--state option is missing: Unfortunately conntrack forgot to check it
that such parameter was missing and ctnetlink didn't do that check
either. That's why it resulted in an oops :(
I've just applied a patch for conntrack, refresh your working copy. So
you won't be able to reproduce that oops anymore.
Anyway I'll send a patch for ctnetlink, that checking must be done in
kernel space as well.
