Update PMKSA cache when interface is disabled and then enabled based on

address, the PMKSA cache entries are valid and hence update the PMKSA
cache entries to the driver. If the new MAC address is not same as the
previous MAC address, the PMKSA cache entries will not be valid anymore
and hence delete the PMKSA cache entries.

While creating a cloned PMKSA entry for OKC both expiration and
reauth_time values are set to maximum values, but later only the
expiration time is copied from the old PMKSA entry to the new PMKSA
entry. Due to this there is a possibility of reauth_time becoming
greater than expiration time in some cloned entries. To avoid this copy
reauth_time also to the cloned entry.
Also, add check to reject control interface commands with reauth time
greater than expiration time.

MHz bandwidth to be used for autonomous GO when using offloaded DFS.

- Enhanced behavior: AP starts on channel 100 using 80 MHz with

P2P connections in the 6 GHz band use SAE authentication algorithm after
getting credentials with WPS connection. During WPS connection as it
doesn't use SAE, SAE PT is not derived. After getting SAE credentials,
the STA connects to the same SSID using SAE auth algorithm. Earlier, SAE
H2E PT was not derived while connecting to the same SSID to which the
STA is connected last time. Due to this, the P2P group formation fails
for 6 GHz channels when H2E is enabled as the PT will not be setup by
the P2P client before proceeding to the SAE authentication. Same could
happen with infrastructure WPS when wps_cred_add_sae=1 is used.
Set up the SAE H2E PT while connecting to the same SSID again also to
make sure that the H2E PT is set up in the STA to derive the PWE for
successful SAE authentication. The PT derivation will be skipped in
wpa_s_setup_sae_pt() if PT is already available for that SSID.

External applications can store PMKSA entries persistently and
reconfigure them to wpa_supplicant after restart. This can result in
wpa_supplicant having a PMKSA for FILS authentication without having
matching ERP keys for it which would prevent the previously added
mechanism for dropping FILS PMKSA entries to recover from rejected
association attempts.
Fix this by clearing PMKSA entries configured by external applications
upon FILS connection failure even when ERP keys are not available.
Signed-off-by: Veerendranath Jakkam <vjakkam@codeaurora.org>
wpa_supplicant generates both a PMKSA cache entry and ERP keys upon
successful FILS connection and uses FILS authentication algorithm for
subsequent connections when either ERP keys or a PMKSA cache entry is
available.
In some cases, like AP/RADIUS server restart, both ERP keys and PMKSA
becomes invalid. But currently when an AP rejects an association,
wpa_supplicant marks only ERP keys as failed but not clearing PMKSA.
Since PMKSA is not cleared, consecutive connection attempts are still
happening with FILS authentication algorithm and connection attempts are
failing with the same association rejection again instead of trying to
recover from the state mismatch by deriving a new ERP key hierarchy.
Clear PMKSA entries as well on association rejection from an AP to allow
the following connection attempt to go with open authentication to
re-establish a valid ERP key hierarchy. Also, since clearing PMKSA
entries on unprotected (Re)Association Response frames could allow DoS
attack (reduce usability of PMKSA caching), clear PMKSA entries only
when ERP keys exists.

When a STA makes an association request that is rejected by an OCE AP
due to the RSSI being insufficient, the AP is added to the driver
disallow list by wpa_set_driver_tmp_disallow_list().
Once the AP increases TX power which makes the AP RSSI higher than
Association Rejection RSSI threshold, the AP is supposed to be removed
from the driver disallow list but that was not the case.
wpa_is_bss_tmp_disallowed() is called in the scan result handler, so it
is the best place to put the logic of removing the AP from the driver
disallow list with sufficient AP RSSI.
This is needed with drivers that use the temporarily disallowed BSS list
(which is currently supported only with a QCA vendor command). The
wpa_supplicant internal functionality was already taking care of this
with the wpa_is_bss_tmp_disallowed() return value even for cases where
the entry remaining in the list.

APs in 6 GHz operating with LPI/VLP rules will have significantly lower
SNR values compared to 2.4/5 GHz band APs. Earlier, the estimated
throughputs were used for comparison only when the delta of SNRs between
both the APs was not greater than 7 and as a result for comparing 6 GHz
APs with 2.4/5 GHz APs, estimated throughputs were not getting used.
The estimated throughput calculations takes SNR value also into
consideration, hence remove RSSI delta check if any of the APs are from
the 6 GHz band. This change is limited to the 6 GHz band only in order
