RADVD fails to start

[poruid]

When rc.radvd start is run, it produces the following result:

/var/mod/root # /etc/init.d/rc.radvd start 
Set ipv6 address: 2001:xxxx:yyyy::1/64 already set.
Set ipv6 forwarding...done.
Starting radvd...[Dec 27 11:32:25] radvd: setsockopt(IPV6_RECVPKTINFO): Protocol not available
failed.

The syslog does not yield any extra information that would be helpfull.

I use radvd to advertise the IPv6 2001xxx:yyyy::/64 sub network prefix.
It is started after rc.aiccu has succeeded and IPv6 firewall rules have been set.
Currently my freetz revison is trunk 2920 (04.67 fw). When I ran 2887 (last 04.59 fw) before, radvd worked flawlessly.

Any ideas?
Has anyone radvd running with the 04.67 firmware?

Rebuilded from a clean checkout against r2945, but starting radvd still gives:

Jan  2 10:43:46 fritz daemon.err radvd[1865]: setsockopt(IPV6_RECVPKTINFO): Protocol not available

A google search for this error yields no hint, except that WRT has had this error with 2.4 kernels, due to defferent definitions of IPV6_RECVPKTINFO under kernel 2.4. and 2.6. The radvd socket.c source contains the system call that fails.

Can you please attach a strace log of this?

see attached output from

strace -f -r -T -v /etc/init.d/rc.radvd start

My IPv6 subnetwork prefix has been replaced with 2001xxx:yyyy.

Could you provide us please your config? Which revision do you use? Tag or trunk?

What are you looking for in my config?
The revison: devel trunk 2945, but the problem with radvd showed up when I changed from r2887 to r2920, since than all revisons I've builded, even from a fresh checkout and with a newly created config, have a non-starting radvd.

There seems to be an issue with your uclibc or something like that i think. I just wanted to clear out, if there is any config-issue. Also i would try to rebuild everything new with "make clean". Don't really think that will fix your problem, but i had often strange issues if i checked out a new version and did just a "make".

Anyhow, radvd should work like a charm. If you could provide me your .config and perhaps the config-file of your radvd, we could find an issue.

Thanks for giving us the informations...

Um mal einen alten Thread wieder aufzuwärmen: Das Problem, um das es hier ging, ist zumindest bei mir wieder da:

/var/mod/root # /etc/init.d/rc.radvd start
Starting radvd ... [Aug 20 15:19:53] radvd: setsockopt(IPV6_RECVPKTINFO): Protocol not available
failed.

Könnte das mit dem Patch aus r5476 zusammenhängen?
Config ist im Anhang.

@HAL 9000: Hast Du ein uclibc-dirclean ausgeführt? Oder mit einem frischen Checkout neu kompiliert? Damit sollte es klappen.

uclibc-dirclean hatte ich probiert, hat nichts gebracht. Nach einem make distclean gehts jetzt aber.
