|
|

|
|
* cfg80211 is the configuration API for 802.11 devices in Linux. It bridges
|
|
* userspace and drivers, and offers some utility functionality associated
|
|
* with 802.11. cfg80211 must, directly or indirectly via mac80211, be used
|
|
* by all modern wireless drivers in Linux, so that they offer a consistent
|
|
* API through nl80211. For backward compatibility, cfg80211 also offers
|
|
* wireless extensions to userspace, but hides them from drivers completely.
|
|
*
|
|
* Additionally, cfg80211 contains code to help enforce regulatory spectrum
|
|
* use restrictions.

/**

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

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

|
* code is used more widely and we have a first user without wext.
|
|
*
|
|
* @suspend: wiphy device needs to be suspended. The variable @wow will

|
* configured for the device.
|
|
* @resume: wiphy device needs to be resumed
|
|
* @set_wakeup: Called when WoWLAN is enabled/disabled, use this callback

|
* the device.
|
|
*
|
|
* @add_virtual_intf: create a new virtual interface with the given name,
|
|
* must set the struct wireless_dev's iftype. Beware: You must create
|
|
* the new netdev in the wiphy's network namespace! Returns the struct
|
|
* wireless_dev, or an ERR_PTR. For P2P device wdevs, the driver must
|
|
* also set the address member in the wdev.
|
|
*
|
|
* @del_virtual_intf: remove the virtual interface

|
|
*
|
|
* @start_ap: Start acting in AP mode defined by the parameters.
|
|
* @change_beacon: Change the beacon parameters for an access point mode
|
|
* interface. This should reject the call when AP mode wasn't started.
|
|
* @stop_ap: Stop being an AP, including stopping beaconing.
|
|
*
|
|
* @add_station: Add a new station.
|
|
* @del_station: Remove a station
|
|
* @change_station: Modify a given station. Note that flags changes are not much
|
|
* validated in cfg80211, in particular the auth/assoc/authorized flags
|
|

* cfg80211_check_station_change() to validate the information.
|
|
* @get_station: get station information for the station identified by @mac
|
|
* @dump_station: dump station callback -- resume dump at index @idx

|
*
|
|
* @add_mpath: add a fixed mesh path
|
|
* @del_mpath: delete a given mesh path
|

