749
Two denial of service flaws were found in the way the dhcpd daemon handled certain incomplete request packets. A remote attacker could use these flaws to crash dhcpd via a specially-crafted request.
Users of DHCP should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing this update, all DHCP servers will be restarted automatically.
Updated dhcp packages that fix several bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.
The Dynamic Host Configuration Protocol (DHCP) is a protocol that allows individual devices on an IP network to get their own network configuration information, including an IP address, a subnet mask, and a broadcast address. DHCPv6 is the DHCP protocol that supports IPv6 networks.

Bug Fixes

BZ#694798
Previously, when multiple DHCP clients were launched at the same time to handle multiple virtual interfaces on the same network interface card (NIC), the clients used the same seed to choose when to renew their leases. Consequently, these virtual interfaces for some clients could have been removed over time. With this update, the dhclient utility uses the Process Identifier (PID) for seeding the random number generator, which fixes the bug.
BZ#694799
If a system was rebooted while a network switch was inoperative, the network connection would recover successfully. However, it was no longer configured to use DHCP even if the dhclient utility had been running in persistent mode. With this update, the dhclient-script file has been modified to refresh the ARP (Address Resolution Protocol) table and the routing table instead of bringing the interface down, which fixes the bug.
BZ#731990
If the system included network interfaces with no hardware address, the dhcpd scan could have experienced a segmentation fault when scanning such an interface. As a consequence, the dhcpd daemon unexpectedly terminated. To prevent this issue, dhcpd now tests a pointer which represents the hardware address of the interface for the NULL value. The dhcp daemon no longer crashes.
BZ#736999
Previously, all source files were compiled with the "-fpie" or "fPIE" flag. As a consequence, the libraries used by dhcp could not have been used to build Perl modules. To fix this problem, all respective dhcp Makefiles have been modified to compile libraries with the "-fpic" or "-fPIC" flag. The libraries used by dhcp are now built without the previous restrictions.
BZ#736194
Previously, both dhcp and dhclient packages included the dhcp-options(5) and dhcp-eval(5) man pages. As a consequence, a conflict could have occurred when any of these man pages were updated, because dhcp and dhclient packages could have been upgraded separately. To prevent the problem from occurring in future updates, shared files of dhcp and dhclient packages have been moved to the dhcp-common package that is required by both dhcp and dhclient as a dependency.

Enhancements

BZ#706974
A feature has been backported from dhcp version 4.2.0. This feature allows the DHCPv6 server to be configured to identify DHCPv6 clients in accordance with their link-layer address and their network hardware type. With this update, it is now possible to define a static IPv6 address for the DHCPv6 client with a known link-layer address.
BZ#693381
Previously, the dhcpd daemon ran as root. With this update, new "-user" and "-group" options can be used with dhcpd. These options allow dhcpd to change the effective user and group ID after it starts. The dhcpd and dhcpd6 services now run the dhcpd daemon with the "-user dhcpd -group dhcpd" parameters, which means that the dhcpd daemon runs as the dhcpd user and group instead root.
Users are advised to upgrade to these updated dhcp packages, which fixes these bugs and add these enhancements.

4.45. dmidecode

An updated dmidecode package that fixes one bug and adds one enhancement is now available for Red Hat Enterprise Linux 6.
The dmidecode package provides utilities for extracting x86 and Intel Itanium hardware information from the system BIOS or EFI (Extensible Firmware Interface), depending on the SMBIOS/DMI standard. This information typically includes system manufacturer, model name, serial number, BIOS version, and asset tag as well as other details, depending on the manufacturer. This often includes usage status for the CPU sockets, expansion slots such as AGP, PCI and ISA, among others, memory module slots, and many different kinds of I/O ports, such as serial, parallel and USB.
Prior to this update, the extended records for the DMI types Memory Device (DMI type 17) and Memory Array Mapped Address (DMI type 19) were missing from the dmidecode utility output. With this update, dmidecode has been upgraded to upstream version 2.11, which updates support for the SMBIOS specification to version 2.7.1, thus fixing this bug. Now, the dmidecode output contains the extended records for DMI type 17 and DMI type 19. (BZ#654833)
All users of dmidecode are advised to upgrade to this updated package, which fixes this bug and adds this enhancement.

4.46. dnsmasq

An updated dnsmasq package that addresses two bugs is now available for Red Hat Enterprise Linux 6.
Dnsmasq is a lightweight and easy-to-configure DNS forwarder and DHCP server.
Bug Fixes
BZ#584009
Three changes were made to /etc/init.d/dnsmasq, the dnsmasq startup script.
If dnsmasq was started or restarted by a non-privileged user, the startup script previously failed silently. With this update, the dnsmasq startup script now exits with a status code of 4 (user had insufficient privilege) and returns a "User has insufficient privilege" error to STD OUT when started or restarted by a non-privileged user.
A "force-reload" option was added: The "service force-reload dnsmasq" command now forces dnsmasq to reload. Previously, it did nothing.
If /etc/init.d/dnsmasq passed an invalid argument, previously the startup script exited with a status code of 1 (generic or unspecified error). With this update, the startup script now exits correctly, returning a status code of 2 (invalid or excess argument) in such a circumstance.
BZ#704073
If the virtual bridge interface (virbr0) was up and dnsmasq was started by default, dnsmasq could, in some circumstances, write a "DHCP packet received on eth(x) which has no address" message to /var/log/messages. Note: this message was not in error. The message was written if an actual interface (eg eth1) was up; did not have a configured IP address (eg was slaved to a logical bonded interface); and was in the same LAN as another host which generated a DHCP request. The message had little-to-no utility, however: it presented a warning where none was needed. With this update, this message is no longer written to /var/log/messages in these, and equivalent, circumstances.
All dnsmasq users should install this update which makes these changes.

4.47. dosfstools

An updated dosfstools package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
The dosfstools package contains a set of tools for creating and maintaining FAT-type file systems. It includes the mkdosfs and dosfsck utilities, which make and check MS-DOS FAT file systems on hard drives and floppy disks.

Bug Fixes

BZ#624596
Previously, when the dosfsck and the dosfslabel utilities were executed on the IBM System z architecture using a FAT32 file system, they terminated with this error message: "Logical sector size is zero". This was caused by unaligned fields which were first byte-wise copied. With this fix, the fields are not pre-copied any more, but are accessed the same way as on the i686 architecture.
BZ#677789
The fsck.vfat utility terminated due to buffer overflow. This occurred when checking a device with the corrupted VFAT file system if there were any chains of orphaned clusters. The name of the newly created file that contained these clusters was printed directly into the name field, which led to an out of boundary write. The name is now printed into the buffer and individual parts are then correctly copied into the appropriate field.
BZ#688128
The dosfslabel utility displayed an error message when labeling the FAT32 file system due to some of its internal structures being initialized incorrectly. The dosfslabel utility now reads the FAT file system first, which fixes the problem.
BZ#709266
The mkfs.vfat utility did not correctly detect device partitions on RAID devices. As a consequence, formatting failed with an error message. This was caused by an invalid mask for the statbuf.st_rdev variable. The mask has been fixed to be at least four bytes long and the problem no longer occurs.
All users of dosfstools are advised to upgrade to this updated package, which resolves these bugs.

4.48. dovecot

Updated dovecot packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
Dovecot is an IMAP server for Linux, UNIX, and similar operating systems, primarily written with security in mind.
Security Fix
CVE-2011-1929
A denial of service flaw was found in the way Dovecot handled NULL characters in certain header names. A mail message with specially-crafted headers could cause the Dovecot child process handling the target user's connection to crash, blocking them from downloading the message successfully and possibly leading to the corruption of their mailbox.
Users of dovecot are advised to upgrade to these updated packages, which contain a backported patch to resolve this issue. After installing the updated packages, the dovecot service will be restarted automatically.

4.49. doxygen

Updated doxygen packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Doxygen can generate an online class browser in HTML and/or a reference manual in LaTeX from a set of documented source files. The documentation is extracted directly from the sources.

Bug Fix

BZ#690076
Prior to this update, Doxygen required invalid BuildRequires on the qt-devel package. With this update, packages with BuildRequires dependencies on the qt-devel package have been fixed. Now, these packages explicitly require qt4-devel.
All users of Doxygen are advised to upgrade to these updated packages, which fix this bug.

4.50. dracut

Updated dracut packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The dracut packages include an event-driven initramfs generator infrastructure based on udev. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition.
Bug Fixes
BZ#659076
Previously, dracut incorrectly displayed that it loaded SELinux even if SELinux was disabled in the config file and "selinux=0" was not specified on the kernel command line. As a consequence, an error message could confuse the user when booting the system. With this update, the dracut utility is modified and the error message no longer appears.
BZ#696980
Due to an error in the dracut module script, the system could fail to find the root volume if a static IP address was specified. As a consequence, the system did not boot. With this update, the error is corrected, and the system is able to boot with a static IP address.
BZ#698160
When mounting the root device over the NFS (Network File System) protocol, the /var/lib/rpcbind directory created by initramfs was world-writable. The dracut tool has been modified to generate initramfs which now sets the ownership to the rpc user and the group.
BZ#698165
When auto-assembling an md RAID device, initramfs used an invalid parameter when calling the mdadm tool. This prevented the system from booting if the root device was on the RAID device. The invalid parameter has been removed and the system now boots properly.
BZ#698215
When auto-assembling an md RAID device, an error in the mdraid_start.sh script prevented the system from booting if the root device was on the RAID device. The error in the script has been fixed and the system now boots correctly.
BZ#701309
Prior to this update, the /var/lib/nfs/prc_pipefs partition could not be accessed on system boot. The problem occurred when booting the system with NFS set as the root partition with at least one separate /var partition. This was caused by initramfs mounting the /var partition over the existing rpc_pipefs partition. The initramfs file system now mounts entries in /etc/fstab.sys, which fixes the problem.
BZ#707609
The dm-mod and dm-crypt kernel modules were missing from the list of kernel modules, which are pre-loaded for the FIPS-140 check. These modules have been added to the list with this update.
BZ#712254
When loading SELinux from inside initramfs, the output of the SELinux commands could be garbled if the user used non-Latin locales. The initramfs file system has been modified to turn off localization for the SElinux commands, which results in readable messages.
BZ#737134
The QLogic qla4xxx iSCSI driver and the iSCSI (Internet Small Computer System Interface) transport layer now support iSCSI boot from Storage Area Network (SAN) using the iscsistart. With this update, dracut is modified to support these changes.
BZ#737593
If the user installed a system with rootfs on a RAID device where RAID members were encrypted, dracut failed to assemble the RAID device on reboot. As a consequence, the system did not boot. A patch has been applied to address this issue, and the RAID device is now assembled on every boot so that the system boots successfully.
BZ#741430
When applying SELinux labels for /dev in initramfs, the restorecon tool did not alter the MCS/MLS label only types. To fix this problem, the "-F" option has been added to all calls of restorecon.
BZ#742920
Prior to this update, the boot process timed out for network settings with DHCP involved. A patch has been applied to extend the timeout interval if DHCP is involved, which fixes the problem.
Enhancements
BZ#701864
This update adds support for iSCSI (Internet Small Computer System Interface) partial offload functionality for certain Broadcom network devices.
BZ#740487
This update adds the dracut-fips-aesni subpackage. Note that the package should be installed when using the aesni-intel module in FIPS mode.
BZ#723548
This update adds support for Logical Volume Management (LVM) mirror devices to serve as root devices. Additionally degraded mirrors are used after a certain timeout if the other half cannot be found at booting time.
BZ#729573
This update adds support for configuring an interface with automatic IPv6 and DHCP over IPv4 by using the "ip=[interface]:dhcp,auto6" command line parameter.
BZ#736094
With this update, the Broadcom FCoE (Fibre Channel over Ethernet) offload driver is now supported.
Users of dracut are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
Updated dracut packages that add an enhancement are now available for Red Hat Enterprise Linux 6.
The dracut package contains an event-driven initramfs generator infrastructure based around the udev device manager. The virtual file system, initramfs, is loaded together with the kernel at boot time and initializes the system, so it can read and boot from the root partition.

Enhancement

BZ#728549
The dm-mod and dm-crypt kernel modules were missing from the list of kernel modules which are pre-loaded for the FIPS-140 (Federal Information Processing Standards) check. With this update, these modules have been added to the list. This update also introduces the dracut-fips-aesni subpackage which should be installed if the aesni-intel module is used in FIPS mode.
Users of dracut are advised to upgrade to these updated packages, which add this enhancement.

4.51. dump

Updated dump packages that fix three bugs are now available for Red Hat Enterprise Linux 6.
The dump package contains both "dump" and "restore" commands. The "dump" command examines files in a file system, determines which ones need to be backed up, and copies those files to a specified disk, tape, or other storage medium. The "restore" command performs the inverse function of "dump"; it can restore a full backup of a file system. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.

Bug Fixes

BZ#702593
Prior to this update, the dump utility passed wrong arguments to the "clone(2)" system call. As a result, dump became unresponsive when executed on the S/390 or IBM System z architecture. This bug has been fixed in this update so that dump now passes correct arguments and no longer hangs.
BZ#691434
Under certain circumstances, the dump utility could have failed to detect holes in files correctly. When a user attempted to restore an erroneous backup using the "restore" command, an error message "Missing blocks at end of [path], assuming hole" could have been displayed. In such case, the backup could have not been restored properly. This bug has been fixed in this update so that dump now handles holes in files as expected.
BZ#658890
Prior to this update, the "dump -w" command did not recognize ext4 file systems as supported. With this update, the bug has been fixed so that "dump -w" now recognizes the ext4 file systems as supported.
All users of dump should upgrade to these updated packages, which fix these bugs.

4.52. e2fsprogs

Updated e2fsprogs packages that fix several bugs and add two enhancements are now available for Red Hat Enterprise Linux 6.
The e2fsprogs packages contain a number of utilities that create, check, modify, and correct inconsistencies in ext2, ext3, and ext4 file systems. This includes e2fsck (which repairs file system inconsistencies after an unclean shutdown), mke2fs (which initializes a partition to contain an empty file system), tune2fs (which modifies file system parameters), and most of the other core file system utilities.

Bug Fixes

BZ#676465
Running the "e2fsck" command on certain corrupted file systems failed to correct all errors during the first run. This occurred when a file had its xattr block cloned as a duplicate, but the block was later removed from the file because the file system did not contain the xattr feature. However, the block was not cleared from the block bitmaps. During the second run, e2fsck found the cloned xattr block as in use, but not owned by any file, and had to repair the block bitmaps. With this update, the processing of duplicate xattr blocks is skipped on non-xattr file systems. All problems are now discovered during the first run.
BZ#679931
On certain devices with very large physical sector size, the mke2fs utility set the block size to be as large as the size of the physical sector. In some cases, the size of the physical sector was larger than the page size. As a consequence, the file system could not be mounted and, in rare cases, the utility could even fail. With this update, the default block size is not set to be larger than the system's page size, even for large physical sector devices.
BZ#683906
Previously, multiple manual pages contained typos. These typos have been corrected with this update.
BZ#713475
This update modifies parameters of the "mke2fs" command to be consistent with the "discard" and "nodiscard" mount options for all system tools (like mount, fsck, or mkfs). The user is now also informed about the ongoing discard process.
BZ#730083
Previously, the libcomm_err libraries were built without the read-only relocation (RELRO) flag. Programs built against these libraries could be vulnerable to various attacks based on overwriting the ELF section of a program. To enhance the security, the e2fsprogs package is now provided with partial RELRO support.

Enhancements

BZ#679892
Previously, the tune2fs tool could not set "barrier=0" as the default option on the ext3 and ext4 file systems. With this update, users are now able to set this option when creating the file system, and do not have to maintain the option in the /etc/fstab file across all of the file systems and servers.
BZ#713468
Previously, raw e2image output files could be extremely large sparse files, which were difficult to copy, archive, and transport. This update adds support for exporting images in the qcow format. Images in this format are small and easy to manipulate.
Users are advised to upgrade to these updated e2fsprogs packages, which fix these bugs and add these enhancements.

4.53. ecryptfs-utils

Updated ecryptfs-utils packages that fix several security issues are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
eCryptfs is a stacked, cryptographic file system. It is transparent to the underlying file system and provides per-file granularity. eCryptfs is released as a Technology Preview for Red Hat Enterprise Linux 5 and 6.
The setuid mount.ecryptfs_private utility allows users to mount an eCryptfs file system. This utility can only be run by users in the "ecryptfs" group.
Security Fixes
CVE-2011-1831
A race condition flaw was found in the way mount.ecryptfs_private checked the permissions of a requested mount point when mounting an encrypted file system. A local attacker could possibly use this flaw to escalate their privileges by mounting over an arbitrary directory.
CVE-2011-1832
A race condition flaw in umount.ecryptfs_private could allow a local attacker to unmount an arbitrary file system.
CVE-2011-1834
It was found that mount.ecryptfs_private did not handle certain errors correctly when updating the mtab (mounted file systems table) file, allowing a local attacker to corrupt the mtab file and possibly unmount an arbitrary file system.
CVE-2011-1835
An insecure temporary file use flaw was found in the ecryptfs-setup-private script. A local attacker could use this script to insert their own key that will subsequently be used by a new user, possibly giving the attacker access to the user's encrypted data if existing file permissions allow access.
CVE-2011-1837
A race condition flaw in mount.ecryptfs_private could allow a local attacker to overwrite arbitrary files.
CVE-2011-3145
A race condition flaw in the way temporary files were accessed in mount.ecryptfs_private could allow a malicious, local user to make arbitrary modifications to the mtab file.
CVE-2011-1833
A race condition flaw was found in the way mount.ecryptfs_private checked the permissions of the directory to mount. A local attacker could use this flaw to mount (and then access) a directory they would otherwise not have access to.

Note

The fix for this issue is incomplete until a kernel-space change is made. Future Red Hat Enterprise Linux 5 and 6 kernel updates will correct this issue.
Red Hat would like to thank the Ubuntu Security Team for reporting these issues. The Ubuntu Security Team acknowledges Vasiliy Kulikov of Openwall and Dan Rosenberg as the original reporters of CVE-2011-1831, CVE-2011-1832, and CVE-2011-1833; Dan Rosenberg and Marc Deslauriers as the original reporters of CVE-2011-1834; Marc Deslauriers as the original reporter of CVE-2011-1835; and Vasiliy Kulikov of Openwall as the original reporter of CVE-2011-1837.
Users of ecryptfs-utils are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

4.54. esc

An updated esc package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
The esc package contains the Smart Card Manager GUI (Graphical User Interface), which allows the user to manage security smart cards. The primary function of the tool is to enroll smart cards, so that they can be used for common cryptographic operations, such as secure email and website access.

Bug Fixes

BZ#253077
If the user resized an ESC window and closed it, the window did not preserve its size when opening it again. If the user wanted the window to be larger, for example, to make it easier to read, the user had to resize the window every single time when it was opened again. A patch has been applied to address this issue and the previous window size is now restored when opening ESC.
BZ#682216
Previously, during the shut down sequence of the escd daemon, the daemon reported a failure of certain instances. ESC terminated unexpectedly with a segmentation fault as a consequence. This update modifies the daemon to exit quietly. As a result, ESC no longer terminates unexpectedly.
BZ#702683
The esc-prefs.js file contains helpful commented settings designed to assist the user in trying rarely used settings if the situation warrants. A number of these settings in the file contained typos. The typos have been corrected with this update.
BZ#704281
Previously, ESC could have terminated with a segmentation fault after the user had inserted a new smart card into the reader. This was due to a bug in the code which helped to bring a pop-up window to the foreground. The code is no longer needed to assure window focus, therefore it is no longer being executed. As a result, ESC no longer terminates in the scenario described.
All users of esc are advised to upgrade to this updated package, which fixes these bugs.

4.55. fakechroot

Updated fakechroot packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The fakechroot utility lets you run programs in a fake chroot environment without superuser privileges.

Bug Fix

BZ#730647
Due to multilib problems, the fakeroot command was only built on 64-bit architectures as a workaround, one which prevented the RPM package from being built on other architectures. This update resolves the multilib problems so that fakeroot now builds successfully on all architectures.
Users should upgrade to these updated packages, which resolve this issue.

4.56. fcoe-utils

An updated fcoe-utils package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The fcoe-utils package provides Fibre Channel over Ethernet (FCoE) utilities, such as the fcoeadm command line tool for configuring FCoE interfaces, and the fcoemon service to configure DCB Ethernet QOS filters.
The fcoe-utils package has been upgraded to upstream version 1.0.20, which provides a number of bug fixes and enhancements over the previous version. (BZ#695941)

Bug Fixes

BZ#639466
When stopping the fcoe service, the fcoe initscript did not properly clean up after itself as expected (did not remove FCoE devices, kill related processes and unload FCoE drivers). As a consequence, FCoE interfaces were not brought down and FCoE related threads were still running after the fcoe had been stopped. The "service fcoe stop" command is used to ensure safe after-update service restarts on FCoE dependent systems, therefore it cannot be used to remove FCoE devices and unload related kernel modules. Concerning this situation, the initscript has been modified to use the "stop force" command option to completely remove FCoE devices and unload related kernel modules. The fcoe service now should be stopped using the "service fcoe stop force" command.
BZ#732485
When removing a network interface with no fcoe port using the "fcoeadm -d" command, the fcoe port state machine set the removal operation incorrectly to wait without responding to fcoemon. This led to an internal error because fcoemon timed out waiting for the response. To resolve the problem, the code has been modified to return the code for no further action under these circumstances. The "fcoeadm -d" command now works for interfaces without the fcoe port as expected.
BZ#732485
The fcoemon service did not maintain any information about the relative state of a physical network interface and its dependent VLAN interfaces. As a consequence, the fcoe port of the VLAN interface could have been out of sync with the fcoe port of the physical device, resulting in undesired behavior, such as processing link events improperly. To fix this problem, a ready flag has been introduced. This flag is set to false when the physical port is disabled. Link events are now processed correctly for the vlan ports.
BZ#732485
When answering to an FCoE Initialization Protocol (FIP) VLAN Discovery request, some switches encapsulate FIP VLAN Discovery replies in a VLAN 0 tag which is wrapped around the packet's FIP frame header. Previously, when a packet containing such a reply reached a target network interface, some devices did not remove the VLAN tag before they started to process the FIP header. If the VLAN tag was not removed, the length of the processed header was larger than was expected, therefore the FIP parsing logic was not able to parse the FIP header correctly causing a loss of the packet. With this update, the parsing logic has been modified to skip over the VLAN header when necessary, and point to the correct start of the FIP header.
BZ#743689
The timeout for a kernel reply to fcoeadm operations was set to 5 seconds, which was not enough when processing an fcoeadm operation on a system with a large number of FCoE ports while a kernel was under heavy load. As a consequence, the "internal error" message was displayed even though the operation was finished successfully. To prevent this bug, the timeout for the kernel reply was increased to 30 seconds. No error message is now sent when an fcoeadm operation succeeds.
All users of fcoe-utils are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

4.57. fence-agents

An updated fence-agents package that fixes various bugs and adds several enhancements is now available for Red Hat Enterprise Linux 6.
Red Hat fence agents are a collection of scripts to handle remote power management for cluster devices. They allow failed or unreachable cluster nodes to be forcibly restarted and removed from the cluster.
The fence-agents package has been upgraded to upstream version 3.1.5, which provides a number of bug fixes and enhancements over the previous version. (BZ#707123)

Bug Fixes

BZ#731166
Due to a change in REST API, the fence_rhevm utility incorrectly reported status "UP" as "RUNNING". Consequently, the "fence_rhevm -o status" command always reported "OFF". This bug has been fixed, and fence_rhevm now reports status correctly.
BZ#718924
The fence_drac5 agent failed to clear its SSH sessions on exit as expected by firmware. Consequently, the fence agent appeared to be still connected to the device, and once the connection limit was reached, further logins to the device were not allowed. This bug has been fixed, and fence_drac5 now clears its SSH sessions properly.
BZ#693428
The "monitor" and "status" commands of the fence_ipmilan agent returned chassis status instead of the fence device status. As a result, when a server chassis was powered off, the fence_ipmilan agent exited with the incorrect result code "2" when passed one of these commands. Now, fence_ipmilan returns the correct result code "0" in the described scenario.
BZ#708052
When a blade server was removed from a blade chassis and was fenced via the fence_bladecenter utility with the "--missing-as-off" option enabled, and was scheduled with the "reboot" action, the fence failed. This bug has been fixed, and fence_bladecenter no longer returns an error if a blade server is missing.
BZ#718196
A list operation on fence_drac5 agents resulted in unexpected termination of fence agents. A patch has been provided to address this issue, and fence_drac5 agents now work correctly in the described scenario.
BZ#718207
When the pyOpenSSL package was not present in the system, when an error occurred, the fence_ilo agent terminated with a generic error message, making it difficult to debug the problem. Now, fence_ilo reports that a dependent package is missing in the described scenario, thus fixing this bug.
BZ#732372
The verbose mode of the fence_ipmilan agent exposed user passwords when the whole command was logged by an IPMI tool. Now, the fence_ipmilan output has been changed, and passwords remain undisclosed in the described scenario.
BZ#738384
During simultaneous unfencing operations performed via the fence_scsi agent, all nodes launched their reservation commands at the same time. Consequently, some of the commands failed. Now, fence_scsi retries to unfence a node until its reservation command succeeds.
BZ#734429
A null dereference was discovered in the fence_kdump agent, when the strchr() function returned the NULL value. With this update, the dereference has been fixed in the code and no longer occurs.

Enhancements

BZ#624673
With this update, the new fence_vmware_soap() function has been provided to enable fencing of VMware guests in ESX environments.
BZ#461948
The fence_kdump utility has been updated to integrate fencing with the kernel dump environment.
BZ#698365
With this update, the RelaxNG schema generation for fence-agents has been updated with the rha:description and rha:name attributes in its output to fence attribute group elements.
BZ#726571
The fence_ipmilan agent has been updated to support the -L option of the ipmilan daemon, thus supporting fencing with user session privileges level.
Users of fence-agents are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

4.58. fence-virt

Updated fence-virt packages that fix two bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The fence-virt packages provide a fencing agent for virtual machines as well as a host agent which processes fencing requests.

Bug Fixes

BZ#719645
Prior to this update, the domain parameter was missing from the metadata. As a consequence, existing configurations utilizing the domain parameter did not function correctly when fencing. This update adds the domain parameter for compatibility. Now, existing configurations work as expected.
BZ#720767
Prior to this update, hash mismatches falsely returned successes for fencing. As a consequence, data corruption could occur in live-hang scenarios. This update corrects the hash handling of mismatches. Now, no more false successes are returned and the data integrity is preserved.

Enhancement

BZ#691200
With this update, the libvirt-qpid plugin now operates using QMF version 2.
All users of fence-virt are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

4.59. file

Updated file packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The file command is used to identify a particular file according to the type of data contained in the file.
[Updated 7 September 2011] This update fixes a bug in which the file utility did not parse ELF (Executable and Linkable Format) binary files correctly. If an entry in the program header table contained a file offset beyond the end of file, dynamically linked files were reported as being linked statically. The file utility now recognizes files in the described scenario correctly. (BZ#730336)

Bug Fixes

BZ#676045, BZ#712992, BZ#712988
Prior to this update, the file utility could have been unable to recognize RPM files for certain supported architectures. This update improves the file type recognition, and the RPM files for all supported architectures are now correctly identified as expected.
BZ#688700
Prior to this update, the file utility did not correctly recognized the IBM System z kernel images. This problem has been corrected so that the IBM System z kernel images are now correctly recognized as expected.
BZ#692098
Prior to this update, the file utility attempted to show information related to core dumps for binary files that were not core dumps. This undesired behavior has been fixed in this update so that information related to core dumps is showed only for core dumps and not for the binary files which are not core dumps.
BZ#675691
Prior to this update, file patterns for LaTeX checked only the first 400 bytes of a file to determine the pattern type. This caused an incorrect pattern type recognition as some files could have contained a larger number of comments at the beginning of the file. Furthermore, file patterns which matched a Python script were tried before the LaTeX patterns and this undesired behavior could have caused an incorrect pattern type recognition as LaTeX files could have included a source code written in Python. With this update, the aforementioned problems have been fixed by increasing the number of first bytes checked for a LaTeX file to 4096 bytes, and by trying the LaTeX patterns before the Python patterns.
BZ#690801
Prior to this update, there were several spelling mistakes contained in the magic(5) manual page. This update corrects the spelling mistakes in the respective manual page.
BZ#716665
Prior to this update, the file utility treated MP3 files as text files, and therefore was unable to recognize the MP3 files. This undesired behavior has been fixed in this update, and the file utility now treats the MP3 files as binary files and is able to properly recognize them.
All users of file are advised to upgrade to these updated packages, which fix these bugs.

