From c422f1bdc3d3f9f637b3d288a6601668e26111d6 Mon Sep 17 00:00:00 2001 From: Allan Stephens Date: Wed, 2 Nov 2011 15:49:40 -0400 Subject: tipc: Simplify enforcement of reserved name type prohibition Streamlines the logic that prevents an application from binding a reserved TIPC name type to a port by moving the check to the code that handles a socket bind() operation. This allows internal TIPC subsystems to bind a reserved name without having to set an atomic flag to gain permission to use such a name. (This simplification is now possible due to the elimination of support for TIPC's native API.)
