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

44 | * DOC: Device registration | |
45 | * | |
46 | * In order for a driver to use cfg80211, it must register the hardware device | |
47 | * with cfg80211. This happens through a number of hardware capability structs | |
48 | * described below. | |
49 | * | |
50 | * The fundamental structure for each device is the 'wiphy', of which each | |
51 | * instance describes a physical wireless device connected to the system. Each | |
52 | * such wiphy can have zero, one, or many virtual interfaces associated with | |
53 | * it, which need to be identified as such by pointing the network interface's | |
54 | * @ieee80211_ptr pointer to a &struct wireless_dev which further describes | |
05b23456 | 55 | * the wireless part of the interface. Normally this struct is embedded in the |
d70e9693 JB |
56 | * network interface's private data area. Drivers can optionally allow creating |
57 | * or destroying virtual interfaces on the fly, but without at least one or the | |
58 | * ability to create some the wireless device isn't useful. | |
59 | * | |
60 | * Each wiphy structure contains device capability information, and also has | |
61 | * a pointer to the various operations the driver offers. The definitions and | |
62 | * structures here describe these capabilities in detail. | |

2543 | * | |
2544 | * The scanning process itself is fairly simple, but cfg80211 offers quite | |
2545 | * a bit of helper functionality. To start a scan, the scan operation will | |
2546 | * be invoked with a scan definition. This scan definition contains the | |
2547 | * channels to scan, and the SSIDs to send probe requests for (including the | |
2548 | * wildcard, if desired). A passive scan is indicated by having no SSIDs to | |
2549 | * probe. Additionally, a scan request may contain extra information elements | |
2550 | * that should be added to the probe request. The IEs are guaranteed to be | |
2551 | * well-formed, and will not exceed the maximum length the driver advertised | |
2552 | * in the wiphy structure. | |
2553 | * | |
2554 | * When scanning finds a BSS, cfg80211 needs to be notified of that, because | |
2555 | * it is responsible for maintaining the BSS list; the driver should not | |
2556 | * maintain a list itself. For this notification, various functions exist. | |
2557 | * | |
2558 | * Since drivers do not maintain a BSS list, there are also a number of | |
2559 | * functions to search for a BSS and obtain information about it from the | |
2560 | * BSS structure cfg80211 maintains. The BSS list is also made available | |
2561 | * to userspace. | |

4300 | * The driver is allowed to roam to other BSSes within the ESS when the | |
4301 | * other BSS matches the connect parameters. When such roaming is initiated | |
4302 | * by the driver, the driver is expected to verify that the target matches | |
4303 | * the configured security parameters and to use Reassociation Request | |
4304 | * frame instead of Association Request frame. | |
4305 | * The connect function can also be used to request the driver to perform a | |
4306 | * specific roam when connected to an ESS. In that case, the prev_bssid | |
35eb8f7b | 4307 | * parameter is set to the BSSID of the currently associated BSS as an |
bf1ecd21 JM |
4308 | * indication of requesting reassociation. |
4309 | * In both the driver-initiated and new connect() call initiated roaming | |

088e8df8 | 4312 | * @update_connect_params: Update the connect parameters while connected to a |
4313 | * BSS. The updated parameters can be used by driver/firmware for | |
4314 | * subsequent BSS selection (roaming) decisions and to form the | |
4315 | * Authentication/(Re)Association Request frames. This call does not | |
4316 | * request an immediate disassociation or reassociation with the current | |
4317 | * BSS, i.e., this impacts only subsequent (re)associations. The bits in | |
4318 | * changed are defined in &enum cfg80211_connect_params_changed. | |

4354 | * channel for the specified duration to complete an off-channel | |
4355 | * operation (e.g., public action frame exchange). When the driver is | |
4356 | * ready on the requested channel, it must indicate this with an event | |
4357 | * notification by calling cfg80211_ready_on_channel(). | |
4358 | * @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation. | |

