Description Stefan Scheler 2005-11-17 14:09:01 UTC

NetworkManager segfaults reliably when ejecting a pcmcia card or removing a wlan driver module.

Comment 1 Timo Hoenig 2005-11-17 14:18:05 UTC

Stefan, can you please try with the updated packages which can be found at [1] and report if you still see NetworkManager segfaulting.

Comment 2 Stefan Scheler 2005-11-17 14:44:22 UTC

can't install these because of dependency issues, but it is also segfaulting in STABLE.

Comment 3 Timo Hoenig 2005-11-17 14:52:00 UTC

You can neglect the dependency regarding dhcpd.

Comment 4 Timo Hoenig 2005-11-17 14:52:18 UTC

NetworkManager does not segfault with a 10.0 and the RPMS mentioned above.

Comment 5 Timo Hoenig 2005-11-17 14:59:05 UTC

Attaching a log of NetworkManager segfaulting on a box with an EDGE snapshop close to Alpha3.  Looks like some netlink issue.

Comment 7 Timo Hoenig 2005-11-17 15:04:03 UTC

Rober, do you have an idea what triggers this one?

This is wrong. HAL crashed and remained in state D. With a sane HAL, NM does crash on 10.0, too.

Comment 9 Robert Love 2005-11-17 17:04:05 UTC

No, unsure.  This is the first I have heard of this bug.

I can try to reproduce.

Comment 10 Robert Love 2005-11-17 19:01:51 UTC

It is a bug in libnl:

Fixed in NM CVS as of right now.

Packages built and submitted to autobuild.
