| * DOC: Introduction |
| * |
| * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges |
| * userspace and drivers, and offers some utility functionality associated |
| * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used |
| * by all modern wireless drivers in Linux, so that they offer a consistent |
| * API through nl80211. For backward compatibility, cfg80211 also offers |
| * wireless extensions to userspace, but hides them from drivers completely. |
| * |
| * Additionally, cfg80211 contains code to help enforce regulatory spectrum |
| * use restrictions. |

| |
| |
| /** |
| * DOC: Device registration |
| * |
| * In order for a driver to use cfg80211, it must register the hardware device |
| * with cfg80211. This happens through a number of hardware capability structs |
| * described below. |
| * |
| * The fundamental structure for each device is the 'wiphy', of which each |
| * instance describes a physical wireless device connected to the system. Each |
| * such wiphy can have zero, one, or many virtual interfaces associated with |
| * it, which need to be identified as such by pointing the network interface's |
| * @ieee80211_ptr pointer to a &struct wireless_dev which further describes |
| * the wireless part of the interface, normally this struct is embedded in the |
| * network interface's private data area. Drivers can optionally allow creating |
| * or destroying virtual interfaces on the fly, but without at least one or the |
| * ability to create some the wireless device isn't useful. |
| * |
| * Each wiphy structure contains device capability information, and also has |
| * a pointer to the various operations the driver offers. The definitions and |
| * structures here describe these capabilities in detail. |

| * channels to scan, and the SSIDs to send probe requests for (including the |

| /** |
| * struct cfg80211_ops - backend description for wireless configuration |
| * |
| * This struct is registered by fullmac card drivers and/or wireless stacks |
| * in order to handle configuration requests on their interfaces. |
| * |
| * All callbacks except where otherwise noted should return 0 |
| * on success or a negative error code. |
| * |
| * All operations are currently invoked under rtnl for consistency with the |
| * wireless extensions but this is subject to reevaluation as soon as this |
| * code is used more widely and we have a first user without wext. |
| * |
| * @suspend: wiphy device needs to be suspended. The variable @wow will |
| * be %NULL or contain the enabled Wake-on-Wireless triggers that are |
| * configured for the device. |
| * @resume: wiphy device needs to be resumed |
| * @set_wakeup: Called when WoWLAN is enabled/disabled, use this callback |
| * to call device_set_wakeup_enable() to enable/disable wakeup from |
| * the device. |
| * |
| * @add_virtual_intf: create a new virtual interface with the given name, |
| * must set the struct wireless_dev's iftype. Beware: You must create |
| * the new netdev in the wiphy's network namespace! Returns the struct |
| * wireless_dev, or an ERR_PTR. For P2P device wdevs, the driver must |
| * also set the address member in the wdev. |
| * |
| * @del_virtual_intf: remove the virtual interface |
| * |
| * @change_virtual_intf: change type/configuration of virtual interface, |
| * keep the struct wireless_dev's iftype updated. |
| * |
| * @add_key: add a key with the given parameters. @mac_addr will be %NULL |
| * when adding a group key. |
| * |
| * @get_key: get information about the key with the given parameters. |
| * @mac_addr will be %NULL when requesting information for a group |
| * key. All pointers given to the @callback function need not be valid |
| * after it returns. This function should return an error if it is |
| * not possible to retrieve the key, -ENOENT if it doesn't exist. |
| * |
| * @del_key: remove a key given the @mac_addr (%NULL for a group key) |
| * and @key_index, return -ENOENT if the key doesn't exist. |
| * |
| * @set_default_key: set the default key on an interface |
| * |
| * @set_default_mgmt_key: set the default management frame key on an interface |
| * |
| * @set_rekey_data: give the data necessary for GTK rekeying to the driver |
| * |
| * @start_ap: Start acting in AP mode defined by the parameters. |
| * @change_beacon: Change the beacon parameters for an access point mode |
