[OLSR-users] Gould not find global IPv6 address (i.e. olsr becomes blind ; )

hi!

olsrd seems to have a problem to see global IPv6 addresses on an 
interface although they're definitely there and also refuses to run 
although a link local address is there.

olsrd: 0.4.8 and 0.4.9
linux: 2.6.9
ifdriver: madwifi (20050822)

# ifconfig ath0
ath0      Link encap:Ethernet  HWaddr 00:20:A6:4C:A3:31
           inet6 addr: 2002:300:200:1::100/64 Scope:Global
           inet6 addr: 2001:300:200:1::100/64 Scope:Global
           inet6 addr: fe80::220:a6ff:fe4c:a331/64 Scope:Link
           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
           RX packets:0 errors:0 dropped:0 overruns:0 frame:0
           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
           collisions:0 txqueuelen:200
           RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
           Interrupt:5 Memory:c8ac0000-c8ad0000

this is what olsrd says (DebugLevel 9):

[...]

         Scope: 0        inet6 addr: fe80:0000:0000:0000:0220:a6ff:fe4c:a331
         Scope: 32       Could not find global IPv6 address for ath0
[...]

i guess a \n was very unluckyly placed in the debug output and scope 0 
is probably global. i.e. i don't see why olsrd can't find them.
also, i don't understand why that matters. actually my intention was to 
use olsr on the v6 link local subnet.

what actually makes me wonder most, is that such a problem seems not to 
have occurred anywhere else before!? then again, that increases the 
probability that i forgot something very stupid and the problem can be 
resolved quickly... ;)

so, are these bugs? am i doing something wrong?

regards,

	Chris
