Not all code paths for management frame RX reporting delivered the
correct frequency for offchannel RX cases. This is needed mainly for
Public Action frame processing in some special cases where AP is
operating, but an exchange is done on a non-operational channel. For
example, DPP Initiator role may need to do this.

Set Sc to 2^16-1 when moving to Accepted state per IEEE Std 802.11-2016,

This implements the behavior described in IEEE Std 802.11-2016,

If fils_decrypt_assoc() were to fail on the AP side, the previous
implementation could have continued through the response generation
using left = -1. That could have resulted in unexpected processing if
this value were to be used as the length of the remaining (unencrypted)
IEs. Fix this by not updating left in the failure case.

The previously used WLAN_REASON_MICHAEL_MIC_FAILURE (14) value as a
response to Authentication frame or (Re)Association Request frame is not
correct since the resp value is encoded in the Status Code (not Reason
Code) field. Status Code 14 is WLAN_STATUS_UNKNOWN_AUTH_TRANSACTION
which is really what this value would have meant in the response frames.
There is no Michael MIC failure status code, so have to use the generic
"Unspecified failure" (1) reason code for these cases.

The previous implementation ended up starting a new EAPOL-Key 4-way
handshake if the STA were to attempt to perform another association.
This resulted in immediate disconnection since the PTK was not ready for
configuring FILS TK at the point when EAPOL-Key msg 1/4 is sent out.
This is better than alloing the association to continue with the same TK
reconfigured, but not really ideal.
Address this potential sequence by not starting a new 4-way handshake on
the additional association attempt. Instead, allow the association to
complete, but do so without reconfiguring the TK to avoid potential
issues with PN reuse with the same TK.

Do not reinstall TK to the driver during Reassociation Response frame
processing if the first attempt of setting the TK succeeded. This avoids
issues related to clearing the TX/RX PN that could result in reusing
same PN values for transmitted frames (e.g., due to CCM nonce reuse and
also hitting replay protection on the receiver) and accepting replayed
frames on RX side.
This issue was introduced by the commit
0e84c25434 ('FT: Fix PTK configuration in
authenticator') which allowed wpa_ft_install_ptk() to be called multiple
times with the same PTK. While the second configuration attempt is
needed with some drivers, it must be done only if the first attempt
failed.

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.

WNM. This allows binary size to be reduced for builds that require

hostapd processes a received 20/40 BSS Coexistence management frame, but
if no separate callbacks are registered for handling Public Action
frames it eventually sends a reply with MSB of category code set to 1
thinking that the received frame is an invalid frame. This could happen
based on whether hostapd was built and enabled with functionality using
the callback functions.
Fix this by explicitly returning 1 from the function when the 20/40 BSS
Coexistence Management frame is processed.

Relational operators (==) have higher precedence than the ternary
conditional in C. The last_subtype check for association/reassociation
was broken due to incorrect assumption about the precedence. Fix this by
adding parenthesis around the ternary conditional.
The previous implementation worked for Association Request frames by
accident since WLAN_FC_STYPE_ASSOC_REQ happens to have value 0 and when
the last receive frame was an Association Request frame, the
sta->last_subtype == reassoc check was true and non-zero
WLAN_FC_STYPE_REASSOC_REQ was interpreted as true. However, this was
broken for Reassociation Request frame. reassoc == 1 in that case could
have matched received Association Response frame (subtype == 1), but
those are not received in AP mode and as such, this did not break other
behavior apart from not being able to drop duplicated Reassociation
Request frames.
