AES uses the same 128-bit block size with 128, 192, 256 bit keys, so use
the fixed block size definition instead of trying to dynamically set the

The group matching should be done by comparing the P2P Interface Address
(which the group_bssid here is) to the group's BSSID and not the group
ID (which uses P2P Device Address and would have also needed the SSID).
Though, it should be noted that this case cannot really happen since a
GO in an active group would never be invited to join another group in
its GO role (i.e., if it receives an Invitation Request, it will reply
in P2P Device role). As such, this fix does not really change any
observable behavior, but anyway, it is good to keep the implementation
here consistent with the Invitation Request case.

This bit is set in the code path that handles keys and certs from places
other than OpenSSL authentication engines. Setting this bit causes
authentication to fail when the server provides certificates that don't
match the client certificate authority.
Commit 05ab9712b9 added support for
fetching WPA PSK from an external RADIUS server and changed
hostapd_wpa_auth_get_psk() to always return the RADIUS supplied PSK (if
set) and ignore the prev_psk parameter for iteration. Fix this by
appending the RADIUS supplied PSK to the list iterated by
hostapd_get_psk and thus returning NULL when prev_psk == sta->psk
(RADIUS).

This new mechanism can be used to make wpa_supplicant using external
storage (e.g., key store in the operating system) for passwords,
passphrases, and PSKs. This commit is only adding the framework part
needed to support this, i.e., no actual configuration parameter can
yet use this new mechanism. In addition, only a simple test backend
is added to allow developer testing of the functionality.

disable_dgaf=1 in hostapd.conf can now be used to disable downstream
group-addressed forwarding (DGAF). In this configuration, a unique
GTK (and IGTK) is provided to each STA in the BSS to make sure the

An additional mechanism in the AP needs to be provided to handle some

IEEE 802.11 frames regardless of their destination IP address and by
providing Proxy ARP functionality.

Commit 6b56cc2d97 added retries of

this by extending the previous commit to address PD retries and maximum

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

os_random() may not be seeded properly, so use stronger mechanism for

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.

This adds a cleaner mechanism for handling NFC Password Tokens in the

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

has an NFC device that is used to read an NFC tag from the station
Enrollee.

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 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
