438a27b369 Do not derive SAE PT if the network profile does not include SAE
wpa_s_setup_sae_pt() derived SAE PT even when the configured key
management options did not include SAE if the global sae_pwe
configuration parameter had been changed to enable H2E. This adds
unnecessary extra delay, so derive PT only if SAE is actually enabled in
the network profile.

Instead of practically ignoring an odd octet at the end of the element,

dab7549d68 SSID protection in 4-way handshake on STA
Add support for SSID protection in 4-way handshake based on the
mechanism added in IEEE 802.11REVme/D6.0. This is a mitigation against
CVE-2023-52424 (a.k.a. the SSID Confusion Attack).

This functionality is disabled by default and can be enabled with
ssid_protection=1 in the network profile. Once there has been more
testing of this to confirm there is no significant interoperability
issues, the goal is to be able to change this to be enabled by default.

9a022cdc70 STA: Update scan results when BSS entry with current SSID is not found
wpa_supplicant might use a wrong BSS entry with the SSID different from
the current SSID of the current BSS while processing a roam event from
the driver when wpa_supplicant has a stale BSS entry with the old SSID
and the driver roams to the same BSS after it is restarted with a new
SSID.

To avoid this, update scan results from the driver when a BSS entry is
not found with the current SSID and try to fetch the BSS entry again
with the current SSID after this.

Also, with this change wpa_supplicant_get_new_bss() itself will update
the BSS table and search for the current BSS entry if it is not found in
the BSS table. So, remove the BSS table update and search logic from the
callers of wpa_supplicant_get_new_bss().

ed56dfc339 P2P: Fix fast IP address allocation for invitation of a persistent group
Allocate static IPv4 address in EAPOL frames during 4-way handshake
instead of DHCP when using P2P invitation. wpa_s->current_bss needs to
be set for the P2P specific IP address assignment mechanism to be used
in wpa_supplicant_rsn_supp_set_config(). This worked for the initial P2P
connection, but not for some cases reinvoking a persistent group.

Since there is only one AP (P2P GO) in the P2P client case, the
conditions added in commit 4d3be9cdd1 ("Postpone updating of
wpa_s->current_bss till association event") are not needed and the
easiest approach for this is to allow current_bss to be set for
p2p_in_invitation cases. If the GO P2P Interface Address (BSSID) could
be determined for all the related cases, this could be addressed a bit
more cleanly by setting the go_bssid argument for
wpas_start_p2p_client(), but that can be left as a possible future step.

8d0bd7f9c8 Update BSS entry on roaming only for actual BSS frequency change
Commit 117e812d06 ("Update BSS table entry if roaming event indicates
frequency change") added wpa_supplicant BSS table update based on the
latest driver scan results whenever processing an association event that
results in the current operating channel changing. While that is needed
to cover the case where an AP changes its own operating channel (and
that is noticed as a roam or new connection instead of a channel switch
event), this should not really be needed for cases where the
wpa_supplicant entry for the new BSS is already up to date.

Skip the full BSS table update on association event if the event is for
a roaming case to a different BSS and the BSS entry for the target is
already available and for the current operating channel. This avoids
undesired latency when processing the association event.

that use two nonadjacent frequency segments.

operating class design using the Operating Class Duple sequence field of
the Supported Operating Classes element instead of listing the operating
classes that have the 80+ behavior limit set indication in Table E-4

e508c070c4 WNM: Keep BTM information until connection completes
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.

Which one it refers to depends on whether wnm_link_removal is set.

e164943f43 WNM: Wait for BTM response TX status before roaming
When accepting a BSS transition request there is a race between
sending the response and roaming to the target AP. As a result,
the response may not be sent because the station deauthenticated
from the AP before the response was actually sent.

To make sure the BSS transition response is sent, start roaming only
after the TX status is received for the BSS transition response.

20ed289a78 WNM: Clean up old scan data processing
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.

b18d957593 P2P: Disable pri/sec channel switch for GO with forced frequency
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.

33179cd291 SME: Handle PMF association comeback when not handled in driver
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.
