Bug description:
After a suspend/resume, network-manager claimed that wireless was not
available and would not let me reconnect to the wireless here.
'iwlist wlan1 scan' would also not work; so thinking that it was a
driver problem, I rebooted the system. When it came back up, nm-
applet in lightdm claimed that networking was disabled, and the option
to enable it was greyed out. It could also not be enabled by nmcli.
I ended up stopping network-manager, bringing up the interface via
/etc/network/interfaces, and logging in... at which point, restarting
network-manager *did* let me enable networking from my logged-in
session.
So there are several problems here:
- after a reboot, network-manager claimed networking was disabled.
- nm-applet is not letting me enable networking from the lightdm session.
- the networking was failing after a suspend/resume cycle, and could not be
enabled even from inside the user session.
The last issue probably *was* a kernel driver problem; but the first
two issues are network-manager problems of some kind.
SRU INFORMATION:
----------------
Reproducer:
- Force suspend to take very long by adding a sleep:
echo -e '#!/bin/sh\nsleep 15\nexit 1' | sudo tee
/usr/lib/pm-utils/sleep.d/00break
(this will also make suspend fail, which eases testing)
- Suspend from the menu or with
sudo gdbus call -y -d org.freedesktop.login1 -o /org/freedesktop/login1 -m
org.freedesktop.login1.Manager.Suspend true
- With the 13.10 final version, systemd-shim will (often) time out, and the
next Suspend call from above will fail with "Operation already in progress" and
the network does not come back up. With the fixed version, network should be
back up and the Suspend() call can be issued many times.
Fix:
https://github.com/desrt/systemd-shim/commit/136ed1143077d13c2
https://github.com/desrt/systemd-shim/commit/16a7fdc0652ad78f4
Regression potential: Errors in this code could potentially break
suspend/shutdown completely, so for verification both of these
functionalities ought to be tested on real hardware.
