First stage of finalize_restore unmaps the restorer blob, second stage detaches from processes. After first stage process tree is completely restored and processes are ready to continue run through sigreturn. This splitting allows us to execute something between these stages (e.g. restore freezer cgroup state). Signed-off-by:

CRIU sets freezer.state to "THAWED" during process tree dumping. That's why we can't simply save freezer.state file contents to cgroups image. New special function get_real_freezer_state() returns freezer cgroup state observed before CRIU dumping start. Patch puts its return value to dump file. Signed-off-by:

This one prints the /proc/pid/maps-like output, but with slightly more details.

The value of loginuid cannot be changed inside container, with the exception if it was not set yet. This value is inherited on fork() from parent. So, to restore original loginuid values for all tasks: - unset the container parent loginuid - all children will have this value unsetted - on child restore set value from dump See http://lxr.free-electrons.com/source/kernel/audit.c#L635 https://jira.sw.ru/browse/PSBM-41993Signed-off-by:

A freezer cgroup can contain tasks which will be not dumped, criu unfreezes the group, so we need to freeze all extra task with ptrace like we do for target tasks. Currently we attache and send an interrupt signals to these tasks, but we don't call waitpid() for them, so then waitpid(-1, ...) returns these tasks where we don't expect to see them. v2: execute freezer_detach() only if opts.freeze_cgroup is set calculate extra tasks in a freezer cgroup correctly v3: s/frozen_processes/processes_to_wait/ Signed-off-by: -

This patch introduces three helpers: 1) pstree_item_by_real() - search for pstree item by real pid. 2) pstree_item_by_virt() - search for pstree item by virtual pid. 3) pid_to_virt() - return virtual pis by real one. Note: pstree_item_by_virt() and pid_to_virt() will be used to migrate AutoFS. Signed-off-by:

tty_find_restoring_task will prepare control terminal (by tcsetpgrp) only if tty is master. By a chance it's possible to pick slave terminal as a control, which will refrain restoring control terminal. https://jira.sw.ru/browse/PSBM-42093Signed-off-by:

Running crit tool 4 times per test (decode, encode, decode --pretty and encode back again) is way too slow. The majority of time, as it turned out, goes on python load and arguments parsing. The en- and de-coding works pretty fast. So doing re-code logic in one python script for ALL images is way way faster -- ~1 hour vs ~1 minute on my box. Signed-off-by: -

There are loads and dumps method in pycriu.images that work with strings, instead of open()-ed files. For simplicity strings are turned into streams with io.BytesIO and the files are then pushed into regular load/dump methods. The problem is that array.array object doesn't work with io object in .fromfile/.tofile methods, so we have to read/write the data from them explicitly and use .fromstring/.tostring for arrays. With this the crit test finally passes :D Signed-off-by:
