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

955 * DOC: Scanning and BSS list handling
957 * The scanning process itself is fairly simple, but cfg80211 offers quite
958 * a bit of helper functionality. To start a scan, the scan operation will
959 * be invoked with a scan definition. This scan definition contains the
960 * channels to scan, and the SSIDs to send probe requests for (including the
961 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
962 * probe. Additionally, a scan request may contain extra information elements
963 * that should be added to the probe request. The IEs are guaranteed to be
964 * well-formed, and will not exceed the maximum length the driver advertised
965 * in the wiphy structure.
967 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
968 * it is responsible for maintaining the BSS list; the driver should not
969 * maintain a list itself. For this notification, various functions exist.
971 * Since drivers do not maintain a BSS list, there are also a number of
972 * functions to search for a BSS and obtain information about it from the
973 * BSS structure cfg80211 maintains. The BSS list is also made available

1418 * on success or a negative error code.
1420 * All operations are currently invoked under rtnl for consistency with the
1421 * wireless extensions but this is subject to reevaluation as soon as this
1422 * code is used more widely and we have a first user without wext.
1424 * @suspend: wiphy device needs to be suspended. The variable @wow will
1425 * be %NULL or contain the enabled Wake-on-Wireless triggers that are
1426 * configured for the device.
1427 * @resume: wiphy device needs to be resumed
1428 * @set_wakeup: Called when WoWLAN is enabled/disabled, use this callback
1429 * to call device_set_wakeup_enable() to enable/disable wakeup from
1432 * @add_virtual_intf: create a new virtual interface with the given name,
1433 * must set the struct wireless_dev's iftype. Beware: You must create

1437 * @del_virtual_intf: remove the virtual interface determined by ifindex.
1439 * @change_virtual_intf: change type/configuration of virtual interface,
1440 * keep the struct wireless_dev's iftype updated.

1443 * when adding a group key.
1445 * @get_key: get information about the key with the given parameters.
1446 * @mac_addr will be %NULL when requesting information for a group
1447 * key. All pointers given to the @callback function need not be valid
1448 * after it returns. This function should return an error if it is
1449 * not possible to retrieve the key, -ENOENT if it doesn't exist.
1451 * @del_key: remove a key given the @mac_addr (%NULL for a group key)
1452 * and @key_index, return -ENOENT if the key doesn't exist.

1465 * @add_station: Add a new station.
1466 * @del_station: Remove a station; @mac may be NULL to remove all stations.
1467 * @change_station: Modify a given station. Note that flags changes are not much
1468 * validated in cfg80211, in particular the auth/assoc/authorized flags
1469 * might come to the driver in invalid combinations -- make sure to check
1470 * them, also against the existing state! Also, supported_rates changes are
1471 * not checked in station mode -- drivers need to reject (or ignore) them
1472 * for anything but TDLS peers.
1473 * @get_station: get station information for the station identified by @mac
1474 * @dump_station: dump station callback -- resume dump at index @idx

