backtrace

This is a problem when attempting to activate a wifi connection with a non-ascii, non-utf8 SSID via dbus, because NetworkManager will crash with SIGABRT. Backtrace of such a situation attached: things go wrong in complete_connection when it tries to call nm_utils_complete_generic with a NULL ssid.

The environ of the process contains only two variables: PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin and GIO_USE_VFS=local

Here's a simpler reproducer:

dshea@spectre:~$ unset LANG
dshea@spectre:~$ python3
Python 3.4.3 (default, Jun 29 2015, 12:16:01) 
[GCC 5.1.1 20150618 (Red Hat 5.1.1-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>> gi.require_version('NetworkManager', '1.0') 
>>> from gi.repository import NetworkManager
>>> print(NetworkManager.utils_ssid_to_utf8(b'test\xedng'))
None

handle illegal characters in nm_utils_ssid_to_utf8()

The problem is that in such a case, the final attempt to convert the string ends up being:

g_convert_with_fallback(ssid, len, "UTF-8", "ANSI_X3.4-1968", "?", NULL, NULL, NULL);

and that will fail if ssid has non-ascii characters. Attached a patch to add another fallback if g_covert_with_fallback fails.

Comment 2 Jan Kurik 2015-07-15 13:16:39 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)
