Changes

Since 042stab062.1:

  • [netfilter] iptables inability to handle > 2000 rules inside 32bit CT on 64bit node (PCLIN-31246)
  • [cpuinfo] cpuflags are reported empty inside a CT on a node with single physical cpu. In particular this breaks yum (#2373)
  • [cpt] fix raising kernel BUG() on cpt/rst of a ptraced task
  • [cpt/delayfs] NFS remote locks handling has been fixed (PSBM-14815)
  • [fairsched] a lot of scheduler enhancements mostly intended to improve performance on NUMA nodes, now tries to run CT processes on no more than vcpus configured for the CT (PSBM-14332)
  • [framebuffer] Draw Parallels logo if node is booted in graphical mode and "psbm" kernel boot option is provided (PSBM-15257)
  • [debug] added the ability to dump slab entries
  • [mm debug] added an ability to catch double free in per-cpu page lists. Triggers BUG() if double free detected.
  • [net] netlink messages handling code has been fixed (env context corrected). In particular this fixes network configuration using Network Manager (#2353, #2354)
  • [fuse] trim 'count' of bytes to read to avoid reading beyond eof when racing with writeback (PSBM-15340)
  • [fuse] one more race fixed in writeback (PSBM-15008)
  • [cpt] ipv6 module detection error message has been improved
  • [cpt] online migration failure between 2 nodes without ipv6 modules loaded/enabled has been fixed (PSBM-15431)
  • [cpt] fixed tty struct leak (PSBM-15373)
  • [mm] new sysctl has been introduced: vm.strict_mem_cpuset (=0 by default). If 0, mem cpuset will work as a hint, i.e. if allocation from allowed NUMA nodes fails, cpuset constraints will be ignored (PSBM-15613)
  • [ploop] hang on fsync() on ro mount has been fixed (PSBM-15435)
  • [fuse] a page-cache corruption has been eliminated
  • [kstat] fixed a kernel panic due to cpu hard lockup caused by a deadlock in gathering statistics code (PCLIN-31259)
