Checkpoint/Restore In Userspace, or CRIU, is a software tool for Linux operating system. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at.

    2015-09-11 - - Disable systemd service as a temporary workaround for possibile security issues (CVE-2015-5228, CVE-2015-5231, bsc#943105)

    2014-09-15 - - update to version 1.3.1, a stable releasing fixing below: * Sibling restore mode didn't set up CRIU signals properly * Unpredictable sibling/child root task restore. Fixed with explicit CLI option * Validation for leaf mount points was skipped * Mount options were corrupted on dump, which resulted in errors bind mounts detection

    2014-09-02 - - update to version 1.3: * Docker and LXC support, lots of bug fixes - cleanup spec file, fix rpmlint warnings

    2014-06-18 - - Update to version 1.3-rc2: * external bind mounts and tasks-to-cgroups bindings * many bugfixes in memory restore and mounpoints dump

    2014-05-06 - - Update to version 1.3-rc1: New features: * AArch64 * Multiple mount namespaces * FPU state restore control Restore old FPU state on newer CPUs Ability to ignore FPU restoration * Support stopped multi-threaded tasks * CRIU now can execv() other binary right after restore is complete * Inode-revese mapping can be enforced to allow live-migration with FS copying * Gold linker can now be used to compile CRIU * "Berserker" test to check CRIU scalability * Punch pages from mem images on restore (optimizes live-migration) Optimizations: * Batched deduplication of memory images * Packed rlimits into core image * Packed timers into core image Fixes: * Bad checks for kcmp() ret codes resulted in errors in file sharing detection * Multiple mmap-s of same files with different flags blocked the restore * Integer overflow in huge mapping restore caused restoration failure * Devpts's newinstance option was lost during dump * Subsequent dump could try to find old mem dump for newly forked task * Bad detection of overmounted mountpoints on fsnotify restore * Page-server could read partial message and failed * Errors in dumping of two subsequent anon vmas in some cases * Irmap mis-compared devices for disk FS-s * TMPFS handles always change during dump/restore * Pre-dump sometimes hangs on FIFO-s * Post-restore script fails too late (if does it)

    2014-03-01 - - Run spec-cleaner, nothing more than that.

    2014-02-26 - - Update to version 1.2: New features: * Performance improvements * Library versioning * RPC API got closer to CLI * New "post-restore" call in action scripts * Logrotate rules file * Default log file for service when starting via systemd Bug fixes: * A lot for ARM cross-compile * Fsnotifies dumping didn't work on NFS * Images auto-deduplication only worked one level up * Packet socket ID was treated as file-descriptor and close()-d * Badly counted pages stats on restore * Linked remap name conflict when dump and restore on NFS * Sporadic failures in memory draining due to huge pipes used * Broken criu show of repeated fields * Failure to open mountpoint in foreign pid namespace * Unlinked bound unix socket dump error * Small memory leak when writing to incremental image(s) * Restoring fsnotify for links results in ELOOP * Host's PATH is not suitable when execv-ing tar/ip/iptable to restore namespace (workaround, proper fix will be in 1.3) * Using subdirs in log file name via RPC breaks security - New subpackages: libcriu1 and criu-devel - Remove obsoleted always-define-ptrace_peeksiginfo_args.diff

    2014-01-28 - - Update to version 1.1: BUGs fixed, * Errors from memory dumping are not handled resulting in corrupted dumps * EOF detection in stacked images is done with error * Stacked images don't work on non-shared FS (missing pagemap-s)
