RHBA-2012:1463 - procps bug fix update

Synopsis

procps bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

The procps packages provide a set of system utilities to provide system information using the /proc file system. The procps package includes the free, pgrep, pkill, pmap, ps, pwdx, skill, slabtop, snice, sysctl, tload, top, uptime, vmstat, w, and watch utilities.

This update fixes the following bugs:

  • Prior to this update, the 'si' and 'so' values were always zero for "m" or "M" units. This was caused by an arithmetic precision loss in the expressions used for the calculations. This update modifies the expressions to avoid precision losses. (BZ#851664)

  • Prior to this update, the vmstat tool could be terminated unexpectedly raising the SIGFPE exception when the total sum of 'us', 'sy', 'id', 'wa' and 'st' values returned by the kernel was zero. This situation could only appear on certain specific platforms. this update modifies the internal evaluation so that the vmstat tool is more robust and does no longer terminate. (BZ#875077)

All users of procps 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/knowledge/articles/11258
