8fd7dc1b1c P2P: Add new_device flag to dev_found callback
The DBus code will want to have perfect matching of dev_found and the
dev_lost it adds so it doesn't need to keep track internally. Enable
that with a new flag in the core that tracks whether we have already
notified about this -- the existing users can ignore it.

The part where this is always set to 1 if the new device is discovered
by a driver that has P2P in the driver is buggy -- the driver should
feed the P2P peer database and then that should feed the notification
here instead.

d601247ca9 P2P: Allow WPS_PBC command on GO to select on P2P Device Address
An optional parameter, p2p_dev_addr, can now be given to WPS_PBC
command on P2P GO to indicate that only the P2P device with the
specified P2P Device Address is allowed to connect using PBC. If
any other device tries to use PBC, a session overlap is indicated
and the negotiation is rejected with M2D. The command format for
specifying the address is "WPS_PBC p2p_dev_addr=<address>", e.g.,
WPS_PBC p2p_dev_addr=02:03:04:05:06:07

In addition, show the PBC session overlap indication as a WPS failure
event on an AP/GO interface. This particular new case shows up as
"WPS-FAIL msg=4 config_error=12".

0, those were used instead to try to set up a persistent group

If the GO is not found, we cannot send Provisioning Discovery Request
frame and cannot really connect anyway. Since the Provisioning
Discovery is a mandatory part, it is better to continue join-scan
until the GO is found instead of moving to the next step where
normal connection scan is used (PD would not be used from there).

Use a limit of 10 scan attempts for p2p_connect join to avoid getting
in infinite loop trying to join. If the GO is not found with those
scans, indicate failure (P2P-GROUP-FORMATION-FAILURE) and stop the
join attempt.

on current channel conditions.

This is needed to work around cases where the pending interface gets
removed, e.g., due to failed GO Negotiation. In such case, we may still
accept new GO Negotiation to be completed, but the interface did not
get created without a separate p2p_connect command.

The current implementation is not ideal since the re-created interface
may, at least in theory, get incorrect interface addrees. Though, this
would likely require that the driver supported more than one P2P group
interface and that the previous one was already taken into use for
another group.

This adds some more time for WPS provisioning step in case the peer
takes long time to start group interface operations.

SSID from GO Negotiation to select the AP.

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.

10b9ac17cf P2P: For now, do not use channels 12-14 in P2P groups
This is needed to make sure we do not try to accidentally enable GO
in channels that may not be allowed. In addition, this may help with
some driver that do not like channel 14 even as a passive scan
channel.

3dfda83d9c P2P: Add Device Password ID to GO Neg Request RX event

to use in GO Negotiation. For example:

72044390f3 P2P: Add support for cross connection
If enabled, cross connection allows GO to forward IPv4 packets
using masquerading NAT from the P2P clients in the group to an
uplink WLAN connection. This is disabled by default and can be
enabled with "wpa_cli p2p_set cross_connect 1" on the P2P device
interface.

aefb53bd5d P2P: Disable periodic NoA when non-P2P STA is connected
For now, this applies to the test command that can be used to set
periodic NoA (p2p_set noa). The value are stored and periodic NoA
is enabled whenever there are no non-P2P STAs connected to the GO.

4c08c0bd57 P2P: Include P2P IE in (Re)AssocReq to infra AP if it uses P2P IE
While this is not strictly speaking required by the P2P specification
for a not-P2P Managed Device, this can provide useful information for
the P2P manager AP and may be needed to pass certification tests.

131cb37c2d P2P: Allow pre-authorization of invitation to apply to src addr
For client-invites-device case, the pre-authorization of an invitation
to running group will need to allow Invitation Request from specified
address, too. This is for testing uses only.

108def931e P2P: Add command for pre-authorizing an invitation to an active group

to be used to accept a specific invitation to an active group that
may be received in the future.

07a30a66c3 P2P: Do not schedule new remain-on-channel if waiting for drv event
The driver event for remain-on-channel may be delayed in a way that
allows management-frame-received event to be received before
wpa_supplicant knows that the driver is actually already on the
previously requested channel. We should not request a new
remain-on-channel to send a response to just a frame if we are waiting
for the driver to get to the same channel. Instead, just continue
waiting for the driver event.

d6ae995057 P2P: Fix infinite loop on interface selection for Action frame TX
When the first wpa_supplicant interface is not the correct one for
transmitting an Action frame (e.g., P2P Presence Request frame
uses a group interface), the code got stuck in an infinite busy
loop. Fix the iteration to go through the interfaces properly.
