115
117 suspend
118 wiphy device needs to be suspended. The variable wow will be NULL
119 or contain the enabled Wake-on-Wireless triggers that are
120 configured for the device.
121 resume
123 wiphy device needs to be resumed
124 set_wakeup
126 Called when WoWLAN is enabled/disabled, use this callback to call
127 device_set_wakeup_enable to enable/disable wakeup from the device.
128 add_virtual_intf
130 create a new virtual interface with the given name, must set the
131 struct wireless_dev's iftype. Beware: You must create the new
132 netdev in the wiphy's network namespace! Returns the struct
133 wireless_dev, or an ERR_PTR. For P2P device wdevs, the driver must
134 also set the address member in the wdev.
135 del_virtual_intf
137 remove the virtual interface
138 change_virtual_intf
140 change type/configuration of virtual interface, keep the struct
141 wireless_dev's iftype updated.
142 add_key
144 add a key with the given parameters. mac_addr will be NULL when
145 adding a group key.
146 get_key
148 get information about the key with the given parameters. mac_addr
149 will be NULL when requesting information for a group key. All
150 pointers given to the callback function need not be valid after it
151 returns. This function should return an error if it is not possible
152 to retrieve the key, -ENOENT if it doesn't exist.
153 del_key
155 remove a key given the mac_addr (NULL for a group key) and
156 key_index, return -ENOENT if the key doesn't exist.
157 set_default_key
159 set the default key on an interface
160 set_default_mgmt_key
162 set the default management frame key on an interface
163 start_ap
165 Start acting in AP mode defined by the parameters.
166 change_beacon
168 Change the beacon parameters for an access point mode interface.
169 This should reject the call when AP mode wasn't started.
170 stop_ap
172 Stop being an AP, including stopping beaconing.
173 add_station
175 Add a new station.
176 del_station
178 Remove a station
179 change_station
181 Modify a given station. Note that flags changes are not much
182 validated in cfg80211, in particular the auth/assoc/authorized
183 flags might come to the driver in invalid combinations -- make sure
184 to check them, also against the existing state! Drivers must call
185 cfg80211_check_station_change to validate the information.
186 get_station
188 get station information for the station identified by mac
189 dump_station
191 dump station callback -- resume dump at index idx
192 add_mpath
194 add a fixed mesh path
195 del_mpath
197 delete a given mesh path
198 change_mpath
200 change a given mesh path
201 get_mpath
203 get a mesh path for the given parameters
204 dump_mpath
206 dump mesh path callback -- resume dump at index idx
207 get_mpp
209 get a mesh proxy path for the given parameters
210 dump_mpp
212 dump mesh proxy path callback -- resume dump at index idx
213 get_mesh_config
215 Get the current mesh configuration
216 update_mesh_config
218 Update mesh parameters on a running mesh. The mask is a bitfield
219 which tells us which parameters to set, and which to leave alone.
220 join_mesh
222 join the mesh network with the specified parameters (invoked with
223 the wireless_dev mutex held)
224 leave_mesh
226 leave the current mesh network (invoked with the wireless_dev mutex
227 held)
228 join_ocb
230 join the OCB network with the specified parameters (invoked with
231 the wireless_dev mutex held)
232 leave_ocb
234 leave the current OCB network (invoked with the wireless_dev mutex
235 held)
236 change_bss
238 Modify parameters for a given BSS.
239 set_txq_params
241 Set TX queue parameters
242 libertas_set_mesh_channel
244 Only for backward compatibility for libertas, as it doesn't
245 implement join_mesh and needs to set the channel to join the mesh
246 instead.
247 set_monitor_channel
249 Set the monitor mode channel for the device. If other interfaces
250 are active this callback should reject the configuration. If no
251 interfaces are active or the device is down, the channel should be
252 stored for when a monitor interface becomes active.
253 scan
255 Request to do a scan. If returning zero, the scan request is given
256 the driver, and will be valid until passed to cfg80211_scan_done.
