Optimizations/improvements[edit]
- Temporary proc mountpoint is mounted with nosuid, noexec and nodev
- Less memory copies when preparing restorer binary
- CRIT action "show" for less keystrokes on common use-case
- Fsnotify log messages now use hex everywhere :)
- CRIT output doesn't mix fields any more
Fixes[edit]
- 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
