+ * implementation shall not be assumed to be secure as the sole source of

+ * os_get_random() and as such, calls to os_get_random() can be replaced with
+ * calls to random_get_bytes() without reducing security.
+ *
+ * The design here follows partially the design used in the Linux

/**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ * these registrations are ignored until the interface type is
+ * changed again. This means that changing the interface type can
+ * lead to a situation that couldn't otherwise be produced, but
+ * any such registrations will be dormant in the sense that they
+ * will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+/**
+ * DOC: Virtual interface / concurrency capabilities
+ *
+ * Some devices are able to operate with virtual MACs, they can have
+ * more than one virtual interface. The capability handling for this
+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.
+ *
+ * All together, these attributes define the concurrency of virtual
+ * interfaces that a given device supports.

- * The registration cannot be dropped, but is removed automatically
- * when the netlink socket is closed. Multiple registrations can be made.
- * @NL80211_CMD_ACTION: Action frame TX request and RX notification. This
- * command is used both as a request to transmit an Action frame and as an
- * event indicating reception of an Action frame that was not processed in
+ * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
+ * (via @NL80211_CMD_FRAME) for processing in userspace. This command
+ * requires an interface index, a frame type attribute (optional for
+ * backward compatibility reasons, if not given assumes action frames)

+ * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
+ * backward compatibility
+ * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
+ * command is used both as a request to transmit a management frame and
+ * as an event indicating reception of a frame that was not processed in
* kernel code, but is for us (i.e., which may need to be processed in a
* user space application). %NL80211_ATTR_FRAME is used to specify the
* frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
* optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
- * which channel the frame is to be transmitted or was received. This
- * channel has to be the current channel (remain-on-channel or the
- * operational channel). When called, this operation returns a cookie
- * (%NL80211_ATTR_COOKIE) that will be included with the TX status event
- * pertaining to the TX request.
- * @NL80211_CMD_ACTION_TX_STATUS: Report TX status of an Action frame
- * transmitted with %NL80211_CMD_ACTION. %NL80211_ATTR_COOKIE identifies
+ * which channel the frame is to be transmitted or was received. If this
+ * channel is not the current channel (remain-on-channel or the
+ * operational channel) the device will switch to the given channel and
+ * transmit the frame, optionally waiting for a response for the time
+ * specified using %NL80211_ATTR_DURATION. When called, this operation
+ * returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
+ * TX status event pertaining to the TX request.
+ * %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ * management frames at CCK rate or not in 2GHz band.
+ * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
+ * command may be used with the corresponding cookie to cancel the wait
+ * time if it is known that it is no longer necessary.
+ * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
+ * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
+ * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
* the TX command and %NL80211_ATTR_FRAME includes the contents of the
* frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
* the frame.
+ * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
+ * backward compatibility.
* @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
* is used to configure connection quality monitoring notification trigger
* levels.
* @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
* command is used as an event to indicate the that a trigger level was
* reached.
+ * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
+ * and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
+ * by %NL80211_ATTR_IFINDEX) shall operate on.
+ * In case multiple channels are supported by the device, the mechanism
+ * with which it switches channels is implementation-defined.
+ * When a monitor interface is given, it can only switch channel while
+ * no other interfaces are operating to avoid disturbing the operation
+ * of any other interfaces, and other interfaces will again take
+ * precedence when they are used.
+ *
+ * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
+ *
+ * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
+ * mesh config parameters may be given.
+ * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
+ * network is determined by the network interface.
+ *
+ * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
+ * notification. This event is used to indicate that an unprotected
+ * deauthentication frame was dropped when MFP is in use.
+ * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
+ * notification. This event is used to indicate that an unprotected
+ * disassociation frame was dropped when MFP is in use.
+ *
+ * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
+ * beacon or probe response from a compatible mesh peer. This is only
+ * sent while no station information (sta_info) exists for the new peer
+ * candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set. On
+ * reception of this notification, userspace may decide to create a new
+ * station (@NL80211_CMD_NEW_STATION). To stop this notification from
+ * reoccurring, the userspace authentication daemon may want to create the
+ * new station with the AUTHENTICATED flag unset and maybe change it later
+ * depending on the authentication result.
+ *
+ * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
+ * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
+ * Since wireless is more complex than wired ethernet, it supports
+ * various triggers. These triggers can be configured through this
+ * command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
+ * more background information, see
+ * http://wireless.kernel.org/en/users/Documentation/WoWLAN.
