RHBA-2014:1508 - corosync bug fix update

Synopsis

corosync bug fix update

Type/Severity

Bug Fix Advisory

Topic

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

Description

The corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.

The corosync packages have been upgraded to upstream version 1.4.7, which provides a number of bug fixes over the previous version. (BZ#1055584)

This update also fixes the following bugs:

  • If the cpg clients on active cluster nodes terminated while corosync on one of the nodes was paused, corosync did not update its internal information about cpg clients on other nodes properly after resuming. Consequently, that node considered the terminated cgp clients to be still up and running. This update modifies the cpg code to ensure that corosync properly updates information about the cpg membership in this situation. (BZ#1067043)

  • Previously, corosync terminated unexpectedly with a segmentation fault when started on a system with the /dev/shm device full. This happened because the corosync logging system, logsys, could not be properly initialized. This update improves handling of the logsys initialization, and corosync now displays an appropriate error message and exits gracefully if logsys cannot be initialized. (BZ#1011307)

  • Due to a list corruption bug in the Corosync Closed Process Group (CPG) API, corosync could terminate unexpectedly with a segmentation fault under some circumstances. To fix this problem, corosync has been modified to handle the CPG init and list removal functions in the same thread. (BZ#1025321)

  • Previously, corosync could abort without logging an error properly if it was unable to store a file to the user's file system. With this update, corosync now properly verifies whether a "blackbox" can be stored on the file system. A failure of a ring ID store operation is no longer handled by assert but corosync now tries to log an error and then exits gracefully. (BZ#1005179)

  • Previously, when using the InfiniBand Architecture (IBA) as a transport protocol for corosync, corosync could not properly handle the restart of the IBA subnet manager (SM). If the IBA SM was restarted, corosync was not able to start or became unresponsive if it was already running. A series of patches addressing this problem has been applied to corosync, and it now works properly as expected in this scenario. (BZ#1001210)

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