From 74503494469a3f22eb77277a7a8cd1931a70fc24 Mon Sep 17 00:00:00 2001 From: Andrey Vagin Date: Fri, 31 Oct 2014 12:14:20 +0300 Subject: [PATCH] userns: define protobuf messages for uid and gid maps Normally, one of the first steps after creating a new user namespace is to define the mappings used for the user and group IDs of the processes that will be created in that namespace. This is done by writing mapping information to the /proc/PID/uid_map and /proc/PID/gid_map files corresponding to one of the processes in the user namespace.
