26 * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
27 * userspace and drivers, and offers some utility functionality associated
28 * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
29 * by all modern wireless drivers in Linux, so that they offer a consistent
30 * API through nl80211. For backward compatibility, cfg80211 also offers
31 * wireless extensions to userspace, but hides them from drivers completely.
33 * Additionally, cfg80211 contains code to help enforce regulatory spectrum
39 * DOC: Device registration
41 * In order for a driver to use cfg80211, it must register the hardware device
42 * with cfg80211. This happens through a number of hardware capability structs
45 * The fundamental structure for each device is the 'wiphy', of which each
46 * instance describes a physical wireless device connected to the system. Each
47 * such wiphy can have zero, one, or many virtual interfaces associated with
48 * it, which need to be identified as such by pointing the network interface's
49 * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
50 * the wireless part of the interface, normally this struct is embedded in the
51 * network interface's private data area. Drivers can optionally allow creating
52 * or destroying virtual interfaces on the fly, but without at least one or the
53 * ability to create some the wireless device isn't useful.
55 * Each wiphy structure contains device capability information, and also has
56 * a pointer to the various operations the driver offers. The definitions and
57 * structures here describe these capabilities in detail.

843 * DOC: Scanning and BSS list handling
845 * The scanning process itself is fairly simple, but cfg80211 offers quite
846 * a bit of helper functionality. To start a scan, the scan operation will
847 * be invoked with a scan definition. This scan definition contains the
848 * channels to scan, and the SSIDs to send probe requests for (including the
849 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
850 * probe. Additionally, a scan request may contain extra information elements
851 * that should be added to the probe request. The IEs are guaranteed to be
852 * well-formed, and will not exceed the maximum length the driver advertised
853 * in the wiphy structure.
855 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
856 * it is responsible for maintaining the BSS list; the driver should not
857 * maintain a list itself. For this notification, various functions exist.
859 * Since drivers do not maintain a BSS list, there are also a number of
860 * functions to search for a BSS and obtain information about it from the
861 * BSS structure cfg80211 maintains. The BSS list is also made available

1299 * on success or a negative error code.
1301 * All operations are currently invoked under rtnl for consistency with the
1302 * wireless extensions but this is subject to reevaluation as soon as this
1303 * code is used more widely and we have a first user without wext.
1305 * @suspend: wiphy device needs to be suspended. The variable @wow will
1306 * be %NULL or contain the enabled Wake-on-Wireless triggers that are
1307 * configured for the device.
1308 * @resume: wiphy device needs to be resumed
1310 * @add_virtual_intf: create a new virtual interface with the given name,
1311 * must set the struct wireless_dev's iftype. Beware: You must create
1312 * the new netdev in the wiphy's network namespace! Returns the netdev,
1315 * @del_virtual_intf: remove the virtual interface determined by ifindex.
1317 * @change_virtual_intf: change type/configuration of virtual interface,
1318 * keep the struct wireless_dev's iftype updated.

1321 * when adding a group key.
1323 * @get_key: get information about the key with the given parameters.
1324 * @mac_addr will be %NULL when requesting information for a group
1325 * key. All pointers given to the @callback function need not be valid
1326 * after it returns. This function should return an error if it is
1327 * not possible to retrieve the key, -ENOENT if it doesn't exist.
1329 * @del_key: remove a key given the @mac_addr (%NULL for a group key)
1330 * and @key_index, return -ENOENT if the key doesn't exist.
1332 * @set_default_key: set the default key on an interface
1334 * @set_default_mgmt_key: set the default management frame key on an interface
1336 * @set_rekey_data: give the data necessary for GTK rekeying to the driver

