New features[edit]
- Performance improvements
- Shared entries in reg-files image
- Less accesses to
/proc/$pid/map_fileslinks - Cache for
/proc/$pid/pagemapreads - VDSO page is seeked only in anonymous mappings
- Task's auxv is read in one call
- Merged mm and vma image files for better packing
- NFS inodes' path resolution (for fsnotify) cache
- One
readlink()call when checking anon inodes - Don't dump kernel's zero-page
- Parse fast
/proc/self/mapswhen searching for hole for restorer - A bit faster write into image files with
writev()
- Library versioning
- RPC API got closer to CLI
- Suitable for live migration project
- Action-scripts via RPC notification messages
- New "post-restore" call in action scripts
- Logrotate rules file
- Default log file for service when starting via systemd
Fixes[edit]

- Badly counted pages stats on restore
- Linked remap name conflict when dump and restore on NFS
- Sporadic failures in memory draining due to huge pipes used
- Broken
criu showof repeated fields - Failure to open mountpoint in foreign pid namespace
- Unlinked bound unix socket dump error
- Small memory leak when writing to incremental image(s)
- Restoring fsnotify for links results in ELOOP
- Host's PATH is not suitable when execv-ing tar/ip/iptable to restore namespace (workaround, proper fix will be in 1.3)
