Bug 251028 – net-wireless/wpa_supplicant - wpa_supplicant: segfault at 48 ip 41f63d sp 7fff3a2267e0 error 4 in wpa_supplicant[400000+52000]

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Gabor Garami 2008-12-15 14:44:54 UTC]

If NM starts the wpa_supplicant, then it segfaults. Tested with 0.5.7 and 0.5.10.

Reprod:
 - Start NetworkManager
 - Click on some network from applet (unencrypted, WEP or WPA)
 - Enter the pass, then the icon switch to connecting and disconnected state. Syslog reports segfault from wpa_supplicant.

This is MSI Ex600X notebook, and wpa_supplicant is works very well with baselayout scripts. Only the NetworkManager have a problem.

If you do not have rights to assign bugs then you should not CC random people.

What exact command does nm issue that makes wpa_supplicant segfault? Can you reproduce it and collect a gdb backtrace?

[Comment 7 Steev Klimaszewski (RETIRED) 2008-12-16 16:31:05 UTC]

Can you test the 0.6.x wpa_supplicant as well?  And could you post the output of emerge -pv wpa_supplicant

[Comment 8 Gabor Garami 2008-12-18 09:32:23 UTC]

My laptop is crashed from some other causes, but when it works again, i will post the required outputs

darkside: sorry
Jeroen: wpa_supplicant -g/var/run/wpa_supplicant.pid <- This is a commandline, what starts.

Steev: I didn't tried 0.6.x branch. If it fails again, I will do it.

Btw, Ccache can cause my problems?

[Comment 9 Gabor Garami 2008-12-27 22:06:07 UTC]

I cannot reproduce this problem on my new system on my laptop. I don't know what can happened. 

[Comment 10 Bjarke Istrup Pedersen (RETIRED) 2009-04-15 22:02:41 UTC]

Would you try it with a 2.6.29 version of gentoo-sources and wpa_supplicant-0.6.9 and see if it works?

[Comment 11 Gabor Garami 2009-04-24 10:44:10 UTC]

I'm currently stopped using NM for network handling and I must consolidate my laptop now, because is there a very unstable NM too. I'll report if i found a solution...
