This case of accepting WPA/TKIP-only credential based on internal
registrar request to configure an AP to use TKIP was still remaining
while all the WPS cases were supposed to enable mixed mode

explicit local request to configure TKIP, but anyway, convert this one
as well to allow WPA2/CCMP to be used.

When wps_cred_add_sae=1 is used, WPS_AUTH_WPA2PSK credential gets
converted to enabling both PSK and SAE AKMs. However, this case was
still hardcoded auth_alg=OPEN which is not really correct for SAE. While
the SME-in-wpa_supplicant case can handle that, the SME-in-driver case
might not. Remove the unnecessary auth_alg=OPEN configuration to get the
normal PSK+SAE configuration enabled for the network profile.

While the WSC specification requires the Enrollee to stop PBC
provisioning if the scan sees multiple APs in active PBC mode, this is
problematic due to some deployed devices continuing to advertise PBC
mode for extended duration (or even permanently). Such an environment
will still need to prevent wildcard AP selection with PBC since an
incorrect device could be selected. However, if the Enrollee device has
been explicitly requested to connect to a specific AP based on its
BSSID, the other APs in scan results can be ignored without affecting
which AP would be selected (only the one matching the specified BSSID is
acceptable).
Start filtering scan results for PBC session overlap check based on the
locally specified constraint on the BSSID, if one is set. This allows
PBC to be used with "WPS_PBC <BSSID>" command in environment where
another AP device is claiming to be in active PBC mode while "WPS_PBC"
command will still continue to reject provisioning since the correct AP
cannot be selected.
This will also cover the P2P cases where P2P_CONNECT is used to start or
authorize GO Negotiation and joining-a-GO with a specific P2P GO
Interface Address (BSSID).

This allows a P2P connection over P802.11ay EDMG channels to achieve the
highest link speed that the standard allows for channel bonding (CB) up
to CB4.
Let each P2P peer add its EDMG channels to the Supported Channels IE
advertised in P2P GO negotiation. Give EDMG channels priority when peers
negotiate for operating channel.
User may add 'edmg' parameter to p2p_connect, p2p_add_group, and
p2p_invite commands to prefer an EDMG channel for the P2P link. User may
also set p2p_go_edmg=1 in wpa_supplicant configuration file to prefer
EDMG.
When EDMG is used, P2P will try to find the highest channel bonding
supported channel that matches the frequency parameter, if the devices
do not support EDMG, the P2P connection will use a legacy (1-6) 60 GHz

The Wi-Fi Alliance Multi-AP Specification v1.0 allows onboarding of a
backhaul STA through WPS. To enable this, the backhaul STA needs to add
a Multi-AP IE to the WFA vendor extension element in the WSC M1 message
that indicates it supports the Multi-AP backhaul STA role. The Registrar
(if it support Multi-AP onboarding) will respond to that with a WSC M8
message that also contains the Multi-AP IE, and that contains the
credentials for the backhaul SSID (which may be different from the SSID
on which WPS is performed).
Introduce a new parameter to wpas_wps_start_pbc() and allow it to be
set via control interface's new multi_ap=1 parameter of WPS_PBC call.
multi_ap_backhaul_sta is set to 1 in the automatically created SSID.
Thus, if the AP does not support Multi-AP, association will fail and
WPS will be terminated.
Only wps_pbc is supported.
This commit adds the multi_ap argument only to the control socket
interface, not to the D-Bus interface.
Since WPS associates with the fronthaul BSS instead of the backhaul BSS,
we should not drop association if the AP announces fronthaul-only BSS.
Still, we should only do that in the specific case of WPS. Therefore,
add a check to multi_ap_process_assoc_resp() to allow association with a
fronthaul-only BSS if and only if key_mgmt contains WPS.

In many places in the code there was a reference to wpa_s->parent to get
from group interface to p2p_dev interface. These places can break if
P2P_DEVICE interface would need to be used with the primary interface as
the group interface, since the parent of the primary interface points to
itself and not the p2p_dev interface.
Fix this by adding a separate "p2pdev" pointer to wpa_supplicant,
it will be the same as parent pointer in most cases but whenever
the primary interface is used as a group interface, change it to
point to the correct p2p_dev interface.

PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
PBSS support is mandatory for IEEE 802.11ad devices.
Add a new "pbss" argument to network block. The argument is used
in the following scenarios:
1. When network has mode=2 (AP), when pbss flag is set will start
as a PCP instead of an AP.
2. When network has mode=0 (station), when pbss flag is set will
connect to PCP instead of AP.
The function wpa_scan_res_match() was modified to match BSS according to
the pbss flag in the network block (wpa_ssid structure). When pbss flag
is set it will match only PCPs, and when it is clear it will match only
APs.

shall stop.

PBC overlap detection searches for another BSS with active PBC in the
BSS table. However, when a separate P2P interface is used, scan results
without P2P IE are not saved in the BSS table, so non-P2P BSS's with
active PBC will not be detected.
Fix this by iterating only the WPS AP array instead of the BSS table.
This is also more efficient since only WPS APs may have active PBC. This
also fixes hwsim test "grpform_pbc_overlap" when a dedicated P2P Device

Previously, wpa_supplicant was using number of scan iterations
(WPS_PIN_SCAN_IGNORE_SEL_REG = 3) to give some time for finding a WPS AP
with Selected Registrar TRUE before starting to iterate through all WPS
APs. While this works fine in most cases, some drivers may return the
initial three scan results so quickly that the total amount of time is
only couple of seconds in case none of the APs are initially advertising
Selected Registrar TRUE. To give some more time for APs (WPS Registrars)
to become ready, add an additional constraint on the iteration based on
time (WPS_PIN_TIME_IGNORE_SEL_REG = 5 seconds).
