This adds several tests for OWE transition networks. Hostapd
does have special options for these networks but currently their
implementation is incorrect as the IE is not ever added to the
OWE BSS. Besides that using vendor_elements provides a much easier
way to create invalid IEs to test.
Since IWD tries group 20 first all other OWE tests are actually
triggering group negotiation where this test is not. Since this
code is exercised this test can be removed completely, as well
as the additional radio/network.
This test simulates the scenario where IWDs commit is not acked which
exposes a hostapd bug that ultimately fails the connection. This behavior
can be seen by reverting the commit which works around this issue:
"sae: don't send commit in confirmed state"
With the above patch applied this test should pass.
Note: The existing timeout test was reused as it was not of much use
anyways. All it did was block auth/assoc frames and expect a failure
which didn't exercise any SAE logic anyways.
This was a placeholder at one point but modules grew to depend on it
being a string. Fix these dependencies and set the root namespace
name to None so there is no more special case needed to handle both
a named namespace and the original 'root' namespace.
With various versions of wpa_supplicant tested, after an IWD GO tears
the group down, the wpa_supplicant P2P client will not immediately
signal that the group has disappeared but will at least wait for the
lost beacon signal, wait some more and try reconnecting and all that
takes it 10s or a little longer. Possibly sending Deauthenticate frames
to clients first would improve this.
mac80211_hwsim has a funny quirk with multiple addresses in
radios. Some operations require address index zero, some index
one. And these addresses (possibly a result of how test-runner
initializes radios) sometimes get mixed up. For example scan
results may show a BSS address as 02:00:00:00:00:00, while the
next test run shows 42:00:00:00:00:00.
Ultimately, sending out frames requires the first nibble of the
address to be 0x4 so to handle both variants of addresses described
above hwsim.py was updated to always bitwise OR the first byte
with 0x40.
The idea of this test is valid but it is extremely timing dependent
which simply isn't testable on all machines. Removing this test
at least until this can be tested reliably.
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 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.
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.
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.
