[Bug 1473800] Re: restarting logind during systemd update causes screen to lock

[Seth Arnold]

Worked for me on trusty.

I had trouble with sudo apt-get install systemd-services/trusty-proposed
-- it wanted to uninstall too many things. Probably it would have worked
fine with sudo apt-get install systemd-services/trusty-proposed libpamd-
systemd/trusty-proposed. Oops.

I instead asked apt to upgrade all the binary packages built from the systemd 
source package:
sudo apt-get install -t trusty-proposed gir1.2-gudev-1.0 libgudev-1.0-0 
libpam-systemd libsystemd-daemon0 libsystemd-journal0 libsystemd-login0 
libudev1 libudev1 systemd-services udev

This restarted systemd-logind as expected (and blanked my screen
momentarily).

I asked apt to re-install all those packages:
sudo apt-get install -t trusty-proposed --reinstall gir1.2-gudev-1.0 
libgudev-1.0-0 libpam-systemd libsystemd-daemon0 libsystemd-journal0 
libsystemd-login0 libudev1 libudev1 systemd-services udev

This time systemd-logind did not restart and my screen did not blank.

Thanks Martin!

[Brian Murray]

Hello Michael, or anyone else affected,

Accepted systemd into trusty-proposed. The package will build now and be
available at
https://launchpad.net/ubuntu/+source/systemd/204-5ubuntu20.19 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

[Bug 1473800] Re: restarting logind during systemd update causes screen to lock

[Martin Pitt]

** Description changed:

  When systemd is updated (through the update manager), the screen/session
  locks when processing the update.
  
  I've had this happen twice I think, and the only suspicious packages are
  the systemd ones.
+ 
+ 
+ SRU INFORMATION:
+ 
+ - Fix from wily/xenial: 
http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/diff/?id=b8c239 ; This 
follows other distributions like Fedora which never restarted logind on package 
upgrades. This just causes too much fallout from clients which listen to the 
D-Bus address and get confused when logind goes away and comes back.
+ - Regression potential: This is harmless as long as we don't push an urgent 
fix to logind itself as an SRU. In this case we might need to re-add the 
restart on upgrade (with a version guard). This is unlikely/seldom, though. For 
this particular upgrade there is no regression potential as there are no logind 
changes (for the record, we've never had a logind SRU so far).
+ - Test case:
+   * Check "pidof systemd-logind"
+   * Upgrade "systemd-services" and "libpam-systemd" to the -proposed version
+   * The above upgrade will restart logind (as we can't retroactively fix the 
prerm of the old package) and "pidof systemd-logind" should now show a 
different pid.
+   * sudo apt-get install --reinstall libpam-systemd → now "pidof 
systemd-logind" should be identical to the previous one, i. e. from now on 
upgrades of libpam-systemd do not restart logind any more.
+

This bug was fixed in the package systemd - 225-1ubuntu7

systemd (225-1ubuntu7) wily; urgency=medium

  * Don't restart logind on upgrades any more. This kills X.org (#798097)
while logind doesn't save/restore its open fds (issue #1163), and also
gets confused about being idle in between (LP: #1473800)
  * debian/extra/initramfs-tools/hooks/udev: Copy all
/etc/udev/rules.d/*.rules rules which are not merely overriding the one in
/lib/, not just 70-persistent-net.rules.  They might contain network names
or other bits which are relevant for the initramfs. (Closes: #795494)
  * ifup@.service: Drop PartOf=network.target; we don't want to stop these
units during shutdown. Stopping networking.service already shuts down the
interfaces, but contains the safeguard for NFS or other network file
systems. Isolating emergency.target still keeps working as before as well,
as this also stops networking.service. (Closes: #761909, LP: #1492546)
  * networkd: Change IPForward= default to "kernel". This keeps compatibility
with lots of packages which expect to be able to enable global forwarding
in /proc/sys/net/ipv4/ip_forward. (LP: #1500992)

what we do right now in the systemd package (so that after a dist-
upgrade you actually run the current version).

[Bug 1473800] Re: restarting logind during systemd update causes screen to lock

[Martin Pitt]

When doing systemctl daemon-reexec; [optional sleep]; systemctl try-
restart systemd-logind, loginctl show-session reveals that the current
session gets IdleHint=yes for a second or two, which causes the screen
lock. This does not seem to happen when *only* restarting logind without
a previous daemon-reexec.
