This is similar to MLME-AUTHENTICATE.confirm primitive in the + * MLME SAP interface (kernel providing MLME, userspace SME). The + * included %NL80211_ATTR_FRAME attribute contains the management frame + * (including both the header and frame body, but not FCS). This event is + * also used to indicate if the authentication attempt timed out. In that + * case the %NL80211_ATTR_FRAME attribute is replaced with a + * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which + * pending authentication timed out). + * @NL80211_CMD_ASSOCIATE: association request and notification; like + * NL80211_CMD_AUTHENTICATE but for Association and Reassociation + * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request, + * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). + * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like + * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to + * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication + * primitives). + * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like + * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to + * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives). + * + * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael + * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the + * event includes %NL80211_ATTR_MAC to describe the source MAC address of + * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key + * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and + * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this + * event matches with MLME-MICHAELMICFAILURE.indication() primitive + * + * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a + * FREQ attribute (for the initial frequency if no peer can be found) + * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those + * should be fixed rather than automatically determined. Can only be + * executed on a network interface that is UP, and fixed BSSID/FREQ + * may be rejected. Another optional parameter is the beacon interval, + * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not + * given defaults to 100 TU (102.4ms). + * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is + * determined by the network interface. + * + * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute + * to identify the device, and the TESTDATA blob attribute to pass through + * to the driver. + * + * @NL80211_CMD_CONNECT: connection request and notification; this command + * requests to connect to a specified network but without separating + * auth and assoc steps. For this, you need to specify the SSID in a + * %NL80211_ATTR_SSID attribute, and can optionally specify the association + * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP, + * %NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT, + * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE, + * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and + * %NL80211_ATTR_WIPHY_FREQ_HINT. + * If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are + * restrictions on BSS selection, i.e., they effectively prevent roaming + * within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT + * can be included to provide a recommendation of the initial BSS while + * allowing the driver to roam to other BSSes within the ESS and also to + * ignore this recommendation if the indicated BSS is not ideal. Only one + * set of BSSID,frequency parameters is used (i.e., either the enforcing + * %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict + * %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT). + * Background scan period can optionally be + * specified in %NL80211_ATTR_BG_SCAN_PERIOD, + * if not specified default background scan configuration + * in driver is used and if period value is 0, bg scan will be disabled. + * This attribute is ignored if driver does not support roam scan. + * It is also sent as an event, with the BSSID and response IEs when the + * connection is established or failed to be established. This can be + * determined by the STATUS_CODE attribute. + * @NL80211_CMD_ROAM: request that the card roam (currently not implemented), + * sent as an event when the card/driver roamed by itself. + * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify + * userspace that a connection was dropped by the AP or due to other + * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and + * %NL80211_ATTR_REASON_CODE attributes are used. + * + * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices + * associated with this wiphy must be down and will follow. + * + * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified + * channel for the specified amount of time. This can be used to do + * off-channel operations like transmit a Public Action frame and wait for + * a response while being associated to an AP on another channel. + * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus + * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the + * frequency for the operation. + * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds + * to remain on the channel. This command is also used as an event to + * notify when the requested duration starts (it may take a while for the + * driver to schedule this time due to other concurrent needs for the + * radio). + * When called, this operation returns a cookie (%NL80211_ATTR_COOKIE) + * that will be included with any events pertaining to this request; + * the cookie is also used to cancel the request. + * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a + * pending remain-on-channel duration if the desired operation has been + * completed prior to expiration of the originally requested duration. + * %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the + * radio. The %NL80211_ATTR_COOKIE attribute must be given as well to + * uniquely identify the request. + * This command is also used as an event to notify when a requested + * remain-on-channel duration has expired. + * + * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX + * rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface + * and @NL80211_ATTR_TX_RATES the set of allowed rates. + * + * @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) + * and a match attribute containing the first few bytes of the frame + * that should match, e.g. a single byte for only a category match or + * four bytes for vendor frames including the OUI. The registration + * cannot be dropped, but is removed automatically when the netlink + * socket is closed. Multiple registrations can be made. + * @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 is used + * to indicate on 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_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA + * counters which will be updated to the current value. This attribute + * is used during CSA period. + * @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_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE + * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE + * + * @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 the attributes determining channel width) 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, + * @NL80211_MESH_SETUP_USERSPACE_AMPE, or + * @NL80211_MESH_SETUP_USERSPACE_MPM 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. + * The @NL80211_CMD_SET_WOWLAN command can also be used as a notification + * from the driver reporting the wakeup reason. In this case, the + * @NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason + * for the wakeup, if it was caused by wireless. If it is not present + * in the wakeup notification, the wireless device didn't cause the + * wakeup but reports that it was woken up. + * + * @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). + * In addition, this can be used as an event to request userspace to take + * actions on TDLS links (set up a new link or tear down an existing one). + * In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested + * operation, %NL80211_ATTR_MAC contains the peer MAC address, and + * %NL80211_ATTR_REASON_CODE the reason code to be used (only with + * %NL80211_TDLS_TEARDOWN). + * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The + * %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be + * sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as + * 802.11 management frames, while TDLS action codes (802.11-2012 + * 8.5.13.1) will be encapsulated and sent as data frames. The currently + * supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES + * and the currently supported TDLS actions codes are given in + * &enum ieee80211_tdls_actioncode. + * + * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP + * (or GO) interface (i.e. hostapd) to ask for unexpected frames to + * implement sending deauth to stations that send unexpected class 3 + * frames. Also used as the event sent by the kernel when such a frame + * is received. + * For the event, the %NL80211_ATTR_MAC attribute carries the TA and + * other attributes like the interface index are present. + * If used as the command it must have an interface index and you can + * only unsubscribe from the event by closing the socket. Subscription + * is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events. + * + * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the + * associated station identified by %NL80211_ATTR_MAC sent a 4addr frame + * and wasn't already in a 4-addr VLAN. The event will be sent similarly + * to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener. + * + * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface + * by sending a null data frame to it and reporting when the frame is + * acknowleged. This is used to allow timing out inactive clients. Uses + * %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a + * direct reply with an %NL80211_ATTR_COOKIE that is later used to match + * up the event with the request. The event includes the same data and + * has %NL80211_ATTR_ACK set if the frame was ACKed. + * + * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from + * other BSSes when any interfaces are in AP mode. This helps implement + * OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME + * messages. Note that per PHY only one application may register. + * + * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether + * No Acknowledgement Policy should be applied. + * + * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels + * independently of the userspace SME, send this event indicating + * %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the + * attributes determining channel width. This indication may also be + * sent when a remotely-initiated switch (e.g., when a STA receives a CSA + * from the remote AP) is completed; + * + * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch + * has been started on an interface, regardless of the initiator + * (ie. whether it was requested from a remote device or + * initiated on our own). It indicates that + * %NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ + * after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's. The userspace may + * decide to react to this indication by requesting other + * interfaces to change channel as well. + * + * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by + * its %NL80211_ATTR_WDEV identifier. It must have been created with + * %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the + * P2P Device can be used for P2P operations, e.g. remain-on-channel and + * public action frame TX. + * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by + * its %NL80211_ATTR_WDEV identifier. + * + * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to + * notify userspace that AP has rejected the connection request from a + * station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON + * is used for this. + * + * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames + * for IBSS or MESH vif. + * + * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control. + * This is to be used with the drivers advertising the support of MAC + * address based access control. List of MAC addresses is passed in + * %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in + * %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it + * is not already done. The new list will replace any existing list. Driver + * will clear its ACL when the list of MAC addresses passed is empty. This + * command is used in AP/P2P GO mode. Driver has to make sure to clear its + * ACL list during %NL80211_CMD_STOP_AP. + * + * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once + * a radar is detected or the channel availability scan (CAC) has finished + * or was aborted, or a radar was detected, usermode will be notified with + * this event. This command is also used to notify userspace about radars + * while operating on this channel. + * %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the + * event. + * + * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features, + * i.e. features for the nl80211 protocol rather than device features. + * Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap. + * + * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition + * Information Element to the WLAN driver + * + * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver + * to the supplicant. This will carry the target AP's MAC address along + * with the relevant Information Elements. This event is used to report + * received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE). + * + * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running + * a critical protocol that needs more reliability in the connection to + * complete. + * + * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can + * return back to normal. + * + * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules. + * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules. + * + * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the + * the new channel information (Channel Switch Announcement - CSA) + * in the beacon for some time (as defined in the + * %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the + * new channel. Userspace provides the new channel information (using + * %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel + * width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform + * other station that transmission must be blocked until the channel + * switch is complete. + * + * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified + * by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in + * %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in + * %NL80211_ATTR_VENDOR_DATA. + * For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is + * used in the wiphy data as a nested attribute containing descriptions + * (&struct nl80211_vendor_cmd_info) of the supported vendor commands. + * This may also be sent as an event with the same attributes. + * + * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values. + * The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If + * that attribute is not included, QoS mapping is disabled. Since this + * QoS mapping is relevant for IP packets, it is only valid during an + * association. This is cleared on disassociation and AP restart. + * + * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given + * %NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO + * and %NL80211_ATTR_ADMITTED_TIME parameters. + * Note that the action frame handshake with the AP shall be handled by + * userspace via the normal management RX/TX framework, this only sets + * up the TX TS in the driver/device. + * If the admitted time attribute is not added then the request just checks + * if a subsequent setup could be successful, the intent is to use this to + * avoid setting up a session with the AP when local restrictions would + * make that impossible. However, the subsequent "real" setup may still + * fail even if the check was successful. + * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID + * and %NL80211_ATTR_MAC parameters. It isn't necessary to call this + * before removing a station entry entirely, or before disassociating + * or similar, cleanup will happen in the driver/device in this case. + * + * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to + * destination %NL80211_ATTR_MAC on the interface identified by + * %NL80211_ATTR_IFINDEX. + * + * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and + * bandwidth of a channel must be given. + * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the + * network is determined by the network interface. + * + * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer, + * identified by the %NL80211_ATTR_MAC parameter. A target channel is + * provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining + * channel width/type. The target operating class is given via + * %NL80211_ATTR_OPER_CLASS. + * The driver is responsible for continually initiating channel-switching + * operations and returning to the base channel for communication with the + * AP. + * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS + * peer given by %NL80211_ATTR_MAC.