4.60. filesystem

An updated filesystem package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The filesystem package is one of the basic packages that is installed on a Red Hat Enterprise Linux system. The filesystem package contains the basic directory layout for the Linux operating system, including the correct permissions for directories.

Bug Fix

BZ#620063
Prior to this update, certain locale subdirectories in the /usr/share/locale/ directory did not have any owner set. With this update, this bug has been fixed so that the filesystem package now owns the subdirectories of the following locales: bg_BG (Bulgarian), en_NZ (New Zealand English), fi_FI (Finnish), gl_ES (Galician), lv_LV (Latvian), ms_MY (Malaysian), sr_RS (Serbian), en@shaw (Shavian), zh_CN.GB2312 (Chinese Simplified), sr@ijekavian (Serbian Jekavian), and sr@ijekavianlatin (Serbian Jekavian Latin).
All users of filesystem are advised to upgrade to this updated package, which fixes this bug.

4.61. fipscheck

Updated fipscheck packages that add one enhancement are now available for Red Hat Enterprise Linux 6.

All users who use fuse file systems in their environment are advised to upgrade to this updated fuse package, which fixes this bug.

4.68. gcc

Updated gcc packages that fix various bugs and add three enhancements are now available for Red Hat Enterprise Linux 6.
The gcc packages include C, C++, Java, Fortran, Objective C, Objective C++, and Ada 95 GNU compilers, along with related support libraries.

Bug Fixes

BZ#696352
The previous version of GCC incorrectly assumed that processors based on the AMD's multi-core architecture code named Bulldozer support the 3DNow! instruction set. This update adapts the underlying source code to make sure that GCC no longer uses the 3DNow! instructions on these processors.
BZ#705764
On the PowerPC architecture, GCC previously passed the V2DImode vector parameters using the stack and returned them in integer registers, which does not comply with the Application Binary Interface (ABI). This update corrects this error so that GCC now passes these parameters using the AltiVec parameter registers and returns them via the AltiVec return value register.
BZ#721376
Previously, GCC did not flush all pending register saves in a Frame Description Entry (FDE) before inline assembly instructions. This may have led to various problems when the inline assembly code modified those registers. With this update, GCC has been adapted to flush pending register saves in FDE before inline assembly instructions, resolving this issue.
BZ#732802
Prior to this update, the gcov test coverage utility sometimes incorrectly counted even opening brackets, which caused it to produce inaccurate statistics. This update applies a patch that corrects this error so that gcov ignores such brackets, as expected.
BZ#732807
When processing source code that extensively used overloading (that is, with hundreds or more overloads of the same function or method), the previous version of the C++ front end consumed a large amount of memory. This negatively affected the overall compile time and the amount of used system resources. With this update, the C++ front end has been optimized to use less resources in this scenario.

Enhancements

BZ#696145
This update adds support for new "-mfsgsbase", "-mf16c", and "-mrdrnd" command line options, as well as corresponding intrinsics to the immintrin.h header file. This allows for reading FS and GS base registers, retrieving random data from the random data generator, and converting between floating point and half-precision floating-point types.
BZ#696370
GCC now supports AMD's next generation processors. These processors can now be specified on the command line via the "-march=" and "-mtune=" command line options.
BZ#696495
GCC now supports Intel's next generation processor instrinsics and instructions for reading the hardware random number generator.
All users of gcc are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

4.69. gdb

Updated gdb packages that fix multiple bugs and add three enhancements are now available for Red Hat Enterprise Linux 6.
The GNU Debugger (GDB) allows users to debug programs written in C, C++, and other languages by executing them in a controlled fashion and then printing out their data.

Bug Fixes

BZ#669432
Prior to this update, GDB could stop on error when trying to access the libpthread shared library before the library was relocated. Fixed GDB lets the relocations to be resolved first, making such program debuggable.
BZ#669434
The Intel Fortran Compiler records certain debug info symbols in uppercase but the gfortran compiler writes case-insensitive symbols in lowercase. As a result, GDB could terminate unexpectedly when accessing uppercase characters in the debug information from the Intel Fortran Compiler. With this update, GDB properly implements case insensitivity and ignores the symbols case in the symbol files.
BZ#692386
When the user selected the "-statistics" option with a negative number as a result, GDB printed the minus sign twice. This has been fixed and GDB now displays negative numbers with one minus sign only.
BZ#697900
On the PowerPC and the IBM System z architectures, GDB displayed only LWP (light-weight process) identifiers which matched the Linux TID (Thread Identifier) values for the threads found in the core file. GDB has been fixed to initialize the libthread_db threads debugging library when accessing the core file. GDB now correctly displays the pthread_t identifier in addition to the LWP identifier on the aforementioned architectures.
BZ#702427
Structure field offsets above 65535 described by the DWARF DW_AT_data_member_location attribute were improperly interpreted as a 0 value. GDB has been modified and can now handle also large structures and their fields.
BZ#704010
The difference between the very closely related "ptype" and "whatis" commands was not clearly defined in the gdb info manual. Detailed differences between these commands have been described in the manual.
BZ#712117
Prior to this update, the "info sources" subcommand printed only relative paths to the source files. GDB has been modified to correctly display the full path name to the source file.
BZ#730475
Modifying a string in the executable using the "-write" command line option could fail with an error if the executable was not running. With this update, GDB can modify executables even before they are started.

Enhancements

BZ#696890
With this update, Float16 instructions on future Intel processors are now supported.
BZ#698001
Debugged programs can open many shared libraries on demand at runtime using the dlopen() function. Prior to this update, tracking shared libraries that were in use by the debugged program could lead to overhead. The debugging performance of GDB has been improved: the overhead is now lower if applications load many objects.
BZ#718141
Prior to this update, GDB did not handle DWARF 4 .debug_types data correctly. Now, GDB can correctly process data in the DWARF 4 format.
All GDB users are advised to upgrade to these updated gdb packages, which fix these bugs and add these enhancements.

4.70. gdm

Updated gdm packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
The GNOME Display Manager (GDM) provides the graphical login screen, shown shortly after boot up, log out, and when user-switching.

Bug Fixes

BZ#661618
GDM did not properly queue up multiple authentication messages so that messages could quickly be overwritten by newer messages. The queueing mechanism has been modified, and this problem no longer occurs.
BZ#628462
If a Russian keyboard layout was chosen during system installation, the login screen was configured to use Russian input for user names and passwords by default. However, GDM did not provide any visible way to switch between keyboard layouts, and pressing Left Shift and Right Shift keys did not cause the input to change to ASCII mode in GDM. Consequently, users were not able to log in to the system. With this update, GDM allows users to switch keyboard layout properly using the keyboard layout indicator, and users can now log in as expected.
BZ#723515
GDM did not properly release file descriptors used with XDMCP indirect queries. As a consequence, the number of file descriptors used by GDM increased with every XDMCP chooser restart, which, in some cases, led to memory exhaustion and a GDM crash. The underlying GDM code has been modified to manage file descriptors properly, and the problem no longer occurs in this scenario.
BZ#670619
In multi-monitor setups, GDM always displayed the login window on the screen that was determined as active by the mouse pointer position. This behavior caused unpredictable login window placement in dual screen setups when using the NVIDIA's TwinView Dual-Display Architecture because the mouse pointer initially appeared exactly between the monitors outside of the visible screen. GDM now uses new logic to ensure that the initial placement of the mouse pointer and the login window are consistently on one screen.
BZ#645453
The GDM simple greeter login window displayed "Suspend", "Restart" and "Shut Down" buttons even though the buttons were disabled in GDM configuration and the PolicyKit toolkit disallowed any stop, restart, suspend actions on the system. With this update, GDM logic responsible for setting up the greeter login window has been modified and these buttons are no longer displayed under these circumstances
BZ#622561
When authenticating to a system and the fingerprint authentication method was enabled, but no fingerprint reader was attached to the machine, GDM erroneously displayed authentication method buttons for a brief moment. With this update, GDM displays authentication method buttons only if the authentication method is enabled and a reading device is connected.
BZ#708430
GDM did not properly handle its message queue. Therefore, when resetting a password on user login, GDM displayed an error message from a previous unsuccessful attempt. The queueing mechanism has been modified, and this problem no longer occurs.
BZ#688158
When logging into a system using LDAP authentication, GDM did not properly handle LDAP usernames containing backslash characters. As a consequence, such usernames were not recognized and users were not able to log in even though they provided valid credentials. With this update, GDM now handles usernames with backslash characters correctly and users can log in as expected.
All users of gdm are advised to upgrade to these updated packages, which fix these bugs.

4.71. ghostscript

Updated ghostscript packages that fix a bug are now available for Red Hat Enterprise Linux 6.
The Ghostscript suite provides a PostScript interpreter, a set of C procedures (the Ghostscript library, which implements the graphics capabilities in the PostScript language), and an interpreter for PDF files. Ghostscript translates PostScript code into many common, bitmapped formats, like those understood by most printers and displays. This enables users to display PostScript files and print them on non-PostScript printers.

Bug Fix

BZ#710651
Previously, the default paper size was selected in portrait orientation when printing documents in landscape orientation. Consequently, the output was printed in portrait orientation and the content was cropped on the right side. With this update, if the paper size matches in landscape mode, that paper size is selected and the landscape orientation is selected for printing.
All users of ghostscript are advised to upgrade to these updated packages, which fix this bug.

4.72. gimp

Updated gimp packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

CVE-2010-4540, CVE-2010-4541, CVE-2010-4542
A stack-based buffer overflow flaw was found in the GIMP's Lightning, Sphere Designer, and Gfig image filters. An attacker could create a specially-crafted Lightning, Sphere Designer, or Gfig filter configuration file that, when opened, could cause the relevant plug-in to crash or, potentially, execute arbitrary code with the privileges of the user running the GIMP.
Users of the GIMP are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The GIMP must be restarted for the update to take effect.

4.73. glibc

Updated glibc packages that fix two security issues, numerous bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly.
Security Fixes
CVE-2009-5064
A flaw was found in the way the ldd utility identified dynamically linked libraries. If an attacker could trick a user into running ldd on a malicious binary, it could result in arbitrary code execution with the privileges of the user running ldd.
CVE-2011-1089
It was found that the glibc addmntent() function, used by various mount helper utilities, did not handle certain errors correctly when updating the mtab (mounted file systems table) file. If such utilities had the setuid bit set, a local attacker could use this flaw to corrupt the mtab file.
Red Hat would like to thank Dan Rosenberg for reporting the CVE-2011-1089 issue.
Bug Fixes
BZ#676467
The installation of the glibc-debuginfo.i686 and glibc-debuginfo.x86_64 packages failed with a transaction check error due to a conflict between the packages. This update adds the glibc-debuginfo-common package that contains debuginfo data that are common for all platforms. The package depends on the glibc-debuginfo package and the user can now install debuginfo packages for different platforms on a single machine.
BZ#676591
When a process corrupted its heap, the malloc() function could enter a deadlock while creating an error message string. As a result, the process could become unresponsive. With this update, the process uses the mmap() function to allocate memory for the error message instead of the malloc() function. The malloc() deadlock therefore no longer occurs and the process with a corrupted heap now aborts gracefully.
BZ#692838
India has adopted a new symbol for the Indian rupee leaving the currency symbol for its Unicode U20B9 outdated. The rupee symbol has been updated for all Indian locales.
BZ#694386
The strncmp() function, which compares characters of two strings, optimized for IBM POWER4 and POWER7 architectures could return incorrect data. This happened because the function accessed the data past the zero byte (\0) of the string under certain circumstances. With this update, the function has been modified to access the string data only until the zero byte and returns correct data.
BZ#699724
The crypt() function could cause a memory leak if used with a more complex salt. The leak arose when the underlying NSS library attempted to call the dlopen() function from libnspr4.so with the RTLD_NOLOAD flag. With this update, the dlopen() with the RTLD_NOLOAD flag has been fixed and the memory leak no longer occurs.
BZ#700507
On startup, the nscd daemon logged the following error into the log file if SELinux was active:
rhel61 nscd: Can't send to audit system: USER_AVC avc:  netlink
poll: error 4#012: exe="?" sauid=28 hostname=? addr=? terminal=?
This happened because glibc failed to preserve the respective capabilities on UID change in the AVC thread. With this update, the AVC thread preservers the respective capabilities after the nscd startup.
BZ#703481, BZ#703480
When a host was temporarily unavailable, the nscd daemon cached an error, which did not signalize that the problem was only transient, and the request failed. With this update, the daemon caches a value signalizing that the unavailability is temporary and retries to obtain new data after a set time limit.
BZ#705465
When a module did not provide its own method for retrieving a user list of supplemental group memberships, the libc library's default method was used instead and all groups known to the module were examined to acquire the information. Consequently, applications which attempted to retrieve the information from multiple threads simultaneously, interfered with each other and received an incomplete result set. This update provides a module-specific method which prevents this interference.
BZ#706903
On machines using the Network Information Service (NIS), the getpwuid() function failed to resolve UIDs to user names when using the passwd utility in the compat mode with a big netgroup. This occurred because glibc was compiled without the -DUSE_BINDINGDIR=1 option. With this update, glibc has been compiled correctly and getpwuid() function works as expected.
BZ#711927
A debugger could have been presented with an inconsistent state after loading a library. This happened because the ld-linux program did not relocate the library before calling the debugger. With this update, the library is relocated prior to the calling of the debugger and the library is accessed successfully.
BZ#714823
The getaddrinfo() function internally uses the simpler gethostbyaddr() functions. In some cases, this could result in incorrect name canonicalization. With this update, the code has been modified and the getaddrinfo() function uses the gethostbyaddr() functions only when appropriate.
BZ#718057
The getpwent() lookups to LDAP (Lightweight Directory Access Protocol) did not return any netgroup users if the NIS (Network Information Service) domain for individual users was not defined in /etc/passwd. This happened when the nss_compat mode was set as the mode was primarily intended for use with NIS. With this update, getpwent returns LDAP netgroup users even if the users have no NIS domain defined.
BZ#730379
The libresolv library is now compiled with the stack protector enabled.
BZ#731042
The pthread_create() function failed to cancel a thread properly if setting of the real time policy failed. This occurred the because __pthread_enable_asynccancel() function as a non-leaf function did not align the stack on the 16-byte boundary as required by AMD64 ABI (Application Binary Interface). With this update, the stack alignment is preserved accros functions.
BZ#736346
When calling the setgroups function after creating threads, glibc did not cross-thread signal and supplementary group IDs were set only for the calling thread. With this update, the cross-thread signaling in the function has been introduced and supplementary group IDs are set on all involved threads as expected.
BZ#737778
The setlocale() function could fail. This happened because parameter values were parsed in the set locale. With this update, the parsing is locale-independent.
BZ#738665
A write barrier was missing in the implementation of addition to linked list of threads. This could result in the list corruption after several threads called the fork() function at the same time. The barrier has been added and the problem no longer occurs.
BZ#739184
Statically-linked binaries that call the gethostbyname() function terminated because of division by zero. This happened because the getpagesize() function required the dl_pagesize field in the dynamic linker's read-only state to be set. However, the field was not initialized when a statically linked binary loaded the dynamic linker. With this update, the getpagesize() function no longer requires a non-zero value in the dl_pagesize field and falls back to querying the value through the syscall() function if the field value is not set.
Enhancements
BZ#712248
For some queries, the pathconf() and fpathconf() functions need details about each filesystem type: mapping of its superblock magic number to various filesystem properties that cannot be queried from the kernel. This update adds support for the Lustre file system to pathconf and fpathconf.
BZ#695595
The glibc package now provides functions optimized for the Intel 6 series and Intel Xeon 5600 processors.
BZ#695963
The glibc package now supports SSE2 (Streaming SIMD Extensions 2) instructions on the strlen() function for the AMD FX processors.
BZ#711987
This update adds the f_flags field to support the statvfs output received from kernel.
BZ#738763
The Linux kernel supports the UDP IP_MULTICAST_ALL socket option, which provides the ability to turn off IP Multicast multiplexing. This update adds the option to glibc.
Users are advised to upgrade to these updated glibc packages, which contain backported patches to resolve these issues and add these enhancements.
Updated glibc packages that resolve several issues are now available for Red Hat Enterprise Linux 6.
The glibc packages contain the standard C and the standard math libraries. These libraries are used by multiple programs on the system, and without these libraries, the Linux system cannot function properly.

Bug Fixes

BZ#712125
Under certain circumstances, a threaded process could have been granted incomplete group membership of the user which was running the process. This was caused by glibc using its default method for group membership determination, which led to a situation in which multiple threads interfered with each other while attempting to retrieve information simultaneously. Due to the nature of the group membership determination method used, each thread ended up with a different subset of the entire result set. With this update, the group membership determination method has been modified to precede this interference.
BZ#712407
When a process corrupted its heap, the malloc() function could have entered a deadlock situation while building up an error message string. This caused the process unresponsive. With this update, the code has been modified to use the mmap() function to allocate memory for the error message. This workaround ensures that the malloc() deadlock no longer occurs when allocating memory for an error message when the corrupted process heap is detected, and such a process is now normally aborted.
BZ#712411
Prior to this update, the Name Service Caching Daemon (nscd) did not clear the host cache effectively when repopulating its values. The code has been modified to schedule nscd cache pruning more accurately.
BZ#715387
Previously, nscd did not take into consideration time-to-live (TTL) parameters for the DNS records it was caching. With this update, the code has been modified so that nscd now respects TTL parameters when it answers requests for DNS records.
All users of glibc are advised to upgrade to these updated packages, which resolve these issues.

4.74. gnome-screensaver

An updated gnome-screensaver package that fixes various bugs and adds one enhancement is now available for Red Hat Enterprise Linux 6.
The gnome-screensaver package contains the GNOME project's official screen saver program. It is designed for improved integration with the GNOME desktop, including themeability, language support, and Human Interface Guidelines (HIG) compliance. It also provides screen-locking and fast user-switching from a locked screen.

Bug Fixes

BZ#648850
When the user locked the screen and the X Window System did not support the X Resize, Rotate (XRandR) or XF86VM gamma fade extensions, then the gnome-screensaver utility terminated with a segmentation fault. With this update, additional checks are made before calling the fade_setup() function, and gnome-screensaver no longer terminates.
BZ#697892
Prior to this update, the Unlock dialog box arbitrarily changed between the monitors in dual head setups, based on the position of the mouse pointer. The Unlock dialog box is now placed on a consistent monitor instead of where the mouse is located.
BZ#719023
Previously, when docking a laptop and using an external monitor, parts of the background got cut off due to incorrect logic for determining monitor dimensions. With this update, the source code is modified and the login screen is now displayed correctly.
BZ#740892
Previously, in rare cases, the screen saver entered a deadlock if monitors were removed during the fade up. The screen was locked as a consequence. This update modifies gnome-screensaver so that the screen saver responds as expected.

Enhancement

BZ#677580
Previously, there was no indicator of the keyboard layout when the screen was locked. Users who used more than one layout did not know which layout was active. Consequently, users could be forced to type the password several times. This update adds the missing keyboard layout indicator.
All users of gnome-screensaver are advised to upgrade to this updated package, which fixes these bugs and adds this enhancement.

4.75. gnome-session

Updated gnome-session packages that fix a bug and add an enhancement are now available for Red Hat Enterprise Linux 6.
The gnome-session package manages the GNOME desktop session. It starts up the other core components of GNOME and handles logout and saving of the session.

Bug Fix

BZ#664516
Prior to this update, the gnome-session utility may have improperly saved desktop sessions. As a consequence, when logging in, the running applications were incorrectly collapsed from multiple workspaces into the first workspace and their initial position was not restored. This has been fixed: applications are now restored in their original workspaces and correctly positionally placed.
Enhancement
BZ#622849
Prior to this update, users were not able to manage multiple custom GNOME sessions while being logged in. Now, multiple sessions can be managed under the Options tab of System -> Preferences -> Startup Applications.

Users of gnome-system-monitor are advised to upgrade to this updated package, which adds this enhancement.

4.77. gnome-terminal

An updated gnome-terminal package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The gnome-terminal package contains a terminal emulator for GNOME. It supports translucent backgrounds, opening multiple terminals in a single window (tabs) and clickable URLs.

Bug Fix

BZ#655132
Previously, the regular expression used to find URLs in the text was missing a colon character. As a consequence, the URL containing a colon was not interpreted correctly. With this update, a colon character has been added to the regular expression so that the URL is now properly interpreted.
All gnome-terminal users are advised to upgrade to this updated package, which fixes this bug.

4.78. gpm

Updated gpm packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The gpm packages contain a program handling mouse services on a system console device.

Bug Fix

BZ#684920
Prior to this update, it was not possible to build the gpm packages on the supported platforms if the emacs package was installed. This problem has been resolved with this update and no longer occurs.
All users of gpm are advised to upgrade to these updated packages, which fix this bug.

4.79. gpxe

Updated gpxe packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The gpxe packages provide an open source Preboot Execution Environment (PXE) implementation and bootloader. gPXE also supports additional protocols such as DNS, HTTP, iSCSI and ATA over Ethernet.

Bug Fix

BZ#743893
Prior to this update, PXE failed to boot a virtual machine which used the virtio network interface card (NIC). An upstream patch, which incorporates the latest upstream gPXE paravirtualized network adapter (virtio-net) driver and removes the legacy Etherboot virtio-net driver, has been applied to fix this problem. Now, PXE can successfully boot virtual machines that use virtio NIC.
All users of gpxe are advised to upgrade to these updated packages, which fix this bug.

4.80. graphviz

Updated graphviz packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
Graphviz is graph visualization software used to represent structural information as diagrams, abstract graphs or networks.

Bug Fixes

BZ#624658
Several links in the Graphviz Documentation Index file led to nonexistent or incorrectly named files. This update fixes these links so that their targets resolve correctly.
BZ#624690
The graphviz test suite was disabled on the PowerPC, 64-bit PowerPC and SPARC64 architectures due to unexpected terminations with segmentation faults. The test code used in the test suite did not set the TextLayout plugin correctly, which led to the crash of the test suite. This has been fixed and the test suite passes on all architectures.
BZ#640247
Prior to this update, the About dialog box displayed "<unknown>" instead of the real name of the DotEdit utility. This has been fixed and the name is now displayed correctly.
BZ#679715
When using the graphviz utility with PHP, the gv.so module did not load and displayed the following error message:
/usr/lib64/php/modules/gv.so' - /usr/lib64/php/modules/gv.so: undefined symbol: zend_error_noreturn in Unknown on line 0
This was caused by the SWIG tool which used the zend_error_noreturn() function to build the PHP module. SWIG has been modified and the bug no longer occurs.
All users of graphviz are advised to upgrade to these updated packages, which fix these bugs.

4.81. grub

An updated grub package that fixes three bugs and adds two enhancements is now available for Red Hat Enterprise Linux 6.
The GRUB utility is responsible for booting the operating system kernel.

Bug Fixes

BZ#677468
Due to an error in the underlying source code, previous versions of GRUB may have failed to boot in Unified Extensible Firmware Interface (UEFI) mode. This happened, because GRUB was making UEFI calls without aligning the stack pointer to a 16-byte boundary. With this update, a patch has been applied to correct this error, and GRUB now boots in UEFI mode as expected.
BZ#736833
Prior to this update, an attempt to install GRUB on a CCISS device may have caused the grub-install utility to report the following error:
expr: non-numeric argument
When this happened, grub-install failed to install GRUB on this device, but incorrectly reported success and returned a zero exit status. This update applies a patch that ensures that GRUB can now be successfully installed on such devices.
BZ#746106
When looking for its configuration file, the previous versions of GRUB did not respect vendor-specific EFI device path. With this update, the underlying source code has been adapted to use the vendor-specific EFI-device path as expected.

Enhancements

BZ#629408
Prior to this update, the GRUB boot loader was unable to boot from boot drives that were larger than 2.2 TB. This update adds support for such devices on UEFI systems.
BZ#671355
On BIOS-based systems, previous versions of GRUB were only able to boot from first eight disk drives. This update allows GRUB to boot from up to 128 disk drives on these systems.

4.83. httpd

Updated httpd packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The Apache HTTP Server is a popular web server.
Security Fix
CVE-2011-3192
A flaw was found in the way the Apache HTTP Server handled Range HTTP headers. A remote attacker could use this flaw to cause httpd to use an excessive amount of memory and CPU time via HTTP requests with a specially-crafted Range header.
All httpd users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
Updated httpd packages that fix two security issues and one bug are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The Apache HTTP Server is a popular web server.
Security Fixes
CVE-2011-3368
It was discovered that the Apache HTTP Server did not properly validate the request URI for proxied requests. In certain configurations, if a reverse proxy used the ProxyPassMatch directive, or if it used the RewriteRule directive with the proxy flag, a remote attacker could make the proxy connect to an arbitrary server, possibly disclosing sensitive information from internal web servers not directly accessible to the attacker.
CVE-2011-3348
It was discovered that mod_proxy_ajp incorrectly returned an "Internal Server Error" response when processing certain malformed HTTP requests, which caused the back-end server to be marked as failed in configurations where mod_proxy was used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period or until all back-end servers were marked as failed.
Red Hat would like to thank Context Information Security for reporting the CVE-2011-3368 issue.

Bug Fix

BZ#736592
The fix for CVE-2011-3192 provided by the RHSA-2011:1245 update introduced regressions in the way httpd handled certain Range HTTP header values. This update corrects those regressions.
All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.
Updated httpd packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The Apache HTTP Server is a popular web server.

Bug Fixes

BZ#694939
The Apache module "mod_proxy" implements a proxy or gateway for the Apache web server. The "ProxyErrorOverride On" option did not work if used with "mod_proxy_ajp", the AJP support module for mod_proxy. Consequently when accessing a 404 URL in the "/static" context, which was proxied with AJP, the 404 page from the proxy was displayed rather than the 404 page from Apache itself. This update corrects the code and accessing 404 URLs now works as intended, via Apache, as defined in "ErrorDocument".
BZ#700074
When a backend server sends data via SSL, and is using chunked transfer encoding, the backend splits the chunk between two different SSL blocks. Prior to this update, when transferring data via SSL through a reverse proxy implemented with Apache, "mod_proxy", and "mod_ssl", the end of the first SSL block was sometimes lost and the length of the next chunk was thus invalid. Consequently, files were sometimes corrupted during transfer via SSL. This updates implements a backported fix to this problem and the error no longer occurs.
BZ#700075
The "FilterProvider" directive of the "mod_filter" module was unable to match against non-standard HTTP response headers. Consequently, output content data was not filtered or processed as expected by httpd in certain configurations. With this update, a backported patch has been applied to address this issue, and the FilterProvider directive is now able to match against non-standard HTTP response headers as expected.
BZ#700393
In situations where httpd could not allocate memory, httpd sometimes terminated unexpectedly with a segmentation fault rather than terminating the process with an error message. With this update, a patch has been applied to correct this issue and httpd no longer crashes in the scenario described.
BZ#714704
Server Name Indication (SNI) sends the name of the virtual domain as part of the TLS negotiation. Prior to this enhancement, if a client sent the wrong SNI data the client would be rejected. With this update, in configurations where SNI is not required, "mod_ssl" can ignore the SNI hostname "hint".
BZ#720980
Prior to this update, httpd terminated unexpectedly on startup with a segmentation fault when proxy client certificates were shared across multiple virtual hosts (using the SSLProxyMachineCertificateFile directive). With this update a patch has been applied and httpd no longer crashes in the scenario described.
BZ#729585
When the "SSLCryptoDevice" config variable in "ssl.conf" was set to an unknown or invalid value, the httpd daemon would terminate unexpectedly with a segmentation fault at startup. With this update the code has been corrected, httpd no longer crashes, and httpd will issue an appropriate error message in this scenario.
BZ#737960
If using mod_proxy_ftp, an httpd process could terminated unexpectedly with a segmentation fault when tests were made on an IPv6 localhost enabled machine. This update implements improvements to the code and the mod_proxy_ftp process no longer crashes in the scenario described.
BZ#740242
When using the "mod_cache" module, by default, the "CacheMaxExpire" directive is only applied to responses which do not specify their expiry date. Previously, it was not possible to limit the maximum expiry time for all resources. This update applies a patch which adapts the mod_cache module to provide support for "hard" as a second argument of the CacheMaxExpire directive, allowing a maximum expiry time to be enforced for all resources.
BZ#676634
The "mod_reqtimeout" module, when enabled, allows fine-grained timeouts to be applied during request parsing. The mod_reqtimeout module has been backported from upstream in this update.
All users of httpd are advised to upgrade to these updated packages, which fix these bugs.

