From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnaldo Carvalho de Melo Date: Wed, 26 Sep 2007 23:07:43 +0000 Subject: [PATCH 1/2] [DCCP]: Reduce the number of writable states Message-Id: <20070926230743.GP10932@ghostprotocols.net> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: dccp@vger.kernel.org Since DCCP requires to close both ends of a connection simultaneously, permission to write in state DCCP_CLOSING is removed in dccp_sendmsg(): * if the sending end closed, it would encounter a write error anyhow; * if the other end has closed the connection, it accepts no more data.
