Optimizations/improvementsEdit
- Code coverage collecting now works
- Use native rtnl library for netlink messages processing
- Using
--output - now results in stdout as log, not a file with the name "-"
- Signals are printed by names in logs
Make tar generated tarbal with bad name- CG restore code lacked rollback in some places
- Error code from raw syscalls was treated with errors resulting in wrong
criu check reports
- Dumping task with HUGE amount of file descriptors failed
- Task could be stopped after pre-dump if respective option was used
- A /proc/pid directory from dead process conflicting with a new alive one could cause dump to fail
- Zombie from alien session/process group caused restore to fail
- CGroup fs was wrongly mounted in CGNS on restore
- Irmap scan was mis-checking devices numbers
- Use-after-free in irmap scan
- Btrfs bindmounts detection was mistaken due to 'subvol=' options met
- Propagation of mountpoint's shared groups was lost for propagated mounts
- Unaligned allocations of restore shared memory could result in codedumps when used by futexes
- Temporary mountpoints could result in spurious propagations
- When aborting the dump criu could crash on use-after-free objects
- Locking the network could stuck doing the DNS resolve
- Several build fixes
Deprecated/removedEdit
