29d70e9693SJohannes Berg * DOC: Introduction
30d70e9693SJohannes Berg *
31d70e9693SJohannes Berg * cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
32d70e9693SJohannes Berg * userspace and drivers, and offers some utility functionality associated
33d70e9693SJohannes Berg * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
34d70e9693SJohannes Berg * by all modern wireless drivers in Linux, so that they offer a consistent
35d70e9693SJohannes Berg * API through nl80211. For backward compatibility, cfg80211 also offers
36d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely.
37d70e9693SJohannes Berg *
38d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum
39d70e9693SJohannes Berg * use restrictions.

44d70e9693SJohannes Berg * DOC: Device registration
45d70e9693SJohannes Berg *
46d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device
47d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs
48d70e9693SJohannes Berg * described below.
49d70e9693SJohannes Berg *
50d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each
51d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each
52d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with
53d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's
54d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes
5505b23456SRandy Dunlap * the wireless part of the interface. Normally this struct is embedded in the
56d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating
57d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the
58d70e9693SJohannes Berg * ability to create some the wireless device isn't useful.
59d70e9693SJohannes Berg *
60d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has
61d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and
62d70e9693SJohannes Berg * structures here describe these capabilities in detail.

2577d70e9693SJohannes Berg *
2578d70e9693SJohannes Berg * The scanning process itself is fairly simple, but cfg80211 offers quite
2579d70e9693SJohannes Berg * a bit of helper functionality. To start a scan, the scan operation will
2580d70e9693SJohannes Berg * be invoked with a scan definition. This scan definition contains the
2581d70e9693SJohannes Berg * channels to scan, and the SSIDs to send probe requests for (including the
2582d70e9693SJohannes Berg * wildcard, if desired). A passive scan is indicated by having no SSIDs to
2583d70e9693SJohannes Berg * probe. Additionally, a scan request may contain extra information elements
2584d70e9693SJohannes Berg * that should be added to the probe request. The IEs are guaranteed to be
2585d70e9693SJohannes Berg * well-formed, and will not exceed the maximum length the driver advertised
2586d70e9693SJohannes Berg * in the wiphy structure.
2587d70e9693SJohannes Berg *
2588d70e9693SJohannes Berg * When scanning finds a BSS, cfg80211 needs to be notified of that, because
2589d70e9693SJohannes Berg * it is responsible for maintaining the BSS list; the driver should not
2590d70e9693SJohannes Berg * maintain a list itself. For this notification, various functions exist.
2591d70e9693SJohannes Berg *
2592d70e9693SJohannes Berg * Since drivers do not maintain a BSS list, there are also a number of
2593d70e9693SJohannes Berg * functions to search for a BSS and obtain information about it from the
2594d70e9693SJohannes Berg * BSS structure cfg80211 maintains. The BSS list is also made available
2595d70e9693SJohannes Berg * to userspace.

4329bf1ecd21SJouni Malinen * from the AP or cfg80211_connect_timeout() if no frame with status code
4330bf1ecd21SJouni Malinen * was received.
4331bf1ecd21SJouni Malinen * The driver is allowed to roam to other BSSes within the ESS when the
4332bf1ecd21SJouni Malinen * other BSS matches the connect parameters. When such roaming is initiated
4333bf1ecd21SJouni Malinen * by the driver, the driver is expected to verify that the target matches
4334bf1ecd21SJouni Malinen * the configured security parameters and to use Reassociation Request
4335bf1ecd21SJouni Malinen * frame instead of Association Request frame.
4336bf1ecd21SJouni Malinen * The connect function can also be used to request the driver to perform a
4337bf1ecd21SJouni Malinen * specific roam when connected to an ESS. In that case, the prev_bssid

4345088e8df8Svamsi krishna * subsequent BSS selection (roaming) decisions and to form the
4346088e8df8Svamsi krishna * Authentication/(Re)Association Request frames. This call does not
4347088e8df8Svamsi krishna * request an immediate disassociation or reassociation with the current
4348088e8df8Svamsi krishna * BSS, i.e., this impacts only subsequent (re)associations. The bits in
4349088e8df8Svamsi krishna * changed are defined in &enum cfg80211_connect_params_changed.

448397dc94f1SMichal Kazior * inherently tricky driver may decide to disconnect an interface later
448497dc94f1SMichal Kazior * with cfg80211_stop_iface(). This doesn't mean driver can accept
448597dc94f1SMichal Kazior * everything. It should do it's best to verify requests and reject them
448697dc94f1SMichal Kazior * as soon as possible.

4495960d01acSJohannes Berg * with the given parameters; action frame exchange has been handled by
4496960d01acSJohannes Berg * userspace so this just has to modify the TX path to take the TS into
4497960d01acSJohannes Berg * account.
4498960d01acSJohannes Berg * If the admitted time is 0 just validate the parameters to make sure
4499960d01acSJohannes Berg * the session can be created at all; it is valid to just always return
4500960d01acSJohannes Berg * success for that but that may result in inefficient behaviour (handshake
4501960d01acSJohannes Berg * with the peer followed by immediate teardown when the addition is later
4502960d01acSJohannes Berg * rejected)
