However, a bit of backstory: A day ago I used kselftest from the linux/next branch and ran it (w/o sudo). It showed me the exact same error. However, I was running a modified version of 5.3.13, but those modifications were actually trivial (5 lines changed) and shouldn't have resulted in this kernel error. So, I switched to the vanilla 5.3.13 and ran kselftest (w/o sudo) again. I ran it 3 times (w/o any errors), switched back to the modified kernel and ran kselftest (w/o root) 2 more times and everything was fine. Then I decided to test the vanilla one again for the 4th time, but this time I ran kselftest as root where this BUG popped again.

Try a kernel.org 5.3.9 and if that works, then try 5.3.13 and if that fails, run 'git bisect' and try to find the offending kernel commit. thanks, greg k-h _______________________________________________ Linux-kernel-mentees mailing list Linux-kernel-mentees@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/linux-kernel-mentees ^ permalink raw reply [flat|nested] 5+ messages in thread

I had recently compiled 5.4.1 as well so I decided to run this test against 5.4.1 (= BUG). After this I realized I had 5.3.9 kernel kept away so I decided to run the test against that too (= BUG). After 5.3.9's error something didn't feel right. Mind you I was using kselftest from linux/next so I got suspicious about the test it-self. I ran kselftest from 5.4.1 on kernels 5.4.1 and 5.3.13 and none of them resulted in the BUG this time. After a bit of digging I found out the next branch had 2 additional test cases for the tls test, and one of them (sendmsg_fragmented) is the actual culprit that was causing all this. TL;DR: tools/testing/selftests/net/tls.ci:sendmsg_fragmented from the next tree appears to be broken(?)
