RHBA-2013:1712 - Bug Fix Advisory

Topic

Updated numactl packages that fix two bugs are now available for Red Hat
Enterprise Linux 6.

Description

The numactl packages provide a simple Non-Uniform Memory Access (NUMA) policy
support and consist of the numactl program to run other programs with a specific
NUMA policy and the libnuma library to do allocations in applications using the
NUMA policy.

This update fixes the following bugs:

• Prior to this update, the "localalloc" option was not described clearly in the

numactl(8) manual page, which could cause confusion. This update adds a clear
description of "localalloc" to the numactl(8) manual page. (BZ#881779)

• Due to a bug in the numastat utility source code, output of the "numastat -m"

command reported incorrect values of the amount of allocated static huge page
memory. A patch has been applied to address this bug, and numastat now
calculates huge page sizes properly. (BZ#987507)

Users of numactl are advised to upgrade to these updated packages, which fix
these bugs.

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
