d514b50265 WNM: Collocated Interference Reporting
Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.

For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".

For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".

This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

91073ccaaa OWE: Attempt more scans for OWE transition SSID if expected BSS not seen
This commit introduces a threshold for OWE transition BSS selection,
which signifies the maximum number of selection attempts (scans) done
for finding OWE BSS.

This aims to do more scan attempts for OWE BSS and eventually select the
open BSS if the selection/scan attempts for OWE BSS exceed the
configured threshold.

af835d75b7 FILS: Fix FILS connect failures after ERP key invalidation
If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.

Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

37547ad63c wpa_supplicant: Increase authentication timeout if CAC is started
Timeout is increased by dfs_cac_ms from channel data, or by max CAC time
(10 minutes) if dfs_cac_ms is not defined. This is needed for some more
complex cases, e.g., when STA is acting as an active slave with DFS
offload enabled and decided to start CAC after receiving CONNECT
command, in such a case the 10 second timeout is too small and
wpa_supplicant need to wait for CAC completion or CAC timeout (up to 10
minutes).

Without such timeout modification wpa_supplicant will be unable to
connect to an AP on DFS channel, since the default authentication
timeout (10 s) is smaller than the minimum CAC time (60 s).

Tested with nl80211 DFS offload implementation.

6a252ece24 DPP: Fix GAS query removal race condition on DPP_STOP_LISTEN
If a DPP_STOP_LISTEN call happens to be received when there is a pending
gas-query radio work that has not yet been started, it was possible for
gas_query_stop() to go through gas_query_done() processing with
gas->work == NULL and that ended up with the pending GAS query getting
freed without removing the pending radio work that hold a reference to
the now freed memory. Fix this by removing the pending non-started radio
work for the GAS query in this specific corner case.

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.

4d77d80edd mesh: Add MESH_PMKSA_GET/ADD commands
These commnds are mesh version of PMKSA_GET/ADD commands. So the usage
and security risk is similar to them. Refer to
commit 3459381dd2 ('External persistent
storage for PMKSA cache entries') also.

The MESH_PMKSA_GET command requires peer MAC address or "any" as an
argument and outputs appropriate stored PMKSA cache. And the
MESH_PMKSA_ADD command receives an output of MESH_PMKSA_GET and re-store
the PMKSA cache into wpa_supplicant. By using re-stored PMKSA cache,
wpa_supplicant can skip commit message creation which can use
significant CPU resources.

The output of the MESH_PMKSA_GET command uses the following format:
<BSSID> <PMKID> <PMK> <expiration in seconds>

The example of MESH_PMKSA_ADD command is this.
MESH_PMKSA_ADD 02:00:00:00:03:00 231dc1c9fa2eed0354ea49e8ff2cc2dc cb0f6c9cab358a8146488566ca155421ab4f3ea4a6de2120050c149b797018fe 42930

6e374bd44d Ignore scan results from ongoing scan when FLUSH command is issued
This makes wpa_supplicant behavior more consistent with FLUSH command to
clear all state. Previously, it was possible for an ongoing scan to be
aborted when the FLUSH command is issued and the scan results from that
aborted scan would still be processed and that would update the BSS
table which was supposed to cleared by the FLUSH command.

This could result in hwsim test case failures due to unexpected BSS
table entries being present after the FLUSH command.
