Add "persistent=<network id>" line to P2P_PEER ctrl_iface data
if a persistent group credentials are available for this peer.
This makes it easier for external programs to figure out when
a persistent group could be re-invoked with this peer.
For now, this information is only available on the P2P client,
but similar information can be added for GO once a list of P2P
clients is maintained with the persistent group data.

The P2P module provides access to public peer data in struct
p2p_peer_info. Use this to build the P2P_PEER information in
ctrl_iface.c instead of providing such text format data from the P2P
module.
The internal data that was previously built in p2p_get_peer_info() as
part of the text format peer data is now available through a separate
p2p_get_peer_info_txt() function. This is still included in P2P_PEER
output to maintain backwards compatibility with external programs that
could have started to use this. However, it should be noted that this
data is not really supposed to be used for anything else apart from
debugging purposes and its format is subject to change.

The whole wpa_supplicant_ctrl_iface_ctrl_rsp_handle() function operates

Convert core wpa_supplicant code to use u64 instead of void * for the
P2P service discovery reference. Use uintptr_t in type casts in
p2p_supplicant.c to handle the conversion without warnings.
Note: This needs to be revisited for 128-bit CPU where sizeof(void *)
could be larger than sizeof(u64).

When normal scan can speed up operations, use that for the first three

We do this only if the normal scan has functionality that is suitable

This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.
Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.
New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.
The P2P specification (3.1.4.3) disallows use of the Label configuration
method between two P2P devices. This was previously enforced at upper
level, but the obsolete code can be removed from wpa_supplicant. This
adds a bit more strict enforcement of the policy, but should not result
in practical differences since no known P2P implementation uses Label
config method.
If a network configuration block is removed or modified, flush
all PMKSA cache entries that were created using that network
configuration. Similarly, invalidate EAP state (fast re-auth).
The special case for OKC on wpa_supplicant reconfiguration
(network_ctx pointer change) is now addressed as part of the
PMKSA cache flushing, so it does not need a separate mechanism
for clearing the network_ctx values in the PMKSA cache.
Make sure that the WPA and EAPOL state machines do not hold a pointer
to a network configuration that is about to be freed. This can fix
potential issues with references to freed memory.
It is now possible to configure the the time in seconds that
wpa_supplicant waits before requesting a new scan after failing to find
a suitable network in scan results.

