37bccfcab8 DPP3: Push button bootstrap mechanism
Add support to use a push button -based bootstrap mechanism with DPP.
The new DPP_PUSH_BUTTON control interface command enables this mode on
the AP/hostapd and station/wpa_supplicant. This goes through the
following sequence of events: a suitable peer in active push button mode
is discovered with session overlap detection, PKEX is executed with
bootstrap key hash validation, DPP authentication and configuration
exchanges are performed.

a6d157b6f6 DPP: Start a listen operation for GAS server if needed
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.

033ad6ffaa DPP: Allow Configurator parameters to be provided during config exchange
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
(upper layer processing; potentially including user interaction)
CTRL: DPP_CONF_SET peer=2 conf=sta-sae ssid=736165 pass=70617373776f7264
<3>DPP-CONF-SENT

For example for an Initiator that can act both as a Configurator and an
Enrollee in a case where the Initiator becomes the Enrollee:

CTRL: DPP_AUTH_INIT peer=1 role=either conf=query
<3>DPP-CONF-RECEIVED

Add new control interface commands "DPP_NFC_HANDOVER_REQ own=<id>
uri=<URI>" and "DPP_NFC_HANDOVER_SEL own=<id> uri=<URI>" to support NFC
negotiated connection handover. These commands are used to report a DPP
URI received from a peer NFC Device in Handover Request and Handover
Select messages. The commands return peer bootstrapping information ID
or FAIL on failure. The returned ID is used similarly to any other
bootstrapping information to initiate DPP authentication.

e780b4bf20 DPP: Bootstrapping via NFC URI Record
This extends hostapd and wpa_supplicant DPP implementation to allow the
bootstrapping URI to be generated for and parsed from an NFC Tag with an
NFC URI Record. This is similar to the way the bootstrapping URI is used
with QR Code for unidirectional authentication.

The DPP_BOOTSTRAP_GEN command uses "type=nfc-uri" to request the URI to
be assigned for NFC URI Record. In practice, the URI is generated
identically to the QR Code case, but the internal entry maintains the
NFC-URI type.

A new command "DPP_NFC_URI <uri>" can now be used to parse the URI read
from an NFC Tag with the NFC URI Record. This is similar to the
DPP_QR_CODE command.

Other commands (mainly, DPP_LISTEN and DPP_AUTH_INIT) are used for NFC
URI in the same way as they are used for QR Code.

Merge the practically copy-pasted implementations in wpa_supplicant and
hostapd into a single shared implementation in dpp.c for managing
configurator and boostrapping information. This avoid unnecessary code
duplication and provides a convenient location for adding new global DPP

8179ae3a2a DPP: Support retrieving of configurator's private key
To retain configurator information across hostapd/wpa_supplicant
restart, private key need to be maintained to generate a valid pair of
authentication keys (connector, netaccess_key, csign) for new enrollees
in the network.

Add a DPP_CONFIGURATOR_GET_KEY control interface API through which the
private key of an existing configurator can be fetched.

Command format:
DPP_CONFIGURATOR_GET_KEY <configurator_id>

The output from this command can then be used with
"DPP_CONFIGURATOR_ADD key=<hexdump>" to create the same key again.

c1d3773967 DPP: Stop authentication exchange of DPP_STOP_LISTEN
Previously, this command stopped listen operation immediately, but if
there was an ongoing authentication exchange, a new listen operation was
started. This is not really expected behavior, so stop the
authentication exchange first with this command to avoid restarting
listen operation.

Add wpa_supplicant control interface commands for parsing the bootstrap
info URI from a QR Code (get peer public key) and to generate a new
bootstrap info with private key for local use. The optional
key=<hexdump> argument to the DPP_BOOTSTRAP_GEN command can be used to
specify the bootstrapping private key in OpenSSL ECPrivateKey DER
encoding format. This results in the local bootstrapping information
entry being created with the specified key instead of generating a new
random one.