1490 * @change_bss: Modify parameters for a given BSS.
1492 * @set_txq_params: Set TX queue parameters
1494 * @libertas_set_mesh_channel: Only for backward compatibility for libertas,
1495 * as it doesn't implement join_mesh and needs to set the channel to
1496 * join the mesh instead.
1498 * @set_monitor_channel: Set the monitor mode channel for the device. If other
1499 * interfaces are active this callback should reject the configuration.
1500 * If no interfaces are active or the device is down, the channel should
1501 * be stored for when a monitor interface becomes active.
1502 * @get_channel: Get the current operating channel, should return %NULL if
1503 * there's no single defined operating channel if for example the
1504 * device implements channel hopping for multi-channel virtual interfaces.
1506 * @scan: Request to do a scan. If returning zero, the scan request is given
1507 * the driver, and will be valid until passed to cfg80211_scan_done().
1508 * For scan results, call cfg80211_inform_bss(); you can call this outside
1509 * the scan/scan_done bracket too.
1511 * @auth: Request to authenticate with the specified peer
1512 * @assoc: Request to (re)associate with the specified peer
1513 * @deauth: Request to deauthenticate from the specified peer
1514 * @disassoc: Request to disassociate from the specified peer
1516 * @connect: Connect to the ESS with the specified parameters. When connected,
1517 * call cfg80211_connect_result() with status code %WLAN_STATUS_SUCCESS.
1518 * If the connection fails for some reason, call cfg80211_connect_result()
1519 * with the status from the AP.
1520 * @disconnect: Disconnect from the BSS/ESS.
1522 * @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
1523 * cfg80211_ibss_joined(), also call that function when changing BSSID due
1525 * @leave_ibss: Leave the IBSS.
1527 * @set_wiphy_params: Notify that wiphy parameters have changed;
1528 * @changed bitfield (see &enum wiphy_params_flags) describes which values
1529 * have changed. The actual parameter values are available in
1530 * struct wiphy. If returning an error, no value should be changed.
1532 * @set_tx_power: set the transmit power according to the parameters,
1533 * the power passed is in mBm, to get dBm use MBM_TO_DBM().
1534 * @get_tx_power: store the current TX power into the dbm variable;
1535 * return 0 if successful
1537 * @set_wds_peer: set the WDS peer for a WDS interface
1539 * @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
1540 * functions to adjust rfkill hw state
1542 * @dump_survey: get site survey information.
1544 * @remain_on_channel: Request the driver to remain awake on the specified
1545 * channel for the specified duration to complete an off-channel
1546 * operation (e.g., public action frame exchange). When the driver is
1547 * ready on the requested channel, it must indicate this with an event
1548 * notification by calling cfg80211_ready_on_channel().
1549 * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
1550 * This allows the operation to be terminated prior to timeout based on
1551 * the duration value.
1552 * @mgmt_tx: Transmit a management frame.
1553 * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
1554 * frame on another channel
1556 * @testmode_cmd: run a test mode command
1557 * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
1558 * used by the function, but 0 and 1 must not be touched. Additionally,
1559 * return error codes other than -ENOBUFS and -ENOENT will terminate the
1560 * dump and return to userspace with an error, so be careful. If any data
1561 * was passed in from userspace then the data/len arguments will be present
1562 * and point to the data contained in %NL80211_ATTR_TESTDATA.
1564 * @set_bitrate_mask: set the bitrate mask configuration
1566 * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
1567 * devices running firmwares capable of generating the (re) association
1568 * RSN IE. It allows for faster roaming between WPA2 BSSIDs.
1569 * @del_pmksa: Delete a cached PMKID.
1570 * @flush_pmksa: Flush all cached PMKIDs.
1571 * @set_power_mgmt: Configure WLAN power management. A timeout value of -1
1572 * allows the driver to adjust the dynamic ps timeout value.
1573 * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
1574 * @sched_scan_start: Tell the driver to start a scheduled scan.
1575 * @sched_scan_stop: Tell the driver to stop an ongoing scheduled
1576 * scan. The driver_initiated flag specifies whether the driver
1577 * itself has informed that the scan has stopped.
1579 * @mgmt_frame_register: Notify driver that a management frame type was
1580 * registered. Note that this callback may not sleep, and cannot run
1581 * concurrently with itself.
1583 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
1584 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
1585 * reject TX/RX mask combinations they cannot support by returning -EINVAL
1586 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
1588 * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
1590 * @set_ringparam: Set tx and rx ring sizes.
1592 * @get_ringparam: Get tx and rx ring current and maximum sizes.
1594 * @tdls_mgmt: Transmit a TDLS management frame.
1595 * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
1597 * @probe_client: probe an associated client, must return a cookie that it
1598 * later passes to cfg80211_probe_status().
1600 * @set_noack_map: Set the NoAck Map for the TIDs.
1602 * @get_et_sset_count: Ethtool API to get string-set count.
1603 * See @ethtool_ops.get_sset_count
1605 * @get_et_stats: Ethtool API to get a set of u64 stats.
1606 * See @ethtool_ops.get_ethtool_stats
1608 * @get_et_strings: Ethtool API to get a set of strings to describe stats
1609 * and perhaps other supported types of ethtool data-sets.

3064 * RFkill integration in cfg80211 is almost invisible to drivers,
3065 * as cfg80211 automatically registers an rfkill instance for each
3066 * wireless device it knows about. Soft kill is also translated
3067 * into disconnecting and turning all interfaces off, drivers are
3068 * expected to turn off the device when all interfaces are down.
3070 * However, devices may have a hard RFkill line, in which case they
3071 * also need to interact with the rfkill subsystem, via cfg80211.
3072 * They can do this with a few helper functions documented here.
