When (for example) switching from X11 to a new VT and logging in there,
|
|
|
1ff636 |
creating a new session, the user state file (/run/systemd/users/$uid) is
|
|
|
1ff636 |
not updated after the session becomes active. The latest time it is
|
|
|
1ff636 |
saved is when the session is in SESSION_OPENING.
|
|
|
1ff636 |
|
|
|
1ff636 |
This results in a /run/systemd/users/$uid file which contains
|
|
|
1ff636 |
STATE=online for the current user on the current active VT, which is
|
|
|
1ff636 |
obviously wrong.
|
|
|
1ff636 |
|
|
|
1ff636 |
As functions like sd_uid_get_state() use this file to get the user’s
|
|
|
1ff636 |
state, this could result in things like PolicyKit making incorrect
|
|
|
1ff636 |
decisions about the user’s state. (See
|
|
|
1ff636 |
https://bugs.freedesktop.org/show_bug.cgi?id=76358.)
|
|
|
1ff636 |
|
|
|
1ff636 |
Fix this by re-saving the state for a session’s user after completing
|
|
|
1ff636 |
the state_job for that session.
