32 /**
33  * DOC: Station handling
34  *
35  * Stations are added per interface, but a special case exists with VLAN
36  * interfaces. When a station is bound to an AP interface, it may be moved
37  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
38  * The station is still assumed to belong to the AP interface it was added
39  * to.
40  *
41  * Station handling varies per interface type and depending on the driver's
42  * capabilities.
43  *
44  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
45  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
46  *  - a setup station entry is added, not yet authorized, without any rate
47  *    or capability information, this just exists to avoid race conditions
48  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
49  *    to add rate and capability information to the station and at the same
50  *    time mark it authorized.
51  *  - %NL80211_TDLS_ENABLE_LINK is then used
52  *  - after this, the only valid operation is to remove it by tearing down
53  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
54  *

58 /**
59  * DOC: Frame transmission/registration support
60  *
61  * Frame transmission and registration support exists to allow userspace
62  * management entities such as wpa_supplicant react to management frames
63  * that are not being handled by the kernel. This includes, for example,
64  * certain classes of action frames that cannot be handled in the kernel
65  * for various reasons.
66  *
67  * Frame registration is done on a per-interface basis and registrations
68  * cannot be removed other than by closing the socket. It is possible to
69  * specify a registration filter to register, for example, only for a
70  * certain type of action frame. In particular with action frames, those
71  * that userspace registers for will not be returned as unhandled by the
72  * driver, so that the registered application has to take responsibility
73  * for doing that.
74  *
75  * The type of frame that can be registered for is also dependent on the
76  * driver and interface type. The frame types are advertised in wiphy
77  * attributes so applications know what to expect.
78  *
79  * NOTE: When an interface changes type while registrations are active,
80  *       these registrations are ignored until the interface type is
81  *       changed again. This means that changing the interface type can
82  *       lead to a situation that couldn't otherwise be produced, but
83  *       any such registrations will be dormant in the sense that they
84  *       will not be serviced, i.e. they will not receive any frames.
85  *
86  * Frame transmission allows userspace to send for example the required
87  * responses to action frames. It is subject to some sanity checking,
88  * but many frames can be transmitted. When a frame was transmitted, its
89  * status is indicated to the sending socket.
90  *
91  * For more technical details, see the corresponding command descriptions
92  * below.

95 /**
96  * DOC: Virtual interface / concurrency capabilities
97  *
98  * Some devices are able to operate with virtual MACs, they can have
99  * more than one virtual interface. The capability handling for this
100  * is a bit complex though, as there may be a number of restrictions
101  * on the types of concurrency that are supported.
102  *
103  * To start with, each device supports the interface types listed in
104  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
105  * types there no concurrency is implied.
106  *
107  * Once concurrency is desired, more attributes must be observed:
108  * To start with, since some interface types are purely managed in
109  * software, like the AP-VLAN type in mac80211 for example, there's
110  * an additional list of these, they can be added at any time and
111  * are only restricted by some semantic restrictions (e.g. AP-VLAN
112  * cannot be added without a corresponding AP interface). This list
113  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
114  *
115  * Further, the list of supported combinations is exported. This is
116  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
117  * it exports a list of "groups", and at any point in time the
118  * interfaces that are currently active must fall into any one of
119  * the advertised groups. Within each group, there are restrictions
120  * on the number of interfaces of different types that are supported
121  * and also the number of different channels, along with potentially
122  * some other restrictions. See &enum nl80211_if_combination_attrs.
123  *
124  * All together, these attributes define the concurrency of virtual
125  * interfaces that a given device supports.

128 /**
129  * DOC: packet coalesce support
130  *
131  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
132  * packets does not do anything with these packets. Therefore the
133  * reception of these unwanted packets causes unnecessary processing
134  * and power consumption.
135  *
136  * Packet coalesce feature helps to reduce number of received interrupts
137  * to host by buffering these packets in firmware/hardware for some
138  * predefined time. Received interrupt will be generated when one of the
139  * following events occur.
140  * a) Expiration of hardware timer whose expiration time is set to maximum
141  * coalescing delay of matching coalesce rule.
142  * b) Coalescing buffer in hardware reaches it's limit.
143  * c) Packet doesn't match any of the configured coalesce rules.
144  *
145  * User needs to configure following parameters for creating a coalesce
146  * rule.
147  * a) Maximum coalescing delay
148  * b) List of packet patterns which needs to be matched
149  * c) Condition for coalescence. pattern 'match' or 'no match'
150  * Multiple such rules can be created.

