We have a new faster NIPA setup, and now on non-debug builds we see a few (4 a week to be exact) flakes in conntrack_reverse_clash.sh List of flakes from the last 100 runs: https://netdev.bots.linux.dev/contest.html?pass=0&test=conntrack-reverse-clash-sh Example: # selftests: net/netfilter: conntrack_reverse_clash.sh # Port number changed, wanted 56789 got 5950 # ERROR: SNAT performed without any matching snat rule # kill: sending signal to 16051 failed: No such process not ok 1 selftests: net/netfilter: conntrack_reverse_clash.sh # exit=1 Looks like the test also occasionally flaked on the old setup ("remote" column with "metal" instead of "virt") which is now shut down: # selftests: net/netfilter: conntrack_reverse_clash.sh # Port number changed, wanted 56789 got 54630 # Port number changed, wanted 56790 got 25814 # ERROR: SNAT performed without any matching snat rule not ok 1 selftests: net/netfilter: conntrack_reverse_clash.sh # exit=1 so this isn't new, just more likely now.. Could you TAL when you have spare cycles? (BTW the new setup is owned by netdev foundation so I can give you access if that helps).