+ *
+ * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
+ * the necessary information for supporting GTK rekey offload. This
+ * feature is typically used during WoWLAN. The configuration data
+ * is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
+ * contains the data in sub-attributes). After rekeying happened,
+ * this command may also be sent by the driver as an MLME event to
+ * inform userspace of the new replay counter.
+ *
+ * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
+ * of PMKSA caching dandidates.
+ *
+ * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
+ * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
*
* @NL80211_CMD_MAX: highest used command number

+ * For a match to succeed, the BSS must match all attributes of a
+ * set. Since not every hardware supports matching all types of
+ * attributes, there is no guarantee that the reported BSSs are
+ * fully complying with the match sets and userspace needs to be
+ * able to ignore them by itself.
+ * Thus, the implementation is somewhat hardware-dependent, but
+ * this is only an optimization and the userspace application
+ * needs to handle all the non-filtered results anyway.
+ * If the match attributes don't make sense when combined with
+ * the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID

ChangeLog for wpa_supplicant
-2010-09-07 - v0.7.3
- * fixed fallback from failed PMKSA caching into full EAP authentication
- [Bug 355]
- * fixed issue with early D-Bus signals during initialization
- * fixed X.509 name handling in internal TLS
- * fixed WPS ER to use corrent Enrollee MAC Address in Credential
- * fixed scanning routines ot improve AP selection for WPS
- * added WPS workaround for open networks
- * fixed WPS Diffie-Hellman derivation to use correct public key length
- * fixed wpa_supplicant AP mode operations to ignore Supplicant and
- scan result events
- * improved SME operations with nl80211
- * fixed WPS ER event_id handling in some cases
- * fixed some issues with bgscan simple to avoid unnecessary scans
- * fixed issue with l2_packet_ndis overlapped writes corrupting stack
- [Bug 328]
- * updated WinPcap to the latest stable version 4.1.2 in Windows
- installer
+2012-04-18 - v1.0
+ * bsd: Add support for setting HT values in IFM_MMASK.
+ * Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
+ This allows the driver to use PS buffering of Deauthentication and
+ Disassociation frames when the STA is in power save sleep. Only
+ available with drivers that provide TX status events for Deauth/
+ Disassoc frames (nl80211).
+ * Drop oldest unknown BSS table entries first. This makes it less
+ likely to hit connection issues in environments with huge number
+ of visible APs.
+ * Add systemd support.
+ * Add support for setting the syslog facility from the config file
+ at build time.
+ * atheros: Add support for IEEE 802.11w configuration.
+ * AP mode: Allow enable HT20 if driver supports it, by setting the
+ config parameter ieee80211n.
+ * Allow AP mode to disconnect STAs based on low ACK condition (when
+ the data connection is not working properly, e.g., due to the STA
+ going outside the range of the AP). Disabled by default, enable by
+ config option disassoc_low_ack.
+ * nl80211:
+ - Support GTK rekey offload.
+ - Support PMKSA candidate events. This adds support for RSN
+ pre-authentication with nl80211 interface and drivers that handle
+ roaming internally.
+ * dbus:
+ - Add a DBus signal for EAP SM requests, emitted on the Interface
+ object.
+ - Export max scan ssids supported by the driver as MaxScanSSID.
+ - Add signal Certification for information about server certification.
+ - Add BSSExpireAge and BSSExpireCount interface properties and
+ support set/get, which allows for setting BSS cache expiration age
+ and expiration scan count.
+ - Add ConfigFile to AddInterface properties.
+ - Add Interface.Country property and support to get/set the value.
+ - Add DBus property CurrentAuthMode.
+ - P2P DBus API added.
+ - Emit property changed events (for property BSSs) when adding/
+ removing BSSs.
+ - Treat '' in SSIDs of Interface.Scan as a request for broadcast
+ scan, instead of ignoring it.
+ - Add DBus getter/setter for FastReauth.
+ - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
+ * wpa_cli:
+ - Send AP-STA-DISCONNECTED event when an AP disconnects a station
+ due to inactivity.
+ - Make second argument to set command optional. This can be used to
+ indicate a zero length value.
+ - Add signal_poll command.
+ - Add bss_expire_age and bss_expire_count commands to set/get BSS
+ cache expiration age and expiration scan count.
