Eric Dumazet 351050ecd6 kcm: do not attach PF_KCM sockets to avoid deadlock ... syzkaller had no problem to trigger a deadlock, attaching a KCM socket to another one (or itself). (original syzkaller report was a very confusing lockdep splat during a sendmsg()) It seems KCM claims to only support TCP, but no enforcement is done, so we might need to add additional checks.
