sparc64: SLAAC not working with bsd.rd

[Klemens Nanni-2]

The latest snapshot's ramdisk fails to configure IPv6 addresses
automatically after setting the AUTOCONF6 flag on my T5220's egress
interface.

        apu2# tcpdump -ni vether0 'ip6[40] = 133 or ip6[40] = 134'
        tcpdump: listening on vether0, link-type EN10MB

So far no router solicitations have been seen on the wire coming from
that machine, router advertisments seem to be ignored as well.

Running snapshots on my APU2 router, I can spin up the latest amd64
ramdisk in a VM, add it's interface to my LAN bridge and confirm that
SLAAC is working (same thing works with a VM on my X230 connected to
different networks):

        apu2# vmctl start rd -i 1 -b ./bsd.rd
        apu2# ifconfig bridge0 add tap0
        apu2# ifconfig tap0 inet6 autoconf
        apu2# vmctl console rd
        rd# ifconfig vio0 inet6 autoconf

        21:16:53.270141 fe80::f384:dbb3:8b49:a3d2 > ff02::1: icmp6: router advertisement
        21:17:24.789342 fe80::c32f:9550:4366:d5e2 > ff02::2: icmp6: router solicitation

        rd# echo nameserver fd00::1 >/etc/resolv.conf
        rd# ping6 -c1 cdn.openbsd.org | sed 2!d
        64 bytes from 2607:fae0:245::: icmp_seq=0 hlim=57 time=42.059 ms

Manually configuring both GUA and ULA in the sparc64 installer works and
I can fetch sets to proceed with the setup.

SLAAC is fully functional with the installation on disk, no issues in
production.

The output below is taken from the installer on the T5220 before
manually configuring addresses and completing the installation.

You mean this used to work (when?) or you mean this is the first time
you tried?

Can you get the normal slaacd onto the install medium and run it with
-dvv please?

Either ftp it onto the ramdisk after you have boot it access it
from the installed root filesystem in the ramdisk (i.e. /mnt/sbin/slaacd -dvv).

You will have two slaacds running who might fight amongst each other
but for debugging purposes this doesn't matter.

Thanks,
Florian

On the router:

Can you start the slaacd from the ramdisk by hand

... bsd.rd never had slaacd until now:

OK?
