From a2cfd45b52006893fc0d0e850d187d30f86a39dc Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Thu, 26 Apr 2012 16:46:29 -0400 Subject: tipc: Optimize re-initialization of configuration service Streamlines the job of re-initializing TIPC's configuration service when a node's network address is first assigned. Rather than destroying the configuration server port and then recreating it, TIPC now simply withdraws the existing {0,<0.0.0>} name publication and creates a new {0,} name publication that identifies the node's network address to interested subscribers.
