Hi Martin, Thanks for the report. From: Martin KaFai Lau <martin.lau@xxxxxxxxx> Date: Thu, 21 Mar 2024 18:39:53 -0700 > Hi Kuniyuki, > > The bpf CI has recently hit failure in the "migrate_reuseport/IPv4 > TCP_NEW_SYN_RECV" test. It does not always fail but becomes more flaky recently: > https://github.com/kernel-patches/bpf/actions/runs/8354884067/job/22869153115 > > It could be due to some slowness in the bpf CI environment but failing because > of environment slowness is still not expected. > > I took a very quick look. It seems like the test depends on the firing of the > timer's handler "reqsk_timer_handler()", so there is a sleep(1) in the test. Yes, it depends on the timing of the reqsk tiemr. > May be the timer fired slower and the test failed? If that is the case, it may > help to directly trace the reqsk_timer_handler() and wait for enough time to > ensure it is called. Sounds good. I'll give it a try. Thanks! > > This test has been temporarily disabled for now > (https://github.com/kernel-patches/vmtest/blob/master/ci/vmtest/configs/DENYLIST). > Once you have a fix, we can re-enable it again to ensure this migrate feature > will not regress. > > Thanks, > Martin
