[Pkg-utopia-maintainers] Bug#626730: consolekit: Inconsistent behavior between x86-32 and x86-64 regarding login-session-id

[Pascal Dormeau]

Package: consolekit
Version: 0.4.4-1
Severity: minor


Hello,
On two laptops, one with i386 and the other with amd64, with roughly
the same configuration, I can have an active X session with consolekit
working in the amd64 case but not in the i386 case (unless I make use
of pam_loginuid). For amd64, /proc/self/loginuid, /proc/self/sessionid
and ck-lists-session (login-session-id) always return 4294967295 for
login-session-id (for everybody logged in, in a X session or in a
console).
For i386, /proc/self/loginuid, /proc/self/sessionid always return
4294967295 (for everybody logged in, in a X session or in a console),
but ck-lists-session always report empty login-session-id.
I do not know here what should be the correct behavior.
To have an active X session with non empty login-session-id on the
i386, I have to make use of pam_loginuid module
(in /etc/pam.d/common-session). In such case, /proc/self/loginuid
reports correct uid, /proc/self/sessionid and ck-lists-session
(login-session-id) reports the same id, specific to each session (and
different from 4294967295). And finally ck-list-session reports that
the X session is active.
I do not have to do that on amd64.
Additional information in case it matters: on both systems, the X
session can be started by either xdm or startx. libpam-ck-connector is
installed and /etc/X11/Xsession.d/90consolekit is modified such as to
unconditionally run ck-launch-session.

Best regards,
Pascal Dormeau