+ - Add ability to set scan interval (the time in seconds wpa_s waits
+ before requesting a new scan after failing to find a suitable
+ network in scan results) using scan_interval command.
+ - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
+ - Add command get version, that returns wpa_supplicant version string.
+ - Add command sta_autoconnect for disabling automatic reconnection
+ on receiving disconnection event.
+ - Setting bssid parameter to an empty string "" or any can now be
+ used to clear the bssid_set flag in a network block, i.e., to remove
+ bssid filtering.
+ - Add tdls_testing command to add a special testing feature for
+ changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
+ enabled as well.
+ - For interworking, add wpa_cli commands interworking_select,
+ interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
+ - Many P2P commands were added. See README-P2P.
+ - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
+ - Allow set command to change global config parameters.
+ - Add log_level command, which can be used to display the current
+ debugging level and to change the log level during run time.
+ - Add note command, which can be used to insert notes to the debug
+ log.
+ - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
+ can now be used to build wpa_cli with internal implementation of
+ line editing and history support. This can be used as a replacement
+ for CONFIG_READLINE=y.
+ * AP mode: Add max_num_sta config option, which can be used to limit
+ the number of stations allowed to connect to the AP.
+ * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
+ config file.
+ * wext: Increase scan timeout from 5 to 10 seconds.
+ * Add blacklist command, allowing an external program to
+ manage the BSS blacklist and display its current contents.
+ * WPS:
+ - Add wpa_cli wps_pin get command for generating random PINs. This can
+ be used in a UI to generate a PIN without starting WPS (or P2P)
+ operation.
+ - Set RF bands based on driver capabilities, instead of hardcoding
+ them.
+ - Add mechanism for indicating non-standard WPS errors.
+ - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks
+ by default.
+ - Add wps_ap_pin cli command for wpa_supplicant AP mode.
+ - Add wps_check_pin cli command for processing PIN from user input.
+ UIs can use this command to process a PIN entered by a user and to
+ validate the checksum digit (if present).
+ - Cancel WPS operation on PBC session overlap detection.
+ - New wps_cancel command in wpa_cli will cancel a pending WPS
+ operation.
+ - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
+ - Trigger WPS config update on Manufacturer, Model Name, Model
+ Number, and Serial Number changes.
+ - Fragment size is now configurable for EAP-WSC peer. Use
+ wpa_cli set wps_fragment_size <val>.
+ - Disable AP PIN after 10 consecutive failures. Slow down attacks on
+ failures up to 10.
+ - Allow AP to start in Enrollee mode without AP PIN for probing, to
+ be compatible with Windows 7.
+ - Add Config Error into WPS-FAIL events to provide more info to the
+ user on how to resolve the issue.
+ - Label and Display config methods are not allowed to be enabled
+ at the same time, since it is unclear which PIN to use if both
+ methods are advertised.
+ - When controlling multiple interfaces:
+ - apply WPS commands to all interfaces configured to use WPS
+ - apply WPS config changes to all interfaces that use WPS
+ - when an attack is detected on any interface, disable AP PIN on
+ all interfaces
+ * WPS ER:
+ - Add special AP Setup Locked mode to allow read only ER.
+ ap_setup_locked=2 can now be used to enable a special mode where
+ WPS ER can learn the current AP settings, but cannot change them.
+ - Show SetSelectedRegistrar events as ctrl_iface events
+ - Add wps_er_set_config 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.
+ - Allow AP filtering based on IP address, add ctrl_iface event for
+ learned AP settings, add wps_er_config command to configure an AP.
+ * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
+ - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
+ for testing protocol extensibility.
+ - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
+ workarounds.
+ - Add support for AuthorizedMACs attribute.
+ * TDLS:
+ - Propogate TDLS related nl80211 capability flags from kernel and
+ add them as driver capability flags. If the driver doesn't support
+ capabilities, assume TDLS is supported internally. When TDLS is
+ explicitly not supported, disable all user facing TDLS operations.
+ - Allow TDLS to be disabled at runtime (mostly for testing).
+ Use set tdls_disabled.
+ - Honor AP TDLS settings that prohibit/allow TDLS.
+ - Add a special testing feature for changing TDLS behavior. Use
+ CONFIG_TDLS_TESTING build param to enable. Configure at runtime
+ with tdls_testing cli command.
