This is meant to be used as a generic notification to autotests. For
now 'no-roam-candidates' is the only event being sent. The idea
is to extend these events to signal conditions that are otherwise
undiscoverable in autotesting.
There was a common bit of code all over test-runner and utilities
which would wait for 'something' in a loop. At best these loops
would do the right thing and use the GLib.iteration call as to not
block the main loop, and at worst would not use it and just busy
wait.
Namespace.non_block_wait unifies all these into a single API to
a) do the wait correctly and b) prevent duplicate code.
Replace instances of the ap_del_station() +
ap_sta_free()/ap_remove_sta() with calls to ap_station_disconnect to
make sure we consistently remove the station from the ap->sta_states
queue before using ap_del_station(). ap_del_station() may generate an
event to the ap.h API user (e.g. P2P) and this may end up tearing down
the AP completely.
For that scenario we also don't want ap_sta_free() to access sta->ap so
we make sure ap_del_station() performs these cleanup steps so that
ap_sta_free() has nothing to do that accesses sta->ap.
client_frame is not valid for a beacon frame as beacons are not sent in
response to another frame. Move the access to client_frame->address_2
to the conditional blocks for Probe Response and Association Response
frames.
get_ordered_network() now scans automatically and has been updated
to use the StationDebug.Scan() API rather than doing a full
dbus scan (unless full_scan = True). The frequencies to be scanned
are picked automatically based on the current hostapd status
(hidden behind ctx.hostapd.get_frequency()).
This is to support the autotesting framework by allowing a smaller
scan subset. This will cut down on the amount of time spent scanning
via normal DBus scans (where the entire spectrum is scanned).
While losing the convenience of unittest this patch breaks out
each individual test function in order to run it manually and
get results. This vastly improves the user experience by seeing
which test file and function is being executed rather than simply
seeing "PASSED" for the entire test set.
In addition exceptions/failures are printed out as they happen
rather than at the end.
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.
There is a common block of code in nearly every test which is incorrect,
most likely a copy-paste from long ago. It goes something like:
wd.wait_for_object_condition(device, 'not obj.scanning')
device.scan()
wd.wait_for_object_condition(device, 'not obj.scanning')
network = device.get_ordered_network("ssid")
The problem here is that sometimes the scanning property does not get
updated fast enough before device.scan() returns, meaning get_ordered_network
comes up with nothing. Some tests pass scan_if_needed=True which 'fixes'
this but ends up re-scanning after the original scan finishes.
To put this to rest scan_if_needed is now defaulted to True, and no
explicit scan should be needed.
Most autotests do not want autoconnect behavior so it is being
turned off by default. There are a few tests where it is needed
and in these few cases the test can enable autoconnect through
the new station debug property.
This adds the property "AutoConnect" to the station debug interface
which can be read/written to disable or enable autoconnect globally.
As one would expect this property is only going to be used for testing
hence why it was put on the debug interface. Mosts tests disable
autoconnect (or they should) because it leads to unexpected connections.
In addition the send_bss_transition call was updated to only send a
single BSS. By sending two BSS's IWD is left to pick whichever one
it wants which makes the test behavior undefined.
This will use the Roam() developer method to force a roam to
a certain BSS. This is particularly useful for any test requiring
roams that are not testing IWD's BSS selection logic. Rather than
creating hwsim rules, setting low RSSI values, and waiting for the
roam logic/scan to happen Roam() can be used to force the roam
logic immediately.
Several tests tests for connectivity with the expectation that it
will fail. This ends up taking 30+ seconds because testutil retries
3 times, each with a 10 second timeout. By passing expect_fail=True
this lowers the timeout to zero, and skips any retries.
If a test has no hw.conf file test-runner was fully exiting and not
running any additional tests. This shouldn't happen in practice
since all upstreamed tests should run, but if any locally created
tests existed like this, it would cause the entire test run to exit
early.
Instead raise an exception which bails out of only that test, and
allows the rest to continue.
This method will initiate a connection to a specific BSS rather
than relying on a network based connection (which the user has
no control over which specific BSS is selected).
The only point of failure in netdev_connect_common was setting
up the handshake type. Moving this outside of netdev_connect_common
makes the code flow much better in netdev_{connect,reassociate} as
nothing needs to be reset upon failure.
