Previously, any network block could be used to select the BSS to connect
to when processing scan results after Interworking network selection.
This can result in somewhat unexpected network selection in cases where
credential preferences indicated that a specific network was selected,
but another network ended up getting used for the connection. While the
older networks continue to be valid, add special processing for this
initial post-interworking-connect case to get more consistent network
selection to match with the Interworking network selection result.

It was possible for the connect or sme-connect radio work to get
re-scheduled while an earlier request was still pending, e.g.,
select_network is issued at the moment a scan radio work is in progress
and the old scan results are recent enough for starting the connection.
This could result in unexpected attempt to re-associate immediately
after completing the first connection.

While testing rfkill blocking of a scanning interface, it
was seen that the ongoing scan never completes. This happens
since EVENT_SCAN_RESULTS is discarded on a disabled interface.
Fix this and also other possible radio work completion issues
by removing all the radio works (including started) of the
disabled interface.
To be able to remove already started radio works, make their
callbacks be reentrant with deinit flag (when the work
is started), so each radio work should be able to handle
its own termination.

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.

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.

This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such

formed on different channels.
If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed

When start PNO request comes from control interface, wpa_supplicant
should wait until ongoing sched_scan (triggered by wpa_supplicant)
gets cancelled. Issuing cancel sched_scan and start PNO scan
one after another from pno_start() would lead wpa_supplicant to clear
wps->sched_scanning flag while getting sched_scan stopped event
from driver for cancel sched_scan request. In fact, PNO scan will
be in progress in driver and wpa_s->sched_scanning will not be set
in such cases.
In addition to this change, RSSI threshold limit is passed as part of

It is possible for the GO of a persistent group to change the PSK or
remove a client when per-client PSKs are used and this can happen
without the SSID changing (i.e., the group is still valid, but just not
for a specific client). If the client side of such persistent group ends
up trying to use an invalidated persistent group information, the
connection will fail in 4-way handshake. A new WPS provisioning step is
needed to recover from this.
Detect this type of case based on two 4-way handshake failures when
acting as a P2P client in a persistent group. A new
"P2P-PERSISTENT-PSK-FAIL id=<persistent group id>" event is used to
indicate when this happens. This makes it easier for upper layers to
remove the persistent group information with "REMOVE_NETWORK <persistent
group id>" if desired (e.g., based on user confirmation).
In addition to indicating the error cases for persistent groups, all

Since wired IEEE 802.1X do not have BSSID, make this additional

This fixes issues where the initial EAPOL frame after reassociation was

SSID_SPEC ::= ssid <SSID_HEX>
BSSID_SPEC ::= bssid <BSSID_HEX>
For example:
wpa_cli set disallow_list "ssid 74657374 bssid 001122334455 ssid 68656c6c6f"
wpa_cli set disallow_list
(the empty value removes all entries)

Since we have a global P2P module, the flag to trigger scan completion
events to it needs to be in similar context. The previous design
maintained this separately for each virtual interface and if P2P module
did not run its scan operation on the virtual interface that completed
the scan, P2P module would not be allowed to restart operations
properly.

Use configured credentials to figure out which ANQP information needs to
be fetched and only fetch those when using Interworking network
selection. The fetch_anqp command is still fetching all ANQP
information.

If the scan results from before ANQP fetch are fresh (less than five
seconds old), do not run a new scan when selecting the BSS after having
used Interworking network selection.

This allows last results to be used even after they have been freed
since the information is copied to the BSS entries anyway and this new
array provides the order in which scan results were processed.

The freq and ht40 parameters can now be used with the p2p_invite
command when reinvoking a persistent group as the GO.

This commit adds control interface commands and internal storage of
Wi-Fi Display related configuration. In addition, WFD IE is now added
to various P2P frames, Probe Request/Response, and (Re)Association
Request/Response frames. WFD subelements from peers are stored in the
P2P peer table.
Following control interface commands are now available:
SET wifi_display <0/1>
GET wifi_display
WFD_SUBELEM_SET <subelem> [hexdump of length+body]
WFD_SUBELEM_GET <subelem>

auto_interworking=1 configuration parameter can be used to request
wpa_supplicant to use Interworking network selection automatically as a
part of the normal (non-Interworking) network selection if the scan
results do not match with enabled networks. This makes scanning work
similarly to the "interworking_select auto" command.
