d7645d239d WPS: Add support for NFC configuration token from external program
The new wpa_supplicant ctrl_iface command WPS_NFC_TAG_READ can now be
used to process NFC tags read by external programs to initiate
wpa_supplicant to use NFC Configuration Token to create a new network.

0e3c16546b WPS: Use separate list of NFC Password Tokens in the Registrar
This adds a cleaner mechanism for handling NFC Password Tokens in the
WPS Registrar. There could be more than one active NFC Password Token in
use and as such, a list of tokens needs to be maintained. The old
WPS_OOB interface is still using the old mechanism that supports only a
single active NFC Password Token.

bb45b6d79a WPS: Add new mechanism for communicating NFC tag read events
hostapd ctrl_iface can now be used to deliver payload from read
operation of an NFC tag. This allows operations without having to have
low-level NFC code within hostapd. For now, the new wps_nfc_tag_read
command can be used with NFC password tokens for the case where the AP
has an NFC device that is used to read an NFC tag from the station
Enrollee.

3f2c8ba6d3 WPS: Add new mechanism for NFC config method using password token
Instead of requiring low-level access to an NFC device and synchronous
operations, the new WPS_NFC_TOKEN and WPS_NFC ctrl_iface commands can be
used to build a NFC password token and initiate WPS protocol run using
that token (or pre-configured values) as separate commands. The
WPS_NFC_TOKEN output can be written to a NFC tag using an external
program, i.e., wpa_supplicant does not need to have low-level code for
NFC operations for this.

296a34f0c1 Remove STA entry from AP when starting TKIP countermeasures

entry within hostapd was just marked disassociated. However, this left

f33bc03582 P2P: Fix P2P Client Discoverability bit updates
The P2P Client Discoverability bit is reserved in most frames and its
value in the local P2P peer table should only be updated based on P2P
Group Info attribute from a GO. Fix this by avoiding changes to this
dev_capab bit based on other P2P frames. It would be more correct to
track this separately for each group in which the peer is a member, but
since we do not do that for the other group specific information either,
this can do for now.

It should be noted that prior to commit
18485b5469 wpa_supplicant set this bit in
all P2P frames. However, that commit changed this to match the
specification, i.e., the bit is not set in frames which are received
from P2P Device role. As such, this fix is needed to be able to figure
out that a peer supports client discoverability capability after that
commit.

P2P Device supports P2P Client Discoverability, and is set to 0
otherwise. This field shall be reserved and set to 0 in all other frames
or uses.". To match with this, filter out P2P Client Discoverability bit
from frames where its use is reserved.

198f82a1e3 P2P: Ignore unexpected GO Neg Resp is we have sent Resp
There is a race condition in GO Negotiation Request frame sending and
processing that may end up with both devices sending GO Negotiation
Response. This response frame was previously accepted even if a response
had already been sent. This could result in two GO Negotiation Confirm
frames being exchanged and consequently, with two separate GO
Negotiations completing concurrently. These negotiations could result in
getting mismatching parameters (e.g., both device could believe it was
the GO).

Fix this by ignoring GO Negotiation Response from the peer if twe have
already sent a GO Negotiation Response frame and we have the higher P2P
Device Address. This is similar to the rule used to determine whether to
reply to GO Negotiation Request frame when Request was already sent,
i.e., the same direction of GO Negotiation is maintained here to enforce
that only the negotiation initiated by the device with smaller P2P
Device Address is completed.

a1d2ab329e P2P: Address race condition with GO Negotiation Request TX status
If both peers initiate GO Negotiation at about the same time, it is
possible for the GO Negotiation Request frame from the peer to be
received between the local attempt to send the GO Negotiation Request
and TX status event for that. This could result in both devices sending
GO Negotiation Response frames even though one of them should have
skipped this based which device uses a higher MAC address.

Resolve this race by incrementing go_neg_req_sent when p2p_send_action()
returns success instead of doing this from the TX status callback. If
the frame is not acknowledged, go_neg_req_sent is cleared in TX status
handler.
