     43  * DOC: Frame transmission/registration support
     44  *
     45  * Frame transmission and registration support exists to allow userspace
     46  * management entities such as wpa_supplicant react to management frames
     47  * that are not being handled by the kernel. This includes, for example,
     48  * certain classes of action frames that cannot be handled in the kernel
     49  * for various reasons.
     50  *
     51  * Frame registration is done on a per-interface basis and registrations
     52  * cannot be removed other than by closing the socket. It is possible to
     53  * specify a registration filter to register, for example, only for a
     54  * certain type of action frame. In particular with action frames, those
     55  * that userspace registers for will not be returned as unhandled by the
     56  * driver, so that the registered application has to take responsibility
     57  * for doing that.
     58  *
     59  * The type of frame that can be registered for is also dependent on the
     60  * driver and interface type. The frame types are advertised in wiphy
     61  * attributes so applications know what to expect.
     62  *
     63  * NOTE: When an interface changes type while registrations are active,
     64  *       these registrations are ignored until the interface type is
     65  *       changed again. This means that changing the interface type can
     66  *       lead to a situation that couldn't otherwise be produced, but
     67  *       any such registrations will be dormant in the sense that they
     68  *       will not be serviced, i.e. they will not receive any frames.
     69  *
     70  * Frame transmission allows userspace to send for example the required
     71  * responses to action frames. It is subject to some sanity checking,
     72  * but many frames can be transmitted. When a frame was transmitted, its
     73  * status is indicated to the sending socket.
     74  *
     75  * For more technical details, see the corresponding command descriptions
     76  * below.

     80  * DOC: Virtual interface / concurrency capabilities
     81  *
     82  * Some devices are able to operate with virtual MACs, they can have
     83  * more than one virtual interface. The capability handling for this
     84  * is a bit complex though, as there may be a number of restrictions
     85  * on the types of concurrency that are supported.
     86  *
     87  * To start with, each device supports the interface types listed in
     88  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
     89  * types there no concurrency is implied.
     90  *
     91  * Once concurrency is desired, more attributes must be observed:
     92  * To start with, since some interface types are purely managed in
     93  * software, like the AP-VLAN type in mac80211 for example, there's
     94  * an additional list of these, they can be added at any time and
     95  * are only restricted by some semantic restrictions (e.g. AP-VLAN
     96  * cannot be added without a corresponding AP interface). This list
     97  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
     98  *
     99  * Further, the list of supported combinations is exported. This is
    100  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
    101  * it exports a list of "groups", and at any point in time the
    102  * interfaces that are currently active must fall into any one of
    103  * the advertised groups. Within each group, there are restrictions
    104  * on the number of interfaces of different types that are supported
    105  * and also the number of different channels, along with potentially
    106  * some other restrictions. See &enum nl80211_if_combination_attrs.
    107  *
    108  * All together, these attributes define the concurrency of virtual
    109  * interfaces that a given device supports.

    266  *	results available.
    267  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
    268  *	stopped.  The driver may issue this event at any time during a
    269  *	scheduled scan.  One reason for stopping the scan is if the hardware
    270  *	does not support starting an association or a normal scan while running
    271  *	a scheduled scan.  This event is also sent when the
    272  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface

    288  * 	that caused the change such as who initiated the regulatory request
    289  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx

