Controlling wpa_supplicant/hostapd from a text based interface is
problematic in that there is no way of knowing if an event corresponds
to a request. In certain cases if wpa_s/hostapd is sending out multiple
events and we make a request, a random event may come back after the
request, but before the actual result.
To fix this, at least for this specific case, we can continue to read
from the socket until the result is numeric.
Some wpa_cli utilities return some result which isn't possible to
get with wait_for_event unless you know what the result will be.
This adds wait_for_result which just returns the first event that
comes in.
wait_for_event was checking the event string presence in the rx_data
array which meant the event string had to match perfectly to any
received events. This poses problems with events that include additional
information which the caller may not be able to know or does not care
about. For example:
DPP-RX src=02:00:00:00:02:00 freq=2437 type=11
Waiting for this event previously would require the caller know src, freq,
and type. If the caller only wants to wait for DPP-RX, it can now do that.
Since a Device class can represent multiple modes (AP, AdHoc, station)
move StationDebug out of the init and only create this class when it
is used (presumably only when the device is in station mode).
The StationDebug class is now created in a property method consistent
with 'station_if'. If Device is not in station mode it is automatically
switched if the test tries any StationDebug methods.
If the Device mode is changed from 'station' the StationDebug class
instance is destroyed.
Passing the full argument list to StationDebug was removed
because any existing properties (for Device) were being
included and causing incorrect behavior.
This neglected to handle namespaces which should also be
passed to StationDebug. Unfortunately the arguments are not
named when Device() is initialized so they cannot easily be
sorted. Instead just define Device() arguments to match the
DBus abstraction and pass only the path and namespace to
StationDebug
Make sure we wipe the leases file both for server and client, so that
dhclient doesn't try to re-use leases from previous tests (should really
happen) and waste time waiting for a reply. Extend the timeout from 1s
to 5s, sometimes it takes dhclient 1s just to start. Disable verbose
mode if not needed to avoid dhclient stalling if the pipe is not being
read.
Passing *args, **kwargs into StationDebug ended up initializing the
class with Station properties since devices can be initialized from
existing property dictionaries. Since the object path is all
StationDebug needs, pass args[0] instead.
On some systems the default radvd pid file location is not accessible.
Specify it to be under /tmp instead.
While there, enable full radvd debug output so it is logged when
test-runner is invoked with the --log option.

If a beacon is lost testAP will fail since it did not utilize any
rescanning logic. Now it can use this feature by passing full_scan.
This is required since IWD APs are not known to test-runner like
hostapd APs are.
Certain scenarios coupled with lost beacons could result in OrderedNetwork
being initialized many times until the dbus library reached its maximum
signal registrations. This could happen where there are two networks,
IWD finds one in a scan but continues to scan for the other and the beacons
are lost. The way get_ordered_networks was written it returns early if any
networks are found. Since get_ordered_network (not plural) uses
get_ordered_networks() in a loop this caused OrderedNetwork's to be created
rapidly until python raises an exception.
To fix this, pass an optional list of networks being looked for to
get_ordered_networks. Only if all the networks in the list are found will
it return early, otherwise it will continue to scan.
There was no open ssid provisioning file, which was fine as the
first test should have created one. But to be safe, include one
explicitly and use the proper setUp/tearDown functions.
By sleeping for 4 seconds IWD had plenty of time to fully disconnect
and reconnect in time to pass the final "connected" check. Instead
use wait_for_object_condition to wait for disconnected and expect
this to fail. This will let the test fail if IWD disconnects.
REKEY_GTK kicks off the GTK only handshake where REKEY_PTK does
both (via the 4-way). The way this utility was written was causing
hostapd some major issues since both REKEY_GTK and REKEY_PTK was
used.
Instead if address is set only do REKEY_PTK. This will also rekey
the GTK via the 4-way handshake.
If no address is set do REKEY_GTK which will only rekey the GTK.
The FT-over-DS test was allowed to fail as it stood. If FT-over-DS
failed it would just do a normal over-Air transition which satisfied
all the checks. To prevent this Authenticate frames are blocked after
the initial connection so if FT-over-DS fails there is no other way
to roam.
This adds several tests for OWE transition networks. Hostapd
does have special options for these networks but currently their
implementation is incorrect as the IE is not ever added to the
OWE BSS. Besides that using vendor_elements provides a much easier
way to create invalid IEs to test.
