-1) Synopsis
------------
-
-wavemon is a wireless device monitoring application that allows you to watch
-signal and noise levels, packet statistics, device configuration and network
-parameters of your wireless network hardware. It should work (though with
-varying features) with all devices supported by the Linux wireless kernel
-extensions by Jean Tourrilhes.
-
-See the man page for an in-depth description of operation and configuration.
-
-
-2) Where to obtain
-------------------
-Apart from debian/ubuntu packages (apt-cache search wavemon) and slackbuild
-scripts for wavemon on slackbuilds.org, up-to-date sources are available at
-
- http://www.erg.abdn.ac.uk/ergcms/wavemon/
-
-Please check this page for updates and for further information.
-wavemon is distributed under the GPLv3, refer to the file COPYING.
-
-
-3) How to build
----------------
-wavemon uses autoconf, so that in most cases you can simply run
-
- ./configure
- make
- sudo make install
-
-to build and install the package. Type 'make uninstall' if not happy.
-Refer to the file INSTALL for generic installation instructions.
-
-To grant users access to restricted networking operations (e.g. reading WEP
-keys or performing scan operations), use additionally
-
- sudo make install-suid-root
-
-If you have changed some of the autoconf files or use a git version, run
- ./config/bootstrap
-(requires a recent installation of 'autotools').
-
-
-3) Bugs?
---------
-Send bug reports, comments, and suggestions to <gerrit@erg.abdn.ac.uk>.

+## Synopsis
+
+wavemon is a wireless device monitoring application that allows you to watch
+signal and noise levels, packet statistics, device configuration and network
+parameters of your wireless network hardware. It should work (though with
+varying features) with all devices supported by the Linux kernel.
+
+See the man page for an in-depth description of operation and configuration.
+
+
+### Where to obtain
+
+Apart from debian/ubuntu packages (apt-cache search wavemon) and slackbuild
+scripts for wavemon on slackbuilds.org, this repository contains the full
+source code.
+
+Please check this page for updates and for further information.
+wavemon is distributed under the [GPLv3](http://www.gnu.org/licenses/gpl-3.0.en.html), refer to the file `COPYING`.
+
+
+## How to build
+
+wavemon uses `autoconf`, so that in most cases you can simply run
+```
+ ./configure
+ make
+ sudo make install
+```
+to build and install the package. Type 'make uninstall' if not happy.
+Refer to the file `INSTALL` for generic installation instructions.
+
+**Dependencies**: at least version 3.2 of `libnl`, including the Generic Netlink support (`libnl-genl`).
+On Debian/Ubuntu, this can be done using
+```bash
+ apt-get -y install libnl-3-dev libnl-genl-3-dev
+```
+
+To grant users access to restricted networking operations (scan operations), use additionally
+```
+ sudo make install-suid-root
+```
+If you have changed some of the autoconf files or use a git version, run
+```
+ ./config/bootstrap
+```
+(requires a recent installation of `autotools`).
+
+
+## Bugs?

+ * DOC: Station handling

+ * Stations are added per interface, but a special case exists with VLAN

+ * into a VLAN identified by a VLAN interface index (%NL80211_ATTR_STA_VLAN).
+ * The station is still assumed to belong to the AP interface it was added
+ * to.
+ *
+ * Station handling varies per interface type and depending on the driver's
+ * capabilities.
+ *
+ * For drivers supporting TDLS with external setup (WIPHY_FLAG_SUPPORTS_TDLS
+ * and WIPHY_FLAG_TDLS_EXTERNAL_SETUP), the station lifetime is as follows:
+ * - a setup station entry is added, not yet authorized, without any rate
+ * or capability information, this just exists to avoid race conditions
+ * - when the TDLS setup is done, a single NL80211_CMD_SET_STATION is valid
+ * to add rate and capability information to the station and at the same
+ * time mark it authorized.
+ * - %NL80211_TDLS_ENABLE_LINK is then used
+ * - after this, the only valid operation is to remove it by tearing down
+ * the TDLS link (%NL80211_TDLS_DISABLE_LINK)

+/**
+ * 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.

+ * 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.

