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

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

*
* @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
* regulatory domain.
* @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
* after being queried by the kernel. CRDA replies by sending a regulatory
* domain structure which consists of %NL80211_ATTR_REG_ALPHA set to our
* current alpha2 if it found a match. It also provides
* NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each

*
* @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the
* interface identified by %NL80211_ATTR_IFINDEX
*
* @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
* interface identified by %NL80211_ATTR_IFINDEX
*
* @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
* interface is identified with %NL80211_ATTR_IFINDEX and the management
* frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
* added to the end of the specified management frame is specified with
* %NL80211_ATTR_IE. If the command succeeds, the requested data will be
* added to all specified management frames generated by
* kernel/firmware/driver.
* Note: This command has been removed and it is only reserved at this
* point to avoid re-using existing command number. The functionality this
* command was planned for has been provided with cleaner design with the
* option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
* NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
* NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
*
* @NL80211_CMD_GET_SCAN: get scan results
* @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
* %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
* probe requests at CCK rate or not.
* @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
* NL80211_CMD_GET_SCAN and on the "scan" multicast group)
* @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
* partial scan results may be available
*
* @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
* intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
* Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
* are passed, they are used in the probe requests. For
* broadcast, a broadcast SSID must be passed (ie. an empty
* string). If no SSID is passed, no probe requests are sent and
* a passive scan is performed. %NL80211_ATTR_SCAN_FREQUENCIES,
* if passed, define which channels should be scanned; if not
* passed, all channels allowed for the current regulatory domain
* are used. Extra IEs can also be passed from the userspace by
* using the %NL80211_ATTR_IE attribute.
* @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT
* if scheduled scan is not running.
* @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
* results available.
* @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
* stopped. The driver may issue this event at any time during a
* scheduled scan. One reason for stopping the scan is if the hardware
* does not support starting an association or a normal scan while running
* a scheduled scan. This event is also sent when the
* %NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
* is brought down while a scheduled scan was running.
*
* @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
* or noise level
* @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
* NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
*
* @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
* (for the BSSID) and %NL80211_ATTR_PMKID.
* @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
* (for the BSSID) and %NL80211_ATTR_PMKID.
* @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
*
* @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
* has been changed and provides details of the request information
* that caused the change such as who initiated the regulatory request
* (%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
* (%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
* the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
* %NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
* set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
* %NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
* to (%NL80211_ATTR_REG_ALPHA2).
* @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
* has been found while world roaming thus enabling active scan or
* any mode of operation that initiates TX (beacons) on a channel
* where we would not have been able to do either before. As an example
* if you are world roaming (regulatory domain set to world or if your
* driver is using a custom world roaming regulatory domain) and while
* doing a passive scan on the 5 GHz band you find an AP there (if not
* on a DFS channel) you will now be able to actively scan for that AP
* or use AP mode on your card on that same channel. Note that this will
* never be used for channels 1-11 on the 2 GHz band as they are always
* enabled world wide. This beacon hint is only sent if your device had
* either disabled active scanning or beaconing on a channel. We send to
* userspace the wiphy on which we removed a restriction from
* (%NL80211_ATTR_WIPHY) and the channel on which this occurred
* before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
* the beacon hint was processed.
*
* @NL80211_CMD_AUTHENTICATE: authentication request and notification.
* This command is used both as a command (request to authenticate) and
* as an event on the "mlme" multicast group indicating completion of the
* authentication process.
* When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
* interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
* BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
* the SSID (mainly for association, but is included in authentication
* request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
* to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
* is used to specify the authentication type. %NL80211_ATTR_IE is used to
* define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
* to be added to the frame.
* When used as an event, this reports reception of an Authentication
* frame in station and IBSS modes when the local MLME processed the
* frame, i.e., it was for the local STA and was received in correct
* state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
* MLME SAP interface (kernel providing MLME, userspace SME). The
* included %NL80211_ATTR_FRAME attribute contains the management frame
* (including both the header and frame body, but not FCS). This event is
* also used to indicate if the authentication attempt timed out. In that
* case the %NL80211_ATTR_FRAME attribute is replaced with a
* %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
* pending authentication timed out).
* @NL80211_CMD_ASSOCIATE: association request and notification; like
* NL80211_CMD_AUTHENTICATE but for Association and Reassociation
* (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
* MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
* @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
* NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
* MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
* primitives).
* @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
* NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
* MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
*
* @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
* MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
* event includes %NL80211_ATTR_MAC to describe the source MAC address of
* the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
* type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
* %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
* event matches with MLME-MICHAELMICFAILURE.indication() primitive
*
* @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
* FREQ attribute (for the initial frequency if no peer can be found)
* and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
* should be fixed rather than automatically determined. Can only be
* executed on a network interface that is UP, and fixed BSSID/FREQ
* may be rejected. Another optional parameter is the beacon interval,
* given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
* given defaults to 100 TU (102.4ms).
* @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
* determined by the network interface.
*
* @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
* to identify the device, and the TESTDATA blob attribute to pass through
* to the driver.
*
* @NL80211_CMD_CONNECT: connection request and notification; this command
* requests to connect to a specified network but without separating
* auth and assoc steps. For this, you need to specify the SSID in a
* %NL80211_ATTR_SSID attribute, and can optionally specify the association
* IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
* %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
* %NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
* %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
* Background scan period can optionally be
* specified in %NL80211_ATTR_BG_SCAN_PERIOD,
* if not specified default background scan configuration
* in driver is used and if period value is 0, bg scan will be disabled.
* This attribute is ignored if driver does not support roam scan.
* It is also sent as an event, with the BSSID and response IEs when the
