The socket flag cleanups that went into 2.6.12-rc1 are basically oring
the flags of an old socket into the socket just being created.
Unfortunately that one was just initialized by sock_init_data(), so already
has SOCK_ZAPPED set.  As the result zapped sockets are created and all
incoming connection will fail due to this bug which again was carefully
replicated to at least AX.25, NET/ROM or ROSE.

I'm probably to one to blame here but I don't get the point yet.
What I did was to change the bitfield based flags to use sk_flags
like this:

-	sk->sk_zapped   = osk->sk_zapped;
+
+	if (sock_flag(osk, SOCK_ZAPPED))
+		sock_set_flag(sk, SOCK_ZAPPED);