1359 * @get_mesh_config: Get the current mesh configuration
1361 * @update_mesh_config: Update mesh parameters on a running mesh.
1362 * The mask is a bitfield which tells us which parameters to
1363 * set, and which to leave alone.
1365 * @change_bss: Modify parameters for a given BSS.
1367 * @set_txq_params: Set TX queue parameters
1369 * @set_channel: Set channel for a given wireless interface. Some devices
1370 * may support multi-channel operation (by channel hopping) so cfg80211
1371 * doesn't verify much. Note, however, that the passed netdev may be
1372 * %NULL as well if the user requested changing the channel for the
1373 * device itself, or for a monitor interface.
1374 * @get_channel: Get the current operating channel, should return %NULL if
1375 * there's no single defined operating channel if for example the
1376 * device implements channel hopping for multi-channel virtual interfaces.
1378 * @scan: Request to do a scan. If returning zero, the scan request is given
1379 * the driver, and will be valid until passed to cfg80211_scan_done().
1380 * For scan results, call cfg80211_inform_bss(); you can call this outside
1381 * the scan/scan_done bracket too.
1383 * @auth: Request to authenticate with the specified peer
1384 * @assoc: Request to (re)associate with the specified peer
1385 * @deauth: Request to deauthenticate from the specified peer
1386 * @disassoc: Request to disassociate from the specified peer
1388 * @connect: Connect to the ESS with the specified parameters. When connected,
1389 * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS.
1390 * If the connection fails for some reason, call cfg80211_connect_result()
1391 * with the status from the AP.
1392 * @disconnect: Disconnect from the BSS/ESS.
1394 * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
1395 * cfg80211_ibss_joined(), also call that function when changing BSSID due
1397 * @leave_ibss: Leave the IBSS.
1399 * @set_wiphy_params: Notify that wiphy parameters have changed;
1400 * @changed bitfield (see &enum wiphy_params_flags) describes which values
1401 * have changed. The actual parameter values are available in
1402 * struct wiphy. If returning an error, no value should be changed.
1404 * @set_tx_power: set the transmit power according to the parameters
1405 * @get_tx_power: store the current TX power into the dbm variable;
1406 * return 0 if successful
1408 * @set_wds_peer: set the WDS peer for a WDS interface
1410 * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
1411 * functions to adjust rfkill hw state
1413 * @dump_survey: get site survey information.
1415 * @remain_on_channel: Request the driver to remain awake on the specified
1416 * channel for the specified duration to complete an off-channel
1417 * operation (e.g., public action frame exchange). When the driver is
1418 * ready on the requested channel, it must indicate this with an event
1419 * notification by calling cfg80211_ready_on_channel().
1420 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
1421 * This allows the operation to be terminated prior to timeout based on
1422 * the duration value.
1423 * @mgmt_tx: Transmit a management frame.
1424 * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
1425 * frame on another channel
1427 * @testmode_cmd: run a test mode command
1428 * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
1429 * used by the function, but 0 and 1 must not be touched. Additionally,
1430 * return error codes other than -ENOBUFS and -ENOENT will terminate the
1431 * dump and return to userspace with an error, so be careful. If any data
1432 * was passed in from userspace then the data/len arguments will be present
1433 * and point to the data contained in %NL80211_ATTR_TESTDATA.
1435 * @set_bitrate_mask: set the bitrate mask configuration
1437 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
1438 * devices running firmwares capable of generating the (re) association
1439 * RSN IE. It allows for faster roaming between WPA2 BSSIDs.
1440 * @del_pmksa: Delete a cached PMKID.
1441 * @flush_pmksa: Flush all cached PMKIDs.
1442 * @set_power_mgmt: Configure WLAN power management. A timeout value of -1
1443 * allows the driver to adjust the dynamic ps timeout value.
1444 * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
1445 * @sched_scan_start: Tell the driver to start a scheduled scan.
1446 * @sched_scan_stop: Tell the driver to stop an ongoing scheduled
1447 * scan. The driver_initiated flag specifies whether the driver
1448 * itself has informed that the scan has stopped.
1450 * @mgmt_frame_register: Notify driver that a management frame type was
1451 * registered. Note that this callback may not sleep, and cannot run
1452 * concurrently with itself.
1454 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
1455 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
1456 * reject TX/RX mask combinations they cannot support by returning -EINVAL
1457 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
1459 * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
1461 * @set_ringparam: Set tx and rx ring sizes.
1463 * @get_ringparam: Get tx and rx ring current and maximum sizes.
1465 * @tdls_mgmt: Transmit a TDLS management frame.
1466 * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
1468 * @probe_client: probe an associated client, must return a cookie that it
1469 * later passes to cfg80211_probe_status().
1471 * @set_noack_map: Set the NoAck Map for the TIDs.

1686 * ignore regulatory domain settings until it gets its own regulatory
1687 * domain via its regulatory_hint() unless the regulatory hint is
1688 * from a country IE. After its gets its own regulatory domain it will

1711 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
1712 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
1713 * control port protocol ethertype. The device also honours the
1714 * control_port_no_encrypt flag.
1715 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.
1716 * @WIPHY_FLAG_MESH_AUTH: The device supports mesh authentication by routing

2898 * DOC: RFkill integration
2900 * RFkill integration in cfg80211 is almost invisible to drivers,
2901 * as cfg80211 automatically registers an rfkill instance for each
2902 * wireless device it knows about. Soft kill is also translated
2903 * into disconnecting and turning all interfaces off, drivers are
2904 * expected to turn off the device when all interfaces are down.
2906 * However, devices may have a hard RFkill line, in which case they
2907 * also need to interact with the rfkill subsystem, via cfg80211.
2908 * They can do this with a few helper functions documented here.
2912 * wiphy_rfkill_set_hw_state - notify cfg80211 about hw block state

2956 * needs to be done with the skb is adding data for the corresponding
2957 * userspace tool which can then read that data out of the testdata
2958 * attribute. You must not modify the skb in any other way.