*
|
|
* @get_mesh_config: Get the current mesh configuration
|
|
*
|
|
* @update_mesh_config: Update mesh parameters on a running mesh.
|
|
* The mask is a bitfield which tells us which parameters to
|
|
* set, and which to leave alone.
|
|
*
|
|
* @change_bss: Modify parameters for a given BSS.
|
|
*
|
|
* @set_txq_params: Set TX queue parameters
|
|
*
|
|
* @libertas_set_mesh_channel: Only for backward compatibility for libertas,
|
|
* as it doesn't implement join_mesh and needs to set the channel to
|
|
* join the mesh instead.
|
|
*
|
|
* @set_monitor_channel: Set the monitor mode channel for the device. If other
|
|
* interfaces are active this callback should reject the configuration.
|
|
* If no interfaces are active or the device is down, the channel should
|
|
* be stored for when a monitor interface becomes active.
|
|
*
|
|
* @scan: Request to do a scan. If returning zero, the scan request is given
|
|
* the driver, and will be valid until passed to cfg80211_scan_done().
|
|
* For scan results, call cfg80211_inform_bss(); you can call this outside
|
|
* the scan/scan_done bracket too.
|
|
* @abort_scan: Tell the driver to abort an ongoing scan. The driver shall
|
|
* indicate the status of the scan through cfg80211_scan_done().
|
|
*
|
|
* @auth: Request to authenticate with the specified peer
|
|
* (invoked with the wireless_dev mutex held)
|
|
* @assoc: Request to (re)associate with the specified peer
|
|
* (invoked with the wireless_dev mutex held)
|
|
* @deauth: Request to deauthenticate from the specified peer
|
|
* (invoked with the wireless_dev mutex held)
|
|
* @disassoc: Request to disassociate from the specified peer
|
|
* (invoked with the wireless_dev mutex held)
|
|
*
|
|
* @connect: Connect to the ESS with the specified parameters. When connected,
|
|
* call cfg80211_connect_result()/cfg80211_connect_bss() with status code
|
|
* %WLAN_STATUS_SUCCESS. If the connection fails for some reason, call
|
|
* cfg80211_connect_result()/cfg80211_connect_bss() with the status code
|
|
* from the AP or cfg80211_connect_timeout() if no frame with status code
|
|
* was received.
|
|
* The driver is allowed to roam to other BSSes within the ESS when the
|
|
* other BSS matches the connect parameters. When such roaming is initiated
|
|
* by the driver, the driver is expected to verify that the target matches
|
|
* the configured security parameters and to use Reassociation Request
|
|
* frame instead of Association Request frame.
|
|
* The connect function can also be used to request the driver to perform a
|
|
* specific roam when connected to an ESS. In that case, the prev_bssid
|
|
* parameter is set to the BSSID of the currently associated BSS as an
|
|
* indication of requesting reassociation.
|
|
* In both the driver-initiated and new connect() call initiated roaming
|
|
* cases, the result of roaming is indicated with a call to
|
|
* cfg80211_roamed() or cfg80211_roamed_bss().
|
|
* (invoked with the wireless_dev mutex held)
|
|
* @disconnect: Disconnect from the BSS/ESS. Once done, call
|
|
* cfg80211_disconnected().
|
|
* (invoked with the wireless_dev mutex held)
|
|
*
|
|
* @join_ibss: Join the specified IBSS (or create if necessary). Once done, call
|
|
* cfg80211_ibss_joined(), also call that function when changing BSSID due
|
|
* to a merge.
|
|
* (invoked with the wireless_dev mutex held)
|
|
* @leave_ibss: Leave the IBSS.
|
|
* (invoked with the wireless_dev mutex held)
|
|
*
|
|
* @set_mcast_rate: Set the specified multicast rate (only if vif is in ADHOC or
|
|
* MESH mode)
|
|
*
|
|
* @set_wiphy_params: Notify that wiphy parameters have changed;
|
|
* @changed bitfield (see &enum wiphy_params_flags) describes which values
|
|
* have changed. The actual parameter values are available in
|
|
* struct wiphy. If returning an error, no value should be changed.
|
|
*
|
|
* @set_tx_power: set the transmit power according to the parameters,
|
|
* the power passed is in mBm, to get dBm use MBM_TO_DBM(). The
|
|
* wdev may be %NULL if power was set for the wiphy, and will
|
|
* always be %NULL unless the driver supports per-vif TX power
|
|
* (as advertised by the nl80211 feature flag.)
|
|
* @get_tx_power: store the current TX power into the dbm variable;
|
|
* return 0 if successful
|
|
*
|
|
* @set_wds_peer: set the WDS peer for a WDS interface
|
|
*
|
|
* @rfkill_poll: polls the hw rfkill line, use cfg80211 reporting
|
|
* functions to adjust rfkill hw state
|
|
*
|
|
* @dump_survey: get site survey information.
|
|
*
|
|
* @remain_on_channel: Request the driver to remain awake on the specified
|
|
* channel for the specified duration to complete an off-channel
|
|
* operation (e.g., public action frame exchange). When the driver is
|
|
* ready on the requested channel, it must indicate this with an event
|
|
* notification by calling cfg80211_ready_on_channel().
|
|
* @cancel_remain_on_channel: Cancel an on-going remain-on-channel operation.
|
|
* This allows the operation to be terminated prior to timeout based on
|
|
* the duration value.
|
|
* @mgmt_tx: Transmit a management frame.
|
|
* @mgmt_tx_cancel_wait: Cancel the wait time from transmitting a management
|
|
* frame on another channel
|
|
*
|
|
* @testmode_cmd: run a test mode command; @wdev may be %NULL
|
|
