RHBA-2013:1397 - kernel bug fix update

Synopsis

kernel bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated kernel packages that fix two bugs are now available for Red Hat Enterprise Linux 6 Extended Update Support.

Description

The kernel packages contain the Linux kernel, which is the core of any Linux operating system.

This update fixes the following bugs:

• Previously, the be2net driver failed to detect the last port of BE3 (BladeEngine 3) when UMC (Universal Multi-Channel) was enabled. Consequently, two of the ports could not be used by users and error messages were returned. A patch has been provided to fix this bug and be2net driver now detects all ports without returning any error messages. (BZ#1004659)

• When a copy-on-write fault happened on a Transparent Huge Page (THP), the 2 MB THP caused the cgroup to exceed the "memory.limit_in_bytes" value but the individual 4 KB page was not exceeded. Consequently, the Out of Memory (OOM) killer killed processes outside of a memory cgroup when one or more processes inside that memory cgroup exceeded the "memory.limit_in_bytes" value. With this update, the 2 MB THP is correctly split into 4 KB pages when the "memory.limit_in_bytes" value is exceeded. The OOM kill is delivered within the memory cgroup; tasks outside the memory cgroups are no longer killed by the OOM killer. (BZ#1005060)

Users should upgrade to these updated packages, which contain backported patches to correct these bugs. The system must be rebooted for this update to take effect.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.
