When receiving a BTM request, wpa_supplicant would try to fetch new
results from the driver, and, independently of that, would also process
the latest scan results that were partially updated by the previous
fetch.
Simplify the logic by using wpa_supplicant_get_scan_results() directly
and then process the old scan data as usual. However, this data may be
outdated, so add a new heuristic to avoid roaming to a BSS if it is
either outdated or bad.
Doing this moves all scan data processing into wnm_scan_process() and
removes duplicated functionality for scan result processing in scan.c.

Avoid potential race conditions with the driver operations between
stopping an ongoing wait for responses for an offchannel TX that was
used to send Authentication Request with a request to use a different
channel for Authentication Response and the start of a new ROC on the
other channel by waiting for the TX expiration event before issuing the
ROC request.

The event indicating expiration of an offchannel TX is useful for cases
where the wait is for a frame that was explicitly requested to have the

Avoid potential race conditions with the driver operations between
cancelling an ongoing ROC that was used to receive Authentication
Request that requested a different channel to be used for the
negotiation by waiting for the ROC cancelled event before issuing the
offchannel TX command for the Authentication Response.
In addition, speed up the retry on Authentication Response in this type
of a case if the first attempt on the other channel is not AKC'ed since
it might take the peer device a bit more time to be ready to listen
there.

In some places the wrong index variable was used to access the link

With this, the i loop variable is not needed anymore. We can simply
always pass 0 to nla_nest_start(). Also, the kernel does not care about
the order that the links are provides, so just remove the special

When wpa_supplicant assigns the IP address (WFA EAPOL IP address
allocation feature), the assigned IP address of the P2P Client on the GO
side is notified in the AP-STA-CONNECTED event. So to obtain the IP info
to external programs, modify the STA authorized event to include the the
assigned IP address of the P2P Client.
Test: Establish P2P connection and verified from the logs that
the P2P Client IP address is notified.

When wpa_supplicant receives a request to start a P2P group owner on a
fixed frequency with bandwidth wider than 20 MHz, wpa_supplicant scans
for neighboring BSSs prior to starting the GO. This is done to switch
the primary/secondary channels if there are any other networks which are
operating on the same secondary channel. Though this logic is defined
for 20/40 MHz coexistence and might improve throughput, there are P2P
use cases where this logic causes problem:
1. The file transfer use case takes time to start the file transfer or
even fails when the 20/40 coex scan repeatedly fails due to an
ongoing externally triggered scan happening in the system.
2. wpa_supplicant overrides the channel which is selected by the
application based on the best channel it derived by looking into
the channel conditions. This degrades the expected throughput.
3. Latency sensitive applications experience long time to
start the group owner which gives a bad user experience.
So do not allow 40 MHz co-ex PRI/SEC switch to force a change to
Autonomous GO PRI channel when the P2P group add is called with a forced
frequency.
Test: Tested autonomous GO and confirmed from the logs that
P2P GO is not triggering 20/40 coex scan.

When the station (non-AP MLD) is associated with an AP MLD the link ID
for TDLS setup is derived from the discovery response frame and the link
ID is used in TDLS setup operation when acting as initiator. The driver
sends the received discovery response frame followed by the TDLS setup
request event. But the discovery response frame is received after the
setup request event leading to use incorrect link ID value for TDLS
setup operation causing the setup failure. Process the TDLS setup
request if the discovery response frame is received, else defer the
process until the discovery response frame is received and process the
setup request after discovery response frame is processed.

When the CHAN_SWITCH command is executed during multi BSSID case (say
BSS1, BSS2, and BSS3), if one of the BSS is disabled (say BSS2), the
CHAN_SWITCH command returns an error in BSS2 and does not proceed to the
next BSS (BSS3).
The CHAN_SWITCH command handler iterates over all configured BSSs and
attempts to send the switch_channel to each one. However, if any one of
the BSSs fails, the entire command is aborted and returns a failure.
Continue the iteration even if one BSS is failing to make sure the
configuration is applied to other BSSs.

hostapd used to require that only the PMKR1Name is included in the PMKID
List of RSNE in EAPOL-Key msg 2/4. Extend this to allow the PMKIDs that
were included in the (Re)Association Request frame to be present as long
as the correct PMKR1Name is also present. This would allow PMKSA caching
to be used in initial mobility domain association with supplicant
implementations that insert the PMKR1Name without removing the PMKIDs
used in the (Re)Association Request frame. wpa_supplicant did not use to

For some implementation, there is no link id in EAPOL event, e.g., use
drv_event_eapol_rx for receiving. Current design for such case is switch
to a link that stores the peer. However, this is error-prone because for
non-AP MLD case, sta_info is stored in all valid links but EAPOL sm is
only initialized in the association link. If EAPOL RX event is handled
in a non-association link, it will be discarded and this leads to EAPOL
timeout.
So find the association link to handle received EAPOL frame in such
case. This replaces the previously used workaround for RSN/wpa_sm for
the no link id specified case.