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

+ * @NL80211_CMD_SET_BSS: Set BSS attributes for BSS identified by
+ * %NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_GET_REG: ask the wireless core to send us its currently set
+ * regulatory domain. If %NL80211_ATTR_WIPHY is specified and the device
+ * has a private regulatory domain, it will be returned. Otherwise, the
+ * global regdomain will be returned.
+ * A device will have a private regulatory domain if it uses the
+ * regulatory_hint() API. Even when a private regdomain is used the channel
+ * information will still be mended according to further hints from
+ * the regulatory core to help with compliance. A dump version of this API
+ * is now available which will returns the global regdomain as well as
+ * all private regdomains of present wiphys (for those that have it).
+ * If a wiphy is self-managed (%NL80211_ATTR_WIPHY_SELF_MANAGED_REG), then
+ * its private regdomain is the only valid one for it. The regulatory
+ * core is not used to help with compliance in this case.
+ * @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
+ * regulatory rule is a nested set of attributes given by
+ * %NL80211_ATTR_REG_RULE_FREQ_[START|END] and
+ * %NL80211_ATTR_FREQ_RANGE_MAX_BW with an attached power rule given by
+ * %NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
+ * %NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
+ * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
+ * to the specified ISO/IEC 3166-1 alpha2 country code. The core will
+ * store this as a valid request and then query userspace for it.
+ *
+ * @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. The first cycle of the
+ * scheduled scan can be delayed by %NL80211_ATTR_SCHED_SCAN_DELAY
+ * is supplied.
+ * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan. Returns -ENOENT if
+ * scheduled scan is not running. The caller may assume that as soon
+ * as the call returns, it is safe to start a new scheduled scan again.
+ * @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_USE_MFP,
+ * %NL80211_ATTR_MAC, %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
+ * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE,
+ * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT, %NL80211_ATTR_MAC_HINT, and
+ * %NL80211_ATTR_WIPHY_FREQ_HINT.
+ * If included, %NL80211_ATTR_MAC and %NL80211_ATTR_WIPHY_FREQ are
+ * restrictions on BSS selection, i.e., they effectively prevent roaming
+ * within the ESS. %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT
+ * can be included to provide a recommendation of the initial BSS while
+ * allowing the driver to roam to other BSSes within the ESS and also to
+ * ignore this recommendation if the indicated BSS is not ideal. Only one
+ * set of BSSID,frequency parameters is used (i.e., either the enforcing
+ * %NL80211_ATTR_MAC,%NL80211_ATTR_WIPHY_FREQ or the less strict
+ * %NL80211_ATTR_MAC_HINT and %NL80211_ATTR_WIPHY_FREQ_HINT).
+ * 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.
+ * %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 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_ATTR_CSA_C_OFFSETS_TX is an array of offsets to CSA
+ * counters which will be updated to the current value. This attribute
+ * is used during CSA period.
+ * @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 the attributes determining channel width) 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,
+ * @NL80211_MESH_SETUP_USERSPACE_AMPE, or
+ * @NL80211_MESH_SETUP_USERSPACE_MPM 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.
+ * The @NL80211_CMD_SET_WOWLAN command can also be used as a notification
+ * from the driver reporting the wakeup reason. In this case, the
+ * @NL80211_ATTR_WOWLAN_TRIGGERS attribute will contain the reason
+ * for the wakeup, if it was caused by wireless. If it is not present
+ * in the wakeup notification, the wireless device didn't cause the
+ * wakeup but reports that it was woken up.
+ *
+ * @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).
+ * In addition, this can be used as an event to request userspace to take
+ * actions on TDLS links (set up a new link or tear down an existing one).
