* ploop could get stuck inside ploop_make_request() causing Node to hang (PSBM-29066, {{OVZ|6293}}, {{OVZ|6392}})
* Fix for {{CVE|2015-5366}} and {{CVE|2015-5364}} extracted from RHEL6 kernel 2.6.32-573.3.1.el6 backported version of mainline commit beb39db59d1 "udp: fix behavior of wrong checksums"
+
* Under certain network workload, Container checkpoint/restore operations could result in conntrack duplication which could prevent online migration of said Container (PSBM-32411)
* fixed host hang where ploop stuck inside ploop_make_request() (PSBM-29066, {{OVZ|6293}}, {{OVZ|6392}})

* CPT image compatibility was broken in 042stab108.x kernels. As a result, received but nondelivered TCP packets saved into CPT image could, in certain circumstances, lose TCP flags during restore on 042stab108.x kernels.

Since 042stab108.8:

  • ploop could get stuck inside ploop_make_request() causing Node to hang (PSBM-29066, OVZ-6293, OVZ-6392)
  • Under certain network workload, Container checkpoint/restore operations could result in conntrack duplication which could prevent online migration of said Container (PSBM-32411)
  • Soft lockup in 'cgroup_kernel_close()' (PSBM-33300)
  • Kernel could crash in 'attach_task_by_pid()' when tasks exited. (PSBM-33381)
  • CPT image compatibility was broken in 042stab108.x kernels. As a result, received but nondelivered TCP packets saved into CPT image could, in certain circumstances, lose TCP flags during restore on 042stab108.x kernels.
