New features[edit]

Optimizations/improvements[edit]

  • Use service FD for transport sockets on restore
  • Ability to turn pagemap-cache off (some kernels are buggy)
  • The criu --help text has become better

Fixes[edit]

  • R/O-mounted root could block the dump
  • Restore of cgroup.mm.oom_control could fail
  • Cgroup fs bind mounts were detected with error
  • Unaligned futex-es in parasite could cause dump to crash
  • When compiled with gcc-4.9 parasite code crashed
  • Failure to freeze cgroup didn't result in aborting of dump
  • Wrong ns list was parsed when dumping userns (invisible since nesting works only for mntns)
  • Non-inheritable non-tty as stdin caused shell-job restore to erroneously fail
  • Error path in criu dedup could crash

Deprecated[edit]

  • Per-pid rlimit, itimers and posix-timers
  • Separate image for epoll tfds (target file descriptors)
