[Bug 1400203] Re: libsystemd-login sd_login_monitor_new not working
Apologies for the delay, I updated the bug description with a
justification for SRU; let me know if there's anything else I can do to
help.
** Description changed:
- There is a C API in libsystemd-login for receiving notifications, see
- sd_login_monitor_new(3). It is not working in the Utopic version of
- systemd, because it attempts to access /run/systemd/machines which does
- not exist on utopic.
+ [Impact]
+ The systemd login monitoring library (API: sd_login_monitor_new(3)) is not
+ functional in Utopic. This library is a dependency in NetworkManager, for
+ tracking user sessions. As a result, my laptop does not reconnect to
+ the network after a suspend/resume cycle.
- I see a patch to fix this in the older, Trusty Tahr version of systemd
- (http://bazaar.launchpad.net/~ubuntu-
- branches/ubuntu/trusty/systemd/trusty/view/head:/debian/patches/login-
- monitor-no-machine.patch). The patch isn't in the utopic systemd
- (208-8ubuntu8).
+ There was a patch to fix this in the older, Trusty Tahr version of systemd
+ (http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/trusty/systemd/trusty/view/head:/debian/patches/login-monitor-no-machine.patch).
+ The patch isn't in the utopic systemd (208-8ubuntu8).
- I tracked down an issue in NetworkManager which I believe was due to
- this issue. Attached is a C program to demonstrate.
+ This was discovered in a Gnome Fallback session, but I think this KDE issue
+ may be the same thing: https://bugs.kde.org/show_bug.cgi?id=340568
+ Note: This behavior is only seen when "All users may connect to this
+ network" is un-selected in NetworkManager.
+ NOTE: in order to get a fully working network, I also had to make a
+ change to the upstart script, see:
+ https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1400205
+
+ [Test Case]
+ A short C program to demonstrate sd_login_monitor_new is attached to the
+ bug, to demonstrate whether sd_login_monitor_new() is working.
+
+ To do an end-to-end test, you can stop NetworkManager, re-run it with
+ "NetworkManager --no-daemon", and look for the "Error getting login
+ monitor:" error message.
+
+ [Regression Potential]
+ Fixing this simply means applying a patch which shipped along with
+ Trusty Tahr's systemd. Since it was widely used already, adding it to
+ Utopic does not appear overly risky.
