80ddf5d995 FILS: Fix Key-Auth derivation for SK+PFS for authenticator side
The conditional gSTA and gAP (DH public keys) were not previously

Add support to set ignore assoc disallow to the driver so that the

3a46cf93d0 FT: Add support for wildcard R0KH/R1KH
Enable use of FT RRB without configuring each other AP locally. Instead,
broadcast messages are exchanged to discover APs within the local
network.

When an R0KH or R1KH is discovered, it is cached for one day.

When a station uses an invalid or offline r0kh_id, requests are always
broadcast. In order to avoid this, if r0kh does not reply, a temporary
blacklist entry is added to r0kh_list.

To avoid blocking a valid r0kh when a non-existing pmk_r0_name is
requested, r0kh is required to always reply using a NAK. Resend requests
a few times to ensure blacklisting does not happen due to small packet
loss.

To free newly created stations later, the r*kh_list start pointer in
conf needs to be updateable from wpa_auth_ft.c, where only wconf is
accessed.

eefe863015 FT RRB: Add msg replay and msg delay protection
This adds a counter and adds sequence numbering to FT RRB packets. The
sequence number is checked against r0kh/r1kh sequence number cache.

Special attention is needed in case the remote AP reboots and thus loses
its state. I prefer it to recover automatically even without synchronized
clocks. Therefore an identifier called dom is generated randomly along the
initial sequence number. If the dom transmitted does not match or the
sequence number is not in the range currently expected, the sender is asked
for a fresh confirmation of its currently used sequence numbers. The packet
that triggered this is cached and processed again later.

Additionally, in order to ensure freshness, the remote AP includes an
timestamp with its messages. It is then verified that the received
messages are indeed fresh by comparing it to the older timestamps
received and the time elapsed since then. Therefore FT_RRB_TIMESTAMP is
no longer needed.

This assigns new OUI 00:13:74 vendor-specific subtype 0x0001 subtypes:
4 (SEQ_REQ) and 5 (SEQ_RESP).

This breaks backward compatibility, i.e., hostapd needs to be updated
on all APs at the same time to allow FT to remain functional.

245fc96e5f FT: New RRB message format
Convert FT RRB into a new TLV based format. Use AES-SIV as AEAD cipher
to protect the messages.

This needs at least 32 byte long keys. These can be provided either
by a config file change or letting a KDF derive the 32 byte key used
from the 16 byte key given.

This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

50bd8e0a90 FT: Replace inter-AP protocol with use of OUI Extended Ethertype
Replace the previously used extension of IEEE 802.11 managed Ethertype
89-0d (originally added for Remote Request/Response in IEEE 802.11r)
with Ethertype 88-b7 (OUI Extended EtherType) for FT inter-AP
communication. The new design uses a more properly assigned identifier
for the messages.

This assigns the OUI 00:13:74 vendor-specific subtype 0x0001 for the new
hostapd AP-to-AP communication purposes. Subtypes 1 (PULL), 2 (RESP),
and 3 (PUSH) are also assigned in this commit for the R0KH-R1KH
protocol.

This breaks backward compatibility, i.e., hostapd needs to be updated on
all APs at the same time to allow FT to remain functional.

target value in get_mbo_transition_candidate() can be NULL if the driver
provided BSSID is not found in the wpa_supplicant BSS table. And later

9f894823fa PAE: Silence static analyzer warning about NULL pointer dereference
ieee802_1x_kay_move_live_peer() did not check
ieee802_1x_kay_get_potential_peer() result explicitly and a static
analyzer reported a warning about the possible NULL result. This cannot
really happen in practice since the only caller of
ieee802_1x_kay_move_live_peer() verifies that the specific peer entry is
available. Anyway, it is easy to silence the false warning by adding an
explicit check here and cover any other potential case if another caller
is added.
