openais bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

An updated openais package that fixes various bugs and adds one enhancement 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 update fixes the following bugs:

• Previously, the length of the array cpg_exec_service[]/cpg_exec_engine[] in
  OpenAIS and corosync differed. Consequently, OpenAIS failed if corosync ran on
  the same network. This update modifies the length of this array in OpenAIS. Now,
  OpenAIS and corosync successfully run on the same network. (BZ#708335)
  
• Previously, the receive buffers could overflow under heavy traffic.
  Consequently, packets could be lost and retransmit list error messages appeared
  in the log files. Now, incoming messages are processed more frequently, and the
  retransmit list error messages no longer appear. (BZ#718773)
  
• Previously, the OpenAIS service could, under certain circumstances, encounter
  a deadlock when starting or stopping the process. This update modifies the
  underlying source code to prevent such a deadlock. Deadlock situations no longer
  happen during a rapid start or stop process. (BZ#726142)
  
• Previously, OpenAIS could, under certain circumstances, terminate unexpectedly
  when OpenAIS was used in a network losing packets and a large number of
  configuration changes occurred. This update modifies the underlying source code,
  and OpenAIS no longer terminates under these circumstances. (BZ#729081)
  
• Previously, OpenAIS could, under certain circumstances, use an incorrect sort
  message queue when the "memb_join" message was sent during recovery.
  Consequently, OpenAIS could join all nodes. Now, OpenAIS uses the correct sort
  message queue if memb_join message is sent during recovery. (BZ#734865)
  
• Previously, openais_response_send could, under certain circumstances, change
  the value of req->ics_channel_handle. Consequently, OpenAIS terminated
  unexpectedly when using the subscribe function of the eventing (EVT) service.
  This update saves the handle outside the message. OpenAIS no longer terminates
  if an application is using the subscribe function of the EVT service.
  (BZ#737100)
  
• Previously, cman could, under certain circumstances, terminate unexpectedly on
  all cluster nodes and nodes were not fenced if the system clock was changed on a
  cluster node. Consequently, the cluster was not shut down gracefully and had to
  be rebooted manually. Now, the underlying code has been modified to handle
  significant time changes. The cman service no longer terminates and the cluster
  no longer fails. (BZ#738468)
  
• Previously, the groupd daemon often exited with the "groupd: cpg_leave error
  retrying" error message, causing OpenAIS to become unresponsive when stopping
  the cman service on a cluster node shutdown. Consequently, the cluster node was
  not shut down correctly. Now, the underlying code has been modified to stop cman
  correctly. Cluster nodes can be shut down as expected. (BZ#746807)
  
• Previously, totemip_parse used the getaddrinfo function without an associated
  freeaddrinfo call. Consequently, a small amount of memory leaked when calling
  OpenAIS. This update adds a call to freeaddrinfo. OpenAIS no longer leaks memory
  in totemip module. (BZ#752952)
  

This update also adds the following enhancement:

• With this update, manual pages for ais-keygen, aisexec, openais-cfgtool and
  openais-confdb-display have been added to OpenAIS. (BZ#703162)
  

All users of openais are advised to upgrade to this updated package, which fixes
these bugs and adds this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.
