sctp: hold the chunks only after the chunk is enqueued in outq
When a msg is sent, sctp will hold the chunks of this msg and then try to enqueue them. But if the chunks are not enqueued in sctp_outq_tail() because of the invalid state, sctp_cmd_interpreter() may still return success to sctp_sendmsg() after calling sctp_outq_flush(), these chunks will become orphans and will leak. So we fix them by moving sctp_chunk_hold() to sctp_outq_tail(), where we are sure that the chunk is going to get queued. Signed-off-by:Xin Long <lucien.xin@gmail.com> Signed-off-by:
