This uses the new nl80211 attributes to allow the connect command to
provide bssid and freq hints to the driver without limiting roaming to
the specific BSS/frequency. This can be used by drivers that perform
internal BSS selection (WPA_DRIVER_FLAGS_BSS_SELECTION) as a candidate
for initial association.

With the license terms having been cleaned up in the hostap.git files,
there is no continued need for the additional (e) item to explicitly
acknowledge BSD license option for contributions. Since DCO v1.1 is now
available from http://developercertificate.org/ it looks reasonable to
move to the unmodified version of DCO and to the commonly used

Confirm-before-commit validation step allowed execution to continue on
error case. This could result in segfault in sae_check_confirm() if the
temporary SAE data was not available (as it would not be, e.g., in case
of an extra SAE confirm message being received after successful
exchange). Fix this by stopping SAE processing immediately after
detecting unexpected state for confirm message. In addition, make the
public sae.c functions verify sae->tmp before dereferencing it to make
this type of bugs less likely to result in critical issues.

p2p-nfc.py allowed an NFC Tag to be read and reported to wpa_supplicant
even in cases where it was explicitly asked to initiate negotiated
connection handover and return after completing this operation. The new
command line argument can be used to disable NFC Tag read operations
when a negotiated connection handover is expected.

It was possible to FAIL return for a P2P_FIND command that was issued
while an already started P2P_FIND operation was in the scan phase. This
can be confusing for upper layer software, so hide the failure report
from the ctrl_iface response. The previously started scan will continue

Previously, unconfigured state was forcing the best supported
authentication and encryption state to be shown in WPS messages,
including AP Settings in M7 in case the AP acts as an Enrollee. This is
not really correct for the AP Settings case, so change that one to
indicate the currently configured state.

The mechanism of using Status attribute in GO Negotiation Request was
used in some early specification drafts, but it is not compliant with
the current P2P specification where GO Negotiation Request is used only
for the purpose of initiating a new GO Negotiation. However, some
deployed devices use it to indicate rejection of GO Negotiation in a
case where they have sent out GO Negotiation Response with status 1. The
P2P specification explicitly disallows this.
To avoid unnecessary interoperability issues and extra frames, mark the
pending negotiation as failed and do not reply to this GO Negotiation
Request frame. Previously, GO Negotiation Response frame with status=4
was sent back as an indication of the GO Negotiation Request frame being
invalid. This response is not sent anymore and the status code for the
P2P-GO-NEG-FAILURE event is changed from 4 (invalid parameters) to 11
(rejected by user) for this specific workaround case.

If P2P was disabled (e.g., due to driver not supporting it or through
p2p_disabled=1 configuration), setting Wi-Fi Display parameters could
result in segmentation fault when the WFD IE is updated without the P2P
module being initialized. Fix this by skipping the update if P2P module
is not in use. In addition, show Wi-Fi Display as disabled in "GET
wifi_display" and refuse to enable it with "SET wifi_display 1" if P2P
is not enabled.

It is possible for the driver to report Beacon RX prior to hostapd
having completed AP mode setup, e.g., when changing country code. Beacon
frame processing for OLBC was not prepared for this and could trigger
segfault due to NULL pointer dereference. Fix this by ignoring the
Beacon frames received prior to completing interface setup when
determining OLBC updates.

Commit b1f625e0d8 extended
ap_scan_as_station to be able to distinguish between AP and P2P GO
iftypes. However, it did this in a way that completely lost the original
mode because drv->nlmode had already been replaced with the station
mode. Fix this by storing the correct old mode.

If the peer device has already acknowledge receipt of the Invitation
Request frame, it is better not to re-start invitation by sending
another Invitation Request. This should not be needed since the peer
already has received the Invitation Request frame and sending the second
round in this type of sequence can cause issues with nl80211 offloaded
offchannel TX operations since driver_nl80211.c will lose the cookie
value for the first pending Action frame and may not be able to cancel
offchannel wait for it properly. this has been seen to trigger a failure
in the p2p_go_invite_auth test case with the scan failing due to GO
sending out Probe Response frame on incorrect channel (the channel used
in that not-cancelled Action TX).

Commit bd3a373767 added a mechanism to use
AP Channel attribute from within a Credential attribute to optimize
scans. However, this design is not actually used with the WPS NFC use
cases. With configuration token, the AP Channel attribute is in the same
container with the Credential attribute (and that was also handled in
the previous implementation). With connection handover, AP Channel
information is outside the Credential attribute as well.
Simplify implementation by removing the AP Channel within Credential
case. This allows wpas_wps_use_cred() to get the AP Channel from the
container instead of having to find this during credential iteration.