257 For scan results, call cfg80211_inform_bss; you can call this
258 outside the scan/scan_done bracket too.
259 abort_scan
261 Tell the driver to abort an ongoing scan. The driver shall indicate
262 the status of the scan through cfg80211_scan_done.
263 auth
265 Request to authenticate with the specified peer (invoked with the
266 wireless_dev mutex held)
267 assoc
269 Request to (re)associate with the specified peer (invoked with the
270 wireless_dev mutex held)
271 deauth
273 Request to deauthenticate from the specified peer (invoked with the
274 wireless_dev mutex held)
275 disassoc
277 Request to disassociate from the specified peer (invoked with the
278 wireless_dev mutex held)
279 connect
281 Connect to the ESS with the specified parameters. When connected,
282 call cfg80211_connect_result/cfg80211_connect_bss with status code
283 WLAN_STATUS_SUCCESS. If the connection fails for some reason, call
284 cfg80211_connect_result/cfg80211_connect_bss with the status code
285 from the AP or cfg80211_connect_timeout if no frame with status
286 code was received. The driver is allowed to roam to other BSSes
287 within the ESS when the other BSS matches the connect parameters.
288 When such roaming is initiated by the driver, the driver is
289 expected to verify that the target matches the configured security
290 parameters and to use Reassociation Request frame instead of
291 Association Request frame. The connect function can also be used to
292 request the driver to perform a specific roam when connected to an
293 ESS. In that case, the prev_bssid parameter is set to the BSSID of
294 the currently associated BSS as an indication of requesting
295 reassociation. In both the driver-initiated and new connect call
296 initiated roaming cases, the result of roaming is indicated with a
297 call to cfg80211_roamed. (invoked with the wireless_dev mutex held)
298 update_connect_params
300 Update the connect parameters while connected to a BSS. The updated
301 parameters can be used by driver/firmware for subsequent BSS
302 selection (roaming) decisions and to form the
303 Authentication/(Re)Association Request frames. This call does not
304 request an immediate disassociation or reassociation with the
305 current BSS, i.e., this impacts only subsequent (re)associations.
306 The bits in changed are defined in enum
307 cfg80211_connect_params_changed. (invoked with the wireless_dev
308 mutex held)
309 disconnect
311 Disconnect from the BSS/ESS or stop connection attempts if
312 connection is in progress. Once done, call cfg80211_disconnected in
313 case connection was already established (invoked with the
314 wireless_dev mutex held), otherwise call cfg80211_connect_timeout.
315 join_ibss
317 Join the specified IBSS (or create if necessary). Once done, call
318 cfg80211_ibss_joined, also call that function when changing BSSID
319 due to a merge. (invoked with the wireless_dev mutex held)
320 leave_ibss
322 Leave the IBSS. (invoked with the wireless_dev mutex held)
323 set_mcast_rate
325 Set the specified multicast rate (only if vif is in ADHOC or MESH
326 mode)
327 set_wiphy_params
329 Notify that wiphy parameters have changed; changed bitfield (see
330 enum wiphy_params_flags) describes which values have changed. The
331 actual parameter values are available in struct wiphy. If returning
332 an error, no value should be changed.
333 set_tx_power
335 set the transmit power according to the parameters, the power
336 passed is in mBm, to get dBm use MBM_TO_DBM. The wdev may be NULL
337 if power was set for the wiphy, and will always be NULL unless the
338 driver supports per-vif TX power (as advertised by the nl80211
339 feature flag.)
340 get_tx_power
342 store the current TX power into the dbm variable; return 0 if
343 successful
344 set_wds_peer
346 set the WDS peer for a WDS interface
347 rfkill_poll
349 polls the hw rfkill line, use cfg80211 reporting functions to
350 adjust rfkill hw state
351 testmode_cmd
353 run a test mode command; wdev may be NULL
354 testmode_dump
356 Implement a test mode dump. The cb->args[2] and up may be used by
357 the function, but 0 and 1 must not be touched. Additionally, return
358 error codes other than -ENOBUFS and -ENOENT will terminate the dump
359 and return to userspace with an error, so be careful. If any data
360 was passed in from userspace then the data/len arguments will be
361 present and point to the data contained in NL80211_ATTR_TESTDATA.