+ * In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
+ * operation, %NL80211_ATTR_MAC contains the peer MAC address, and
+ * %NL80211_ATTR_REASON_CODE the reason code to be used (only with
+ * %NL80211_TDLS_TEARDOWN).
+ * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame. The
+ * %NL80211_ATTR_TDLS_ACTION attribute determines the type of frame to be
+ * sent. Public Action codes (802.11-2012 8.1.5.1) will be sent as
+ * 802.11 management frames, while TDLS action codes (802.11-2012
+ * 8.5.13.1) will be encapsulated and sent as data frames. The currently
+ * supported Public Action code is %WLAN_PUB_ACTION_TDLS_DISCOVER_RES
+ * and the currently supported TDLS actions codes are given in
+ * &enum ieee80211_tdls_actioncode.
+ *
+ * @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
+ * independently of the userspace SME, send this event indicating
+ * %NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ and the
+ * attributes determining channel width. This indication may also be
+ * sent when a remotely-initiated switch (e.g., when a STA receives a CSA
+ * from the remote AP) is completed;
+ *
+ * @NL80211_CMD_CH_SWITCH_STARTED_NOTIFY: Notify that a channel switch
+ * has been started on an interface, regardless of the initiator
+ * (ie. whether it was requested from a remote device or
+ * initiated on our own). It indicates that
+ * %NL80211_ATTR_IFINDEX will be on %NL80211_ATTR_WIPHY_FREQ
+ * after %NL80211_ATTR_CH_SWITCH_COUNT TBTT's. The userspace may
+ * decide to react to this indication by requesting other
+ * interfaces to change channel as well.
+ *
+ * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
+ * its %NL80211_ATTR_WDEV identifier. It must have been created with
+ * %NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
+ * P2P Device can be used for P2P operations, e.g. remain-on-channel and
+ * public action frame TX.
+ * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
+ * its %NL80211_ATTR_WDEV identifier.
+ *
+ * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
+ * notify userspace that AP has rejected the connection request from a
+ * station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
+ * is used for this.
+ *
+ * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
+ * for IBSS or MESH vif.
+ *
+ * @NL80211_CMD_SET_MAC_ACL: sets ACL for MAC address based access control.
+ * This is to be used with the drivers advertising the support of MAC
+ * address based access control. List of MAC addresses is passed in
+ * %NL80211_ATTR_MAC_ADDRS and ACL policy is passed in
+ * %NL80211_ATTR_ACL_POLICY. Driver will enable ACL with this list, if it
+ * is not already done. The new list will replace any existing list. Driver
+ * will clear its ACL when the list of MAC addresses passed is empty. This
+ * command is used in AP/P2P GO mode. Driver has to make sure to clear its
+ * ACL list during %NL80211_CMD_STOP_AP.
+ *
+ * @NL80211_CMD_RADAR_DETECT: Start a Channel availability check (CAC). Once
+ * a radar is detected or the channel availability scan (CAC) has finished
+ * or was aborted, or a radar was detected, usermode will be notified with
+ * this event. This command is also used to notify userspace about radars
+ * while operating on this channel.
+ * %NL80211_ATTR_RADAR_EVENT is used to inform about the type of the
+ * event.
+ *
+ * @NL80211_CMD_GET_PROTOCOL_FEATURES: Get global nl80211 protocol features,
+ * i.e. features for the nl80211 protocol rather than device features.
+ * Returns the features in the %NL80211_ATTR_PROTOCOL_FEATURES bitmap.
+ *
+ * @NL80211_CMD_UPDATE_FT_IES: Pass down the most up-to-date Fast Transition
+ * Information Element to the WLAN driver
+ *
+ * @NL80211_CMD_FT_EVENT: Send a Fast transition event from the WLAN driver
+ * to the supplicant. This will carry the target AP's MAC address along
+ * with the relevant Information Elements. This event is used to report
+ * received FT IEs (MDIE, FTIE, RSN IE, TIE, RICIE).
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_START: Indicates user-space will start running
+ * a critical protocol that needs more reliability in the connection to
+ * complete.
+ *
