  • controller: avoid zombie children when asynchronous actions exit while a synchronous meta-data action is in progress (regression introduced in 2.1.5)
  • libcrmcommon: avoid file descriptor leak in asynchronous IPC clients (regression introduced in 2.1.3)
  • tools: crm_mon no longer crashes on some platforms when the fencer connection is lost (regression introduced in 2.1.0)
  • attribute manager: write Pacemaker Remote node attributes even if node is not cached
  • attribute manager: avoid use-after-free when remote node in cluster node cache
  • attribute manager: correctly propagate utilization attributes to peers to avoid the possibility of later being written out as regular node attributes
  • fencer: correctly parse action-specific timeouts with units other than seconds
  • fencer: avoid unnecessary timeouts when the watchdog timeout is greater than a query timeout, per-device fencing timeout, or stonith-timeout
  • libcrmcommon: don't assume next schema will validate when not transforming
  • libcrmcommon: when displaying XML, don't show "<null>" for empty attribute values, and properly escape special characters
  • scheduler: if the user specifies a timeout of 0, use the default 20s as documented
  • agents: ocf:pacemaker:SysInfo respects attrd_updater dampening
  • agents: ocf:pacemaker:HealthSMART properly handles SMART data missing temperature
  • tools: cibadmin --replace now leaves "++" and "+=" unexpanded in XML attribute values rather than wrongly treat them as 0
  • tools: cibsecret avoids possible truncation issue in process listing
  • tools: crm_attribute --node localhost or --node auto works
  • tools: crm_resource ignores resource meta-attribute node expressions for consistency with how the cluster works
  • tools: crm_resource honors rules when getting utilization attributes
  • tools: crm_verify --output-as=xml includes detailed messages
  • tools: crm_mon exits upon loss of an attached pseudo-terminal to avoid possibility of 100% CPU usage (seen when run via sudo with use_pty configured)
