I spent some time investigating today the uprobes tests failure. I understand these test fail because the call to tracefs_event_enable() in check_probes returns -1. It also encounters errno=524, which is (apparently) the err number returned by seccomp when failing to load a filter. (see https://github.com/moby/moby/issues/45498)
Going deeper, I found this is failing because instance_file_write is trying to write a file in /sys/kernel/tracing/instances/cunit_test_iter/events/utest/utest_u/ (and creating the directory). I understand /sys/kernel/tracing is mounted as a tracefs. I am reading about it to understand what is going on. ** Bug watch added: github.com/moby/moby/issues #45498 https://github.com/moby/moby/issues/45498 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2055309 Title: No test suite run at built time nor as autopkgtest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libtracefs/+bug/2055309/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
