Description Thomas Haller 2023-01-27 20:33:17 UTC 
The test is here: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/9934be52cd453202248cb5f7f7dadbe05a2412de/src/core/tests/test-l3cfg.c#L340

The test exists for a while, and it appeared to run stable. No issues in gitlab-ci, in copr builds, in beaker builds (or on my machine).


Note that this is a randomize test, that means it takes different code paths depending on NMTST_SEED_RAND environment variable. Also note that on my machine I always run unit tests with randomization enabled (by setting the seet to empty `NMTST_SEED_RAND=`). I didn't notice a failure so far.

However, in the gitlab-ci test script there is a bug, so that the test effectively run always with the same seed `NMTST_SEED_RAND=0`. This is about to be fixed, and the test start failing with certain randomizations.

This needs fixing.


Here is a run that shows the failure: https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/pipelines/794971


In the meantime, I disabled the test. To reproduce, you first need to re-enable it. If you cannot reproduce on your machine, try in gitlab-ci.
