In the MLD case, the information from the transition management request
is relevant during the association process in order to filter out links
that were disallowed by the BTM request. Also, the information remains
useful should a connection attempt fail.
To enable these scenarios, keep the information around until the
connection has completed. As this might make it impossible to establish
a connection, also clear this information at the same time that a normal
BSS ignore is cleared to avoid getting stuck in case the transition
fails unexpectedly.

If the last link is dropped, it makes sense to follow the BTM procedure.
However, in that case we need to prevent reconnection to this link
specifically, while if the AP MLD is terminating we need to forbid
connecting to the AP MLD.
As such, add a new variable to track the BSSID or AP MLD MAC address.
Which one it refers to depends on whether wnm_link_removal is set.

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outdated, so add a new heuristic to avoid roaming to a BSS if it is
either outdated or bad.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.

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.

Allow the Timeout Interval Type field in the Timeout Interval element to

wpa_supplicant internal functionality to be tested.
Signed-off-by: Jouni Malinen <j@w1.fi>
In associations using PMF (IEEE 802.11w/MFP), the infrastructure
implements SA teardown protection by rejecting an (Re)Association
Request frame from an already-associated client. The AP responds with
error 30 (Association request rejected temporarily) to instruct the
(potentially spoofing) client to back off, while it issues an SA Query
procedure to the already-associated client. If the client can respond to
it within the back-off period, it considers the new association to be a
spoof attempt.
However, there are cases where a legitimate client might need to
handle this error response - consider if the STA has deauthenticated,
but the AP cannot hear it (out of range). If the MFP STA has deleted
its keys, it cannot respond to the SA Query procedure.
This association comeback process has commonly been implemented in the
driver, e.g., within mac80211 in case of the Linux drivers that use SME
in userspace. However, there are drivers that do not implement this
functionality. Extended wpa_supplicant to cover such cases as well.
The current implementation interprets this association error as a true
error, and will either add the BSS to the list of ignored BSSIDs, or
continue to try other BSSes. This can cause wpa_supplicant to back off
trying to reconnect for progressively longer intervals, depending on the
infrastructure's configured comeback timeout.
Allow wpa_supplicant to interpret the error, searching for the Timeout
Interval element in the (Re)Association Response frame and starting a
timer in the SME layer to re-associate after the timeout. This can be a
long delay (1-4 seconds in my experience), but it is likely much shorter
than bouncing between nearby BSSes.
This does not change behavior for drivers that implement association
comeback timer internally since they do not report the temporary
association rejection status code to user space.

BSS table is not updated when a non-P2P station runs a scan without P2P
IE in Probe Response frame, since that would remove P2P IE information.
However, this results also in not updating mandatory rates in Supported

This is causing connection failure since BSS table has 1 Mbps as

table when the BSS frequency is changed. This covers the most important

Overwriting of SSID for the hidden OWE BSS entry has some side effects:

- during (and after) association there will be multiple entries

Stop overwriting the SSID in an existing BSS entry based on OWE
transition mode information. Instead, depend on a new BSS entry getting
added for the hidden OWE BSS based on active scans for the SSID learned
from the open BSS. This would not have been sufficient for the initial

Since wpa_supplicant version 2.10 the extended capabilities MSCS and SCS

To avoid this issue the extended capabilities MSCS and SCS shall only be

avoid interoperability issues since these capabilities cannot be used
