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.
This avoids issues to start the GO in cases where the preferred
frequency list from the driver may include channels that are not
currently enabled for P2P GO use (e.g., 5 GHz band in world roaming
configuration).

This adds the same changes to EAP-AKA that were previous done for

Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
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:
-----------------

otx, etc. need to be cleared. In MACsec PSK mode, these stale values

The hostapd processing of the AES-SIV AAD was incorrect. The design for
the AAD changed between P802.11ai/D7.0 and D8.0 from a single vector
with concatenated data to separate vectors. The change in the
implementation had missed the change in the aes_siv_decrypt() call for

Fix this by using the correct numbers of vectors in the SIV AAD so that
all the vectors get checked. The last vector was also 14 octets too long
due to incorrect starting pointer, so fix that as well. The changes here

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 "

have resulted in incorrect rIK value.
Fix rIK derivation by adding the cryptosuite value into the KDF context

The previous implementation worked for Association Request frames by

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

ap_sta_disassociate/ap_sta_deauthenticate/ap_sta_disconnect all use
disassociation instead of deauthentication. In driver_nl80211,
i802_sta_deauth() is routed to i802_sta_disassoc().

Supported Rates element is not present in DMG/IEEE 802.11ad frames. Make
copy_supp_rates() immediately return with success if hardware mode is
IEEE 802.11ad.

It was possible that nl80211_get_hw_feature_data() function would return
NULL when num_modes is not set to zero. This might result in a later crash
when accessing hw.modes. This may be reproduced with hwsim oom tests, for
example, dbus_connect_oom.
Fix that by zeroing num_modes if NULL is returned.

The new BEACON-REQ-TX-STATUS control interface event is now used to
report whether a beacon request (from REQ_BEACON command) was delivered
successfully. This event has the following parameters: <STA address>
<dialog token> <ack=0/1>.

The new control interface command "REQ_BEACON <STA addr>
[req_mode=<mode>] <beacon request>" can now be used to request hostapd
to transmit a measurement request to request a beacon report from an
associated STA. This command returns the assigned dialog token (1-255)
or FAIL on failure.

The loop to add hash values was supposed to be limited to at most 10000
values, but the count variable was not being decremented in the loop.
Fix this by decrementing counting for each iteration. This fixes
ANQP-element format in the unlikely case of there being more than 10000
configuration realms.
