[pkg-wpa-devel] Bug#488723: wpa_supplicant issues with bridged interface

[prosolutions at gmx.net]

Package: wpasupplicant
Version: 0.6.3-2


I am not certain whether this bug is caused by wpa_supplicant or ifupdown.  When wireless interface wlan0 is configured and then a bridged interface is created on the system using:

 brctl addbr br0
 brctl addif br0 wlan0
 ifconfig wlan0 0.0.0.0
 ifconfig br0 <ip_address> <netmask>
 route add default gw <gw_addr>

Everything works fine for a short while: ifconfig shows br0 and wlan0 is present but no IP address is assigned to it.  Network connectivity is totally fine.  Then, after about 5 minutes, I start to see stuff like this in /var/log/syslog, repeating over and over again.  At this point network connectivity is lost.
