pacemaker-1.1.10-14.AXS4.2

Pacemaker is an advanced, scalable High-Availability cluster resource manager for Linux-HA (Heartbeat) and/or Corosync.

It supports "n-node" clusters with significant capabilities for managing resources and dependencies.

It will run scripts at initialization, when machines go up or down, when related resources fail and can be configured to periodically check resource health.

Security issues fixed with this release:

• CVE-2013-0281
Pacemaker 1.1.10, when remote Cluster Information Base (CIB) configuration or resource management is enabled, does not limit the duration of connections to the blocking sockets, which allows remote attackers to cause a denial of service (connection blocking).

Fixed bugs:

• Upgraded to upstream version 1.1.10.

• Pacemaker no longer assumes unknown cman nodes are safely stopped.

• The core dump file now converts all exit codes into positive 'errno' values.

• Pacemaker ensures a return to a stable state after too many fencing failures, and initiates a shut-down if a node claimed to be fenced is still active.

• The crm_error tool now supports listing and printing error symbols.

• The crm_resource command allows individual resources to be re-probed, and implements the "--ban" option for moving resources away from nodes. The "--clear" option has replaced the "--unmove" option. Also, crm_resource now supports OCF tracing when using the "--force" option.

• The IPC mechanism restores the ability for members of the haclient group to connect to the cluster.

• The Policy Engine daemon allows active nodes in the current membership to be fenced without quorum.

• Policy Engine now suppresses meaningless IDs when displaying anonymous clone status, supports maintenance mode for a single node, and correctly handles the recovered resources before they are operated on.

• XML configuration files are now checked for non-printing characters and replaced with their octal equivalent when exporting XML text. Also, a more reliable buffer allocation strategy has been implemented to prevent lock-ups.

• Previously, lsb scripts managed by Pacemaker did not cancel their recurring monitor operations correctly when stopping. Consequently, monitor operations failed after resources had successfully stopped. This bug has been fixed, and recurring monitor operations are now correctly cancelled before the lsb resource is stopped.

Enhancements:

• Added the "--ban" and "--clear" options to the "crm_resource” command so that clone, master, and slave resources can now be navigated within the cluster as expected. This allows crm_resource to move a resource as designed.

• Previously, the hacluster did not have a UID or GID reserved. Number 189, already reserved for hacluster, is now used for all installation.

• Previously, the default node name used by the crm_standby and crm_failcount commands did not always match the host names (“uname -n”) of certain cluster nodes leading to the cluster ignoring updates. Scripts now use the crm_node command instead of uname.

• Fixed the handling of return code: recovery of an expected error state is now transparent.

• Automated unfencing in Pacemaker has been added: cman's automatic unfencing does not fail any longer when combined with Pacemaker.
