  • Link-remap files in removed directories

Optimizations/improvements

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 sub-groups creation
• Impossible to restore cgoup mem.swappines default value
• Zombies living in orphan sessions/groups failed the restore
