53  * DOC: Station handling
54  *
55  * Stations are added per interface, but a special case exists with VLAN
56  * interfaces. When a station is bound to an AP interface, it may be moved
57  * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
58  * The station is still assumed to belong to the AP interface it was added
59  * to.
60  *
61  * Station handling varies per interface type and depending on the driver's
62  * capabilities.
63  *
64  * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
65  * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
66  *  - a setup station entry is added, not yet authorized, without any rate
67  *    or capability information, this just exists to avoid race conditions
68  *  - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
69  *    to add rate and capability information to the station and at the same
70  *    time mark it authorized.
71  *  - %NL80211_TDLS_ENABLE_LINK is then used
72  *  - after this, the only valid operation is to remove it by tearing down
73  *    the TDLS link (%NL80211_TDLS_DISABLE_LINK)
74  *

78 /**
79  * DOC: Frame transmission/registration support
80  *
81  * Frame transmission and registration support exists to allow userspace
82  * management entities such as wpa_supplicant react to management frames
83  * that are not being handled by the kernel. This includes, for example,
84  * certain classes of action frames that cannot be handled in the kernel
85  * for various reasons.
86  *
87  * Frame registration is done on a per-interface basis and registrations
88  * cannot be removed other than by closing the socket. It is possible to
89  * specify a registration filter to register, for example, only for a
90  * certain type of action frame. In particular with action frames, those
91  * that userspace registers for will not be returned as unhandled by the
92  * driver, so that the registered application has to take responsibility
93  * for doing that.
94  *
95  * The type of frame that can be registered for is also dependent on the
96  * driver and interface type. The frame types are advertised in wiphy
97  * attributes so applications know what to expect.
98  *
99  * NOTE: When an interface changes type while registrations are active,
100  *       these registrations are ignored until the interface type is
101  *       changed again. This means that changing the interface type can
102  *       lead to a situation that couldn't otherwise be produced, but
103  *       any such registrations will be dormant in the sense that they
104  *       will not be serviced, i.e. they will not receive any frames.
105  *
106  * Frame transmission allows userspace to send for example the required
107  * responses to action frames. It is subject to some sanity checking,
108  * but many frames can be transmitted. When a frame was transmitted, its
109  * status is indicated to the sending socket.
110  *
111  * For more technical details, see the corresponding command descriptions
112  * below.

115 /**
116  * DOC: Virtual interface / concurrency capabilities
117  *
118  * Some devices are able to operate with virtual MACs, they can have
119  * more than one virtual interface. The capability handling for this
120  * is a bit complex though, as there may be a number of restrictions
121  * on the types of concurrency that are supported.
122  *
123  * To start with, each device supports the interface types listed in
124  * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
125  * types there no concurrency is implied.
126  *
127  * Once concurrency is desired, more attributes must be observed:
128  * To start with, since some interface types are purely managed in
129  * software, like the AP-VLAN type in mac80211 for example, there's
130  * an additional list of these, they can be added at any time and
131  * are only restricted by some semantic restrictions (e.g. AP-VLAN
132  * cannot be added without a corresponding AP interface). This list
133  * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
134  *
135  * Further, the list of supported combinations is exported. This is
136  * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
137  * it exports a list of "groups", and at any point in time the
138  * interfaces that are currently active must fall into any one of
139  * the advertised groups. Within each group, there are restrictions
140  * on the number of interfaces of different types that are supported
141  * and also the number of different channels, along with potentially
142  * some other restrictions. See &enum nl80211_if_combination_attrs.
143  *
144  * All together, these attributes define the concurrency of virtual
145  * interfaces that a given device supports.

149  * DOC: packet coalesce support
150  *
151  * In most cases, host that receives IPv4 and IPv6 multicast/broadcast
152  * packets does not do anything with these packets. Therefore the
153  * reception of these unwanted packets causes unnecessary processing
154  * and power consumption.
