RHBA-2014:1404 - tuna bug fix update

Synopsis

tuna bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated tuna packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

Description

The tuna packages provide an interface for changing both scheduler and IRQ tunables, at whole CPU, per-thread or per-IRQ levels. tuna allows CPUs to be isolated for use by a specific application and threads and interrupts to be moved to a CPU simply by dragging and dropping them.

The tuna package has been upgraded to upstream version 0.10.4, which provides a number of bug fixes over the previous version. (BZ#1029591)

This update also fixes the following bugs:

  • Previously, if the scheduler priority was not specified, the "tuna -t $PID -p OTHER" command failed with the following error:

    ValueError: invalid literal for int() with base 10: 'OTHER'

This error occurred also when different parameters, such as RR or FIFO, were passed to the -p option. This bug has been fixed and the value error no longer occurs. (BZ#1035795)

  • Due to a bug in the tuna package, the "tuna -CP" command failed to list processes, returning the following message:

    NameError: global name 'cgroups' is not defined

This bug has been fixed and the name error no longer occurs when executing "tuna -CP". (BZ#1059685)

Users of tuna 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 https://access.redhat.com/articles/11258
