Package: dbus
Version: 1.12.16-1
Severity: normal
Dear Maintainer.
As subject says, if sssd can't reach dc, dbus get NoReply fail and succesfully
restarted aftervards with following consequences:
1. reload process lagging due sssd timeouts;
2. other daemons fail because 1 or dbus restart;
3. failed reload at packet install process may lead to overall install fail;
Because of automatic config reload, 1 is strikes at periodic manner.
The most notorious example of 2 is NetworkManager, which gets SIGTERM
(org.freedesktop.nm_dispatcher timeout), shutdown network and require manual
restart, despite the fact that dbus already restarted. Nice to have bunch of
isolated instances at midnight because of network spike (:
3 is theoretical and depends on packages postinstall scripts and hooks.
Steps to reproduce:
1a. Get minimal setup with some additional packages:
# debootstrap --arch=amd64
--include=network-manager,sssd,iio-sensor-proxy,ovirt-guest-agent,linux-image-amd64,grub-pc
stable /mnt
# #Do other stuff to boot from...
1b. Or add network-manager, sssd, iio-sensor-proxy and ovirt-guest-agent to
fresh setup. Last two will add policy with currently nonexistent users gdm and
geoclue. Skip sssd realm config. You may notice NoReply fail due setup.
2. Check NetworkManager status and restart if already dead.
3. Do systemctl reload dbus.service. Notice time taken.
4. Check NetworkManager again. Status change to 'dead' after step 3 or some
short time.
5. Check dbus journal. Notice org.freedesktop.nm_dispatcher activation fail,
NoReply and restart.
BONUS STAGE: remove one user policy (eg. purge ovirt-guest-agent OR
iio-sensor-proxy), restart NetworkManager and do dbus reload again. This time
NM not fail.
