90e478aa0a DPP2: Use the PFS fallback if multiple key_mgmt values are enabled
Previously this fallback from PFS enabled to disabled (and back to
enabled) was used only if the local network profile used key_mgmt=DPP,
i.e., did not enable another other AKM. That leaves out some valid cases
since the local network profile could actually enable both DPP and SAE.
Extend this check to accept cases DPP AKM is enabled and it was selected
for the connection even if there other enabled AKMs.

af8ab3208d MSCS: Parse result of MSCS setup in (Re)Association Response frames
Add support to parse the (Re)Association Response frames to check if the
AP has accepted/declined the MSCS request in response to the
corresponding (Re)Association Request frame. AP indicates the result by
setting it in the optional MSCS Status subelement of MSCS Descriptor
element in (Re)Association Response frame.

This MSCS Status subelement is defined in the process of being added

fcef598ea2 Do not try to connect with zero-length SSID
It was possible to find a BSS to local network profile match for a BSS
entry that has no known SSID when going through some of the SSID
wildcard cases. At leas the OWE transition mode case without BSSID match
could result in hitting this. Zero-length SSID (i.e., wildcard SSID) is
not valid in (Re)Association Request frame, so such an association will
fail. Skip such a BSS to avoid known-to-be-failing association attempts.

5058f771d9 DPP2: Allow station to require or not allow PFS
The new wpa_supplicant network profile parameter dpp_pfs can be used to
specify how PFS is applied to associations. The default behavior
(dpp_pfs=0) remains same as it was previously, i.e., try to use PFS if
the AP supports it. PFS use can now be required (dpp_pfs=1) or disabled
(dpp_pfs=2).

This is also working around an interoperability issue of DPP R2 STA with
certain hostapd builds that included both OWE and DPP functionality.
That issue was introduced by commit 09368515d1 ("OWE: Process
Diffie-Hellman Parameter element in AP mode") and removed by commit
16a4e931f0 ("OWE: Allow Diffie-Hellman Parameter element to be
included with DPP"). hostapd builds between those two commits would
reject DPP association attempt with PFS. The new wpa_supplicant default
(dpp_pfs=0) behavior is to automatically try to connect again with PFS
disabled if that happens.

3c73811507 OWE: Mark BSS for transition mode based on active OWE network profiles
It is possible for the hidden OWE BSS to be found based on SSID-specific
scan (e.g., from the special OWE scan mechanism). In that sequence, the
previously used learning of OWE BSS was skipped since the SSID was
already present in the BSS entry. This could result in not being able to
find a matching BSS entry for the OWE BSS in transition mode.

Fix this by adding the BSS flag for transition mode based on SSID
matching against currently enabled OWE network profiles in addition to
the previous mechanism.

ecb5219d8c OWE: Avoid incorrect profile update in transition mode
The "unexpected" change of SSID between the current network profile
(which uses the SSID from the open BSS in OWE transition mode) and the
association with the OWE BSS (which uses a random, hidden SSID) resulted
in wpa_supplicant incorrectly determining that this was a
driver-initiated BSS selection ("Driver-initiated BSS selection changed
the SSID to <the random SSID from OWE BSS>" in debug log).

This ended up with updating security parameters based on the network
profile inwpa_supplicant_set_suites() instead of using the already
discovered information from scan results. In particular, this cleared
the RSN supplicant state machine information of AP RSNE and resulted in
having to fetch the scan results for the current BSS when processing
EAPOL-Key msg 3/4.

Fix this by recognizing the special case for OWE transition mode where
the SSID for the associated AP does not actually match the SSID in the
network profile.

Do not set connection_vht when the operating band is 2.4 GHz. This

a2c1bebd43 Improve roaming logic
Currently, wpa_supplicant may roam too aggressively; the need_to_roam()
function will return early with a roaming decision if the difference in
signal level or throughput between the current and selected APs is
"sufficiently large." In particular, if the selected AP's estimated
throughput is more than 5k greater than the current AP's estimated
throughput, wpa_supplicant will decide to roam. Otherwise, if the
selected AP's signal level is less than the current AP's signal level,
or the selected AP's estimated throughput is at least 5k less than the
current AP's estimated throughput, wpa_supplicant will skip the roam.
These decisions are based only on one factor and can lead to poor
roaming choices (e.g., a roam should not happen if the selected AP's
estimated throughput meets the threshold but the current signal and
throughput are already good, whereas a roam should happen if the signal
is slightly worse but the estimated throughput is significantly better).

This change standardizes the roaming heuristic for signal strength
difference requirements and will hopefully improve user experience. The
change can be summarized as follows: based on the current signal level,
a certain roaming difficulty is assigned. Based on the selected AP's
estimated throughput relative to the current AP's estimated throughput,
the difficulty is adjusted up or down. If the difference in signal level
meets the threshold, a roam happens.

The hard-coded values were selected purely based on the previous version
of this function. They may eventually need to be fine-tuned for optimal
performance.

f4f7600adf Use signal_poll noise information for roaming, if available
Using average signal strength from the driver and hardcoded noise floor
does not look like an ideal design since there can be significant
differences in the driver-reported noise floor values. Furthermore, even
though the current noise floor is a snapshot from the driver, it is
common for drivers to use a noise floor value from a longer calibration
step and that should not prevent the driver provided value from being
used. This makes the comparisons of the signal strengths between the
current AP (signal_poll) and other APs (scan) more accurate.

As an example, test runs in home environment showed 5 dB difference
between the driver reported noise floor and the hardcoded value and this
could result in significant differences in estimated throughput
calculation.

7e7b23e229 Update throughput estimate for the current BSS based on signal poll
We saw that on certain platforms in certain places we keep switching
between two APs and eventually get the same RSSI. Debugging showed that
we have a very big difference between the two antennas.

Ant A can hear AP A very well (-60) but AP B very bad (-80)
Ant B can hear AP B very well (-60) but AP A very bad (-80)

When the device associates to AP A, it'll learn to use Ant A. If the
device uses one single antenna to receive the scan results, it may hear
the AP it is currently associated to on the second antenna and get bad
results. Because of that, the wpa_supplicant will roam to the other AP
and the same scenario will repeat itself:

Association to AP A (Ant A reports -60).
Scan on Ant A: AP A: -60, AP B: -80
Scan on Ant B: AP A: -80, AP A: -60 ==> ROAM.

Association to AP B (Ant B reports -60)
Scan on Ant A: AP A: -60, AP B: -80 ==> ROAM

Etc...

Improve this by querying the signal level of the current AP using
drv_signal_poll() instead of relying on the signal level that we get
from the scan results. Also update the throughput estimate based on the
likely more accurate values for the current association.

e3c476bd8c SAE H2E: Fix RSNXE override in EAPOL-Key msg 2/4 for testing purposes
The previous implementation missed the case where EAPOL-Key frame may be
reported as having been received before the association event is
processed. This would have resulted in not using the RSNXE override for
EAPOL-Key msg 2/4 when the pending EAPOL-Key frame gets processed
immediately after processing the association event. Fix this by moving
the override case to be handled before that.

405946d76a SAE: Testing option to ignore H2E requirement mismatch
"SET ignore_sae_h2e_only 1" can now be used to configurate
wpa_supplicant to a test mode where it ignores AP's H2E-required
advertisement and try to connect with hunt-and-pecking loop instead.
This is used only for testing AP behavior with unexpected STA behavior.
