From 5dd32bbe8c4cb06df63cadb7e40ecd92997f001d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Zbigniew=20J=C4=99drzejewski-Szmek?= Date: Thu, 18 May 2017 20:58:23 -0400 Subject: [PATCH] sd-login: read list of uids of sessions from UIDS not ACTIVE_SESSIONS As described by Luke Shumaker: sd_seat_get_sessions looks at /run/systemd/seats/${seat_name}:SESSIONS to get the list of sessions (which I believe is correct), and at /run/systemd/seats/${seat_name}:ACTIVE_SESSIONS for the list of users (which I believe is incorrect); I believe that it should look at the UIDS field for the list of users. As far as I can tell, the ACTIVE_SESSIONS field is never even present in the seats file. I also believe that this has been broken since the function was first committed almost 6 years ago. Fixes #5743.
