For hidden GBK encoding of a Chinese SSID, both the UTF-8 and GBK
encoding profiles are added into wpa_supplicant to make sure the
connection succeeds. In this situation, wpa_supplicant_select_network()
will not be called so current_ssid is NULL when association begins.
Android monitors the WPA_EVENT_STATE_CHANGE event to get the SSID and
BSSID. When connecting to a Chinese SSID, in case of association
rejection happens, Android will report null SSID to OEM APP because
current_ssid is updated after wpa_supplicant_set_state(wpa_s,
WPA_ASSOCIATING), which may cause confusion.
Fix this by setting the current_ssid before changing state to

Some distros carry patches to specify driver fallback, but only in
specific conditions (e.g. the systemd service definition[1]). This leaves
other wpa_supplicant instances needing to define fallback themselves,
which leads to places where wpa_supplicant thinks it can't find a
driver[2]. Instead, when -D is not specified, have wpa_supplicant try
all the drivers it was built with in an attempt to find a working one
instead of just giving up if the first doesn't work.

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.

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.

wpa_supplicant_ctrl_iface_deinit() was executed only if the
per-interface control interface initialization had been completed. This
is not the case if driver initialization fails and that could result in
leaving behind references to the freed wpa_s instance in a corner case
where control interface messages ended up getting queued.
Fix this by calling wpa_supplicant_ctrl_iface_deinit() in all cases to
cancel the potential eloop timeout for wpas_ctrl_msg_queue_timeout with
the reference to the wpa_s pointer. In addition, flush any pending
message from the global queue for this interface since such a message
cannot be of use after this and there is no need to leave them in the
queue until the global control interface gets deinitialized.

An EAPOL frame may be pending when wpa_supplicant requests to
deauthenticate. At this stage the EAP SM cache is already cleaned by
calling eapol_sm_invalidate_cached_session(). Since at this stage the
wpa_supplicant's state is still set to associated, the EAPOL frame is
processed and results in a crash due to NULL dereference.
This wasn't seen previously as nl80211 wouldn't process the
