\page ctrl_iface_page %wpa_supplicant control interface
%wpa_supplicant implements a control interface that can be used by
external programs to control the operations of the %wpa_supplicant
daemon and to get status information and event notifications. There is
a small C library, in a form of a single C file, wpa_ctrl.c, that
provides helper functions to facilitate the use of the control
interface. External programs can link this file into them and then use
the library functions documented in wpa_ctrl.h to interact with
%wpa_supplicant. This library can also be used with C++. wpa_cli.c and
wpa_gui are example programs using this library.
There are multiple mechanisms for inter-process communication. For
example, Linux version of %wpa_supplicant is using UNIX domain sockets
for the control interface and Windows version UDP sockets. The use of
the functions defined in wpa_ctrl.h can be used to hide the details of
the used IPC from external programs.
\section using_ctrl_iface Using the control interface
External programs, e.g., a GUI or a configuration utility, that need to
communicate with %wpa_supplicant should link in wpa_ctrl.c. This
allows them to use helper functions to open connection to the control
interface with wpa_ctrl_open() and to send commands with
wpa_ctrl_request().
%wpa_supplicant uses the control interface for two types of communication:
commands and unsolicited event messages. Commands are a pair of
messages, a request from the external program and a response from
%wpa_supplicant. These can be executed using wpa_ctrl_request().
Unsolicited event messages are sent by %wpa_supplicant to the control
interface connection without specific request from the external program
for receiving each message. However, the external program needs to
attach to the control interface with wpa_ctrl_attach() to receive these
unsolicited messages.
If the control interface connection is used both for commands and
unsolicited event messages, there is potential for receiving an
unsolicited message between the command request and response.
wpa_ctrl_request() caller will need to supply a callback, msg_cb,
for processing these messages. Often it is easier to open two
control interface connections by calling wpa_ctrl_open() twice and
then use one of the connections for commands and the other one for
unsolicited messages. This way command request/response pairs will
not be broken by unsolicited messages. wpa_cli is an example of how
to use only one connection for both purposes and wpa_gui demonstrates
how to use two separate connections.
Once the control interface connection is not needed anymore, it should
be closed by calling wpa_ctrl_close(). If the connection was used for
unsolicited event messages, it should be first detached by calling
wpa_ctrl_detach().
\section ctrl_iface_cmds Control interface commands
Following commands can be used with wpa_ctrl_request():
\subsection ctrl_iface_PING PING
This command can be used to test whether %wpa_supplicant is replying
to the control interface commands. The expected reply is \c PONG if the
connection is open and %wpa_supplicant is processing commands.

\subsection ctrl_iface_BSS BSS
Get detailed per-BSS scan results. \c BSS command can be used to
iterate through scan results one BSS at a time and to fetch all
information from the found BSSes. This provides access to the same
data that is available through \c SCAN_RESULTS but in a way that
avoids problems with large number of scan results not fitting in the
ctrl_iface messages.
There are two options for selecting the BSS with the \c BSS command:
"BSS <idx>" requests information for the BSS identified by the index
(0 .. size-1) in the scan results table and "BSS <BSSID>" requests
information for the given BSS (based on BSSID in 00:01:02:03:04:05
format).
BSS information is presented in following format. Please note that new
fields may be added to this field=value data, so the ctrl_iface user
should be prepared to ignore values it does not understand.

\c LIST_NETWORKS command output.
This command uses the same variables and data formats as the
configuration file. See example wpa_supplicant.conf for more details.
- ssid (network name, SSID)
- psk (WPA passphrase or pre-shared key)
- key_mgmt (key management protocol)
- identity (EAP identity)
- password (EAP password)
- ...
\subsection ctrl_iface_GET_NETWORK GET_NETWORK <network id> <variable>
Get network variables. Network id can be received from the
\c LIST_NETWORKS command output.
\subsection ctrl_iface_SAVE_CONFIG SAVE_CONFIG
Save the current configuration.
\subsection ctrl_iface_P2P_FIND P2P_FIND
Start P2P device discovery. Optional parameter can be used to specify
the duration for the discovery in seconds (e.g., "P2P_FIND 5"). If the
duration is not specified, discovery will be started for indefinite
time, i.e., until it is terminated by P2P_STOP_FIND or P2P_CONNECT (to
start group formation with a discovered peer).
The default search type is to first run a full scan of all channels
and then continue scanning only social channels (1, 6, 11). This
behavior can be changed by specifying a different search type: social
(e.g., "P2P_FIND 5 type=social") will skip the initial full scan and
only search social channels; progressive (e.g., "P2P_FIND
type=progressive") starts with a full scan and then searches
progressively through all channels one channel at the time with the
social channel scans. Progressive device discovery can be used to find
new groups (and groups that were not found during the initial scan,
e.g., due to the GO being asleep) over time without adding
considerable extra delay for every Search state round.
