#18151: Hostapd hangup with barrier breaker

Comment (by owrtbug):
Hostapd (which is located in /lib/netifd/hostapd.sh) is not crashing
completely. It keeps running
so I'm sorry I can't provide a core file. After running the daemon with
"-dd" flags it can be seen
that the trouble starts after the first client deauthenticates. One can
close the connection at client
to trigger this.
{{{

}}}
Later we see these error messages
{{{
VLAN: br_addif: Failure determining interface index for 'wlanxxx0.711'
VLAN: ifconfig_helper: ioctl(SIOCGIFFLAGS) failed for interface
wlanxxx0.711: No such device
VLAN: br_delif: Failure determining interface index for 'wlanxxx0.711'
}}}
Indeed, the interfaces are still on the bridge:
{{{
breth0.711 8000.e894f6b17200 no eth0.711
wlanxxx0.711
}}}
At this state, no dhcp and no other packages are passing through the
bridge. If we kill hostapd (it
is the hostapd package, not wpad) und restart it, it is fixed for some
time. The same issue can be
seen of a TL-WA901ND, so it doesn't seem to be a hardware dependent issue.
We have the same problem
with Attitude Adjustment 12.09.
Any ideas?