274  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
275  *	added to the end of the specified management frame is specified with
276  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
277  *	added to all specified management frames generated by
278  *	kernel/firmware/driver.
279  *	Note: This command has been removed and it is only reserved at this

285  *
286  * @NL80211_CMD_GET_SCAN: get scan results
287  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
288  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
289  *	probe requests at CCK rate or not.
290  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
291  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
292  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
293  *	partial scan results may be available
294  *
295  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
296  *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
297  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
298  *	are passed, they are used in the probe requests.  For
299  *	broadcast, a broadcast SSID must be passed (ie. an empty
300  *	string).  If no SSID is passed, no probe requests are sent and
301  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
302  *	if passed, define which channels should be scanned; if not
303  *	passed, all channels allowed for the current regulatory domain
304  *	are used.  Extra IEs can also be passed from the userspace by
305  *	using the %NL80211_ATTR_IE attribute.
306  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
307  *	if scheduled scan is not running.
308  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
309  *	results available.
310  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
311  *	stopped.  The driver may issue this event at any time during a
312  *	scheduled scan.  One reason for stopping the scan is if the hardware
313  *	does not support starting an association or a normal scan while running
314  *	a scheduled scan.  This event is also sent when the
315  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
316  *	is brought down while a scheduled scan was running.
317  *
318  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
319  *      or noise level
320  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
321  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
322  *
323  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
324  *	(for the BSSID) and %NL80211_ATTR_PMKID.
325  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
326  *	(for the BSSID) and %NL80211_ATTR_PMKID.
327  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
328  *
329  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
330  * 	has been changed and provides details of the request information
331  * 	that caused the change such as who initiated the regulatory request
332  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
333  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
334  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
335  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
336  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
337  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
338  * 	to (%NL80211_ATTR_REG_ALPHA2).
339  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
340  * 	has been found while world roaming thus enabling active scan or
341  * 	any mode of operation that initiates TX (beacons) on a channel
342  * 	where we would not have been able to do either before. As an example
343  * 	if you are world roaming (regulatory domain set to world or if your
344  * 	driver is using a custom world roaming regulatory domain) and while
345  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
346  * 	on a DFS channel) you will now be able to actively scan for that AP
347  * 	or use AP mode on your card on that same channel. Note that this will
348  * 	never be used for channels 1-11 on the 2 GHz band as they are always
349  * 	enabled world wide. This beacon hint is only sent if your device had
350  * 	either disabled active scanning or beaconing on a channel. We send to
351  * 	userspace the wiphy on which we removed a restriction from
352  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
353  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
354  * 	the beacon hint was processed.
355  *
356  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
357  *	This command is used both as a command (request to authenticate) and
358  *	as an event on the "mlme" multicast group indicating completion of the
359  *	authentication process.
360  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
361  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
362  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
363  *	the SSID (mainly for association, but is included in authentication
364  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
365  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
366  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
367  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
368  *	to be added to the frame.
369  *	When used as an event, this reports reception of an Authentication
370  *	frame in station and IBSS modes when the local MLME processed the
371  *	frame, i.e., it was for the local STA and was received in correct
372  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
373  *	MLME SAP interface (kernel providing MLME, userspace SME). The
374  *	included %NL80211_ATTR_FRAME attribute contains the management frame
375  *	(including both the header and frame body, but not FCS). This event is
376  *	also used to indicate if the authentication attempt timed out. In that
377  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
378  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
379  *	pending authentication timed out).
380  * @NL80211_CMD_ASSOCIATE: association request and notification; like
381  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
382  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
383  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
384  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
385  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
386  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
387  *	primitives).
388  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
389  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
390  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
391  *
392  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
393  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
394  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
395  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
396  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
397  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
398  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
399  *
400  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
401  *	FREQ attribute (for the initial frequency if no peer can be found)
402  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
403  *	should be fixed rather than automatically determined. Can only be
404  *	executed on a network interface that is UP, and fixed BSSID/FREQ
405  *	may be rejected. Another optional parameter is the beacon interval,
