During persistent group re-invocation, GO may end up using a different
channel as the operation channel compared to what was indicated in the
invitation frames. This may break the connection if the peer device ends
up scanning the GO only on the channel from the invitation frame. Fix
this by using the negotiated channel (if available) on the GO as the
operating channel instead of the channel that was provided in the
p2p_invite command to start negotiation.

There are use cases requesting the host driver to initiate the TDLS
setup with the peer only when configured by the external applications.
Thus, enable this control by tdls_external_control=1 and pass the
requisite information for the specific TDLS operation to the driver
on the request from such use cases.
This operation mode expects the driver to initiate TDLS link
automatically based on signal strength and traffic to a peer and tear
down links whenever they are not used or suitable due to signal strength
etc. The list of peers with which such operations are to be performed
are provided with the TDLS driver operations.

This is a better way of matching P2P groups based on the unique P2P

If a BSS is disallowed temporarily with disallow_aps, the network
connection is going to fail. As such, there is not much point in
allowing Interworking network selection to try to connect with such BSS.
As such, do not consider disallowed networks for automatic network
selection and reject requests to connect to them through
INTERWORKING_CONNECT.

Do not add multiple network blocks for the same network from a single
credential. INTERWORKING_CONNECT used to generate a new network block
for each instance regardless of what network blocks have already been
configured. While this allows the connection to go through, it is not
efficient to leave behind potentially large number of network blocks
with the same contents (or worse, changed contents). Address this by
removing an older network block for the same credential before adding a
new one.

If we are already connected to the selected AP with a network block

Number of regressions had shown up in wpa_supplicant implementation of
SAE group selection due to different integer array termination (-1 in
hostapd, 0 in wpa_supplicant) being used for SAE groups. The
default_groups list did not seem to use any explicit termination value.
In addition, the sae_group_index was not cleared back to 0 properly
whenever a new SAE session was started.

It was possible for the wpa_s->show_group_started and wpa_s->go_params
to be left set when a P2P group was removed before group formation had
completed. In case a separate P2P group interface was not used, this
could rsult in all future scans using the hardcoded DIRECT-* SSID and as
such, not find the network they were trying to find. Fix this by
clearing these P2P parameters on group removal.

wpas_p2p_setup_channels function uses the per interface information
(wpa_s->hw.modes) for setting up the available channel list for P2P
operation, but if a separate P2P interface is used (e.g., p2p0 on
Android), the wpa_s instance for that interface may not get an updated
channel list. This can result in some operations, like "P2P_SET
disallow_freq", using old channel list information (e.g., world roaming
information with passive-scan/no-ibss flags) which was initialized
during the start-up. This could result in P2P functionality using
conflicting or obsolete channel information.
To resolve this issue, update channel list information on regulatory
change events to all of the virtual interfaces sharing the same phy for
which the event is received.

Commit ca9bc5b566 added wpas_conf_ap_vht()

Both of these variables can result in optimized WPS scans, so better

Make sure special optimized scans (like WPS-single-channel or

The new p2p_add_cli_chan=1 configuration parameter can be used to
request passive-scan channels to be included in P2P channel lists for
cases where the local end may become the P2P client in a group. This

device is not aware of its current location and has marked most channels
to require passive scanning.

The new p2p_no_go_freq frequency range list (comma-separated list of
min-max frequency ranges in MHz) can now be used to configure channels
on which the local device is not allowed to operate as a GO, but on
which that device can be a P2P Client. These channels are left in the
P2P Channel List in GO Negotiation to allow the peer device to select
one of the channels for the cases where the peer becomes the GO. The
local end will remove these channels from consideration if it becomes
the GO.
