[pkg-wpa-devel] Bug#753345: wpasupplicant hook for pm-utils breaks pm-suspend when used with wicd

[fzacarias3k at gmail.com]

Package: wpasupplicant
Version: 1.1-1
Severity: important

Dear Maintainer,

After installing wicd and wpasupplicant, suspending the computer
with pm-suspend stops working.
The problem lies in the wicd and wpasupplicant installed hooks for
pm-utils colliding.
wicd's hook runs first and disconnects my wireless device, causing
wpa_supplicant process to stop. Then the wpasupplicant's hook runs and
tries to execute the suspend command but the hook fails because wpa_cli
can't find the control socket (because it was removed by the previous
hook!).
Extract from /var/log/pm-suspend.log:
---
Running hook /usr/lib/pm-utils/sleep.d/60_wpa_supplicant suspend
suspend:
Failed to connect to wpa_supplicant - wpa_ctrl_open: No such file or
directory
/usr/lib/pm-utils/sleep.d/60_wpa_supplicant suspend suspend: Returned
exit code 255.

Mon Jun 30 20:03:15 CEST 2014: Inhibit found, will not perform suspend
Mon Jun 30 20:03:15 CEST 2014: Running hooks for resume
---

This can be reproduced every time. I temporarily fixed it by appending
"exit 0" to wpasupplicant's hook.
Better solutions might be:
  * run this hook before wicd's
  * verify wpa_supplicant's control socket existance
