Changes[edit]

Since 042stab063.2:

  • Rebase to 2.6.32-279.14.1.el6 RHEL6.3 kernel (security and bug fixes, see below)
  • [fuse] fixed use after free in writeback + some cleanup (PSBM-16442)
  • [fuse] invalidate_files notification implemented: in cases like lease loss fused sends special notification (FUSE_NOTIFY_INVAL_FILES) and in-kernel fuse first disables IO on files associated with given inode. Further writes to the inode are possible only after file reopen. (PSBM-16105)
  • [venet] prohibit moving venet device between network namespaces (from CT to CT0). This causes net devices renumeration on CT shutdown (#2414)
  • [cpt/delayfs] eliminate possible kernel panic in delayfs_preopen() by adding a check that fake private is valid before dereferencing (PCLIN-31310)
  • [cpt/delayfs] restore mount parameters right after successfull remount, thus eliminate possible file opens errors due to temporary network/NFS server issues (PCLIN-31286)
  • [cpt] eliminate possible kernel panic: do not restart tcp retransmit timer in case the queue is empty (#2407)
  • [cpt] do not convert errors in m(un)lock() called by cpt code. Not a fix, but related to the bug #2404
  • [mm] disable by default secure bottom-up lookup for exec areas on ia32 until Red Hat fixes the bug in fork/exec. Can be enabled back via setting 4th bit in "kernel.exec-shield" sysctl. (PSBM-15942)
  • [audit] libc:getlogin() behavior has been fixed on enter/exec inside CT (#2402)
  • [devtmpfs] devtmpfs permissions were corrected to 0755 if mounting inside a CT (PCLIN-31293, #2397)
  • [fuse] i_size value for a file not opened yet on the node has been corrected (the size from server is reported) (PSBM-15941)
  • [perf] evsel: Fix an issue where perf report fails to show
  • [cpt/posix_timers] overrun counter migration support added (PSBM-15580, #2324)
  • [network/sunrpc] a couple of kernel panics on CT stop with service vz stopped fixed (PSBM-16585, PSBM-16584)
  • [mm] possible memory corruption has been fixed by preventing reclaiming of pages in the writeback (PSBM-16442)
  • [ploop] possible deadlock on destroying map has been fixed (PSBM-16627)
