Hi! What surprises me most is that a connect(...O_NONBLOCK) actually blocks: EINPROGRESS The socket is non-blocking and the connection cannot be com- pleted immediately.
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 description. /* in-kernel sockets don't generally have a file allocated to them * if all they do is call sock_create_kern(). */ if (sk->sk_socket->file) f_flags = sk->sk_socket->file->f_flags; timeo = sock_sndtimeo(sk, f_flags & O_NONBLOCK); Thanks, Guoqing _______________________________________________ Users mailing list: Users@clusterlabs.org https://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
