From 87227fe7e42060af9bc8977fc17427e7c9cadb5d Mon Sep 17 00:00:00 2001 From: Parthasarathy Bhuvaragan Date: Tue, 1 Nov 2016 14:02:39 +0100 Subject: tipc: remove tsk->connected for connectionless sockets Until now, for connectionless sockets the peer information during connect is stored in tsk->peer and a connection state is set in tsk->connected. This is redundant. In this commit, for connectionless sockets we update: - __tipc_sendmsg(), when the destination is NULL the peer existence is determined by tsk->peer.family, instead of tsk->connected. - tipc_connect(), remove set/unset of tsk->connected. Hence tsk->connected is no longer used for connectionless sockets. There is no functional change in this commit.
