ConnectHiddenNetwork can be seen a triggering this sequence:
1. the active scan,
2. the optional agent request,
3. the Authentication/Association/4-Way Handshake/netconfig,
4. connected state
Currently Disconnect() interrupts 3 and 4, allow it to also interrupt
state 1. It's difficult to tell whether we're in state 2 from within
station.c.
Allow the "hwsim_medium=no" setting in hw.conf's SETUP section to
disable starting hwsim. It looks like the packets going through
userspace add enough latency that active scans don't work, probe
responses don't arrive within the "dwell time" or probe requests are not
ACKed on time. I've tried modifying tools/hwsim.c to respond with the
HWSIM_CMD_TX_INFO_FRAME cmd as the first thing after receiving a
HWSIM_CMD_FRAME and even skipping the queue in ell/genl.c by writing the
command synchronously, but neither helped enough to make the scans work.
This does not rule out that hwsim or the way our scans are done can be
fixed and that would obviously be better than what I did in this patch.
Since our DBus API and our use cases only support initiating connections
and not accepting incoming connections we don't really need to reply to
Probe Requests on the P2P-Device interface. Start doing it firstly so
that we can test the scenario where we get discovered and pre-authorized
to connect in an autotest (wpa_supplicant doesn't seem to have a way to
authorize everyone, which is probably why most Wi-Fi Display dongles
don't do it and instead reply with "Fail: Information not available" and
then restart connection from their side) and secondly because the spec
wants us to do it.
Make sure dev->peer_list is non-NULL before using l_queue_push_tail()
same as we do when the peer info comes from a Probe Response (active
scan in Find Phase). Otherwise peers discovered through Probe Requests
before any Probe Responses are received will be lost.
The device type category array is indexed by the category ID so if we're
skipping i == 0 in the iteration, we should also skip the 0'th element
in device_type_categories.
The callback for the FRAME command was causing a crash in
wiphy_radio_work_done when not cancelled when the wiphy was being
removed from the system. This was likely to happen if this radio work
item was waiting for another item to finish. When the first one was
being cancelled due to the wiphy being removed, this one would be
started and immediately stopped by the radio work queue.
Now this crash could be fixed by dropping all frame exchange instances
on an interface that is being removed which is easy to do, but properly
cancelling the commands saves us the headache of analysing whether
there's a race condition in other situations where a frame exchange is
being aborted.
We want to use this flag only on the interfaces with one of the three
P2P iftypes so set the flag automatically depending on the iftype from
the last 'config' notification.
This extends test-runner to also use iwmon if --log is enabled.
For this case the iwmon log will be found inside each test
log directory.
A new option, --monitor <file> was added in case full logging isn't
desired (potentially for timing issues) but a iwmon log is needed.
Be aware that when --monitor is used test-runner will mount the
entire parent directory. test-runner itself will only write to the
file specified, but just know that the parent directory is available
as read-write inside the VM.
--log takes precedence over --monitor, meaning the iwmon log will
be written to <logdir>/<test>/iwmon instead of the file specified
with --monitor if both options are provided.
Convert ap_send_mgmt_frame() to use frame_xchg_start for sending frames,
this fixes among other things the ACK-received checks.
One side effect is that we're no longer sending Probe Responses with the
don't-wait-for-ack flag because frame-xchg doesn't support it, but other
AP implementations don't use that flag either.
Another side-effect is that we do use the no-cck-rate flag
unconditionally, something we may want to fix but would need to add
another parameter to frame-xchg.
The virtual environment changed slightly adding two network adatpers
which are connected to the same backend so they can communicate with
each other (basically connected to a switch). The hostapd command
line was modified to allow no interfaces to be passed in which lets
us create zero radios but still specify a radius_config file.
This module is essentially a heavily stripped down version of iwd.py
to work with EAD. Class names were changed to match EAD but basically
the EAD, Adapter, and AdapterList classes map 1:1 to IWD, Device, and
DeviceList.
This is somewhat of a hack, but the IWDDBusAbstract is a very
convenient abstraction to DBus objects. The only piece that restricts
it to IWD is the hardcoded IWD_SERVICE. Instead we can pass in a
keyword argument which defaults to IWD_SERVICE. That way other modules
(like EAD) can utilize this abstraction with their own service simply
by changing that service argument.
The interface was hard coded to wln0 which works when running single
tests but not when running multiple. Instead use the actual ifname
that hostapd is using.
Add a "psk" setting to allow the user to pass the binary PSK directly
instead of generating it from the passphrase and the SSID. In that case
we'll only send the PSK to WSC enrollees.
There has been a desire to remove the ELL plugin dependency from
IWD which is the only consumer of the plugin API. This removes
the dependency and prepares the tree for converting the existing
ofono plugin into a regular module.
sim_hardcoded was removed completely. This was originall implemented
before full ofono support purely to test the IWD side of EAP-SIM/AKA.
Since the ofono plugin (module-to-be) is now fully implemented there
really isn't a need for sim_hardcoded.
Tests that DHCP using IWD's internal netconfig functions properly.
The actual IP address assignment is not verified, but since IWD does
not signal the connection as successful unless DHCP succeeds we
can assume it was successful by checking that the device is connected.
The process of actually starting dhcpd and configuring the interfaces
is quite simple so it was left in the autotest itself. If (or when)
more tests require IP capabilities (p2p, FILS, etc) this could be
moved into test-runner itself and be made common. The reason I did not
put it in there now is a) because this is the only test and b) more
complex DHCP cases are likely to develop and may require more than this
simplistic setup (like multiple APs/interfaces)
This is just a more concise/pythonic way of doing function arguments.
Since Process/start_process have basically the same argument names
we can simplify and use **kwargs which will pass the named arguments
directly to Process(). This also allows us to add arguments to Process
without touching start_process if we need.
The AdHoc functionality in iwd.py was not consistent at all with
how all the other classes worked (my bad). Instead we can create
a very simple AdHocDevice class which inherits all the DBus magic
in the IWDDBusAbstract class.
The Started property was being set in the Join IBSS callback which
isn't really when the IBSS has been started. The kernel automatically
scans for IBSS networks which takes some time. Its better to wait
on setting Started until we get the Join IBSS event.
Commit 1f910f84b4 ("eapol: Use eapol_start in authenticator mode too")
introduced the requirement that authentication eapol_sm objects also had
to be started via eapol_start. Adhoc was never updated to do that.