4.85. ibus

Updated ibus packages that resolve an issue are now available for Red Hat Enterprise Linux 6.
The Intelligent Input Bus for Linux OS (IBus) is an input framework for Linux OS.

Bug Fix

BZ#667031
IBus did not work on a minimal installation of Red Hat Enterprise Linux 6 if no desktop environment, such as KDE or GNOME, was installed. This issue was caused by the missing dbus-x11 package, which IBus is dependent on. The dbus-x11 package is now included as a prerequisite for IBus in the IBus spec file, and IBus now works as expected.
All users of ibus are advised to upgrade to these updated packages, which resolve this issue.

4.86. ibus-anthy

An updated ibus-anthy package that fixes a bug is now available for Red Hat Enterprise Linux 6.
The ibus-anthy package contains the Anthy engine, which provides an input method for Japanese based on the IBus (Intelligent Input Bus) platform.

Bug Fix

BZ#661597
Previously, when changing the Candidate Window Page Size setting of Other under the General tab, the im-chooser application had to be restarted for the changes to take effect. This problem has been fixed and the changes made to Candidate Window Page Size now apply immediately.
All users of ibus-anthy are advised to upgrade to this updated package, which resolves this bug.

4.87. ibus-table-erbi

An updated ibus-table-erbi package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The ibus-table-erbi provides the Simplified Chinese input method, ErBi.

Bug Fixes

BZ#712805
Prior to this update, the ibus-table-erbi spec file contained a redundant line which printed the debug message "/usr/share/ibus-table/tables" at the end of installation. The line indicated the working directory of the post-install script and has been removed to fix the problem.
BZ#729906
Previously, the table index was updated when running the post-install script of the ibus-table-erbi package. This modified the size of the files, the MD5 Message-Digest Algorithm checksum and the access time of database files. As a consequence, the "rpm -V" command failed with false positive warnings of the aforementioned changes due to the changes not matching the values in the package metadata. This has been fixed: files that are expected to be modified when running the post-install script are now specified with correct verify flags in the spec file.
All users of ibus-table-erbi are advised to upgrade to this updated package, which resolves these bugs.

4.88. icedtea-web

Updated icedtea-web packages that fix two security issues are now available for Red Hat Enterprise Linux 6.

The IcedTea-Web project provides a Java web browser plug-in and an implementation of Java Web Start, which is based on the Netx project. It also contains a configuration tool for managing deployment settings for the plug-in and Web Start implementations.
Security Fix
CVE-2011-3377
A flaw was found in the same-origin policy implementation in the IcedTea-Web browser plug-in. A malicious Java applet could use this flaw to open network connections to hosts other than the originating host, violating the same-origin policy.
All IcedTea-Web users should upgrade to these updated packages, which upgrade IcedTea-Web to version 1.0.6 to correct this issue. Web browsers using the IcedTea-Web browser plug-in must be restarted for this update to take effect.
An updated icedtea-web package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
IcedTea-Web provides a Java web browser plug-in, a Java Web Start implementation, and the IcedTea Web Control Panel.
The icedtea-web package has been upgraded to upstream version 1.1.4, which provides a number of bug fixes and enhancements over the previous version. (BZ#713514)

Bug Fixes

BZ#683479
The Java Web Start window invoked by the "javaws -about" command contained out-of-date information and could not be closed correctly. The information was out-dated because the Java Network Launching Protocol (JNLP) XML file defined inadequate access permissions to access the about.jnlp file, which contained the update information. With this update, the about information has been moved to an accessible location. The window failed to close as the respective process thread became unresponsive. Now, the window contains up-to-date information and the thread closes correctly.
BZ#718693
MindTerm SSH Applet failed to work as it was using class netscape.security.PrivilegeManager, which was not present in icedtea-web. This update adds the class and the applet works as expected.
BZ#731345, BZ#731358
Java Web Start and IcedTea plug-in sometimes failed to run as they were calling a java binary with a JDK-based path instead of a JRE-based path. With this update, the package spec file contains the correct definition of the path construction and javaws and icedtea-plugin call the correct java binary.
BZ#734081
When running an application with javaws, javaws failed to use the proxy settings from Firefox even though the respective setting was enabled ("Use browser settings") and failed over to the "DIRECT" mode. This happened because javaws was looking for the DEFAULT profile in the Firefox configuration file to acquire the current proxy settings. If it failed to locate the section with the DEFAULT profile, the default "DIRECT" mode was applied. With this update, javaws uses the settings from the last section under these circumstances.
BZ#741796
Starting from version 10, Elluminate did not work with IcedTea-Web. This happened because Elluminate specified Class-Path elements in its manifest file which caused a conflict with the jnlp-specified JARs. With this update, the IcedTea-Web plug-in no longer honors the Class-Path elements (just as the Oracle implementation) and Elluminate works with IcedTea-Web as expected.
All users of icedtea-web are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

4.89. initscripts

An updated initscripts package that fixes number of bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The initscripts package contains system scripts to boot the system, change runlevels, activate and deactivate most network interfaces, and shut the system down cleanly.
Bug Fixes
BZ#743222
Previously, the restorecon utility did not change MLS (multi-level security) levels unless the -F parameter was used. As a consequence, the /dev and /dev/pts filesystems were not correctly labelled after boot in systems with configured MLS policy. This bug has been fixed and the restorecon -F command is now used for /dev and /dev/pts by default.
BZ#734987
When an explicit configuration option, such as crashkernel=128M, was specified to reserve crash dump memory, the kexec-disable upstart job unconditionally freed up the memory if the kdump mechanism was not enabled. This action could not be reverted until a reboot. With this update, kexec-disable job has been changed to not free reserved memory, unless the crashkernel parameter is set to auto, thus fixing this bug.
BZ#675079
Previously, when the /etc/modprobe.d/bonding.conf file or the modprobe.conf file was used to set the bonding options, the bond0 interface never came up after a service restart because the arp_ip_target module was not restored. This bug has been fixed and arp_ip_target is now restored when configured in one of these files.
BZ#698520
Previously, there was a bug in the rc.sysinit script that allowed to properly set a hostname when more than one IP address was passed to the ipcalc utility. Even though it was difficult to emulate such a scenario, the rc.sysinit script has been fixed to prevent this bug, and ipcalc is now always passed only a single IP address.
BZ#700184
When a network interface was configured with the NetworkManager utility to statically assign an IP address or a prefix, then NetworkManager was stopped, and the interface was reset via the ifdown and ifup utilities, the interface lost its IP address. With this update, the network scripts have been fixed to properly read the IPADDR0 parameter in interface configuration files, and now IP addresses of such interfaces are preserved in the described scenario.
BZ#703475
Previously, when two VLAN interfaces were bonded together, the /etc/init.d/network script got into a loop and became unresponsive, trying to resolve MAC addresses of the interfaces. As a result, the server was prevented from completing its start-up sequence. With this update, /etc/init.d/network has been fixed, MAC addresses of VLAN interfaces are now resolved properly, and bonds between such interfaces now work as expected.
BZ#705367
Previously, when the PREFIX option was specified for the ifcfg utility while the NETMASK option was undefined, the netmask was calculated without regard to the PREFIX value. With this update, the expand_config() function has been fixed to use the PREFIX properly, and the netmask is now calculated correctly in the described scenario.
BZ#702814
When a system needed to be restarted after an unexpected termination, root password was not accepted to run the emergency shell. With this update, the rc.sysinit script has been fixed to run the /bin/plymouth command instead of /usr/bin/plymouth, thus fixing this bug. Additionally, other relevant scripts have been updated to properly work with the separated /usr/ directory.
BZ#703210
Due to a bug in the /etc/init.d/halt script, no mount point set up with the word nfs in its path could be unmounted at reboot or shut down. This bug has been fixed and such mount points are now unmounted properly.
BZ#681357
In Red Hat Entreprise Linux 6, when the emergency parameter was appended to the kernel command line, the system failed to invoke the sulogin command. With this update, the rcS-emergency task, which is run before the rc.sysinit script if emergency is passed to the kernel, has been added, and sulogin is now properly invoked in the described scenario.
BZ#729359
Due to a bug in the /etc/sysconfig/network-scripts/ifdown-eth script, the PID file name passed to the dhclient utility during a shutdown procedure did not include the IP version prefix. Consequently, leases for IPv6 addresses could not be released. This bug has been fixed and the shut down procedure now works properly both with the IPv4 and IPv6 clients.
Enhancements
BZ#692240
Previously, the ifup and ifdown scripts explicitly ignored IPv6 configuration files that contained an alias. With this update, clients properly utilize aliases on IPv6 devices in Red Hat Enterprise Linux.
BZ#653630, BZ#672202
There was a need to have a simple mechanism for troubleshooting network problems, integrated into existing log monitoring facilities. With this update, network scripts have been updated to report errors via the syslog utility, and the error messages now appear in configured syslog channels.
BZ#680527
Previously, configuration options for the sysctl utility could only be changed in the /etc/sysctl.conf file. With this update, several scripts have been updated to also recognize additional configuration files located in the /etc/sysctl.d/ directory.
BZ#692410
With this update, network start-up scripts have been enhanced to support all ethtool command options. These options can be set via the ETHTOOL_OPTS parameter in configuration files located in the /etc/sysconfig/network-scripts/ directory and take effect after reboot.
BZ#696788
With this update, start-up network scripts have been enhanced to set up static ARP (Address Resolution Protocol) entries located in the /etc/ethers file, allowing to load these entries early in the system startup.
Users of initscripts are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

4.90. ipa

An updated ipa package that fixes one security issue and several bugs is now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE link associated with the description below.
Red Hat Identity Management is a centralized authentication, identity management and authorization solution for both traditional and cloud based enterprise environments. It integrates components of the Red Hat Directory Server, MIT Kerberos, Red Hat Certificate System, NTP and DNS. It provides web browser and command-line interfaces. Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large scale Linux and UNIX deployments.
Security Fixes
CVE-2011-3636
A Cross-Site Request Forgery (CSRF) flaw was found in Red Hat Identity Management. If a remote attacker could trick a user, who was logged into the management web interface, into visiting a specially-crafted URL, the attacker could perform Red Hat Identity Management configuration changes with the privileges of the logged in user.
Due to the changes required to fix CVE-2011-3636, client tools will need to be updated for client systems to communicate with updated Red Hat Identity Management servers. New client systems will need to have the updated ipa-client package installed to be enrolled. Already enrolled client systems will need to have the updated certmonger package installed to be able to renew their system certificate. Note that system certificates are valid for two years by default.
Updated ipa-client and certmonger packages for Red Hat Enterprise Linux 6 were released as part of Red Hat Enterprise Linux 6.2. Future updates will provide updated packages for Red Hat Enterprise Linux 5.
Bug Fixes
BZ#705800
When installation of Identity Management clients failed, the debugging information shown in the /var/log/ipaclient-install.log file did not provide enough information to determine the cause of the failure. With this update, the /var/log/ipaclient-install.log file contains improved debugging messages that make it easier to debug a possible installation failure.
BZ#705794
The Identity Management services were not started after a reboot when the server was installed with the ipa-replica-install command. With this update, after an installation of a replica with ipa-replica-install, the ipa service is enabled using the chkconfig utility so that the Identity Management services are started and available after a reboot.
BZ#704012
Prior to this update, installing an Identity Management replica in a new IP subnet with an Identity Management-controlled DNS server failed. With this update, such operation no longer fails, although, the bind service needs to be restarted when a new reverse zone is added over LDAP.
BZ#703869
Previously, Identity Management replication installations were missing configuration for managed entries. As a consequence, user-private groups and netgroups were not created for host groups if they were created on the replica. This update adds the missing configuration, and user and host group creation work as expected.
BZ#723662
Prior to this update, GSSAPI credential delegation was disabled in the curl utility due to a security issue. As a result, applications that rely on delegation did not work properly. This update utilizes a new constructor argument in the xmlrpc-c client API to set the new CURLOPT_GSSAPI_DELEGATION curl option. This option enables the credential delegation, thus fixing this bug.
BZ#698421
An Identity Management replica would occasionally fail to install while trying to initialize replication with the remote Identity Management server. With this update, the memberOf attribute is rebuilt during installation, thus fixing this issue. Note that the 389 Directory Server (389-ds) may crash if it is restarted while this task is running. Wait for this task to complete before requesting a restart.
BZ#743253
For NIS compatibility reasons, when a host group is created, a net group with the same name is created as well. However, when a host group is created, it was not checked whether there was a net group with the same name already existent. As a consequence, the host group was created, but the net group could not be created and the user was not notified of this. With this update, when a new host group is created, the Identity Management server checks whether a net group with the specified name exists already. If there is such a group, the operation is denied.
BZ#743936
Prior to this update, the Identity Management web user interface loaded the entire Identity Management API name space when it was being started. As a result, JSON requests returned large amount of data, which caused certain browsers to report the script stack space quota is exhausted message and prevent a user from accessing the Web UI. This update split the Web UI initialization to several smaller calls. Browsers no longer report errors and the Web UI works as expected.
BZ#719656
Running the ipa-nis-manage command disabled the NIS listener and also removed the netgroup compatibility suffix. If NIS was disabled, the automatic creation of net groups was disabled as well. Thus, creating a host group would fail to automatically create a net group. With this update, disabling NIS has no effect on the automatic creation of net groups when host groups are created.
BZ#725433
Adding an indirect automount map to a mount point that already exists returned an error, but created the map anyway. As a result, the map could not be removed with Identity Management tools. With this update, the addition of an indirect map requires the creation of a key to store the mount point. If the addition of a map fails because the key already exists, the map is removed.
BZ#744264
Prior to this update, the Web UI Password Policy interface was missing some of the password policy fields that are present in the command line version (specifically, Max failures, Failure reset interval, Lockout duration, and Priority). As a result, users could not set these parameters via the Web UI and had to use the CLI version. This update adds all the missing Password Policy fields to the Web UI.
BZ#696193
When an Identity Management server A was using a KDC on Identity Management server B, and server B does down, on server A it looked as if server B was still operational. This caused clients to fail to enroll. With this update, the underlying source code has been modified to address this issue, and client enrollment works as expected.
BZ#742327
Permission objects related to DNS were improperly formatted and added before the relevant DNS privileges (that they were members of) were added to LDAP. DNS related permissions contain just limited information. Additionally, the privilege objects, which they were members of, lacked memberof LDAP attributes pointing back to the permissions. Thus, a user could get an incorrect list of permissions that were members of a DNS related privilege. With this update, permission objects formatting has been fixed and the missing memberof LDAP attributes in the relevant DNS privileges are properly added. Users now get a valid list of permissions (containing all the needed information) when displaying a DNS related privilege.
BZ#691531
A certificate not signed by the Identity Management Certificate Authority (CA) imported into Identity Management could not be managed by Identity Management. Performing any operations on a service or a host that would cause Identity Management to attempt to revoke a certificate would fail (for example, disabling or deleting a host or service). With this update, certificates issued by other CAs cannot be imported into an Identity Management host or a service record. Disabling and deleting hosts and services works as expected and correctly revokes certificates.
BZ#741808
An LDAP object migrated using the migrate-ds command could contain a multi-valued RDN attribute. However, the migrate-ds process picked only the first value of the RDN attribute and did not respect the value that was present in the DN in the migrated LDAP object. With this update, the value that is used in the original LDAP object DN is used, rather than the first value of a multi-valued RDN. As a result, LDAP objects with a multi-valued RDN attribute are migrated without any errors.
BZ#741677
When the ipa-client-install was run with the --password option containing a bulk password for client enrollment, the password could be printed to Identity Management client install log in a plain-text format. This behavior has been fixed, and passwords are no longer logged in the install log file.
BZ#726943
By default, the Identity Management Web UI adds a redirect from the web root to /ipa/ui. This makes it look like no other web resources may be used. With this update, during the installation process, the --no-ui-redirect option can be used to disable the default Rewrite rule. This may also be commented out manually in the /etc/httpd/conf.d/ipa-rewrite.conf. As a result, the web server root can point to any specified place. However, /ipa must remain available to Identity Management.
BZ#745957
The Identity Management Web UI did not take into account when a non-admin user was a member of an administrative role, which has more privileges than just performing self-service actions. With this update, non-admin users with an administrative role are shown the full administrative tabset as expected.
BZ#746056
Identity Management Web UI did not allow addition of an external user (that is, user that is not managed by Identity Management) as a RunAs user for a Sudo rule. An external RunAs user could be added to a Sudo rule via the command line only. With this update, adding an external user as a RunAs user is possible in the Web UI.
BZ#726123
The automountkey-del command includes a --continue option which has no function and does not affect anything. With this update, the --continue has been hidden, and will be deprecated in the next major release.
BZ#723622
Prior to this update, the ipa-getkeytab command failed with Bind errors. If 32-bit packages were used on a 64-bit system, the 32-bit cyrus-sasl-gssapi package was required. This update adds architecture-specific Requires to the RPM spec file, and retrieving of keytabs no longer fails.
BZ#707009
Installing an Identity Management server signed by an external CA fails with the following error:
cannot concatenate 'str' and 'NoneType' objects
This was because the required information was not being passed so the installation failed when constructing the Kerberos principal name for the Dogtag 389-ds instance. This information is now provided by the installer, thus fixing this issue.
BZ#727282
In the Identity Management Web GUI, attempting to view a certificate of a host returned the unknown command u'show' error message. Users could only use the command-line to view host certificates. The certificate buttons including Get, View, Revoke, and Restore for hosts and services have been fixed to use the correct entity name, and viewing of certificates in the Web UI works as expected.
BZ#726526
The number of ports that needed to be open between Identity Management replicas was too high. Managing such a number of ports required planning because new rules were needed for each replication agreement. With this update, Dogtag is now proxied via the existing Apache web server on ports 80 and 443, which already need to be open. Ports 944[3-6] no longer need to be open in the firewall.
BZ#727921
It is possible to add a host group as a member of a net group; however, that relationship did not appear when viewing a host group. With this update, net group membership is displayed when viewing a host group.
BZ#726715
When importing automaster maps, the auto.direct mount mounted on /- was ignored because it was considered a duplicate. Consequently, direct maps needed to be added manually. This update adds an exception for the auto.direct map when importing so that its keys can be added, and importing direct maps works as expected.
BZ#728118
The output of adding or showing a sudo rule with a runAsGroup included a reference to a ipasudorunasgroup_group attribute, making the output unclear. A proper label was added for runAsGroup and the sudo option, which makes the output more understandable.
BZ#728614
Using the ipa-replica-install did not ensure that the dbus service was running. Consequently, tracking certificates with certmonger returned an error and the installation failed. With this update, prior to starting certmonger, it is checked whether the dbus-daemon is running.
BZ#733436
The Identity Management server installer and ipactl use two different methods to determine whether Identity Management is configured. If the Identity Management uninstallation was not complete, ipactl may have claimed that the Identity Management server is not configured while the Identity Management server installer refused to continue because Identity Management was configured. With this update, a common function that checks whether the Identity Management server is configured has been added. During the uninstallation process of the Identity Management server, checks are run that report left-over files so that users can manually resolve these.
BZ#714238
Prior to this update, the error message returned when setting an integer value that was too large on 64-bit systems was confusing. This update limits the integer values to 2147483647 on all platforms, making error messages consistent on 32 and 64-bit systems.
BZ#729245
Adding an option to a sudo rule with the sudurole-add-option command did not display a summary after the option was added. With this update, a summary is printed in the form of Added option 'x' to Sudo Rule 'y'.
BZ#730436
Under rare circumstances, certain operations may have caused the 389 Directory Server (389-ds) to crash or not function properly. This was because NSPR (Netscape Portable Runtime) read/write locks used by 389-ds were not re-entrant. These locks were replaced with POSIX thread read-write locks in the Identity Management 389-ds plugins, and the aforementioned crashes no longer occur.
BZ#729246
Removing an option from a sudo rule with the sudurole-remove-option command did not display a summary after the option was removed. With this update, a summary is printed in the form of Removed option 'x' to Sudo Rule 'y'.
BZ#729377
Installing an Identity Management server using the --no-host-dns option without a DNS resolvable host name caused the installation to fail with DNS errors. This update moves the no-host-dns test so that it is tested before any DNS lookups occur, and installations with the --no-host-dns option do not perform any DNS validation.
BZ#732468
When Identity Management client A/PTR DNS records did not match, the ipa-getkeytab and ipa-join commands did not operate properly, and the client could not be enrolled to the Identity Management server. As a result, client installations failed every time. With this update, matching client A/PTR DNS records are no longer a requirement for ipa-getkeytab and ipa-join, and client installations succeed even when the aforementioned records do not match.
BZ#730713
Selecting a check box for users, groups, hosts, or host groups when deleting a list of objects in an HBAC rule in the Identity Management Web UI left the check box checked even when the operation was complete and the entry was re-edited. With this update, the selection is cleared when the page is refreshed.
BZ#730751
When editing an HBAC rule in the Identity Management Web UI, the delete button was enabled even when no selection was made. This update disables the delete button when nothing is selected.
BZ#729089
Removing an external host value by checking the update dns check box rendered the action successful even though the host was not removed. With this update, the host is removed successfully in the aforementioned scenario.
BZ#728950
If an 389-ds certificate expired, the Identity Management services did not start .This update adds new options for 389-ds which allow to control how 389-ds reacts to an expired certificate. The default setting is to warn the user and start the services.
BZ#729665
Checking/unchecking the Hide already enrolled check box when adding/removing members from a group had no effect. This update removes this check box.
BZ#726725
Passing an empty map name to the automountmap or automountkey command returned the following error:
Map: 
ipa: ERROR: 'automountmapautomountmapname' is required
This was because Identity Management tries to hide the LDAP implementation and often provides a different value for options and errors than is actually used. It may also use contrived internal names for uniqueness. With this update, Identity Management returns the correct values depending on the context so that a more useful error message is returned. As a result, in the aforementioned scenario, the correct value, automountmap, is now returned.
BZ#714600
The default SSSD configuration did not store passwords if offline. Consequently, when a machine was disconnected from the network, SSSD was unable to authenticate any users. With this update, the krb5_store_password_if_offline parameter is set to True in the /etc/sssd/sssd.conf by default. Note that the --no-krb5-offline-passwords option of the ipa-client-install command may be used if storing passwords for offline use is not desired.
BZ#726722
Passing an empty location to the automountmap or automountkey command returned the following error:
Location: 
ipa: ERROR: 'automountlocationcn' is required
This was because Identity Management tries to hide the LDAP implementation and often provides a different value for options and errors than is actually used. It may also use contrived internal names for uniqueness. With this update, Identity Management returns the correct values depending on the context so that a more useful error message is returned. As a result, in the aforementioned scenario, the correct value, automountlocation, is now returned.
BZ#714919
Prior to this update, the ipa-client-install command did not configure a hostname in the /etc/sysconfig/network file. Consequently, when the --hostname value was passed to the client installer, that value was used during enrollment. However, the system hostname did not match the name of the machine. With this update, the /etc/sysconfig/network file is updated upon installation and /bin/hostname is executed with the hostname of the machine. The name used in the enrollment process now matches the hostname of the machine.
BZ#715112
Renaming users (via ipa user-mod --setattr) may have returned a Not Found error. Renaming the actual users was successful, but their user-private groups were not updated. With this update, the 389-ds plugin has been modified so that the ipa_modrdn plugin runs last. This plugin manages renaming of the Kerberos principal name of the user. Renaming a user now also renames the user-private group.
BZ#736684
If an Identity Management client was installed and there was a too large of a time difference between the client and the Identity Management server, a KDC running on the Identity Management server may have refused any Kerberos authentication request from the client. Consequently, the installation process could fail as it could not get a valid Kerberos ticket. With this update, time is always synchronized with the NTP servers configured for the client domain or the Identity Management server itself. If the time synchronization succeeds, the time on the client machine is fixed and Kerberos authentication and the installation itself successfully continue.
BZ#737048
The ipa-client-install command always ran /usr/sbin/authconfig to add the pam_krb5.so entry to PAM configuration files in the /etc/pam.d/ directory. However, this entry was not needed when an Identity Management client is installed with SSSD support, which is the default behavior. As a result, an unnecessary record was added to the PAM configuration. With this update, /usr/sbin/authconfig is not run if the Identity Management client is configured with SSSD support.
BZ#717724
The certificate subject base was editable post-install which caused the change to not be propagated to the CA. With this update, the certificate subject base is read-only and the value cannot be modified post installation.
BZ#737581
Prior to this update, a new host could be added to an Identity Management server without proper validation. For example, a host with an invalid hostname or a hostname containing a whitespace character could be created. With this update, proper validation of hostnames for any host has been added, and only hosts with valid hostnames can now be added to an Identity Management server.
BZ#717965
The Identity Management configuration stored a value for Password Expiration Notification but did not display it by default (when using the ipa config-show command). This update adds Password Expiration Notification to the default list of attributes to shown by default when running the ipa config-show command.
BZ#745698
Identity Management installation tools accepted invalid IP addresses in their --forwarder or --ip-address options. Consequently, installation could eventually fail, for example because of an invalid name server configuration. With this update, all IP addresses passed to the ipa-server-install, ipa-replica-install and ipa-dns-install commands are checked for validity.
BZ#739040
When the ipa-client-install command detected that the client hostname was not resolvable, it tried to add a DNS record to the Identity Management server. However, it did not expect that the client could have been using an IPv6 machine, and the installation process failed. This update adds a check to make sure that the process for adding a DNS record to the Identity Management server works for both IPv4 and IPv6, and the Identity Management client installation works as expected.
BZ#739640
When a new service was added via the Add New Service Web UI dialog box, the Web UI did not check if the service name field was filled in. When the dialog box was confirmed with the service name field empty, a new service named undefined was created. With this update, the service name field is required to be filled in.
BZ#693496
Prior to this update, the ipa-nis-manage tool crashed with a python exception when attempting to use an LDAPI connection only. With this update, ipa-nis-manage correctly falls back to GSSAPI or a password-based authentication if the LDAPI connection fails.
BZ#723233
An attempt to create a rule with an invalid type returned an error which informed users that only allow and deny are accepted as types:
ipa: ERROR: invalid 'type': must be one of (u'allow', u'deny')
However, rules of the type deny are not allowed. With this update, the deny type was deprecated because SSSD determined that properly enforcing the deny type was extremely difficult and dependent on how other libraries present host information.
BZ#743680
The ipa-server-install command did not update the system hostname when it was installed with a custom hostname. It passed the hostname to services using their own configurations. However, some services failed to function properly as they did not expect an Identity Management server to use a custom hostname and not a system hostname. With this update, the system hostname is updated to the value passed via ipa-server-install's --hostname option. The system hostname is also set in the system network configuration in /etc/sysconfig/network so that it is properly set after a system reboot. Refer to Section 2.8, “Authentication” for a known limitation regarding Identity Management server installations with custom hostnames.
BZ#707001
When installing an Identity Management server and using an external CA to sign it, the specified command line options were not properly validated. In such a case, the resulting CSR contained only the string null. This update adds better detection of whether the CA 389-ds instance has been installed to identify the current stage of the installation, thus fixing this issue.
BZ#723778
When deleting an automount location, the command appeared to be successful, but there was no feedback provided on the output. With this update, a summary of all automount commands is shown.
BZ#723781
When adding an automount location, the command appeared to be successful, but there was no feedback provided on the output. With this update, a summary of all automount commands is shown.
BZ#707133
Prior to this update, the ipa-nis-manage command did not return an exit status of 0 when successful. With this update, the underlying source code has been modified to address this issue, and correct exit codes are returned.
BZ#737997
When a new user was added, its login was normalized and lower-cased. However, its principal was not normalized and contained the original login. Consequently, if a new user with an uppercase letter in its login was added, a disconnect between a user login and its principal was created. The Identity Management server then refused to create a password for that user. This update normalizes both the new user long and its principal, thus fixing this issue.
BZ#737994
Certain Identity Management commands require a file to be passed. For example, a cert-request command requires a CSR file. If the command contains a validation rule for the required file, it needs to be executed before it can be processed. However, if the file was passed in the CLI command interactively (and not as a command option), the validation rule was applied to the file path and not the file contents. As a result, a validation rule could fail and the command then returned an error until the file was passed as a command option. With this update, a validation rule is applied to file contents only, and users can pass the required file on the command line both interactively and via a command option.
BZ#726454
Previously, there was no indicator in a host entry that a one-time password was set. This update adds a new output attribute for host entries, has_password, that is set when the host has a password set. If has_password is True, a password has been set on the host. However, there is no way to see what that password is once it has been set.
BZ#716287
When a host is enrolled, the user that does the enrollment is stored in the attribute enrolledBy on the host. Prior to this update, an administrator was able to change this value by using the ipa host-mod --setattr. This action should not be allowed. This update fixes this behavior and write permissions have been removed from the enrolledBy attribute.
BZ#714924
When configuring an Identity Management client to use SSSD, if an error occurred while looking up users, the following error message was displayed:
nss_ldap is not able to use DNS discovery
This update modifies this error message to be more specific.
BZ#736617
The ipa-client-install command did not configure /usr/sbin/ntpdate to use correct NTP servers in the /etc/ntp/step-tickers. Additionally, the ipa-client-install did not store the state of the ntpd service before installation. Consequently, when an Identity Management client is installed, ntpdate may have used incorrect servers to synchronize with. When the Identity Management client was uninstalled, the ntpd may have been set to an incorrect state. With this update ipa-client-install configures ntpdate to use the IPA NTP server for synchronization. When an IPA client is uninstalled, both ntpdate configuration and ntpd status are restored.
BZ#714597
The IPA-generated /etc/krb5.conf file contained values which were not present in the standard configuration file (specifically: ticket_lifetime, renew_lifetime, and forwardable in the [libdefaults] section, and the entire [appdefaults] section). This update removes these unnecessary values and sections.
BZ#680504
DNS forward and reverse entries are stored discretely. Removing one does not remove the other unless specifically requested. Previously, it was unclear how to remove the required entries. This update adds a new interactive mode (via ipa dnsrecord-del) to the command line application which guides the user through the process of removing the required entries.
BZ#725763
Summary data displayed when adding an automount key has been modified to include the map and the key.
BZ#717625
Updating values in the configuration tab in the Identity Management Web UI returned an error. This was because the Web UI was searching for a primary key configuration. With this update, it no longer searches for the key, and the configuration tab works as expected.
BZ#717020
When activating or deactivating a user in the Identity Management Web UI, the user is updated without having to click the Update button. With this update, a message box is displayed indicating that the change is going into effect immediately.
BZ#716432
If 389-ds debugging was enabled, superfluous content appeared in the ipactl output. With this update, the amount of information displayed in the ipactl output has been reduced. The previously reported data is not available in the 389-ds error log only.
BZ#714799
The ipa-client-install did not successfully run on a client when a one-time password was set on a host in the Identity Management Web UI. Consequently, clients could not be enrolled using a one-time password if it was set in the Web UI. With this update, the krbLastPwdChange value is no longer set in the host entry when setting a host one-time password, thus fixing this issue.
BZ#713798
Prior to this update, DNS lookups were not being forwarded if they originated in a subnet that was not managed by Identity Management. With this update, the Identity Management DNS is configured to allow recursion by default, thus fixing this issue.
BZ#713481
When removing a runAsGroup value from a sudo rule, the command appeared to be successful, but the group information data included in the output was not updated and did not show the proper membership. This update fixes this bug, and data is refreshed before being returned.
BZ#713380
When removing a runasuser (via ipa sudorule-remove-runasuser) and, consequently, defining a group, the RunAs Group value was not included in the output. This was because the label for the returned data was mislabeled and was not appearing in the output. With this update, the underlying source code has been modified to address this issue, and adding a group to runasuser is properly displayed.
BZ#713069
Comma-separated values were not handled properly when the --externaluser option was specified for the sudorule-mod command. As a result, erroneous values were stored in the entry. With this update, the --externaluser option was removed from the sudorule-mod command. It is advisable to use the sudorule-add-user command instead.
BZ#731804
Upgrading Identity Management from version 2.0.0-23 caused the 389-ds configuration to be modified to not accept requests. With this update, the upgrade process is more robust and always restores the 389-ds configuration. As a result, upgrading Identity Management no longer leaves the system in an inconsistent state.
BZ#731805
Different error types could cause various error messages to appear in the Identity Management Web UI. This update makes all error messages in the Web UI consistent.
BZ#732084
Disabling SELinux (SELINUX=disabled in /etc/selinux/config) and attempting to restart the ipa service caused the ipa service to fail to start. This update ignores the value returned by restorecon, and the ipa service now starts as expected whether SELinux is enabled or disabled.
BZ#712889
A request to set a certificate revocation reason to 7 would cause the request to fail and the certificate was not revoked. Reason 7 is not a valid revocation reason according to RFC 5280. With this update, an error message is returned to the user, informing of the fact that, when used, reason 7 is not a valid revocation reason.
BZ#726028
Previously, renaming an automount key did not work properly because DN of the key was being updated but not the value within the entry. Renaming an automount key now updates the DN and the stored key value, thus fixing this issue.
BZ#711786
When setting runAsGroup in a sudo role as a user, the name of that user is returned as the name of a group that may also be used as the runAsGroup. As a result, the sudo rule was erroneous and referred to a non-existent group. This was because the search filter for determining the CN value was too generic. This update adds a test which assures user names no longer appear as runAsGroup values.
BZ#711761
Prior to this update, removing a sudo rule option failed on the server because the code which handled sudo rule option removal was not robust enough and if the input did not exactly match the stored value, it failed. With this update, removing sudo rule options works as expected.
BZ#711671, BZ#711667
Previously, comma-separated values were not handled properly when using sudorule-mod's --runasexternaluser or --runasexternalgroup options. With this update, the aforementioned options have been deprecated. It is advisable to use the sudorule-add-runasuser or sudorule-runasgroup commands instead.
BZ#710601, BZ#710598, BZ#710592
Prior to this update, leading and trailing spaces were allowed in some parameter values. This update adds a validator that disallows the use of leading and trailing spaces.
BZ#710530
Passing an empty password when prompted to by the ipa-nis-manage command did not display an error and did not exit the command. With this update, passing an empty password causes an error to appear (No password supplied), and the command is exited with the status code 1.
BZ#710494
The ipa-nis-manage command has an option, -y, to specify the Directory Manager password in a file. This option caused the command to crash if the file did not exist. An exception handler around the password reader has been added, and a proper error message is displayed when the supplied password file is non-existent or is not readable.
BZ#710253
When adding a runasuser (via ipa sudorule-add-runasuser) and, consequently, defining a group, the RunAs Group value was not included in the output. This was because the label for the returned data was mislabeled and was not appearing in the output. With this update, the underlying source code has been modified to address this issue, and adding a group to runasuser is properly displayed.
BZ#738693
A user with a valid Kerberos ticket can change an IPA password with the ipa passwd command. Prior to this update, the command did not require entering the old password. Consequently, anyone with access to that user's shell could change his Identity Management password without knowing the old password. With this update, the old password is always required in order to change a user's password. The only exception is the administrator user.
BZ#710245
A removed sudorule option appeared in the output when that option was removed. With this update, option values are refreshed before being returned, and the output of the delete command is consistent with the actual data.
BZ#710240
Adding a duplicate sudorule option did not generate any errors messages. With this update, rather than ignoring duplicate values, an error is returned when a duplicate sudorule option is added.
BZ#739195
When attempting to unprovision a host keytab in the Identity Management Web UI Unprovisioning Host dialog, there was no option to cancel the process. This update adds the Cancel button to the Unprovisioning Host dialog.
BZ#709665, BZ#709645
When removing external hosts from a sudorule, the output shown after the command completed contained the hosts that were removed. With this update, external host information is refreshed before it is returned to the client.
BZ#707312
Previously, new DNS zones were not available until the bind service was restarted. With this update, an updated bind-dyndb-ldap package added a zone refresh option that Identity Management uses to refresh the zone list in DNS. The default setting is 30 seconds. As a result, new DNS zones are not immediately available, but the bind service does not have to be restarted anymore.
BZ#740320
When a new group was being created via the Identity Management Web UI, unchecking the Posix check box was not taken into account and a posix group was created every time. With this update, the underlying source code has been modified to address this issue, and creating non-posix groups works as expected.
BZ#707229
The --no-host-dns option of the ipa-server-install command still checked that the forward and reverse DNS entries existed and matched. Installation of an Identity Management server using a host name that could not be resolved would then fail. This update removes any DNS validation when the --no-host-dns option is used.
BZ#705804
The subject name of a CA agent certificate used by Identity Management was not very specific. This update changes the subject name from RA Subsystem to IPA RA.
BZ#702685
If a remote LDAP server that was being used while migrating to Identity Management contained an LDAP search reference, the migration failed. With this update, the migration process logs any search references and skips them, assuring a successful migration.
BZ#740885
For an HBAC rule, you can choose to add a host in the Accessing section of the Identity Management Web UI. Clicking on Enroll without selecting a host did not return an error indicating that a host was not selected. With this update, the Enroll button is disabled until a host is chosen.
BZ#740891
For an HBAC rule, you can choose to delete a host in the Accessing section of the Identity Management Web UI. Clicking on Enroll without selecting a host did not return an error indicating that a host was not selected. With this update, the Enroll button is disabled until a host is chosen.
BZ#741050
The ipa-client-install command always checked the specified server whether it was a valid Identity Management server. However, if the Identity Management server was configured to restrict access for anonymous binds (via the nsslapd-allow-anonymous-access option), the check failed and the installation processes returned an error and ended. With this update, when the ipa-client-install command detects that the chosen server does not allow anonymous binds, it skips server verification, reports a warning, and lets the user join the Identity Management server.
BZ#701325
The X509v3 certificate shown in a host or service record in the Identity Management Web UI was not properly formatted. This update converts the certificate from the base64 format to the PEM format.
BZ#698219
The Apache service communicates with 389-ds early on during the start-up (to attempt to retrieve the LDAP schema). Previously, if that communication failed, the Apache service would have to be restarted. This race condition could cause a restarted Identity Management server become unavailable. With this update, the communication between Apache and 389-ds is retried when it fails, thus fixing this issue.
BZ#697878
The Identity Management server installation could fail with an error informing of the fact that the LDAP server could not be reached. This was because the installation process did not wait for the 389-ds server to fully start after a restart. With this update, the installation process waits for the 389-ds server to be fully started.
BZ#742875
When an Identity Management server was installed, it did not properly check the system's static lookup table (/etc/hosts) for records which could interfere with its IP address or hostname, and cause forward or reverse DNS queries to be resolved to different values than expected. The installation process now always checks for any conflicting records in the /etc/hosts file.
BZ#696282
A certificate subject base with an incorrect format provided by the user could cause an installation process to fail in the CA step with a non-descriptive error. With this update, the subject base of a certificate is validated, and the installation no longer fails.
BZ#696268
Providing an IP address during the Identity Management server installation via the --ip-address option caused the installed server to not function properly. With this update, it is verified whether the provided IP address is a configured interface on the system. Providing an IP address that is not associated with a local network interface will return an error message.
BZ#743788
The IPA Web UI was missing a title on several pages. This update adds the missing titles.
BZ#693771
Including non-ASCII characters in the zonemgr email address could cause an installation to fail with an unclear message. This update adds a validator which requires the zonemgr to contain ASCII characters only.
BZ#681978
Uninstalling an Identity Management client on a machine which has the Identity Management server installed on it as well caused the server to break. The client uninstaller now detects the installation state of an installed server. An attempt to uninstall a client from a machine which also contains the server will result in an error message. The client can be uninstalled when the server is uninstalled.
BZ#744024
Prior to this update, the ipa-client-install command did not return an exit status of 0 when successful. With this update, the underlying source code has been modified to address this issue, and correct exit codes are returned.
BZ#744074
Prior to this update, the Identity Management Web UI allowed a user to delete a global Password Policy. If a global Password Policy is deleted, any attempt to add a user with a Kerberos password fails. Additionally, neither the CLI nor the Web UI version of Identity Management could be used to add this policy back. With this update, deleting the global Password Policy is denied.
BZ#692955
Attempting to set the manager value of a user resulted in the following error message:
value #0 invalid per syntax: Invalid syntax.
This was because the value required a full LDAP DN syntax. With this update, when storing or retrieving the manager value, the value is automatically translated between a login name and a DN. Setting the manager value now requires a login name only.
BZ#744422
During the installation of a Identity Management server, the ipa-server-install called kdb5_ldap_util to populate the directory with realm information. In the process of doing so, it passes the Kerberos master database password and the Kerberos directory password as parameters. As a result, a user could list all running processes during the IPA server installation and discover the aforementioned passwords. With this update, kdb5_ldap_util's interactive mode is used to pass the passwords instead of passing them via CLI parameters.
BZ#692950
When setting up DNS during an interactive installation, a reverse zone was always created regardless of the --no-reverse option. This update fixes this behavior, and a reverse zone is not created unless specified.
BZ#745392
When the ipa-client-install command attempted to auto-discover the Identity Management server in its domain, it did not use any timeout when a server was found and was being checked. If the found server was unresponsive during the auto-discovery, the ipa-client-install command got stuck and did not continue. This update adds a 30 second timeout to the ipa-client-install auto-discovery server check.
BZ#692144
Using the --no-sssd option of the ipa-client-install command did not properly back up and restore the existing /etc/sssd/sssd.conf file. With this update, the underlying source code has been modified to address this issue, and the --no-sssd option works as expected.
BZ#690473
Using the --hostname option to set a value outside an Identity Management-managed DNS domain did not return an error and did not add the host to DNS. The DNS updating utility, nsupdate, was modified to properly return an error when an update fails.
BZ#690185
Uninstalling an Identity Management client did not restore certain files when that client was previously installed with the --force option. This was because the --force option was able to re-install over an already installed system, causing the original saved files to be lost. This behavior is no longer permitted; the client must be first uninstalled and only then it can be re-installed.
BZ#689810
Adding a duplicate user resulted in a generic error message which was not specific enough to discover the reason of the error. With this update, the object type and the primary key are returned in the error message, making the error message more understandable.
BZ#689023
When adding a new password policy, the Identity Management Web UI did not prompt for a required field, priority. This update requires the priority field to be filled in.
BZ#688925
The process of setting up an Identity Management replica became unresponsive if the master could not be reached. This update adds a new utility, ipa-replica-conncheck, which verifies that the replica and the master can communicate in both directions.
BZ#688266
If the domain did not match the realm, enrolling a client could fail with the following error:
Cannot resolve network address for KDC
This was because a temporary /etc/krb5.conf file was used during enrollment to contact the Identity Management KDC. The process was always relying on DNS auto-discovery to find the correct KDC and not the values provided by the end-user. With this update, enrollment works even if the domain does not match the realm.
BZ#683641
If a one-time password was set on a host, an administrator was unable to enroll it and the following error message would be returned:
No permission to join this host to the IPA domain.
A delegated administrator did not have permissions to write the Kerberos principal name. This update adds permissions for the delegated administrator to be able to add a one-time password, but not change or remove an existing one.
BZ#681979
The --on-master lacked proper documentation. This update makes the option invisible and removes it from documentation entirely.
BZ#747443
Realm-Domain mapping was not specified in a client's Kerberos configuration when the client was outside of an Identity Management domain. In such a case, Certmonger would fail to issue a host certificate. Realm-Domain mapping is now properly configured when the client is outside of the Identity Management domain.
BZ#748754
Arguments for the Kerberos KDC, contained in the /etc/sysconfig/krb5kdc file, were not formatted properly on multi-CPU systems. As a consequence, the KDC could not use the intended number of CPUs and reported an error when it was (re)started. With this update, the aforementioned arguments are now properly formatted, fixing this issue.
BZ#749352
Prior to this update, the ypcat command's netgroup output did not show users in netgroup triples. Consequently, NIS-based authorization did not work as expected, and access was denied when it should have been allowed. This was caused by a syntax error in the triple rule. This update fixes this error, and users are now properly included in the netgroup triples.
BZ#736170
The ipa package has been upgraded to upstream version 2.1.3 which provides a number of bug fixes and enhancements over the previous version.
Users are advised to upgrade to these updated ipa packages, which resolve these issues.
Updated ipa packages that fix a bug are now available for Red Hat Enterprise Linux 6.
Red Hat Identity Management is a centralized authentication, identity management and authorization solution for both traditional and cloud based enterprise environments. It integrates components of the Red Hat Directory Server, MIT Kerberos, Red Hat Certificate System, NTP and DNS. It provides web browser and command-line interfaces. Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large scale Linux and UNIX deployments.