362 set_bitrate_mask
364 set the bitrate mask configuration
365 dump_survey
367 get site survey information.
368 set_pmksa
370 Cache a PMKID for a BSSID. This is mostly useful for fullmac
371 devices running firmwares capable of generating the (re)
372 association RSN IE. It allows for faster roaming between WPA2
373 BSSIDs.
374 del_pmksa
376 Delete a cached PMKID.
377 flush_pmksa
379 Flush all cached PMKIDs.
380 remain_on_channel
382 Request the driver to remain awake on the specified channel for the
383 specified duration to complete an off-channel operation (e.g.,
384 public action frame exchange). When the driver is ready on the
385 requested channel, it must indicate this with an event notification
386 by calling cfg80211_ready_on_channel.
387 cancel_remain_on_channel
389 Cancel an on-going remain-on-channel operation. This allows the
390 operation to be terminated prior to timeout based on the duration
391 value.
392 mgmt_tx
394 Transmit a management frame.
395 mgmt_tx_cancel_wait
397 Cancel the wait time from transmitting a management frame on
398 another channel
399 set_power_mgmt
401 Configure WLAN power management. A timeout value of -1 allows the
402 driver to adjust the dynamic ps timeout value.
403 set_cqm_rssi_config
405 Configure connection quality monitor RSSI threshold. After
406 configuration, the driver should (soon) send an event indicating
407 the current level is above/below the configured threshold; this may
408 need some care when the configuration is changed (without first
409 being disabled.)
410 set_cqm_rssi_range_config
412 Configure two RSSI thresholds in the connection quality monitor. An
413 event is to be sent only when the signal level is found to be
414 outside the two values. The driver should set
415 NL80211_EXT_FEATURE_CQM_RSSI_LIST if this method is implemented. If
416 it is provided then there's no point providing set_cqm_rssi_config.
417 set_cqm_txe_config
419 Configure connection quality monitor TX error thresholds.
420 mgmt_frame_register
422 Notify driver that a management frame type was registered. The
423 callback is allowed to sleep.
424 set_antenna
426 Set antenna configuration (tx_ant, rx_ant) on the device.
427 Parameters are bitmaps of allowed antennas to use for TX/RX.
428 Drivers may reject TX/RX mask combinations they cannot support by
429 returning -EINVAL (also see nl80211.h
430 NL80211_ATTR_WIPHY_ANTENNA_TX).
431 get_antenna
433 Get current antenna configuration from device (tx_ant, rx_ant).
434 sched_scan_start
436 Tell the driver to start a scheduled scan.
437 sched_scan_stop
439 Tell the driver to stop an ongoing scheduled scan with given
440 request id. This call must stop the scheduled scan and be ready for
441 starting a new one before it returns, i.e. sched_scan_start may be
442 called immediately after that again and should not fail in that
443 case. The driver should not call cfg80211_sched_scan_stopped for a
444 requested stop (when this method returns 0).
445 set_rekey_data
447 give the data necessary for GTK rekeying to the driver
448 tdls_mgmt
450 Transmit a TDLS management frame.
451 tdls_oper
453 Perform a high-level TDLS operation (e.g. TDLS link setup).
454 probe_client
456 probe an associated client, must return a cookie that it later
457 passes to cfg80211_probe_status.
458 set_noack_map
460 Set the NoAck Map for the TIDs.
461 get_channel
463 Get the current operating channel for the virtual interface. For
464 monitor interfaces, it should return NULL unless there's a single
465 current monitoring channel.
