RHBA-2009:0139 - Bug Fix Advisory

Topic

An updated numactl package that fixes various bugs is now available.

Description

numactl is Simple NUMA policy support. It consists of a numactl program to
run other programs with a specific NUMA policy, as well as a libnuma
library with which to do allocations with NUMA policy in applications.

These updated numactl packages provide fixes for the following bugs:

• the command "numactl --physcpubind" gave incorrect results for systems

with more than 63 CPUs due to an off-by-one error.

• the description for the numa_node_to_cpus() function in the numa(3)

manual page has been updated and clarified.

• the declaration for the get_mempolicy() function has been changed to

avoid the risk of invalid compile-time checks.

All users of numactl are advised to upgrade to these updated packages,
which resolve these issues.

Solution

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