tests/int: skip "update memory vs CheckBeforeUpdate" on EL9

[kolyshkin]

This test case is frequently hanging recently. Might be caused by a recent kernel update from 5.14.0-427.33.1.el9_4.x86_64 to 5.14.0-427.37.1.el9_4.x86_64.

Could not reproduce locally.

Let's skip it for now.

Fixes: #4454

OK, it's not this test, it's probably the next one.

close/reopen to kick CI

This seems to fix almalinux-9, but ubuntu failed with:

=== RUN   TestSeccompPermitWriteConditional
    seccomp_test.go:153: unexpected error: unable to start container process: unable to start init: fork/exec /proc/self/fd/7: permission denied
--- FAIL: TestSeccompPermitWriteConditional (0.13s)

which doesn't seem like a flake :-/

Oh, that is fixed by #4452 :)

LGTM.

It would be great to report the issue to upstream, but we need to have a working CI meanwhile. Do you know where to report it? Maybe some redhat thingy? Or just fedora?

[kolyshkin]

OK, ran it a few times and it looks like it's working. The issue is something about OOM killer and for some reason it's only revealing itself on Cirrus CI. I will debug it further but for now we should just skip the test.

If we're still talking about the hang, I need more time to look into it. Maybe this is something about Google cloud instance being used, or some Cirrus CI, or something else, but I can't repro it locally so probably it's not about Alma Linux 9 or the new kernel per se.

In Cirrus CI, you can have a terminal to debug, and I used that; the problem is soon after the tests hang, terminal hangs as well. I will keep looking into it.

Makes sense. Thanks a lot!
