From 7a4e7408c5cadb240e068a662251754a562355e3 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 14 Nov 2011 14:29:51 -0800 Subject: userns: Add kuid_t and kgid_t and associated infrastructure in uidgid.h Start distinguishing between internal kernel uids and gids and values that userspace can use. This is done by introducing two new types: kuid_t and kgid_t. These types and their associated functions are infrastructure are declared in the new header uidgid.h. Ultimately there will be a different implementation of the mapping functions for use with user namespaces. But to keep it simple we introduce the mapping functions first to separate the meat from the mechanical code conversions. Export overflowuid and overflowgid so we can use from_kuid_munged and from_kgid_munged in modular code. Acked-by: Serge Hallyn Signed-off-by: Eric W.
