Crash on creating ad-hoc network
Last modified: 2011-02-10 20:40:59 UTC
1. I create new network ad-hoc 2. I fill the first dialog box choosing WPA & WPA2 encryption 3. The second dialog box appear informing that network I'm about to connect is encrypted (??? - I already awere about it) and display disabled, empty dropdown list(???). All I can do is click on next. 4. nm-applet crashes Distribution: Gentoo Base System release 2.0.1-r1 Gnome Release: 2.32.0 2010-11-04 (Gentoo) BugBuddy Version: 2.32.0 System: Linux 2.6.36-zen1+ #8 ZEN SMP PREEMPT Sun Nov 14 02:05:51 GMT 2010 x86_64 X Vendor: The X.Org Foundation X Vendor Release: 10902901 Selinux: No Accessibility: Disabled GTK+ Theme: Clearlooks Icon Theme: Tango GTK+ Modules: canberra-gtk-module, gnomesegvhandler, gnomebreakpad Memory status: size: 424259584 vsize: 424259584 resident: 23941120 share: 18010112 rss: 23941120 rss_rlim: 18446744073709551615 CPU usage: start_time: 1290097857 rtime: 156 utime: 150 stime: 6 cutime:0 cstime: 0 timeout: 0 it_real_value: 0 frequency: 100 Backtrace was generated from '/usr/bin/nm-applet' [Thread debugging using libthread_db enabled] [New Thread 0x7f8915ca3710 (LWP 2695)] 0x00007f891f82702d in waitpid () from /lib/libpthread.so.0

Does creating a WEP-protected network work? As of the 2.6.32 - 2.6.34 kernel WPA Adhoc networking did not work in the kernel (the drivers said it succeeded but it showed up as WEP not WPA) so we may still have kernel issues. If a WEP protected network works, but WPA does not, then that's likely the issue. Let me know...

It does not crash with WEP.
Thanks, good to know. This is most likely an issue with NM trying to match the network that the card actually created with the one that NM wanted the card to create. It should probably fail the whole operation, but clearly NM should not crash when that happens.

After it crash I can create the network but it is unencrypted despite all indicates it is (including key in iwconfig).
It should be fixed: https://bugzilla.redhat.com/show_bug.cgi?id=632123#c12
