New features[edit]
- AArch64
- Multiple mount namespaces
- FPU state restore control
- Restore old FPU state on newer CPUs
- Ability to ignore FPU restoration
- Support stopped multi-threaded tasks
- CRIU now can execv() other binary right after restore is complete
- Inode-reverse mapping can be enforced to allow live-migration with FS copying
- Gold linker can now be used to compile CRIU
- "Berserker" test to check CRIU scalability
- Punch pages from mem images on restore (optimizes live-migration)
Optimizations[edit]
- Batched deduplication of memory images
- Packed rlimits into core image
- Packed timers into core image
Fixes[edit]
- Bad checks for
kcmp()ret codes resulted in errors in file sharing detection - Multiple mmaps of same files with different flags blocked the restore
- Integer overflow in huge mapping restore caused restoration failure
- devpts's
newinstanceoption was lost during dump - Subsequent dump could try to find old mem dump for newly forked task
- Bad detection of overmounted mountpoints on fsnotify restore
- Page-server could read partial message and failed
- Errors in dumping of two subsequent anon VMAs in some cases
- Irmap mis-compared devices for disk FSs
- TMPFS handles always change during dump/restore
- Pre-dump sometimes hangs on FIFOs
- Post-restore script fails too late (if does it)
