RHBA-2011:0764 - corosync bug fix update

Synopsis

corosync bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated corosync packages that add features and fix 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.

This update fixes the following bugs:

  • Multicast emulation caused an extra delay to the multicast packet transmission, causing unnecessary retransmission of the packet. This update adds the "miss_count_const" constant allowing the user to specify how many times a message is checked before retransmission occurs. (BZ#619496)

  • When denied permissions from SELinux, corosync failed with a segmentation fault. Corosync now passes an error back to the API user when it is unable to create a connection between the server and client instead of causing a segmentation fault. (BZ#619918)

  • When provided an invalid multicast address, corosync failed without errors. This is now fixed, thus corosync displays an error when given an invalid multicast address. (BZ#613836)

  • Corosync client libraries delayed for 2 seconds before they displayed an error on a shut down. This is now fixed, thus the exited flag value before and after sem_wait is checked. If the value is true, ERR_LIBRARY displays. (BZ#639023)

  • The default TTL value in multicast was 1, preventing use on a routed network. The TTL value is now configurable in the corosync configuration file, thus multicast can now be used on a routed network. (BZ#640311)

  • BZ#640311 introduced a regression. (BZ#684920) (BZ#684930)

  • Shared memory no longer is leaked if the corosync server unexpectedly exits while connected to corosync clients. (BZ#665165)

  • Running multiple instances of corosync simultaneously would succeed, causing local node errors. This is now fixed to prevent initialization of multiple instances of corosync. (BZ#626962)

  • If cman ran the corosync init script, it would cause the corosync init script to be blocked. This is now fixed to allow corosync to create a Pid file and to allow cman to run corosync. (BZ#614104)

  • Corosync was unable to capture system events and notify the user about them. With this fix, SNMP MIB and daemon are added for system event notification via DBUS and SNMP. (BZ#629380)

  • Member objects in corosync were not found due to validation failure. This is fixed with an addition to the objdb file, thus validation for SNMP/DBUS integration is now successful. (BZ#675859)

  • The corosync build contained invalid version information, which caused rpmdiff to warn the user about version information changes. This was fixed, thus pkgconfig files are now correctly configured to display version as 1.2.3. (BZ#675741)

  • Corosync rebuilds succeeded only on fresh installations due to a regression issue. This is now fixed, thus corosync now rebuilds on existing installations as well. (BZ#680258)

  • A ring id file smaller than 8 bytes caused corosync to abort. This was fixed by recreating the ring id file, thus corosync now does not abort due to the ring id file. (BZ#675099)

  • Inconsistent cluster.conf files amongst nodes caused a memory leak. This is now fixed, thus a configuration reload via cman_tool no longer causes a memory leak. (BZ#677975)

  • During the recovery phase, aisexec exited unexpectedly, resulting in a lost network token. This is now fixed, thus aisexec no longer exits due to a lost token. (BZ#675783)

  • UDPU transport is added, which simulates multicast via UDP unicast. This adds a third transport option to broadcast and multicast in a cluster. (BZ#568164)

  • Fix abort that happens in rare circumstances during shutdown. (BZ#688691)

All users of corosync are advised to upgrade to these updated packages, which resolve this issue.