Bug Fix

BZ#729805
Prior to this update, GSSAPI credential delegation was disabled in the curl utility due to a security issue. As a result, applications that rely on delegation did not work properly. This update utilizes a new constructor argument in the xmlrpc-c client API to set the new CURLOPT_GSSAPI_DELEGATION curl option. This option enables the credential delegation, thus fixing this bug.
Users of ipa are advised to upgrade to these updated packages, which fix this bug.
Updated ipa packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Its administration tools allow an administrator to quickly install, set up, and administer a group of domain controllers to meet the authentication and identity management requirements of large scale Linux and UNIX deployments.

Bug Fixes

BZ#709329
When an IPA server was installed and then a replica package for a replica server was generated, the installation of the replica server failed. With this update, the installation process waits for the 389DS (389 Directory Server) tasks to complete before restarting the server, fixing this bug.
BZ#709330
Previously, the ipa service was not enabled via the chkconfig tool during the installation of a replica server. Subsequently, when the replica server was restarted, the ipa service was not started. With this update, replica servers are properly configured to start on boot.
BZ#709331
After a replica server was installed, the Managed Entries were not properly configured on replica servers. Subsequently, users had to manually add the configuration using the ldapmodify tool after the replica installation, and then restart the services with the "ipactl restart" command. This bug has been fixed and the configuration is now automatically added as expected.
BZ#709332
When a new reverse zone was created via the ipa-replica-prepare script, the wrong DNS entry was updated, which eventually caused an installation of a replica server to fail. This bug has been fixed and when the named service is restarted after a replica package has been created, the correct DNS entries are now set up for an installation of a replica server.
All users of ipa are advised to upgrade to these updated packages, which fix these bugs.

4.91. ipa-pki-theme

Updated ipa-pki-theme packages which fix this bug are now available for Red Hat Enterprise Linux 6.
The ipa-pki-theme packages provide Red Hat Identity Management theme components for PKI packages.
Certificate System (CS) manages enterprise Public Key Infrastructure (PKI) deployments and requires a theme for the specific type of PKI deployment with which it is used. This package makes a Red Hat Identity Management theme available for CS, and therefore makes it possible for users of Red Hat Enterprise Linux 6 to use CS as a part of Red Hat Identity Management deployments.

Bug Fix

BZ#712931
Red Hat Identity Management is a centralized authentication, identity management and authorization solution for both traditional and cloud based enterprise environments. Prior to this update, Certificate System (CS), which is implemented in pki-core, required multiple ports to be open in a firewall for IPA to work. The number of open ports required has been reduced, and support for a proxy using Apache JServ Protocol (AJP) ports has been added, by enhancements made in pki-core. With this update, ipa-pki-theme has been changed to make use of the updates to CS, including adding the proxy-ipa.conf configuration file, and fixing broken links in certain user interface files. As a result, it is now possible for ipa-pki-theme to support running CS behind a proxy Apache server.

Important

This theme is mutually exclusive with the PKI themes for other types of PKI deployments, such as dogtag-pki-theme for Dogtag Certificate System deployments and redhat-pki-theme for Red Hat Certificate System deployments. (BZ#643543)
All users of ipa-pki-theme are advised to upgrade to these updated packages, which fixes this bug.

4.92. ipmitool

An updated ipmitool package that fixes multiple bugs is now available for Red Hat Enterprise Linux 6.
The ipmitool package contains a command line utility for interfacing with devices that support the Intelligent Platform Management Interface (IPMI) specification. IPMI is an open standard for machine health, inventory, and remote power control.

Bug Fixes

BZ#675975
Prior to this update, ipmitool's Serial Over LAN (SOL) module erroneously calculated the number of octets processed by the Baseboard Management Controller and could have resent already acknowledged chunks of serial communication, which could have corrupted the serial line with additional characters. Under certain circumstances, this could have also brought ipmitool into an endless loop or unexpected termination. With this update, ipmitool now correctly calculates the number of octets processed by the BMC and does not resend unwanted characters over the serial line.
BZ#727314
This update improves integration of the Linux Multiple Device (MD) driver with ipmitool to indicate the SCSI enclosure services (SES) status and drive activities for the PCIe SSD based solutions.
BZ#726390
This update adds the "channel setkg" subcommand to the "ipmitool" command, which allows for KG key configuration.
BZ#726390
This update adds the "-Y" option, which allows reading of the KG key from the terminal.
BZ#731977
A serial console connected to over the LAN and activated with the command "ipmitool sol activate" contained a memory leak, which could have consumed all available memory resources over time. This update fixes the problem.
BZ#731718
Invoking "ipmitool delloem powermonitor" did not properly convert values received over the network to integer numbers on big-endian systems (PowerPC, IBM System z). As a result, mostly random values were displayed when reporting power consumption. This update fixes the integer conversions in the "powermonitor" command so that the power consumption is now reported correctly on PowerPC and IBM System z architectures.
All users of ipmitool are advised to upgrade to this updated package, which fixes these bugs.

4.93. iproute

An updated iproute package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
The iproute package contains networking utilities (ip and rtmon, for example) which are designed to use the advanced networking capabilities of the Linux kernel.

Bug Fixes

BZ#692867
Prior to this update, the "ip" utility lacked the "mode" parameter support for macvtap devices. As a consequence affected users could not create macvtap devices in "bridge" or "private" modes. With this update the "ip" utility now fully supports macvtap devices along with the "mode" parameter and its options, "bridge", "private", and "vepa" (default). As a result users can now utilize macvtap functionality via the iproute package.
BZ#693878
Prior to this update, the "ip" tool lacked the "passthru" mode parameter support for macvtap and macvlan devices. Consequently users could not create macvtap and macvlan devices in "passthru" mode. The "ip" tool now fully supports macvtap and macvlan devices along with the "mode" parameter and its options, "bridge", "private", "passthru", and "vepa" (default). As a result users can now utilize "passthru" mode as part of macvtap and macvlan functionality via the iproute package.
BZ#709652
Prior to this update, the "tc" utility ignored GRED (Generalized RED) queue options. Consequently "tc" users could not configure certain GRED queue related parameters. With this update the "tc" utility no longer accidentally overwrites the user specified options. As a result "tc" users can now reliably define all GRED parameters.
All users of iproute are advised to upgrade to this updated package, which fixes these bugs.

4.94. iprutils

An updated iprutils package that fixes various bugs and provides one enhancement is now available for Red Hat Enterprise Linux 6.
The iprutils package provides utilities to manage and configure SCSI devices that are supported by the IBM Power RAID SCSI storage device driver.
The iprutils package has been upgraded to upstream version 2.3.4, which provides support for the Serial Attached SCSI (SAS) vRAID functions. (BZ#693816)

Bug Fixes

BZ#694756
Due to a NULL pointer dereference, the iprconfig utility terminated unexpectedly with a segmentation fault when attempting to display hardware status. A patch has been applied to address this issue and hardware status is now displayed correctly.
BZ#703255
Previously, iprutils did not work correctly when performing RAID migration and asymmetric access functions on new adapters. With this update, array migration functionality is fixed. Now, iprutils can correctly perform the raid migration and asymmetric access functions.
BZ#741835
The find_multipath_vset routine used the ARRAY_SIZE() macro to calculate the length of the serial number. Previously, the length was calculated incorrectly, which could have led to false positives when looking for the corresponding vset. As a consequence, attempting to delete arrays failed: the target and the second array were set to be read/write protected, writing to both arrays was not possible, and the system had to be rebooted. To fix the problem, the IPR_SERIAL_NUM_LEN macro is now used instead of ARRAY_SIZE.
BZ#741835
With the maximum number of devices attached to one of the new Silicon Integrated Systems (SiS) 64-bit adapters, the configuration data could have grown over the buffer size. With this update, the buffer size has been increased, which fixes the problem and ensures room for any possible future growth.
All users of iprutils are advised to upgrade to this updated package, which fixes these bugs and provides this enhancement.

An updated iscsi-initiator-utils package that fixes one bug and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The iscsi package provides the server daemon for the Internet Small Computer System Interface (iSCSI) protocol, as well as the utility programs used to manage it. iSCSI is a protocol for distributed disk access using SCSI commands sent over Internet Protocol networks.

Bug Fix

BZ#715434
The iscsiadm utility displayed the discovery2 mode in the help output but did not accept the mode as a valid one. This entry has been replaced with the valid discoverydb mode entry as displayed in the ISCSIADM(8) manual page.

Enhancements

BZ#602959
The brcm_iscsiuio daemon did not rotate its log file, /var/log/brcm-iscsi.log. As a consequence, the log file may have filled up the available disk space. The brcm_iscsiuio daemon now supports log rotation, which fixes the problem.
BZ#696808
The brcm_iscsiuio daemon has been updated to provide enhanced support for IPv6 (Internet Protocol version 6), VLAN (Virtual Local Area Network), and Broadcom iSCSI Offload Engine Technology. The daemon has been renamed to iscsiuio with this update.
BZ#749051
The bnx2i driver can now be used for install or boot. To install or boot to targets using this driver, turn on the HBA (Host Bus Adapter) mode in the card's BIOS boot setup screen.
In addition, the iSCSI tools can now set up networking and manage sessions for QLogic iSCSI adapters that use the qla4xxx driver. For more information, see section 5.1.2 of the README file which is located in the /usr/share/doc/iscsi-initiator-utils-6.2.0.872 directory.
Users are advised to upgrade to this updated iscsi-initiator-utils package, which fixes this bug and adds these enhancements.

The isdn4k-utils package contains a collection of utilities needed for configuring an ISDN subsystem.

Bug Fixes

BZ#618653, BZ#618549
Prior to this update, the isdn and capi init scripts were not LSB compatible. Due to this problem, the isdn and capi init scripts exited with incorrect or invalid exit statuses. This update modifies the init scripts so that they are LSB compatible. Now the init scripts exit with the correct exit status.
All users of isdn4k-utils are advised to upgrade to these updated packages, which fix this bug.

4.102. jwhois

An updated jwhois package that fixes one bug and adds one enhancement is now available for Red Hat Enterprise Linux 6.
The jwhois package provides a whois client, which is used to obtain information about domain names and IP addresses from whois servers.

Bug Fix

BZ#682832
Previously, when querying a domain with the name length near the allowed limit of 63 characters, and emitting command options to a whois server, the "whois" command failed because both the domain name and command options were given to a function responsible for translating Internationalized Domain Names (IDN) to ASCII. The length of such command was greater than the allowed limit. This update fixes this bug so that only the domain name is now translated after executing the command.

Enhancement

BZ#664449
Previously, jwhois did not contain the whois server details for the dotEmarat extension. As a result, whois queries for these extensions were incorrectly directed to whois.internic.net.

