d0184cb25c UPnP: Renamed PutWLANResponse callback function to match action
No point in adding extra "event_" to the name.

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.

e1bad1cd7d UPnP: Workaround bogus NewWLANEventMAC in PutWLANResponse
It looks like Intel wsccmd may send a bogus NewWLANEventMAC
(11:22:33:44:55:66) when acting as an wired external Registrar. Work
around this by going through all STAs if the address does not match and
pick the STA that is in an ongoing WPS registration.

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.

401e039633 Allow WPS device strings to be unconfigured
Previous version was causing a NULL pointer dereference if a required
string was not set in configuration. It is better to make these
optional.

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.

d745c7cc1a Added wps_cred_processing configuration option for hostapd
This behaves like the one in wpa_supplicant, i.e., hostapd can be
configured not to process new credentials (AP settings) internally and
instead pass the WPS attributes for an external program to process over
ctrl_iface.

42d16805c9 Enable wpa_msg() for hostapd
Use wpa_msg() like wpa_supplicant in order to avoid having to use direct
hostapd_ctrl_iface_send() calls.

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.

bfddd95c9e Split hostapd/driver.h into two files
driver.h contains the definitions needed in driver wrapper
implementations (driver_*.c) and driver_i.h contains the definitions
that are used in core hostapd code to interact with the driver wrappers.

79da74a20c WPS: Generate UUID based on MAC address, if not set
Generate a SHA1 hash -based UUID from the local MAC address if the UUID
was not configured. This makes it easier to prepare for WPS since there
is no need to generate an UUID.

08bec36178 WPS: Added support for wildcard PINs that work with any UUID-E
Since the Registrar may not yet know the UUID-E when a new PIN is
entered, use of a wildcard PIN that works with any UUID-E can be useful.
Such a PIN will be bound to the first Enrollee trying to use it and it
will be invalidated after the first use.

43fb17940f WPS: Fixed hostapd to use allocated buffers for device attributes
Previous version did not handle re-configuration correctly since WPS
context data was pointing to old (now freed) strings.

120bd30c34 WPS: Moved RF Bands processing into wps_dev_attr.c
This allows the RF Bands attribute to be configured and stored.

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.