155  *
156  * Packet coalesce feature helps to reduce number of received interrupts
157  * to host by buffering these packets in firmware/hardware for some
158  * predefined time. Received interrupt will be generated when one of the
159  * following events occur.
160  * a) Expiration of hardware timer whose expiration time is set to maximum
161  * coalescing delay of matching coalesce rule.
162  * b) Coalescing buffer in hardware reaches it's limit.
163  * c) Packet doesn't match any of the configured coalesce rules.
164  *
165  * User needs to configure following parameters for creating a coalesce
166  * rule.
167  * a) Maximum coalescing delay
168  * b) List of packet patterns which needs to be matched
169  * c) Condition for coalescence. pattern 'match' or 'no match'
170  * Multiple such rules can be created.

275  *	regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
276  *	has a private regulatory domain, it will be returned. Otherwise, the
277  *	global regdomain will be returned.
278  *	A device will have a private regulatory domain if it uses the
279  *	regulatory_hint() API. Even when a private regdomain is used the channel
280  *	information will still be mended according to further hints from

282  *	is now available which will returns the global regdomain as well as
283  *	all private regdomains of present wiphys (for those that have it).
284  *	If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
285  *	its private regdomain is the only valid one for it. The regulatory
286  *	core is not used to help with compliance in this case.
287  * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
288  *	after being queried by the kernel. CRDA replies by sending a regulatory
289  *	domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
290  *	current alpha2 if it found a match. It also provides
291  * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each
292  * 	regulatory rule is a nested set of attributes  given by
293  * 	%NL80211_ATTR_REG_RULE_FREQ_[START|END] and
294  * 	%NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
295  * 	%NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
296  * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
297  * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
298  * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
299  * 	store this as a valid request and then query userspace for it.
300  *
301  * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
302  *	interface identified by %NL80211_ATTR_IFINDEX
303  *
304  * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
305  *      interface identified by %NL80211_ATTR_IFINDEX
306  *
307  * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
308  *	interface is identified with %NL80211_ATTR_IFINDEX and the management
309  *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
310  *	added to the end of the specified management frame is specified with
311  *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
312  *	added to all specified management frames generated by
313  *	kernel/firmware/driver.
314  *	Note: This command has been removed and it is only reserved at this
315  *	point to avoid re-using existing command number. The functionality this
316  *	command was planned for has been provided with cleaner design with the
317  *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
318  *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
319  *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
320  *
321  * @NL80211_CMD_GET_SCAN: get scan results
322  * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
323  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
324  *	probe requests at CCK rate or not.
325  * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
326  *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
327  * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
328  *	partial scan results may be available
329  *
330  * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
331  *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
332  *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
333  *	are passed, they are used in the probe requests.  For
334  *	broadcast, a broadcast SSID must be passed (ie. an empty
335  *	string).  If no SSID is passed, no probe requests are sent and
336  *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
337  *	if passed, define which channels should be scanned; if not
338  *	passed, all channels allowed for the current regulatory domain
339  *	are used.  Extra IEs can also be passed from the userspace by
340  *	using the %NL80211_ATTR_IE attribute.  The first cycle of the
341  *	scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
342  *	is supplied.
343  * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
344  *	scheduled scan is not running. The caller may assume that as soon
345  *	as the call returns, it is safe to start a new scheduled scan again.
346  * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
347  *	results available.
348  * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
349  *	stopped.  The driver may issue this event at any time during a
350  *	scheduled scan.  One reason for stopping the scan is if the hardware
351  *	does not support starting an association or a normal scan while running
352  *	a scheduled scan.  This event is also sent when the
353  *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
354  *	is brought down while a scheduled scan was running.
355  *
356  * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
357  *      or noise level
358  * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
359  *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
360  *
361  * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
362  *	(for the BSSID) and %NL80211_ATTR_PMKID.
363  * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
364  *	(for the BSSID) and %NL80211_ATTR_PMKID.
