From 2ea190d0a006ce5218baa6e798512652446a605a Mon Sep 17 00:00:00 2001 From: "Serge E. Hallyn" Date: Thu, 26 Feb 2009 18:27:55 -0600 Subject: keys: skip keys from another user namespace When listing keys, do not return keys belonging to the same uid in another user namespace. Otherwise uid 500 in another user namespace will return keyrings called uid.500 for another user namespace. Signed-off-by: Serge E.