+ - Add support for TDLS 802.11z.
+ * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
+ wlantest can be used to capture frames from a monitor interface
+ for realtime capturing or from pcap files for offline analysis.
+ * Interworking: Support added for 802.11u. Enable in .config with
+ CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
+ for interworking. wpa_cli commands added to support this are
+ interworking_select, interworking_connect, anqp_get, fetch_anqp,
+ and stop_fetch_anqp.
+ * Android: Add build and runtime support for Android wpa_supplicant.
+ * bgscan learn: Add new bgscan that learns BSS information based on
+ previous scans, and uses that information to dynamically generate
+ the list of channels for background scans.
+ * Add a new debug message level for excessive information. Use
+ -ddd to enable.
+ * TLS: Add support for tls_disable_time_checks=1 in client mode.
+ * Internal TLS:
+ - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
+ CONFIG_TLSV11.
+ - Add domainComponent parser for X.509 names.
+ * Linux: Add RFKill support by adding an interface state "disabled".
+ * Reorder some IEs to get closer to IEEE 802.11 standard. Move
+ WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
+ Move HT IEs to be later in (Re)Assoc Resp.
+ * Solaris: Add support for wired 802.1X client.
+ * Wi-Fi Direct support. See README-P2P for more information.
+ * Many bugfixes.
2010-04-18 - v0.7.2
* nl80211: fixed number of issues with roaming

+wpa_supplicant and Wi-Fi P2P
+============================
+
+This document describes how the Wi-Fi P2P implementation in
+wpa_supplicant can be configured and how an external component on the
+client (e.g., management GUI) is used to enable WPS enrollment and
+registrar registration.
+
+
+Introduction to Wi-Fi P2P
+-------------------------
+
+TODO
+
+More information about Wi-Fi P2P is available from Wi-Fi Alliance:
+http://www.wi-fi.org/Wi-Fi_Direct.php
+
+
+wpa_supplicant implementation
+-----------------------------
+
+TODO
+
+
+wpa_supplicant configuration
+----------------------------
+
+Wi-Fi P2P is an optional component that needs to be enabled in the
+wpa_supplicant build configuration (.config). Here is an example
+configuration that includes Wi-Fi P2P support and Linux nl80211
+-based driver interface:
+
+CONFIG_DRIVER_NL80211=y
+CONFIG_CTRL_IFACE=y
+CONFIG_P2P=y
+CONFIG_AP=y
+CONFIG_WPS=y
+
+
+In run-time configuration file (wpa_supplicant.conf), some parameters
+for P2P may be set. In order to make the devices easier to recognize,
+device_name and device_type should be specified. For example,
+something like this should be included:
+
+ctrl_interface=/var/run/wpa_supplicant
+device_name=My P2P Device
+device_type=1-0050F204-1
+
+
+wpa_cli
+-------
+
+Actual Wi-Fi P2P operations are requested during runtime. These can be
+done for example using wpa_cli (which is described below) or a GUI
+like wpa_gui-qt4.
+
+
+wpa_cli starts in interactive mode if no command string is included on
+the command line. By default, it will select the first network interface
+that it can find (and that wpa_supplicant controls). If more than one
+interface is in use, it may be necessary to select one of the explicitly
+by adding -i argument on the command line (e.g., 'wpa_cli -i wlan1').
+
+Most of the P2P operations are done on the main interface (e.g., the
+interface that is automatically added when the driver is loaded, e.g.,
+wlan0). When using a separate virtual interface for group operations
+(e.g., wlan1), the control interface for that group interface may need
+to be used for some operations (mainly WPS activation in GO). This may
+change in the future so that all the needed operations could be done
+over the main control interface.
+
+Device Discovery
+
+p2p_find [timeout in seconds] [type=<social|progressive>]
+
+The default behavior is to run a single full scan in the beginning and
+then scan only social channels. type=social will scan only social
+channels, i.e., it skips the initial full scan. type=progressive is
+like the default behavior, but it will scan through all the channels
+progressively one channel at the time in the Search state rounds. This
+will help in finding new groups or groups missed during the initial
+full scan.
+
+p2p_listen [timeout in seconds]
+
+Start Listen-only state (become discoverable without searching for
+other devices). 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.
+
+p2p_stop_find
+
+Stop ongoing P2P device discovery or other operation (connect, listen
+mode).
