Optimizations/improvements[edit]
- Invisible files restore is de-serialized
- VMAs restore performance is improved significantly
- Mappings of the same file re-use the descriptor, not re-open it every time
- Not-COW-ed mappings are restored in-place and are not mremmap()ed
- Empty RO mappings are mmap()ed as such and thus not re-mprotect()ed at the end
- More verbosity in case TCP locking fails (#292)
- More verbosity in case VDSO magic mismatch
- Restore or legacy epoll target descriptors and fsnotify marks is unified with common case
Bugfixes[edit]
- Restoring fanotify marks from old images (<1.3) dropped the mark
- Binfmt_misc mount could be mounted into wrong place
- Compilation failed with gcc 6.3.0 (#315)
- Waiting helpers could race with sigchild handler and would result in restore failure
- Missing VVAR page in 32bit tasks wasn't skipped and resulted in restore failure
- After restore consumption of files is increased (was fixed as side effect of mmap optimization)
Deprecation/Removal[edit]
- Deprecated separate images for fsnotify marks
