Since 042stab056.8:

  • Rebased to 2.6.32-220.17.1.el6 RHEL6.2 kernel (security and bug fixes, see link below)
  • [ovs] Open vSwitch support is complete and enabled
  • [ext4/xfs] warnings were added to detect a situation when direct reclaim tries to write writeback pages
  • [block] sleep while atomic has been fixed (bug introduced in 56.8 kernel)
  • [mm] several enhancements on direct reclaim and writeback joint work
  • [cpt] CT restore could hang in case of any cpt error handling (PSBM-13440)
  • [cpt] deleted /dev/zero file handling has been enhanced during cpt, fixing migration failures on recent kernels. (PSBM-13440)
  • [cpt] mount namespaces (for Fedora 17) checkpoint/restore support has been added (PSBM-13004)
  • [scheduler] idle time stat reported by /proc/stat has been corrected (PCLIN-30773)
  • [scheduler] scheduler bug report has been corrected to print proper calltrace
  • [ipv6] deadlock on network interface shutdown fixed (PSBM-13449)
  • [watchdog] prohibit access to hardware watchdog devices from inside CTs (#2286)
  • [mm] BUG_ON on freeing a writeback page has been fixed (PSBM-13075)
  • [fuse] some fairness in handling writeback has been added (PSBM-13465)
  • [mm] dirty pages reclaim process now can be interrupted by SIGKILL to appropriate process. This will help in case the underlying fs is stuck. (PSBM-13566)

Online migration of a Fedora 17 CT with _empty_ mqueue fs mounted is supported (at the moment we do not know who uses mqueue fs in real life). If mqueue mount is not empty - the online migration fails (PSBM-13213)
  • [cpt] a kernel panic has been fixed