365  * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
366  *
367  * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
368  * 	has been changed and provides details of the request information
369  * 	that caused the change such as who initiated the regulatory request
370  * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
371  * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
372  * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
373  * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
374  * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
375  * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
376  * 	to (%NL80211_ATTR_REG_ALPHA2).
377  * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
378  * 	has been found while world roaming thus enabling active scan or
379  * 	any mode of operation that initiates TX (beacons) on a channel
380  * 	where we would not have been able to do either before. As an example
381  * 	if you are world roaming (regulatory domain set to world or if your
382  * 	driver is using a custom world roaming regulatory domain) and while
383  * 	doing a passive scan on the 5 GHz band you find an AP there (if not
384  * 	on a DFS channel) you will now be able to actively scan for that AP
385  * 	or use AP mode on your card on that same channel. Note that this will
386  * 	never be used for channels 1-11 on the 2 GHz band as they are always
387  * 	enabled world wide. This beacon hint is only sent if your device had
388  * 	either disabled active scanning or beaconing on a channel. We send to
389  * 	userspace the wiphy on which we removed a restriction from
390  * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
391  * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
392  * 	the beacon hint was processed.
393  *
394  * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
395  *	This command is used both as a command (request to authenticate) and
396  *	as an event on the "mlme" multicast group indicating completion of the
397  *	authentication process.
398  *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
399  *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
400  *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
401  *	the SSID (mainly for association, but is included in authentication
402  *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
403  *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
404  *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
405  *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
406  *	to be added to the frame.
407  *	When used as an event, this reports reception of an Authentication
408  *	frame in station and IBSS modes when the local MLME processed the
409  *	frame, i.e., it was for the local STA and was received in correct
410  *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
411  *	MLME SAP interface (kernel providing MLME, userspace SME). The
412  *	included %NL80211_ATTR_FRAME attribute contains the management frame
413  *	(including both the header and frame body, but not FCS). This event is
414  *	also used to indicate if the authentication attempt timed out. In that
415  *	case the %NL80211_ATTR_FRAME attribute is replaced with a
416  *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
417  *	pending authentication timed out).
418  * @NL80211_CMD_ASSOCIATE: association request and notification; like
419  *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
420  *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
421  *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
422  * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
423  *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
424  *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
425  *	primitives).
426  * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
427  *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
428  *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
429  *
430  * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
431  *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
432  *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
433  *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
434  *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
435  *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
436  *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
437  *
438  * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
439  *	FREQ attribute (for the initial frequency if no peer can be found)
440  *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
441  *	should be fixed rather than automatically determined. Can only be
442  *	executed on a network interface that is UP, and fixed BSSID/FREQ
443  *	may be rejected. Another optional parameter is the beacon interval,
444  *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
445  *	given defaults to 100 TU (102.4ms).
446  * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
447  *	determined by the network interface.
448  *
449  * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
450  *	to identify the device, and the TESTDATA blob attribute to pass through
451  *	to the driver.
452  *
453  * @NL80211_CMD_CONNECT: connection request and notification; this command
454  *	requests to connect to a specified network but without separating
455  *	auth and assoc steps. For this, you need to specify the SSID in a
456  *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
457  *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_USE_MFP,
458  *	%NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
459  *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
460  *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
461  *	%NL80211_ATTR_WIPHY_FREQ_HINT.
462  *	If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
463  *	restrictions on BSS selection, i.e., they effectively prevent roaming
464  *	within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
465  *	can be included to provide a recommendation of the initial BSS while
466  *	allowing the driver to roam to other BSSes within the ESS and also to
467  *	ignore this recommendation if the indicated BSS is not ideal. Only one
468  *	set of BSSID,frequency parameters is used (i.e., either the enforcing
469  *	%NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
470  *	%NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
471  *	Background scan period can optionally be
472  *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
473  *	if not specified default background scan configuration
474  *	in driver is used and if period value is 0, bg scan will be disabled.
475  *	This attribute is ignored if driver does not support roam scan.
