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.

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.

For hidden GBK encoding of a Chinese SSID, both the UTF-8 and GBK
encoding profiles are added into wpa_supplicant to make sure the
connection succeeds. In this situation, wpa_supplicant_select_network()
will not be called so current_ssid is NULL when association begins.
Android monitors the WPA_EVENT_STATE_CHANGE event to get the SSID and
BSSID. When connecting to a Chinese SSID, in case of association
rejection happens, Android will report null SSID to OEM APP because
current_ssid is updated after wpa_supplicant_set_state(wpa_s,
WPA_ASSOCIATING), which may cause confusion.
Fix this by setting the current_ssid before changing state to
ASSOCIATING.

The initial OCV implementation validating this field in the OCI element
for both the 80+80 MHz and 160 MHz cases. However, IEEE Std 802.11-2020,
12.2.9 ("Requirements for Operating Channel Validation") limitis that
verification step for the 80+80 MHz case: "Verifying that, if operating
an 80+80 MHz operating class, the frequency segment 1 channel number ...
is equal to the Frequency Segment 1 Channel Number field of the OCI."
Remove this check for the 160 MHz case since there has been incorrect
interpretation on how the Frequency Segment 1 Channel Number field of
the OCI element is set in this case (using VHT rules for CCFS2). The
modified validation step is meets the real need here, is compliant with
the standard, and avoids potential interoperability issues when using
contiguous 160 MHz channels.
