a565c23bf3 WPS: Fix regression in post-WPS scan optimization
Commit 3c85f144ce fixed issues with P2P
Action frame TX after disconnection by clearing wpa_s->assoc_freq.
This resulted in a regression to the post-WPS scan optimization that
used wpa_s->assoc_freq to enable fast single-channel scan. Fix this by
copying wpa_s->assoc_freq to a local variable before calling
wpa_supplicant_deauthenticate() that ends up calling
wpa_supplicant_mark_disassoc() which will clear assoc_freq.

32cdcf15b2 WPS: Disable AP PIN after 10 consecutive failures
While the exponential increase in the lockout period provides an
efficient mitigation mechanism against brute force attacks, this
additional trigger to enter indefinite lockout period (cleared by
restarting hostapd) will limit attacks even further by giving maximum of
10 attempts (without authorized user action) even in a very long term
attack.

1e7fb4f1b7 WPS: Use single channel scan if AP channel already known
If the BSSID of the AP is specified in the WPS command, the target
AP is likely already in the BSS table and its operating channel is
known. Use this information to speed up connection by only scanning
the known channel.

d9d87c3357 Disassociate when starting WPS search
Previously, the WPS scans could have been done in associated state if we
happened to be associated when the request to use WPS was received. This
can slow down scanning and end up in unexpected state if no WPS
association is tried. Avoid these issues by disconnecting when WPS
search is started.

0b7a25c00f Use normal scan before sched_scan if that can speed up connection
When normal scan can speed up operations, use that for the first three
scan runs before starting the sched_scan to allow user space sleep more.
We do this only if the normal scan has functionality that is suitable
for this or if the sched_scan does not have better support for multiple
SSIDs.

Do not emit network objects during P2P group formation since such

Persistent group objects only represent the info needed to recreate the

This makes it easier for external programs to show WPS information
since they do not need to parse the WPS IE themselves anymore.

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.

49eba5f82f WPS: Workaround mixed-mode WPA+WPA2 auth type in credentials
An SMC router was reported to use 0x22 (WPAPSK + WPA2PSK) in the
authentication type of the provisioned credential and wpa_supplicant
rejected this as invalid. Work around this by replacing WPAPSK + WPA2PSK
with WPA2PSK.

73267b9ca4 WPS: Fix local configuration update after AP configuration
Update credential to only include a single authentication and
encryption type in case the AP configuration includes more than one
option. Without this, the credential would be rejected if the AP was
configured to allow more than one authentication type.

2d5b792d2b Add preliminary hostapd data structure initialization for AP mode
wpa_supplicant can now initialize hostapd data structures when mode=2 is
used to set up an AP. The hostapd configuration is not yet set based on
wpa_supplicant network configuration block. In addition, the glue code
for hostapd driver_ops needs number of functions that will be needed for
AP functionality.

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

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.)

through internal registrar

7cc1b6c900 WPS: Add a workaround for TKIP/CCMP mixed mode credentials
Many deployed APs do not handle negotiation of security parameters well
when both TKIP and CCMP (or both WPA and WPA2) are enabled. The most
common end result seems to be ending up with the least secure option..

As a workaround, check whether the AP advertises WPA2/CCMP in Beacon
frames and add those options for the credential if needed. This allows
the client to select the most secure configuration regardless of how
broken the AP's WPS implementation is as far as auth/encr type
negotiation is concerned.

522b5b6ed3 WPS: Fix WEP key index to use 1..4 instead of 0..3
It seems that WFA WPS spec says that default key index should be 1 (not
0). I think this meas that WEP key indexes region is not from 0 to 3,
but from 1 to 4 in WPS. At least WRT610N implemented it this way.

3b2cf800af WPS: Lock AP Setup on multiple AP PIN validation failures
If a Registrar tries to configure the AP, but fails to validate the

a609915233 Allow WPS APs for PIN enrollment even without Selected Registrar
Some WPS APs do not set Selected Registrar attribute to 1 properly when
using an external Registrar. Allow such an AP to be selected for PIN
registration after couple of scan runs that do not find APs marked with
Selected Registrar = 1. This allows wpa_supplicant to iterate through
all APs that advertise WPS support without delaying connection with
implementations that set Selected Registrar = 1 properly.

7aab82b3fe Fixed WPS credential conversion to wpa_supplicant configuration
Must not set pairwise_cipher/group_cipher for non-WPA/WPA2 networks
since the configuration parser is going to reject such values. In
addition, should not limit group_cipher to just TKIP or TKIP|CCMP just
in case the AP is using WEP as the group cipher. Default group_cipher
value can be used for all cases.

f0477201bd WPS: Fixed deinit code for freeing config and registrar data
We need to be a bit more careful when removing the WPS configuration
block since wpa_s->current_ssid may still be pointing at it. In
addition, registrar pointer in wps_context will need to be cleared
since the context data is now maintained over multiple EAP-WSC runs.
Without this, certain WPS operations could have used freed memory.
