Subject: Containers don't handle keys, but should they?
Date: Fri, 14 Mar 2008 11:37:59 +0000 [thread overview]
Message-ID: <7519.1205494679@redhat.com> (raw)
Am I right in thinking that a UID in one container is not necessarily
equivalent to the numerically equivalent UID in another container?
If that's the case then the key management code will need changing as it
assumes all keys belonging to one numeric UID eat out of the same quota and
the numeric UIDs are used in security checks.
Furthermore, processes in one container can access keys created by a process
in another container by ID. Is this desirable or not?
David
