→ there still seem to be invalid null pointer references in iTALC on Linux.
→ UCS@school 4.0 R2 v2 (or v3) was in use
→ Seen on a customer system

+++ This bug was initially created as a clone of Bug #38413 +++

In several UCS@school test environments numerous segfaults of the UCS@school computerroom module were noticed:

root@slave81:~# dmesg | grep segfault | tail -1
[125430.710625] univention-mana[24783]: segfault at 0 ip 00007f86125ef16b sp 00007f85ef8107d8 error 6 in libc-2.13.so[7f8612566000+182000]
root@slave81:~# dmesg | grep univention-mana | grep -c segfault

When raising the debug level of the UMC modules to 4, the segfault vanished but reappeared when lowering the debug level back to 2.
After enabling core dumps in the UMC server and UMC modules, I were able to catch a core dump of the UCS@school computerroom module that gave interesting information:

See bug 37280 on how to enable core dumps for UMC components. I added 
"ulimit -c unlimited" to /etc/init.d/univention-management-console-server and checked the limits of the UMC module after restarting the UMC server and opening the first UMC module (limit should be "unlimited"):

root@slave81:~# pgrep -f univention-management-console-module
root@slave81:~# cat /proc/24205/limits | grep core
Max core file size        unlimited            unlimited            bytes     

Next I tried to trigger the segfault. The core file of the module process could be found as "/core".

It looks like it is not assured that the frameBuffer is already allocated when handling the first messages comming from the iTALC Windows client.
Comment 1 Sönke Schwardt-Krummrich univentionstaff 2015-12-21 11:59:21 CET
It would be helpful, if this seg fault is either reproducible or if it is possible to grab a core dump of the seg fault.
Comment 2 Sönke Schwardt-Krummrich univentionstaff 2015-12-21 12:18:02 CET
Checked systems of another customer and found the same and a bunch of additional segfaults in libItalc* during the last 10 weeks on several customer machines. List is sorted by fault address:

I could reproduce one segfault by just switching the room twice to the same room as before (→ seems Bug #27534 occurs again).

The python-notifier timer with the update() job is called after the connection is closed which results in the segfault.

Code change looked ok, but functional test revealed that the change caused segfaults during computerroom/room/acquire if a new exam is started. Therefore the commit has been reverted:
