Hello all, My apologies if this has already been reported, but I didn't see anything obvious with a quick search through the archives. I have a test program that behaves very similar to the existing selftest/bpf/test_verifier_log test that has started failing this week with v5.11-rc5; it ran without problem last week on v5.11-rc4. Is this a known problem with a fix already, or is this something new? % uname -r 5.11.0-0.rc5.134.fc34.x86_64 % pwd /.../linux/tools/testing/selftests/bpf % git log --oneline | head -n 1 6ee1d745b7c9 Linux 5.11-rc5 % make test_verifier_log ...