| * interface. This should reject the call when AP mode wasn't started. |
| * @stop_ap: Stop being an AP, including stopping beaconing. |
| * |
| * @add_station: Add a new station. |
| * @del_station: Remove a station |
| * @change_station: Modify a given station. Note that flags changes are not much |
| * validated in cfg80211, in particular the auth/assoc/authorized flags |
| * might come to the driver in invalid combinations -- make sure to check |
| * them, also against the existing state! Drivers must call |
| * cfg80211_check_station_change() to validate the information. |
| * @get_station: get station information for the station identified by @mac |
| * @dump_station: dump station callback -- resume dump at index @idx |
| * |
| * @add_mpath: add a fixed mesh path |
| * @del_mpath: delete a given mesh path |
| * @change_mpath: change a given mesh path |
| * @get_mpath: get a mesh path for the given parameters |
| * @dump_mpath: dump mesh path callback -- resume dump at index @idx |
| * @get_mpp: get a mesh proxy path for the given parameters |
| * @dump_mpp: dump mesh proxy path callback -- resume dump at index @idx |
| * @join_mesh: join the mesh network with the specified parameters |
| * (invoked with the wireless_dev mutex held) |
| * @leave_mesh: leave the current mesh network |
| * (invoked with the wireless_dev mutex held) |
| * |
| * @get_mesh_config: Get the current mesh configuration |
| * |
| * @update_mesh_config: Update mesh parameters on a running mesh. |
| * The mask is a bitfield which tells us which parameters to |
| * set, and which to leave alone. |
| * |
| * @change_bss: Modify parameters for a given BSS. |
| * |
| * @set_txq_params: Set TX queue parameters |
| * |
| * @libertas_set_mesh_channel: Only for backward compatibility for libertas, |
| * as it doesn't implement join_mesh and needs to set the channel to |
| * join the mesh instead. |
| * |
| * @set_monitor_channel: Set the monitor mode channel for the device. If other |
| * interfaces are active this callback should reject the configuration. |
| * If no interfaces are active or the device is down, the channel should |
| * be stored for when a monitor interface becomes active. |
| * |
| * @scan: Request to do a scan. If returning zero, the scan request is given |
| * the driver, and will be valid until passed to cfg80211_scan_done(). |
| * For scan results, call cfg80211_inform_bss(); you can call this outside |
| * the scan/scan_done bracket too. |
| * @abort_scan: Tell the driver to abort an ongoing scan. The driver shall |
| * indicate the status of the scan through cfg80211_scan_done(). |
| * |
| * @auth: Request to authenticate with the specified peer |
| * (invoked with the wireless_dev mutex held) |
| * @assoc: Request to (re)associate with the specified peer |
| * (invoked with the wireless_dev mutex held) |
| * @deauth: Request to deauthenticate from the specified peer |
| * (invoked with the wireless_dev mutex held) |
| * @disassoc: Request to disassociate from the specified peer |
| * (invoked with the wireless_dev mutex held) |
| * |
| * @connect: Connect to the ESS with the specified parameters. When connected, |
| * call cfg80211_connect_result()/cfg80211_connect_bss() with status code |
| * %WLAN_STATUS_SUCCESS. If the connection fails for some reason, call |
| * cfg80211_connect_result()/cfg80211_connect_bss() with the status code |
| * from the AP or cfg80211_connect_timeout() if no frame with status code |
| * was received. |
| * The driver is allowed to roam to other BSSes within the ESS when the |
| * other BSS matches the connect parameters. When such roaming is initiated |
| * by the driver, the driver is expected to verify that the target matches |
| * the configured security parameters and to use Reassociation Request |
| * frame instead of Association Request frame. |
| * The connect function can also be used to request the driver to perform a |
| * specific roam when connected to an ESS. In that case, the prev_bssid |
| * parameter is set to the BSSID of the currently associated BSS as an |
| * indication of requesting reassociation. |
| * In both the driver-initiated and new connect() call initiated roaming |
| * cases, the result of roaming is indicated with a call to |
| * cfg80211_roamed() or cfg80211_roamed_bss(). |
| * (invoked with the wireless_dev mutex held) |
