If a test does not need any hostapd instances but still loads
hostapd.py for some reason we want to gracefully throw an
exception rather than fail in some other manor.
Add the new wpas.Wpas class roughly based on hostapd.HostapdCLI but only
adding methods for the P2P-related stuff.
Adding "wpa_supplicant" to -v will enable output from the wpa_supplicant
process to be printed and "wpa_supplicant-dbg" will make it more verbose
("wpa_supplicant" is not needed because it seems to be automatically
enabled because of the glob matching in ctx.is_verbose)
Add support for a WPA_SUPPLICANT section in hw.conf where
'radN=<config_path>' lines will only reserve radios and create
interfaces for the autotest to be able to start wpa_supplicant on them,
i.e. this prevents iwd or hostapd from being started on them but doesn't
start a wpa_supplicant instance by itself.
The host systems configuration directories for IWD/EAD were
being mounted in the virtual machine. This required that the
host create these directories before hand. Instead we can
just set up the system and IWD/EAD to use directories in /tmp
that we create when we start the VM. This avoids the need for
any host configuration.
When the SignalLevelAgent doc blurb was moved to station-api.txt it
seems the interface was changed to Station.SignalLevelAgent in some
places but not in most and not in the code. Also fix the pointers to
the doc file.
periodic_scan_stop is called whenever we exit the autoscan state but a
periodic scan may not be running at the time. If we have a
user-triggered scan running, or the autoconnect_quick scan, and we reset
Scanning to false before that scan finished, a client could en up
calling GetOrderedNetwork too early and not receiving the scan results.
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.
