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.
Since IWD tries group 20 first all other OWE tests are actually
triggering group negotiation where this test is not. Since this
code is exercised this test can be removed completely, as well
as the additional radio/network.
This test simulates the scenario where IWDs commit is not acked which
exposes a hostapd bug that ultimately fails the connection. This behavior
can be seen by reverting the commit which works around this issue:
"sae: don't send commit in confirmed state"
With the above patch applied this test should pass.
Note: The existing timeout test was reused as it was not of much use
anyways. All it did was block auth/assoc frames and expect a failure
which didn't exercise any SAE logic anyways.
This was a placeholder at one point but modules grew to depend on it
being a string. Fix these dependencies and set the root namespace
name to None so there is no more special case needed to handle both
a named namespace and the original 'root' namespace.
With various versions of wpa_supplicant tested, after an IWD GO tears
the group down, the wpa_supplicant P2P client will not immediately
signal that the group has disappeared but will at least wait for the
lost beacon signal, wait some more and try reconnecting and all that
takes it 10s or a little longer. Possibly sending Deauthenticate frames
to clients first would improve this.
mac80211_hwsim has a funny quirk with multiple addresses in
radios. Some operations require address index zero, some index
one. And these addresses (possibly a result of how test-runner
initializes radios) sometimes get mixed up. For example scan
results may show a BSS address as 02:00:00:00:00:00, while the
next test run shows 42:00:00:00:00:00.
Ultimately, sending out frames requires the first nibble of the
address to be 0x4 so to handle both variants of addresses described
above hwsim.py was updated to always bitwise OR the first byte
with 0x40.
The idea of this test is valid but it is extremely timing dependent
which simply isn't testable on all machines. Removing this test
at least until this can be tested reliably.