| * @disconnect: Disconnect from the BSS/ESS. Once done, call |
| * cfg80211_disconnected(). |
| * (invoked with the wireless_dev mutex held) |
| * |
| * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call |
| * cfg80211_ibss_joined(), also call that function when changing BSSID due |
| * to a merge. |
| * (invoked with the wireless_dev mutex held) |
| * @leave_ibss: Leave the IBSS. |
| * (invoked with the wireless_dev mutex held) |
| * |
| * @set_mcast_rate: Set the specified multicast rate (only if vif is in ADHOC or |
| * MESH mode) |
| * |
| * @set_wiphy_params: Notify that wiphy parameters have changed; |
| * @changed bitfield (see &enum wiphy_params_flags) describes which values |
| * have changed. The actual parameter values are available in |
| * struct wiphy. If returning an error, no value should be changed. |
| * |
| * @set_tx_power: set the transmit power according to the parameters, |
| * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The |
| * wdev may be %NULL if power was set for the wiphy, and will |
| * always be %NULL unless the driver supports per-vif TX power |
| * (as advertised by the nl80211 feature flag.) |
| * @get_tx_power: store the current TX power into the dbm variable; |
| * return 0 if successful |
| * |
| * @set_wds_peer: set the WDS peer for a WDS interface |
| * |
| * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting |
| * functions to adjust rfkill hw state |
| * |
| * @dump_survey: get site survey information. |
| * |
| * @remain_on_channel: Request the driver to remain awake on the specified |
| * channel for the specified duration to complete an off-channel |
| * operation (e.g., public action frame exchange). When the driver is |
| * ready on the requested channel, it must indicate this with an event |
| * notification by calling cfg80211_ready_on_channel(). |
| * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. |
| * This allows the operation to be terminated prior to timeout based on |
| * the duration value. |
| * @mgmt_tx: Transmit a management frame. |
| * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management |
| * frame on another channel |
| * |
| * @testmode_cmd: run a test mode command; @wdev may be %NULL |
| * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be |
| * used by the function, but 0 and 1 must not be touched. Additionally, |
| * return error codes other than -ENOBUFS and -ENOENT will terminate the |
| * dump and return to userspace with an error, so be careful. If any data |
| * was passed in from userspace then the data/len arguments will be present |
| * and point to the data contained in %NL80211_ATTR_TESTDATA. |
| * |
| * @set_bitrate_mask: set the bitrate mask configuration |
| * |
| * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac |
| * devices running firmwares capable of generating the (re) association |
| * RSN IE. It allows for faster roaming between WPA2 BSSIDs. |
| * @del_pmksa: Delete a cached PMKID. |
| * @flush_pmksa: Flush all cached PMKIDs. |
| * @set_power_mgmt: Configure WLAN power management. A timeout value of -1 |
| * allows the driver to adjust the dynamic ps timeout value. |
| * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold. |
| * After configuration, the driver should (soon) send an event indicating |
| * the current level is above/below the configured threshold; this may |
| * need some care when the configuration is changed (without first being |
| * disabled.) |
| * @set_cqm_txe_config: Configure connection quality monitor TX error |
| * thresholds. |
| * @sched_scan_start: Tell the driver to start a scheduled scan. |
| * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This |
| * call must stop the scheduled scan and be ready for starting a new one |
| * before it returns, i.e. @sched_scan_start may be called immediately |
| * after that again and should not fail in that case. The driver should |
| * not call cfg80211_sched_scan_stopped() for a requested stop (when this |
| * method returns 0.) |
| * |
| * @mgmt_frame_register: Notify driver that a management frame type was |
| * registered. The callback is allowed to sleep. |
| * |
| * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. |
| * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may |
| * reject TX/RX mask combinations they cannot support by returning -EINVAL |
| * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). |
