Subject: [TEST] amt.sh flaking
Date: Mon, 5 Jan 2026 18:07:12 -0800 [thread overview]
Message-ID: <20260105180712.46da1eb4@kernel.org> (raw)
Hi Taehee!
After migration to netdev foundation machines the amt.sh test has
gotten a bit more flaky:
https://netdev.bots.linux.dev/contest.html?test=amt-sh
In fact it's the second most flaky test we have after txtimestamp.sh.
All the failures are on non-debug kernels, and look like this:
TAP version 13
1..1
# timeout set to 3600
# selftests: net: amt.sh
# 0.26 [+0.26] TEST: amt discovery [ OK ]
# 15.27 [+15.01] 2026/01/05 19:33:27 socat[4075] W exiting on signal 15
# 15.28 [+0.01] TEST: IPv4 amt multicast forwarding [FAIL]
# 17.30 [+2.02] TEST: IPv6 amt multicast forwarding [ OK ]
# 17.30 [+0.00] TEST: IPv4 amt traffic forwarding torture .......... [ OK ]
# 19.48 [+2.18] TEST: IPv6 amt traffic forwarding torture .......... [ OK ]
# 26.71 [+7.22] Some tests failed.
not ok 1 selftests: net: amt.sh # exit=1
FWIW the new setup is based on Fedora 43 with:
# cat /etc/systemd/network/99-default.link