    296  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
    297  * 	has been found while world roaming thus enabling active scan or
    298  * 	any mode of operation that initiates TX (beacons) on a channel
    299  * 	where we would not have been able to do either before. As an example
    300  * 	if you are world roaming (regulatory domain set to world or if your
    301  * 	driver is using a custom world roaming regulatory domain) and while
    302  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
    303  * 	on a DFS channel) you will now be able to actively scan for that AP
    304  * 	or use AP mode on your card on that same channel. Note that this will
    305  * 	never be used for channels 1-11 on the 2 GHz band as they are always
    306  * 	enabled world wide. This beacon hint is only sent if your device had
    307  * 	either disabled active scanning or beaconing on a channel. We send to
    308  * 	userspace the wiphy on which we removed a restriction from
    309  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
    310  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
    311  * 	the beacon hint was processed.
    312  *
    313  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
    314  *	This command is used both as a command (request to authenticate) and
    315  *	as an event on the "mlme" multicast group indicating completion of the
    316  *	authentication process.
    317  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
    318  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
    319  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
    320  *	the SSID (mainly for association, but is included in authentication
    321  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
    322  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
    323  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
    324  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
    325  *	to be added to the frame.
    326  *	When used as an event, this reports reception of an Authentication
    327  *	frame in station and IBSS modes when the local MLME processed the
    328  *	frame, i.e., it was for the local STA and was received in correct
    329  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
    330  *	MLME SAP interface (kernel providing MLME, userspace SME). The
    331  *	included %NL80211_ATTR_FRAME attribute contains the management frame
    332  *	(including both the header and frame body, but not FCS). This event is
    333  *	also used to indicate if the authentication attempt timed out. In that
    334  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
    335  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
    336  *	pending authentication timed out).
    337  * @NL80211_CMD_ASSOCIATE: association request and notification; like
    338  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
    339  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
    340  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
    341  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
    342  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
    343  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
    344  *	primitives).
    345  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
    346  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
    347  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
    348  *
    349  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
    350  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
    351  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
    352  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
    353  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
    354  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
    355  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
    356  *
    357  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
    358  *	FREQ attribute (for the initial frequency if no peer can be found)
    359  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
    360  *	should be fixed rather than automatically determined. Can only be
    361  *	executed on a network interface that is UP, and fixed BSSID/FREQ
    362  *	may be rejected. Another optional parameter is the beacon interval,
    363  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
    364  *	given defaults to 100 TU (102.4ms).
    365  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
    366  *	determined by the network interface.
    367  *
    368  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
    369  *	to identify the device, and the TESTDATA blob attribute to pass through
    370  *	to the driver.
    371  *
    372  * @NL80211_CMD_CONNECT: connection request and notification; this command
    373  *	requests to connect to a specified network but without separating
    374  *	auth and assoc steps. For this, you need to specify the SSID in a
    375  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
    376  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
    377  *	%NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
    378  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
    379  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
    380  *	Background scan period can optionally be
    381  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
    382  *	if not specified default background scan configuration
    383  *	in driver is used and if period value is 0, bg scan will be disabled.
    384  *	This attribute is ignored if driver does not support roam scan.
    385  *	It is also sent as an event, with the BSSID and response IEs when the
    386  *	connection is established or failed to be established. This can be
    387  *	determined by the STATUS_CODE attribute.
    388  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
    389  *	sent as an event when the card/driver roamed by itself.
    390  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
    391  *	userspace that a connection was dropped by the AP or due to other
    392  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
    393  *	%NL80211_ATTR_REASON_CODE attributes are used.
    394  *
    395  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
    396  *	associated with this wiphy must be down and will follow.
    397  *
    398  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
    399  *	channel for the specified amount of time. This can be used to do
    400  *	off-channel operations like transmit a Public Action frame and wait for
    401  *	a response while being associated to an AP on another channel.
    402  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
    403  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
    404  *	frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
    405  *	optionally used to specify additional channel parameters.
    406  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
    407  *	to remain on the channel. This command is also used as an event to
    408  *	notify when the requested duration starts (it may take a while for the
    409  *	driver to schedule this time due to other concurrent needs for the
    410  *	radio).
    411  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
    412  *	that will be included with any events pertaining to this request;
    413  *	the cookie is also used to cancel the request.
    414  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
    415  *	pending remain-on-channel duration if the desired operation has been
    416  *	completed prior to expiration of the originally requested duration.
    417  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
    418  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
    419  *	uniquely identify the request.
    420  *	This command is also used as an event to notify when a requested
    421  *	remain-on-channel duration has expired.
    422  *
    423  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
    424  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
    425  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
    426  *
    427  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
    428  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
    429  *	requires an interface index, a frame type attribute (optional for
    430  *	backward compatibility reasons, if not given assumes action frames)
    431  *	and a match attribute containing the first few bytes of the frame
    432  *	that should match, e.g. a single byte for only a category match or
