With the addition of connect_bssid/roam very few tests actually
require hwsim. Since hwsim can lead to problems with scan results
its best to have it off by default and have each test that needs
it explicitly turn it on.
Tests which previously turned it off have had that option removed.
Tests that do require hwsim still are vulnerable to scan result
problems, so for these tests beacon_int was added to the hostapd
config which seems to help with reliability somewhat.
After the test-runner re-write many tests were left with
stale options that are no longer used at all. These were
periodically getting removed as changes were made to
individual tests, but its apparent now that a tree wide
removal was needed.
Running autotests with native hardware will not work on tests which
depend on the hwsim python API (since hwsim will not be running).
For these tests, it will now be required that they specify:
needs_hwsim=1
This allows the test to be skipped when running with native hardware
rather than the test failing with a python exception.
Two autotests:
1. Tests SA Query procedure when the AP goes down. In this case the AP
goes down ungracefully, now allowing it to send out any deauth
frames. When the AP comes back up, IWD still thinks its connected.
The AP will then send unprotected disassociate frames so the client
can re-connect. This kicks off the SA Query procedure, which the AP
will not respond to. At this point we can deauth and reconnect to
the AP.
2. Test SA Query procedure when a disassociate frame has been spoofed.
In this case we receive an unprotected disassociate frame and start
SA Query. The AP should then respond to the SA query within the
timeout. We then know the frame was spoofed and can remain
connected.
