This one is from Fedora 33, not CentOS 7 (from https://github.com/opencontainers/runc/runs/1875101628?check_suite_focus=true):

Seems that the task being restored receives SIGTERM. It might happen because of systemd. Same cgroup is used for all tests, and there might be a case where runc ask systemd to remove the cgroup, hits the timeout (1 second) and continues.

time="2021-02-10T19:11:05-08:00" level=warning msg="Timed out while waiting for StopUnit(runc-test_busybox.scope) completion signal from dbus. Continuing..."
time="2021-02-10T19:11:05-08:00" level=error msg="remove /sys/fs/cgroup/system.slice/runc-test_busybox.scope: device or resource busy"

So, bats runs the next test case, while systemd (allegedly) still tries to remove the cgroup, but terminating its processes.

A potential workaround is in #2757 (last commit adds a random number to cgroup name).

Randomizing cgroup names and systemd unit names did not help:

Could you try to trace signals and find out who kill a restored process?
ls -l /sys/kernel/debug/tracing/events/signal/enable
Run tests
cat /sys/kernel/debug/tracing/trace

For some reason I can't repro it locally anymore.

With tracing on, I ran the test 5 times, each time is 400 iterations, and never caught it.

With tracing off, I ran it 3 times, also 400 iterations each, also never caught it 😞

As we're restoring the container under a different name, but into the same cgroup as the original container, there might be some kind of a race in there (just a wild guess -- I still don't have a clear understanding what's happening). Maybe trying to restore the container into a different cgroup will help. I'd try that but I can't repro :(

@rppt Any idea why the lazy page test sometimes fails with runc. @kolyshkin was able to capture a complete log. The syscall number looks strange.

Yet another failuire from today: https://github.com/opencontainers/runc/pull/2873/checks?check_run_id=2204874348

I noticed it always happens when run under systemd cgroup. My previous thoughts on why this might happen are here: #2805 (comment). This is definitely related to systemd but I'm not sure how (I guess we need to take a look at when it wants to terminate the processes in cgroup).

I think we're crearing a scope by default (unless .slice is explicitly requested). Here's a relevant doc about scope lifetime (from https://www.freedesktop.org/software/systemd/man/systemd.scope.html):

Note that, unlike service units, scope units have no "main" process: all processes in the scope are equivalent. The lifecycle of the scope unit is thus not bound to the lifetime of one specific process, but to the existence of at least one process in the scope. This also means that the exit statuses of these processes are not relevant for the scope unit failure state. Scope units may still enter a failure state, for example due to resource exhaustion or stop timeouts being reached, but not due to programs inside of them terminating uncleanly. Since processes managed as scope units generally remain children of the original process that forked them off, it is also the job of that process to collect their exit statuses and act on them as needed.

With all this, it is hard to see how systemd may decide to terminate processes in a scope. So the only possibility is when someone stops it deliberately. I'm puzzled.

@rppt Any idea why the lazy page test sometimes fails with runc. @kolyshkin was able to capture a complete log.

It would have been nice to see lazy-pages.log, or at least if it has any errors.

The syscall number looks strange.

Yeah, syscall 18446744073709551615 is a bit too much :)
@avagin, @cyrillos do you have any ideas how do we get -1 instead of a syscall number. e.g:

(00.095376) 26819 (native) is going to execute the syscall 18446744073709551615, required is 15"

Maybe we've missed interrupted syscall somewhere? IIRC when syscall get interrupted the eax is set up to -1 in return and it seems that we might be screwed the syscall somewhere. Not sure though, didn't work with criu for long already ) OTOH if it triggers with lazy pages only better to poke one who wrote the lazy pages support.

OK I think I know what happens...

  1. The test runs runc checkpoint in lazy-pages mode in background:

    runc/tests/integration/checkpoint.bats

    Line 180 in b79201f

    __runc --criu "$CRIU" checkpoint --lazy-pages --page-server 0.0.0.0:${port} --status-fd ${lazy_w} --work-path ./work-dir --image-path ./image-dir test_busybox &
  2. The test runs criu lazy-pages in background:

    runc/tests/integration/checkpoint.bats

    Line 197 in b79201f

    ${CRIU} lazy-pages --page-server --address 127.0.0.1 --port ${port} -D image-dir &
  3. The test runs runc restore.

So, all three are working in parallel: criu restore restores, criu lazy-pages listens for page faults on a uffd and fetch missing pages from runc checkpoint, who serves those pages.

At some point criu lazy-pages decides to fetch the rest of the pages, and once it's done it exits, and runc checkpoint, as there are no more pages to serve, exits too.

At the end of runc checkpoint the container is removed:

runc/checkpoint.go

Lines 67 to 69 in b79201f

if !(options.LeaveRunning || options.PreDump) {
// destroy container unless we tell CRIU to keep it
defer destroy(container)

... and destroy calls cgroupManager's Destroy:

runc/libcontainer/state_linux.go

Line 47 in b79201f

err := c.cgroupManager.Destroy()

... which, in case we're using systemd cgroup driver, calls stopUnit

runc/libcontainer/cgroups/systemd/v2.go

Line 312 in b79201f

if err := stopUnit(dbusConnection, unitName); err != nil {

... which asks systemd to stop this unit, which makes systemd to terminate the cgroup.

As the container is restored into the same cgroup and systemd unit, I guess this is how the restored task receives SIGTERM. As for why it does not always happen, I guess in most cases the systemd unit is terminated after successful restore, or before restore creates a process.

In general, I now question why we need stopUnit at all (systemd units are garbage collected -- as long as there are no processes in a cgroup, it gets removed). Removing stopUnit should also fix this flake.

The alternative fix is to set a different systemd unit name for the restored container.

Which is what #2881 implements.

This ^^^ is wrong (see #2880 (comment)) for details.
