New features

• AArch64

  • 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

• Batched deduplication of memory images
• Packed rlimits into core image
• Packed timers into core image

Fixes

• 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 newinstance option 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)
