The driver might delete the STA node details on receiving external auth
status. In SAE authentication failure case on the AP, an Authentication
frame with a failure status is sent to the driver after sending the
external auth status. Authentication frame transmission didn't have a
dependency with STA node details earlier, but with MLO, Authentication
frames should be transmitted using the link address for a given MLD MAC
address by the supplicant. Since MLD to link address translation is done
by the driver, the STA node details are required to transmit the
Authentication frame. Hence, send external auth status to the driver
after sending the Authentication frame.
SAE external auth was introduced in commit 4ffb0fefe4 ("hostapd:
Support external authentication offload in AP mode"), which requires the
change in order of sending Authentication frame and auth status in case
of failure when using MLO.

This provides an implicitly protected (SNonce is used as an input to PTK
derivation) mechanism for a STA to indicate support for RSN overriding
in a manner that does not cause interopability issues with deployed APs.
In addition, update sm->SNonce on the Authenticator only based on
message 2/4 since that is the only EAPOL-Key message that is defined to
provide the actual SNonce value. While clearing of this internal buffer
on message 4/4 might not cause issues, it is better to keep the actual
SNonce value here since the SNonce cookie can be used at a later point
in the sequence.

wpa_supplicant select_network() relies on fast_associate to reuse old
scan results. However, this approach does not apply in some cases in
Android:
1 - If the selected network is hidden, and the SSID is in Chinese,
Android switches between fallback SSIDs, necessitating a new scan for
switching between different hidden SSIDs.
2 - Similarly, if the selected SSID is OWE (Opportunistic Wireless
Encryption), and the OWE SSID bands have been changed, select_network()
requires a fresh scan to discover hidden OWE SSIDs.
To address these, enhance select_network() to trigger new scans instead
of relying on fast_associate. This improves network selection behavior
in Android.

Add a new QCA command QCA_NL80211_VENDOR_SUBCMD_USD and related
attributes to support Unsynchronized Service Discovery (USD).
Device in active subscriber role sends SDF frames with service
information to find devices that advertise or publish the required
services. Device address, operation type, instance id, service_id,
channel info, service specific info, element container attribute, and
timeout are sent to the driver to initiate USD publish or USD subscribe
operation. The driver sends QCA_NL80211_VENDOR_SUBCMD_USD event with
instance_id and the USD operation status. QCA_NL80211_VENDOR_SUBCMD_USD
is also used to update publish operation and to cancel the publish or
subscribe operation for a service. It also allows all the operations to

In the hostapd_cleanup_driver() function, the NULL check for the driver
private data (drv_priv) is located within the CONFIG_IEEE80211BE feature
flag. As a result, on platforms where CONFIG_IEEE80211BE is not defined,
driver->hapd_deinit(drv_priv) is called with drv_priv set to NULL. This
leads to a null pointer exception in wpa_driver_nl80211_deinit().
To address this issue, move the NULL check for drv_priv outside the
CONFIG_IEEE80211BE build flag. This ensures that the check is performed
regardless of the value of CONFIG_IEEE80211BE, preventing the NULL
pointer exception.
