e47588279a WPS: Report NFC connection handover completion differently
Instead of reporting only one connection handover message, report
completion of NFC connection handover with carrier record from both the
request and select messages.

bbaaaee171 WPS: Fetch only the carrier record from wpa_supplicant for NFC
Since there could be multiple carrier records, it is cleaner to build
only the WPS carrier record instead of full NFC connection handover
request within wpa_supplicant.

318e772ad1 WPS: Update configuration file after re-enabling networks
Network blocks are disabled during a WPS provisioning step and 10
seconds after this to allow the newly provisioned network to be
selected. The disabled=1 flag gets written to the configuration file
when the credential is added since it happens during this process.
Update the file again after the networks have been re-enabled to avoid
leaving the configuration file into state that is not consistent with
the running configuration.

6fbcbc07e4 WPS: Optimize post-WPS scan even if EAP-Failure is not received
Commit 17a4734dc4 shall optimize the
post-WPS scan based on the channel used during the provisioning only
when the EAP-Failure frame is received. In cases where the EAP-Failure
frame is missed, this optimization shall not happen resulting in the
scan in all the channels thus consuming more time for the connection.
This commit enhances this by storing the requisite information after
the M8 frame is received.

207fb86411 WPS: Remove deprecated UFD config method and OOB ctrl_iface
The UFD (USB flash drive) configuration method was deprecated in WSC
2.0. Since this is not known to be used, remove the UFD implementation
from hostapd and wpa_supplicant to allow the WPS implementation to be
cleaned up. This removes the now unused OOB operations and ctrl_iface
commands that had already been deprecated by the new NFC operations.

b363121a20 WPS: Reject invalid credential more cleanly
If WPS Registrar tries to provision a WPA/WPA2-Personal network without
including a valid Network Key, the network block cannot be used to
connect to the network. Reject such credential without adding the
network block. This makes wpa_supplicant send WSC_NACK as a response to
the invalid Credential and stop the provisioning process immediately
rather than only after trying unsuccessfully to connect to the network.

2c1e557507 WPS: Fix BSSID filter handling
If WPS commands are used with a specific BSSID instead of wildcard,
the BSSID that was supposed to be used only for the provisioning step
may end up getting copied to the network block that gets provisioned
based on the WPS credentials. Fix this by clearing ssid->bssid_set
when creating the network block by replacing the block used for WPS
provisioning.

This issue could show up with the provisioned network not getting
selected properly with APs that have multiple radios. Depending on
the driver, this could result in only a single one of the available
BSSes being available or the connection failing completely.

ef10f4733f WPS ER: Add wps_er_set_config to use local configuration
This command can be used to enroll a network based on a local
network configuration block instead of having to (re-)learn the
current AP settings with wps_er_learn.

092acb5441 WPS: Add virtual flags in Config Methods for WPS 2.0 if needed
This is a workaround for incorrect configuration (missing
virtual/physical identifier for config methods) for WPS 2.0 to
allow unmodified configuration from WPS 1.0 to be used while
enforcing compliant WPS 2.0 values.

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.

31fcea931d WPS 2.0: Add support for AuthorizedMACs attribute
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.

41e650ae5c WPS: Use different scan result sorting rules when doing WPS provisioning
The AP configuration may change after provisioning, so it is better
not to use the current security policy to prioritize results. Instead,
use WPS Selected Registrar attribute as the main sorting key and use
signal strength next without considering security policy or rate sets.
The non-WPS provisioning case remains as-is, i.e., this change applies
only when trying to find an AP for WPS provisioning.

0848668513 WPS ER: Allow AP filtering based on IP address

to configure a filter to only allow UPnP SSDP messages from the

to a single AP and filters out all other devices in the network.

17a4734dc4 Optimize post-WPS scan based on channel used during provisioning
Scan only the frequency that was used during provisioning during the
first five scans for the connection. This speeds up connection in the
most likely case where the AP remains on the same channel. If the AP is
not found after these initial scans, all channels will be scanned.