    433  *	four bytes for vendor frames including the OUI. The registration
    434  *	cannot be dropped, but is removed automatically when the netlink
    435  *	socket is closed. Multiple registrations can be made.
    436  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
    437  *	backward compatibility
    438  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
    439  *	command is used both as a request to transmit a management frame and
    440  *	as an event indicating reception of a frame that was not processed in
    441  *	kernel code, but is for us (i.e., which may need to be processed in a
    442  *	user space application). %NL80211_ATTR_FRAME is used to specify the
    443  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
    444  *	optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
    445  *	which channel the frame is to be transmitted or was received. If this
    446  *	channel is not the current channel (remain-on-channel or the
    447  *	operational channel) the device will switch to the given channel and
    448  *	transmit the frame, optionally waiting for a response for the time
    449  *	specified using %NL80211_ATTR_DURATION. When called, this operation
    450  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
    451  *	TX status event pertaining to the TX request.
    452  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
    453  *	management frames at CCK rate or not in 2GHz band.
    454  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
    455  *	command may be used with the corresponding cookie to cancel the wait
    456  *	time if it is known that it is no longer necessary.
    457  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
    458  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
    459  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
    460  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
    461  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
    462  *	the frame.
    463  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
    464  *	backward compatibility.
    465  *
    466  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
    467  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
    468  *
    469  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
    470  *	is used to configure connection quality monitoring notification trigger
    471  *	levels.
    472  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
    473  *	command is used as an event to indicate the that a trigger level was
    474  *	reached.
    475  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
    476  *	and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
    477  *	by %NL80211_ATTR_IFINDEX) shall operate on.
    478  *	In case multiple channels are supported by the device, the mechanism
    479  *	with which it switches channels is implementation-defined.
    480  *	When a monitor interface is given, it can only switch channel while
    481  *	no other interfaces are operating to avoid disturbing the operation
    482  *	of any other interfaces, and other interfaces will again take
    483  *	precedence when they are used.
    484  *
    485  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
    486  *
    487  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
    488  *	mesh config parameters may be given.
    489  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
    490  *	network is determined by the network interface.
    491  *
    492  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
    493  *	notification. This event is used to indicate that an unprotected
    494  *	deauthentication frame was dropped when MFP is in use.
    495  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
    496  *	notification. This event is used to indicate that an unprotected
    497  *	disassociation frame was dropped when MFP is in use.
    498  *
    499  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
    500  *      beacon or probe response from a compatible mesh peer.  This is only
    501  *      sent while no station information (sta_info) exists for the new peer
    502  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set.  On
    503  *      reception of this notification, userspace may decide to create a new
    504  *      station (@NL80211_CMD_NEW_STATION).  To stop this notification from
    505  *      reoccurring, the userspace authentication daemon may want to create the
    506  *      new station with the AUTHENTICATED flag unset and maybe change it later
    507  *      depending on the authentication result.
    508  *
    509  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
    510  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
    511  *	Since wireless is more complex than wired ethernet, it supports
    512  *	various triggers. These triggers can be configured through this
    513  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
    514  *	more background information, see
    515  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
    516  *
    517  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
    518  *	the necessary information for supporting GTK rekey offload. This
    519  *	feature is typically used during WoWLAN. The configuration data
    520  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
    521  *	contains the data in sub-attributes). After rekeying happened,
    522  *	this command may also be sent by the driver as an MLME event to
    523  *	inform userspace of the new replay counter.
    524  *
    525  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
    526  *	of PMKSA caching dandidates.
    527  *
    528  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
    529  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
    530  *
    531  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
    532  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
    533  *	implement sending deauth to stations that send unexpected class 3
    534  *	frames. Also used as the event sent by the kernel when such a frame
    535  *	is received.
    536  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
    537  *	other attributes like the interface index are present.
    538  *	If used as the command it must have an interface index and you can
    539  *	only unsubscribe from the event by closing the socket. Subscription
    540  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
    541  *
    542  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
    543  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
    544  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
    545  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
    546  *
    547  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
    548  *	by sending a null data frame to it and reporting when the frame is
    549  *	acknowleged. This is used to allow timing out inactive clients. Uses
    550  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
    551  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
    552  *	up the event with the request. The event includes the same data and
    553  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
    554  *
    555  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
    556  *	other BSSes when any interfaces are in AP mode. This helps implement
    557  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
    558  *	messages. Note that per PHY only one application may register.
    559  *
    560  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
    561  *      No Acknowledgement Policy should be applied.
    562  *
    563  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
    564  *	independently of the userspace SME, send this event indicating
    565  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ with

   1120  *	For a match to succeed, the BSS must match all attributes of a
   1121  *	set.  Since not every hardware supports matching all types of
   1122  *	attributes, there is no guarantee that the reported BSSs are
   1123  *	fully complying with the match sets and userspace needs to be
   1124  *	able to ignore them by itself.
   1125  *	Thus, the implementation is somewhat hardware-dependent, but
   1126  *	this is only an optimization and the userspace application
   1127  *	needs to handle all the non-filtered results anyway.
   1128  *	If the match attributes don't make sense when combined with
   1129  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
   1130  *	is included in the probe request, but the match attributes
   1131  *	will never let it go through), -EINVAL may be returned.
