Sometimes scan results can come in with a MAC address which
should be in the first index of addrs[] (42:xx:xx:xx:xx:xx).
This causes a failure to lookup the radio path.
There was also a failure path added if the radio cannot be
found rather than rely on DBus to fail with a None path.
The arguments to SendFrame were also changed to use the
ByteArray DBus type rather than python's internal bytearray.
This shouldn't have any effect, but its more consistent with
how DBus arguments should be used.
This got added in the re-write but a __del__ method was also
added to the Rule class as well. This caused problems if hwsim
cleaned up since it removed the rules, which caused each rule
to call __del__. Since the rule had already been removed there
was no longer a DBus interface which raised an exception.
It is not safe to assume that the python dbus implementation will
wait for a method to return. The documentation says this with
respect to reply_handler/error_handler:
"If both are None, the implementation may request that no reply is sent"
To stay on the safe side we should always include the error/reply
handlers and wait for the operation to complete.
At some point a stray ';' got added into an autotest in a section
of code that is heavily copy pasted. So in turn nearly all the autotests
have this stray ';' after list_devices (and a few in other places).
Changed disassociate reason to 0x07 when spoofing a disassociate
frame. This along with 0x06 are the only two reason codes that
should be accepted in an unprotected disassociate frame.
Using the hwsim dbus interface ".Interface" under the radios
object you can now send an arbitrary frame out from that radio.
Two methods have been added, spoof_frame and spoof_disassociate.
In the beacon loss test try to simulate a periodic communication problem
because we don't support roaming if the AP goes away completely.
2 seconds seems to be enough to consistently trigger the beacon_loss
event without triggering a disconnect by the linux kernel or hiding the AP
from the roam scan. Also set the RSSI for that AP lower so that it is
not reselected by iwd.
