This changes all tests to use the default get_ordered_network behavior
rather than some custom or incorrect logic. Any use of
scan_if_needed=True has been removed since this is now the default.
Also any explicit scanning has been removed for tests which do not
require it (where the default behavior is good enough).
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.
[General].APRange is now [IPv4].APAddressPool and the netmask is changed
from 23 to 27 bits to make the test correctly assert that only two
default-sized subnets are allowed by IWD simultaneously (default has
changed from 24 to 28 bits)
The existing AP tests needed to be modified to start IWD from
python since the DHCP test uses a different main.conf.
Also removed some stale hw.conf options that are no longer used.
Many tests waited on the network object 'connected' property after
issuing a Connect command. This is not correct as 'connected' is
set quite early in the connection process. The correct way of doing
this is waiting for the device state to change to connected.
This common code was replaced, hopefully putting to rest any random
failures that happen occasionally.
As with other tests, wait on device state instead of the network
object. The connectivity test was also changed to not check for
group traffic since AP does not negotiate the IGTK at this time.
The tests basically remained the same with a few minor changes.
The wiphy_map and in turn hostapd_map are no longer used. This
was already partially converted a long time ago when the 'config'
parameter was added to HostapdCLI. This patch fully converts all
autotests to use 'config' rather than looking up by interface.
Some test scripts were named 'test.py' which was fine before but
the new rewrite actually loads each python test as a module. The
name 'test' is too ambiguous and causes issues due to a native
python module with the same name. All of these files were
renamed to 'connection_test.py'.
Fixed two issues:
1. There is no longer a dbus exception when switching to AP mode when
connected in station mode so that assert was removed.
2. After the device/station change the timing must have changed, causing
autoconnect to take over before an explicit connect call. Added a
psk provisioning file that disables autoconnect.
Make sure stop_ap is called on success and on failure in both tests so
that one can succeed after the other has failed. Also make sure to move
both interfaces out of autoconnect state.
list_devices() was updated to take an integer rather than a bool
for the wait_to_appear argument. This updates any tests that
explicily passed True/False as the argument to list_devices.
The single AP test worked fine, but adding a failure test caused some
problems. Since the kernel is never restarted between tests it maintains
old stale scan results from the previous test. This was causing an
assert to sometimes fail in the second test being run because it was
returning > 1 ordered networks. This change iterates through the ordered
network list and chooses the appropriate network rather than assuming
get_ordered_networks() will always return only one network object