406  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
407  *	given defaults to 100 TU (102.4ms).
408  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
409  *	determined by the network interface.
410  *
411  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
412  *	to identify the device, and the TESTDATA blob attribute to pass through
413  *	to the driver.
414  *
415  * @NL80211_CMD_CONNECT: connection request and notification; this command
416  *	requests to connect to a specified network but without separating
417  *	auth and assoc steps. For this, you need to specify the SSID in a
418  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
419  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
420  *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
421  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
422  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
423  *	Background scan period can optionally be
424  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
425  *	if not specified default background scan configuration
426  *	in driver is used and if period value is 0, bg scan will be disabled.
427  *	This attribute is ignored if driver does not support roam scan.
428  *	It is also sent as an event, with the BSSID and response IEs when the
429  *	connection is established or failed to be established. This can be
430  *	determined by the STATUS_CODE attribute.
431  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
432  *	sent as an event when the card/driver roamed by itself.
433  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
434  *	userspace that a connection was dropped by the AP or due to other
435  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
436  *	%NL80211_ATTR_REASON_CODE attributes are used.
437  *
438  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
439  *	associated with this wiphy must be down and will follow.
440  *
441  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
442  *	channel for the specified amount of time. This can be used to do
443  *	off-channel operations like transmit a Public Action frame and wait for
444  *	a response while being associated to an AP on another channel.
445  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
446  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
447  *	frequency for the operation.
448  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
449  *	to remain on the channel. This command is also used as an event to
450  *	notify when the requested duration starts (it may take a while for the
451  *	driver to schedule this time due to other concurrent needs for the
452  *	radio).
453  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
454  *	that will be included with any events pertaining to this request;
455  *	the cookie is also used to cancel the request.
456  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
457  *	pending remain-on-channel duration if the desired operation has been
458  *	completed prior to expiration of the originally requested duration.
459  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
460  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
461  *	uniquely identify the request.
462  *	This command is also used as an event to notify when a requested
463  *	remain-on-channel duration has expired.
464  *
465  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
466  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
467  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
468  *
469  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
470  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
471  *	requires an interface index, a frame type attribute (optional for
472  *	backward compatibility reasons, if not given assumes action frames)
473  *	and a match attribute containing the first few bytes of the frame
474  *	that should match, e.g. a single byte for only a category match or
475  *	four bytes for vendor frames including the OUI. The registration
476  *	cannot be dropped, but is removed automatically when the netlink
477  *	socket is closed. Multiple registrations can be made.
478  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
479  *	backward compatibility
480  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
481  *	command is used both as a request to transmit a management frame and
482  *	as an event indicating reception of a frame that was not processed in
483  *	kernel code, but is for us (i.e., which may need to be processed in a
484  *	user space application). %NL80211_ATTR_FRAME is used to specify the
485  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
486  *	to indicate on which channel the frame is to be transmitted or was
487  *	received. If this channel is not the current channel (remain-on-channel
488  *	or the operational channel) the device will switch to the given channel
489  *	and transmit the frame, optionally waiting for a response for the time
490  *	specified using %NL80211_ATTR_DURATION. When called, this operation
491  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
492  *	TX status event pertaining to the TX request.
493  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
494  *	management frames at CCK rate or not in 2GHz band.
495  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
496  *	command may be used with the corresponding cookie to cancel the wait
497  *	time if it is known that it is no longer necessary.
498  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
499  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
500  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
501  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
502  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
503  *	the frame.
504  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
505  *	backward compatibility.
506  *
507  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
508  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
509  *
510  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
511  *	is used to configure connection quality monitoring notification trigger
512  *	levels.
513  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
514  *	command is used as an event to indicate the that a trigger level was
515  *	reached.
516  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
517  *	and the attributes determining channel width) the given interface
518  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
519  *	In case multiple channels are supported by the device, the mechanism
520  *	with which it switches channels is implementation-defined.
521  *	When a monitor interface is given, it can only switch channel while
522  *	no other interfaces are operating to avoid disturbing the operation
523  *	of any other interfaces, and other interfaces will again take
524  *	precedence when they are used.
525  *
526  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
527  *
528  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
529  *	mesh config parameters may be given.
530  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
531  *	network is determined by the network interface.
532  *
533  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
534  *	notification. This event is used to indicate that an unprotected
535  *	deauthentication frame was dropped when MFP is in use.
