Bug Description
* Impact
extra roaming events are been generated
* Test case
check the output of `journalctl -lu wpa_supplicant`, it shouldn't have those warnings
dbus: wpa_dbus_
the roaming events should not be too frequent
* Regression potential
check that wifi connection keep working correctly
--------------
When using this version of wpa_supplicant with my company WPA2-Enterprise wireless setup, I'm experiencing far too frequent roaming events (even when not moving around) accompanied by hiccups in connectivity. I also see these messages in the wpa_supplicant log:
dbus: wpa_dbus_
dbus: wpa_dbus_
dbus: wpa_dbus_
Having done a little research, at least the dbus errors seem to be fixed by this commit upstream:
So I built a version of wpa_supplicant including this particular patch and installed on my machine. Apart from solving the dbus errors completely, it seems to have had a positive impact on the frequent roaming and unstable connectivity as well (I've run for a day with no burst of roaming events at all, where they used to happen every few minutes most of the time.)