Bug Fixes
BZ#713682
When a host was in recovery mode and a SCSI scan operation was initiated, the scan operation failed and provided no error output. This bug has been fixed and the SCSI layer now waits for recovery of the host to complete scan operations for devices.
BZ#712139
In a GFS2 file system, when the responsibility for deallocation was passed from one node to another, the receiving node may not have had a fully up-to-date inode state. If the sending node has changed the important parts of the state in the mean time (block allocation/deallocation) then this resulted in triggering an assert during the deallocation on the receiving node. With this update, the inode state is refreshed correctly during deallocation on the receiving node, ensuring that deallocation proceeds normally.
BZ#712131
Issues for which a host had older hypervisor code running on newer hardware, which exposed the new CPU features to the guests, were discovered. This was dangerous because newer guest kernels (such as Red Hat Enterprise Linux 6) may have attempted to use those features or assume certain machine behaviors that it would not be able to process because it was, in fact, a Xen guest. One such place was the intel_idle driver which attempts to use the MWAIT and MONITOR instructions. These instructions are invalid operations for a Xen PV guest. This update provides a patch, which masks the MWAIT instruction to avoid this issue.
BZ#712102
The 128-bit multiply operation in the pvclock.h function was missing an output constraint for EDX which caused a register corruption to appear. As a result, Red Hat Enterprise Linux 3.8 and Red Hat Enterprise Linux 3.9 KVM guests with a Red Hat Enterprise Linux 6.1 KVM host kernel exhibited time inconsistencies. With this update, the underlying source code has been modified to address this issue, and time runs as expected on the aforementioned systems.
BZ#712000
Prior to this update, the following message appeared in kernel log files:
[bnx2x_extract_max_cfg:1079(eth11)]Illegal configuration detected for Max BW - using 100 instead
The above message appeared on bnx2x interfaces in the multi-function mode which were not used and had no link, thus, not indicating any actual problems with connectivity. With this update, the message has been removed and no longer appears in kernel log files.
BZ#713730
Previously, some enclosure devices with a broken firmware reported incorrect values. As a consequence, kernel sometimes terminated unexpectedly. A patch has been provided to address this issue, and the kernel crashes no longer occur even if an enclosure device reports incorrect or duplicate data.
BZ#709856
Xen guests cannot make use of all CPU features, and in some cases they are even risky to be advertised. One such feature is CONSTANT_TSC. This feature prevents the TSC (Time Stamp Counter) from being marked as unstable, which allows the sched_clock_stable option to be enabled. Having the sched_clock_stable option enabled is problematic for Xen PV guests because the sched_clock() function has been overridden with the xen_sched_clock() function, which is not synchronized between virtual CPUs. This update provides a patch, which sets all x86_power features to 0 as a preventive measure against other potentially dangerous assumptions the kernel could make based on the features, fixing this issue.
BZ#623712
RHEL6.2 backported the scalability improvement on creating many 'cpu' control groups (cgroups) on a system with a large number of CPUs. The creation process for large number of cgroups will no longer hog the machine when the control groups feature is enabled.
In addition to the scalability improvement, a /proc tunable parameter, dd sysctl_sched_shares_window, has been added, and the default is set to 10 ms.
BZ#719304
Older versions of be2net cards firmware may not recognize certain commands and return illegal/unsupported errors, causing confusing error messages to appear in the logs. With this update, the driver handles these errors gracefully and does not log them.
BZ#722461
On IBM System z, if a Linux instance with large amounts of anonymous memory runs into a memory shortage the first time, all pages on the active or inactive lists are considered referenced. This causes the memory management on IBM System z to do a full check over all page cache pages and start writeback for all of them. As a consequence, the system became temporarily unresponsive when the described situation occurred. With this update, only pages with active mappers are checked and the page scan now does not cause the hangs.
BZ#722596
This update fixes the inability of the be2net driver to work in a kdump environment. It clears an interrupt bit (in the card) that may be set while the driver is probed by the kdump kernel after a crash.
BZ#705441
A previously introduced update intended to prevent IOMMU (I/O Memory Management Unit) domain exhaustion introduced two regressions. The first regression was a race where a domain pointer could be freed while a lazy flush algorithm still had a reference to it, eventually causing kernel panic. The second regression was an erroneous reference removal for identity mapped and VM IOMMU domains, causing I/O errors. Both of these regressions could only be triggered on Intel based platforms, supporting VT-d, booted with the intel_iommu=on boot option. With this update, the underlying source code of the intel-iommu driver has been modified to resolve both of these problems. A forced flush is now used to avoid the lazy use after free issue, and extra checks have been added to avoid the erroneous reference removal.
BZ#635596
This update fixes two bugs related to Rx checksum offloading. These bugs caused a data corruption transferred over r8169 NIC when Rx checksum offloading was enabled.
BZ#704401
Prior to this update, kdump failed to create a vmcore file after triggering a crash on POWER7 systems with Dynamic DMA Windows enabled. This update provides a number of fixes that address this issue.
BZ#703935
Previously, auditing system calls used a simple check to determine whether a return value was positive or negative, which also determined the success of the system call. With an exception of few, this worked on most platforms and with most system calls. For example, the 32 bit mmap system call on the AMD64 architecture could return a pointer which appeared to be of value negative even though pointers are normally of unsigned values. This resulted in the success field being incorrect. This patch fixes the success field for all system calls on all architectures.
BZ#703245
When VLANs stacked on top of multiqueue devices passed through these devices, the queue_mapping value was not properly decremented because the VLAN devices called the physical devices via the ndo_select_queue method. This update removes the multiqueue functionality, resolving this issue.
BZ#703055
Prior to this update, Red Hat Enterprise Linux Xen (up to version 5.6) did not hide 1 GB pages and RDTSCP (enumeration features of CPUID), causing guest soft lock ups on AMD hosts when the guest's memory was greater than 8 GB. With this update, a Red Hat Enterprise Linux 6 HVM (Hardware Virtual Machine) guest is able to run on Red Hat Enterprise Linux Xen 5.6 and lower.
BZ#702742
Prior to this update, code was missing from the netif_set_real_num_tx_queues() function which prevented an increment of the real number of TX queues (the real_num_tx_queues value). This update adds the missing code; thus, resolving this issue.
BZ#725711
Previously, the inet6_sk_generic() function was using the obj_size variable to compute the address of its inner structure, causing memory corruption. With this update, the sk_alloc_size() is called every time there is a request for allocation, and memory corruption no longer occurs.
BZ#702057
Multiple GFS2 nodes attempted to unlink, rename, or manipulate files at the same time, causing various forms of file system corruption, panics, and withdraws. This update adds multiple checks for dinode's i_nlink value to assure inode operations such as link, unlink, or rename no longer cause the aforementioned problems.
BZ#701951
A kernel panic in the mpt2sas driver could occur on an IBM system using a drive with SMART (Self-Monitoring, Analysis and Reporting Technology) issues. This was because the driver was sending an SEP request while the kernel was in the interrupt context, causing the driver to enter the sleep state. With this update, a fake event is not executed from the interrupt context, assuring the SEP request is properly issued.
BZ#700538
When using certain SELinux policies, such as the MLS policy, it was not possible to properly mount the cgroupfs file system due to the way security checks were applied to the new cgroupfs inodes during the mount operation. With this update, the security checks applied during the mount operation have been changed so that they always succeed, and the cgroupfs file system can now be successfully mounted and used with the MLS SELinux policy. This issue did not affect systems which used the default targeted policy.
BZ#729220
When a SCTP (Stream Control Transmission Protocol) packet contained two COOKIE_ECHO chunks and nothing else, the SCTP state machine disabled output processing for the socket while processing the first COOKIE_ECHO chunk, then lost the association and forgot to re-enable output processing for the socket. As a consequence, any data which needed to be sent to a peer were blocked and the socket appeared to be unresponsive. With this update, a new SCTP command has been added to the kernel code, which sets the association explicitly; the command is used when processing the second COOKIE_ECHO chunk to restore the context for SCTP state machine, thus fixing this bug.
BZ#698268
The hpsa driver has been updated to provide a fix for hpsa driver kdump failures.
BZ#696777
Prior to this update, interrupts were enabled before the dispatch log for the boot CPU was set up, causing kernel panic if a timer interrupt occurred before the log was set up. This update adds a check to the scan_dispatch_log function to ensure the dispatch log has been allocated.
BZ#696754
Prior to this update, the interrupt service routine was performing unnecessary MMIO operation during performance testing on IBM POWER7 machines. With this update, the logic of the routine has been modified so that there are fewer MMIO operations in the performance path of the code. Additionally, as a result of the aforementioned change, an existing condition was exposed where the IPR driver (the controller device driver) could return an unexpected HRRQ (Host Receive Request) interrupt. The original code flagged the interrupt as unexpected and then reset the adapter. After further analysis, it was confirmed that this condition could occasionally occur and the interrupt can be safely ignored. Additional code provided by this update detects this condition, clears the interrupt, and allows the driver to continue without resetting the adapter.
BZ#732706
The ACPI (Advanced Control and Power Interface) core places all events to the kacpi_notify queue including PCI hotplug events. When the acpiphp driver was loaded and a PCI card with a PCI-to-PCI bridge was removed from the system, the code path attempted to empty the kacpi_notify queue which causes a deadlock, and the kacpi_notify thread became unresponsive. With this update, the call sequence has been fixed, and the bridge is now cleaned-up properly in the described scenario.
BZ#669363
Prior to this update, the /proc/diskstats file showed erroneous values. This occurred when the kernel merged two I/O operations for adjacent sectors which were located on different disk partitions. Two merge requests were submitted for the adjacent sectors, the first request for the second partition and the second request for the first partition, which was then merged to the first request. The first submission of the merge request incremented the in_flight value for the second partition. However, at the completion of the merge request, the in_flight value of a different partition (the first one) was decremented. This resulted in the erroneous values displayed in the /proc/diskstats file. With this update, the merging of two I/O operations which are located on different disk partitions has been fixed and works as expected.
BZ#670765
Due to an uninitialized variable (specifically, the isr_ack variable), a virtual guest could become unresponsive when migrated while being rebooted. With this update, the said variable is properly initialized, and virtual guests no longer hang in the aforementioned scenario.
BZ#695231
Prior to this update, the be2net driver was using the BE3 chipset in legacy mode. This update enables this chipset to work in a native mode, making it possible to use all 4 ports on a 4-port integrated NIC.
BZ#694747
A Windows Server 2008 32-bit guest installation failed on a Red Hat Enterprise Linux 6.1 Snap2 KVM host when allocating more than one virtual CPU (vcpus > 1) during the installation. As soon the installation started after booting from ISO, a blue screen with the following error occurred:
A problem has been detected and windows has been shut down to prevent damage to your computer.
This was because a valid microcode update signature was not reported to the guest. This update fixes this issue by reporting a non-zero microcode update signature to the guest.
BZ#679526
Disk read operations on a memory constrained system could cause allocations to stall. As a result, the system performance would drop considerably. With this update, latencies seen in page reclaim operations have been reduced and their efficiency improved; thus, fixing this issue.
BZ#736667
A workaround to the megaraid_sas driver was provided to address an issue but as a side effect of the workaround, megaraid_sas stopped to report certain enclosures, CD-ROM drives, and other devices. The underlying problem for the issue has been fixed as reported in BZ#741166. With this update, the original workaround has been reverted, and megaraid_sas now reports many different devices as before.
BZ#694210
This update fixes a regression in which a client would use an UNCHECKED NFS CREATE call when an open system call was attempted with the O_EXCL|O_CREAT flag combination. An EXCLUSIVE NFS CREATE call should have been used instead to ensure that O_EXCL semantics were preserved. As a result, an application could be led to believe that it had created the file when it was in fact created by another application.
BZ#692167
A race between the FSFREEZE ioctl() command to freeze an ext4 file system and mmap I/O operations would result in a deadlock if these two operations ran simultaneously. This update provides a number of patches to address this issue, and a deadlock no longer occurs in the previously-described scenario.
BZ#712653
When a CPU is about to modify data protected by the RCU (Read Copy Update) mechanism, it has to wait for other CPUs in the system to pass a quiescent state. Previously, the guest mode was not considered a quiescent state. As a consequence, if a CPU was in the guest mode for a long time, another CPU had to wait a long time in order to modify RCU-protected data. With this update, the rcu_virt_note_context_switch() function, which marks the guest mode as a quiescent state, has been added to the kernel, thus resolving this issue.
BZ#683658
The patch that fixed BZ#556572 introduced a bug where the page lock was being released too soon, allowing the do_wp_page function to reuse the wrprotected page before PageKsm would be set in page->mapping. With this update, a new version of the original fix was introduced, thus fixing this issue.
BZ#738110
Due to the partial support of IPv6 multicast snooping, IPv6 multicast packets may have been dropped. This update fixes IPv6 multicast snooping so that packets are no longer dropped.
BZ#691310
While executing a multi-threaded process by multiple CPUs, page-directory-pointer-table entry (PDPTE) registers were not fully flushed from the CPU cache when a Page Global Directory (PGD) entry was changed in x86 Physical Address Extension (PAE) mode. As a consequence, the process failed to respond for a long time before it successfully finished. With this update, the kernel has been modified to flush the Translation Lookaside Buffer (TLB) for each CPU using a page table that has changed. Multi-threaded processes now finish without hanging.
BZ#738379
When a kernel NFS server was being stopped, kernel sometimes terminated unexpectedly. A bug has been fixed in the wait_for_completion_interruptible_timeout() function and the crashes no longer occur in the described scenario.
BZ#690745
Recent Red Hat Enterprise Linux 6 releases use a new naming scheme for network interfaces on some machines. As a result, the installer may use different names during an upgrade in certain scenarios (typically em1 is used instead of eth0 on new Dell machines). However, the previously used network interface names are preserved on the system and the upgraded system will still use the previously used interfaces. This is not the case for Yum upgrades.
BZ#740465
A scenario for this bug involves two hosts, configured to use IPv4 network, and two guests, configured to use IPv6 network. When a guest on host A attempted to send a large UDP datagram to host B, host A terminated unexpectedly. With this update, the ipv6_select_ident() function has been fixed to accept the in6_addr parameter and to use the destination address in IPv6 header when no route is attached, and the crashes no longer occur in the described scenario.
BZ#693894
Migration of a Windows XP virtual guest during the early stage of a boot caused the virtual guest OS to fail to boot correctly. With this update, the underlying source code has been modified to address this issue, and the virtual guest OS no longer fails to boot.
BZ#694358
This update adds a missing patch to the ixgbe driver to use the kernel's generic routine to set and obtain the DCB (Data Center Bridging) priority. Without this fix, applications could not properly query the DCB priority.
BZ#679262
In Red Hat Enterprise Linux 6.2, due to security concerns, addresses in /proc/kallsyms and /proc/modules show all zeros when accessed by a non-root user.
BZ#695859
Red Hat Enterprise Linux 6.0 and 6.1 defaulted to running UEFI systems in a physical addressing mode. Red Hat Enterprise Linux 6.2 defaults to running UEFI systems in a virtual addressing mode. The previous behavior may be obtained by passing the physefi kernel parameter.
BZ#695966
After receiving an ABTS response, the FCoE (Fibre Channel over Ethernet) DDP error status was cleared. As a result, the FCoE DDP context invalidation was incorrectly bypassed and caused memory corruption. With this update, the underlying source code has been modified to address this issue, and memory corruption no longer occurs.
BZ#696511
Suspending a system to RAM and consequently resuming it caused USB3.0 ports to not work properly. This was because a USB3.0 device configured for MSIX would, during the resume operation, incorrectly read its previous interrupt state. This would lead it to fall back to a legacy mode and appear unresponsive. With this update, the interrupt state is cached, allowing the driver to properly resume its previous state.
BZ#662666
Deleting the lost+found directory on a file system with inodes of size greater than 128 bytes and reusing inode 11 for a different file caused the extended attributes for inode 11 (which were set before a umount operation) to not be saved after a file system remount. As a result, the extended attributes were lost after the remount. With this update, inodes store their extended attributes under all circumstances.
BZ#698023
Prior to this update, in the __cache_alloc() function, the ac variable could be changed after cache_alloc_refill() and the following kmemleak_erase() function could receive an incorrect pointer, causing kernel panic. With this update, the ac variable is updated after the cache_alloc_refill() unconditionally.
BZ#698625
This update includes two fixes for the bna driver, specifically:
  • A memory leak was caused by an unintentional assignment of the NULL value to the RX path destroy callback function pointer after a correct initialization.
  • During a kernel crash, the bna driver control path state machine and firmware did not receive a notification of the crash, and, as a result, were not shut down cleanly.
BZ#700165
When an event caused the ibmvscsi driver to reset its CRQ, re-registering the CRQ returned H_CLOSED, indicating that the Virtual I/O Server was not ready to receive commands. As a consequence, the ibmvscsi driver offlined the adapter and did not recover. With this update, the interrupt is re-enabled after the reset so that when the Virtual I/O server is ready and sends a CRQ init, it is able to receive it and resume initialization of the VSCSI adapter.
BZ#700299
This update standardizes the printed format of UUIDs (Universally Unique Identifier)/GUIDs (Globally Unique Identifier) by using an additional extension to the %p format specifier (which is used to show the memory address value of a pointer).
BZ#702036
Prior to this update, the ehea driver caused a kernel oops during a memory hotplug if the ports were not up. With this update, the waitqueues are initialized during the port probe operation, instead of during the port open operation.
BZ#702263
While running gfs2_grow, the file system became unresponsive. This was due to the log not getting flushed when a node dropped its rindex glock so that another node could grow the file system. If the log did not get flushed, GFS2 could corrupt the sd_log_le_rg list, ultimately causing a hang. With this update, a log flush is forced when the rindex glock is invalidated; gfs2_grow completes as expected and the file system remains accessible.
BZ#703251
The Brocade BFA FC/FCoE driver was previously selectively marked as a Technology Preview based on the type of the adapter. With this update, the Brocade BFA FC/FCoE driver is always marked as a Technology Preview.
BZ#703265
The Brocade BFA FC SCSI driver (bfa driver) has been upgraded to version 2.3.2.4. Additionally, this update provides the following two fixes:
  • A firmware download memory leak was caused by the release_firmware() function not being called after the request_firmware() function. Similarly, the firmware download interface has been fixed and now works as expected.
  • During a kernel crash, the bfa I/O control state machine and firmware did not receive a notification of the crash, and, as a result, were not shut down cleanly.
BZ#704231
A previously released patch for BZ#625487 introduced a kABI (Kernel Application Binary Interface) workaround that extended struct sock (the network layer representation of sockets) by putting the extension structure in the memory right after the original structure. As a result, the prot->obj_size pointer had to be adjusted in the proto_register function. Prior to this update, the adjustment was done only if the alloc_slab parameter of the proto_register function was not 0. When the alloc_slab parameter was 0, drivers performed allocations themselves using sk_alloc and as the allocated memory was lower than needed, a memory corruption could occur. With this update, the underlying source code has been modified to address this issue, and a memory corruption no longer occurs.
BZ#705082
A scalability issue with KVM/QEMU was discovered in the idr_lock spinlock in the posix-timers code, resulting in excessive CPU resource usage. With this update, the underlying source code has been modified to address this issue, and the aforementioned spinlock no longer uses excessive amounts of CPU resources.
BZ#723650
When a NFS server returned more than two GETATTR bitmap words in response to the FATTR4_ACL attribute request, decoding operations of the nfs4_getfacl() function failed. A patch has been provided to address this issue and the ACLs are now returned in the described scenario.
BZ#707268
After hot plugging one of the disks of a non-boot 2-disk RAID1 pair, the md driver would enter an infinite resync loop thinking there was a spare disk available, when, in fact, there was none. This update adds an additional check to detect the previously mentioned situation; thus, fixing this issue.
BZ#707757
The default for CFQ's group_isolation variable has been changed from 0 to 1 (/sys/block/<device>/queue/iosched/group_isolation). After various testing and numerous user reports, it was found that having default 1 is more useful. When set to 0, all random I/O queues become part of the root cgroup and not the actual cgroup which the application is part of. Consequently, this leads to no service differentiation for applications.
BZ#691945
In error recovery, most SCSI error recovery stages send a TUR (Test Unit Ready) command for every bad command when a driver error handler reports success. When several bad commands pointed to a same device, the device was probed multiple times. When the device was in a state where the device did not respond to commands even after a recovery function returned success, the error handler had to wait for the commands to time out. This significantly impeded the recovery process. With this update, SCSI mid-layer error routines to send test commands have been fixed to respond once per device instead of once per bad command, thus reducing error recovery time considerably.
BZ#696396
Prior to this update, loading the FS-Cache kernel module would cause the kernel to be tainted as a Technology Preview via the mark_tech_preview() function, which would cause kernel lock debugging to be disabled by the add_taint() function. However, the NFS and CIFS modules depend on the FS-Cache module so using either NFS or CIFS would cause the FS-Cache module to be loaded and the kernel tainted. With this update, FS-Cache only taints the kernel when a cache is brought online (for instance by starting the cachefilesd service) and, additionally, the add_taint() function has been modified so that it does not disable lock debugging for informational-only taints.
BZ#703728
This update removes temporary and unneeded files that were previously included with the kernel source code.
BZ#632802
Previously removed flushing of MMU updates in the kmap_atomic() and kunmap_atomic() functions resulted in a dereference bug when processing a fork() under a heavy load. This update fixes page table entries in the kmap_atomic() and kunmap_atomic() functions to be synchronous, regardless of the lazy_mmu mode, thus fixing this issue.
BZ#746570
Previously fixed ABI issues in Red Hat Enterprise Linux 6.2 resulted in broken drivers that were built against the Red Hat Enterprise Linux 6.1 sources. This update adds padding to the net_device private structure so that the overruns resulting from an excessively-long pointer computed in the netdev_priv structure do not exceed the bounds of allocated memory.
BZ#737753
A previously introduced patch increased the value of the cpuid field from 8 to 16 bits. As a result, in some cases, modules built against the Red Hat Enterprise Linux 6.0 kernel source panicked when loaded into the new Red Hat Enterprise Linux 6.2 kernel. This update provides a patch which fixes this guaranteed backwards compatibility.
BZ#745253
KABI issues with additional fields in the "uv_blade_info" structure were discovered that prevented existing SGI modules from loading against the Red Hat Enterprise Linux 6.2 kernel. This update fixes the code in the "uv_blade_info" structure, and SGI modules load against the Red Hat Enterprise Linux 6.2 kernel as expected.
BZ#748503
Incorrect duplicate MAC addresses were being used on a rack network daughter card that contained a quad-port Intel I350 Gigabit Ethernet Controller. With this update, the underlying source code has been modified to address this issue, and correct MAC addresses are now used under all circumstances.
BZ#728676
Prior to this update, on certain HP systems, the hpsa and cciss drivers could become unresponsive and cause the system to crash when booting due to an attempt to read from a write-only register. This update fixes this issue, and the aforementioned crashes no longer occur.
BZ#693930
The cxgb4 driver never waited for RDMA_WR/FINI completions because the condition variable used to determine whether the completion happened was never reset, and this condition variable was reused for both connection setup and teardown. This caused various driver crashes under heavy loads because resources were released too early. With this update, atomic bits are used to correctly reset the condition immediately after the completion is detected.
BZ#710497
If a Virtual I/O server failed in a dual virtual I/O server multipath configuration, not all remote ports were deleted, causing path failover to not work properly. With this update, all remote ports are deleted so that path failover works as expected. For a single path configuration, the remote ports will enter the devloss state.
BZ#713868
When using the "crashkernel=auto" parameter and the "crashk_res.start" variable was set to 0, the existing logic automatically set the value of the "crashk_res.start" variable to 32M. However, to keep enough space in the RMO region for the first stage kernel on 64-bit PowerPC, the "crashk_res.start" should have been set to KDUMP_KERNELBASE (64M). This update fixes this issue and properly assigns the correct value to the "crashk_res.start" variable.
BZ#743959
Due to a delay in settling of the usb-storage driver, the kernel failed to report all the disk drive devices in time to Anaconda, when booted in Unified Extensible Firmware Interface (UEFI) mode. Consequently, Anaconda presumed that no driver disks were available and loaded the standard drivers. With this update, both Anaconda and the driver use a one second delay, all devices are enumerated and inspected for driver disks properly.
BZ#690129
Prior to this update, the remap_file_pages() call was disabled for mappings without the VM_CAN_NONLINEAR flag set. Shared mappings of temporary file storage facilities (tmpfs) had this flag set but the flag was not set for the shared mappings of the /dev/zero device or shared anonymous mappings. With this update, the code has been modified and the VM_CAN_NONLINEAR flag is set also on the shared mappings of the /dev/zero device and shared anonymous mappings.
BZ#694309
The NFS client iterates through individual elements of a vector and issues a write request for each element to the server when the writev() function is called on a file opened with the O_DIRECT flag. Consequently, the server commits each individual write to the disk before replying to the client and the request transfer for the NFS client to the NFS server causes performance problems. With this update, the larger I/Os from the client are submitted only if all buffers are page-aligned, each individual vector element is aligned and has multiple pages, and the total I/O size is less than wsize (write block size).
BZ#699042
Improper shutdown in the e1000e driver caused a client with Intel 82578DM Gigabit Ethernet PHY to ignore the Wake-on-LAN signal and attempt to boot the client failed. This update applies the upstream Intel patch which fixes the problem.
BZ#703357
The "ifconfig up" command allocates memory for Direct Memory Access (DMA) operations. The memory is released when the "ifconfig down" command is issued. Previously, if another "ifconfig up" command was issued after an ifconfig up/down session, it re-enabled the DMA operations before sending the new DMA memory address to the NIC and the NIC could access the DMA address allocated during the previous ifconfig up/down session. However, the DMA address was already freed and could be used by another process. With this update, the underlying code has been modified and the problem no longer occurs.
BZ#729737
The in-process I/O operations of the Chelsio iWARP (cxgb3) driver could attempt to access a control data structure, which was previously freed after a hardware error that disabled the offload functionality occurred. This caused the system to terminate unexpectedly. With this update, the driver delays the freeing of the data structure and the problem no longer occurs.
BZ#734509
Previously, the capabilities flag of the WHEA_OSC call was set to 0. This could cause certain machines to disable APEI (ACPI Platform Error Interface). The flag is now set to 1, which enables APEI and fixes the problem.
BZ#748441
Previously, the origin device was being read when overwriting a complete chunk in the snapshot. This led to a significant memory leak when using the dm-snapshot module. With this update, reading of the origin device is skipped, and the memory leak no longer occurs.
BZ#750208
When the user attempted to list the mounted GFS2 file systems, a kernel panic occurred. This happened if the file in the location which the user tried to list was at the same time being manipulated by using the "fallocate" command. With this update, page cache is no longer used; the block is zeroed out at allocation time instead. Now, a kernel panic no longer occurs.
BZ#749018
The queuecommand error-handling function could cause memory leaks or prevent the TUR command from finishing for SCSI device drivers that enabled the support for lockless dispatching (lockless=1). This happened because the device driver did not call the scsi_cmd_get_serial() function and the serial_number property of the command remained zero. Consequently, the SCSI command could not be finished or aborted as the error-handling function always returned success for "serial_number == 0". The check for the serial number has been removed and the SCSI command can be finished or aborted.
BZ#750583
A previous patch for the Ironlake graphics controller and memory controller hub (GMCH) with a workaround for Virtualization Technology for Directed I/O (VT-d) introduced recursive calls to the unmap() function. With this update, a flag, which prevents the recursion, was added to the call chain, which allows the called routines to prevent the recursion.

CVE-2010-3858, Moderate
Missing sanity checks were found in setup_arg_pages() in the Linux kernel. When making the size of the argument and environment area on the stack very large, it could trigger a BUG_ON(), resulting in a local denial of service.
CVE-2011-1598, CVE-2011-1748, Moderate
A missing validation check was found in the bcm_release() and raw_release() functions in the Linux kernel's Controller Area Network (CAN) implementation. This could allow a local, unprivileged user to cause a denial of service.
CVE-2011-1771, Moderate
The fix for Red Hat Bugzilla bug 656461, as provided in RHSA-2011:0542, introduced a regression in the cifs_close() function in the Linux kernel's Common Internet File System (CIFS) implementation. A local, unprivileged user with write access to a CIFS file system could use this flaw to cause a denial of service.

Security Fix
CVE-2011-1767, CVE-2011-1768, Moderate
It was found that the receive hook in the ipip_init() function in the ipip module, and in the ipgre_init() function in the ip_gre module, could be called before network namespaces setup is complete. If packets were received at the time the ipip or ip_gre module was still being loaded into the kernel, it could cause a denial of service.
CVE-2011-2479, Moderate
It was found that an mmap() call with the MAP_PRIVATE flag on "/dev/zero" would create transparent hugepages and trigger a certain robustness check. A local, unprivileged user could use this flaw to cause a denial of service.