+ * @NL80211_CMD_CRIT_PROTOCOL_STOP: Indicates the connection reliability can
+ * return back to normal.
+ *
+ * @NL80211_CMD_GET_COALESCE: Get currently supported coalesce rules.
+ * @NL80211_CMD_SET_COALESCE: Configure coalesce rules or clear existing rules.
+ *
+ * @NL80211_CMD_CHANNEL_SWITCH: Perform a channel switch by announcing the
+ * the new channel information (Channel Switch Announcement - CSA)
+ * in the beacon for some time (as defined in the
+ * %NL80211_ATTR_CH_SWITCH_COUNT parameter) and then change to the
+ * new channel. Userspace provides the new channel information (using
+ * %NL80211_ATTR_WIPHY_FREQ and the attributes determining channel
+ * width). %NL80211_ATTR_CH_SWITCH_BLOCK_TX may be supplied to inform
+ * other station that transmission must be blocked until the channel
+ * switch is complete.
+ *
+ * @NL80211_CMD_VENDOR: Vendor-specified command/event. The command is specified
+ * by the %NL80211_ATTR_VENDOR_ID attribute and a sub-command in
+ * %NL80211_ATTR_VENDOR_SUBCMD. Parameter(s) can be transported in
+ * %NL80211_ATTR_VENDOR_DATA.
+ * For feature advertisement, the %NL80211_ATTR_VENDOR_DATA attribute is
+ * used in the wiphy data as a nested attribute containing descriptions
+ * (&struct nl80211_vendor_cmd_info) of the supported vendor commands.
+ * This may also be sent as an event with the same attributes.
+ *
+ * @NL80211_CMD_SET_QOS_MAP: Set Interworking QoS mapping for IP DSCP values.
+ * The QoS mapping information is included in %NL80211_ATTR_QOS_MAP. If
+ * that attribute is not included, QoS mapping is disabled. Since this
+ * QoS mapping is relevant for IP packets, it is only valid during an
+ * association. This is cleared on disassociation and AP restart.
+ *
+ * @NL80211_CMD_ADD_TX_TS: Ask the kernel to add a traffic stream for the given
+ * %NL80211_ATTR_TSID and %NL80211_ATTR_MAC with %NL80211_ATTR_USER_PRIO
+ * and %NL80211_ATTR_ADMITTED_TIME parameters.
+ * Note that the action frame handshake with the AP shall be handled by
+ * userspace via the normal management RX/TX framework, this only sets
+ * up the TX TS in the driver/device.
+ * If the admitted time attribute is not added then the request just checks
+ * if a subsequent setup could be successful, the intent is to use this to
+ * avoid setting up a session with the AP when local restrictions would
+ * make that impossible. However, the subsequent "real" setup may still
+ * fail even if the check was successful.
+ * @NL80211_CMD_DEL_TX_TS: Remove an existing TS with the %NL80211_ATTR_TSID
+ * and %NL80211_ATTR_MAC parameters. It isn't necessary to call this
+ * before removing a station entry entirely, or before disassociating
+ * or similar, cleanup will happen in the driver/device in this case.
+ *
+ * @NL80211_CMD_GET_MPP: Get mesh path attributes for mesh proxy path to
+ * destination %NL80211_ATTR_MAC on the interface identified by
+ * %NL80211_ATTR_IFINDEX.
+ *
+ * @NL80211_CMD_JOIN_OCB: Join the OCB network. The center frequency and
+ * bandwidth of a channel must be given.
+ * @NL80211_CMD_LEAVE_OCB: Leave the OCB network -- no special arguments, the
+ * network is determined by the network interface.
+ *
+ * @NL80211_CMD_TDLS_CHANNEL_SWITCH: Start channel-switching with a TDLS peer,
+ * identified by the %NL80211_ATTR_MAC parameter. A target channel is
+ * provided via %NL80211_ATTR_WIPHY_FREQ and other attributes determining
+ * channel width/type. The target operating class is given via
+ * %NL80211_ATTR_OPER_CLASS.
+ * The driver is responsible for continually initiating channel-switching
+ * operations and returning to the base channel for communication with the
+ * AP.
+ * @NL80211_CMD_TDLS_CANCEL_CHANNEL_SWITCH: Stop channel-switching with a TDLS
+ * peer given by %NL80211_ATTR_MAC. Both peers must be on the base channel
+ * when this command completes.
+ *
+ * @NL80211_CMD_WIPHY_REG_CHANGE: Similar to %NL80211_CMD_REG_CHANGE, but used
+ * as an event to indicate changes for devices with wiphy-specific regdom
+ * management.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ * capabilities, the supported WoWLAN triggers
+ * @NL80211_ATTR_WOWLAN_TRIGGERS: used by %NL80211_CMD_SET_WOWLAN to