| * |
| * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). |
| * |
| * @tdls_mgmt: Transmit a TDLS management frame. |
| * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup). |
| * |
| * @probe_client: probe an associated client, must return a cookie that it |
| * later passes to cfg80211_probe_status(). |
| * |
| * @set_noack_map: Set the NoAck Map for the TIDs. |
| * |
| * @get_channel: Get the current operating channel for the virtual interface. |
| * For monitor interfaces, it should return %NULL unless there's a single |
| * current monitoring channel. |
| * |
| * @start_p2p_device: Start the given P2P device. |
| * @stop_p2p_device: Stop the given P2P device. |
| * |
| * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode. |
| * Parameters include ACL policy, an array of MAC address of stations |
| * and the number of MAC addresses. If there is already a list in driver |
| * this new list replaces the existing one. Driver has to clear its ACL |
| * when number of MAC addresses entries is passed as 0. Drivers which |
| * advertise the support for MAC based ACL have to implement this callback. |
| * |
| * @start_radar_detection: Start radar detection in the driver. |
| * |
| * @update_ft_ies: Provide updated Fast BSS Transition information to the |
| * driver. If the SME is in the driver/firmware, this information can be |
| * used in building Authentication and Reassociation Request frames. |
| * |
| * @crit_proto_start: Indicates a critical protocol needs more link reliability |
| * for a given duration (milliseconds). The protocol is provided so the |
| * driver can take the most appropriate actions. |
| * @crit_proto_stop: Indicates critical protocol no longer needs increased link |
| * reliability. This operation can not fail. |
| * @set_coalesce: Set coalesce parameters. |
| * |
| * @channel_switch: initiate channel-switch procedure (with CSA). Driver is |
| * responsible for veryfing if the switch is possible. Since this is |
| * inherently tricky driver may decide to disconnect an interface later |
| * with cfg80211_stop_iface(). This doesn't mean driver can accept |
| * everything. It should do it's best to verify requests and reject them |
| * as soon as possible. |
| * |
| * @set_qos_map: Set QoS mapping information to the driver |
| * |
| * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the |
| * given interface This is used e.g. for dynamic HT 20/40 MHz channel width |
| * changes during the lifetime of the BSS. |
| * |
| * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device |
| * with the given parameters; action frame exchange has been handled by |
| * userspace so this just has to modify the TX path to take the TS into |
| * account. |
| * If the admitted time is 0 just validate the parameters to make sure |
| * the session can be created at all; it is valid to just always return |
| * success for that but that may result in inefficient behaviour (handshake |
| * with the peer followed by immediate teardown when the addition is later |
| * rejected) |
| * @del_tx_ts: remove an existing TX TS |
| * |
| * @join_ocb: join the OCB network with the specified parameters |
| * (invoked with the wireless_dev mutex held) |
| * @leave_ocb: leave the current OCB network |
| * (invoked with the wireless_dev mutex held) |
| * |
| * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver |
| * is responsible for continually initiating channel-switching operations |
| * and returning to the base channel for communication with the AP. |
| * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both |
| * peers must be on the base channel when the call completes. |
| * @start_nan: Start the NAN interface. |
| * @stop_nan: Stop the NAN interface. |
| * @add_nan_func: Add a NAN function. Returns negative value on failure. |
| * On success @nan_func ownership is transferred to the driver and |
| * it may access it outside of the scope of this function. The driver |
| * should free the @nan_func when no longer needed by calling |
| * cfg80211_free_nan_func(). |
| * On success the driver should assign an instance_id in the |
| * provided @nan_func. |
| * @del_nan_func: Delete a NAN function. |
| * @nan_change_conf: changes NAN configuration. The changed parameters must |
| * be specified in @changes (using &enum cfg80211_nan_conf_changes); |
| * All other parameters must be ignored. |
