0848668513 WPS ER: Allow AP filtering based on IP address
wps_er_start command now takes an optional parameter that can be used
to configure a filter to only allow UPnP SSDP messages from the
specified IP address. In practice, this limits the WPS ER operations
to a single AP and filters out all other devices in the network.

2c59362905 WPS: Add a workaround for incorrect NewWLANEventMAC format
Some ER implementation (e.g., some versions of Intel PROSet) seem to
use incorrect format for WLANEventMAC variable in PutWLANResponse.
Work around this by allowing various MAC address formats to be used
in this variable (debug message will be shown if the colon-deliminated
format specified in WFA WLANConfig 1.0 is not used).

b64576fcf5 WPS: Prefer PSK format if Enrollee does not advertise Display
Since an Enrollee that does not advertise display as one of the
Config Methods is unlikely to be able to show the ASCII passphrase
to the user, prefer PSK format with such an Enrollee to reduce key
derivation time. This can help with some low-powered devices that
would take long time to derive the PSK from the passphrase.

either based on external (to WPS) configuration or automatically set
based on some WPS attribute values from the Enrollee.

7e683ceeb4 WPS: Handle Selected Registrar as a union of info from all Registrars
Instead of using the latest selected registrar change, collect selected
registrar information separately from all registrars and use the union
of this information when building the WPS IE for Beacon and Probe
Response frames.

Note: SetSelectedRegistrar UPnP action does not include a unique
identifier, so the ER matching routine is based only on the IP address
of the ER. In theory, there could be multiple ERs using the same IP
address (but different port or URL), so there may be some corner cases
that would not always match the correct ER entry at the AP. Anyway, this
is not really expected to occur in normal use cases and even if it did
happen, the selected registrar information is not any worse than it was
before when only the last change from any registrar for being
advertized.

4bdd556886 WPS: Fix MAC Address inside Credential be that of Enrollee's
The WPS 1.0h specification is quite unclear on what exactly should be
used as the MAC Address value in the Credential and AP Settings. It
looks like this should after all be the MAC Address of the Enrollee,
so change Registrar implementation to use that address instead of the
AP BSSID.

In addition, add validation code to the Enrollee implementation to
check the MAC Address value inside Credential (and also inside AP Settings)
to make sure it matches with the Enrollee's own address. However, since
there are deployed implementations that do not follow this interpretation
of the spec, only show the mismatch in debug information to avoid breaking
interoperability with existing devices.

wps_upnp_event.c, use a generic HTTP client module to do this. The HTTP
client code can now be shared more easily for other purposes, too.

e9bcfebfce WPS: Add initial part of External Registrar functionality
This is the first step in adding support for using wpa_supplicant as a
WPS External Registrar to manage APs over UPnP. Only the device
discovery part is implemented in this commit.

0ae7b08691 Work around some gcc 4.4 strict-aliasing warnings
gcc 4.4 ends up generating strict-aliasing warnings about some very common
networking socket uses that do not really result in a real problem and
cannot be easily avoided with union-based type-punning due to struct
definitions including another struct in system header files. To avoid having
to fully disable strict-aliasing warnings, provide a mechanism to hide the
typecast from aliasing for now. A cleaner solution will hopefully be found
in the future to handle these cases.

72ffc08242 WPS: SelectedRegistrar expiration for internal PIN registrar
Though we have such a timeout when handling SetSelectedRegistrar UPnP
message from an external registrar, it looks like we don't have one when
the internal registrar is activated for PIN connection. Thus we set the
SelectedRegistrar flag when AP is activated for PIN connection but we
never reset it - not by some timeout, nor when registration succeeds.
This lead to situations where AP everlastingly declare that it is
activated for WPS PIN connection when in reality it is not.

Use the same timeout (and also success with PIN) to clear the selected
registrar flag when using internal registrar, too.

2e71444516 WPS: Abort ongoing PBC protocol run if session overlap is detected
If PBC session overlap is detected during an ongoing PBC protocol run,
reject the run (if M8, i.e., credentials, have not yet been sent). This
provides a bit longer monitoring time at the Registrar for PBC mode to
catch some cases where two Enrollees in PBC mode try to enroll
credentials at about the same time.

63330c6832 WPS: Add PBC overlap and timeout events from WPS module
This provides information about PBC mode result from the WPS Registrar
module. This could be used, e.g., to provide a user notification on the
AP UI on PBC failures.

7e3a67514f WPS: Use Config Error 12 to indicate PBC overlap in M2D
If PBC session overlap is detected between button press on the registrar
and M1 is reception, report session overlap with the Config Error
attribute in M2D to the Enrollee.

f042122a57 Allow the internal DH implementation to be overridden
Crypto library wrappers can now override the internal DH (group 5)
implementation. As a starting point, this is done with OpenSSL. The
new mechanism is currently available only for WPS (i.e., IKEv2 still
depends on the internal DH implementation).
