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.

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).

52eb293dd2 WPS: Add support for AP reconfiguration with wps_reg
wpa_supplicant can now reconfigure the AP by acting as an External
Registrar with the wps_reg command. Previously, this was only used
to fetch the current AP settings, but now the wps_reg command has
optional arguments which can be used to provide the new AP
configuration. When the new parameters are set, the WPS protocol run
is allowed to continue through M8 to reconfigure the AP instead of
stopping at M7.

4625a47f4b WPS: Change wpa_supplicant wps_reg to not send out M8
Since we do not currently support changing the AP settings received
from M7, there is no point in actually sending out the M8 that would
likely trigger the AP to reconfigure itself and potentially reboot.
For now, we just receive the AP settings in M7 and add a local network
configuration block based on those, but NACK the message. This makes
wps_reg work like wps_pin, but by using the AP PIN instead of a client
PIN.

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.

b3ddab2122 WPS: Pad DH Public Key and Shared Key to 192 octets
WPS spec is not very specific on the presentation used for the DH
values. The Public Key attribute is described to be 192 octets long, so
that could be interpreted to imply that other places use fixed length
presentation for the DH keys. Change the DH derivation to use fixed
length bufferd by zero padding them from beginning if needed. This can
resolve infrequent (about 1/256 chance for both Public Key and Shared
Key being shorter) interop issues.

e29bcf9eab WPS: Check Device Password ID attribute only if present in AP search
I can't pass the "Wi-Fi WPS Test Plan Version 1.0 [5.1.4. Add to AP
using PIN Config method and PASS PHRASE through wired external
registrar]". The wpa_supplicant-0.6.7 can't recoginize the testbed
AP(BCM94704AGRRev-E.2.4) as WPS PIN AP. Because after PIN entered, the
AP sends Selected Registrar attribute=0 and not send Device Password ID
attribute.

The proposed change as-is removed validation of Selected Registrar
attribute completely. However, that part is not included in this commit
since it can cause problems for environments with multiple WPS-enabled
APs. Another workaround for this will be considered in wpa_supplicant
scanning process (e.g., start trying to use WPS with APs that do not set
Selected Registrar to TRUE after couple of scan runs that do not find
any APs with Selected Registrar TRUE).

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).

7d7b8e960a WPS: Split wps_common.c into parts
To make it easier to find various functions, attribute functions were
split into wps_attr_{build,parse,process}.c.

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.

Use configured device data instead of hardcoded values to generate WPS
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.

ff434cbdda WPS: Moved device attributes into wps_context::dev for Enrollee case
Previously, hardcoded values were used in wps_enrollee.c. These are now
moved into shared data in struct wps_context. In case of
AP/Authenticator, these are initialized in wps_hostapd.c. In case of
client/supplicant, these are now initialized in EAP-WSC peer method,
but will probably end up being moved into higher layer for better
configuration.

9d695f3dd0 WPS: Update supplicant configuration when acting as an external Registrar
This allows the network to be used after the Registrar configuration
step. The local WPS network is replaced with a new network block
similarly to the case of acting as an Enrollee.

3f42d42c07 WPS: Moved Credential building to use struct wps_credential
This makes it easier to store old AP settings into wps->cred (and allow
them to modified and taken into use in the future). Separation between
Credential and AP Settings building is also cleaner in this design.

96a2ed9f50 WPS: Process old AP Settings in M7 when registering as external Registrar
The old (i.e., currently used) AP Settings are processed. For now, they
are copied as-is into M8 as new AP Settings to avoid changing
configuration. This should be changed to allow external programs (e.g.,
GUI) to fetch the old AP settings over ctrl_iface and then allow
settings to be changed before sending M8 with the new settings.

fced73755f WPS: Moved Credential and AP Settings processing in common code
The core processing of attributes into struct wps_credential is now in
wps_common.c (was in wps_enrollee.c), so that the same code can be
shared with Registrar.

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.
