27 * DOC: Introduction
28 *
29 * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
30 * userspace and drivers, and offers some utility functionality associated
31 * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
32 * by all modern wireless drivers in Linux, so that they offer a consistent
33 * API through nl80211. For backward compatibility, cfg80211 also offers
34 * wireless extensions to userspace, but hides them from drivers completely.
35 *
36 * Additionally, cfg80211 contains code to help enforce regulatory spectrum
37 * use restrictions.

42 * DOC: Device registration
43 *
44 * In order for a driver to use cfg80211, it must register the hardware device
45 * with cfg80211. This happens through a number of hardware capability structs
46 * described below.
47 *
48 * The fundamental structure for each device is the 'wiphy', of which each
49 * instance describes a physical wireless device connected to the system. Each
50 * such wiphy can have zero, one, or many virtual interfaces associated with
51 * it, which need to be identified as such by pointing the network interface's
52 * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
53 * the wireless part of the interface, normally this struct is embedded in the
54 * network interface's private data area. Drivers can optionally allow creating
55 * or destroying virtual interfaces on the fly, but without at least one or the
56 * ability to create some the wireless device isn't useful.
57 *
58 * Each wiphy structure contains device capability information, and also has
59 * a pointer to the various operations the driver offers. The definitions and
60 * structures here describe these capabilities in detail.

1364 * DOC: Scanning and BSS list handling
1365 *
1366 * The scanning process itself is fairly simple, but cfg80211 offers quite
1367 * a bit of helper functionality. To start a scan, the scan operation will
1368 * be invoked with a scan definition. This scan definition contains the
1369 * channels to scan, and the SSIDs to send probe requests for (including the
1370 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1371 * probe. Additionally, a scan request may contain extra information elements
1372 * that should be added to the probe request. The IEs are guaranteed to be
1373 * well-formed, and will not exceed the maximum length the driver advertised
1374 * in the wiphy structure.
1375 *
1376 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1377 * it is responsible for maintaining the BSS list; the driver should not
1378 * maintain a list itself. For this notification, various functions exist.
1379 *
1380 * Since drivers do not maintain a BSS list, there are also a number of
1381 * functions to search for a BSS and obtain information about it from the
1382 * BSS structure cfg80211 maintains. The BSS list is also made available
1383 * to userspace.

1560 *
1561 * This structure describes a BSS (which may also be a mesh network)
1562 * for use in scan results and similar.
1563 *
Johannes Bergabe37c42010-06-07 11:12:27 +02001564 * @channel: channel this BSS is on
Simon Wunderlichdcd6eac2013-07-08 16:55:49 +02001565 * @scan_width: width of the control channel
Johannes Berg2a519312009-02-10 21:25:55 +01001566 * @bssid: BSSID of the BSS
Johannes Berg2a519312009-02-10 21:25:55 +01001567 * @beacon_interval: the beacon interval as from the frame
1568 * @capability: the capability field in host byte order
Johannes Berg83c7aa12013-02-05 16:51:29 +01001569 * @ies: the information elements (Note that there is no guarantee that these
1570 * are well-formed!); this is a pointer to either the beacon_ies or
1571 * proberesp_ies depending on whether Probe Response frame has been
1572 * received. It is always non-%NULL.
Jouni Malinen34a6edd2010-01-06 16:19:24 +02001573 * @beacon_ies: the information elements from the last Beacon frame
Johannes Berg776b3582013-02-01 02:06:18 +01001574 * (implementation note: if @hidden_beacon_bss is set this struct doesn't
1575 * own the beacon_ies, but they're just pointers to the ones from the
1576 * @hidden_beacon_bss struct)
Jouni Malinen34a6edd2010-01-06 16:19:24 +02001577 * @proberesp_ies: the information elements from the last Probe Response frame
Johannes Berg776b3582013-02-01 02:06:18 +01001578 * @hidden_beacon_bss: in case this BSS struct represents a probe response from
1579 * a BSS that hides the SSID in its beacon, this points to the BSS struct
1580 * that holds the beacon data. @beacon_ies is still valid, of course, and
1581 * points to the same data as hidden_beacon_bss->beacon_ies in that case.
Johannes Berg77965c92009-02-18 18:45:06 +01001582 * @signal: signal strength value (type depends on the wiphy's signal_type)
Johannes Berg2a519312009-02-10 21:25:55 +01001583 * @priv: private area for driver use, has at least wiphy->bss_priv_size bytes

2369 * advertise the support for MAC based ACL have to implement this callback.
Simon Wunderlich04f39042013-02-08 18:16:19 +01002370 *
2371 * @start_radar_detection: Start radar detection in the driver.
Jouni Malinen8bf24292013-03-25 11:15:59 +02002372 *
2373 * @update_ft_ies: Provide updated Fast BSS Transition information to the
2374 * driver. If the SME is in the driver/firmware, this information can be
2375 * used in building Authentication and Reassociation Request frames.
Arend van Spriel5de17982013-04-18 15:49:00 +02002376 *
2377 * @crit_proto_start: Indicates a critical protocol needs more link reliability
2378 * for a given duration (milliseconds). The protocol is provided so the
2379 * driver can take the most appropriate actions.
2380 * @crit_proto_stop: Indicates critical protocol no longer needs increased link
2381 * reliability. This operation can not fail.
Amitkumar Karwarbe29b992013-06-28 11:51:26 -07002382 * @set_coalesce: Set coalesce parameters.
Simon Wunderlich16ef1fe2013-07-11 16:09:05 +02002383 *
Michal Kazior97dc94f2014-06-25 12:35:10 +02002384 * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
2385 * responsible for veryfing if the switch is possible. Since this is
2386 * inherently tricky driver may decide to disconnect an interface later
2387 * with cfg80211_stop_iface(). This doesn't mean driver can accept
2388 * everything. It should do it's best to verify requests and reject them
2389 * as soon as possible.
Kyeyoon Parkfa9ffc72013-12-16 23:01:30 -08002390 *
2391 * @set_qos_map: Set QoS mapping information to the driver
Jouni Malinene16821b2014-04-28 11:22:08 +03002392 *
2393 * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
2394 * given interface This is used e.g. for dynamic HT 20/40 MHz channel width
2395 * changes during the lifetime of the BSS.
Johannes Berg960d01a2014-09-09 22:55:35 +03002396 *
2397 * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
2398 * with the given parameters; action frame exchange has been handled by
2399 * userspace so this just has to modify the TX path to take the TS into
2400 * account.
2401 * If the admitted time is 0 just validate the parameters to make sure
2402 * the session can be created at all; it is valid to just always return
2403 * success for that but that may result in inefficient behaviour (handshake
2404 * with the peer followed by immediate teardown when the addition is later
2405 * rejected)
2406 * @del_tx_ts: remove an existing TX TS
Rostislav Lisovy6e0bd6c2014-11-03 10:33:18 +01002407 *
2408 * @join_ocb: join the OCB network with the specified parameters
2409 * (invoked with the wireless_dev mutex held)
2410 * @leave_ocb: leave the current OCB network
2411 * (invoked with the wireless_dev mutex held)
Arik Nemtsov1057d352014-11-19 12:54:26 +02002412 *
2413 * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
2414 * is responsible for continually initiating channel-switching operations
2415 * and returning to the base channel for communication with the AP.
2416 * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
2417 * peers must be on the base channel when the call completes.