+
+p2p_flush
+
+Flush P2P peer table and state.
+
+Group Formation
+
+p2p_prov_disc <peer device address> <display|keypad|pbc> [join]
+
+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.
+
+The optional "join" parameter can be used to indicate that this command
+is requesting an already running GO to prepare for a new client. This is
+mainly used with "display" to request it to display a PIN.
+
+p2p_connect <peer device address> <pbc|pin|PIN#> [display|keypad]
+ [persistent] [join|auth] [go_intent=<0..15>] [freq=<in MHz>]
+
+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). [display|keypad] is used with PIN method
+to specify which PIN is used (display=dynamically generated random PIN
+from local display, keypad=PIN entered from peer 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. This will send a Provision
+Discovery Request message to the target GO before associating for WPS
+provisioning.
+
+"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.
+
+"go_intent" can be used to override the default GO Intent for this GO
+Negotiation.
+
+"freq" can be used to set a forced operating channel (e.g., freq=2412
+to select 2.4 GHz channel 1).
+
+p2p_group_add [persistent|persistent=<network id>] [freq=<freq in MHz>]
+
+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. Optional freq=<freq in MHz> can be used to force
+the GO to be started on a specific frequency. Special freq=2 or freq=5
+options can be used to request the best 2.4 GHz or 5 GHz band channel
+to be selected automatically.
+
+p2p_reject <peer device address>
+
+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.
+
+p2p_group_remove <group interface>
+
+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.
+
+p2p_cancel
+
+Cancel an ongoing P2P group formation related operation.
+
+Service Discovery
+
+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 available services of all service
+discovery protocols and requests this to be sent to all discovered
+peers (note: this can result in long response frames). The pending
+requests are sent during device discovery (see p2p_find).
+
+Only a single pending wildcard query is supported, but there can be
+multiple pending peer device specific queries (each will be sent in
+sequence whenever the peer is found).
+
+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.
+
+For UPnP, an alternative command format can be used to specify a
+single query TLV (i.e., a service discovery for a specific UPnP
+service):
+
+p2p_serv_disc_req 00:00:00:00:00:00 upnp <version hex> <ST: from M-SEARCH>
+
+For example:
+
+p2p_serv_disc_req 00:00:00:00:00:00 upnp 10 urn:schemas-upnp-org:device:InternetGatewayDevice:1

+p2p_serv_disc_req 00:00:00:00:00:00 upnp 10 urn:schemas-upnp-org:device:InternetGatewayDevice:1
+
+p2p_serv_disc_cancel_req <query identifier>
+
+Cancel a pending P2P service discovery request. This command takes a
+single parameter: identifier for the pending query (the value returned
+by p2p_serv_disc_req, e.g., "p2p_serv_disc_cancel_req 1f77628".
+
+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". This command is used only if external program is used
+to process the request (see p2p_serv_disc_external).
+
+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. This is only needed when external
+service discovery processing is enabled since the commands to
+pre-configure services for internal processing will increment the
+indicator automatically.
+
+p2p_serv_disc_external <0|1>
+
+Configure external processing of P2P service requests: 0 (default) =
+no external processing of requests (i.e., internal code will process
+each request based on pre-configured services), 1 = external
+processing of requests (external program is responsible for replying
+to service discovery requests with p2p_serv_disc_resp). Please note
+that there is quite strict limit on how quickly the response needs to
+be transmitted, so use of the internal processing is strongly
+recommended.
+
+p2p_service_add bonjour <query hexdump> <RDATA hexdump>
+
+Add a local Bonjour service for internal SD query processing.

+
+Invitation
+
+p2p_invite [persistent=<network id>|group=<group ifname>] [peer=address]
+ [go_dev_addr=address]
+
+Invite a peer to join a group (e.g., group=wlan1) or to reinvoke a
+persistent group (e.g., persistent=4). If the peer device is the GO of
+the persisten group, the peer parameter is not needed. Otherwise it is
+used to specify which device to invite. go_dev_addr parameter can be
+used to override the GO device address for Invitation Request should
+it be not known for some reason (this should not be needed in most
+cases).
+
+Group Operations
+
+(These are used on the group interface.)
