This was copy pasted from the autoconnect test, and depending on
how the python module cache is ordered can incorrectly use the
wrong test class. This should nothappen because we insert
the paths to the head of the list but for consistency the class
should be named something that reflects what the test is doing.
Add a fake resolvconf executable to verify that the right nameserver
addresses were actually committed by iwd. Again use unique nameserver
addresses to reduce the possibility that the test succeeds by pure luck.
In static_test.py add IPv6. Add comments on what we're actually testing
since it wasn't very clear. After the expected ACD conflict detection,
succeed if either the lost address was removed or the client disconnected
from the AP since this seems like a correct action for netconfig to
implement.
In iwd.py make sure all the static methods that touch IWD storage take the
storage_dir parameter instead of hardcoding IWD_STORAGE_DIR, and make
sure that parameter is actually used.
Create the directory if it doesn't exist before copying files into it.
This fixes a problem in testNetconfig where
`IWD.copy_to_storage('ssidTKIP.psk', '/tmp/storage')`
would result in /tmp/storage being created as a file, rather than a
directory containing a file, and resulting in IWD failing to start with:
`Failed to create /tmp/storage`
runner.py creates /tmp/iwd but that doesn't account for IWD sessions
with a custom storage dir path.
Extend test_ip_address_match to support IPv6 and to test the
netmask/prefix length while it reads the local address since those are
retrieved using the same API.
Modify testNetconfig to validate the prefix lengths, change the prefix
lengths to be less common values (not 24 bits for IPv4 or 64 for IPv6),
minor cleanup.
Since commit 922fa099721903b106a7bc1ccd1ffe8c4a7bce69 in hostap, our
setting of config_methods on P2P-client interface was ignored. Work
around that commit, in addition to the previous workaround we have in
this test, to again ensure the correct config_methods value is used.
Similarly to ofono/phonesim allow tests to be skipped if wpa_supplicant
is not found on the system.
This required some changes to DPP/P2P where Wpas() should be called first
since this can now throw a SkipTest exception.
The Wpas class was also made to allow __del__ to be called without
throwing additional exceptions in case wpa_supplicant was not found.
This allows the EAP tests to pass, but the fix really needs to be in
hostapd itself. Hostapd currently tries to lookup the EAP session
immediately after receiving EAPOL_REAUTH. This uses the identity
it has stored which, in the case of PEAP/TTLS, will always be a phase2
identity. During this initial lookup hostapd hard codes the identity
to be phase1 which is not true for PEAP/TTLS, and the lookup fails.
The current way this was being done was to import collections and
use collections.Mapping. This has been deprecated since python 3.3
but has worked up until python 3.10. After python 3.10 this will
no longer work, and Mapping must be imported from collections.abc.
This was passing IFNAME= along with EAPOL_REAUTH which does not work
in the context of a hostapd socket where the iface is already implied.
This fixes that issue as well as resets the events array and actually
waits for the required events afterwards.
The signal agent notifications were changed which breaks this test.
Specifically commit ce227e7b94 sends a notification when connected
which breaks the 'agent.calls' check. Since this check is done both
after connecting and once already connected the initial value may
be 1 or 0. Because of this that check was removed entirely.
This test was just piping the PSK files into /tmp/iwd/ssidCCMP.psk
which is a bit fragile if the storage dir was ever to change. Instead
use copy_to_storage and the 'name' keyword to copy the file.
Use scapy library which allows one to easily construct and fudge various
network packets. This makes constructing spoofed packets much easier
and more readable compared to hex-encoded, hand-crafted frames.
The TA/BSSID addresses of spoofed disassociate frames were set
incorrectly. They should be using the 02:00:00:XX:XX:XX address, but
instead were being converted over to 42:00:00:XX:XX:XX address
update_config=1 lets wpa_supplicant write config changes
to the config file. In the real world this is what you want
so your DPP credentials are persistant. But for testing this
is not correct since multiple tests use the same config file
and expect it to be pristine.
Occationally wpa_supplicant was connecting to the AP without
running DPP because the config already had the network
credentials.
There is really no reason to have hwsim create interfaces automatically
for test-runner. test-runner already does this for wpa_supplicant and
hostapd, and IWD can create the interface itself.
The test was rekeying in a loop which ends up confusing hostapd
depending on the timing of when it gets the REKEY command and any
responses from IWD. UML seemed to handle this fine but not QEMU.
Instead delay the rekey a bit to allow it to fully complete before
sending another.
Similarly to hostapd.wait_for_event, IWD's variant needed to act on
an IO watch because events were being received prior to even calling
wait_for_event.
With how fast UML is hostapd events were being sent out prior to
ever calling wait_for_event. Instead set an IO watch on the control
socket and cache all events as they come. Then, when wait_for_event
is called, it can reference this list. If the event is found any
older events are purged from the list.
The AP-ENABLED event needed a special case because hostapd gets
started before the IO watch can be registered. To fix this an
enabled property was added which queries the state directly. This
is checked first, and if not enabled wait_for_event continues normally.
This removes prints which were never supposed to make it upstream as
well as changes sleep() to wd.wait() as well as increase the wait
period to fix issues with how fast UML runs the tests.
Any test using assertTrue(hostapd.list_sta()) improperly has been
replaced with wait_for_event(). There were a few places where this
was actually ok (i.e. IWD is already connected) but most needed to
be changed since the check was just after IWD connected and hostapd's
list_sta() API may not return a fully updated list.
- Setting the IP address was resulting in an error:
Error: any valid prefix is expected rather than "wln58".
This is fixed by reordering the arguments with the IP address first
- Remove the sleep, and use non_block_wait to wait for the IPv6 address
to be set.
Before setting the address, wait for the interface to go down. This
fixes somewhat rare cases where setting the address returns -EBUSY
and ultimately breaks the neighbor reports.
All tests which could avoid calling scan() directly have been
changed to use the 'full_scan' argument to get_ordered_network.
This was done because of unreliable scanning behavior on slower
systems, like VMs. If we get unlucky with the scheduler some beacons
are not received in time and in turn scan results are missing.
Using full_scan=True works around this issue by repeatedly scanning
until the SSID is found.
When configuring wpa_supplicant all we care about is that it
received the configuration object. wpa_supplicant takes quite a bit
of time to connect in some cases so waiting for that is unneeded.
This also increases the DPP timeout which may be required on slower
systems or if the timing is particularly unlucky when receiving
frames.
Change a few critical checks that were failing sometimes:
- A few asserts were changed to wait_for_object_condition
- A 15 second timeout was removed (default used instead)
- Do a full scan at beginning of each test to clear any
cached BSS's. The second test run was getting stale results
and the RSSI values were not expected.
This was not being properly honored when existing networks were
already populated. This poses an issue for any test which uses
full_scan after setting radio values such as signal strength.
If an event is in response to some command which is returning an
unexpected value (unexpected with respect to wpas.py) handle_eow
would raise an exception.
Specifically with DPP this was being hit when the URI was being
returned.
Adds a new wait argument which, if false, will call the DBus method
and return immediately. This allows the caller to create multiple
radios very quickly, simulating (as close as we can) a wifi card
with dual phy's which appear in the kernel simultaneously.
The name argument was also changed to be mandatory, which is now
required by hwsim.