466 start_p2p_device
468 Start the given P2P device.
469 stop_p2p_device
471 Stop the given P2P device.
472 set_mac_acl
474 Sets MAC address control list in AP and P2P GO mode. Parameters
475 include ACL policy, an array of MAC address of stations and the
476 number of MAC addresses. If there is already a list in driver this
477 new list replaces the existing one. Driver has to clear its ACL
478 when number of MAC addresses entries is passed as 0. Drivers which
479 advertise the support for MAC based ACL have to implement this
480 callback.
481 start_radar_detection
483 Start radar detection in the driver.
484 update_ft_ies
486 Provide updated Fast BSS Transition information to the driver. If
487 the SME is in the driver/firmware, this information can be used in
488 building Authentication and Reassociation Request frames.
489 crit_proto_start
491 Indicates a critical protocol needs more link reliability for a
492 given duration (milliseconds). The protocol is provided so the
493 driver can take the most appropriate actions.
494 crit_proto_stop
496 Indicates critical protocol no longer needs increased link
497 reliability. This operation can not fail.
498 set_coalesce
500 Set coalesce parameters.
501 channel_switch
503 initiate channel-switch procedure (with CSA). Driver is responsible
504 for veryfing if the switch is possible. Since this is inherently
505 tricky driver may decide to disconnect an interface later with
506 cfg80211_stop_iface. This doesn't mean driver can accept
507 everything. It should do it's best to verify requests and reject
508 them as soon as possible.
509 set_qos_map
511 Set QoS mapping information to the driver
512 set_ap_chanwidth
514 Set the AP (including P2P GO) mode channel width for the given
515 interface This is used e.g. for dynamic HT 20/40 MHz channel width
516 changes during the lifetime of the BSS.
517 add_tx_ts
519 validate (if admitted_time is 0) or add a TX TS to the device with
520 the given parameters; action frame exchange has been handled by
521 userspace so this just has to modify the TX path to take the TS
522 into account. If the admitted time is 0 just validate the
523 parameters to make sure the session can be created at all; it is
524 valid to just always return success for that but that may result in
525 inefficient behaviour (handshake with the peer followed by
526 immediate teardown when the addition is later rejected)
527 del_tx_ts
529 remove an existing TX TS
530 tdls_channel_switch
532 Start channel-switching with a TDLS peer. The driver is responsible
533 for continually initiating channel-switching operations and
534 returning to the base channel for communication with the AP.
535 tdls_cancel_channel_switch
537 Stop channel-switching with a TDLS peer. Both peers must be on the
538 base channel when the call completes.
539 start_nan
541 Start the NAN interface.
542 stop_nan
544 Stop the NAN interface.
545 add_nan_func
547 Add a NAN function. Returns negative value on failure. On success
548 nan_func ownership is transferred to the driver and it may access
549 it outside of the scope of this function. The driver should free
550 the nan_func when no longer needed by calling
551 cfg80211_free_nan_func. On success the driver should assign an
552 instance_id in the provided nan_func.
553 del_nan_func
555 Delete a NAN function.
556 nan_change_conf
558 changes NAN configuration. The changed parameters must be specified
559 in changes (using enum cfg80211_nan_conf_changes); All other
560 parameters must be ignored.
561 set_multicast_to_unicast
563 configure multicast to unicast conversion for BSS
564 set_pmk
566 configure the PMK to be used for offloaded 802.1X 4-Way handshake.
567 If not deleted through del_pmk the PMK remains valid until
568 disconnect upon which the driver should clear it. (invoked with the
569 wireless_dev mutex held)
570 del_pmk
572 delete the previously configured PMK for the given authenticator.
573 (invoked with the wireless_dev mutex held)
574
576 This struct is registered by fullmac card drivers and/or wireless
577 stacks in order to handle configuration requests on their interfaces.
578 All callbacks except where otherwise noted should return 0 on success
580 or a negative error code.
581 All operations are currently invoked under rtnl for consistency with
583 the wireless extensions but this is subject to reevaluation as soon as
584 this code is used more widely and we have a first user without wext.
