** Description changed:
* Impact
extra roaming events are been generated
* Test case
- check the output of `journalctl -lu wpa_supplicant`, it should have warnings
+ check the output of `journalctl -lu wpa_supplicant`, it shouldn't have warnings
dbus: wpa_dbus_property_changed: no property RoamComplete in object /fi/w1/wpa_supplicant1/Interfaces/3
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_property_changed: no property RoamComplete in object /fi/w1/wpa_supplicant1/Interfaces/3
dbus: wpa_dbus_property_changed: no property RoamTime in object /fi/w1/wpa_supplicant1/Interfaces/3
dbus: wpa_dbus_property_changed: no property SessionLength in object /fi/w1/wpa_supplicant1/Interfaces/3
Having done a little research, at least the dbus errors seem to be fixed
by this commit upstream:
https://w1.fi/cgit/hostap/commit/wpa_supplicant/dbus/dbus_new.c?id=23d87687c2428f3b94865580b0d33e05c03e6756
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.)