476  *	It is also sent as an event, with the BSSID and response IEs when the
477  *	connection is established or failed to be established. This can be
478  *	determined by the STATUS_CODE attribute.
479  * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
480  *	sent as an event when the card/driver roamed by itself.
481  * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
482  *	userspace that a connection was dropped by the AP or due to other
483  *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
484  *	%NL80211_ATTR_REASON_CODE attributes are used.
485  *
486  * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
487  *	associated with this wiphy must be down and will follow.
488  *
489  * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
490  *	channel for the specified amount of time. This can be used to do
491  *	off-channel operations like transmit a Public Action frame and wait for
492  *	a response while being associated to an AP on another channel.
493  *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
494  *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
495  *	frequency for the operation.
496  *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
497  *	to remain on the channel. This command is also used as an event to
498  *	notify when the requested duration starts (it may take a while for the
499  *	driver to schedule this time due to other concurrent needs for the
500  *	radio).
501  *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
502  *	that will be included with any events pertaining to this request;
503  *	the cookie is also used to cancel the request.
504  * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
505  *	pending remain-on-channel duration if the desired operation has been
506  *	completed prior to expiration of the originally requested duration.
507  *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
508  *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
509  *	uniquely identify the request.
510  *	This command is also used as an event to notify when a requested
511  *	remain-on-channel duration has expired.
512  *
513  * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
514  *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
515  *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
516  *
517  * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
518  *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
519  *	requires an interface index, a frame type attribute (optional for
520  *	backward compatibility reasons, if not given assumes action frames)
521  *	and a match attribute containing the first few bytes of the frame
522  *	that should match, e.g. a single byte for only a category match or
523  *	four bytes for vendor frames including the OUI. The registration
524  *	cannot be dropped, but is removed automatically when the netlink
525  *	socket is closed. Multiple registrations can be made.
526  * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
527  *	backward compatibility
528  * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
529  *	command is used both as a request to transmit a management frame and
530  *	as an event indicating reception of a frame that was not processed in
531  *	kernel code, but is for us (i.e., which may need to be processed in a
532  *	user space application). %NL80211_ATTR_FRAME is used to specify the
533  *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ is used
534  *	to indicate on which channel the frame is to be transmitted or was
535  *	received. If this channel is not the current channel (remain-on-channel
536  *	or the operational channel) the device will switch to the given channel
537  *	and transmit the frame, optionally waiting for a response for the time
538  *	specified using %NL80211_ATTR_DURATION. When called, this operation
539  *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
540  *	TX status event pertaining to the TX request.
541  *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
542  *	management frames at CCK rate or not in 2GHz band.
543  *	%NL80211_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
544  *	counters which will be updated to the current value. This attribute
545  *	is used during CSA period.
546  * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
547  *	command may be used with the corresponding cookie to cancel the wait
548  *	time if it is known that it is no longer necessary.
549  * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
550  * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
551  *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
552  *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
553  *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
554  *	the frame.
555  * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
556  *	backward compatibility.
557  *
558  * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
559  * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
560  *
561  * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
562  *	is used to configure connection quality monitoring notification trigger
563  *	levels.
564  * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
565  *	command is used as an event to indicate the that a trigger level was
566  *	reached.
567  * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
568  *	and the attributes determining channel width) the given interface
569  *	(identifed by %NL80211_ATTR_IFINDEX) shall operate on.
570  *	In case multiple channels are supported by the device, the mechanism
571  *	with which it switches channels is implementation-defined.
572  *	When a monitor interface is given, it can only switch channel while
573  *	no other interfaces are operating to avoid disturbing the operation
574  *	of any other interfaces, and other interfaces will again take
575  *	precedence when they are used.
576  *
577  * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
578  *
579  * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
580  *	mesh config parameters may be given.
581  * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
582  *	network is determined by the network interface.
583  *
584  * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
585  *	notification. This event is used to indicate that an unprotected
586  *	deauthentication frame was dropped when MFP is in use.
