WARNING at net/core/stream.c since 5.15.0-100.96.32.el9uek.x86_64 and 5.4.17-2136.318.7.1.el7uek.x86_64 #15

okmikel commented 1 year ago

I have 2 machines, one with OL7 and one with OL9. They act as gateway to the Internet and do IPV4 and IPV6 NAT.

On these 2 machines I have massive WARNINGs (every few seconds) since 5.15.0-100.96.32.el9uek.x86_64 (on OL9) and 5.4.17-2136.318.7.1.el7uek.x86_64 (on OL7).

On other machines, which do no NAT, I haven't seen these WARNINGs. Going back to kernels 5.15.0-8.91.4.1.el9uek.x86_64 on OL9 and 5.4.17-2136.317.5.3.el7uek.x86_64 on OL7 fixes the problem.

Here are the WARNINGs form OL7:

Looks like it could be related to this Ubuntu issue - https://bugs.launchpad.net/ubuntu/+source/linux-signed/+bug/2018960

tvierling commented 10 months ago

I'm sorry this report was overlooked. It appears that the corresponding Ubuntu issue was resolved with fixes from kernel.org stable trees, which UEK also pulls from.

Are you still experiencing these warns on up-to-date UEK6 (5.4.17) and UEK7 (5.15.0) kernels? If so, please reopen this issue with new context from those updated kernels.
