Vendor flags for 11ax channel property flags for use with external ACS
Add 802.11ax channel property flags for use with external ACS (QCA
vendor command). Use the remaining available bits in
qca_wlan_vendor_channel_prop_flags for the first few 11ax flags. Then
add qca_wlan_vendor_channel_prop_flags_2 as a continuation of
qca_wlan_vendor_channel_prop_flags and add the remaining 11ax flags
there. Note that qca_wlan_vendor_channel_prop_flags_ext is not used

it is meant for holding additional control information related to
features such as DFS, CSA, etc.

The FILS features on STA needs to be disabled for testing purposes to

TDLS: Update the comments related to TPK derivation
Update these comments based on IEEE Std 802.11-2016 to get rid of the
already resolved TODO comment regarding duplicated N_KEY use. The
implementation does not need any changes since it was already following
the fixed version in the current standard.
There was a race condition on the sequence where iface.AbortScan() is
immediately followed by iface.Scan(). If the driver event
(NL80211_CMD_SCAN_ABORTED) arrived after the following new scan request,
the D-Bus operation failed. This is not what this test case is trying to
check, so wait for an indication of the previous scan having terminated
properly before issuing the next scan.
FILS: Check req_ies for NULL pointer in hostapd_notif_assoc()
Add checking for NULL req_ies when FILS processing a driver ASSOC event
in hostapd_notif_assoc(). This was already done in number of old code
paths, but the newer FILS path did not handle this. Though, it is
unlikely that this code path would be reachable in practice since this
is all within sta->auth_alg == WLAN_AUTH_FILS_* check.
OpenSSL: Force RSA 3072-bit DH prime size limit for Suite B
Reject a DHE handshake if the server uses a DH prime that does not have
sufficient length to meet the Suite B 192-bit level requirement (<= 3k

OpenSSL: Add option to disable ECDHE with Suite B RSA
The hostapd.conf tls_flags=[SUITEB-NO-ECDH] and wpa_supplicant network
profile phase1="tls_suiteb_no_ecdh=1" can now be used to configure Suite
B RSA constraints with ECDHE disabled. This is mainly to allow

Reject a peer certificate chain if it includes an RSA public key that

FILS: Add DHss into FILS-Key-Data derivation when using FILS SK+PFS
This part is missing from IEEE Std 802.11ai-2016, but the lack of DHss
here means there would not be proper PFS for the case where PMKSA
caching is used with FILS SK+PFS authentication. This was not really the
intent of the FILS design and that issue was fixed during REVmd work

the PMKSA caching case so that a unique ICK, KEK, and TK are derived

FILS: Update PMKID derivation rules for ERP key hierarchy establishment
IEEE Std 802.11ai-2016 had missed a change in the Pairwise key hierarchy
clause (12.7.1.3 in IEEE Std 802.11-2016) and due to that, the previous
implementation ended up using HMAC-SHA-1 -based PMKID derivation. This
was not really the intent of the FILS design and that issue was fixed
during REVmd work with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx

negotiated AKM.
Update the implementation to match the new design. This changes the
rsn_pmkid() function to take in the more generic AKMP identifier instead
of a boolean identifying whether SHA256 is used.
Note: This is not backwards compatible, i.e., this breaks PMKSA caching
based on the initial ERP key hierarchy setup if only STA or AP side
implementation is updated. PMKSA caching based on FILS authentication
exchange is not impacted by this, though.

Fix RSN pre-authentication regression with pre-connection scan results
The introduction of radio works and a delayed callback to complete
association/connection requests ended up breaking RSN pre-authentication
candidate list generation for the case of pre-connection scan results.
Previously, wpa_supplicant_associate() set the RSN state machine
configuration before returning and the calls to
wpa_supplicant_rsn_preauth_scan_results() immediately after this
function call were working fine. However, with the radio work callback,
the RSN state machine configuration started to happen only in that
callback which would be called soon after this code path has completed.
This resulted in the RSN state machine not knowing the selected SSID and
as such, rejecting all pre-authentication candidates.
Fix this by setting the RSN state machine configuration from
wpa_supplicant_associate() so that the existing callers of
wpa_supplicant_rsn_preauth_scan_results() can be used as-is to add
candidates for pre-authentication.
