This tests all EAP methods in their standard configuration. Any
corner cases requiring changes to main.conf or other hostapd
options are not included and will be left as stand alone tests.
This was done because nearly all EAP tests are identical except
the IWD provisioning file and hostapd EAP users fine. The IWD
provisioning file can be swapped out as needed for each individual
test without actually restarting IWD. And the EAP users file can
simply be written to include every possible EAP method that
is supported.
The -S/--sub-tests option allows the user to specify a test file
from inside an autotest. Inside this file there may also be many
test functions. This option is being extended to allow running
a single test function inside a test file. For example:
* Runs all test functions inside connection_test.py *
./test-runner -A some_test -S connection_test
* Runs only connection_test.py test_connect_success() *
./test-runner -A some_test -S connection_test.test_connect_success
The destructor was trying to do more than the scope of a destructor
by trying to handle this single case of hostapd being restarted.
Instead we can simply pass a keyword argument 'reinit' to the
constructor to tell it to reinitialize everything. And as for killing
hostapd this can be done in ungraceful_restart itself rather than
trying to handle it in the destructor.
There was a race condition here where the GLib timeout could have
fired but the test function returned successfully prior to the
end of the while loop. This would end up causing source_remove to
print a warning that the source did not exist.
Instead check if the timeout fired prior to removing it.
This (hopefully) will make this test pass better on slower machines.
In addition the mechanism of copying over separate main.conf files
was changed (rather than echo'ing the option into /tmp/main.conf)
This addresses the TODO where HostapdCLI was creating separate
objects each time HostapdCLI was called. This was worked around
by manually setting the important members but instead the class
can be re-worked to act as somewhat of a singleton, per-config
at least.
If there is no HostapdCLI instance for a given config one is
created and initialized. Subsequent HostapdCLI calls (for the
same config) will be returned the same object rather than a
new one.
Tests that called skipTest would result in an exception which would
hault execution as it was uncaught. In addition this wouldn't result
in an skipped test.
Now the actual test run is surrounded in a try/except block, skipped
exceptions are handled specifically, and a stack trace is printed if
some other exception occurs.
dmesg was being called at the very end of testing and dumped into
a log file. If many tests were run this could take quite a long
time and was timing out the default process wait. Instead --follow
can be used (basically like 'tail') which prints messages as they
come and avoids the time consuming full dump at the end.
The hotspot ANQP delay test was setting a global delay on all
packets which had some unintended consequences. At the time this
was the only way of simulating the test scenario but now hwsim
supports prefix matching so only the ANQP request/response will
be delayed.
This test was accessing the subprocess object and calling terminate
which ends up causing issues with test-runners own process cleanup.
Instead kill() should be used.
Hostapd sometimes has trouble with specifying additional BSSs in
a single config file, at least in the test-runner environment.
Since all the BSS's specified were identical instead the test was
reworked to only have a single BSS and each subtest can connect
in its own unique way.
This test took quite a while to execute (~2 minutes on my machine)
because there was simply no other way to test this scenario but
waiting. Now the no-roam-candidates condition can be waited for
rather than just sleeping for 20 seconds. Additionally the default
RoamRetryInterval was being used which is 60 seconds. Instead
main.conf can set this to 5 seconds and really cut down on the time
to wait.
Part of a comment was also removed due to being incorrect. Even
with neighbor reports IWD still must scan, its just that the
scan is more limited and, in theory, faster.
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.
