New features[edit]
- C/R
- fs.mqueue.msg*_default sysctls
- Unix sockets with overwritten paths
- Link-remap files in removed directories
Optimizations/improvements[edit]
- Micro-optimization on namespace ID evaluation
- Restoring shared files uses one socket instead of per-fd ones
- More verbosity when refusing to dump a file descriptor
Fixes[edit]
- Restore could fail on openat() with ENXIO when multiple mnt namespaces get restored
- The criu exec action got broken
- Link-remap and ghost files remained on FS after restore failure
- TCP window could remain clamped after restore resulting in connection lockup/slowdown
- Dump could stuck when injecting a parasite
- The
--timeoutoption wasn't taken into account when freezing tasks using freezecg - Race in freezeing/seizing could result in lost tasks
- Memory leaks here and there on error paths
- Double free in xvstrcat (crash)
- VDSO length was mis-calculated
- Symlink on
--rootpath could make restore erroneously fail - Potential memory corruption on reading mntns images
- When restoring on systems with low pid_max limit restore could fail
- RO-protected SysV shmem segments could be restored with PROT_EXEC
- File mode of mapped file was evaluated with errors
- Restore of cgroups' mem.swappines and ..use_hierarchy blocked sub-groups creation
- Impossible to restore cgoup mem.swappines default value
- Zombies living in orphan sessions/groups failed the restore
