RHBA-2008:0127 - Bug Fix Advisory

Topic

Updated kernel packages that fix several bugs and add an enhancement are
now available for Red Hat Enterprise Linux 4.5 Extended Update Support.

Description

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

These updated packages fix the following bugs:

• the kernel could run out of memory when creating audit log messages for

certain system calls.

• in certain situations, running the "pvmove" command caused a kernel

panic. These updated packages contain a backported patch, which resolves
this issue.

As well, these updated packages add the following enhancement:

• some of the functionality of the kernel Application Binary Interface

(kABI) tracking module has been implemented. This backported module is used
with para-virtualized drivers.

Red Hat Enterprise Linux 4 users are advised to upgrade to these updated
packages, which resolve these issues and add this enhancement.
