Re: Namespaced network devices not cleaned up properly after execution of pmtu.sh kernel selftest

Linking in this thread as well - I submitted a patch to net-next with
a reproducer for just this bug. It works reliably on Grace/Grace on
v6.11 (and prior kernels already known to be affected), but I have not
had a chance to test it on other platforms yet. Let me know if I need
to adjust anything and whether it reproduces the bug on your machines.

Patch w/ reproducer:

Thanks!

Sorry, I missed that you identified the test case.

All good!

I will still plan to turn the reproducer for this bug into its own
regression test. I think there would still be value in having an
individual case that can more reliably trigger this specific issue.

Thanks,

Executing ./pmtu.sh pmtu_ipv6_ipv6_exception manually will only
trigger the pmtu_ipv6_ipv6_exception sub-case

Sorry, I missed that you identified the test case.
The split of the test is quite tangential, then.