\subsection ctrl_iface_P2P_STOP_FIND P2P_STOP_FIND
Stop ongoing P2P device discovery or other operation (connect, listen
mode).
\subsection ctrl_iface_P2P_CONNECT P2P_CONNECT
Start P2P group formation with a discovered P2P peer. This includes
group owner negotiation, group interface setup, provisioning, and
establishing data connection.
P2P_CONNECT <peer device address> <pbc|pin|PIN#>
[label|display|keypad] [persistent] [join|auth] [go_intent=<0..15>]
Start P2P group formation with a discovered P2P peer. This includes
optional group owner negotiation, group interface setup, provisioning,
and establishing data connection.
The <pbc|pin|PIN#> parameter specifies the WPS provisioning
method. "pbc" string starts pushbutton method, "pin" string start PIN
method using an automatically generated PIN (which will be returned as
the command return code), PIN# means that a pre-selected PIN can be
used (e.g., 12345670). [label|display|keypad] is used with PIN method
to specify which PIN is used (label=PIN from local label,
display=dynamically generated random PIN from local display,
keypad=PIN entered from peer device label or display). "persistent"
parameter can be used to request a persistent group to be formed.
"join" indicates that this is a command to join an existing group as a
client. It skips the GO Negotiation part.
"auth" indicates that the WPS parameters are authorized for the peer
device without actually starting GO Negotiation (i.e., the peer is
expected to initiate GO Negotiation). This is mainly for testing
purposes.
The optional "go_intent" parameter can be used to override the default
GO Intent value.
\subsection ctrl_iface_P2P_LISTEN P2P_LISTEN
Start Listen-only state. Optional parameter can be used to specify the
duration for the Listen operation in seconds. This command may not
be of that much use during normal operations and is mainly designed
for testing. It can also be used to keep the device discoverable
without having to maintain a group.
\subsection ctrl_iface_P2P_GROUP_REMOVE P2P_GROUP_REMOVE
Terminate a P2P group. If a new virtual network interface was used for
the group, it will also be removed. The network interface name of the
group interface is used as a parameter for this command.
\subsection ctrl_iface_P2P_GROUP_ADD P2P_GROUP_ADD
Set up a P2P group owner manually (i.e., without group owner
negotiation with a specific peer). This is also known as autonomous
GO. Optional persistent=<network id> can be used to specify restart of
a persistent group.
\subsection ctrl_iface_P2P_PROV_DISC P2P_PROV_DISC
Send P2P provision discovery request to the specified peer. The
parameters for this command are the P2P device address of the peer and
the desired configuration method. For example, "P2P_PROV_DISC
02:01:02:03:04:05 display" would request the peer to display a PIN for
us and "P2P_PROV_DISC 02:01:02:03:04:05 keypad" would request the peer
to enter a PIN that we display.
\subsection ctrl_iface_P2P_GET_PASSPHRASE P2P_GET_PASSPHRASE
Get the passphrase for a group (only available when acting as a GO).
\subsection ctrl_iface_P2P_SERV_DISC_REQ P2P_SERV_DISC_REQ
Schedule a P2P service discovery request. The parameters for this
command are the device address of the peer device (or 00:00:00:00:00:00
for wildcard query that is sent to every discovered P2P peer that
supports service discovery) and P2P Service Query TLV(s) as hexdump.
For example, "P2P_SERV_DISC_REQ 00:00:00:00:00:00 02000001" schedules
a request for listing all supported service discovery protocols and
requests this to be sent to all discovered peers. The pending requests
are sent during device discovery (see \ref ctrl_iface_P2P_FIND).
This command returns an identifier for the pending query (e.g.,
"1f77628") that can be used to cancel the request. Directed requests
will be automatically removed when the specified peer has replied to
it.
\subsection ctrl_iface_P2P_SERV_DISC_CANCEL_REQ P2P_SERV_DISC_CANCEL_REQ
Cancel a pending P2P service discovery request. This command takes a
single parameter: identifier for the pending query (the value returned
by \ref ctrl_iface_P2P_SERV_DISC_REQ), e.g.,
"P2P_SERV_DISC_CANCEL_REQ 1f77628".
\subsection ctrl_iface_P2P_SERV_DISC_RESP P2P_SERV_DISC_RESP
Reply to a service discovery query. This command takes following
parameters: frequency in MHz, destination address, dialog token,
response TLV(s). The first three parameters are copied from the
request event. For example,
"P2P_SERV_DISC_RESP 2437 02:40:61:c2:f3:b7 1 0300000101".
\subsection ctrl_iface_P2P_SERVICE_UPDATE P2P_SERVICE_UPDATE
Indicate that local services have changed. This is used to increment
the P2P service indicator value so that peers know when previously
cached information may have changed.
\subsection ctrl_iface_P2P_SERV_DISC_EXTERNAL P2P_SERV_DISC_EXTERNAL
Configure external processing of P2P service requests: 0 (default) =
no external processing of requests (i.e., internal code will reject
each request), 1 = external processing of requests (external program
is responsible for replying to service discovery requests with
\ref ctrl_iface_P2P_SERV_DISC_RESP).
