[pkg-wpa-devel] Bug#798128: wpasupplicant needs restarting after suspend

[Ian Jackson]

Package: wpasupplicant
Version: 2.3-1+deb8u1
Severity: normal
Control: fixed -1 1.0-3+deb7u2

Since I upgraded my netbook to jessie, the wifi does not work after
suspend.

Testing different versions of relevant software reveals that:
 * vanilla jessie does not work
 * reverting kernel or firmware-iwlwifi to wheezy makes no difference
 * reverting wpasupplicant to the .deb from wheezy (1.0-3+deb7u2)
   fixes the problem

When it's in the broken state, I get messages like those you see
below, in daemon.log.  I can work around the bug (until the next
suspend) with `killall wpa_supplicant'.  Network-Manager then restarts
wpa_supplicant and the restarted instance works.

In case it's relevant: the machine is a Dell Latitude 2120, with an
Intel `Advanced-N 6235' (according to lspci).  The access point is a
TP-Link; but I have seen the same symptoms at work using the corporate
wifi (not sure what the AP is there).
