DPP: Clear push button announcement state on wpa_supplicant FLUSH
This was already done in hostapd and same is needed for wpa_supplicant
to avoid testing issues due to session overlap detection from previous
test cases.
DPP: Event message for indicating when Relay would need a Controller
The new DPP-RELAY-NEEDS-CONTROLLER control interface event can be used
to trigger mDNS discovery of a Controller to see if such a connection
can be established automatically at the time an Enrollee is trying to
initiate an operation.
DPP: Allow Relay connections to Controllers to be added and removed
The new control interface commands "DPP_RELAY_ADD_CONTROLLER <IP addr>
<PK hash>" and "DPP_RELAY_REMOVE_CONTROLLER <IP addr>" can now be used
to dynamically add and remove connections to Controllers for the cases
where the connection is initialized through a DPP Public Action frame
(i.e., Controller as the Responder).
DPP: Advertise Configurator connectivity on Relay automatically
Instead of requiring explicit configuration through
dpp_configurator_connectivity=1, advertise Configurator connectivity
automatically if a Relay is configured with a Controller that can
operate as a Responder.
DPP: Dynamic Controller initiated connection on Relay
Accept an incoming TCP connection from a Controller in a Relay that is
configured with dpp_relay_port even if that Controller is not configured
with a dpp_controller parameter. This allows more dynamic Controller
initiated operations, e.g., when using mDNS to discover a Relay.
This type of a dynamic Controller entry will not be used for exchanges
that are initiated by an Enrollee (i.e., based on a DPP Public Action
frame received by the Relay).
DPP3: Fix push button boostrapping key passing through PKEX
When PKEX was started through the push button mechanism, the own
bootstrapping key was not bound correctly to the Authentication phase
information and that ended up in incorrectly generating a new
bootstrapping key for the Authentication exchange. Fix this by added the
needed own=<id> parameter into the cached parameters when using push
button.
The peer=<id> information about the specific boostrapping key provided
through PKEX was added for Public Action frame cases, but the TCP
variant did not do same. Add the same information there to maintain
knowledge of the specific peer bootstrapping key from PKEX to
Authentication exchange.
Extend DPP push button support in wpa_supplicant to allow the role of
the Configurator to be used. This provides similar functionality to the
way the DPP_PUSH_BUTTON command in hostapd worked when providing the
configuration parameters with that command (instead of building the
config object based on current AP configuration).
DPP: Recognize own PKEX Exchange Request if it ends up being received
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.
This gets the Controller (DPP-over-TCP) sequence closer to the one used
with Public Action frames and makes it easier for upper layer components
to share the same design for tracking operation status.
DPP: Allow Controller to initiate PKEX through Relay
Relay will need to allow the PKEX Exchange Response message to be
handled similarly to the Authentication Response message to allow this
sequence to be completed successfully.
DPP: Delete PKEX code and identifier on success completion of PKEX
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.
tests: Allow DPP_PKEX_REMOVE success in dpp_pkex_hostapd_errors
This is in preparation to allow the implementation in hostapd to be
changed to accept removal of PKEX information without indicating an
error after it have been automatically removed at the successful
completion of PKEX.
The new global configuration parameter
dpp_connector_privacy_default=<0/1> can now be used to set the default
value for the dpp_connector_privacy parameter for all new networks
provisioned using DPP.
Add a privacy protecting variant of the peer introduction protocol to
allow the station device to hide its Connector from 3rd parties. The new
wpa_supplicant network profile parameter dpp_connector_privacy=1 can be
used to select this alternative mechanism to the peer introduction
protocol added in the initial release of DPP.
It should be noted that the new variant does not work with older DPP APs
(i.e., requires support for release 3). As such, this new variant is
disabled by default.
DPP: Allow 3rd party information to be added into config object
This allows the DPP Configuration Object from a Configurator to be
extended with 3rd party information. This information can be provided as
a part of the existing configuration specification mechanisms with the
new extra_name=<string> and extra_value=<hexdump encoded JSON>.
DPP: Allow 3rd party information to be added into config request obj
This allows the DPP Configuration Request Object from an Enrollee to be
extended with 3rd party information. The new dpp_extra_conf_req_name and
dpp_extra_conf_req_value configuration parameters specify the name of
the added JSON node and its contents. For example:
dpp_extra_conf_req_name=org.example
dpp_extra_conf_req_value={"a":1,"b":"test"}
Add a new vendor attribute QCA_WLAN_VENDOR_ATTR_CONFIG_DBAM to
configure Dedicated Bluetooth Antenna Mode (DBAM). It is used to
switch between dedicated antenna mode for BT and COEX shared
antenna mode for WLAN and BT.
DPP: Allow AP/Relay to be configured to listed for new TCP connections
This extends Relay functionality to allow a Controller to intitiate a
new DPP exchange in addition to the previously supported case where the
exchange was initiated through a DPP Public Action frame.
DPP3: Allow external configuration to be specified on AP for PB
While the most likely production use case for DPP push button is to
provision the AP's current configuration, there might be some use cases
for providing different configuration. Add possibility for doing this by
extending the DPP_PUSH_BUTTON command to accept an optional set of
parameters similarly to the other DPP commands for the Configurator.
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.
Add AP and STA specific P802.11az security capabilities (vendor command)
Add feature capability indication for P802.11az security for the drivers
to advertise capabilities such as secure LTF support, secure RTT
measurement exchange support, and protection of range negotiation and

alternative to the upstream nl80211 mechanism that is not specific to
the operating mode.

Add QCA vendor interface for PASN offload to userspace
Define QCA vendor interface for PASN offload to userspace from the driver.
The driver can send this command as an event to a userspace component to
perform PASN authentication with a list of peers with which the driver
needs to do ranging. The userspace component, if capable of performing
PASN handshake, can perform PASN handshake with all the peer devices and
set the relevant keys by sending the
QCA_NL80211_VENDOR_SUBCMD_SECURE_RANGING_CONTEXT command for each peer
to the driver.
Once PASN handshake is completed with all requested peers, the userspace
component sends consolidated status for all the peers to the driver. The
consolidated report is required for the driver to understand that the
PASN handshake process is complete and whether it succeeded/failed for
each of the peers it was requested for. The secure ranging context is
configured only for the peers with which the PASN handshake succeeded.
When the driver requests PASN keys, the userspace component can set the
keys from its cache if those keys have not already expired and were
derived with the same source MAC address that is requested by the driver
instead of doing the full PASN handshake again.
If the driver detects that current keys of a peer are not valid anymore,
it sends a notification to userspace using the
QCA_NL80211_VENDOR_SUBCMD_PASN command and setting the action to
QCA_WLAN_VENDOR_PASN_ACTION_DELETE_SECURE_RANGING_CONTEXT. The userspace
component should delete the corresponding keys from its cache.