\subsection ctrl_iface_P2P_REJECT P2P_REJECT
Reject connection attempt from a peer (specified with a device
address). This is a mechanism to reject a pending GO Negotiation with
a peer and request to automatically block any further connection or
discovery of the peer.
\subsection ctrl_iface_P2P_INVITE P2P_INVITE
Invite a peer to join a group or to (re)start a persistent group.
\subsection ctrl_iface_P2P_PEER P2P_PEER
Fetch information about a discovered peer. This command takes in an
argument specifying which peer to select: P2P Device Address of the
peer, "FIRST" to indicate the first peer in the list, or "NEXT-<P2P
Device Address>" to indicate the entry following the specified peer
(to allow for iterating through the list).
\subsection ctrl_iface_P2P_EXT_LISTEN P2P_EXT_LISTEN
Enable/disable extended listen timing. Without parameters, this
command disables extended listen timing. When enabling the feature,
two parameters are used: availibility period and availability interval
(both in milliseconds and with range of 1-65535).
\section ctrl_iface_interactive Interactive requests
If %wpa_supplicant needs additional information during authentication
(e.g., password), it will use a specific prefix, \c CTRL-REQ-
(\a WPA_CTRL_REQ macro) in an unsolicited event message. An external
program, e.g., a GUI, can provide such information by using
\c CTRL-RSP- (\a WPA_CTRL_RSP macro) prefix in a command with matching
field name.
The following fields can be requested in this way from the user:
- IDENTITY (EAP identity/user name)
- PASSWORD (EAP password)
- NEW_PASSWORD (New password if the server is requesting password change)
- PIN (PIN code for accessing a SIM or smartcard)
- OTP (one-time password; like password, but the value is used only once)
- PASSPHRASE (passphrase for a private key file)
\verbatim
CTRL-REQ-<field name>-<network id>-<human readable text>
CTRL-RSP-<field name>-<network id>-<value>
\endverbatim
For example, request from %wpa_supplicant:
\verbatim
CTRL-REQ-PASSWORD-1-Password needed for SSID test-network
\endverbatim
And a matching reply from the GUI:
\verbatim
CTRL-RSP-PASSWORD-1-secret
\endverbatim
\subsection ctrl_iface_GET_CAPABILITY GET_CAPABILITY <option> [strict]
Get list of supported functionality (eap, pairwise, group,
proto). Supported functionality is shown as space separate lists of
values used in the same format as in %wpa_supplicant configuration.
If optional argument, 'strict', is added, only the values that the
driver claims to explicitly support are included. Without this, all
available capabilities are included if the driver does not provide
a mechanism for querying capabilities.
Example request/reply pairs:
\verbatim
GET_CAPABILITY eap
AKA FAST GTC LEAP MD5 MSCHAPV2 OTP PAX PEAP PSK SIM TLS TTLS
\endverbatim
\verbatim
GET_CAPABILITY pairwise
CCMP TKIP NONE
\endverbatim
\verbatim

\verbatim
GET_CAPABILITY auth_alg
OPEN SHARED LEAP
\endverbatim
\subsection ctrl_iface_AP_SCAN AP_SCAN <ap_scan value>
Change ap_scan value:
0 = no scanning,
1 = %wpa_supplicant requests scans and uses scan results to select the AP,
2 = %wpa_supplicant does not use scanning and just requests driver to
associate and take care of AP selection
\subsection ctrl_iface_INTERFACES INTERFACES
List configured interfaces.
\verbatim

\endverbatim
\section ctrl_iface_events Control interface events
%wpa_supplicant generates number messages based on events like
connection or a completion of a task. These are available to external
programs that attach to receive unsolicited messages over the control
interface with wpa_ctrl_attach().
The event messages will be delivered over the attach control interface
as text strings that start with the priority level of the message and
a fixed prefix text as defined in wpa_ctrl.h. After this, optional
additional information may be included depending on the event
message. For example, following event message is delivered when new
scan results are available:
\verbatim
<2>CTRL-EVENT-SCAN-RESULTS
\endverbatim
Following priority levels are used:
- 0 = MSGDUMP
- 1 = DEBUG
- 2 = INFO
- 3 = WARNING
- 4 = ERROR
By default, any priority level greater than equal to 2 (INFO) are
delivered over the attached control interface. LEVEL command can be
used to set the level of messages which will be delivered. It should
be noted that there are many debug messages that do not include any
particulat prefix and are subject to change. They may be used for
debug information, but can usually be ignored by external programs.
In most cases, the external program can skip over the priority field
in the beginning of the event message and then compare the following
text to the event strings from wpa_ctrl.h that the program is
interested in processing.
Following subsections describe the most common event notifications
generated by %wpa_supplicant.
