Hi Dave!

I noticed some erratic behavior when doing "ip -6 r". I traced the problem
to rt6_dump_route() where we typecast NLMSG_DATA() to a rtmsg without
checking the size of the netlink message first. Seems like ip only passes
a rtgenmsg to the kernel when it does a dump, so we end up reading pure
garbage when we interpret it as a rtmsg. Please apply the patch!

Thanks a lot Ville, I will review your patch a bit more and
most likely apply it later today.
