Store permanent username (i.e., including prefix character) instead of
IMSI in the SQLite DB. Convert the string to a string since the EAP-AKA

Since the EAP-SIM/AKA identities are ASCII strings, there is no need to
use more complex way for storing and passing them. In addition, be more
strict about enforcing username (i.e., no realm part) to be used in the

This EAP type uses a vendor specific expanded EAP header to encapsulate

the EAP peer. In other words, this method includes only server
authentication. The peer is configured with only the ca_cert parameter

cases where the network provides free access to anyone, but use of RSN

There are separate states for these, so we can't really get into this
situation unless somebody tries to do multiple things at the same
time. p2p_connect stops find and CONNECT state is used to probe the peer
on its Listen channel with GO Negotiation Request frames. Similarly,
p2p_invite() stops find and INVITE state is used to probe the peer on
its Listen channel with Invitation Request frames. The older mechanism
of using Search state functionality to find the peer can be removed.

At least some error paths (e.g., hitting the limit on hunt-and-peck

allocations. Avoid this by setting the pointers to NULL after they have
been freed instead of trying to free the data structure in a location
where some external references cannot be cleared. [Bug 453]

os_random() may not be seeded properly, so use stronger mechanism for
generating the password id for NFC password tokens.
Signed-hostap: Jouni Malinen <j@w1.fi>
The new hostapd ctrl_iface command WPS_NFC_TOKEN can now be used to
manage AP-as-Enrollee operations with NFC password token. WPS/NDEF
parameters to this command can be used to generate a new NFC password
token. enable/disable parameters can be used to enable/disable use of
NFC password token (instead of AP PIN) for external Registrars.
A preconfigured NFS password token can be used by providing its
parameters with new hostapd.conf fields wps_nfc_dev_pw_id,
wps_nfc_dh_pubkey, wps_nfc_dh_privkey, and wps_nfc_dev_pw. This use
will also depend on WPS_NFC_TOKEN enable/disable commands, i.e., the
configured NFS password token is disabled by default.

Signed-hostap: Jouni Malinen <j@w1.fi>
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.

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.
Signed-hostap: Jouni Malinen <j@w1.fi>
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.

The OOB Device Password is passed in as a hexdump of the real Device

Previously, only the maximum length 32 octets for OOB device password
was accepted. Since the specification allows a shorter password to be

lengths 16..32.

The earlier WPS 2.0 changes did not increase the wpabuf size when

Previously, the STA entry was removed only from the driver and the STA
entry within hostapd was just marked disassociated. However, this left
the WPA authenticator state machine with an entry and the session was

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.

In the P2P specification v1.1, the P2P Client Discoverability bit is

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.

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.

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.