587  * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
588  *	notification. This event is used to indicate that an unprotected
589  *	disassociation frame was dropped when MFP is in use.
590  *
591  * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
592  *      beacon or probe response from a compatible mesh peer.  This is only
593  *      sent while no station information (sta_info) exists for the new peer
594  *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH,
595  *      @NL80211_MESH_SETUP_USERSPACE_AMPE, or
596  *      @NL80211_MESH_SETUP_USERSPACE_MPM is set.  On reception of this
597  *      notification, userspace may decide to create a new station
598  *      (@NL80211_CMD_NEW_STATION).  To stop this notification from
599  *      reoccurring, the userspace authentication daemon may want to create the
600  *      new station with the AUTHENTICATED flag unset and maybe change it later
601  *      depending on the authentication result.
602  *
603  * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
604  * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
605  *	Since wireless is more complex than wired ethernet, it supports
606  *	various triggers. These triggers can be configured through this
607  *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
608  *	more background information, see
609  *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
610  *	The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
611  *	from the driver reporting the wakeup reason. In this case, the
612  *	@NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
613  *	for the wakeup, if it was caused by wireless. If it is not present
614  *	in the wakeup notification, the wireless device didn't cause the
615  *	wakeup but reports that it was woken up.
616  *
617  * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
618  *	the necessary information for supporting GTK rekey offload. This
619  *	feature is typically used during WoWLAN. The configuration data
620  *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
621  *	contains the data in sub-attributes). After rekeying happened,
622  *	this command may also be sent by the driver as an MLME event to
623  *	inform userspace of the new replay counter.
624  *
625  * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
626  *	of PMKSA caching dandidates.
627  *
628  * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
629  *	In addition, this can be used as an event to request userspace to take
630  *	actions on TDLS links (set up a new link or tear down an existing one).
631  *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
632  *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
633  *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
634  *	%NL80211_TDLS_TEARDOWN).
635  * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
636  *	%NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
637  *	sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
638  *	802.11 management frames, while TDLS action codes (802.11-2012
639  *	8.5.13.1) will be encapsulated and sent as data frames. The currently
640  *	supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
641  *	and the currently supported TDLS actions codes are given in
642  *	&enum ieee80211_tdls_actioncode.
643  *
644  * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
645  *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
646  *	implement sending deauth to stations that send unexpected class 3
647  *	frames. Also used as the event sent by the kernel when such a frame
648  *	is received.
649  *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
650  *	other attributes like the interface index are present.
651  *	If used as the command it must have an interface index and you can
652  *	only unsubscribe from the event by closing the socket. Subscription
653  *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
654  *
655  * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
656  *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
657  *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
658  *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
659  *
660  * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
661  *	by sending a null data frame to it and reporting when the frame is
662  *	acknowleged. This is used to allow timing out inactive clients. Uses
663  *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
664  *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
665  *	up the event with the request. The event includes the same data and
666  *	has %NL80211_ATTR_ACK set if the frame was ACKed.
667  *
668  * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
669  *	other BSSes when any interfaces are in AP mode. This helps implement
670  *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
671  *	messages. Note that per PHY only one application may register.
672  *
673  * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
674  *      No Acknowledgement Policy should be applied.
675  *
676  * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
677  *	independently of the userspace SME, send this event indicating
678  *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
679  *	attributes determining channel width.  This indication may also be
680  *	sent when a remotely-initiated switch (e.g., when a STA receives a CSA
681  *	from the remote AP) is completed;
682  *
683  * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
684  *	has been started on an interface, regardless of the initiator
685  *	(ie. whether it was requested from a remote device or
686  *	initiated on our own).  It indicates that
687  *	%NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
688  *	after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's.  The userspace may
689  *	decide to react to this indication by requesting other
690  *	interfaces to change channel as well.
691  *
692  * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
693  *	its %NL80211_ATTR_WDEV identifier. It must have been created with
694  *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
695  *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
696  *	public action frame TX.
