Commit 84751b98c1 ('WPS: Allow wildcard
UUID PIN to be used twice') relaxed the constraints on how many time a
wildcard PIN can be used to allow two attempts. However, it did this in
a way that could result in concurrent attempts resulting in the wildcard
PIN being invalidated even without the second attempt actually going as
far as trying to use the PIN and a WPS protocol run.
wildcard_uuid is a flag/counter set for wildcard PINs and it is
incremented whenever the PIN is retrieved by wps_registrar_get_pin().
Eventually it causes the wildcard PIN to be released, effectively
limiting the number of registration attempts with a wildcard PIN.
With the previous implementation, when the PIN is in use and locked
(PIN_LOCKED), it is not returned from wps_registrar_get_pin() but
wildcard_uuid is still incremented which can cause the PIN to be
released earlier and stations will have fewer registration attempts with
it. Fix this scenario by only incrementing wildcard_uuid if the PIN is
actually going to be returned and used.

ieee802_1x_kay_decode_mkpdu() calls ieee802_1x_mka_i_in_peerlist()
before body_len has been checked on all segments.
ieee802_1x_kay_decode_mkpdu() and ieee802_1x_mka_i_in_peerlist() might
continue and thus underflow left_len even if it finds left_len to small
(or before checking).
Additionally, ieee802_1x_mka_dump_peer_body() might perform out of bound
reads in this case.
Fix this by checking left_len and aborting if too small early.

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
with the changes proposed in
https://mentor.ieee.org/802.11/dcn/17/11-17-0906-04-000m-fils-fixes.docx
that add DHss into FILS-Key-Data (and PTK, in practice) derivation for
the PMKSA caching case so that a unique ICK, KEK, and TK are derived
even when using the same PMK.
Note: This is not backwards compatible, i.e., this breaks PMKSA caching
with FILS SK+PFS if only STA or AP side implementation is updated.

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
that change FILS cases to use HMAC-SHA-256 and HMAC-SHA-384 based on the
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.
