FixesEdit

  • CRIU binary couldn't be installed independently from man pages
  • Root dir ignored in install: target
  • Bug in restoring PPC floating point register
  • SYSVIPC shmem was not attached on restore with PPC
  • AIO ring ID was erroneously close()-d
  • After dump+kill tasks remained in zombie states
  • Race in zombies vs proc proxy tasks deaths resulted in restore spurious failure
  • Restore got stuck when CRIU was called with blocked SIGCHILD
  • Wrong page size value could be used on some ARM compilations
  • Potential memory corruption when restoring an LSM profile
  • Opened /dev/kmsg in WRONLY mode failed the restore
  • Weird paths on tmpfs caused tar to fail
  • Temporary cgroup mount set (cgyard) got propagated into the host tree
  • Restore of inherited shared pipe failed
  • Spaces, tabs and backslashes in mountpoints' paths caused dump to fail
  • Tmpfs mounted with empty source caused dump to fail
  • The criu.pc file contained bad version when built from tarball
  • Deprecated -n option found in docs
  • On aarch64 the maximum virtual address available for user-space was wrongly hardcoded
