85fd8263a5 DPP: Use Transaction ID in Peer Discovery Request/Response frames
DPP tech spec changed the contents of these frames by replacing the
public key hash attributes with a Transaction ID attribute that gets
copied from the request to the response to identify the transaction in a
simpler manner.

b5bf84ba39 WNM: Differentiate between WNM for station and for AP in build
Previously, CONFIG_WNM enabled build that supports WNM for both
station mode and AP mode. However, in most wpa_supplicant cases only
station mode WNM is required and there is no need for AP mode WNM.

Add support to differentiate between station mode WNM and AP mode
WNM in wpa_supplicant builds by adding CONFIG_WNM_AP that should be
used when AP mode WNM support is required in addition to station mode
WNM. This allows binary size to be reduced for builds that require
only the station side WNM functionality.

922dcf1b45 RRM: Remove duplicate frequencies from beacon report scan request
When setting the frequencies for beacon report request scan, it is
possible that a frequency is added twice (e.g., when the same channel
appears both in the channel field and in the AP channel report
subelement). This may cause the scan request to fail.
Make sure the frequencies array contains no duplications before
requesting the scan.

705e2909c6 RRM: Send response when Beacon report request is not supported/refused
Send Radio Measurement response with measurement mode set to reject
in the following cases:
 1. Reporting conditions is not supported.
 2. No valid channels found for the measurement

Sending a response with an incapable indication will stop the AP from

in IEEE Std 802.11-2016, 11.11.6.

51143af7e7 wpa_cli: Fix global control interface for STA-FIRST/STA-NEXT
If global control interface is used and wlan doesn't support P2P,
   wpa_s->global->p2p == NULL, and log shows:
wpa_supplicant: Failed to create interface p2p-dev-wlan0: -5 (I/O error)
wpa_supplicant: nl80211: Failed to create a P2P Device interface p2p-dev-wlan0

Then STA-FIRST/STA-NEXT is not going to redirect to any interface,
making update_stations(ctrl_conn) is stuck in never-ending loop:

23eead4d74 RRM: Filter scan results by parent TSF only if driver supports it
Scan results with parent TSF older than the scan start TSF are not added
to the beacon report since they are considered as scan results from
previous scans. However, for drivers that report the scan start TSF but
not the parent TSF of each scan result, the parent TSF will be zero so
valid scan results will be dropped.

Fix this by filtering scan results by the parent TSF only if the
driver supports reporting the parent TSF for each scan result.

supports DFS offload, the frequency was rejected in

da143f7fb9 FILS: Fix EVENT_ASSOC processing checks for driver-SME
Commit 5538fc9309 ('FILS: Track completion

for calling wpa_supplicant_event_assoc_auth() from EVENT_ASSOC handling
in case of FILS-completion with driver-based-SME. However, that checked
what placed outside the data != NULL case while data != NULL needs to
apply for this case as well due to wpa_supplicant_event_assoc_auth()
behavior. Move the data != NULL check to apply to both cases to avoid
potentially issues if a driver interface were to return EVENT_ASSOC
without the associate data. (CID 164708)

d4d76d9835 Fix offchannel TX done handling for sequence of TX frames
There could be multiple pending TX operations and if the earlier ones
have used wait_time, but the last one did not, the driver call for
canceling pending wait was not done. This could result in the driver
getting stuck waiting for the previously scheduled wait time and not
being able to do new operations until that. Fix this by canceling the
wait if any of the past offchannel_send_action() calls since the last
offchannel_send_action_done() used non-zero wait_time.

This was showing up as issues in certain DPP Public Action frame
sequences when the same offchannel operation is used with multiple
frames and the last frame in the sequence does not need wait_time.

618aa22900 P2P: Fix p2p_in_provisioning clearing in failure case
wpa_s->p2p_in_provisioning needs to be cleared when group formation
fully completes. The change to postpone GO side handling to the first
data connection in commit 41f853235f
('P2P: Extend group formation timeout on GO to first data connection')
resulted in making this not happen in one P2P Client side case: EAP-WSC
timeout in PBC case. While that is quite special case since it requires
30 second timeout without receiving new EAPOL frames and not getting
disassociation, it can apparently happen in some cases in practice. This
would result in new P2P operations (e.g., P2P_FIND) getting rejected
until wpa_supplicant is restarted.

Fix this by clearing wpa_s->p2p_in_provisioning whenever processing a
group formation failure case. For group formation success,
wpa_s->p2p_in_provisioning is left set to non-zero value to avoid
breaking the earlier limits on the GO side.

3c2bd55f03 P2P: wpas_p2p_select_go_freq() to check for supported pref_freq
This commit is similar to the commit
783c2920cc ('P2P: Check if the pref_freq
reported by the driver supports P2P') but extends the check for
supported pref_freq to wpas_p2p_select_go_freq().

This avoids issues with P2P_GROUP_ADD ending up selecting an unexpected
channel when get_pref_freq_list() (i.e.,
QCA_NL80211_VENDOR_SUBCMD_GET_PREFERRED_FREQ_LIST) is used. Filter the
list by removing channels that do not allow P2P operation at all.
Previously, only the explicitly disallowed channels were removed and
that could have resulted in selecting an operating channel that is not
allowed for P2P and failing to complete the operation to start the
group.
