Inclusion of common/dpp.h into hostapd/main.c brought in an undesired
unconditional dependency on OpenSSL header files even for builds where
DPP is not enabled. Fix this by making the dpp.h contents, and in
particular the inclusion of openssl/x509.h, conditional on CONFIG_DPP.

The rules defining which DH groups are suitable for SAE use were
accepted into IEEE 802.11 REVmd based on this document:
https://mentor.ieee.org/802.11/dcn/19/11-19-0387-02-000m-addressing-some-sae-comments.docx
Enforce those rules in production builds of wpa_supplicant and hostapd.
CONFIG_TESTING_OPTIONS=y builds can still be used to select any o the
implemented groups to maintain testing coverage.

Reduce testing dependency on the unsuitable groups so that a test case
against a production build would not fail the test case unnecessarily.
This is in preparation of making production builds
(CONFIG_TESTING_OPTIONS not defined) of wpa_supplicant hostapd disable
all DH groups that have been indicated as being unsuitable.

Previously, PMKSA cache entries were search for AKM=SAE and that did not

When connected using FT-SAE key mgmt, use PMK from PMKSA cache as XXKey

XXKey when using SAE PMKSA caching for the initial mobility domain
association.

In the case of the driver not supporting full AP mode STA state (i.e.,
not adding a STA entry before association), the QoS parameters are not
allowed to be modified when going through (re)association exchange for a
STA entry that has not been removed from the kernel. cfg80211 would
reject such command to update STA flags, so do not add the WMM parameter
in this case.

Ethernet frames have minimum length of 64 octets and shorter frames may
end up getting arbitrary padding in the end. This would result in the
FT/RRB receiver rejecting the frame as an incorrectly protected one.
Work around this by padding the message so that it is never shorter than
the minimum Ethernet frame.
Unfortunately, this padding is apparently not enough with all Ethernet
devices and it is still possible to see extra two octet padding at the
end of the message even if larger frames are used (e.g., showed up with
128 byte frames). For now, work around this by trying to do AES-SIV
decryption with two octets shorter frame (ignore last two octets) if the
first attempt fails.

If a network profile has both SAE and FT-SAE enabled, SAE was previously
picked (and used incorrectly as explained in the previous commit). This
is not ideal since use of FT protocol can speed up roaming within in

SAE if both are enabled.

Do not try to initialize FT reassociation if the selected AKM is for SAE
instead of FT-SAE when both of these are enabled in a network profile.
This fixes an issue with MDE being included in an (Re)Association
Request frame even when using a non-FT AKM (which is something that
results in hostapd rejecting the association).

The memcpy calls added for exposing the PMK from wpa_auth module could
end up trying to copy the same memory buffer on top of itself.
Overlapping memory areas are not allowed with memcpy, so this could

on the updated value actually coming from somewhere else.

This code was after the FILS handling that would have encrypted the
frame. While FILS and OWE are never used together, the OWE handling
should really be before the FILS handling since no IEs can be added
after the FILS encryption step. In addition, the Diffie-Hellman
Parameter element is not a Vendor Specific element, so it should be
before some of the Vendor Specific elements even though it is not
defined in IEEE 802.11.