697  * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
698  *	its %NL80211_ATTR_WDEV identifier.
699  *
700  * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
701  *	notify userspace that AP has rejected the connection request from a
702  *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
703  *	is used for this.
704  *
705  * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
706  *	for IBSS or MESH vif.
707  *
708  * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
709  *	This is to be used with the drivers advertising the support of MAC
710  *	address based access control. List of MAC addresses is passed in
711  *	%NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
712  *	%NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
713  *	is not already done. The new list will replace any existing list. Driver
714  *	will clear its ACL when the list of MAC addresses passed is empty. This
715  *	command is used in AP/P2P GO mode. Driver has to make sure to clear its
716  *	ACL list during %NL80211_CMD_STOP_AP.
717  *
718  * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
719  *	a radar is detected or the channel availability scan (CAC) has finished
720  *	or was aborted, or a radar was detected, usermode will be notified with
721  *	this event. This command is also used to notify userspace about radars
722  *	while operating on this channel.
723  *	%NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
724  *	event.
725  *
726  * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
727  *	i.e. features for the nl80211 protocol rather than device features.
728  *	Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
729  *
730  * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
731  *	Information Element to the WLAN driver
732  *
733  * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
734  *	to the supplicant. This will carry the target AP's MAC address along
735  *	with the relevant Information Elements. This event is used to report
736  *	received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
737  *
738  * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
739  *	a critical protocol that needs more reliability in the connection to
740  *	complete.
741  *
742  * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
743  *	return back to normal.
744  *
745  * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
746  * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
747  *
748  * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
749  *	the new channel information (Channel Switch Announcement - CSA)
750  *	in the beacon for some time (as defined in the
751  *	%NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
752  *	new channel. Userspace provides the new channel information (using
753  *	%NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
754  *	width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
755  *	other station that transmission must be blocked until the channel
756  *	switch is complete.
757  *
758  * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
759  *	by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
760  *	%NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
761  *	%NL80211_ATTR_VENDOR_DATA.
762  *	For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
763  *	used in the wiphy data as a nested attribute containing descriptions
764  *	(&struct nl80211_vendor_cmd_info) of the supported vendor commands.
765  *	This may also be sent as an event with the same attributes.
766  *
767  * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
768  *	The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
769  *	that attribute is not included, QoS mapping is disabled. Since this
770  *	QoS mapping is relevant for IP packets, it is only valid during an
771  *	association. This is cleared on disassociation and AP restart.
772  *
773  * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
774  *	%NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
775  *	and %NL80211_ATTR_ADMITTED_TIME parameters.
776  *	Note that the action frame handshake with the AP shall be handled by
777  *	userspace via the normal management RX/TX framework, this only sets
778  *	up the TX TS in the driver/device.
779  *	If the admitted time attribute is not added then the request just checks
780  *	if a subsequent setup could be successful, the intent is to use this to
781  *	avoid setting up a session with the AP when local restrictions would
782  *	make that impossible. However, the subsequent "real" setup may still
783  *	fail even if the check was successful.
784  * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
785  *	and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
786  *	before removing a station entry entirely, or before disassociating
787  *	or similar, cleanup will happen in the driver/device in this case.
788  *
789  * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
790  *	destination %NL80211_ATTR_MAC on the interface identified by
791  *	%NL80211_ATTR_IFINDEX.
792  *
793  * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
794  *	bandwidth of a channel must be given.
795  * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
796  *	network is determined by the network interface.
797  *
798  * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
799  *	identified by the %NL80211_ATTR_MAC parameter. A target channel is
800  *	provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
801  *	channel width/type. The target operating class is given via
802  *	%NL80211_ATTR_OPER_CLASS.
803  *	The driver is responsible for continually initiating channel-switching
804  *	operations and returning to the base channel for communication with the
805  *	AP.
806  * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
807  *	peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
808  *	when this command completes.