Security Fixes
CVE-2011-1898, Important
Using PCI passthrough without interrupt remapping support allowed KVM guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Refer to Red Hat Bugzilla bug 715555 for details.
CVE-2011-2491, Important
Flaw in the client-side NLM implementation could allow a local, unprivileged user to cause a denial of service.
CVE-2011-2497, Important
Integer underflow in the Bluetooth implementation could allow a remote attacker to cause a denial of service or escalate their privileges by sending a specially-crafted request to a target system via Bluetooth.
CVE-2011-2517, Important
Buffer overflows in the netlink-based wireless configuration interface implementation could allow a local user, who has the CAP_NET_ADMIN capability, to cause a denial of service or escalate their privileges on systems that have an active wireless interface.
CVE-2011-2695, Important
Flaw in the way the maximum file offset was handled for ext4 file systems could allow a local, unprivileged user to cause a denial of service.
CVE-2011-1576, Moderate
Flaw allowed napi_reuse_skb() to be called on VLAN packets. An attacker on the local network could use this flaw to send crafted packets to a target, possibly causing a denial of service.
CVE-2011-1593, Moderate
Integer signedness error in next_pidmap() could allow a local, unprivileged user to cause a denial of service.
CVE-2011-2183, Moderate
Race condition in the memory merging support (KSM) could allow a local, unprivileged user to cause a denial of service. KSM is off by default, but on systems running VDSM, or on KVM hosts, it is likely turned on by the ksm/ksmtuned services.
CVE-2011-2213, Moderate
Flaw in inet_diag_bc_audit() could allow a local, unprivileged user to cause a denial of service.
CVE-2011-2689, Moderate
Flaw in the way space was allocated in the Global File System 2 (GFS2) implementation. If the file system was almost full, and a local, unprivileged user made an fallocate() request, it could result in a denial of service. Setting quotas to prevent users from using all available disk space would prevent exploitation of this flaw.
CVE-2011-1182, Low
Local, unprivileged users could send signals via the sigqueueinfo system call, with si_code set to SI_TKILL and with spoofed process and user IDs, to other processes. This flaw does not allow existing permission checks to be bypassed; signals can only be sent if your privileges allow you to already do so.
CVE-2011-1776, Low
Heap overflow in the EFI GUID Partition Table (GPT) implementation could allow a local attacker to cause a denial of service by mounting a disk containing crafted partition tables.
CVE-2011-2492, Low
Structure padding in two structures in the Bluetooth implementation was not initialized properly before being copied to user-space, possibly allowing local, unprivileged users to leak kernel stack memory to user-space.
CVE-2011-2495, Low
/proc/[PID]/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to gather confidential information, such as the length of a password used in a process.

CVE-2011-1746, Important
An integer overflow flaw in agp_allocate_memory() could allow a local user to cause a denial of service or escalate their privileges.
CVE-2011-1833, Moderate
A race condition flaw was found in the Linux kernel's eCryptfs implementation. A local attacker could use the mount.ecryptfs_private utility to mount (and then access) a directory they would otherwise not have access to. Note: To correct this issue, the RHSA-2011:1241 ecryptfs-utils update, which provides the user-space part of the fix, must also be installed.
CVE-2011-2484, Moderate
A denial of service flaw was found in the way the taskstats subsystem handled the registration of process exit handlers. A local, unprivileged user could register an unlimited amount of these handlers, leading to excessive CPU time and memory use.
CVE-2011-2496, Moderate
A flaw was found in the way mapping expansions were handled. A local, unprivileged user could use this flaw to cause a wrapping condition, triggering a denial of service.
CVE-2011-2521, Moderate
A flaw was found in the Linux kernel's Performance Events implementation. It could falsely lead the NMI (Non-Maskable Interrupt) Watchdog to detect a lockup and panic the system. A local, unprivileged user could use this flaw to cause a denial of service (kernel panic) using the perf tool.
CVE-2011-2723, Moderate
A flaw in skb_gro_header_slow() in the Linux kernel could lead to GRO (Generic Receive Offload) fields being left in an inconsistent state. An attacker on the local network could use this flaw to trigger a denial of service. GRO is enabled by default in all network drivers that support it.
CVE-2011-2918, Moderate

Security Fixes
CVE-2011-2699, Important
IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services.
CVE-2011-3191, Important
A signedness issue was found in the Linux kernel's CIFS (Common Internet File System) implementation. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted.
CVE-2011-4326, Important
A flaw was found in the way the Linux kernel handled fragmented IPv6 UDP datagrams over the bridge with UDP Fragmentation Offload (UFO) functionality on. A remote attacker could use this flaw to cause a denial of service.
CVE-2011-3188, Moderate
The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random.
CVE-2011-3353, Moderate
A buffer overflow flaw was found in the Linux kernel's FUSE (Filesystem in Userspace) implementation. A local user in the fuse group who has access to mount a FUSE file system could use this flaw to cause a denial of service.
CVE-2011-3359, Moderate
A flaw was found in the b43 driver in the Linux kernel. If a system had an active wireless interface that uses the b43 driver, an attacker able to send a specially-crafted frame to that interface could cause a denial of service.
CVE-2011-3363, Moderate
A flaw was found in the way CIFS shares with DFS referrals at their root were handled. An attacker on the local network who is able to deploy a malicious CIFS server could create a CIFS network share that, when mounted, would cause the client system to crash.
CVE-2011-3593, Moderate
A flaw was found in the way the Linux kernel handled VLAN 0 frames with the priority tag set. When using certain network drivers, an attacker on the local network could use this flaw to cause a denial of service.
CVE-2011-1162, Low
A flaw in the way memory containing security-related data was handled in tpm_read() could allow a local, unprivileged user to read the results of a previously run TPM command.
CVE-2011-1577, Low
A heap overflow flaw was found in the Linux kernel's EFI GUID Partition Table (GPT) implementation. A local attacker could use this flaw to cause a denial of service by mounting a disk that contains specially-crafted partition tables.
CVE-2011-2494, Low
The I/O statistics from the taskstats subsystem could be read without any restrictions. A local, unprivileged user could use this flaw to gather confidential information, such as the length of a password used in a process.
CVE-2011-2905, Low
It was found that the perf tool, a part of the Linux kernel's Performance Events implementation, could load its configuration file from the current working directory. If a local user with access to the perf tool were tricked into running perf in a directory that contains a specially-crafted configuration file, it could cause perf to overwrite arbitrary files and directories accessible to that user.

Bug Fixes

BZ#710609
Xen guests cannot make use of all CPU features, and in some cases they are even risky to be advertised. One such feature is CONSTANT_TSC. This feature prevents the TSC (Time Stamp Counter) from being marked as unstable, which allows the sched_clock_stable option to be enabled. Having the sched_clock_stable option enabled is problematic for Xen PV guests because the sched_clock() function has been overridden with the xen_sched_clock() function, which is not synchronized between virtual CPUs. This update provides a patch, which sets all x86_power features to 0 as a preventive measure against other potentially dangerous assumptions the kernel could make based on the features, fixing this issue.
BZ#712191
Issues for which a host had older hypervisor code running on newer hardware, which exposed the new CPU features to the guests, were discovered. This was dangerous because newer guest kernels (such as Red Hat Enterprise Linux 6) may have attempted to use those features or assume certain machine behaviors that it would not be able to process because it was, in fact, a Xen guest. One such place was the intel_idle driver which attempts to use the MWAIT and MONITOR instructions. These instructions are invalid operations for a Xen PV guest. This update provides a patch, which masks the MWAIT instruction to avoid this issue.
Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

4.112. kexec-tools

An updated kexec-tools package that fixes three security issues, various bugs, and adds several enhancements is now available for Red Hat Enterprise Linux 6.

kexec-tools allows a Linux kernel to boot from the context of a running kernel.
Security Fixes
CVE-2011-3588
Kdump used the Secure Shell (SSH) StrictHostKeyChecking=no option when dumping to SSH targets, causing the target kdump server's SSH host key not to be checked. This could make it easier for a man-in-the-middle attacker on the local network to impersonate the kdump SSH target server and possibly gain access to sensitive information in the vmcore dumps.
CVE-2011-3589
mkdumprd created initial RAM disk (initrd) files with world-readable permissions. A local user could possibly use this flaw to gain access to sensitive information, such as the private SSH key used to authenticate to a remote server when kdump was configured to dump to an SSH target.
CVE-2011-3590
mkdumprd included unneeded sensitive files (such as all files from the /root/.ssh/ directory and the host's private SSH keys) in the resulting initrd. This could lead to an information leak when initrd files were previously created with world-readable permissions.

Note

With this update, only the SSH client configuration, known hosts files, and the SSH key configured via the newly introduced sshkey option in /etc/kdump.conf are included in the initrd. The default is the key generated when running the service kdump propagate command, /root/.ssh/kdump_id_rsa.
Red Hat would like to thank Kevan Carstensen for reporting these issues.
Bug Fixes
BZ#681796
Kdump is a kexec based crash dumping mechanism for Linux. Root System Description Pointer (RSDP) is a data structure used in the ACPI programming interface. Kdump uses kexec to boot to a second kernel, the "dump-capture" or "crash kernel", when a dump of the system kernel's memory needs to be taken. On systems using Extensible Firmware Interface (EFI), attempting to boot a second kernel using kdump failed, the dump-capture kernel became unresponsive and the following error message was logged.
ACPI Error: A valid RSDP was not found
With this update, a new parameter, acpi_rsdp, has been added to the noefi kernel command. Now, if EFI is detected, a command is given to the second kernel, in the format, noefi acpi_rsdp=X, not to use EFI and simultaneously passes the address of RSDP to the second kernel. The second kernel now boots successfully on EFI machines.
BZ#693025
To reduce the size of the vmcore dump file, kdump allows you to specify an external application (that is, a core collector) to compress the data. The core collector was not enabled by default when dumping to a secure location via SSH. Consequently, if users had not specified an argument for core_collector in kdump.conf, when kdump was configured to dump kernel data to a secure location using SSH, it generated a complete vmcore, without removing free pages. With this update, the default core collector will be makedumpfile when kdump is configured to use SSH. As a result, the vmcore dump file is now compressed by default.
BZ#707805
Previously, the mkdumprd utility failed to parse the /etc/mdadm.conf configuration file. As a consequence, mkdumprd failed to create an initial RAM disk file system (initrd) for kdump crash recovery and the kdump service failed to start. With this update, mkdumprd has been modified so that it now parses the configuration file and builds initrd correctly. The kdump service now starts as expected.
BZ#708503
In order for Coverity to scan defects in downstream patches separately, it is necessary to make a clean raw build of the source code without patches. However, kexec-tools would not build without downstream patches. With this update, by adding a specified patch in kexec-tools spec file, kexec-tools can now be built from source in the scenario described.
BZ#709441
On 64-bit PowerPC-based systems with more than 1 TB of RAM, the kexec-tools utility terminated unexpectedly with a segmentation fault when kdump was started, thus preventing crash kernel capture. With this update, the problem has been fixed, kexec-tools no longer crashes, and kdump can now be used on a system with greater than 1 TB of physical memory.
BZ#719105
The mkdumprd utility creates an initial RAM disk file system (initrd) for use in conjunction with the booting of a second kernel within the kdump framework for crash recovery. Prior to this update, mkdumprd became unresponsive when the running kernel was not the same as the target kernel. With this update the problem has been fixed and mkdumprd no longer hangs in the scenario described.
BZ#731236
A regression caused the following erroneous error message to be displayed when kdump was setting up Ethernet network connections in order to reach a remote dump target:
sed: /etc/cluster_iface: No such file or directory
A patch has been applied to correct the problem and the error no longer occurs in the scenario described.
BZ#731394
During kdump start up, a check was made to see if the amount of RAM the currently running kernel was using was more than 70% of the amount of RAM reserved for kdump. If the memory in use was greater than 70% of the memory reserved, the following error message was displayed.
Your running kernel is using more than 70% of the amount of space you reserved for kdump, you should consider increasing your crashkernel reservation
Due to improvements in conserving memory in the kexec kernel the warning is no longer considered valid. This update removes the warning.
BZ#739050
Previously, if kexec-tools was installed and kdump was not running, installing the fence-agents package caused the following erroneous error message:
Non-fatal <unknown> scriptlet failure in rpm package
This update corrects the kexec-tools spec file and the erroneous error message no longer appears.
BZ#746207
Removing kexec-tools on IBM System z resulted in the following error, even though the package was successfully removed.
error reading information on service kdump: No such file or directory
With this update, changes have been made to the kexec-tools spec file and the erroneous error message no longer appears.
BZ#747233
When providing firmware at operating system install time, supplied as part of the Driver Update program (DUP), the installation completed successfully but the operating system would fail on reboot. An error message in the following format was displayed:
cp: cannot stat `/lib/firmware/*': No such file or directory
With this update, a check for the directory containing the DUP supplied firmware is made and the problem no longer occurs.
Enhancements
BZ#585332
With large memory configurations, some machines take a long time to dump state information when a kernel panic occurs. The cluster software sometimes forced a reboot before the dump completed. With this update, co-ordination between kdump and cluster fencing for long kernel panic dumps is added.
BZ#598067
A new configuration option in kdump.conf, force_rebuild, has been added. When enabled, this option forces the kdump init script to rebuild initrd every time the system starts, thus ensuring kdump has enough storage space on each system start-up.
BZ#725484
On x86, AMD64 & Intel 64 platforms kexec-tools now uses nr_cpus=1 rather than maxcpus=1 to save memory required by the second kernel. PowerPC platforms currently cannot handle this feature.
BZ#727892
A warning was added to use maxcpus=1 instead of nr_cpus=1 for older kernels (see the enhancement above).
BZ#734528
Kdump has been provided with an option so that memory usage can be logged in the second kernel at various stages for debugging memory consumption issues. The second kernel memory usage debugging capability can be enabled via the new kdump.conf debug_mem_level option.
BZ#740275, BZ#740277
With this update, kdump support for dumping core to ext4 file systems, and also to XFS file systems on data disks (but not the root disk) has been added.

Note

For XFS, the XFS layer product needs to be installed. Layered products are those not included by default in the base Red Hat Enterprise Linux operating system.
BZ#740278
With this update, kdump support for dumping core to Btrfs file systems has been added.

Note

BusyBox's "findfs" utility does not yet support Btrfs, so UUID/LABEL resolving does not work. Avoid using UUID/LABEL syntax when dumping core to Btrfs file systems. Btrfs itself is still considered experimental; refer to Red Hat Technical Notes.
BZ#748748
Kdump did not check the return code of the mount command. Consequently, when the command mount -t debugfs debug /sys/kernel/debug was issued in the kdump service script, if the file system was already mounted, the message returned was erroneously logged as an error message. With this update, the logic in the kdump service script has been improved and the kdump service script now functions as expected.
Users of kexec-tools should upgrade to this updated package, which contains backported patches to resolve these issues and add these enhancements.
An updated kexec-tools package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The kexec-tools package contains the /sbin/kexec binary and utilities that together form the user-space component of the kernel's kexec feature. The /sbin/kexec binary facilitates a new kernel to boot using the kernel's kexec feature either on a normal or a panic reboot. The kexec fastboot mechanism allows booting a Linux kernel from the context of an already running kernel.

Bug Fixes

BZ#719917
Previously, the mkdumprd utility failed to parse the /etc/mdadm.cof configuration file. As a consequence, mkdumprd failed to create an initial ramdisk for kdump crash recovery and the kdump service failed to start. With this update, mkdumprd has been modified so that it now parses the configuration file and builds initrd correctly. The kdump service now starts as expected.
BZ#726603
On the PowerPC 64 architecture, the kexec utiliity experienced a segmentation fault when the kdump service was started on a system containing more than 1 TB of RAM. As a result, it was not possible to capture a crash kernel on such a system. This has been fixed with this update so that kexec no longer crashes when kdump starts on a system with greater than 1 TB of physical memory, and kdump can now works as expected.
All users of kexec-tools are advised to upgrade to this updated package, which fixes these bugs.

4.113. keyutils

Updated keyutils packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.
The keyutils package provides utilities to control the Linux kernel key management facility and to provide a mechanism by which the kernel calls up to user space to get a key instantiated.

Bug Fix

BZ#730002
The keyutils subpackage did not contain a dependency on the keyutils-libs subpackage but rather it contained only an implicit dependency on the libkeyutils.so.[n] shared object files specified as the SONAME variable. As a consequence, the keyutils subpackage could have been updated without applying the newest keyutils libraries, which could have caused keyutils to work incorrectly. To fix this issue, the keyutils spec file has been modified to include an explicit dependency on the version of keyutils-libs that matches the keyutils subpackage. Both subpackages are now updated together.

Enhancement

BZ#727280
Previously, the keyutils subpackages were compiled without the RELRO (read-only relocations) flag. Programs provided by this package and also programs built against the keyutils libraries were thus vulnerable to various attacks based on overwriting the ELF section of a program. To increase the security of keyutils programs and libraries, the keyutils spec file has been modified to use the "-Wl,-z,relro" flags when compiling the packages. As a result, the keyutils subpackages are now provided with partial RELRO protection.
Users are advised to upgrade to these updated keyutils packages, which fix this bug and add this enhancement.

4.114. krb5

Updated krb5 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

Updated krb5 packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
The Kerberos authentication system allows clients and servers to authenticate to each other using symmetric encryption and the help of a trusted third party, the KDC.
Bug Fixes
BZ#651466
Kerberos version 1.8 and later defaults to disabling support for older encryption types which are no longer believed to be sufficiently strong. When upgrading from older versions of Red Hat Enterprise Linux, a number of services which run at the key distribution center (KDC) need to have their keys reset to include keys for newer encryption types. This update adds a spot-check to the KDC init script which assist in diagnosing this condition.
BZ#701446,BZ#746341
Previously, a client could fail to connect to a KDC if a sufficiently large number of descriptors was already in use. This update modifies the Kerberos libraries to switch to using poll() instead of select(), which does not suffer from this limitation.
BZ#713252,BZ#729068
Previously, the kadmin client could fail to establish a connection with certain older versions of the kadmin daemon. In these situations, the server often logged a diagnostic noting that the client had supplied it with incorrect channel bindings. This update modifies the client to allow it to once again contact those versions of kadmind.
BZ#713518
Previously, a client failed to obtain credentials for authentication from KDCs that rejected requests specifying unrecognized options and that also did not support the canonicalize option. With this update, obtaining credentials also works with these KDCs.
BZ#714217
Previously, locally-applied patches, which attempt to ensure that any files created by the Kerberos libraries are given and keep the correct SELinux file labels, did not correctly ensure that replay cache files kept their labels. This update corrects the patch to cover this case.
BZ#717378
Previously, the Kerberos client libraries could inadvertently trigger an address-to-name lookup inside of the resolver libraries when attempting to derive a principal name from a combination of a service name and a host name, even if the user disabled them using the "rdns" setting in the krb5.conf file. This update modifies the client library to prevent it from triggering these lookups.
BZ#724033
Previously, the kadmind init script could erroneously refuse to start the kadmind server on a KDC, if the realm database was moved to a non-default location, or a non-default kdb backend was in use. This update removes the logic from the init script which caused it to do so.
BZ#729044
Previously, the krb5-debuginfo package excluded several source files used to build the package. This update ensures that the affected files are still included.
BZ#734341
Previously, obtaining the Kerberos credentials for services could fail fail if the target server was in another trusted realm than the client. This update modifies krb5-libs so that the client obtains the credentials as expected.
All Kerberos users are advised to upgrade to these updated packages, which fix these bugs.
Updated krb5 packages that fixes a bug is now available for Red Hat Enterprise Linux 6.
Kerberos is a network authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, a KDC (Key Distribution Center).

Bug Fix

BZ#714866
Certain versions of the KDC software (included for example in Red Hat Enterprise Linux 2.1 and 3) reject requests, which include KDC options the software does not recognize, and do not support the "canonicalize" option. When a client was configured to use one of these versions of the KDC software, the client failed to obtain credentials for authentication to other services. This interoperability regression was introduced in the update to Red Hat Enterprise Linux 6.1. With this update, an upstream patch has been provided to fix this bug.
Users of krb5 are advised to upgrade to these updated packages, which fix this bug.

4.115. krb5-appl

Updated krb5-appl packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The krb5-appl packages provide Kerberos-aware telnet, ftp, rcp, rsh, and rlogin clients and servers. While these have been replaced by tools such as OpenSSH in most environments, they remain in use in others.
Security Fix
CVE-2011-1526
It was found that gssftp, a Kerberos-aware FTP server, did not properly drop privileges. A remote FTP user could use this flaw to gain unauthorized read or write access to files that are owned by the root group.
Red Hat would like to thank the MIT Kerberos project for reporting this issue. Upstream acknowledges Tim Zingelman as the original reporter.
All krb5-appl users should upgrade to these updated packages, which contain a backported patch to correct this issue.

The krb5-appl packages contain Kerberos-aware versions of clients and servers for the telnet, FTP, rsh, and rlogin protocols.

Bug Fixes

BZ#713459
Prior to this update, the default PAM configuration for the FTP server incorrectly attempted to use the pam_selinux.so module. As a result, users failed to log in. This update corrects the supplied configuration. Now, the FTP server works as expected.
BZ#713521
Prior to this update, the FTP server did not correctly parse lines in the /etc/ftpusers file which specified user names in combination with the "restrict" keyword. This update modifies the code so that the server parses the "restrict" keyword correctly.

Enhancement

BZ#665834, BZ#736364
Prior to this update, the command-line FTP client in the krb5-appl-clients package did not accept command lines longer than 500 characters. This update removes this limitation.
All users of krb5-appl are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

4.116. ksh

An updated ksh package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
KSH-93 is the most recent version of the KornShell by David Korn of AT&T Bell Laboratories. KornShell is a shell programming language which is also compatible with sh, the original Bourne Shell.

Bug Fixes

BZ#702016
Previously, ksh did not always wait for a pipeline to complete when the pipefail option was used. Consequently, a failed exit status was erroneously reported even when the pipeline had not failed. With this update, the code has been improved and the pipefail option now functions as expected.
BZ#702013, BZ#728900
When running a ksh script the exit code of a child process was not preserved. Consequently, when a script asked for such an exit code, the wrong value was reported. With this update, an upstream patch has been applied which fixes the problem.
BZ#702015
File name completion used after an environment variable failed and ksh reported a "bad substitution" error. With this update, an upstream patch has been applied which fixes the problem.
BZ#702011
In POSIX functions, a function defined without using the, "function", keyword, the value of the variable "$0" was changed to the name of the function instead of keeping the original value, the name of the caller function. With this update an upstream patch has been applied to correct the code and ksh keeps the name of the caller function in "$0" as expected.
BZ#701890
Previously, when the ksh built-in "kill" command was called with a very large, non-existent PID value, it was interpreted as " -1". The "-1" argument to the kill command is for terminating all processes. Consequently, all processes owned by the user were killed. With this update a patch has been applied and ksh now checks for a valid process ID.
BZ#683734
If the IFS variable was unset inside a function used in a script, the memory being used was erroneously freed. Consequently, ksh would terminate unexpectedly. With this update, an upstream patch has been applied which still allows the IFS variable to be unset, but no longer frees the memory. Thus the problem is fixed, and ksh no longer crashes in the scenario described.
BZ#702014
Previously, ksh treated an array declaration as a definition. Consequently, the array contained one element after the declaration. This bug has been fixed, and now an array is correctly reported as empty after a declaration.
BZ#742244
Previously, when using ksh, ksh became unresponsive when pipes were used in a "eval" argument. With this update an upstream patch has been applied and the ksh no longer hangs in the scenario described.
BZ#743842
ksh could return the exit code of the previous process to have used the same PID number, when PID numbers were being reused after many hundreds of iterations of a script. With this update the code has been fixed and the error no longer occurs in the scenario described.
All users of ksh are advised to upgrade to this updated package, which fixes these bugs.

4.117. less

An updated less package that fixes two bugs and adds one enhancement is now available for Red Hat Enterprise Linux 6.
The less package contains a text file browser that is similar to the more browser, but with more features ("less is more"). The less text file browser allows users to move backwards in the file as well as forwards. Because the less utility does not need to read the entire input file before it starts, it starts up faster than text editors.

Bug Fixes

BZ#644858
Prior to this update, the online help for the less utility contained incorrect descriptions for several options. With this update, the descriptions have been corrected and the online help describes now all options correctly.
BZ#729025
Prior to this update, a debuginfo file for a binary was missing from the less-debuginfo package. As a result, the crash analysis via the Automatic Bug-Reporting Tool (ABRT) did not work as expected and debugging via GNU Debugger (GDB) could fail. This update modifies the spec file so that the crash analysis via ABRT and debugging via GDB work as expected.

Enhancement

BZ#718498
Prior to this update, the less utility could not view its compressed .xz files.This update adds support for .xz files to lesspipe.sh.
All users of the less text file browser are advised to upgrade to this updated package, which fixes these bugs and adds this enhancement.

4.118. libarchive

Updated libarchive packages that fix two security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The libarchive programming library can create and read several different streaming archive formats, including GNU tar and cpio. It can also read ISO 9660 CD-ROM images.
Security Fixes
CVE-2011-1777, CVE-2011-1778
Two heap-based buffer overflow flaws were discovered in libarchive. If a user were tricked into expanding a specially-crafted ISO 9660 CD-ROM image or tar archive with an application using libarchive, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
All libarchive users should upgrade to these updated packages, which contain backported patches to correct these issues. All running applications using libarchive must be restarted for this update to take effect.

4.119. libcacard

Updated libcacard and spice-client packages that fix a number of bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The Simple Protocol for Independent Computing Environments (SPICE) is a remote display protocol designed for virtual environments. The spice-client package provides the client side of the SPICE protocol.
The libcacard package contains the Common Access Card (CAC) emulation library.
BZ#723687
The spice-client package has been upgraded to upstream version 0.8.2, which provides a number of bug fixes and enhancements over the previous version, including:
  • Various code cleanup modifications, such as removing unused variables, dead code and typos, have been included.
  • Several package build changes, such as enabling a silent build and a cleanup in the configure.ac script have been included.
  • White spaces in values for the --host-subject command line option are now ignored.
  • A new --version command line option for the spicec command has been added.
BZ#723895
The libcacard package has been upgraded to upstream version 0.15.0, which provides a number of bug fixes and enhancements over the previous version, including a fix for the following bug:
  • Some AET middleware did not work correctly with the CKM_RSA_X_590 encrypting mechanism even though it reported support for this mechanism. Consequently, if such middleware was used by libcacard virtual smart cards, smart cards failed to emulate any RSA authentication based operations, such as requesting a security pin or retrieving user certificates. The library has been modified to handle CKM_RSA_X590 failures by falling back to use CKM_RSA_PKCS encryption. Virtual smart cards now work correctly with AET middleware.
Bug Fixes
BZ#707122
Although old SPICE-related packages (such as cairo-spice) are no longer required to be installed with the spice-client package, they were still needed by a previously installed spice-client or spice-server package. With the Obsolete lines in the package spec file, updating spice-client forced an update of spice-server as well, and vice versa. With this update, all "Obsolete" lines have been removed from the spice-client.spec file, and updating spice-client no longer forces the update of spice-server.
BZ#692976
The SPICE client did not correctly handle monitor setting routines when it was running on a client machine with multiple monitors. As a consequence, the client entered an infinite loop while trying to rearrange monitors, which eventually caused the client to terminate unexpectedly. With this update, the code has been modified to prevent the client from entering this loop, and the client thus no longer crashes.
BZ#725009
The SPICE client failed to connect to the SPICE server on the target host after a virtual machine had been migrated to a remote machine. This happened when the migration of the virtual machine took longer than the expiration time of the SPICE ticket that was set on the target host. Without a valid password, the SPICE server refused connection from the SPICE client and the SPICE session had to be closed. To prevent this problem, support for spice semi-seamless migration has been added. Other components such as spice-protocol, spice-server and qemu-kvm have also been modified to support this feature. SPICE now allows the SPICE client to connect to the SPICE server on the target host at the very start of the virtual machine migration, just before the migrate monitor command is given to the qemu-kvm application. With a valid ticket on the target host, the SPICE ticket on the destination no longer expires and the SPICE client now remains open when the virtual machine migration is done.
BZ#710461
Due to an incorrect condition in the code, the SPICE client could attempt to free memory that has already been freed. Therefore, when the KDE desktop screen of the client machine with the running SPICE client was locked, the SPICE client terminated unexpectedly with a segmentation fault after unlocking the screen. The code has been modified to free memory correctly, and the SPICE client no longer crashes in the scenario described.
BZ#692833
When running multiple SPICE client sessions at the same time and the screen resolution on the client machine was changed, the SPICE client could often enter an infinite loop in the code. As a consequence, the X Windows server consumed up to 100% of CPU and caused the client machine to be unresponsive. With this update, the underlying code has been modified to prevent the client from entering the loop, and the problem no longer occurs.
BZ#712941
The help description for the --color-depth and --disable-effects client WAN options was inaccurate. With this update, the spicec --help command now clearly states that these WAN options have effect only if supported by the guest vdagent.
BZ#653545
Due to the way the SPICE server establishes secured connections, the SPICE client log contained secure-connection messages that included the misleading string, connect_unsecure. With this update, the function used to establish secure connections has been renamed and secure-connection messages in the client log now contain the connect_to_peer string.
BZ#732423
On a Linux guest that uses the Xinerama extension, X Windows creates a non-primary screen surface before it creates the primary screen surface when creating secondary screens on start up. Unfortunately, the SPICE client expected an existence of the primary screen surface when it attempted to handle the creation of non-primary screen surfaces. The primary surface did not exist at the time, therefore the SPICE client terminated unexpectedly. With this update, the SPICE client now ensures that the screen exists before starting operations on it. The SPICE client no longer crashes in the scenario described.
BZ#723567
Previously, the --smartcard-db client command line option was not handled properly. As a consequence, when running with this option, the SPICE client terminated with the following error message:
Error: unhandled exception: cmd line error
With this update, the --smartcard-db option is now handled properly and the SPICE client works as expected using this option.
BZ#712938
When attempting to connect to a Linux guest using the SPICE client with WAN options and the SPICE agent (vdagent) was running on the guest, the client initiated handshaking. If the vdagent did not support WAN options, it did not reply to the client and connection thus failed with the vdagent timeout. Also with certain WAN options, such as --color-depth 16, the attempt to connect failed with the vdagent timeout even though no vdagent was running on the guest. With this update, the SPICE client checks capabilities of the vdagent. If vdagent does not support WAN options or there is no vdagent running on the guest, the client continues with the message sequence initiation and connection is now successful.
BZ#696964
Due to a missing error code setting in the source code, the SPICE client returned exit code 0 when running without the --host command line option, although the client correctly displayed the following error message:
spicec: missing --host
With this update, the missing line in the code has been added, and the SPICE client now correctly exits with the error code 14 in this scenario.
All users of libcacard and spice-client are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.

