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.

1858 * DOC: Scanning and BSS list handling
1859 *
1860 * The scanning process itself is fairly simple, but cfg80211 offers quite
1861 * a bit of helper functionality. To start a scan, the scan operation will
1862 * be invoked with a scan definition. This scan definition contains the
1863 * channels to scan, and the SSIDs to send probe requests for (including the
1864 * wildcard, if desired). A passive scan is indicated by having no SSIDs to
1865 * probe. Additionally, a scan request may contain extra information elements
1866 * that should be added to the probe request. The IEs are guaranteed to be
1867 * well-formed, and will not exceed the maximum length the driver advertised
1868 * in the wiphy structure.
1869 *
1870 * When scanning finds a BSS, cfg80211 needs to be notified of that, because
1871 * it is responsible for maintaining the BSS list; the driver should not
1872 * maintain a list itself. For this notification, various functions exist.
1873 *
1874 * Since drivers do not maintain a BSS list, there are also a number of
1875 * functions to search for a BSS and obtain information about it from the
1876 * BSS structure cfg80211 maintains. The BSS list is also made available
1877 * to userspace.

2174 * for use in scan results and similar.
2175 *
Johannes Bergabe37c42010-06-07 11:12:27 +02002176 * @channel: channel this BSS is on
Simon Wunderlichdcd6eac2013-07-08 16:55:49 +02002177 * @scan_width: width of the control channel
Johannes Berg2a519312009-02-10 21:25:55 +01002178 * @bssid: BSSID of the BSS
Johannes Berg2a519312009-02-10 21:25:55 +01002179 * @beacon_interval: the beacon interval as from the frame
2180 * @capability: the capability field in host byte order
Johannes Berg83c7aa12013-02-05 16:51:29 +01002181 * @ies: the information elements (Note that there is no guarantee that these
2182 * are well-formed!); this is a pointer to either the beacon_ies or
2183 * proberesp_ies depending on whether Probe Response frame has been
2184 * received. It is always non-%NULL.

Jouni Malinen34a6edd2010-01-06 16:19:24 +02002189 * @proberesp_ies: the information elements from the last Probe Response frame
Johannes Berg776b3582013-02-01 02:06:18 +01002190 * @hidden_beacon_bss: in case this BSS struct represents a probe response from
2191 * a BSS that hides the SSID in its beacon, this points to the BSS struct
2192 * that holds the beacon data. @beacon_ies is still valid, of course, and

2197 * (multi-BSSID support)

3417 * frame instead of Association Request frame.
3418 * The connect function can also be used to request the driver to perform a
3419 * specific roam when connected to an ESS. In that case, the prev_bssid

Johannes Berg5be83de2009-11-19 00:56:28 +01003967 * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this
3968 * wiphy at all
3969 * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled
3970 * by default -- this flag will be set depending on the kernel's default
3971 * on wiphy_new(), but can be changed by the driver if it has a good
3972 * reason to override the default
Johannes Berg9bc383d2009-11-19 11:55:19 +01003973 * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station
Manikanta Pubbisetty33d915d2019-05-08 14:55:33 +05303974 * on a VLAN interface). This flag also serves an extra purpose of
3975 * supporting 4ADDR AP mode on devices which do not support AP/VLAN iftype.
Johannes Berg9bc383d2009-11-19 11:55:19 +01003976 * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station
Johannes Bergc0692b82010-08-27 14:26:53 +03003977 * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the
3978 * control port protocol ethertype. The device also honours the
3979 * control_port_no_encrypt flag.
Johannes Berge31b8212010-10-05 19:39:30 +02003980 * @WIPHY_FLAG_IBSS_RSN: The device supports IBSS RSN.
Javier Cardona15d5dda2011-04-07 15:08:28 -07003981 * @WIPHY_FLAG_MESH_AUTH: The device supports mesh authentication by routing
3982 * auth frames to userspace. See @NL80211_MESH_SETUP_USERSPACE_AUTH.
Vivek Natarajanf4b34b52011-08-29 14:23:03 +05303983 * @WIPHY_FLAG_SUPPORTS_FW_ROAM: The device supports roaming feature in the
3984 * firmware.
Eliad Pellercedb5412011-08-31 11:29:43 +03003985 * @WIPHY_FLAG_AP_UAPSD: The device supports uapsd on AP.
Arik Nemtsov109086c2011-09-28 14:12:50 +03003986 * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation.
3987 * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z)
3988 * link setup/discovery operations internally. Setup, discovery and
3989 * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT
3990 * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be
3991 * used for asking the driver/firmware to perform a TDLS operation.
Johannes Berg562a7482011-11-07 12:39:33 +01003992 * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME
Johannes Berg5e760232011-11-04 11:18:17 +01003993 * @WIPHY_FLAG_REPORTS_OBSS: the device will report beacons from other BSSes
3994 * when there are virtual interfaces in AP mode by calling
3995 * cfg80211_report_obss_beacon().
Arik Nemtsov87bbbe22011-11-10 11:28:55 +02003996 * @WIPHY_FLAG_AP_PROBE_RESP_OFFLOAD: When operating as an AP, the device
3997 * responds to probe-requests in hardware.
Johannes Berg7c4ef712011-11-18 15:33:48 +01003998 * @WIPHY_FLAG_OFFCHAN_TX: Device supports direct off-channel TX.
3999 * @WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL: Device supports remain-on-channel call.
Simon Wunderlich2f301ab2013-05-16 13:00:28 +02004000 * @WIPHY_FLAG_SUPPORTS_5_10_MHZ: Device supports 5 MHz and 10 MHz channels.
Simon Wunderlich16ef1fe2013-07-11 16:09:05 +02004001 * @WIPHY_FLAG_HAS_CHANNEL_SWITCH: Device supports channel switch in
