Subject: [PATCH] WebSockets: ignore any messages after close has been sent and
received
We currently ignore data frames when close has been received, but we
should also ignore any frame after close has been sent and received.
Currently, if we receive two close frames we end up with the code and
reason of the second frame, while the RFC says: "The WebSocket
Connection Close Code is defined as the status code contained in the
first Close control frame received by the application implementing
this protocol."
