Driver/firmware does roam scan when it finds the need to roam to a
different BSS. Add a QCA vendor event to indicate such roam scan events
from driver/firmware to user space.
Please note that some drivers may not send these events in few cases,
e.g., if the host processor is sleeping when this event is generated in
firmware to avoid undesired wakeups.
OWE: Do not try to enable PMF for non-RSN associations
Explicitly set the PMF configuration to 0 (NO_MGMT_FRAME_PROTECTION) for
non-RSN associations. This specifically helps with OWE transition mode
when the network block is configured with PMF set to required, but the
BSS selected is in open mode. There is no point to try to enable PMF for
such an association.
This fixes issues with drivers that use the NL80211_ATTR_USE_MFP
attribute to set expectations for PMF use. The combination of non-RSN
connection with claimed requirement for PMF (NL80211_MFP_REQUIRED) could
cause such drivers to reject the connection in OWE transition mode.
This verifies that wpa_supplicant and hostapd behave consistently with
PMKSA caching when Suite B AKMs end up deriving a new PMKID from each
4-way handshake.
RSN: Do not replace existing Suite B PMKSA on 4-way handshake
PMKID derivation with the Suite B AKMs is a special case compared to
other AKMs since that derivation uses KCK instead of PMK as an input.
This means that the PMKSA cache entry can be added only after KCK has
been derived during 4-way handshake. This also means that PMKID would
change every time 4-way handshake is repeated even when maintaining the
same PMK (i.e., during PTK rekeying and new associations even if they
use PMKSA caching).
wpa_supplicant was previously replacing the PMKSA cache entry whenever a
new PMKID was derived. This did not match hostapd expectations on the AP
side since hostapd did not update the PMKSA cache entry after it was
created. Consequently, PMKSA caching could be used only once (assuming
no PTK rekeying happened before that). Fix this by making wpa_supplicant
behave consistently with hostapd, i.e., by adding the Suite B PMKSA
cache entries with the PMKID from the very first 4-way handshake
following PMK derivation and then not updating the PMKID.
IEEE Std 802.11-2016 is somewhat vague in this area and it seems to
allow both cases to be used (initial PMKID or any consecutive PMKID
derived from the same PMK). While both cases could be supported that
would result in significantly more complex implementation and need to
store multiple PMKID values. It looks better to clarify the standard to
explicitly note that only the first PMKID derived after PMK derivation
is used (i.e., match the existing hostapd implementation).
This was used during initial EST development time testing, but the same
information is available in the debug log and since this separate file
is deleted automatically, just remove its generation completely to
simplify implementation.
This is a regression test case for a memory leak on DPP_CONFIGURATOR_ADD
error path in dpp_keygen_configurator() when an unsupported curve is
specified.
eap_proxy: Fix memory leaks when using eap_peer_erp_init()
The external session_id and emsk from eap_proxy_get_eap_session_id() and
eap_proxy_get_emsk() need to be freed consistently in all code paths
within eap_peer_erp_init() and outside it in the case ERP is not
initialized.
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

design that was used with OpenSSL 1.1.1 and BoringSSL.

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

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

where transition mode is used.
RADIUS server: Add testing support for authentication result

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

mismatch between the ERP server and peer using full EAP authentication.
Address this by trying to use full (non-FILS) authentication when trying
to connect to an AP using the same ERP realm with FILS-enabled network
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.
