RHBA-2013:1634 - libqb bug fix and enhancement update

Synopsis

libqb bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated libqb packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.

Description

The libqb packages provide a library with the primary purpose of providing high performance client server reusable features, such as high performance logging, tracing, inter-process communication, and polling.

The libqb packages have been upgraded to upstream version 0.16.0, which provides a number of bug fixes and enhancements over the previous version, including a patch to fix a bug in the qb_log_from_external_source() function that caused the Pacemaker's policy engine to terminate unexpectedly. (BZ#950403)

This update also fixes the following bug:

• Output of the Blackbox window manager did not contain logging information if the string's length or precision was specified. This affected usability of the Blackbox output for debugging purposes, specifically when used with the Pacemaker cluster resource manager. The problem was caused by bugs in the libqb's implementation of the strlcpy() and strlcat() functions and the code responsible for the Blackbox log formatting. This update corrects these bugs so the Blackbox output is now formatted as expected. (BZ#889299)

Users of libqb are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
