82fb18472e WPS: Fix strict validation of (Re)Association Response
This frame is supposed to include Response Type, not Request Type
attribute.

0e2e565a44 WPS 2.0: Provide (Re)Association Response WPS IE to driver
WPS 2.0 mandates the AP to include WPS IE in (Re)Association Response
if the matching (Re)Association Request included WPS IE. Provide the
needed WPS IE information to the driver_ops API for drivers that
process association frames internally.

Note: This modifies the driver_ops API by adding a new argument to
set_ap_wps_ie().

b4e34f2fdf WPS: Make testing operations configurable at runtime
Instead of build time options (CONFIG_WPS_TESTING_EXTRA_CRED and
CONFIG_WPS_EXTENSIBILITY_TESTING), use a single build option
(CONFIG_WPS_TESTING) and runtime configuration of which testing
operations are enabled. This allows a single binary to be used
for various tests.

The runtime configuration can be done through control interface
with wpa_cli/hostapd_cli commands:
Enable extensibility tests:
set wps_version_number 0x57
Disable extensibility tests (WPS2 build):
set wps_version_number 0x20
Enable extra credential tests:
set wps_testing_dummy_cred 1
Disable extra credential tests:
set wps_testing_dummy_cred 0

ab98525399 WPS 2.0: Fix AuthorizedMACs check to accept wildcard address
We need to accept both our own address and the ff:ff:ff:ff:ff:ff
as an indication of the AP having authorized us.

252d7db297 P2P: Fill in default Config Methods in Invitation Request
If the peer is not authorized for GO Negotiation, wps_method is not
actually set. In that case, it is better to fill in our default
config methods rather than end up leaving the field to be zero.

3379a3a795 WPS: Fix Beacon WPS IE on concurrent dualband AP in PBC mode
The Beacon frame must include UUID-E and RF Bands attributes when
in active PBC mode to allow stations to figure out that two BSSes in
PBC mode is not a PBC session overlap.

e0369e3664 WPS: Use same UUID in multi-interface case
When generating the UUID based on MAC address, share the same UUID
with all interfaces. This fixes a potential issue with concurrent
dualband APs where the UUID needs to be same for PBC to work properly.

7736f18bef WPS: Cancel WPS operation on PBC session overlap detection
Previously, wpa_supplicant remaining in scanning state without
trying to connect, but there is no particular need to do that.
Instead, cancel WPS operation completely whenever PBC session
overlap is detected.

ea184114ca Allow auto-connect to request scan in associating state
Disconnection event may be received while in associating state.
Previously, wpa_supplicant could get stuck not trying to reconnect
in that case at least with nl80211. Allow scan request in this
state to avoid the issue. This helps especially with APs that do
load balancing by sending Deauthentication frame as a response to
Reassociation Request frame after successful Authentication frame
exchange.

0d0a8ca1cc Add option for disabling automatic reconnection on disconnection
ctrl_interface STA_AUTOCONNECT command can now be used to disable
automatic reconnection on receiving disconnection event. The default
behavior is for wpa_supplicant to try to reconnect automatically, i.e.,
to maintain previous behavior.

e2197af1b2 P2P: Make sure parsed Device Name gets null terminated
If the msg->device_name buffer is filled from two different sources,
the copy from the P2P Device Info attribute needs to make sure that
the values gets null terminated to match the length of the correct
string should the other place use another string (which is not really
allowed by the spec, but could happen).

b73bf0a74b P2P: Stop connection attempt on PBC session overlap
The overlap condition cannot disappear before group formation timeout
hits, so there is no point in continuing in this case and failure can
be indicated immediately.

3094d4837a P2P: Use group formation timeout (but longer one) with join-a-group
This allows the pending group interface to be removed if we fail
to join a running group. A longer than 15 second timeout is needed
here since the GO may not have authorized our connection yet.

2f9929ffcc WPS: Allow pending WPS operation to be cancelled
A new ctrl_interface command, WPS_CANCEL, can now be used to cancel
a pending or ongoing WPS operation. For now, this is only available
with wpa_supplicant (either in station or AP mode). Similar
functionality should be added for hostapd, too.

fbe7027239 P2P: Provide local event on GO Neg Req rejection
If an authorized (p2p_connect used locally) GO Negotiation is
rejected when receiving GO Negotiation Request from the peer,
indicate the failure with a ctrl_interface P2P-GO-NEG-FAILURE
event. Previously, this event was only shown on the peer (i.e.,
the device receiving the GO Negotiation Response with non-zero
Status code).

f8d0131a11 P2P: Use operating frequency from peer table as backup for join
The scan operation before Provision Discovery Request may not include
the GO. However, we are likely to have the GO in our P2P peer table,
so use that information to figure out the operating channel if BSS
table entry is not available.

operation to be started if this state is detected.

This can happen, e.g., when a P2P client connects to a P2P group
using the infrastructure WLAN interface instead of P2P group
interface. In that case, the P2P client may behave as if the GO
would be a P2P Manager WLAN AP.
