New features
- New code layout for sub-projects (e.g. Compel)
- Unprivileged dump
- Dump/check cpuinfo support for PPC
- Explorers for CRIT
- Added "post-setup-namespaces" to action scripts
- Added timeout for dump procedure (5 sec by default)
- Ability to override LSM profile on restore with CLI/RPC option
- External TTYs
- External bind mounts can be fs-root mounts too
- C/R for
- Mode and uid/gid of cgroup files and dirs
- Freeze cgroup state (frozen/thawed)
- Task's loginuid
- Task's oom score
- Per-thread credentials
- Filter mode of seccomp
- Ghost file in removed directory
- Ghost files lutimes
- Binfmt-misc FS contents
- Netfilter conntracks and expectations
Optimizations/improvements
- Align parasite stack on 16 bits for correctness
- Compilation with native libc syscall wrappers and helpers
- Parasite code injection done via memfd system call
- Make vaddr to pfn conversion with one less syscall
- CRIT shows device numbers in "maj:min" manner
- CRIT shows mmap's status in verbose
Fixes
- Absent readlink syscall on ARM (use readlinkat instead) could cause dump to fail
- Wrong argument to timer_create system call could cause restore to crash
- Extra tasks in freeze cgroup caused dump to fail/hand/crash
- Unaligned restore-time object allocations caused lock operations to fail
- Opened /proc/pid dir of dead task failed the dump
- Unaligned stacks caused criu to fail on aarch64
- Changed device numbers on restore side could cause random failures
- Fixes in mount points sharing/slavery/propagation restore
- Race between mntns creation and fds closing in different tasks could cause restore to fail
- Hard kernel limit on TCP repair recv queue restore could cause big queue restore to fail
- Unconnected dgram UNIX socket with data lost packets on restore
- CRIT didn't show IPC objects
- CRIT didn't convert IP addresses in images
Security
Deprecated/removed
- Completely removed 'show' action. Use CRIT instead.
