This was initially put in to solve an issue that was specific to
mac80211_hwsim where the connect callback would get queued and
delayed until after the connect event. This caused IWD to get very
confused.
Later it was found that "real" drivers can sometimes do this so
some code was added to IWD core to handle it.
Now there isn't much point to delay all frames unless a rule specifies
so change the behavior back to sending out frames immediately.
The hwsim Rule API was structured as properties so once a rule is
created it automatically starts being applied to frames. This happens
before anything has time to actually define the rule (source, destination
etc). This leads to every single frame being matched to the rule until
these other properties are added, which can result in unexpected behavior.
To fix this an "Enabled" property has been added and the rule will not
be applied until this is true.
The hotspot case can actually result in network being NULL which
ends up crashing when accessing "->secrets". In addition any
secrets on this network were never removed for hotspot networks
since everything happened in network_unset_hotspot.
testHotspot suffered from improper cleanup and if a single test failed
all subsequent tests would fail due to IWD still running since IWD()
was never cleaned up.
In addition the PSK agent and hwsim rules are now set onto the cls
object and removed in tearDownClass()
There are really no cases where a test wants to remove a single
rule. Most loop through and remove rules individually so this
is being added as a convenience.
Certain autotests coupled with slower test machines can result in lost
beacons and "Network not found" errors. In attempt to help with this
the test can just rescan (30 seconds max) until the network is found.
Remove EAP-SIM from the generic PEAP test case since skipping
(if ofono is not on system) would skip the entire test rather
than just the EAP-SIM portion.
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()).