4.120. libcap

Updated libcap packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The libcap packages provide a library and tools for getting and setting POSIX capabilities.
Security Fix
CVE-2011-4099
It was found that capsh did not change into the new root when using the "--chroot" option. An application started via the "capsh --chroot" command could use this flaw to escape the chroot restrictions.

Bug Fix

BZ#730957
Previously, the libcap packages did not contain the capsh(1) manual page. With this update, the capsh(1) manual page is included.
All libcap users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

4.121. libcgroup

An updated libcgroup package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The libcgroup package provides tools and libraries to control and monitor control groups.

Bug Fix

BZ#715413
Prior to this update, when installing the libcgroup package, a new group "cgred" was erroneously created as a user group (starting with GID 500) and not as a system group (with GID lower than 500). As a result, newly created users could have had UID different to GID. With this update, the "cgred" group is now created correctly as the system group with GID lower than 500. This update does not change GID of the "cgred" group if the group already exists on the system.
All users are advised to upgrade to this updated libcgroup package, which fixes this bug.

4.122. libcmpiutil

An updated libcmpiutil package that adds one enhancement is now available for Red Hat Enterprise Linux 6.
The libcmpiutil library provides an application programming interface (API) for performing common tasks with various Common Manageability Programming Interface (CMPI) providers.

Enhancement

BZ#694550
With this update, the performance and the interface of the libcmpiutil library have been enhanced, which is used by the libvirt-cim package.
All libcmpiutil users are advised to upgrade to this updated package, which adds this enhancement.

4.123. libesmtp

An updated libesmtp package that adds one enhancement is now available for Red Hat Enterprise Linux 6.
LibESMTP is a library to manage posting or submitting electronic mail using SMTP to a preconfigured Mail Transport Agent (MTA). The libesmtp package is required by Open MPI.

Enhancement

BZ#738760
Previously, LibESMTP was not shipped with Red Hat Enterprise Linux 6 on the 64-bit PowerPC platform. This update adds the LibESMTP package to the 64-bit PowerPC variant, as a requirement of the updated OpenMPI. Note, that this update does not contain any changes for other architectures.
All users requiring libesmtp on the 64-bit PowerPC architecture are advised to install this package, which adds this enhancement.

4.124. libgcrypt

An updated libgcrypt package that add an enhancement is now available for Red Hat Enterprise Linux 6.
The libgcrypt package contains a library which provides general-purpose implementations of various cryptographic algorithms.

Enhancement

BZ#727283
With this update, the libgcrypt library has been recompiled with read-only relocation support that improves the security vulnerability properties of applications that use the library.
All users of libgcrypt are advised to upgrade to this updated package, which adds this enhancement.
An updated libgcrypt package that adds an enhancement is now available for Red Hat Enterprise Linux 6.
The libgcrypt library provides general-purpose implementations of various cryptographic algorithms.

Enhancement

BZ#709059
With this update, the libgcrypt API for the DSA algorithm has been enhanced to allow for presetting the prime (P) and the subprime (Q) parameters when generating the base (G) parameter. This is necessary for the algorithm correctness validation according to the FIPS-186-3 standard.
All users of libgcrypt are advised to upgrade to this updated package, which adds this enhancement.
An updated libgcrypt package that introduces a feature enhancement is now available for Red Hat Enterprise Linux 6.
The libgcrypt library provides general-purpose implementations of various cryptographic algorithms.

Enhancement

BZ#703490
In FIPS mode, libgcrypt can now use a configurable source of RNG (Random Number Generator) seed. On systems with sufficient amount of entropy gathered from the kernel entropy sources or systems with hardware RNGs, the system administrator can add the "/etc/gcrypt/rngseed" symbolic link pointing to the "/dev/random" device node or a hardware RNG device. This symbolic link will be then opened and read by the libgcrypt library to initialize its RNG.
All users of libgcrypt are advised to upgrade to this updated package, which adds this enhancement.

4.125. libgpg-error

An updated libgpg-error package is now available for Red Hat Enterprise Linux 6.
The libgpg-error library provides a set of common error codes and definitions which are shared by the gnupg, libgcrypt and other packages.

Enhancement

BZ#727287
Previously, the libgpg-error package was compiled without the RELRO (read-only relocations) flag. Programs provided by this package were thus vulnerable to various attacks based on overwriting the ELF section of a program. To increase the security of the libgpg-error library, the libgpg-error spec file has been modified to use the "-Wl,-z,relro" flags when compiling the package. As a result, the libgpg-error package is now provided with partial RELRO protection.
Users of libgpg-error are advised to upgrade to this updated package, which adds this enhancement.

4.126. libguestfs

Updated libguestfs packages that fix multiple bugs and add one enhancement are now available for Red Hat Enterprise Linux 6.
The libguestfs packages contain a library, which is used for accessing and modifying guest disk images.
Bug Fixes
BZ#603000
Previously, the do_part_get_bootable() API function parsed the output of parted with an assumption that the partition layout on the guest image was well ordered. As a consequence, the part-get-bootable API would produce an incorrect result or even terminate with disks where the partitions were not in the usual order or were missing. With this update, the source code is modified so that libuguestfs can correctly handle disks with unordered partitions.
BZ#627835
Previously, libguestfs protocol lost synchronization when using the upload command in the guestfish command line tool before mounting any disks. Uploading files failed and an error message was reported due to the library and the daemon sending cancel messages in an incorrect order. With this update, if the daemon detects cancellation, it sends the remaining data in its output buffer instead of discarding it.
BZ#666578, BZ#678231
Previously, if guests used the LABEL or UUID (Universal Unique Identifier) identifiers for swap devices in the guest /etc/fstab file, the virt-inspector utility reported the unknown filesystem error message. The source code has been modified, and the utility now works correctly and no longer displays error messages.
BZ#682980
Prior to this update, libguestfs could have incorrectly detected Red Hat Enterprise Linux Desktop distributions as a "redhat-based" instead of "redhat". As a consequence, the virt-v2v utility failed to convert such guests. With this update, libguestfs is modified to detect these distributions correctly as "redhat". Now, conversion is successful.
BZ#684980
Calling the guestfs_kill_subprocess() function and then closing the connection handle by calling guestfs_close() could cause the libguestfs connection to become unresponsive. The source code has been modified to close the connection correctly so that the connections no longer hangs.
BZ#685009
After the resize operation, the ntfsresize utility marks the file system as requiring a consistency check. As a consequence, an error message can appear when resizing the same file system multiple times in a row without rebooting the virtual machine. With this update, the ntfsresize(8) manual page describes this behavior.
BZ#688062
Previously, when pressing the tab key in the guestfish command line tool, the mapped devices created by luks-open were not listed. With this update, /dev/mapper/ paths are added to tab-completion and the devices are displayed when pressing the tab key.
BZ#690358
Querying a fully-virtualized guest works reliably only for Linux guests. With this update, the virt-inspector(1) manual page is modified to note this.
BZ#692394
Previously, the inspect-list-applications API and virt-inspector2 utility did not detect 32-bit applications installed under the WoW64 (Windows 32-bit on Windows 64-bit) emulator on a 64-bit Windows guest. With this update, the source code is modified to display the installed applications with their description in the output.
BZ#693306
Iterables passed instead of plain lists could cause the RuntimeError exception to be thrown when calling libguestfs' Python interface. The Python bindings have been modified so that any iterable argument can be used as a list.
BZ#695881
Previously, the virt-make-fs tool generated the qemu-img command which contained an incorrect decimal point in the output. As a result, an error message was reported. With this update, the source code is modified so that the virt-make-fs tool invokes qemu-img correctly in all cases.
BZ#713529
Due to incorrect mounting of guest file systems, the virt-v2v utility could fail when the guest /etc/fstab file contained file systems marked with LABEL. This update modifies the source code so that the file systems are mounted correctly. As a result, virt-v2v no longer fails.
BZ#725563
With this update, libguestfs is rebuilt against the latest parted package, which adds support for the Legacy BIOS Bootable flag in the GPT (GUID Partition Table) attribute field.
BZ#727178
Prior to this update, a build error prevented libguestfs from working on LUKS (Linux Unified Key Setup) encrypted disks. As a result, loading of shared libraries failed with an error message. An upstream patch has been applied to address this issue and libguestfs now works correctly on LUKS devices.
BZ#729887
This update adds the description of typecheck lenses in the guestfish(1) manual page.
BZ#730248
The guestfish(1) manual page has been modified to mention that guestfish --remote run should not be used in a command substitution context.
Enhancement
BZ#672491
Prior to this update, the guestfs_last_errno() function was not exposed in the Perl bindings. As a consequence, it was not directly possible to determine the precise cause of some failures. To fix this problem, guestfs_last_errno() is now exposed in the Perl bindings.
All users of libguestfs are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.

4.127. libhbaapi

An updated libhbaapi package that fixes multiple bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.

4.131. libnih

An updated libnih package that adds one enhancement is now available for Red Hat Enterprise Linux 6.
The libnih package includes a small library for C application development. The library is similar to other C libraries, such as glib.

Enhancement

BZ#727284
Previously, the libnih package was compiled without the read-only relocations (RELRO) flag. Programs built against the libnih library could be vulnerable to various attacks based on overwriting the ELF section of a program. To enhance the security, the libnih package is now provided with partial RELRO support.
All users of libnih are advised to upgrade to this updated package, which adds this enhancement.

4.132. libpng

Updated libpng packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The libpng packages contain a library of functions for creating and manipulating PNG (Portable Network Graphics) image format files.
Security Fixes
CVE-2011-2690
A buffer overflow flaw was found in the way libpng processed certain PNG image files. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash or, potentially, execute arbitrary code with the privileges of the user running the application.

Note

The application behavior required to exploit CVE-2011-2690 is rarely used. No application shipped with Red Hat Enterprise Linux behaves this way, for example.
CVE-2011-2501
An out-of-bounds memory read flaw was found in the way libpng processed certain PNG image files. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash.
CVE-2011-2692
An uninitialized memory read issue was found in the way libpng processed certain PNG images that use the Physical Scale (sCAL) extension. An attacker could create a specially-crafted PNG image that, when opened, could cause an application using libpng to crash.
Users of libpng should upgrade to these updated packages, which upgrade libpng to version 1.2.46 to correct these issues. All running applications using libpng must be restarted for the update to take effect.

4.133. librsvg2

Updated librsvg2 packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The librsvg2 packages provide an SVG (Scalable Vector Graphics) library based on libart.
Security Fix
CVE-2011-3146
A flaw was found in the way librsvg2 parsed certain SVG files. An attacker could create a specially-crafted SVG file that, when opened, would cause applications that use librsvg2 (such as Eye of GNOME) to crash or, potentially, execute arbitrary code.
Red Hat would like to thank the Ubuntu Security Team for reporting this issue. The Ubuntu Security Team acknowledges Sauli Pahlman as the original reporter.
All librsvg2 users should upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications that use librsvg2 must be restarted for this update to take effect.

4.134. libselinux

Updated libselinux packages that fix three bugs are now available for Red Hat Enterprise Linux 6.
The libselinux packages contain the core library of an SELinux system. The libselinux library provides an API for SELinux applications to get and set process and file security contexts, and to obtain security policy decisions. It is required for any applications that use the SELinux API, and used by all applications that are SELinux-aware.

Bug Fixes

BZ#698583
Prior to this update, Python bindings for the restorecon command required a user to specify the entire path. Consequent to this, an attempt to use the selinux.restorecon() function with a relative path failed with the following error message:
OSError: [Errno 2] No such file or directory
This update corrects the Python bindings to allow the use of the selinux.restorecon() function with a relative path or just a file name.
BZ#706049
Previously, the is_selinux_enabled() function may have incorrectly returned a positive value even when the machine was disabled. This happened when the same process that made the calls to disable SELinux attempted to determine if SELinux is enabled, because the selinux_mnt variable was not properly freed and still contained old data. With this update, a patch has been applied to make sure the selinux_mnt variable is now properly freed, and the is_selinux_enabled() function works as expected.
BZ#748471
When a semanage login record was set up using a group name and the number of elements in the group was too large, login programs failed to log in the user with the correct context. This update corrects the libselinux library to return all users within a group so that the correct SELinux user record is used. As a result, users with the correct context can now log in as expected in this scenario.
All users of libselinux are advised to upgrade to these updated packages, which fix these bugs.

4.135. libsemanage

Updated libsemanage packages that fix file creation when umask is changed.
The libsemanage library provides an API for the manipulation of SELinux binary policies. It is used by checkpolicy (the policy compiler) and similar tools, as well as by programs such as load_policy, which must perform specific transformations on binary policies (for example, customizing policy boolean settings).

Bug Fix

BZ#747345
When running semanage commands while umask is set to 027 (or to a similar value that restricts a non-priviledged user from reading files created with such a file-creating mask), semanage changed the permissions of certain files such as the /etc/selinux/mls/contexts/files/file_contexts file. As a consequence, non-priviledged processes were not able to read such files and certain commands such as the restorecon command failed to run on these files. To solve this problem, libsemanage has been modified to save and clear umask before libsemanage creates context files and then restore it after the files are created so the file permissions are readable by non-priviledged processes. Operations on these context files now work as expected.
All users of libsemange are advised to upgrade to these updated packages, which fix this bug.

4.136. libsepol

Enhanced libsepol packages are now available for Red Hat Enterprise Linux 6.
The libsepol library provides an API for the manipulation of SELinux binary policies. It is used by checkpolicy (the policy compiler) and similar tools, as well as by programs like load_policy that need to perform specific transformations on binary policies (for example, customizing policy boolean settings).

Enhancement

BZ#727285
Previously, the libsepol packages were compiled without the RELRO (read-only relocations) flag. As a consequence, programs provided by this package and also programs built against the libsepol libraries were vulnerable to various attacks based on overwriting the ELF section of a program. To increase the security of libsepol programs and libraries, the libsepol spec file has been modified to use the "-Wl,-z,relro" flags when compiling the packages. As a result, the libsepol packages are now provided with partial RELRO protection.
Users of libsepol are advised to upgrade to these updated packages, which add this enhancement.

4.137. libsndfile

Updated libsndfile packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

The libsndfile package provides a library for reading and writing sound files.

Bug Fix

BZ#664323
Prior to this update, the libsndfile package was built without the Ogg container format support. As a result, applications using the libsndfile library were not able to work with the Ogg format. With this update, the problem has been fixed so that applications can now work with the Ogg format as expected.
All users of libsndfile are advised to upgrade to this updated package, which fixes this bug.

4.138. libsoup

Updated libsoup packages that fix one security issue are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
libsoup is an HTTP client/library implementation for GNOME.
Security Fix
CVE-2011-2524
A directory traversal flaw was found in libsoup's SoupServer. If an application used SoupServer to implement an HTTP service, a remote attacker who is able to connect to that service could use this flaw to access any local files accessible to that application via a specially-crafted request.
All users of libsoup should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running applications using libsoup's SoupServer must be restarted for the update to take effect.

4.139. libssh2

An updated libssh2 package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The libssh2 package provides a library that implements the SSH2 protocol.

Bug Fix

BZ#743511
Prior to this update, libssh2 package leaked memory and terminated unexpectedly in certain situations. This update modifies libssh2 so that no more memory leaks occur and now libssh2 works as expected.
Note, that all running applications using libssh2 have to be restarted for the update to take an effect.
All users of libssh2 are advised to upgrade to this updated package, which fixes this bug.

4.140. libtirpc

An updated libtirpc package that fixes one bug is now available for Red Hat Enterprise Linux 6.
The libtirpc package contains SunLib's implementation of transport independent RPC (TI-RPC) documentation. This includes a library required by programs in the nfs-utils and rpcbind packages.

Bug Fix

BZ#714015
Due to certain errors and missing code in libtirpc, user space NFS servers were not able to fully utilize the RPCSEC_GSS security protocol, which allows remote procedure call (RPC) protocols to access the Generic Security Services Application Programming Interface (GSS-API). With this update, the problems have been fixed in the libtirpc code. The RPCSEC_GSS protocol now can be used by NFS servers properly.
All users of libtirpc are advised to upgrade to this updated package, which fixes this bug.

4.141. libvirt

Updated libvirt packages that fix one security issue and several bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remotely managing virtualized systems.
Security Fix
CVE-2011-2511
An integer overflow flaw was found in libvirtd's RPC call handling. An attacker able to establish read-only connections to libvirtd could trigger this flaw by calling virDomainGetVcpus() with specially-crafted parameters, causing libvirtd to crash.

Bug Fixes

BZ#715400
Previously, when the "virsh vol-create-from" command was run on an LVM (Logical Volume Manager) storage pool, performance of the command was very low and the operation consumed an excessive amount of time. This bug has been fixed in the virStorageVolCreateXMLFrom() function, and the performance problem of the command no longer occurs.
BZ#726617
Due to a regression, libvirt used undocumented command line options, instead of the recommended ones. Consequently, the qemu-img utility used an invalid argument while creating an encrypted volume, and the process eventually failed. With this update, the bug in the backing format of the storage back end has been fixed, and encrypted volumes can now be created as expected.
BZ#728516
Due to a bug in the qemuAuditDisk() function, hot unplug failures were never audited, and a hot unplug success was audited as a failure. This bug has been fixed, and auditing of disk hot unplug operations now works as expected.
BZ#728546
Previously, when a debug process was being activated, the act of preparing a debug message ended up with dereferencing a UUID (universally unique identifier) prior to the NULL argument check. Consequently, an API running the debug process sometimes terminated with a segmentation fault. With this update, a patch has been provided to address this issue, and the crashes no longer occur in the described scenario.
BZ#715401
The libvirt library uses the "boot=on" option to mark which disk is bootable but it only uses that option if Qemu advertises its support. The qemu-kvm utility in Red Hat Enterprise Linux 6.1 removed support for that option and libvirt could not use it. As a consequence, when an IDE disk was added as the second storage with a virtio disk being set up as the first one by default, the operating system tried to boot from the IDE disk rather than the virtio disk and either failed to boot with the "No bootable disk" error message returned, or the system booted whatever operating system was on the IDE disk. With this update, the boot configuration is translated into bootindex, which provides control over which device is used for booting a guest operating system, thus fixing this bug.
All users of libvirt are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, libvirtd must be restarted ("service libvirtd restart") for this update to take effect.
Updated libvirt packages that fix multiple bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems.
Bug Fixes
BZ#710150
Due to a bug in the qemuAuditDisk() function, hot unplug failures were never audited, and a hot unplug success was audited as a failure. This bug has been fixed, and auditing of disk hot unplug operations now works as expected.
BZ#711151
Previously, a bug in the qemu-img command line arguments prevented the creation of encrypted volumes. This update fixes the bug, and encrypted volumes can now be successfully created.
BZ#711206
Previously, when a debug process was being activated, the act of preparing a debug message ended up with dereferencing a Universally Unique Identifier (UUID) prior to the NULL argument check. As a consequence, an API running the debug process sometimes terminated unexpectedly with a segmentation fault. With this update, a patch has been applied to address this issue, and crashes no longer occur in the described scenario.
BZ#742646
Due to a programming mistake in the initialization code of the libvirtd daemon, the QEMU driver could have failed to find the user or group ID of the qemu application on the system. As a consequence, libvirtd failed to start. With this update, the error has been corrected and libvirtd now starts as expected.
BZ#741217
If the QEMU driver failed to update information about currently allocated memory, installing a new virtual machine failed with the following error message:
ERROR    cannot send monitor command '{"execute":"query-balloon"}':
Connection reset by peer
With this update, the driver has been modified to not consider this behavior as fatal. Installation now proceeds and finishes as expected.
BZ#690695
Previously, when running the "virsh vol-create-from" command on a Logical Volume Manager (LVM) storage pool, performance of the command was very low and the operation consumed an excessive amount of time. This bug has been fixed in the virStorageVolCreateXMLFrom() function, and the performance problem of the command no longer occurs.
BZ#690175
When migrating a QEMU domain and restarting the libvirtd daemon, the migration was not properly canceled. The domain was left on the target host or ended up in an unexpected state on the source host. With this update, the libvirtd daemon tracks ongoing migrations in a persistent file, and properly cancels them when the daemon is being restarted.
BZ#738146
The "virsh dump" command can fail to dump the core of a domain if the user sets incorrect permissions for the destination directory. Previously, the virsh(1) man page did not provide any information about the permissions required to successfully complete a domain core dump. This information is now included in the man page.
BZ#734773
When shutting down a guest operating system, libvirt killed the QEMU process without giving it enough time to flush all disk I/O buffers. This led in certain cases to loss of data or corruption of the virtual disk. With this update, libvirt gives QEMU enough time to flush the buffers and exits instead of forcibly killing the process.
BZ#738148
When the user started a virtual machine, changed its definition, and migrated the virtual machine, the new settings were not available on the destination. With this update, the settings are transferred to the destination by a live XML file which includes current settings of the running virtual machine. Now, settings are kept during the migration.
BZ#669549
Previously, libvirt did not exercise enough control over whether a domain change should affect the running domain, the persistent configuration, or both. Various virsh commands were inconsistent, and attempts to change a configuration of a running domain did not persist to the next boot. With this update, several libvirt commands have new flags to distinguish between live and persistent configurations. The corresponding virsh commands can be used with the "--config" and "--live" flags to provide a more consistent interface. Management applications have finer control over whether various configuration changes affect hot plug, next boot, or both.
BZ#674537
Various logic bugs affected the handling of snapshots in libvirt. Among these, restarting the libvirtd daemon would lose track of the current snapshot, and a change in QEMU behavior would trigger a latent bug in libvirt's ability to restore certain snapshots. Snapshots were therefore unreliable and hard to manage. This update provides a number of bug fixes and flags to the existing snapshot management APIs, so that libvirt can provide all the snapshot features, as documented. Management applications can use system checkpoint snapshots for better control when rolling back to known stable states of a virtual machine.
BZ#677229
Previously, libvirt did not support attaching of interfaces to an inactive virtual machine by using the "virsh attach-interface" command. Users had to use workarounds, for example editing the whole domain by executing "virsh edit". This update adds support for attaching interfaces even to inactive virtual machines. As a result, users do not need to use the workarounds, but can use virsh directly.
BZ#727474
Previously, libvirt used an improper separator (comma) in the "lvs" command. This caused the regular expression, which is used to parse the "lvs" output, to not function correctly. In addition, libvirt did not use the right mechanism to format multiple XML "devices" elements for multiple device paths of a striped volume. As a consequence, creation of any logical pool failed for LVM volume groups with striped volumes. With this update, a different separator (hash) is used. Multiple device paths of a striped volume are parsed correctly and multiple XML "devices" elements are formated as expected. Users are now able to create logical pools which contain a striped volume, and get proper XML for the striped volume as well.
BZ#720269
If the source QEMU process was not able to connect to the destination process when migrating a QEMU domain, libvirt could report "undefined error". With this update, libvirt creates the connection to the destination QEMU process and makes QEMU use this pre-created connection. This allows libvirt to report meaningful errors if the connection attempt fails.
BZ#707257
If a NFS (Network File System) storage was configured to be accessible only by users from a supplementary group for a user whose identity was used to run QEMU processes, the libvirtd daemon in certain cases failed to access or create files on that storage. With this update, libvirtd properly initializes supplementary groups when changing identity to QEMU users and groups. This allows libvirtd to access and create such files.
BZ#698825
Previously, it was not possible to maximize the performance of a KVM guest using memory binding on a NUMA (Non-Uniform Memory Access) host if the guest was started by libvirt. This update introduces new XML definitions to support NUMA memory policy configuration. Users can now specify the NUMA memory policy by using the guest XML definitions. The performance can be adjusted by NUMA memory binding.
BZ#704144
The libvirt library uses the "boot=on" option to determine which disk is bootable. The previous version of the qemu-kvm utility did not support this option, and libvirt could not use it. As a consequence, when an IDE disk was added as the second storage with a virtio being set up as the first one by default, the operating system tried to boot from the IDE disk rather than the virtio disk and either failed to boot with the "No bootable disk" error message, or the system booted whatever operating system was on the IDE disk. With this update, the boot configuration is translated into bootindex, which provides control over which device is used for booting a guest operating system.
BZ#751900
Prior to this update, when a QEMU migration to a file was triggered, libvirt temporarily set the migration bandwith to "unlimited" in an attempt to speed up saving of the state of the virtual machine. A limitation in QEMU caused QEMU not to return from the migrate command until the migration itself was complete. This locked out the QEMU monitor response loop and the migration to file process could not be interrupted. With this update, migration to file can be monitored for progress or interruptions. Now, libvirt no longer ignores job info or abort commands during the migration to file process.
BZ#738970
The virsh(1) man page did not mention detailed information about the drivers used for the "attach-disk" command with QEMU domains. If the command on a QEMU domain failed with an incorrect driver, users were unaware of what driver name should be used with QEMU. To fix this problem, the manual page now specifies what the "driver" parameter can contain.
BZ#693203
Running the "virsh list" command could become unresponsive when a QEMU process tracked by the libvirtd daemon did not respond to the monitor command. With this update, "virsh list" no longer requires interaction with running QEMU processes and can therefore list all domains even if a guest becomes unresponsive.
BZ#691830
If the user wanted to take a screenshot of a running virtual machine, the user had to use other tools (for example, virt-manager). A new libvirt API, virDomainScreenshot, is provided with this update, and allows users to take screenshots if the hypervisor supports it. Now, users no longer need to use third-party tools to take screenshots, but can use libvirt directly.
BZ#682237
SPICE (the Simple Protocol for Independent Computing Environments) supports multiple compression settings for audio, images and streaming. With this update, the libvirt XML schema is extended to support these kinds of settings so that users can set SPICE compression options directly in libvirt.
BZ#682084
Previously, libvirt did not support virtual CPU pinning on inactive virtual machines by running the "virsh vcpupin" command. Users had to use workarounds instead. With this update, libvirt now supports virtual CPU pinning on inactive virtual machines. Users no longer need to use workarounds but can use virsh directly.
BZ#681458
Previously, libvirt did not support attaching devices to an inactive virtual machine by running the "virsh attach-device" command. Users had to use workarounds, for example had to edit the whole domain using "virsh edit". With this update, libvirt provides enhanced support for attaching devices even to inactive virtual machines. User no longer need to use their workarounds but can use virsh directly.
BZ#727088
Previously, the new storage type added to libvirt was not fully supported. As a consequence, directory type storage volumes were reported to be file storage volumes. The new volume type has been added to the public API. The volume type is now correctly reported and displayed in associated tools.
BZ#641087
Users were allowed to change the domain's CPU affinity dynamically in libvirt, however there was no persistent XML provided, and the settings were lost on the next domain start. This update introduces a new XML to support the persistent configuration of domain's CPU affinity. Also new flags ("--live, "--config", and "--current") are introduced for the "virsh vcpupin" command. Now, the domain's CPU affinity persists across the next start.
BZ#730750
Previously, libvirt attempted to load a managed save file instead of starting a domain from the beginning, even if the managed save file was damaged and could not be loaded. This could confuse users who were not aware of the problem. This update introduces a new command, "virsh start --force-boot", as well as improved logic which ensures that a managed save file is not loaded if it is corrupted. Use of managed save images no longer cause confusion.
BZ#728153
If both the SysV init and upstart scripts were installed, and the libvirtd daemon was managed by upstart, the SysV init script was unaware of this. As a consequence, the SysV init script reported confusing error messages. The user was unable to restart the daemon by using the SysV init script, and was also unaware of the fact, that libvirtd was managed by upstart. With this update, the SysV init script checks whether libvirtd is managed by upstart. In the positive case, the user is advised to use the upstart tools to manage libvirtd. Users are now able to restart the libvirtd daemon while using upstart.
BZ#728428
When restarting the libvirtd daemon, libvirt reloaded the domain configuration from the status XML if the XML existed (the domain was running). However, the original domain configuration was not recorded and the domain configuration could not be restored to the original one. As a consequence, the nonpersistent attached devices still existed after restarting libvirtd. With this update, the original domain configuration is recorded by assigning the persistent domain configuration to the newDef method if it's NULL and the domain is running. The nonpersistent attached devices no longer exist if libvirtd is restarted.
BZ#728654
The broken configuration file caused the libvirtd daemon to exit silently, with no error messages logged or any other indication of a problem. This could have confused the user as a consequence. Error handling messages have been added to the early start phases of libvirtd. Errors which occur during the start are now printed and logged.
BZ#678027
Previously, the DMI (Desktop Management Interface) data was not present on all architectures. Running the "virsh sysinfo" command failed on certain architectures because the DMI data was obtained from the missing /sys/devices/virtual/dmi tree. With this update, the DMI information is no longer fetched on non-Intel architectures. As a result, running the "virsh sysinfo" command works as expected.
BZ#730244
Previously, an invalid variable was used to construct error messages. If a migration command failed, the error message reported the remote URI to be "(null)" instead of the requested migration URI. The reason why the command failed was therefore unknown to the user. This update implements the correct variable which contains the migration URI. As a result, the correct migration URI is now reported if an error occurs.
BZ#667631
The monitor command in QEMU that provides migration information for SPICE was modified. As a consequence, libvirt was unable to send the migration information to SPICE, the session failed, and the migration terminated. This update modifies libvirt to adapt to the new monitor command. As a result, users can now perform a successful migration.
BZ#667624
The monitor command in QEMU that is used to change passwords for VNC and SPICE sessions was changed. As a consequence, libvirt was unable to set any password. This update modifies libvirt to adapt to the new command. As a result, users can successfully set passwords for VNC and SPICE sessions.
BZ#667620
Because QEMU changed the format of SPICE events, libvirt was not able to resend these event to users. This update modifies libvirt to adapt to the the new format. As a result, SPICE events are successfully passed to users through libvirt.
BZ#589922
In certain cases, usually when the virt_use_nfs_selinux boolean was not set, SELinux policies prevented qemu from opening a disk image. As a consequence, qemu refused to start. This update provides a verbose error message which advises the user to set virt_use_nfs_selinux in the aforementioned scenario.
BZ#697742
Previously, libvirt did not remove the managed save file if a domain was undefined. When the user installed a new guest after destroying and undefining the previous one, the managed save file for the previous guest was still present, and the new guest failed to start because it would use a managed save file with the same name. This update introduces a new API, virDomainUndefineFlags, which allows users to specify flags (for example, "virsh undefine --managed-save"). The managed save file can now be successfully removed. If the user does not specify any option, a comprehensive error message provides additional information.
BZ#722862
Previously, the virsh(1) man page contained duplicate documentation of the "iface-name" command, did not provide sufficient documentation of the "iface-mac" command, and contained certain inconsistent option names. The man page has been modified to provide correct descriptions.
Enhancements
BZ#705814
The libvirt packages have been upgraded to upstream version 0.9.4, which introduces new APIs for libvirt and adds various enhancements over the previous version.
BZ#632760
In certain scenarios, users want to adjust the traffic of a virtual machine, its specific NIC (Network Interface Controller), or whole virtual network. Prior to this update, users often manually ran scripts to set up traffic shaping. This update extends the network and interface XML definitions. Now, users can set bandwidth limitation, or specify average peak and burst rates directly in libvirt.
BZ#692769
Users can limit virtual CPUs of a virtual machine by using control groups (cgroups). However, the appropriate QEMU process needs to be placed into a specific cgroup. Prior to this update, libvirt was missing this feature, and users had to use their own workarounds. With this update, libvirt can place a process into a cgroup, which can also be specified by using the XML definition of a virtual machine. As a result, users can now set virtual CPU bandwidth limits directly in libvirt.
BZ#711598
With SGA BIOS, it is possible to send boot messages to a serial line instead of a VNC/SPICE session. With this update, libvirt contains enhanced virtual machine XML descriptions so that users can set a serial line that allows the showing of boot messages. Boot messages are now displayed on the serial console as expected.
BZ#643947
The physical network interface configuration can be different on each host machine, even though each host is using the same logical network. This update adds a virtual switch abstraction to libvirt. Virtual machines can be configured identically on every host, even if the physical connectivity is different.
BZ#698340
Previously, libvirt did not support setting of the ioeventfd feature for virtio disks or interfaces. QEMU could experience high CPU usage as a consequence. The support for this feature has been added in the XML definition of a virtual machine. Users can now enable the ioeventfd feature in order to lower CPU usage.
BZ#703851
The address used for listening for VNC connections to a libvirt guest was previously required to be an IP address. In cases where the guest migrates from one host to another, and the administrator wants the guest to be listening on a publicly visible interface, this address must be changed during migration. To make this change possible this update adds the option for specifying a listen network by name. Now, the guest can be migrated between the hosts, and its VNC listen address changes automatically as it migrates.
BZ#598792
The "--persistent" option for the "update-device" command was not implemented in virsh. Users experienced error messages saying that this feature was not supported. This update modifies libvirt to distinguish between the live and persistent XML definition of a virtual machine. Users can now change the definition of a virtual machine while the machine is running. The settings are applied after restarting the virtual machine.
BZ#632498
Running the "virsh dump" command against a virtual machine caused it to dump its memory. However, users often had to manually reboot the virtual machine after performing a dump. A new option, "--reset", has been implemented for "virsh dump", so that users can now use virsh instead of other tools.
BZ#677228
Previously, libvirt did not support attaching disks to an inactive virtual machine by using the "virsh attach-disk" command. Users had to use workarounds instead. This update provides enhanced support for attaching disks; disks can be attached even to inactive virtual machines. Now, users can use virsh directly instead of using workarounds.
BZ#569567
Changes made to host's network configuration by libvirt immediately and permanently modified host's configuration files. This caused the network to be unusable, and it was sometimes difficult to restore the original connectivity. This update adds new virsh commands, so that the current state of the network configuration can be saved and easily reverted.
BZ#634653
When migrating to a file, saving the state of a virtual machine led to creation of large files which filled the system cache. The system performance could therefore be affected. This update introduces the new "--bypass" option for operations that involve migration to file. This prevents the cache from being filled. Management application can now control large virtual machine state files.
All users of libvirt are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
Updated libvirt packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. The library also provides nwfilter support for fine-grained filtering of the network traffic reaching guests managed by libvirt.

