From 0c7aecd4bde4b7302cd41986d3a29e4f0b0ed218 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Thu, 15 Jan 2015 15:11:15 +0100 Subject: netns: add rtnl cmd to add and get peer netns ids With this patch, a user can define an id for a peer netns by providing a FD or a PID. These ids are local to the netns where it is added (ie valid only into this netns). The main function (ie the one exported to other module), peernet2id(), allows to get the id of a peer netns. If no id has been assigned by the user, this function allocates one. These ids will be used in netlink messages to point to a peer netns, for example in case of a x-netns interface.
