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

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

1197 * DOC: Scanning and BSS list handling
1198 *
1199 * The scanning process itself is fairly simple, but cfg80211 offers quite
1200 * a bit of helper functionality. To start a scan, the scan operation will
1201 * be invoked with a scan definition. This scan definition contains the
1202 * channels to scan, and the SSIDs to send probe requests for (including the
1203 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1204 * probe. Additionally, a scan request may contain extra information elements
1205 * that should be added to the probe request. The IEs are guaranteed to be
1206 * well-formed, and will not exceed the maximum length the driver advertised
1207 * in the wiphy structure.
1208 *
1209 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1210 * it is responsible for maintaining the BSS list; the driver should not
1211 * maintain a list itself. For this notification, various functions exist.
1212 *
1213 * Since drivers do not maintain a BSS list, there are also a number of
1214 * functions to search for a BSS and obtain information about it from the
1215 * BSS structure cfg80211 maintains. The BSS list is also made available
1216 * to userspace.

1526 * @bssid: Fixed BSSID requested, maybe be %NULL, if set do not
1527 * search for IBSSs with a different BSSID.
Johannes Berg683b6d32012-11-08 21:25:48 +01001528 * @chandef: defines the channel to use if no other IBSS to join can be found
Johannes Berg04a773a2009-04-19 21:24:32 +02001529 * @channel_fixed: The channel should be fixed -- do not search for
1530 * IBSSs to join on other channels.
1531 * @ie: information element(s) to include in the beacon
1532 * @ie_len: length of that
Johannes Berg8e30bc52009-04-22 17:45:38 +02001533 * @beacon_interval: beacon interval to use

Johannes Bergd3236552009-04-20 14:31:42 +02002257 * has its own custom regulatory domain and cannot identify the
2258 * ISO / IEC 3166 alpha2 it belongs to. When this is enabled
2259 * we will disregard the first regulatory hint (when the
2260 * initiator is %REGDOM_SET_BY_CORE).
Johannes Berg5be83de2009-11-19 00:56:28 +01002261 * @WIPHY_FLAG_STRICT_REGULATORY: tells us the driver for this device will
2262 * ignore regulatory domain settings until it gets its own regulatory
Luis R. Rodriguez749b5272010-10-20 10:18:54 -07002263 * domain via its regulatory_hint() unless the regulatory hint is
2264 * from a country IE. After its gets its own regulatory domain it will
2265 * only allow further regulatory domain settings to further enhance
2266 * compliance. For example if channel 13 and 14 are disabled by this
2267 * regulatory domain no user regulatory domain can enable these channels
2268 * at a later time. This can be used for devices which do not have
2269 * calibration information guaranteed for frequencies or settings

2272 * will be followed.
Johannes Berg5be83de2009-11-19 00:56:28 +01002273 * @WIPHY_FLAG_DISABLE_BEACON_HINTS: enable this if your driver needs to ensure
2274 * that passive scan flags and beaconing flags may not be lifted by
2275 * cfg80211 due to regulatory beacon hints. For more information on beacon
Luis R. Rodriguez37184242009-07-30 17:43:48 -07002276 * hints read the documenation for regulatory_hint_found_beacon()
Johannes Berg5be83de2009-11-19 00:56:28 +01002277 * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this
2278 * wiphy at all
2279 * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
2280 * by default -- this flag will be set depending on the kernel's default
2281 * on wiphy_new(), but can be changed by the driver if it has a good
2282 * reason to override the default
Johannes Berg9bc383d2009-11-19 11:55:19 +01002283 * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station
2284 * on a VLAN interface)
2285 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
Johannes Bergc0692b82010-08-27 14:26:53 +03002286 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
2287 * control port protocol ethertype. The device also honours the
2288 * control_port_no_encrypt flag.
Johannes Berge31b8212010-10-05 19:39:30 +02002289 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.
Javier Cardona15d5dda2011-04-07 15:08:28 -07002290 * @WIPHY_FLAG_MESH_AUTH: The device supports mesh authentication by routing
2291 * auth frames to userspace. See @NL80211_MESH_SETUP_USERSPACE_AUTH.
Randy Dunlap1ba01452011-05-22 17:16:20 -07002292 * @WIPHY_FLAG_SUPPORTS_SCHED_SCAN: The device supports scheduled scans.
Vivek Natarajanf4b34b52011-08-29 14:23:03 +05302293 * @WIPHY_FLAG_SUPPORTS_FW_ROAM: The device supports roaming feature in the

Eliad Pellercedb5412011-08-31 11:29:43 +03002295 * @WIPHY_FLAG_AP_UAPSD: The device supports uapsd on AP.
Arik Nemtsov109086c2011-09-28 14:12:50 +03002296 * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation.
2297 * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z)
2298 * link setup/discovery operations internally. Setup, discovery and
2299 * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT
2300 * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be
2301 * used for asking the driver/firmware to perform a TDLS operation.
Johannes Berg562a7482011-11-07 12:39:33 +01002302 * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME
Johannes Berg5e7602302011-11-04 11:18:17 +01002303 * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes
2304 * when there are virtual interfaces in AP mode by calling
2305 * cfg80211_report_obss_beacon().
Arik Nemtsov87bbbe22011-11-10 11:28:55 +02002306 * @WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD: When operating as an AP, the device
2307 * responds to probe-requests in hardware.
Johannes Berg7c4ef712011-11-18 15:33:48 +01002308 * @WIPHY_FLAG_OFFCHAN_TX: Device supports direct off-channel TX.

3563 *
3564 * RFkill integration in cfg80211 is almost invisible to drivers,
3565 * as cfg80211 automatically registers an rfkill instance for each
3566 * wireless device it knows about. Soft kill is also translated
3567 * into disconnecting and turning all interfaces off, drivers are
3568 * expected to turn off the device when all interfaces are down.
3569 *
3570 * However, devices may have a hard RFkill line, in which case they
3571 * also need to interact with the rfkill subsystem, via cfg80211.
3572 * They can do this with a few helper functions documented here.
