New features[edit]
- CRIT tool
- Ability to request CPU compatibility on instructions level only
- C/R of empty AIO rings
- More detailed errno report via RPC
- Per-feature "criu check"
- Inheriting FDs on restore
- Ability to automatically move veth device to host-side bridge on netns restore
- VT terminals support
- More user namespaces C/R stuff
- Sockets full support
- Invisible files
- TTYs
- FSnotifies
Optimizations[edit]
- TCP send queue is restored in the maximal portions allowed by the kernel
- Pre-loading sock-diag modules now happens in a more elegant way
Fixes[edit]
- Multi-threaded tasks on 64bit ARM could segfault upon restore
- When doing "check" CRIU could leave un-killed piggie task
- The --cpu-cap option argument was parsed with errors
- Incorrect handling of --cpu-cap fpu compatibility mode on restore
- Criu ignored trailing CLI arguments that resulted in usage confusions
- Irmap hints didn't include common "/" path
- When run per user request, CRIU left log and pid files belonging to root
- Mappings on AUFS could be looked up on wrong mount point
- Fixed compilation on Centos6.5
- Wrong /proc was used when reading the list of FDs to close on restore
- Race in restoring TCP established and listening sockets results in failed bind() on the latter
- Legacy ttys errorneously treated as unix98
- TTY pairs slavery setup could pick wrong peer
- For user-dump the log and pid files still belonged to root
- Task could die while being frozen thus causing dump to fail or save wrong task state
- Failures in mount points validation and sharing resolving didn't abort the dump (error arose on restore)