* connection is established or failed to be established. This can be
* determined by the STATUS_CODE attribute.
* @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
* sent as an event when the card/driver roamed by itself.
* @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
* userspace that a connection was dropped by the AP or due to other
* reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
* %NL80211_ATTR_REASON_CODE attributes are used.
*
* @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
* associated with this wiphy must be down and will follow.
*
* @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
* channel for the specified amount of time. This can be used to do
* off-channel operations like transmit a Public Action frame and wait for
* a response while being associated to an AP on another channel.
* %NL80211_ATTR_IFINDEX is used to specify which interface (and thus
* radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
* frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
* optionally used to specify additional channel parameters.
* %NL80211_ATTR_DURATION is used to specify the duration in milliseconds
* to remain on the channel. This command is also used as an event to
* notify when the requested duration starts (it may take a while for the
* driver to schedule this time due to other concurrent needs for the
* radio).
* When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
* that will be included with any events pertaining to this request;
* the cookie is also used to cancel the request.
* @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
* pending remain-on-channel duration if the desired operation has been
* completed prior to expiration of the originally requested duration.
* %NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
* radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
* uniquely identify the request.
* This command is also used as an event to notify when a requested
* remain-on-channel duration has expired.
*
* @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
* rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
* and @NL80211_ATTR_TX_RATES the set of allowed rates.
*
* @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
* (via @NL80211_CMD_FRAME) for processing in userspace. This command
* requires an interface index, a frame type attribute (optional for
* backward compatibility reasons, if not given assumes action frames)
* and a match attribute containing the first few bytes of the frame
* that should match, e.g. a single byte for only a category match or
* four bytes for vendor frames including the OUI. The registration
* cannot be dropped, but is removed automatically when the netlink
* socket is closed. Multiple registrations can be made.
* @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
* backward compatibility
* @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
* command is used both as a request to transmit a management frame and
* as an event indicating reception of a frame that was not processed in
* kernel code, but is for us (i.e., which may need to be processed in a
* user space application). %NL80211_ATTR_FRAME is used to specify the
* frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
* optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
* which channel the frame is to be transmitted or was received. If this
* channel is not the current channel (remain-on-channel or the
* operational channel) the device will switch to the given channel and
* transmit the frame, optionally waiting for a response for the time
* specified using %NL80211_ATTR_DURATION. When called, this operation
* returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
* TX status event pertaining to the TX request.
* %NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
* management frames at CCK rate or not in 2GHz band.
* @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
* command may be used with the corresponding cookie to cancel the wait
* time if it is known that it is no longer necessary.
* @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
* @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
* transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
* the TX command and %NL80211_ATTR_FRAME includes the contents of the
* frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
* the frame.
* @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
* backward compatibility.
*
* @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
* @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
*
* @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
* is used to configure connection quality monitoring notification trigger
* levels.
* @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
* command is used as an event to indicate the that a trigger level was
* reached.
* @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
* and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
* by %NL80211_ATTR_IFINDEX) shall operate on.
* In case multiple channels are supported by the device, the mechanism
* with which it switches channels is implementation-defined.
* When a monitor interface is given, it can only switch channel while
* no other interfaces are operating to avoid disturbing the operation
* of any other interfaces, and other interfaces will again take
* precedence when they are used.
*
* @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
*
* @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
* mesh config parameters may be given.
* @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
* network is determined by the network interface.
*
* @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
* notification. This event is used to indicate that an unprotected
* deauthentication frame was dropped when MFP is in use.
* @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
* notification. This event is used to indicate that an unprotected
* disassociation frame was dropped when MFP is in use.
*
* @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
* beacon or probe response from a compatible mesh peer. This is only
* sent while no station information (sta_info) exists for the new peer
* candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set. On
* reception of this notification, userspace may decide to create a new
* station (@NL80211_CMD_NEW_STATION). To stop this notification from
* reoccurring, the userspace authentication daemon may want to create the
* new station with the AUTHENTICATED flag unset and maybe change it later
* depending on the authentication result.
*
* @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
* @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
* Since wireless is more complex than wired ethernet, it supports
* various triggers. These triggers can be configured through this
* command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
* more background information, see
* http://wireless.kernel.org/en/users/Documentation/WoWLAN.
*
* @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
* the necessary information for supporting GTK rekey offload. This
* feature is typically used during WoWLAN. The configuration data
* is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
* contains the data in sub-attributes). After rekeying happened,
* this command may also be sent by the driver as an MLME event to
* inform userspace of the new replay counter.
*
* @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
* of PMKSA caching dandidates.
*
* @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
* @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
*
* @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
* (or GO) interface (i.e. hostapd) to ask for unexpected frames to
* implement sending deauth to stations that send unexpected class 3
* frames. Also used as the event sent by the kernel when such a frame
* is received.
* For the event, the %NL80211_ATTR_MAC attribute carries the TA and
* other attributes like the interface index are present.
* If used as the command it must have an interface index and you can
* only unsubscribe from the event by closing the socket. Subscription
* is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
*
* @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
* associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
* and wasn't already in a 4-addr VLAN. The event will be sent similarly
* to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
*
* @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
* by sending a null data frame to it and reporting when the frame is
* acknowleged. This is used to allow timing out inactive clients. Uses
* %NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
* direct reply with an %NL80211_ATTR_COOKIE that is later used to match
* up the event with the request. The event includes the same data and
* has %NL80211_ATTR_ACK set if the frame was ACKed.
*
* @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
* other BSSes when any interfaces are in AP mode. This helps implement
* OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
* messages. Note that per PHY only one application may register.
*
* @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
* No Acknowledgement Policy should be applied.
*
* @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
