- Update to criu 2.5:
New features:
* C/R of fs.mqueue.msg*_default sysctls, Unix sockets with
overwritten paths, and Link-remap files in removed directories
Optimizations/improvements:
* Micro-optimization on namespace ID evaluation
* Restoring shared files uses one socket instead of per-fd ones
* More verbosity when refusing to dump a file descriptor
Fixes:
* Restore could fail on openat() with ENXIO when multiple mnt
namespaces get restored
* The criu exec action got broken
* Link-remap and ghost files remained on FS after restore failure
* TCP window could remain clamped after restore resulting in
connection lockup/slowdown
* Dump could stuck when injecting a parasite
* The --timeout option wasn't taken into account when freezing
tasks using freezecg
* Race in freezeing/seizing could result in lost tasks
* Memory leaks here and there on error paths
* Double free in xvstrcat (crash)
* VDSO length was mis-calculated
* Symlink on --root path could make restore erroneously fail
* Potential memory corruption on reading mntns images
* When restoring on systems with low pid_max limit restore could
fail
* RO-protected SysV shmem segments could be restored with
PROT_EXEC
* File mode of mapped file was evaluated with errors
* Restore of cgroups' mem.swappines and ..use_hierarchy blocked