4a4b8169 AZ |
4387 | * @set_cqm_rssi_range_config: Configure two RSSI thresholds in the |
4388 | * connection quality monitor. An event is to be sent only when the | |
4389 | * signal level is found to be outside the two values. The driver should | |
4390 | * set %NL80211_EXT_FEATURE_CQM_RSSI_LIST if this method is implemented. | |
4391 | * If it is provided then there's no point providing @set_cqm_rssi_config. | |

4397 | * for starting a new one before it returns, i.e. @sched_scan_start may be | |
4398 | * called immediately after that again and should not fail in that case. | |

4430 | * this new list replaces the existing one. Driver has to clear its ACL | |
4431 | * when number of MAC addresses entries is passed as 0. Drivers which | |
4432 | * advertise the support for MAC based ACL have to implement this callback. | |

4451 | * responsible for veryfing if the switch is possible. Since this is | |
4452 | * inherently tricky driver may decide to disconnect an interface later | |
4453 | * with cfg80211_stop_iface(). This doesn't mean driver can accept | |

4464 | * with the given parameters; action frame exchange has been handled by | |
4465 | * userspace so this just has to modify the TX path to take the TS into | |
4466 | * account. | |
4467 | * If the admitted time is 0 just validate the parameters to make sure | |
4468 | * the session can be created at all; it is valid to just always return | |

4925 | * @WIPHY_FLAG_SPLIT_SCAN_6GHZ: if set to true, the scan request will be split |
4926 | * into two, first for legacy bands and second for UHB. | |
5be83de5 JB |
4927 | * @WIPHY_FLAG_NETNS_OK: if not set, do not allow changing the netns of this |
4928 | * wiphy at all | |
4929 | * @WIPHY_FLAG_PS_ON_BY_DEFAULT: if set to true, powersave will be enabled | |
4930 | * by default -- this flag will be set depending on the kernel's default | |
4931 | * on wiphy_new(), but can be changed by the driver if it has a good | |
4932 | * reason to override the default | |
9bc383de | 4933 | * @WIPHY_FLAG_4ADDR_AP: supports 4addr mode even on AP (with a single station |
33d915d9 MP |
4934 | * on a VLAN interface). This flag also serves an extra purpose of |
4935 | * supporting 4ADDR AP mode on devices which do not support AP/VLAN iftype. | |
9bc383de | 4936 | * @WIPHY_FLAG_4ADDR_STATION: supports 4addr mode even as a station |
c0692b8f JB |
4937 | * @WIPHY_FLAG_CONTROL_PORT_PROTOCOL: This device supports setting the |
4938 | * control port protocol ethertype. The device also honours the | |

4946 | * @WIPHY_FLAG_SUPPORTS_TDLS: The device supports TDLS (802.11z) operation. |
4947 | * @WIPHY_FLAG_TDLS_EXTERNAL_SETUP: The device does not handle TDLS (802.11z) | |
4948 | * link setup/discovery operations internally. Setup, discovery and | |
4949 | * teardown packets should be sent through the @NL80211_CMD_TDLS_MGMT | |
4950 | * command. When this flag is not set, @NL80211_CMD_TDLS_OPER should be | |
4951 | * used for asking the driver/firmware to perform a TDLS operation. | |
562a7480 | 4952 | * @WIPHY_FLAG_HAVE_AP_SME: device integrates AP SME |
5e760230 JB |

16ef1fe2 SW |
4961 | * @WIPHY_FLAG_HAS_CHANNEL_SWITCH: Device supports channel switch in |
4962 | * beaconing mode (AP, IBSS, Mesh, ...). | |
093a48d2 | 4963 | * @WIPHY_FLAG_SUPPORTS_EXT_KEK_KCK: The device supports bigger kek and kck keys |
7b0a0e3c JB |
4964 | * @WIPHY_FLAG_SUPPORTS_MLO: This is a temporary flag gating the MLO APIs, |
4965 | * in order to not have them reachable in normal drivers, until we have | |
4966 | * complete feature/interface combinations/etc. advertisement. No driver | |
4967 | * should set this flag for now. | |
648fba79 | 4968 | * @WIPHY_FLAG_SUPPORTS_EXT_KCK_32: The device supports 32-byte KCK keys. |
d99975c4 WG |
