Title:
org.freedesktop.DBus.Properties.GetAll fails always for
fi.w1.wpa_supplicant1.Interface interface
Status in wpa package in Ubuntu:
In Progress
Bug description:
With our package for wpa-supplicant a call
$ sudo gdbus call -y -d fi.w1.wpa_supplicant1 -o
/fi/w1/wpa_supplicant1/Interfaces/1 -m
org.freedesktop.DBus.Properties.GetAll
'fi.w1.wpa_supplicant1.Interface'
fails always with
Error: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: No readable
properties in this interface
The reason for this is that the internal properties getter routine
will never return any result when one internal getter fails.
The responsible property here is the "Stations" one which was added by
a patch in Ubuntu and is not available upstream. Take a look at
https://bazaar.launchpad.net/~ubuntu-
branches/ubuntu/wily/wpa/wily/view/head:/debian/patches/dbus-
available-sta.patch
The getter method wpas_dbus_getter_stas expects the ap_iface element
to be see which isn't always the case and if that isn't true it will
return false and causes the whole Properties.GetAll call to fail.
The expected result is that the getter just returns an empty list if
it can't determine the actual value.
