Hi Manu, > > I was able to confirm the fix using the artifacts from https://github.com/kernel-patches/bpf/actions/runs/9905842936 > Thanks > Thanks for testing the fix. This bug has been resolved now but the test still hangs sometimes. Unfortunately, I am not able to reproduce this hang using vmtest. Can you extract some logs from the CI somehow?? If it is hanging in the kernel there should be some soft lockup or RCU lockup related messages. I was talking about this with Kumar and we think that this test is hanging in the userspace in the following loop: while (READ_ONCE(fexit_skel->bss->fentry_cnt) != 2); Could it be that fentry_cnt is > 2 somehow before we reach this?? This is only a random guess though. Thanks, Puranjay