+
+wps_pin <any|address> <PIN>
+
+Start WPS PIN method. This allows a single WPS Enrollee to connect to
+the AP/GO. This is used on the GO when a P2P client joins an existing
+group. The second parameter is the address of the Enrollee or a string
+"any" to allow any station to use the entered PIN (which will restrict
+the PIN for one-time-use). PIN is the Enrollee PIN read either from a
+label or display on the P2P Client/WPS Enrollee.
+
+wps_pbc
+
+Start WPS PBC method (i.e., push the button). This allows a single WPS
+Enrollee to connect to the AP/GO. This is used on the GO when a P2P
+client joins an existing group.
+
+p2p_get_passphrase
+
+Get the passphrase for a group (only available when acting as a GO).
+
+p2p_presence_req [<duration> <interval>] [<duration> <interval>]
+
+Send a P2P Presence Request to the GO (this is only available when
+acting as a P2P client). If no duration/interval pairs are given, the
+request indicates that this client has no special needs for GO
+presence. the first parameter pair gives the preferred duration and
+interval values in microseconds. If the second pair is included, that
+indicates which value would be acceptable.
+
+Parameters
+
+p2p_ext_listen [<period> <interval>]
+
+Configure Extended Listen Timing. If the parameters are omitted, this
+feature is disabled. If the parameters are included, Listen State will
+be entered every interval msec for at least period msec. Both values
+have acceptable range of 1-65535 (with interval obviously having to be
+larger than or equal to duration). If the P2P module is not idle at
+the time the Extended Listen Timing timeout occurs, the Listen State
+operation will be skipped.
+
+The configured values will also be advertised to other P2P Devices. The
+received values are available in the p2p_peer command output:
+
+ext_listen_period=100 ext_listen_interval=5000
+
+p2p_set <field> <value>
+
+Change dynamic P2P parameters
+
+p2p_set discoverability <0/1>
+
+Disable/enable advertisement of client discoverability. This is
+enabled by default and this parameter is mainly used to allow testing
+of device discoverability.
+
+p2p_set managed <0/1>
+
+Disable/enable managed P2P Device operations. This is disabled by
+default.
+
+p2p_set listen_channel <1/6/11>
+
+Set P2P Listen channel. This is mainly meant for testing purposes and
+changing the Listen channel during normal operations can result in
+protocol failures.
+
+p2p_set ssid_postfix <postfix>
+
+Set postfix string to be added to the automatically generated P2P SSID
+(DIRECT-<two random characters>). For example, postfix of "-testing"
+could result in the SSID becoming DIRECT-ab-testing.
+
+set <field> <value>
+
+Set global configuration parameters which may also affect P2P
+operations. The format on these parameters is same as is used in
+wpa_supplicant.conf. Only the parameters listen here should be
+changed. Modifying other parameters may result in incorrect behavior
+since not all existing users of the parameters are updated.
+
+set uuid <UUID>
+
+Set WPS UUID (by default, this is generated based on the MAC address).
+
+set device_name <device name>
+
+Set WPS Device Name (also included in some P2P messages).
+
+set manufacturer <manufacturer>
+
+Set WPS Manufacturer.
+
+set model_name <model name>
+
+Set WPS Model Name.
+
+set model_number <model number>
+
+Set WPS Model Number.
+
+set serial_number <serial number>
+
+Set WPS Serial Number.

+set config_methods <config methods>
+
+Set WPS Configuration Methods.
+
+set sec_device_type <device type>
+
+Add a new Secondary Device Type.
+
+set p2p_go_intent <GO intent>
+
+Set the default P2P GO Intent. Note: This value can be overridden in
+p2p_connect command and as such, there should be no need to change the
+default value here during normal operations.
+
+set p2p_ssid_postfix <P2P SSID postfix>
+
+Set P2P SSID postfix.
+
+set persistent_reconnect <0/1>
+
+Disable/enabled persistent reconnect for reinvocation of persistent
+groups. If enabled, invitations to reinvoke a persistent group will be
+accepted without separate authorization (e.g., user interaction).
+
+set country <two character country code>
+
+Set country code (this is included in some P2P messages).
+
+Status
+
+p2p_peers [discovered]
+
+List P2P Device Addresses of all the P2P peers we know. The optional
+"discovered" parameter filters out the peers that we have not fully
+discovered, i.e., which we have only seen in a received Probe Request
+frame.

