fa16028d0f Add generic infrastructure for Probe Request callbacks
Instead of calling specific Probe Request handler functions, use a
generic mechanism that allows multiple callback functions to be
registered for getting notification on receive Probe Request frames.

077a781f7a WPS: Add support for setting timeout for PIN
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.

6ce4b59342 WPS: Fix hostapd runtime WPS configuration after Enrollee run
If the AP is configured with WPS, we need to update the local WPS data
in order to provide correct credentials for Enrollees.

143a4bf632 WPS: Add a workaround for static WEP with Windows network probe
Windows XP and Vista clients can get confused about EAP-Identity/Request
when they probe the network with EAPOL-Start. In such a case, they may
assume the network is using IEEE 802.1X and prompt user for a
certificate while the correct (non-WPS) behavior would be to ask for the
static WEP key. As a workaround, use Microsoft Provisioning IE to
advertise that legacy 802.1X is not supported.

This seems to make Windows ask for a static WEP key when adding a new
network, but at least Windows XP SP3 was still marking IEEE 802.1X
enabled for the network. Anyway, this is better than just leaving the
network configured with IEEE 802.1X and automatic WEP key distribution.

e1ee6b600b WPS: Add support for NFC out-of-band mechanism
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:

Example configuration.
CONFIG_WPS=y
CONFIG_WPS_NFC=y
CONFIG_WPS_NFC_PN531=y

I used NFC device "NXP PN531". The NFC device access method is
confidential, so I used outer library. Please download below files from
https://www.saice-wpsnfc.bz/index.php

<WiFi test>
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

24466b188a WPS: Convert WEP key to hex
Use of hex is safer since the enrollee may configure AP with 5 or 13
random octets of binary data as the key.

d5e2b2d274 WPS UFD: Use pre-configured DH keys only with OOB
The old behavior of generating new DH keys can be maintained for non-OOB
cases and only OOB (in this case, with UFD) will use the pre-configured
DH keys to allow the public key hash to be checked.

7cbf51bbd8 WPS UFD: Remove oob_dev pointer from wps_context
This pointer and the especially the oob_dev->device_path does not remain
valid, so better not save it any longer than it is needed.

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.

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.

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.

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.

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.
