3) remove waits
4) eliminate a race condition on get_ordered_networks()
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.
All handshake packet handling has been removed from ap and
moved to eapol. After association, the AP registers a new
authenticator state machine which handles the AP side of
the handshake. AP will receive a handshake event once the
4-way handshake is complete.
Includes:
- support for handling ptk 2/4 and 4/4. Also sending 1/4 and 3/4.
- new API to register an authenticator SM. This automatically
sends 1/4 to kick off authentication with an sta.
These checks allow both a station and authenticator to use
the same netdev key install functions. For NEW_KEY and
SET_STATION, the iftype is checked and either handshake->aa
or ->spa is used as the station address for the KEY/STATION
commands. Also, in the failure cases, a disconnect command
is issued only if the iftype is station as this doesn't
apply to AP.
Handshake related netdev events were removed in favor of
handshake events. Now events will be emitted on the handshake
object related to the 4-way handshake and key settings. Events
are:
HANDSHAKE_EVENT_STARTED
HANDSHAKE_EVENT_SETTING_KEYS
HANDSHAKE_EVENT_COMPLETE
HANDSHAKE_EVENT_FAILED
Right now, since netdev only operates in station mode, nothing
listens for COMPLETE/FAILED, as device/wsc gets notified by the
connect_cb when the connection was successful. The COMPLETE/
FAILED were added in preperation for AP moving into eapol/netdev.
