Don't mess with sysctl, just try sending queues in greedy mode shrinking the max_chunk eventually. This is needed for 2 reasons -- first, to get rig of reading the max_rshare sysctl and to make libsoccr possible and simple. Signed-off-by: -

This hook is called at the very end, when everything is restored and processes were resumed. Can be used for some actions, which require operation container, like restarting of systemd autofs services. v3: Call "post-resume" scripts before detach option check (to make sure, that restored process(es) are still alive v2: Remove code chunk, escaped from debugging Signed-off-by:

If add_cgroup_properties failed we have @ncd sitting in @match->children or @current_controller->heads list, and then we free @ncd entry leaving those lists carrying dead pointers. Add proper rollback action. Signed-off-by:

Since we're freeing list entries don't forget to initialize list then, otherwise it gets out with free entries and may hit use-after-free bug. Signed-off-by:

Previously when we've been on early stage we tried to workaround lack of prlimit libc call simply providing own implementation, but it cause problems on some libc configurations so simply use rlimit64 and __NR_prlimit64 syscall directly. The kernel must support __NR_prlimit64 syscall and provide rlimit64 structure as well. Signed-off-by:

The option was in use when we didn't have the /proc/pid/ns links and thus ns ids. Later we used it at restore time to tell which namespaces to restore the pstree into. Right now ids are always generated and this option has no effect (and meaning). Signed-off-by: -

The page server already knows how to create a TCP server and client. The code has been hidden behind static-s in page-xfer.c. This commit moves the common TCP server/client code to util.c to be able to also use it in the upcoming remote lazy-server/lazy-client userfaultfd enhanced criu. Signed-off-by:
