Just like with WPA-PSK and keyids it may be desired to identify
connecting clients to provide additional network filtering.
This does:
- extend DPP_EVENT_AUTH_SUCCESS to expose public
key hash of the peer so the system can pick it
up and use for identification later
- store public key hash in PMKSA from DPP Network
Intro for later use
- extend sta mib to print out the dpp_pkhash
from PMKSA if present
- extend AP_STA_CONNECTED to include the
dpp_pkhash from PMKSA if present

This prevents attempts of trying to use PMKSA caching when the existing
entry was created using a different MAC address than the one that is
currently being used. This avoids exposing the longer term PMKID value
when using random MAC addresses for connections.
In practice, similar restriction was already done by flushing the PMKSA
cache entries whenever wpas_update_random_addr() changed the local
address or when the interface was marked down (e.g., for an external
operation to change the MAC address).

It is possible for a Controller to receive a copy of its own PKEX
Exchange Request in the case where the Controller is initiating a PKEX
exchange through a Relay. The Configurator role in the device would have
a matching PKEX code in that case and the device might reply as a PKEX
responder which would result in going through the exchange with the
Controller device itself. That is clearly not desired, so recognize this
special case by checking whether the Encrypted Key attribute value
matches a pending locally generated one when processing a received PKEX
Exchange Request.

We are not supposed to reuse these without being explicitly requested to
perform PKEX again. There is not a strong use case for being able to
provision an Enrollee multiple times with PKEX, so this should have no
issues on the Enrollee. For a Configurator, there might be some use
cases that would benefit from being able to use the same code with
multiple Enrollee devices, e.g., for guess access with a laptop and a
smart phone. That case will now require a new DPP_PKEX_ADD command on
the Configurator after each completion of the provisioning exchange.

The offchannel frame TX wait was stopped whenever processing
DPP_STOP_LISTEN in most cases. However, there was a corner case on the
Responder side where this operation was skipped after PKEX was completed
successful and the Authentication Request frame had not yet been
received from the Initiator.
While this does not normally cause any significant issue, this could
result in unexpected behavior especially in test cases that run multiple
DPP PKEX operations in a row since the start of a new TX operation might
get delayed while waiting for the previous TX-wait to complete.

This is needed since the gas_query_req() operation could remain waiting
indefinitely for the response if the Configurator keeps sending out
comeback responses with additional delay. The DPP technical
specification expects the Enrollee to continue sending out new Config

last expected new Config Request for the Configurator to determine what
kind of configuration to provide.

Instead of depending on the TX-wait-response-time to be sufficient to
cover the full GAS exchange, start an ongoing listen operation on the
negotiation channel (if no such listen operation is already in place) to
allow the configuration exchange to take longer amount of time. This is
needed for cases where the conf=query is used to request Configurator
parameters from upper layers and that upper layer processing (e.g., user
interaction) takes significant amount of time.
Signed-off-by: Jouni Malinen <quic_jouni@quicinc.com>
This provides an alternative mechanism for upper layer components to
control configuration parameters to be used by the local Configurator.
Instead of the previously used design where the Configurator parameters
had to be provided before initiating the DPP Authentication exchange,
the new alternative approach allows the DPP Authentication exchange to
be started before any Configurator parameters have been determined and
wpa_supplicant will then request the parameters once the DPP
Configuration Request has been received from the Enrollee. This allows
the Config Request information to be used at upper layers to determine
how the Enrollee should be configured.
For example for an Initiator:
CTRL: DPP_QR_CODE <URI from Responder/Enrollee>
CTRL: DPP_AUTH_INIT peer=1 conf=query
<3>DPP-CONF-NEEDED peer=1 src=02:00:00:00:00:00 net_role=sta name="Test" opclass=81,82,83,84,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130 mud_url=N/A
(upper layer processing; potentially including user interaction)
CTRL: DPP_CONF_SET peer=1 conf=sta-sae ssid=736165 pass=70617373776f7264
<3>DPP-CONF-SENT
For example for a Responder:
CTRL: SET dpp_configurator_params conf=query
CTRL: DPP_LISTEN 2412 role=configurator
<3>DPP-CONF-NEEDED peer=2 src=02:00:00:00:01:00 net_role=sta name="Test" opclass=81,82,83,84,115,116,117,118,119,120,121,122,123,124,125,126,127,128,129,130 mud_url=N/A

CTRL: DPP_CONF_SET peer=2 conf=sta-sae ssid=736165 pass=70617373776f7264
<3>DPP-CONF-SENT

The chirp scan could override the scan_res_handler. This could lead to
wpa_supplicant getting stuck in a scanning state while not scanning at
all until forced to, e.g., via an explicit SCAN control command.
The condition for trigerring this problem in my testing was when
(interface_count % 3) == 2. This introduced a two second delay before
actual scan was triggered after starting the wpa_supplicant instance up.
If DPP chirping was requested fast enough, in between the queueing and
triggering, it would punt the scan request, never to be resumed again.
Chirp scan handler wouldn't resume it leaving wpa_supplicant
