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.

1392 *
1393 * The scanning process itself is fairly simple, but cfg80211 offers quite
1394 * a bit of helper functionality. To start a scan, the scan operation will
1395 * be invoked with a scan definition. This scan definition contains the
1396 * channels to scan, and the SSIDs to send probe requests for (including the
1397 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1398 * probe. Additionally, a scan request may contain extra information elements
1399 * that should be added to the probe request. The IEs are guaranteed to be
1400 * well-formed, and will not exceed the maximum length the driver advertised
1401 * in the wiphy structure.
1402 *
1403 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1404 * it is responsible for maintaining the BSS list; the driver should not
1405 * maintain a list itself. For this notification, various functions exist.
1406 *
1407 * Since drivers do not maintain a BSS list, there are also a number of
1408 * functions to search for a BSS and obtain information about it from the
1409 * BSS structure cfg80211 maintains. The BSS list is also made available
1410 * to userspace.

1590 * @capability: the capability field in host byte order
Johannes Berg83c7aa12013-02-05 16:51:29 +01001591 * @ies: the information elements (Note that there is no guarantee that these
1592 * are well-formed!); this is a pointer to either the beacon_ies or
1593 * proberesp_ies depending on whether Probe Response frame has been
1594 * received. It is always non-%NULL.

2364 * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
2365 * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
2366 * reject TX/RX mask combinations they cannot support by returning -EINVAL
2367 * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
2368 *
2369 * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).

2372 * @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
Johannes Berg7f6cf312011-11-04 11:18:15 +01002373 *
2374 * @probe_client: probe an associated client, must return a cookie that it
2375 * later passes to cfg80211_probe_status().
Simon Wunderlich1d9d9212011-11-18 14:20:43 +01002376 *
2377 * @set_noack_map: Set the NoAck Map for the TIDs.
Ben Greeard6199212012-04-23 12:50:29 -07002378 *
Johannes Berg5b7ccaf2012-07-12 19:45:08 +02002379 * @get_channel: Get the current operating channel for the virtual interface.
2380 * For monitor interfaces, it should return %NULL unless there's a single
2381 * current monitoring channel.
Johannes Berg98104fde2012-06-16 00:19:54 +02002382 *
2383 * @start_p2p_device: Start the given P2P device.
2384 * @stop_p2p_device: Stop the given P2P device.
Vasanthakumar Thiagarajan77765ea2013-01-18 11:18:45 +05302385 *
2386 * @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
2387 * Parameters include ACL policy, an array of MAC address of stations
2388 * and the number of MAC addresses. If there is already a list in driver
2389 * this new list replaces the existing one. Driver has to clear its ACL
2390 * when number of MAC addresses entries is passed as 0. Drivers which
2391 * advertise the support for MAC based ACL have to implement this callback.
Simon Wunderlich04f39042013-02-08 18:16:19 +01002392 *
2393 * @start_radar_detection: Start radar detection in the driver.
Jouni Malinen8bf24292013-03-25 11:15:59 +02002394 *
2395 * @update_ft_ies: Provide updated Fast BSS Transition information to the
2396 * driver. If the SME is in the driver/firmware, this information can be
2397 * used in building Authentication and Reassociation Request frames.
Arend van Spriel5de17982013-04-18 15:49:00 +02002398 *
2399 * @crit_proto_start: Indicates a critical protocol needs more link reliability
2400 * for a given duration (milliseconds). The protocol is provided so the
2401 * driver can take the most appropriate actions.
2402 * @crit_proto_stop: Indicates critical protocol no longer needs increased link
2403 * reliability. This operation can not fail.
Amitkumar Karwarbe29b992013-06-28 11:51:26 -07002404 * @set_coalesce: Set coalesce parameters.
Simon Wunderlich16ef1fe2013-07-11 16:09:05 +02002405 *
Michal Kazior97dc94f2014-06-25 12:35:10 +02002406 * @channel_switch: initiate channel-switch procedure (with CSA). Driver is
2407 * responsible for veryfing if the switch is possible. Since this is
2408 * inherently tricky driver may decide to disconnect an interface later
2409 * with cfg80211_stop_iface(). This doesn't mean driver can accept
2410 * everything. It should do it's best to verify requests and reject them
2411 * as soon as possible.
Kyeyoon Parkfa9ffc72013-12-16 23:01:30 -08002412 *
2413 * @set_qos_map: Set QoS mapping information to the driver
Jouni Malinene16821b2014-04-28 11:22:08 +03002414 *
2415 * @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
2416 * given interface This is used e.g. for dynamic HT 20/40 MHz channel width
2417 * changes during the lifetime of the BSS.
Johannes Berg960d01a2014-09-09 22:55:35 +03002418 *
2419 * @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
2420 * with the given parameters; action frame exchange has been handled by
2421 * userspace so this just has to modify the TX path to take the TS into
2422 * account.
2423 * If the admitted time is 0 just validate the parameters to make sure
2424 * the session can be created at all; it is valid to just always return
2425 * success for that but that may result in inefficient behaviour (handshake
2426 * with the peer followed by immediate teardown when the addition is later
2427 * rejected)
2428 * @del_tx_ts: remove an existing TX TS
Rostislav Lisovy6e0bd6c2014-11-03 10:33:18 +01002429 *
2430 * @join_ocb: join the OCB network with the specified parameters
2431 * (invoked with the wireless_dev mutex held)
2432 * @leave_ocb: leave the current OCB network
2433 * (invoked with the wireless_dev mutex held)
Arik Nemtsov1057d352014-11-19 12:54:26 +02002434 *
2435 * @tdls_channel_switch: Start channel-switching with a TDLS peer. The driver
2436 * is responsible for continually initiating channel-switching operations
2437 * and returning to the base channel for communication with the AP.
2438 * @tdls_cancel_channel_switch: Stop channel-switching with a TDLS peer. Both
2439 * peers must be on the base channel when the call completes.

4364 * Test mode is a set of utility functions to allow drivers to
4365 * interact with driver-specific tools to aid, for instance,
4366 * factory programming.
4367 *
4368 * This chapter describes how drivers interact with it, for more
4369 * information see the nl80211 book's chapter on it.

Johannes Bergaff89a92009-07-01 21:26:51 +02004373 * cfg80211_testmode_alloc_reply_skb - allocate testmode reply

4375 * @approxlen: an upper bound of the length of the data that will
4376 * be put into the skb
4377 *
4378 * This function allocates and pre-fills an skb for a reply to
4379 * the testmode command. Since it is intended for a reply, calling
4380 * it outside of the @testmode_cmd operation is invalid.

4383 * a way that any data that is put into the skb (with skb_put(),
4384 * nla_put() or similar) will end up being within the
4385 * %NL80211_ATTR_TESTDATA attribute, so all that needs to be done
4386 * with the skb is adding data for the corresponding userspace tool
4387 * which can then read that data out of the testdata attribute. You
4388 * must not modify the skb in any other way.
Johannes Bergaff89a92009-07-01 21:26:51 +02004389 *
4390 * When done, call cfg80211_testmode_reply() with the skb and return
4391 * its error code as the result of the @testmode_cmd operation.
Yacine Belkadi0ae997d2013-01-12 13:54:14 +01004392 *