* @testmode_dump: Implement a test mode dump. The cb->args[2] and up may be
|
|
* used by the function, but 0 and 1 must not be touched. Additionally,
|
|
* return error codes other than -ENOBUFS and -ENOENT will terminate the
|
|
* dump and return to userspace with an error, so be careful. If any data
|
|
* was passed in from userspace then the data/len arguments will be present
|
|
* and point to the data contained in %NL80211_ATTR_TESTDATA.
|
|
*
|
|
* @set_bitrate_mask: set the bitrate mask configuration
|
|
*
|
|
* @set_pmksa: Cache a PMKID for a BSSID. This is mostly useful for fullmac
|
|
* devices running firmwares capable of generating the (re) association
|
|
* RSN IE. It allows for faster roaming between WPA2 BSSIDs.
|
|
* @del_pmksa: Delete a cached PMKID.
|
|
* @flush_pmksa: Flush all cached PMKIDs.
|
|
* @set_power_mgmt: Configure WLAN power management. A timeout value of -1
|
|
* allows the driver to adjust the dynamic ps timeout value.
|
|
* @set_cqm_rssi_config: Configure connection quality monitor RSSI threshold.
|
|
* After configuration, the driver should (soon) send an event indicating
|
|
* the current level is above/below the configured threshold; this may
|
|
* need some care when the configuration is changed (without first being
|
|
* disabled.)
|
|
* @set_cqm_txe_config: Configure connection quality monitor TX error
|
|
* thresholds.
|
|
* @sched_scan_start: Tell the driver to start a scheduled scan.
|
|
* @sched_scan_stop: Tell the driver to stop an ongoing scheduled scan. This
|
|
* call must stop the scheduled scan and be ready for starting a new one
|
|
* before it returns, i.e. @sched_scan_start may be called immediately
|
|
* after that again and should not fail in that case. The driver should
|
|
* not call cfg80211_sched_scan_stopped() for a requested stop (when this
|
|
* method returns 0.)
|
|
*
|
|
* @mgmt_frame_register: Notify driver that a management frame type was
|
|
* registered. The callback is allowed to sleep.
|
|
*
|
|
* @set_antenna: Set antenna configuration (tx_ant, rx_ant) on the device.
|
|
* Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers may
|
|
* reject TX/RX mask combinations they cannot support by returning -EINVAL
|
|
* (also see nl80211.h @NL80211_ATTR_WIPHY_ANTENNA_TX).
|
|
*
|
|
* @get_antenna: Get current antenna configuration from device (tx_ant, rx_ant).
|
|
*
|
|
* @tdls_mgmt: Transmit a TDLS management frame.
|
|
* @tdls_oper: Perform a high-level TDLS operation (e.g. TDLS link setup).
|
|
*
|
|
* @probe_client: probe an associated client, must return a cookie that it
|
|
* later passes to cfg80211_probe_status().
|
|
*
|
|
* @set_noack_map: Set the NoAck Map for the TIDs.
|
|
*
|
|
* @get_channel: Get the current operating channel for the virtual interface.
|
|
* For monitor interfaces, it should return %NULL unless there's a single
|
|
* current monitoring channel.
|
|
*
|
|
* @start_p2p_device: Start the given P2P device.
|
|
* @stop_p2p_device: Stop the given P2P device.
|
|
*
|
|
* @set_mac_acl: Sets MAC address control list in AP and P2P GO mode.
|
|
* Parameters include ACL policy, an array of MAC address of stations
|
|
* and the number of MAC addresses. If there is already a list in driver
|
|
* this new list replaces the existing one. Driver has to clear its ACL
|
|
* when number of MAC addresses entries is passed as 0. Drivers which
|
|
* advertise the support for MAC based ACL have to implement this callback.
|
|
*
|
|
* @start_radar_detection: Start radar detection in the driver.
|
|
*
|
|
* @update_ft_ies: Provide updated Fast BSS Transition information to the
|
|
* driver. If the SME is in the driver/firmware, this information can be
|
|
* used in building Authentication and Reassociation Request frames.
|
|
*
|
|
* @crit_proto_start: Indicates a critical protocol needs more link reliability
|
|
* for a given duration (milliseconds). The protocol is provided so the
|
|
* driver can take the most appropriate actions.
|
|
* @crit_proto_stop: Indicates critical protocol no longer needs increased link
|
|
* reliability. This operation can not fail.
|
|
* @set_coalesce: Set coalesce parameters.
|
|
*
|
|
* @channel_switch: initiate channel-switch procedure (with CSA). Driver is
|
|
* responsible for veryfing if the switch is possible. Since this is
|
|
* inherently tricky driver may decide to disconnect an interface later
|
|
* with cfg80211_stop_iface(). This doesn't mean driver can accept
|
|
* everything. It should do it's best to verify requests and reject them
|
|
* as soon as possible.
|
|
*
|
|
* @set_qos_map: Set QoS mapping information to the driver
|
|
*
|
|
* @set_ap_chanwidth: Set the AP (including P2P GO) mode channel width for the
|
|
* given interface This is used e.g. for dynamic HT 20/40 MHz channel width
|
|
* changes during the lifetime of the BSS.
|
|
*
|
|
* @add_tx_ts: validate (if admitted_time is 0) or add a TX TS to the device
|
|
* with the given parameters; action frame exchange has been handled by
|
|
* userspace so this just has to modify the TX path to take the TS into
|
|
* account.
|
|
* If the admitted time is 0 just validate the parameters to make sure
|
|
* the session can be created at all; it is valid to just always return
|
|
* success for that but that may result in inefficient behaviour (handshake
|
|
