Subject: [PATCH 1/2] [DCCP]: Reduce the number of writable states
Date: Wed, 26 Sep 2007 23:07:43 +0000 [thread overview]
Message-ID: <20070926230743.GP10932@ghostprotocols.net> (raw)
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.