536  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
537  *	notification. This event is used to indicate that an unprotected
538  *	disassociation frame was dropped when MFP is in use.
539  *
540  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
541  *      beacon or probe response from a compatible mesh peer.  This is only
542  *      sent while no station information (sta_info) exists for the new peer
543  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
544  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
545  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
546  *      notification, userspace may decide to create a new station
547  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
548  *      reoccurring, the userspace authentication daemon may want to create the
549  *      new station with the AUTHENTICATED flag unset and maybe change it later
550  *      depending on the authentication result.
551  *
552  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
553  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
554  *	Since wireless is more complex than wired ethernet, it supports
555  *	various triggers. These triggers can be configured through this
556  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
557  *	more background information, see
558  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
559  *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
560  *	from the driver reporting the wakeup reason. In this case, the
561  *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
562  *	for the wakeup, if it was caused by wireless. If it is not present
563  *	in the wakeup notification, the wireless device didn't cause the
564  *	wakeup but reports that it was woken up.
565  *
566  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
567  *	the necessary information for supporting GTK rekey offload. This
568  *	feature is typically used during WoWLAN. The configuration data
569  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
570  *	contains the data in sub-attributes). After rekeying happened,
571  *	this command may also be sent by the driver as an MLME event to
572  *	inform userspace of the new replay counter.
573  *
574  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
575  *	of PMKSA caching dandidates.
576  *
577  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
578  *	In addition, this can be used as an event to request userspace to take
579  *	actions on TDLS links (set up a new link or tear down an existing one).
580  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
581  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
582  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
583  *	%NL80211_TDLS_TEARDOWN).
584  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
585  *
586  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
587  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
588  *	implement sending deauth to stations that send unexpected class 3
589  *	frames. Also used as the event sent by the kernel when such a frame
590  *	is received.
591  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
592  *	other attributes like the interface index are present.
593  *	If used as the command it must have an interface index and you can
594  *	only unsubscribe from the event by closing the socket. Subscription
595  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
596  *
597  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
598  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
599  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
600  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
601  *
602  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
603  *	by sending a null data frame to it and reporting when the frame is
604  *	acknowleged. This is used to allow timing out inactive clients. Uses
605  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
606  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
607  *	up the event with the request. The event includes the same data and
608  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
609  *
610  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
611  *	other BSSes when any interfaces are in AP mode. This helps implement
612  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
613  *	messages. Note that per PHY only one application may register.
614  *
615  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
616  *      No Acknowledgement Policy should be applied.
617  *
618  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
619  *	independently of the userspace SME, send this event indicating
620  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
621  *	attributes determining channel width.
622  *
623  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
624  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
625  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
626  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
627  *	public action frame TX.
628  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
629  *	its %NL80211_ATTR_WDEV identifier.
630  *
631  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
632  *	notify userspace that AP has rejected the connection request from a
633  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
634  *	is used for this.
635  *
636  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
637  *	for IBSS or MESH vif.
638  *
639  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
640  *	This is to be used with the drivers advertising the support of MAC
641  *	address based access control. List of MAC addresses is passed in
642  *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
643  *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
644  *	is not already done. The new list will replace any existing list. Driver
645  *	will clear its ACL when the list of MAC addresses passed is empty. This
646  *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
647  *	ACL list during %NL80211_CMD_STOP_AP.
648  *
649  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
650  *	a radar is detected or the channel availability scan (CAC) has finished
651  *	or was aborted, or a radar was detected, usermode will be notified with
652  *	this event. This command is also used to notify userspace about radars
653  *	while operating on this channel.
654  *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
655  *	event.
656  *
657  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
658  *	i.e. features for the nl80211 protocol rather than device features.
659  *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
660  *
661  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
662  *	Information Element to the WLAN driver
663  *
664  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
665  *	to the supplicant. This will carry the target AP's MAC address along
666  *	with the relevant Information Elements. This event is used to report
667  *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
668  *
669  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
670  *	a critical protocol that needs more reliability in the connection to
671  *	complete.
672  *
673  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
674  *	return back to normal.

