As FCC DFS requirement does not explicitly mention about the validity of
the (pre-)CAC when channel is switched, it is safe to assume that the
pre-CAC result will not be valid once the CAC completed channel is
switched or radar detection is not active on the (CAC completed) channel
within a time period which is allowed (10 seconds - channel switch time)
as per FCC DFS requirement.
Use the new driver event to allow the driver to notify expiry of the CAC
result on a channel. Move the DFS state of the channel to 'usable' when
processing pre-CAC expired event. This means any future operation on
that channel will require a new CAC to be completed. This event is
applicable only when DFS is not offloaded to the kernel driver.

Previously the peer operating channel preference was accepted if the
indicated frequency was listed in the local preference list from the
driver. This was assuming that the driver included only channels that
are currently enabled for GO operation. Since that might not be the
case, filter the local preference list by doing an explicit validation
of the indicated channels for P2P support.
This moves the similar validation steps from two other code paths in
p2p_check_pref_chan_recv() and p2p_check_pref_chan_no_recv() into a
common filtering step in p2p_check_pref_chan() for all three cases.

The "anonymous_identity" configuration field has more than one
semantic meaning. For tunneled EAP methods, this refers to the
outer EAP identity. For EAP-SIM, this refers to the pseudonym
identity. Also, interestingly, EAP-SIM can overwrite the
"anonymous_identity" field if one is provided to it by the
authenticator.
When EAP-SIM is tunneled within an outer method, it makes sense
to only use this value for the outer method, since it's unlikely
that this will also be valid as an identity for the inner EAP-SIM
method. Also, presumably since the outer method protects the
EAP-SIM transaction, there is no need for a pseudonym in this
usage.
Similarly, if EAP-SIM is being used as an inner method, it must
not push the pseudonym identity using eap_set_anon_id() since it
could overwrite the identity for the outer EAP method.

Issue:
------
The test setup has 2 peers running MACsec in PSK mode, Peer A with
MAC address higher than MAC Address of peer B. Test sequence is
1. Peer B starts with actor_priority 255
2. Peer A starts with priority 16, becomes key server.
3. Peer A stops..
4. Peer A restarts with priority 255, but because of the stale values
participant->is_key_server(=TRUE) and participant->is_elected(=TRUE)
it continues to remain as Key Server.
5. For peer B, key server election happens and since it has lower MAC
address as compared to MAC address of A, it becomes the key server.
Now we have 2 key servers in CA and is not correct.
Root-cause & fix:

This change is just making the implementation easier to understand while
not actually changing the behavior.

Unlike the EMSKname and rRK derivations, rIK derivation is actually
using the "optional data" component in the context data (see RFC 5295).
RFC 6696 defines that optional data to be the cryptosuite field for rIK.
This was missing from the previous implementation and that resulted in
incorrect rIK being derived.
In addition, the rIK Label string does not actually include the "EAP "
prefix in the way as the rRK Label in RFC 6696 does. This would also
have resulted in incorrect rIK value.
Fix rIK derivation by adding the cryptosuite value into the KDF context
data and fixing the label string. This change is not backwards
compatible and breaks all ERP use cases (including FILS shared key
authentication) with older (broken) and new (fixed)
hostapd/wpa_supplicant builds.

The new FILS-HLP-RX control interface event is now used to report
received FILS HLP responses from (Re)Association Response frame as a
response to the HLP requests configured with FILS_HLP_REQ_ADD.
