RHBA-2010:0665 - Bug Fix Advisory
Synopsis
openais bug fix update
Type/Severity
Bug Fix Advisory
Topic
An updated openais package that fixes various bugs is now available for Red Hat
Enterprise Linux 5.
Description
The Application Interface Specification (AIS) is an API and a set of policies
for developing applications that maintain services during faults. The OpenAIS
Standards Based Cluster Framework is an OSI-certified implementation of the
Service Availability Forum AIS. The openais package contains the openais
executable, OpenAIS service handlers, default configuration files, and an init
script.
This updated openais package provides fixes for the following bugs:
- previously, an internal protocol variable was set on retransmission when it
should only have been set on the first transmission. With this update, this
variable is only set on the first transmission. (BZ#601076)
- previously, rolling upgrade to RHEL6 resulted in a segfault error of openais f
it received cpg messages. With this update, openais proccesses cpg messages
without fault. (BZ#611930)
- previously, multicast could be delayed while sending unicast packets due to
the bahavior of many hardware switches. With this update, only required messages
are retransmitted. (BZ#624518)
All users of OpenAIS are advised to upgrade to this updated package, which
resolves these issues.
