From e9f238c3041e2582a710e75910c8cbf2a98e51b2 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 11 Aug 2012 12:38:26 -0700 Subject: [PATCH] procfs: Print task uids and gids in the userns that opened the proc file Instead of using current_userns() use the userns of the opener of the file so that if the file is passed between processes the contents of the file do not change.
