[LU-16850] socklnd: ksocknal_shutdown() ASSERTION( net->ksnn_interface.ksni_nroutes == 0 ) failed

Sat, 17 Jun 2023 05:39:19 +0000

This showed up in Janitor testing for ~~LU-16709~~ patch, https://review.whamcloud.com/50530/

The sanity-lnet test introduced in that patch causes Janitor to run tests on that specific test ~20 times exercising the touched test only. All of these runs failed on the same assert.

Running the same test as part of full sanity-lnet suite execution doesn't trigger the assertion failure. Local testing also failed to reproduce the issue.

The assertion implies incomplete clean-up of socklnd peer on NI shutdown or, less likely, memory corruption.

It needs to be determined whether the issue causing the assertion to fail is introduced by LNet code changes ~~LU-16709~~ patch or only discovered by the test changes introduced in the same patch.
