ifa_add_loopback_route: insertion failed with ifconfig wlan0 up
Hi, I've installed FreeBSD 8.2-RELEASE on soekris net4801 with Atheros 9280 (mini pci card) as an access point using hostapd, so far it works . Sometimes I need to disable wireless with ifconfig wlan0 down but each times I run ifconfig wlan0 up, the kernel produces this error ifa_add_loopback_route: insertion failed is this a problem ? or maybe there is a better way to disable/enable wireless ? TIA, Regards. ___ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to freebsd-net-unsubscr...@freebsd.org

If yes how it behaves with one link failure, in particular if interface is down? From what you said here it seems that your looking for lagg(4) with configured with the loadbalance option. Give this man page [1] a thorough read and youll probably see what your looking for. 1) http://www.freebsd.org/cgi/man.cgi?query=lagg about multiply GWs: you can set multiply gw via setfib(1) utility and use fib in your firewall rules. But it is not very handy with DHCP and rc(8) (setfib is located in /usr/bin and can't be used in /etc/rc.d). Due to this I have to add another FreeBSD box to handle dynamic routes. This is the one thing I know which can I do in linux easily and in freebsd with hacks. -- Regards, J. Hellenthal JJH48-ARIN 0x89D8547E I don't think lagg(4) will work here, as its designed for two interfaces that are attached to the same network (see the example in the man page). For two different ISPs, I think the setfib approach is probably the way to go. -Proto Actually I think the OP is asking about the options RADIX_MPATH feature. 1) Yes, It can balance over the two links but only using Modulo-N Hash (RFC2991) algorithm, and probably you should setup NAT on both links. 2) AFAIK there is no dead gw detection code yet. 3) Yes you can do that. There were some fixes for handling interfaces with no-link but I was not able to see it working in my setup. e.g. the host still tries to send traffic to a interface with no link, effectively blackholing the traffic (this was tested on a soekris box with if_vr(4)) IMHO the whole RADIX_MPATH stuff is still in experimental stage and needs some more work to work correctly. There is a recent thread about some improvements in RADIX_MPATH.

ip_forward / ip_output / RTFREE?
Hi,
in sys/netinet/ip_output.c at the end of ip_output:
done:
if (ro == iproute ro-ro_rt !nortfree) {
RTFREE(ro-ro_rt);
}
ro-ro_rt gets freed, if not from flowtable.
but in sys/netinet/ip_input.c, ip_forward after ip_output is called:
error = ip_output(m, NULL, ro, IP_FORWARDING, NULL, NULL);
if (error == EMSGSIZE ro.ro_rt)
mtu = ro.ro_rt-rt_rmx.rmx_mtu;
if (ro.ro_rt)
RTFREE(ro.ro_rt);
first the mtu is saved an the it will be freed.
so:
*) double free? - mtu could be invalid?
*) could also free a flowtable entry?

IPv6 neighbor discovery bug in HEAD
Hello, It looks like IPv6 neighbor discovery, due to recent changes, doesn't work correctly for me on HEAD. I don't fully understand the nature of the problem (which obviously results in connectivity problems with neighboring hosts), but the most obvious symptom is missing ethernet addresses in Neighbor Advertisement packets (which might come from interpreting a MAY be omitted in RFC 2461 7.2.4 as a MUST), perhaps because the sending code wrongly assumes the receiving end already has knowledge of the ethernet address that's being looked-up. I only have 1 -current machine so I can only say that the bug may be triggered by it having multiple IPv6 addresses used for jails, as below: re0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST metric 0 mtu 1500 options=389bRXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC ether 00:1c:c0:c3:40:e9 inet 193.56.58.97 netmask 0xfff0 broadcast 193.56.58.111 inet6 fe80::21c:c0ff:fec3:40e9%re0 prefixlen 64 scopeid 0x1 inet6 2a01:e35:8b50:2c40::2 prefixlen 64 inet 192.168.0.2 netmask 0xff00 broadcast 192.168.0.255 inet 192.168.0.4 netmask 0x broadcast 192.168.0.4 inet6 2a01:e35:8b50:2c40::4 prefixlen 128 inet 192.168.0.3 netmask 0x broadcast 192.168.0.3 inet6 2a01:e35:8b50:2c40::3 prefixlen 128 inet 192.168.0.6 netmask 0x broadcast 192.168.0.6 inet6 2a01:e35:8b50:2c40::6 prefixlen 128 nd6 options=21PERFORMNUD,AUTO_LINKLOCAL media: Ethernet autoselect (1000baseT full-duplex) status: active Example incomplete packet: 23:19:18.702622 IP6 (hlim 255, next-header ICMPv6 (58) payload length: 24) 2a01:e35:8b50:2c40::6 2a01:e35:8b50:2c40::7: [icmp6 sum ok] ICMP6, neighbor advertisement, length 24, tgt is 2a01:e35:8b50:2c40::4, Flags [router, solicited] I've tried various tricks like forcing tlladdr to 1 in nd6_nbr.c, to no avail...
