RHBA-2016:0186 - numactl bug fix update

Synopsis

numactl bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated numactl packages that fix one bug are now available for Red Hat Enterprise Linux 7.

Description

The numactl packages provide a simple Non-Uniform Memory Access (NUMA) policy support. They 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 bug:

• Previously, when the numa_node_to_cpus() function was called on a node which did not have an entry in the sysfs directory, the libnuma library always printed a warning message about an invalid sysfs. Consequently, libnuma printed the confusing warning message also for physically non-existing nodes (for example, for non-contiguous node numbers) and this warning could not be overridden when the function was called using the dlsym interface. With this update, the mentioned warning message is printed just for NUMA nodes that were found during an initial scan but then did not appear in sysfs. As a result, users of libnuma no longer receive the warning message for non-contiguous node numbers. (BZ#1296266)

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