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. | |

1329 | * | |
1330 | * The scanning process itself is fairly simple, but cfg80211 offers quite | |
1331 | * a bit of helper functionality. To start a scan, the scan operation will | |
1332 | * be invoked with a scan definition. This scan definition contains the | |
1333 | * channels to scan, and the SSIDs to send probe requests for (including the | |
1334 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to | |
1335 | * probe. Additionally, a scan request may contain extra information elements | |
1336 | * that should be added to the probe request. The IEs are guaranteed to be | |
1337 | * well-formed, and will not exceed the maximum length the driver advertised | |
1338 | * in the wiphy structure. | |
1339 | * | |
1340 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because | |
1341 | * it is responsible for maintaining the BSS list; the driver should not | |
1342 | * maintain a list itself. For this notification, various functions exist. | |
1343 | * | |
1344 | * Since drivers do not maintain a BSS list, there are also a number of | |
1345 | * functions to search for a BSS and obtain information about it from the | |
1346 | * BSS structure cfg80211 maintains. The BSS list is also made available | |
1347 | * to userspace. | |

2073 | * @get_key: get information about the key with the given parameters. | |
2074 | * @mac_addr will be %NULL when requesting information for a group | |
2075 | * key. All pointers given to the @callback function need not be valid | |
2076 | * after it returns. This function should return an error if it is | |
2077 | * not possible to retrieve the key, -ENOENT if it doesn't exist. | |
2078 | * | |
2079 | * @del_key: remove a key given the @mac_addr (%NULL for a group key) | |

2092 | * | |
2093 | * @add_station: Add a new station. | |
2094 | * @del_station: Remove a station; @mac may be NULL to remove all stations. | |
2095 | * @change_station: Modify a given station. Note that flags changes are not much | |
2096 | * validated in cfg80211, in particular the auth/assoc/authorized flags | |
2097 | * might come to the driver in invalid combinations -- make sure to check | |
2098 | * them, also against the existing state! Drivers must call | |
2099 | * cfg80211_check_station_change() to validate the information. | |
2100 | * @get_station: get station information for the station identified by @mac | |
2101 | * @dump_station: dump station callback -- resume dump at index @idx | |

2122 | * | |
2123 | * @libertas_set_mesh_channel: Only for backward compatibility for libertas, | |
2124 | * as it doesn't implement join_mesh and needs to set the channel to | |
2125 | * join the mesh instead. | |
2126 | * | |
2127 | * @set_monitor_channel: Set the monitor mode channel for the device. If other | |
2128 | * interfaces are active this callback should reject the configuration. | |
2129 | * If no interfaces are active or the device is down, the channel should | |
2130 | * be stored for when a monitor interface becomes active. | |
2131 | * | |
2132 | * @scan: Request to do a scan. If returning zero, the scan request is given | |
2133 | * the driver, and will be valid until passed to cfg80211_scan_done(). | |
2134 | * For scan results, call cfg80211_inform_bss(); you can call this outside | |
2135 | * the scan/scan_done bracket too. | |

2149 | * with the status from the AP. | |
2150 | * (invoked with the wireless_dev mutex held) | |
2151 | * @disconnect: Disconnect from the BSS/ESS. | |
2152 | * (invoked with the wireless_dev mutex held) | |

2162 | * MESH mode) | |
2163 | * | |
2164 | * @set_wiphy_params: Notify that wiphy parameters have changed; | |
2165 | * @changed bitfield (see &enum wiphy_params_flags) describes which values | |
2166 | * have changed. The actual parameter values are available in | |
2167 | * struct wiphy. If returning an error, no value should be changed. | |
2168 | * | |
2169 | * @set_tx_power: set the transmit power according to the parameters, | |
2170 | * the power passed is in mBm, to get dBm use MBM_TO_DBM(). The | |
2171 | * wdev may be %NULL if power was set for the wiphy, and will | |
2172 | * always be %NULL unless the driver supports per-vif TX power | |
2173 | * (as advertised by the nl80211 feature flag.) | |
2174 | * @get_tx_power: store the current TX power into the dbm variable; | |
2175 | * return 0 if successful | |

2181 | * | |
2182 | * @dump_survey: get site survey information. | |
2183 | * | |
2184 | * @remain_on_channel: Request the driver to remain awake on the specified | |
2185 | * channel for the specified duration to complete an off-channel | |
2186 | * operation (e.g., public action frame exchange). When the driver is | |
2187 | * ready on the requested channel, it must indicate this with an event | |
2188 | * notification by calling cfg80211_ready_on_channel(). | |
2189 | * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. | |
2190 | * This allows the operation to be terminated prior to timeout based on | |
2191 | * the duration value. | |
2192 | * @mgmt_tx: Transmit a management frame. | |
2193 | * @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management | |
2194 | * frame on another channel | |

