This removes the need for duplicate code in AP/netdev for issuing
a DEL_STATION command. Now AP can issue a DEL_STATION with
netdev_del_station, and specify to either disassociate or deauth
depending on state.
If netdev fails to set the keys, there was no way for device/ap to
know. A new handshake event was added for this. The key setting
failure function was also fixed to support both AP/station iftypes.
It will now automatically send either a disconnect or del_station
depending on the interface type.
In similar manner, netdev_handshake_failed was also modified to
support both AP/station iftypes. Now, any handshake event listeners
should call netdev_handshake_failed upon a handshake failure
event, including AP.
If device is already disconnected or in autoconnect mode, don't return
an error if .Disconnect is called. Instead simply silently return
success after disabling autoconnect.

2) add try, except block for the clean termination of iwd in
the case of a failure
3) increase the max execution time to help with valgrind

list_devices() was updated to take an integer rather than a bool
for the wait_to_appear argument. This updates any tests that
explicily passed True/False as the argument to list_devices.
The list_devices API has a race condition where sometimes it will
return zero or less than the expected number of devices and fail
the test. A fix is in place for when only a single devices is
expected, but some tests expect more than one device. This changes
wait_to_appear to an integer, and the caller can specify the number
of devices they expect to get back. The default stays as it was,
zero or "return cached devices".
This is a fixup for the AP code merge. wsc.c never registered
for handshake events, so in case of failure it was never calling
netdev_handshake_failed, which caused a double free.
Many APs don't send properly zerod key_iv elements in EAPoL-Key frames.
In the past iwd has complained, but this broken behavior is so
prevalent, that it is likely a lost cause.
This patch takes out these warnings
Right now iwd uses Control Port over NL80211 feature if the kernel /
driver supports it. On some kernels this feature is still buggy, so add
an iwd.conf entry to allow the user to override id.
For now the default is to disable this feature until it is more stable.
The single AP test worked fine, but adding a failure test caused some
problems. Since the kernel is never restarted between tests it maintains
old stale scan results from the previous test. This was causing an
assert to sometimes fail in the second test being run because it was
returning > 1 ordered networks. This change iterates through the ordered
network list and chooses the appropriate network rather than assuming
get_ordered_networks() will always return only one network object
Now, a user can setup an AP as follows:
- Set device "Mode" to ap (ap interface will appear on bus)
- call "Start()" on AP interface
Issuing "Stop()" on the AP interface will stop and cleanup
the internal AP structures, but the AP interface will remain
up. To shutdown completely the device Mode must be switched
back to station. If the AP interface is running, the Mode can
directly be switched to station without calling Stop; this
has the same effect and will take down the AP interface.
Some of the PEAP server implementation brake the protocol
and don’t set the M flag for the first packet during the
fragmented transmission. To stay compatible with such
devices, we relax this requirement in iwd.
This patch allows alternating between the passive and active
scans taking into consideration an existence of the known
hidden networks and previous observation of them in the scan
results, as well as an ability to randomize the MAC address.
The state of scan is split between the two variables sc->state
and sc->start_cmd_id. Not checking start_cmd_id used to cause
sending a scan request while periodic scan was just triggered
resulting in EBUSY.
Instead of manually sending a deauth/disassociate to a station
during an error or removal, the kernel can do it automatically
with DEL_STATION by including the MGMT_SUBTYPE attribute. This
removes the need for ap_error_deauth_sta and introduces
ap_deauthenticate_sta. Now AP can be explicit when it chooses
to deauth or disassociate.