809  *
810  * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
811  *	as an event to indicate changes for devices with wiphy-specific regdom
812  *	management.
813  *
814  * @NL80211_CMD_MAX: highest used command number
815  * @__NL80211_CMD_AFTER_LAST: internal use

1420  *	that match any of the sets will be reported.  These are
1421  *	pass-thru filter rules.
1422  *	For a match to succeed, the BSS must match all attributes of a
1423  *	set.  Since not every hardware supports matching all types of
1424  *	attributes, there is no guarantee that the reported BSSs are
1425  *	fully complying with the match sets and userspace needs to be
1426  *	able to ignore them by itself.
1427  *	Thus, the implementation is somewhat hardware-dependent, but
1428  *	this is only an optimization and the userspace application
1429  *	needs to handle all the non-filtered results anyway.
1430  *	If the match attributes don't make sense when combined with
1431  *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
1432  *	is included in the probe request, but the match attributes

3836  * DOC: TCP connection wakeup
3837  *
3838  * Some devices can establish a TCP connection in order to be woken up by a
3839  * packet coming in from outside their network segment, or behind NAT. If
3840  * configured, the device will establish a TCP connection to the given
3841  * service, and periodically send data to that service. The first data
3842  * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
3843  * The data packets can optionally include a (little endian) sequence
3844  * number (in the TCP payload!) that is generated by the device, and, also
3845  * optionally, a token from a list of tokens. This serves as a keep-alive
3846  * with the service, and for NATed connections, etc.
3847  *
3848  * During this keep-alive period, the server doesn't send any data to the
3849  * client. When receiving data, it is compared against the wakeup pattern
3850  * (and mask) and if it matches, the host is woken up. Similarly, if the
3851  * connection breaks or cannot be established to start with, the host is
3852  * also woken up.
3853  *
3854  * Developer's note: ARP offload is required for this, otherwise TCP
3855  * response packets might not go through correctly.

4238  * @NL80211_FEATURE_CELL_BASE_REG_HINTS: This driver has been tested
4239  *	to work properly to suppport receiving regulatory hints from
4240  *	cellular base stations.
4241  * @NL80211_FEATURE_P2P_DEVICE_NEEDS_CHANNEL: (no longer available, only
4242  *	here to reserve the value for API/ABI compatibility)
4243  * @NL80211_FEATURE_SAE: This driver supports simultaneous authentication of

4271  *	Peering Management entity which may be implemented by registering for
4272  *	beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
4273  *	still generated by the driver.
4274  * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
4275  *	interface. An active monitor interface behaves like a normal monitor
4276  *	interface, but gets added to the driver. It ensures that incoming
4277  *	unicast packets directed at the configured interface address get ACKed.
4278  * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
4279  *	channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
4280  *	lifetime of a BSS.
4281  * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter
4282  *	Set IE to probe requests.
4283  * @NL80211_FEATURE_WFA_TPC_IE_IN_PROBES: This device adds a WFA TPC Report IE
4284  *	to probe requests.
4285  * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
4286  *	requests sent to it by an AP.
4287  * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
4288  *	current tx power value into the TPC Report IE in the spectrum
4289  *	management TPC Report action frame, and in the Radio Measurement Link
4290  *	Measurement Report action frame.
4291  * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
4292  *	estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
4293  *	to enable dynack.
4294  * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
4295  *	multiplexing powersave, ie. can turn off all but one chain
4296  *	even on HT connections that should be using more chains.
4297  * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
4298  *	multiplexing powersave, ie. can turn off all but one chain
4299  *	and then wake the rest up as required after, for example,
4300  *	rts/cts handshake.
4301  * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
4302  *	TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS
4303  *	command. Standard IEEE 802.11 TSPEC setup is not yet supported, it
4304  *	needs to be able to handle Block-Ack agreements and other things.
4305  * @NL80211_FEATURE_MAC_ON_CREATE: Device supports configuring
