From 4ac1c8d0ee9faf3a4be185cc4db1381fa0d81280 Mon Sep 17 00:00:00 2001 From: Ying Xue Date: Fri, 9 Jan 2015 15:27:09 +0800 Subject: tipc: name tipc name table support net namespace TIPC name table is used to store the mapping relationship between TIPC service name and socket port ID. When tipc supports namespace, it allows users to publish service names only owned by a certain namespace. Therefore, every namespace must have its private name table to prevent service names published to one namespace from being contaminated by other service names in another namespace. Therefore, The name table global variable (ie, nametbl) and its lock must be moved to tipc_net structure, and a parameter of namespace must be added for necessary functions so that they can obtain name table variable defined in tipc_net structure.
