Description Vladimir Benes 2017-06-07 09:58:30 EDT
This bug has been created based on an anonymous crash report requested by the package maintainer.

Report URL: http://faf.lab.eng.brq.redhat.com/faf/reports/bthash/0d4dce82544d0c1fd2deeb073ed871afb1bd2e9e/
Comment 1 Thomas Haller 2017-06-07 10:30:48 EDT
It is quite unclear why the crash happens.

Maybe th/ppp-unexport-on-shutdown-rh1459579 is the right fix??
Comment 2 Thomas Haller 2017-06-07 11:17:31 EDT
Beniamino pointed out that th/ppp-unexport-on-shutdown-rh1459579 probably doesn't fix the issue. The patch still seems correct to do, so I merged it as https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=f07dca941dc327e11c4252688020d5fd0b9b3567 (after another fix).


Cause of crash still unclear.
Comment 3 Thomas Haller 2017-06-09 10:19:51 EDT
I still don't know whats the cause.

In the meantime, I backported several minor fixes to ppp code to nm-1-8:
https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=3cca3b50e28e4505f0e5f801ac0de4084ef03ba0

For lack of a better idea, I suggest to bring those patches to RHEL and close the bug as fixed. Maybe they fix it, otherwise, if it happens again, we know that the issue is not there.


Assigning to Beniamino.
Comment 4 Thomas Haller 2017-06-11 17:18:53 EDT
I was unable to determine the cause for sure. There is a chance that recent fixes (comment 3) fix the crash.

I'd like to backport to rhel-7.4, because the crash is not clearly reproducible and it would help to narrow down the search.
The patches do improve the code, I just cannot say for sure how severe the issues are without it.

Requesting blocker