2197 | * @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be | |
2198 | * used by the function, but 0 and 1 must not be touched. Additionally, | |
2199 | * return error codes other than -ENOBUFS and -ENOENT will terminate the | |
2200 | * dump and return to userspace with an error, so be careful. If any data | |
2201 | * was passed in from userspace then the data/len arguments will be present | |
2202 | * and point to the data contained in %NL80211_ATTR_TESTDATA. | |
2203 | * | |
2204 | * @set_bitrate_mask: set the bitrate mask configuration | |
2205 | * | |
2206 | * @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac | |
2207 | * devices running firmwares capable of generating the (re) association | |
2208 | * RSN IE. It allows for faster roaming between WPA2 BSSIDs. | |
2209 | * @del_pmksa: Delete a cached PMKID. | |
2210 | * @flush_pmksa: Flush all cached PMKIDs. | |
2211 | * @set_power_mgmt: Configure WLAN power management. A timeout value of -1 | |
2212 | * allows the driver to adjust the dynamic ps timeout value. | |
2213 | * @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold. | |
2214 | * @set_cqm_txe_config: Configure connection quality monitor TX error | |
2215 | * thresholds. | |
2216 | * @sched_scan_start: Tell the driver to start a scheduled scan. | |
2217 | * @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This | |
2218 | * call must stop the scheduled scan and be ready for starting a new one | |
2219 | * before it returns, i.e. @sched_scan_start may be called immediately | |
2220 | * after that again and should not fail in that case. The driver should | |
2221 | * not call cfg80211_sched_scan_stopped() for a requested stop (when this | |
2222 | * method returns 0.) | |
2223 | * | |
2224 | * @mgmt_frame_register: Notify driver that a management frame type was | |
2225 | * registered. Note that this callback may not sleep, and cannot run | |
2226 | * concurrently with itself. | |
2227 | * | |
2228 | * @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device. | |
2229 | * Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may | |
2230 | * reject TX/RX mask combinations they cannot support by returning -EINVAL | |
2231 | * (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX). | |
2232 | * | |
2233 | * @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant). | |
2234 | * | |
2235 | * @set_ringparam: Set tx and rx ring sizes. | |

2241 | * | |
2242 | * @probe_client: probe an associated client, must return a cookie that it | |
2243 | * later passes to cfg80211_probe_status(). | |
2244 | * | |
2245 | * @set_noack_map: Set the NoAck Map for the TIDs. | |
2246 | * | |
2247 | * @get_et_sset_count: Ethtool API to get string-set count. | |

2252 | * | |
2253 | * @get_et_strings: Ethtool API to get a set of strings to describe stats | |
2254 | * and perhaps other supported types of ethtool data-sets. | |
2255 | * See @ethtool_ops.get_strings | |
2256 | * | |
2257 | * @get_channel: Get the current operating channel for the virtual interface. | |
2258 | * For monitor interfaces, it should return %NULL unless there's a single | |
2259 | * current monitoring channel. | |
2260 | * | |
2261 | * @start_p2p_device: Start the given P2P device. | |
2262 | * @stop_p2p_device: Stop the given P2P device. | |

2265 | * Parameters include ACL policy, an array of MAC address of stations | |
2266 | * and the number of MAC addresses. If there is already a list in driver | |
2267 | * this new list replaces the existing one. Driver has to clear its ACL | |
2268 | * when number of MAC addresses entries is passed as 0. Drivers which | |
2269 | * advertise the support for MAC based ACL have to implement this callback. | |
2270 | * | |
2271 | * @start_radar_detection: Start radar detection in the driver. | |
2272 | * | |
2273 | * @update_ft_ies: Provide updated Fast BSS Transition information to the | |

2276 | * | |
2277 | * @crit_proto_start: Indicates a critical protocol needs more link reliability | |
2278 | * for a given duration (milliseconds). The protocol is provided so the | |
2279 | * driver can take the most appropriate actions. | |
2280 | * @crit_proto_stop: Indicates critical protocol no longer needs increased link | |
2281 | * reliability. This operation can not fail. | |
2282 | * @set_coalesce: Set coalesce parameters. | |
2283 | * | |
2284 | * @channel_switch: initiate channel-switch procedure (with CSA) | |