Replace compile-time BSS cache expiration age and scan count by config
parameters that can be set via wpa_cli and the new D-Bus API. The latter
is done with interface properties BSSExpireAge and BSSExpireCount.
Use a specific return value, WPS-PBC-OVERLAP, to indicate a reason
for rejecting a wps_pbc command in wpa_supplicant AP mode if the
PBC mode cannot be started due to PBC session overlap having been
detected during monitor time.
If there is already a link the requested peer, request start of
renegotiation instead of completely new link. This seems to be needed
to allow some driver to accept the trigger for a new negotiation.
These special test cases can be configured at run time with "wpa_cli
tdls_testing <value>" where <value> is an integer (either as a decimal
or as a hex value with 0x prefix) bitmap of special features with
following bits available at this point:
bit 0 = long frame (add dummy subelement to make FTIE very long)
bit 1 = use alternative RSN IE (different RSN capab value and no extra
replay counters)
bit 2 = send incorrect BSSID in Link Identifier of TDLS Setup Request
(e.g., 1 = long FTIE, 2 = different RSN IE, 3 = both of those)
This is disabled by default and can be enabled for the build by
adding the following line to .config:
CFLAGS += -DCONFIG_TDLS_TESTING
Previous code was assuming that the P2P module is always initialized.
However, that is not the case anymore with drivers that do not support
P2P. Add verification of whether P2P is enabled before trying to execute
P2P commands.
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".
I tried these commands:
./wpa_cli -i wlan0 p2p_group_add
./wpa_cli -i wlan0 p2p_find
The second one results in following messages because it is invalid
operation.
-------
nl80211: Scan trigger failed: ret=-95 (Operation not supported)
P2P: Failed to start p2p_scan
-------
But the second one shows "OK" on control console.
This patch makes it to show "FAIL".
Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).
The destination address for p2p_serv_disc_resp must always be set
to an individual MAC address unlike p2p_serv_disc_req which may use
00:00:00:00:00:00 to indicate wildcard query. As such, we should not
try to check for this special case here.
Replacing the BSSID with 'any' has never worked with wps_reg
command, so better not claim it could work. In addition, reject
this is wpa_supplicant to make it clearer that the operation
fails.
This command can be used to enroll a network based on a local
network configuration block instead of having to (re-)learn the
current AP settings with wps_er_learn.
The driver wrapper can now indicate whether the driver supports
concurrent operations on multiple channels (e.g., infra STA connection
on 5 GHz channel 36 and P2P group on 2.4 GHz channel 1). If not,
P2P_CONNECT commands will be rejected if they would require
multi-channel concurrency.
The new failure codes for P2P_CONNECT:
FAIL-CHANNEL-UNAVAILABLE:
The requested/needed channel is not currently available (i.e., user has
an option of disconnecting another interface to make the channel
available).
FAIL-CHANNEL-UNSUPPORTED:
The request channel is not available for P2P.
This cleans up debug log from unnecessary entries when using
wpa_cli/hostapd_cli or other ctrl_iface monitors that PING
periodically to check connectivity.
Instead of build time options (CONFIG_WPS_TESTING_EXTRA_CRED and
CONFIG_WPS_EXTENSIBILITY_TESTING), use a single build option
(CONFIG_WPS_TESTING) and runtime configuration of which testing
operations are enabled. This allows a single binary to be used
for various tests.
The runtime configuration can be done through control interface
with wpa_cli/hostapd_cli commands:
Enable extensibility tests:
set wps_version_number 0x57
Disable extensibility tests (WPS2 build):
set wps_version_number 0x20
Enable extra credential tests:
set wps_testing_dummy_cred 1
Disable extra credential tests:
set wps_testing_dummy_cred 0
ctrl_interface STA_AUTOCONNECT command can now be used to disable
automatic reconnection on receiving disconnection event. The default
behavior is for wpa_supplicant to try to reconnect automatically, i.e.,
to maintain previous behavior.
A new ctrl_interface command, WPS_CANCEL, can now be used to cancel
a pending or ongoing WPS operation. For now, this is only available
with wpa_supplicant (either in station or AP mode). Similar
functionality should be added for hostapd, too.
This is needed to be able to change parameters for dynamically
created interfaces between the creation of the interface and
association/start AP commands.
Following ctrl_interface commands can now be used:
P2P_SET client_apsd disable
- disable configuration (i.e., use driver default) in client mode
P2P_SET client_apsd <BE>,<BK>,<VI>,<VO>;<max SP Length>
- enable UASPD with specific trigger configuration (0/1) per AC
(max SP Length is currently ignored)
P2P_SET go_apsd disable
- disable configuration (i.e., use driver default) in AP mode
P2P_SET go_apsd <0/1>
- disable/enable APSD in AP mode
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.
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.
"wpa_cli p2p_set peer_filter <MAC address>" can now be used to
only allow a single P2P Device (based on P2P Device Address) to be
discovered for testing. Setting the address to 00:00:00:00:00:00
disables the filter.
This is mainly designed for testing and allows p2p_connect join auth
to be used to accept a specific invitation to an active group that
may be received in the future.
Advertize list of authorized enrollee MAC addresses in Beacon and
Probe Response frames and use these when selecting the AP. In order
to provide the list, the enrollee MAC address should be specified
whenever adding a new PIN. In addition, add UUID-R into
SetSelectedRegistrar action to make it potentially easier for an AP
to figure out which ER sent the action should there be multiple ERs
using the same IP address.
wps_er_config can now be used to configure an AP. It is similar to
wps_er_learn, but instead of only learning the current AP settings,
it continues to send M8 with the new settings for the AP.
wps_er_start command now takes an optional parameter that can be used
to configure a filter to only allow UPnP SSDP messages from the
specified IP address. In practice, this limits the WPS ER operations
to a single AP and filters out all other devices in the network.
Add a new wpa_supplicant state: interface disabled. This can be used
to allow wpa_supplicant to be running with the network interface even
when the driver does not actually allow any radio operations (e.g.,
due to rfkill).
Allow driver_nl80211.c and driver_wext.c to start while rfkill is in
blocked state (i.e., when ifconfig up fails) and process rfkill
events to block/unblock WLAN.
'wpa_cli roam <bssid>' can now be used to test roaming within an ESS
(e.g., for FT over-the-air). This command will bypass a new scan and
will select the BSS based on the specified BSSID. It is responsibility
of the caller to make sure that the target AP is in the BSS table.
This can be done, e.g., by running a scan before the roam command,
if needed.
This sets the FT Capability and Policy field in the MDIE to the values
received from the target AP (if available). This fixes the MDIE contents
during FT Protocol, but the correct value may not yet be used in initial
mobility domain association.
Despite comments in the wpa_config_update_prio_list(struct wpa_config
*config) telling that it is called "if priority for a network is
changed", it is apparently not.

wpa_supplicant can now be notified of suspend/resume events, e.g.,
from pm-action scripts. This allows wpa_supplicant to clear information
that may become invalid during a suspend operation.
This fits better in wpa_supplicant/scan.c. Couple of remaining
scan_helpers.c functions are currently used in driver wrappers,
but they can likely be removed in the future.
Get more information about scans when updating BSS table information.
This allows the missing-from-scans expiration rule to work properly
when only partial set of channels or SSIDs are being scanned.
In addition, provide another option for iterating through the BSS
entries. The old iteration: "BSS 0", "BSS 1", .. with index number.
The new iteration: "BSS FIRST", "BSS NEXT-<prev id>", .. with id
fetched from the previous output (id=<id> line).
Instead of forcefully deinitializing ER immediately, give it some
time to complete unsubscription and call eloop_terminate() only once
ER code has completed its work.
