• Empty unixsk.img file appeared when dumping tasks without unix sockets
• Install procedure wasn't PEP-394 compliant
• CRIU blocking netfilter rules were added at the tail of the chain resulting in unlocked TCP connections
• Dump/Restore spurious failures when open() returned 0 descriptor
• When dumping shmem lots of zero pages were written into image files
• Ghost directory with more than zero ghost parents caused restore to fail
• Shared mount could escape to different group on restore
