OCE: Remove AP from driver disallow list with sufficient AP RSSI
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.

hostapd: Reject 40 MHz channel config if regulatory rules do not allow it
When regulatory rules are configured not to support 40 MHz channels on
the 2.4 GHz band, hostapd_is_usable_chans() still allowed 40 MHz
channels (i.e., 1-9) to be used with ht_capab=[HT40+][HT40-].
Looking into hostapd_is_usable_chans():
1) Validate primary channel using hostapd_is_usable_chan()
2) Try to pick a default secondary channel if hostapd_is_usable_chan()
3) Try to pick a valid secondary channel if both HT40+/HT40- set, and
further validate primary channel's allowed bandwidth mask.
4) Return channel not usable.
For example, for the 2.4 GHz channel 9 in Japan, its default secondary
channel is 13, which is valid per hostapd_is_usable_chan(), so step (2)
returns channel usable.
Add a more strict check to step (2) to clearly reject 40 MHz channel
configuration if regulatory rules do not allow the 40 MHz bandwidth,
which is similarly done in commit ce6d9ce15b07 ("hostapd: Add supported

Set last_eapol_matches_bssid=1 on a roam+auth indication from driver
Commit 3ab35a660364 ("Extend EAPOL frames processing workaround for
roaming cases") added a work around to address the issue of EAPOL frame
reception after reassociation replied to with an incorrect destination
address (the BSSID of the old AP). This is due to association events and
EAPOL RX events being reordered for the roaming cases with drivers that
perform BSS selection internally.
This mechanism relies on the fact that the driver always forwards the
EAPOL handshake to wpa_supplicant after the roaming (sets
last_eapol_matches_bssid during the EAPOL processing and resets on the
assoc/reassoc indication).
The above approach does not address the case where the driver does the
EAPOL handshake on the roam, indicating the authorized status to
wpa_supplicant but also forwards the EAPOL handshake to wpa_supplicant
for few other roam attempts. This is because the flag
last_eapol_matches_bssid is not set with the roam+authorized event from
the driver. Thus, the next reorder of roam and EAPOL RX events would
miss this workaround.
Address this by setting last_eapol_matches_bssid=1 on a roam+authorized
event from the driver.