Bug Fix

BZ#754182
Previously, nwfilter support was dependent on the ability to execute scripts in the /tmp directory, which is considered unsafe. With this ability blocked, guests relying on the nwfilter component were not allowed to start. The underlying code has been modified so that nwfilter no longer requires to execute scripts in the /tmp directory.
All users of libvirt are advised to upgrade to these updated packages, which fix this bug. After installing these updated packages, libvirtd must be restarted. Use the "service libvirtd restart" command for this update to take effect.
Updated libvirt packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. The library provides the libvirtd daemon, which is required for virtualization management of KVM and LXC.

Bug Fixes

BZ#743557
Due to a programming error in the initialization code of the libvirtd daemon, the QEMU driver could have failed to find the user or group ID of the qemu application on the system. As a result, libvirtd failed to start. With this update, the error has been corrected and libvirtd now works as expected.
BZ#747358
If the QEMU driver failed to update information about currently allocated memory, installing a new virtual machine could have failed with the following error message:
ERROR cannot send monitor command '{"execute":"query-balloon"}': Connection reset by peer
With this update, the driver has been modified to not consider this behavior as fatal. Installation now proceeds and finishes as expected.
All users of libvirt are advised to upgrade to these updated packages, which fix this bug. After installing these updated packages, libvirtd must be restarted. Use the "service libvirtd restart" command for this update to take effect.

4.142. libvirt-cim

An updated libvirt-cim package that fixes one bug and adds two enhancements is now available for Red Hat Enterprise Linux 6.
The libvirt-cim package contains a Common Information Model (CIM) provider based on Common Manageability Programming Interface (CMPI). It supports most libvirt virtualization features and allows management of multiple libvirt-based platforms.

Bug Fix

BZ#728245
Prior to this update, libvirt-cim contained several defects for null variables. As a result, using null variables did not work as expected. This update resolves these defects and now null variables work as expected.

Enhancements

BZ#633337
With this update, libvirt-cim supports libvirt networking Access Control Lists (ACL).
BZ#712257
This update aprovides read-only access to ensure that the remote CIM access cannot modify the system state. This is useful when CIM is used only for monitoring and other software is used for virtualization management.
All libvirt-cim users are advised to upgrade to this updated package, which fixes this bug and adds these enhancements.

4.143. libXfont

Updated libXfont packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having important security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link associated with the description below.
The libXfont packages provide the X.Org libXfont runtime library. X.Org is an open source implementation of the X Window System.
Security Fix
CVE-2011-2895
A buffer overflow flaw was found in the way the libXfont library, used by the X.Org server, handled malformed font files compressed using UNIX compress. A malicious, local user could exploit this issue to potentially execute arbitrary code with the privileges of the X.Org server.
Users of libXfont should upgrade to these updated packages, which contain a backported patch to resolve this issue. All running X.Org server instances must be restarted for the update to take effect.

4.144. libxml2

Updated libxml2 packages that fix several security issues and various bugs are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links associated with each description below.
The libxml2 library is a development toolbox providing the implementation of various XML standards. One of those standards is the XML Path Language (XPath), which is a language for addressing parts of an XML document.
Security Fixes
CVE-2011-0216
An off-by-one error, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XML files. A remote attacker could provide a specially-crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
CVE-2011-1944
An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way libxml2 parsed certain XPath expressions. If an attacker were able to supply a specially-crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash or, possibly, execute arbitrary code.
CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, CVE-2011-2834
Multiple flaws were found in the way libxml2 parsed certain XPath expressions. If an attacker were able to supply a specially-crafted XML file to an application using libxml2, as well as an XPath expression for that application to run against the crafted file, it could cause the application to crash.

Note

Red Hat does not ship any applications that use libxml2 in a way that would allow the CVE-2011-1944, CVE-2010-4008, CVE-2010-4494, CVE-2011-2821, and CVE-2011-2834 flaws to be exploited; however, third-party applications may allow XPath expressions to be passed which could trigger these flaws.
Red Hat would like to thank the Google Security Team for reporting the CVE-2010-4008 issue. Upstream acknowledges Bui Quang Minh from Bkis as the original reporter of CVE-2010-4008.

Bug Fixes

BZ#732335
A number of patches have been applied to harden the XPath processing code in libxml2, such as fixing memory leaks, rounding errors, XPath numbers evaluations, and a potential error in encoding conversion.
All users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The desktop must be restarted (log out, then log back in) for this update to take effect.

4.145. lldpad

An updated lldpad package that fixes several bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The lldpad package provides the Linux user space daemon and configuration tool for Intel's Link Layer Discovery Protocol (LLDP) agent with Enhanced Ethernet support.
The lldpad package has been upgraded to upstream version 0.9.43, which provides a number of bug fixes and enhancements over the previous version. (BZ#731407)

Bug Fixes

BZ#749057
The Brocade 8000 Fibre Channel Forwarder (FCF) switch with FabOs 6.4.2b failed to process the CEE TLV frame on fabric session startup (started by the llpad). As a consequence, the Brocade 8000 Fibre Channel Forwarder (FCF) switch with FabOs 6.4.2b terminated the connection and subsequent fabric logins failed when IEEE 802.1Qaz DCBX was enabled. With this update, the llptool utility can configure lldpad not to use the CEE TLV frame for the fabric session initiation (for the eth3 device, the initiator should issue the "lldptool -T -i eth3 -V IEEE-DCBX mode=reset" command) and the problem no longer occurs.
BZ#694639
The lldpad service triggered excessive timeout events every second. This caused the service to consume excess resources. Now, the lldpad service has been switched from polling-based to a demand-based model. This prevents excessive timeout event generation and ensures that the service consumes only the expected resources.
BZ#733123
The lldpad utility did not detect the maximum number of traffic classes supported by a device correctly. This resulted in an invalid or incorrect hardware configuration. Now, the utility detects the maximum number of traffic classes correctly.
BZ#720825, BZ#744133
The Edge Control Protocol (ECP) could not verify whether a port lookup was successful when running Virtual Discovery and Configuration Protocol (VDP) on bonded devices because VDP does not support bonded devices. As a consequence, the LLDP agent terminated unexpectedly with a segmentation fault. With this update, VDP is no longer initialized on bonded devices and the crash no longer occurs.
BZ#647211
The lldpad utility failed to initialize correctly on the Intel 82599ES 10 Gigabit Ethernet Controller (Niantic) with virtual functions enabled and returned a message that there were too many neighbors. With this update, lldpad initializes correctly and the problem no longer occurs.
BZ#735313
Prior to this update, a user with non-superuser permissions could start the lldpad service. With this update the lldpad init scripts have been modified and a user with non-superuser permissions can no longer start the service.
BZ#683837
The init script did not perform a line feed when returning the output of a service command. With this update, the init script has been recoded and the output of the service command is correct.
BZ#720730
The get_bcn() function returned without freeing the nlh variable, which caused a memory leak. The function has been modified and the memory leak no longer occurs.
BZ#741359
The lldpad daemon failed to detect that a NIC (Network Interface Card) had the offloaded DCBX (Data Center Bridging eXchange) stack implemented in its firmware. As a consequence, the lldp packets were send by both, the daemon and the NIC. With this update, the lldpad daemon no longer sends the packets if a NIC driver implements the offloaded DCBX stack.
BZ#749943
The lldpad utility incorrectly accessed memory. With this update, the utility accesses the memory correctly.

Enhancement

BZ#695550
The lldpad package now supports the 802.1Qaz standard (Enhanced Transmission Selection for Bandwidth Sharing Between Traffic Classes).
Users are advised to upgrade to this updated lldpad package, which fixes these bugs and adds these enhancements.
An updated lldpad package that fixes one bug is now available for Red Hat Enterprise Linux 6.

4.156. luci

An updated luci package that fixes multiple bugs and adds various enhancements is now available for Red Hat Enterprise Linux 6.
The luci package contains a web-based high availability cluster configuration application.
Bug Fixes
BZ#599074
When defining a cluster and checking the Use the Same Password for All Nodes box, an error message, saying that the user did not enter a password for any of the clusters except the first one, appeared after the user had submitted the changes. The password synchronization was triggered only once by checking the box. As a consequence, if no password was entered before checking the box, none could be copied into the other password fields. This update fixes the problem so that filling any single password field in the form causes the password to be correctly submitted for every node affected.
BZ#632536
Upgrading or downgrading the luci package could result in SELinux AVC (Security-Enhanced Linux Access Vector Cache) denials due to the python applications searching for local customizations in the Home directory. With this update, Python's paste tool now uses the -Es flag, and so avoids this behavior.
BZ#639121
If changes were made in any of the lightbox dialog boxes, a dialog box was hidden instead of being reset after it had been closed. As a consequence, when the dialog box was reopened, it was in the same state as before closing. The only way to reset the state of the dialog box was to refresh the page in the browser. Now, when the user closes the existing dialog box, the page refreshes automatically instead of trying to recreate the initial state.
BZ#643488
Previously, titles of certain dialog boxes in the luci UI contained inconsistent character casing. Now, character casing is consistent in all titles.
BZ#703574
Previously, luci did not provide any way to back up or restore the content of the database. With this update, the content of the luci database located in /var/lib/luci/data/luci.db can be fully backed up and restored.
BZ#705111
In luci, when editing a failover domain that had both the Restricted and Prioritized boxes unchecked, adding of a node had no effect. The operation appeared to be successful, however the node was not added to the domain in the cluster.conf file. With this update, nodes can be successfully added to the failover domain. Removing nodes from the failover domain now works correctly as well.
BZ#705884
Previously, a bug in luci resulted in luci not being able to parse lines which contained the name of a service ending with the ".1" suffix. As a consequence, when importing a cluster, luci logged an error or displayed the Error 500 message in the browser. This update removes the bug and luci can now parse names ending with ".1" correctly.
BZ#707918
When the user created a file system resource and then tried to edit any field of a cluster service, an error message was printed and the changes were not applied. With this update, the source code is modified so that the changes are successfully applied.
BZ#708205
Previously, the Run Exclusive checkbox on the administration panel for a service group did not correspond to the configuration of this service group's entry in the cluster.conf file. The Run Exclusive option was enabled in luci by default, without it being manually enabled, and services could therefore become exclusive without users knowing about it. Now, luci is modified to correspond with the cluster.conf file: if the Run Exclusive option is not enabled, the checkbox is not checked.
BZ#711625
Due to luci not showing the migrate action for virtual machines, the Error 500 error message could appear when attempting to create a cluster of KVM (Kernel-based Virtual Machine) guests. With this update, luci is modified so that the services can be started and edited successfully.
BZ#714285
Prior to this update, the stop/start service was performed instead of migration when migrating a virtual machine by choosing the Migrate to node... option in the drop down menu on the Service Details page. With this update, the source code is modified to successfully complete the migration of virtual machines using the web interface.
BZ#718355
Prior to this update, if Log debugging messages and Log messages to log file were enabled in the Logging page and the user entered a file path in the textbox below, the Error 500 message appeared. The changes to logging could not be submitted as a consequence. This problem has been fixed and changes to logging are submitted correctly.
BZ#729730
Prior to this update, luci served web pages and XHTML documents for most of the web browsers with the "application/xhtml+xml" content type and with "application/xml and "text/html" as failback. Web pages for the Internet Explorer browser were consistently served with the "text/html" content type. As a consequence, users were unable to open the URL of the luci server using Internet Explorer 8.0 and an error message appeared instead. With this update, web pages are permanently served with the "text/html" content type. The login page shows up correctly and users are able to log in.
BZ#733084
When trying to save an empty value for an option that used to be non-empty before instead of removing such option from the cluster.conf file, it was saved as the previous non-empty value. If the user attempted to clear options for a virtual machine service that he had been configured, luci did not save configuration for the service and it was therefore impossible to clear them using only the web interface. This problem has been fixed and the options are now cleared properly.
BZ#733797
Previously, luci did not start a service on a preferred node. When the user chose a service with a failover domain on the Service Groups page, a service started on the first node even if the user did not choose the first node as the preferred one. Now, the Submit button is used instead of a link for the headers_detail form and thus fixes the problem.
Enhancements
BZ#522005
The previous version of luci did not provide any role-based access control system. With this update, luci contains a new system for managing user roles. Multiple users can now gain various privileges for managing or accessing clusters.
BZ#671285
Now, a warning message is displayed when the user logs in for the first time in the luci UI. The text warns users about possible problems related to managing clusters using the UI with no further knowledge of clustering.
BZ#664036
This update provides a confirmation dialog box, which appears when removing cluster nodes or the whole cluster by selecting all the nodes and clicking the Delete button.
BZ#705072
This update adds support for the new fence_vmware fence agent.
Users of luci are advised to upgrade to this updated package, which fixes these bugs and adds these enhancements.

4.157. lvm2

Updated lvm2 packages that fix several bugs and add three enhancements are now available for Red Hat Enterprise Linux 6.
The lvm2 packages contain support for Logical Volume Management (LVM).
Bug Fixes
BZ#743112
Due to locking errors, multiple failed cmirror devices were unable to be replaced. With this update, the underlying source code has been modified to address this issue, and the aforementioned devices are correctly replaced should a failure occur.
BZ#696251
Prior to this update, extending a mirror volume beyond available extents while using the cling by tags allocation policy did not work properly. Normally, such an action returns an error message informing the user that there are insufficient allocatable extents for use. However, this check failed and caused a volume to be corrupted. Because the allocation code has been revised, restructured, and made more robust, the problematic scenario with extending mirror volumes while using the cling by tags policy no longer occurs.
BZ#684083
While performing extensive I/O operations in the background, the pvmove command could become unresponsive. With this update, the underlying source code has been modified to address this issue, and the pvmove command no longer hangs.
BZ#733320
When a striped logical volume was resized with the lvresize command, the size was rounded down to the stripe boundary. This could pose a problem when shrinking the volume with a file system on it. Even if a user determined the new size so that the file system did fit entirely onto the volume, and resized the volume, the alignment done by the lvresize command might have cut off a part of the file system, causing it to become corrupted. This update fixes the rounding for striped volumes so that a volume is never reduced more than requested.
BZ#594525
Prior to this update, placing mirror legs on different physical devices with the lvcreate --alloc anywhere command did not guarantee placement of data on different physical devices. With this update, the above command tries to allocate each mirror image on a separate device first before placing it on a device that is already used.
BZ#737087
If the lvcreate command was used with large physical volumes while using %FREE, %VG, %PVS or %ORIGIN for size definition, the resulting LV size was incorrectly calculated. This was caused by an integer overflow while calculating the percentages. This update provides a better way of calculating the sizes, by using proper typecasting, so that the overflow no longer occurs.
BZ#715190
Several LVM locking error and warning messages were returned during the system start-up which were caused by cluster locking (configured globally in /etc/lvm/lvm.conf). At the early stage of the system start-up, when the early init script tries to activate any existing VGs, the cluster infrastructure is still not initialized (as well as the network interface) and therefore cluster locking cannot be used and the system falls back to file-based locking instead, causing several misleading error and warning messages to be returned. With this update, these error and warning messages are suppressed during the system start-up, and the system falls back to usable locking mechanism silently.
BZ#712147
The vgimportclone script triggered a code path in LVM that caused it to access already-released memory when a duplicated PV was found. Consequently, the VG that contained such PV was found to be inconsistent and the process ended up with a failure to read the VG. This update fixes this failure by saving such problematic strings to a temporary buffer, and thus avoiding improper memory access.
BZ#697945
The cluster LVM daemon (clvmd) was crashing when attempting to create a high number of volume groups at once. This was caused by the limit set by the number of available file descriptors per process. While clvmd was creating pipes and the limit was reached under the pressure of high number of requests, clvmd did not return an error but continued to use uninitialized pipes instead, eventually causing it to crash. With this update, clvmd now returns an error message immediately if the pipe creation fails.
BZ#734193
When using striped mirrors, improper and overly-restrictive divisibility requirements for the extent count could cause a failure to create a striped mirror, even though it was correct and possible. The condition that was checked counted in the mirror count and the stripe count, though, only the stripe count alone was satisfactory. This update fixes this, and creating a striped mirror no longer fails.
BZ#732142
Before, an improper activation sequence was used while performing an image split operation. That caused a device-mapper table to be loaded while some of processed devices were known to be suspended. This has been fixed and the activation sequence has been reordered so that the table is always loaded at proper time.
BZ#570359
Issuing an lvremove command could cause a failure to remove a logical volume. This failure was caused by processing an asynchronous udev event that kept the volume opened while the lvremove command tried to remove it. These asynchronous events are triggered when the watch udev rule is applied (it is set for device-mapper/LVM2 devices when using the udisks package that installs /lib/udev/rules.d/80-udisks.rules).
To fix this issue, the number of device open calls in read-write mode has been minimized and read-only mode is used internally if possible (the event is generated when closing a device that has the watch rule set and is closed after a read-write open).
Although this fixes a problem when opening a device internally within the command execution, the failure could still occur when using several commands quickly in a sequence where each one opens a device for read-write and then closes it immediately (for example in a script). In such a case, it is advisable to use the udevadm settle command in between.
BZ#695526
With this update, when using the lvconvert command, the Unable to create a snapshot of a locked|pvmove|mirrored LV error message has been changed to Unable to convert an LV into a snapshot of a locked|pvmove|mirrored LV. for clarity reasons.
BZ#711445
A hostname containing the slash character (/) caused LVM commands to fail while generating an archive of current metadata. Because a hostname is a part of the temporary archive file name, a file path that was ambiguous was created, which caused the whole archive operation to fail. This update fixes this by replacing any slash character (/) with a question mark character (?) in the hostname string and then is used to compose the temporary archive file name.
BZ#712829
An issue was discovered when running several commands in parallel that activated or deactivated an LV or a VG. The symbolic links for LVs in /dev were created and removed incorrectly, causing them to exist when the device had already been removed or vice versa.
This problem was caused by the fact that during the activation there was no write lock held that would protect individual activation commands as a whole (there was no metadata change). Together with non-atomicity of checking udev operations, an improper decision was made in the code based on the already stale information. This triggered a part of the code that attempted to repair the symbolic links as a fallback action.
To fix this, these checks are no longer run by default, thus fully relying on udev. However, the old functionality can still be used for diagnosing other udev related problems by setting a new verify_udev_operations option found in the activation section of the /etc/lvm/lvm.conf file.
BZ#728157
This update removes the unsupported --force option from the lvrename manpage.
BZ#743932
With this update, the vgsplit command is now able to split a volume group containing a mirror with mirrored logs.
Enhancements
BZ#623808
Prior to this update, it was not possible to create a PV object with all properties calculated (for example, the PE start value) without a need to write the PV label on the disk while using an LVM2 library (lvm2app). This has been changed so that the PV label is written out later in the process as a part of the lvm_vg_write call, making it possible to calculate all PV properties and query them without actually writing the PV label on the disk.
BZ#651493
This update adds support for issuing discards (TRIM) as part of lvm2 operations.
BZ#729712
In Red Hat Enterprise Linux 6.2, support for MD's RAID personalities has been added to LVM as a Technology Preview. For more information about this feature, refer to the Red Hat Enterprise Linux 6.2 Release Notes.
Users are advised to upgrade to these updated lvm2 packages, which resolve these issues and add these enhancements.
An updated lvm2 package that fixes a bug is now available for Red Hat Enterprise Linux 5.
The lvm2 package provides support for Logical Volume Management (LVM).

Bug Fix

BZ#732006
When running the "lvconvert" command to convert a linear device to a mirror with stripes, the "lvconvert" command entered an infinite loop.The problem occurred if the number of needed extents was not divisible by the number of areas. This has been fixed: the allocation is now properly rejected if the number of extents is not divisible by the number of areas.
All users of lvm2 are advised to upgrade to this updated package, which fixes this bug.

Metamail reads the mailcap file to determine how it should display non-text or multimedia material. mailcap associates a particular type of file with a particular program that a mail agent or other program can call in order to handle the file. Mailcap should be installed to allow certain programs to be able to handle non-text files.

Bug Fix

BZ#610793
Prior to this update, the mime.types database did not contain the WebM MIME type (video/webm). The problem has been resolved in this update by including the MIME type in the database.
All users of mailcap are advised to upgrade to this updated package, which fixes this bug.

4.161. mailman

An updated mailman package that fixes various bugs is now available for Red Hat Enterprise Linux 6.
Mailman is a program used to help manage email discussion lists.

Bug Fixes

BZ#704699, BZ#703389
Previously, a number of Python scripts and subdirectories in the /usr/lib/mailman/ directory were group writable. As a result, the respective files and subdirectories could have been changed not only by the owner, but also by other users in the same user group. This undesired behavior has been resolved in this update so that only the owner can now change the files and subdirectories.
BZ#684622
Because of a bug in the brp-python-compile script file, unnecessary /etc/mailman/mm_cfg.pyc and /etc/mailman/mm_cfg.pyo files were generated under certain circumstances. As a result, the Mailman build process could have failed. This update fixes the aforementioned bug by compiling Python script files manually so that the build process no longer fails.
BZ#636825
In accordance with current guidelines, all Python executable files have been updated to use the Python executable file directly, that is the "#!/usr/bin/python" string instead of "#!/usr/bin/env python".
All users of mailman are advised to upgrade to this updated package, which fixes these bugs.
