Control interface command "NFC_GET_HANDOVER_SEL NDEF WPS-CR" can now be
used to fetch WPS carrier record from hostapd.

Add some more functionality for BSS Transition Management:
- advertise support for BSS Transition Management in extended
capabilities element
- add hostapd.conf parameter bss_transition=1 for enabling support
for BSS Transition Management
- add "hostapd_cli disassoc_imminent <STA> <num TBTTs>" for sending
disassociation imminent notifications for testing purposes
- wpa_supplicant: trigger a new scan to find another BSS if the
current AP indicates disassociation imminent (TODO: the old AP needs
to be marked to use lower priority to avoid re-selecting it)

The UFD (USB flash drive) configuration method was deprecated in WSC
2.0. Since this is not known to be used, remove the UFD implementation
from hostapd and wpa_supplicant to allow the WPS implementation to be
cleaned up. This removes the now unused OOB operations and ctrl_iface
commands that had already been deprecated by the new NFC operations.

The old WPS interface for using NFC has no known deployments and even
the binary libraries referenced here are not easily available anymore.
Since the new interface for using NFC with WPS covers the same
functionality, remove the old implementation to clean up WPS
implementation.

Commit 4c374cde2f added a new wps_cancel
command, but didn't add it to the usage text in hostapd_cli. Add an
entry for this command.

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 new hostapd ctrl_iface command WPS_NFC_CONFIG_TOKEN can now be used
to fetch payload for an NFC configuration token so that an external
program can be used to write this on an NFC tag.

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.

Implement wps_cancel for hostapd similarly to how it was already
supported in wpa_supplicant AP mode.

Simplify licensing terms for hostap.git by selecting the BSD license
alternative for any future distribution. This drops the GPL v2
alternative from distribution terms and from contribution requirements.
The BSD license alternative that has been used in hostap.git (the one
with advertisement clause removed) is compatible with GPL and as such
the software in hostap.git can still be used with GPL projects. In
addition, any new contribution to hostap.git is expected to be licensed
under the BSD terms that allow the changes to be merged into older
hostap repositories that still include the GPL v2 alternative.

"hostapd_cli ess_disassoc (STA addr) (URL)" can now be used to send
an ESS Dissassociation Imminent notification to the STA. This event
is shown in wpa_supplicant ctrl_iface monitors (e.g., wpa_cli):
"WNM: ESS Disassociation Imminent - session_info_url=http://example.com/session/"
Instead of build time options (CONFIG_WPS_TESTING_EXTRA_CRED and
CONFIG_WPS_EXTENSIBILITY_TESTING), use a single build option
(CONFIG_WPS_TESTING) and runtime configuration of which testing
operations are enabled. This allows a single binary to be used
for various tests.
The runtime configuration can be done through control interface
with wpa_cli/hostapd_cli commands:
Enable extensibility tests:
set wps_version_number 0x57
Disable extensibility tests (WPS2 build):
set wps_version_number 0x20
Enable extra credential tests:
set wps_testing_dummy_cred 1
Disable extra credential tests:
set wps_testing_dummy_cred 0
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.
A new hostapd_cli command, wps_ap_pin, can now be used to manage
AP PIN at runtime. This can be used to generate a random AP PIN and
to only enable the AP PIN for short period (e.g., based on user
action on the AP device). Use of random AP PIN that is only enabled
for short duration is highly recommended to avoid security issues
with a static AP PIN.
This can be used to test 802.11w by sending a protected or unprotected
deauth/disassoc frame.
hostapd_cli deauth <dst addr> test=<0/1>
hostapd_cli disassoc <dst addr> test=<0/1>
test=0: unprotected
test=1: protected
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.
In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.
hostapd_cli wps_pin command can now have an optional timeout
parameter that sets the PIN lifetime in seconds. This can be used
to reduce the likelihood of someone else using the PIN should an
active PIN be left in the Registrar.
The new file wps_nfc.c and ndef.c implements NFC device independent
operation, wps_nfc_pn531.c implements NFC device dependent operation.
This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar
Following NFC methods can be used:
- Enrollee PIN with NFC
- Registrar PIN with NFC
- unencrypted credential with NFC
Encrypted credentials are not supported.
Enrollee side operation:
Registrar side operation:

The hostapd/wpa_supplicant with this patch passed below tests on
"Wi-Fi WPS Test Plan Version 1.6".
4.2.5 Add device using NFC Method with password token
(I used SONY STA instead of NXP STA.)
4.2.6 Add device using NFC Method with configuration token
5.1.9 Add to AP using NFC Method with password token
through internal registrar
(I used SONY AP instead of NXP AP.)
5.1.10 Add to AP using NFC Method with configuration token
through internal registrar
The default interval is now 5 seconds (used to be 1 second for
interactive mode and 2 seconds for wpa_cli -a). The interval can be
changed with -G<seconds> command line option.
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.
Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.
