70e070461d WPS UFD: Use private data structure for oob_device_data
This gets rid of global variable use and may be needed to allow
concurrent access in some case if the interface is extended.

46bdb83acd WPS: Add UFD support (USBA out-of-band mechanism)
This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following UFD methods can be used:
- Enrollee PIN with UFD
- Registrar PIN with UFD
- unencrypted credential with UFD

Encrypted credentials are not supported.

Enrollee side operation:
wpa_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

wpa_cli -i ath0 wps_oob ufd /mnt/ pin-r

Registrar side operation:
./hostapd_cli -i ath0 wps_oob <device type> <mount point> <oob method>
    oob method = pin-e/pin-r/cred

hostapd_cli -i ath0 wps_oob ufd /mnt/ cred

915c1ba3c5 WPS UPnP: Added support for multiple external Registrars
Allow more than one pending PutWLANMessage data to be stored (M2/M2D
from multiple external Registrars) and drop pending M2/M2D messages when
the Enrollee replies with M3.

f620268f13 WPS: Add support for external Registrars using UPnP transport
This adds mostly feature complete external Registrar support with the
main missing part being proper support for multiple external Registrars
working at the same time and processing of concurrent registrations when
using an external Registrar.

This code is based on Sony/Saice implementation
(https://www.saice-wpsnfc.bz/) and the changes made by Ted Merrill
(Atheros) to make it more suitable for hostapd design and embedded
systems. Some of the UPnP code is based on Intel's libupnp. Copyrights
and licensing are explained in src/wps/wps_upnp.c in more detail.

3b2cf800af WPS: Lock AP Setup on multiple AP PIN validation failures
If a Registrar tries to configure the AP, but fails to validate the
device password (AP PIN), lock the AP setup after four failures. This
protects the AP PIN against brute force guessing attacks.

4c29cae932 Added ap_settings option for overriding WPS AP Settings in M7
This optional configuration parameter can be used to override AP
Settings attributes in M7 similarly to extra_cred option for Credential
attribute(s) in M8.

aabe26a136 WPS: Added option to disable AP auto-config on first registration
This operation can now be moved into an external program by configuring
hostapd with wps_cred_processing=1 and skip_cred_build=1. A new
ctrl_iface message (WPS-REG-SUCCESS <Enrollee MAC addr> <UUID-E>) will
be used to notify external programs of each successful registration and
that can be used as a tricker to move from unconfigured to configured
state.

eca6e0a9a5 WPS: Provide the unparsed Credential attribute to cred_cb()
This makes it easier to pass the credential data to external programs
(e.g., Network Manager) for processing. The actual use of this data is
not yet included in hostapd/wpa_supplicant.

41c00105f2 Removed registrar pointer from wps_config and wps_data
wps_context::registrar can be used as the only location for this
pointer.

5a8c6d3353 Removed duplicated authenticator yes/no from wps_config and wps_data
wps_context::ap is available for this purpose and there is no need to
change between AP and not AP between protocol runs.

84f5b41fc1 WPS: Cleanup UUID and MAC address configuration
No need to configure these separately for each Enrollee in wps_config
since wps_context is now used both for Registrar and Enrollee.

469fc3a41f WPS: Added callback for failure-after-M2/M2D
This callback is now used to stop wpa_supplicant from trying to continue
using parameters (most likely, device password) that do not work in a
loop. In addition, wpa_gui can now notify user of failed registration.

4b68290e77 WPS: Added event callback and M2D notification
The event callback will be used for various event messages and the M2D
notification is the first such message. It is used to notify wpa_gui
about Registrar not yet knowing the device password (PIN).

351f09a221 WPS: Added support for fragmented WPS IE in Beacon and Probe Response
Fragment WPS IE if needed to fit into the IE length limits in hostapd
and Reassemble WPS IE data from multiple IEs in wpa_supplicant.

In addition, moved WPS code from events.c into wps_supplicant.c to clean
up module interfaces.

b8a8c299c8 WPS: Moved WPS IE building for ProbeReq/AssocReq into wps.c
These functions fit in better with the category of functions included in
wps.c. wps_common.c is now used for generic helper functions (currently,
only crypto code).

c0d041d9a7 WPS: Moved ProbeReq/AssocReq WPS IE building into wps_common.c
This code and the related attributes are not specific to Enrollee
functionality, so wps_common.c is the correct location for them.

IE for Probe Request.

eb76b7e3ff WPS: Parse Request Type from WPS IE in (Re)AssocReq and derive mgmt keys
WPS IE is now passed from hostapd association processing into EAP-WSC
and WPS processing. Request Type attribute is parsed from this
information and if the request is for a WLAN Manager Registrar,
additional management keys are derived (to be used with UPnP).

bcbbc7af45 WPS: Merged two cred_cb variables into the same one
Previously, wpa_supplicant as Enrollee case was handled using a
different callback function pointer. However, now that the wps_context
structure is allocated for all cases, the same variable can be used in
all cases.

ad08c3633c Added preliminary Wi-Fi Protected Setup (WPS) implementation
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.
