DPP: Flush PMKSA if an assoc reject without timeout is received
Flush the PMKSA upon receiving assoc reject event without timeout
in the event data, to avoid trying the subsequent connections
with the old PMKID. Do not flush PMKSA if assoc reject is
received with timeout as it is generated internally from the
driver without reaching the AP.
DPP: Fix test functionality for invalid keys with OpenSSL 1.1.0
It looks like at least OpenSSL 1.1.0i includes the extra checks in
EC_POINT_set_affine_coordinates_GFp() that break the previously used
mechanism for generating invalid keys. Fix this by using the alternative
design that was used with OpenSSL 1.1.1 and BoringSSL.
It was possible for the wait loop to exit early due to the $row[0] == 1
check returning false if the database value was not yet set. Fix this by
updated the $waiting default value only if the database actually has a
value for this field.
HS 2.0: Allow OSU SSID selection to be enforced for testing purposes
This allows hs20-osu-client to be requested to select a specific OSU

HS 2.0: Use shared SSID (if available) for OSU by default
When the AP is detected to have single BSS shared for RSN and OSEN, use
that BSS for OSU by default instead of the one based on the OSU_SSID in
the OSU Providers list.
HS 2.0: Add alternative OSU_SSID into providers info file

FILS: Fix FILS connect failures after ERP key invalidation
If the RADIUS authentication server dropped the cached ERP keys for any
reason, FILS authentication attempts with ERP fails and the previous
wpa_supplicant implementation ended up trying to use the same keys for
all consecutive attempts as well. This did not allow recovery from state
mismatch between the ERP server and peer using full EAP authentication.
Address this by trying to use full (non-FILS) authentication when trying

profile if the previous authentication attempt had failed. This allows
new ERP keys to be established and FILS authentication to be used again
for the consecutive connections.

never canceled; once it executes, the interface is gone, most likely
