From d67c0bf0caf26358f5345d6c0ac039026c46bd1e Mon Sep 17 00:00:00 2001
From: Aleksa Sarai <asarai@suse.de>
Date: Fri, 22 Apr 2016 20:36:43 +1000
Subject: [PATCH] libcontainer: user: always treat numeric ids numerically
Most shadow-related tools don't treat numeric ids as potential
usernames, so change our behaviour to match that. Previously, using an
explicit specification like 111:222 could result in the UID and GID not
being 111 and 222 respectively (which is confusing).
Some of the code was quite confusing inside libcontainer/user, so
refactor and comment it so future maintainers can understand what's
going and what edge cases we have to deal with.
This fixes CVE-2016-3697.
