This commit introduces the following two attributes to
QCA_NL80211_VENDOR_SUBCMD_KEY_MGMT_ROAM_AUTH events:
QCA_WLAN_VENDOR_ATTR_ROAM_AUTH_STATUS - Indicates the status of
re-association requested by user space
QCA_WLAN_VENDOR_ATTR_ROAM_AUTH_RETAIN_CONNECTION - Indicates whether
the old association was maintained when a re-association
is requested by user space and that re-association attempt
fails (i.e., cannot connect to the requested BSS, but can
remain associated with the BSS with which the association was
in place when being requested to roam).

This commit defines an attribute
QCA_WLAN_VENDOR_ATTR_CONFIG_LISTEN_INTERVAL which allows the currently
used listen interval to be updated using
QCA_NL80211_VENDOR_SUBCMD_SET_WIFI_CONFIGURATION. This update applies
only during the association and is done without updating the AP about
the change.

Previously, only SHA1 hash -based server certificate matching was used,
but the OCSP response may use SHA256 instead of SHA1, so check the match
with both hash functions, if needed.

In some practical cases, it is useful to suppress joining to node in the

This needs to allow all 20 MHz channel numbers to be converted even
though the Annex E table lists only channel _center_ frequencies 50 and
114. Neighbor Report (see IEEE Std 802.11-2016, 9.4.2.37 Neighbor Report
element) uses Channel Number field with "last known primary channel of
the AP" which refers to the 20 MHz channel and not the channel center
frequency.

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.

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.

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.

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.

Commit 941caed980 ('MBO: Add MBO
ANQP-element processing on AP') changed the design by using the
rx_anqp_vendor_specific() function to process all ANQP vendor specific
elements. However, the caller for this was within ifdef CONFIG_HS20
block. Fix this by calling the function even in CONFIG_HS20=y is not
included in the build. This fixes CONFIG_MBO=y builds without
CONFIG_HS20=y.

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.
