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
keys do not match and no STA can forge group-addressed frames.
An additional mechanism in the AP needs to be provided to handle some
group-addressed frames, e.g., by converting DHCP packets to unicast
IEEE 802.11 frames regardless of their destination IP address and by
providing Proxy ARP functionality.

Commit 6b56cc2d97 added retries of
provision discovery request frames in IDLE state. However, it did not
make the p2p_find case behave consistently with the new limitied retry
behavior. This can result in way too many and frequent PD retries. Fix
this by extending the previous commit to address PD retries and maximum
retry limit consistently regardless of whether p2p_find is running.

Commit 1b487b8b1e added CH_SWITCH
event for nl80211, but ended up using hostapd_hw_get_channel()
regardless of build configuration for driver interfaces. This
function is not always available, so make its use conditional
on NEED_AP_MLME.

Commit d9cc4646eb added
crypto_hash_{init,update,finish}() wrappers for OpenSSL, but it

to return error codes from the functions while older versions used
void functions. Add support for the older versions, too.

This functionality could be shared for other commands, too, so move
it to a common function. In addition, implement the validation in a

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
iterations) could have resulted in double-freeing of some memory
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]

The previously used limit (10) is too small for practical purposes since
it can result in about 1 out of 1000 authentication attempts failing.
Increase the limit to 30 to avoid such issues. [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.

The AP PIN on wps_reg command can now be replaced with special value

The new hostapd ctrl_iface command WPS_NFC_CONFIG_TOKEN can now be used

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
Password (16..32 octets of arbitrary binary data). The hexdump needs to
be converted to binary form before passing it for WPS processing.
Signed-hostap: Jouni Malinen <j@w1.fi>
Previously, only the maximum length 32 octets for OOB device password
was accepted. Since the specification allows a shorter password to be
used with limited OOB mechanism (e.g., small NFC tag), we should accept
lengths 16..32.

The earlier WPS 2.0 changes did not increase the wpabuf size when
adding a new attribute to the NFC password token. This could result
in aborting the application on wpabuf overflow if NFC out-of-band
mechanism is used with WPS 2.0 enabled.

Some drivers may independently decide to switch channels. Handle this by

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
not terminated properly. In addition, the STA entry could have remaining
indefinitely if the STA did not reconnect after TKIP countermeasures.
Fix this by removing the STA entry from hostapd instead of just leaving
it disassociated.