680  *	the new channel information (Channel Switch Announcement - CSA)
681  *	in the beacon for some time (as defined in the
682  *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
683  *	new channel. Userspace provides the new channel information (using
684  *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
685  *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
686  *	other station that transmission must be blocked until the channel
687  *	switch is complete.

1255  *	containing attributes from &enum nl80211_meshconf_params.
1256  * @NL80211_ATTR_SUPPORT_MESH_AUTH: Currently, this means the underlying driver
1257  *	allows auth frames in a mesh to be passed to userspace for processing via
1258  *	the @NL80211_MESH_SETUP_USERSPACE_AUTH flag.
1259  * @NL80211_ATTR_STA_PLINK_STATE: The state of a mesh peer link as defined in

1269  *	triggers.
1270  *
1271  * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
1272  *	cycles, in msecs.
1273  *
1274  * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
1275  *	sets of attributes to match during scheduled scans.  Only BSSs
1276  *	that match any of the sets will be reported.  These are
1277  *	pass-thru filter rules.
1278  *	For a match to succeed, the BSS must match all attributes of a
1279  *	set.  Since not every hardware supports matching all types of
1280  *	attributes, there is no guarantee that the reported BSSs are
1281  *	fully complying with the match sets and userspace needs to be
1282  *	able to ignore them by itself.
1283  *	Thus, the implementation is somewhat hardware-dependent, but
1284  *	this is only an optimization and the userspace application
1285  *	needs to handle all the non-filtered results anyway.
1286  *	If the match attributes don't make sense when combined with
1287  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1288  *	is included in the probe request, but the match attributes

1315  *	driver (or firmware) replies to Probe Request frames.
1316  * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
1317  *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and

1334  *	for management frames transmission. In order to avoid p2p probe/action
1335  *	frames are being transmitted at CCK rate in 2GHz band, the user space
1336  *	applications use this attribute.
1337  *	This attribute is used with %NL80211_CMD_TRIGGER_SCAN and

1358  *
1359  * @NL80211_ATTR_DONT_WAIT_FOR_ACK: Used with %NL80211_CMD_FRAME, this tells
1360  *	the driver to not wait for an acknowledgement. Note that due to this,
1361  *	it will also not give a status callback nor return a cookie. This is
1362  *	mostly useful for probe responses to save airtime.

1394  *	used by the drivers which has MLME in firmware and does not have support
1395  *	to report per station tx/rx activity to free up the staion entry from

1397  *	capability to timeout the stations.
1398  *
1399  * @NL80211_ATTR_RX_SIGNAL_DBM: signal strength in dBm (as a 32-bit int);

3319  * DOC: TCP connection wakeup
3320  *
3321  * Some devices can establish a TCP connection in order to be woken up by a
3322  * packet coming in from outside their network segment, or behind NAT. If
3323  * configured, the device will establish a TCP connection to the given
3324  * service, and periodically send data to that service. The first data
3325  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3326  * The data packets can optionally include a (little endian) sequence
3327  * number (in the TCP payload!) that is generated by the device, and, also
3328  * optionally, a token from a list of tokens. This serves as a keep-alive
3329  * with the service, and for NATed connections, etc.
3330  *
3331  * During this keep-alive period, the server doesn't send any data to the
3332  * client. When receiving data, it is compared against the wakeup pattern
3333  * (and mask) and if it matches, the host is woken up. Similarly, if the
3334  * connection breaks or cannot be established to start with, the host is
3335  * also woken up.
3336  *
3337  * Developer's note: ARP offload is required for this, otherwise TCP
3338  * response packets might not go through correctly.

3718  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
3719  *	to work properly to suppport receiving regulatory hints from
3720  *	cellular base stations.
3721  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: If this is set, an active
3722  *	P2P Device (%NL80211_IFTYPE_P2P_DEVICE) requires its own channel
3723  *	in the interface combinations, even when it's only used for scan
3724  *	and remain-on-channel. This could be due to, for example, the
3725  *	remain-on-channel implementation requiring a channel context.
3726  * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of
3727  *	equals (SAE) with user space SME (NL80211_CMD_AUTHENTICATE) in station
3728  *	mode
3729  * @NL80211_FEATURE_LOW_PRIORITY_SCAN: This driver supports low priority scan

3734  *	OBSS scans and generate 20/40 BSS coex reports. This flag is used only
3735  *	for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.

3739  *	powersave

3741  *	transitions for AP clients. Without this flag (and if the driver
3742  *	doesn't have the AP SME in the device) the driver supports adding
3743  *	stations only when they're associated and adds them in associated
3744  *	state (to later be transitioned into authorized), with this flag
3745  *	they should be added before even sending the authentication reply
3746  *	and then transitioned into authenticated, associated and authorized
3747  *	states using station flags.
3748  *	Note that even for drivers that support this, the default is to add

3756  *	still generated by the driver.
3757  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
3758  *	interface. An active monitor interface behaves like a normal monitor
3759  *	interface, but gets added to the driver. It ensures that incoming
3760  *	unicast packets directed at the configured interface address get ACKed.
