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

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.

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
the find operation after this.

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.

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.

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.

Commit 795baf773f ('hostapd: Filter
channel list updated events after country code change') uses the
EVENT_CHANNEL_LIST_CHANGED data pointer, but it updated only one of the
callers to provide that data. NL80211_CMD_REG_BEACON_HINT event was
still sending the event without the initiator data and resulted in NULL
pointer dereference, e.g., if a scan was run while hostapd was running
and the driver was in world roaming state and enabled a channel for
active scans.

Before this patch, 1 second timeout was used for regulatory updates. In
some cases, specially when we reload driver modules on some slower
platforms this could take more than 1 second (about 2 seconds). This is
important specially for DFS case, where we have to have correct DFS
region before we will start CAC. In other case (unknown DFS region), CAC
will fail. 5 seconds should be enough for all cases.

The original RSSI filter semantics for scheduled scan were
really confusing - a separate matchset was created, but it
wasn't actually treated as a separate matchset in the kernel
but rather used as the global RSSI value. The RSSI matchset
thus behaved like an RSSI filter outside of the matchsets,
being ANDed rather than ORed (as normal between matchsets.)
To make this less confusing, I changed the kernel API a bit
to actually treat the RSSI inside each matchset properly,
but keeping it compatible with the old approach by using a
matchset with only an RSSI value as the default for all the
other matchsets, and adding it as a separate matchset only
if it's the only one.
The proper way for wpa_supplicant to do this then would be
to add the RSSI to each SSID matchset, and only add another
matchset without SSID if there's none with.
However, to keep compatibility with older kernels, always
keep the non-SSID matchset and only add the RSSI to all the
other matchsets. This gets close to the desired behaviour,
the only difference would be that we shouldn't add the RSSI
matchset if there are others, but stays compatible with old
and new kernels, as new ones ignore the RSSI-only matchset
if there are others and those others have an RSSI.

This new mechanism allows P2P Client to request an IPv4 address from the
GO as part of the 4-way handshake to avoid use of DHCP exchange after
4-way handshake. If the new mechanism is used, the assigned IP address
is shown in the P2P-GROUP-STARTED event on the client side with
following new parameters: ip_addr, ip_mask, go_ip_addr. The assigned IP
address is included in the AP-STA-CONNECTED event on the GO side as a
new ip_addr parameter. The IP address is valid for the duration of the
association.
The IP address pool for this new mechanism is configured as global
wpa_supplicant configuration file parameters ip_addr_go, ip_addr_mask,
ip_addr_star, ip_addr_end. For example:
ip_addr_go=192.168.42.1
ip_addr_mask=255.255.255.0
ip_addr_start=192.168.42.2
ip_addr_end=192.168.42.100
DHCP mechanism is expected to be enabled at the same time to support P2P
Devices that do not use the new mechanism. The easiest way of managing
the IP addresses is by splitting the IP address range into two parts and
assign a separate range for wpa_supplicant and DHCP server.