wpa_supplicant includes an optional WPS component that can be used as
an Enrollee to enroll new network credential or as a Registrar to
-configure an AP. The current version of wpa_supplicant does not
-support operation as an external WLAN Management Registrar for adding
-new client devices or configuring the AP over UPnP.
+configure an AP.
wpa_supplicant configuration
WPS is an optional component that needs to be enabled in
wpa_supplicant build configuration (.config). Here is an example
-configuration that includes WPS support and Linux wireless extensions
--based driver interface:
+configuration that includes WPS support and Linux nl80211 -based
+driver interface:
-CONFIG_DRIVER_WEXT=y
+CONFIG_DRIVER_NL80211=y
CONFIG_WPS=y
+CONFIG_WPS2=y
+
+If you want to enable WPS external registrar (ER) functionality, you
+will also need to add following line:
+
+CONFIG_WPS_ER=y
WPS needs the Universally Unique IDentifier (UUID; see RFC 4122) for
network. wpa_supplicant uses the control interface as an input channel
for these events.
+The PIN value used in the commands must be processed by an UI to
+remove non-digit characters and potentially, to verify the checksum
+digit. "wpa_cli wps_check_pin <PIN>" can be used to do such processing.
+It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if the checksum
+digit is incorrect, or the processed PIN (non-digit characters removed)
+if the PIN is valid.
+
If the client device has a display, a random PIN has to be generated
for each WPS registration session. wpa_supplicant can do this with a
control interface request, e.g., by calling wpa_cli:
generated PIN.
+If a random PIN is needed for a user interface, "wpa_cli wps_pin get"
+can be used to generate a new PIN without starting WPS negotiation.
+This random PIN can then be passed as an argument to another wps_pin
+call when the actual operation should be started.
+
If the client design wants to support optional WPS PBC mode, this can
be enabled by either a physical button in the client device or a
virtual button in the user interface. The PBC operation requires that
WPS-CRED-RECEIVED <hexdump of Credential attribute(s)>
For example:
<2>WPS-CRED-RECEIVED 100e006f10260001011045000c6a6b6d2d7770732d74657374100300020020100f000200081027004030653462303435366332363666653064333961643135353461316634626637313234333761636664623766333939653534663166316230323061643434386235102000060266a0ee1727
+
+
+wpa_supplicant as WPS External Registrar (ER)
+---------------------------------------------
+
+wpa_supplicant can be used as a WPS ER to configure an AP or enroll
+new Enrollee to join the network. This functionality uses UPnP and
+requires that a working IP connectivity is available with the AP (this
+can be either over a wired or wireless connection).
+
+Separate wpa_supplicant process can be started for WPS ER
+operations. A special "none" driver can be used in such a case to
+indicate that no local network interface is actually controlled. For
+example, following command could be used to start the ER:
+
+wpa_supplicant -Dnone -c er.conf -ieth0
+
+Sample er.conf:
+
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=admin
+device_name=WPS External Registrar
+
+
+wpa_cli commands for ER functionality:
+
+wps_er_start [IP address]
+- start WPS ER functionality
+- the optional IP address parameter can be used to filter operations only

+# wpa_supplicant depends on strong random number generation being available
+# from the operating system. os_get_random() function is used to fetch random
+# data when needed, e.g., for key generation. On Linux and BSD systems, this
+# works by reading /dev/urandom. It should be noted that the OS entropy pool
+# needs to be properly initialized before wpa_supplicant is started. This is
+# important especially on embedded devices that do not have a hardware random
+# number generator and may by default start up with minimal entropy available
+# for random number generation.
+#
+# As a safety net, wpa_supplicant is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data fetched
+# from the OS. This by itself is not considered to be very strong, but it may
+# help in cases where the system pool is not initialized properly. However, it
+# is very strongly recommended that the system pool is initialized with enough
+# entropy either by using hardware assisted random number generator or by
+# storing state over device reboots.
+#
+# wpa_supplicant can be configured to maintain its own entropy store over
+# restarts to enhance random number generation. This is not perfect, but it is
+# much more secure than using the same sequence of random numbers after every
+# reboot. This can be enabled with -e<entropy file> command line option. The
+# specified file needs to be readable and writable by wpa_supplicant.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random
+# data from /dev/urandom), the internal wpa_supplicant random pool can be
+# disabled. This will save some in binary size and CPU use. However, this
+# should only be considered for builds that are known to be used on devices
+# that meet the requirements described above.
