Maybe it is because that the socket is created by sock_create_kern, and
O_NONBLOCK flag is not worked since __sctp_connect has the following
/* in-kernel sockets don't generally have a file allocated to them
* if all they do is call sock_create_kern().
f_flags = sk->sk_socket->file->f_flags;
timeo = sock_sndtimeo(sk, f_flags & O_NONBLOCK);
