The sctp selftest is very slow on debug kernels.
I think there may be something more going on here? :(
For reference net-next-2024-08-27--12-00 is when this fix got queued:
https://netdev.bots.linux.dev/contest.html?executor=vmksft-nf-dbg&test=nft-queue-sh
Since then we still see occasional flakes. But take a look at
the runtime. If it's happy the test case takes under a minute.
When it's unhappy it times out (after 5 minutes). I'll increase
the timeout to 10 minutes, but 1min vs 5min feels like it may
be getting stuck rather than being slow..
Yes, its stuck. Only reason I could imagine is that there is a 2s
delay between starting the nf_queue test prog and the first packet
getting sent. That would make the listener exit early and then
socat sender would hang.
As the root cause for this latter hang-up looks unrelated, and this
patch is improving the current CI status, I'll apply it as-is.
The other issue will be fixed by a separated patch.
Thanks,
Paolo
