Good :) I guess I'll submit the patch after I've done some more test myself. > of course I found a new topic where problems could be: > radvd can send packets on unicast tunnels, too. > so auto configuration should be possible even via the tunnel? Yes, in theory at least. In practice there might be all kinds of nasty routing problems if you start sending RAs over the tunnel. Since the tunnel isn't a real device it will need a new route to the tunnel endpoint after encapsulation. If we then have default routes both over the tunnel interface and the underlying (physical) interface, the routing might behave quite strangely (if at all). > with tcpdump on the sending side I can see: > 14:41:57.875956 fe80::209:5bff:fe2f:ea7e > ff02::16: HBH (rtalert: > 0x0000) (padn)icmp6: type-#206 [hlim 1] (len 36) > 14:41:58.884853 fe80::209:5bff:fe2f:ea7e > ff02::16: HBH (rtalert: > 0x0000) (padn)icmp6: type-#206 [hlim 1] (len 36) > 14:42:10.705953 fe80::209:5bff:fe2f:ea7e > ff02::16: HBH (rtalert: > 0x0000) (padn)icmp6: type-#206 [hlim 1] (len 36) > 14:42:11.717831 fe80::209:5bff:fe2f:ea7e > ff02::16: HBH (rtalert: > 0x0000) (padn)icmp6: type-#206 [hlim 1] (len 36) > > but I'm not receiving anything.

Would you mind sending me your radvd.conf file, so I might try testing with a similar setup? > btw: I saw one kernel panic with ip6 tunnel and xfrm in the > call trace (but I don't have a copy and it was incomplete anyway), > so there could be some proplem left. But could be in xfrm. Can you reproduce it, or at least describe what you did to get the panic?