+ *
+ * @NL80211_ATTR_SCHED_SCAN_INTERVAL: Interval between scheduled scan
+ * cycles, in msecs.
+ *
+ * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
+ * sets of attributes to match during scheduled scans. Only BSSs
+ * that match any of the sets will be reported. These are
+ * pass-thru filter rules.
+ * For a match to succeed, the BSS must match all attributes of a
+ * set. Since not every hardware supports matching all types of
+ * attributes, there is no guarantee that the reported BSSs are
+ * fully complying with the match sets and userspace needs to be
+ * able to ignore them by itself.
+ * Thus, the implementation is somewhat hardware-dependent, but
+ * this is only an optimization and the userspace application
+ * needs to handle all the non-filtered results anyway.
+ * If the match attributes don't make sense when combined with
+ * the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
+ * is included in the probe request, but the match attributes
+ * will never let it go through), -EINVAL may be returned.

+/**
+ * DOC: TCP connection wakeup
+ *
+ * Some devices can establish a TCP connection in order to be woken up by a
+ * packet coming in from outside their network segment, or behind NAT. If
+ * configured, the device will establish a TCP connection to the given
+ * service, and periodically send data to that service. The first data
+ * packet is usually transmitted after SYN/ACK, also ACKing the SYN/ACK.
+ * The data packets can optionally include a (little endian) sequence
+ * number (in the TCP payload!) that is generated by the device, and, also
+ * optionally, a token from a list of tokens. This serves as a keep-alive
+ * with the service, and for NATed connections, etc.
+ *
+ * During this keep-alive period, the server doesn't send any data to the
+ * client. When receiving data, it is compared against the wakeup pattern
+ * (and mask) and if it matches, the host is woken up. Similarly, if the
+ * connection breaks or cannot be established to start with, the host is

+ * @NL80211_FEATURE_VIF_TXPOWER: The driver supports per-vif TX power setting
+ * @NL80211_FEATURE_NEED_OBSS_SCAN: The driver expects userspace to perform
+ * OBSS scans and generate 20/40 BSS coex reports. This flag is used only
+ * for drivers implementing the CONNECT API, for AUTH/ASSOC it is implied.
+ * @NL80211_FEATURE_P2P_GO_CTWIN: P2P GO implementation supports CT Window
+ * setting
+ * @NL80211_FEATURE_P2P_GO_OPPPS: P2P GO implementation supports opportunistic
+ * powersave
+ * @NL80211_FEATURE_FULL_AP_CLIENT_STATE: The driver supports full state
+ * transitions for AP clients. Without this flag (and if the driver
+ * doesn't have the AP SME in the device) the driver supports adding
+ * stations only when they're associated and adds them in associated
+ * state (to later be transitioned into authorized), with this flag

+ * and then transitioned into authenticated, associated and authorized
+ * states using station flags.
+ * Note that even for drivers that support this, the default is to add

+ * @NL80211_FEATURE_USERSPACE_MPM: This driver supports a userspace Mesh
+ * Peering Management entity which may be implemented by registering for
+ * beacons or NL80211_CMD_NEW_PEER_CANDIDATE events. The mesh beacon is
+ * still generated by the driver.
+ * @NL80211_FEATURE_ACTIVE_MONITOR: This driver supports an active monitor
+ * interface. An active monitor interface behaves like a normal monitor
+ * interface, but gets added to the driver. It ensures that incoming
+ * unicast packets directed at the configured interface address get ACKed.
+ * @NL80211_FEATURE_AP_MODE_CHAN_WIDTH_CHANGE: This driver supports dynamic
+ * channel bandwidth change (e.g., HT 20 <-> 40 MHz channel) during the
+ * lifetime of a BSS.
+ * @NL80211_FEATURE_DS_PARAM_SET_IE_IN_PROBES: This device adds a DS Parameter

+ * to probe requests.
+ * @NL80211_FEATURE_QUIET: This device, in client mode, supports Quiet Period
+ * requests sent to it by an AP.
+ * @NL80211_FEATURE_TX_POWER_INSERTION: This device is capable of inserting the
+ * current tx power value into the TPC Report IE in the spectrum
+ * management TPC Report action frame, and in the Radio Measurement Link
+ * Measurement Report action frame.
+ * @NL80211_FEATURE_ACKTO_ESTIMATION: This driver supports dynamic ACK timeout
+ * estimation (dynack). %NL80211_ATTR_WIPHY_DYN_ACK flag attribute is used
+ * to enable dynack.
+ * @NL80211_FEATURE_STATIC_SMPS: Device supports static spatial
+ * multiplexing powersave, ie. can turn off all but one chain
+ * even on HT connections that should be using more chains.
+ * @NL80211_FEATURE_DYNAMIC_SMPS: Device supports dynamic spatial
+ * multiplexing powersave, ie. can turn off all but one chain
+ * and then wake the rest up as required after, for example,
+ * rts/cts handshake.
+ * @NL80211_FEATURE_SUPPORTS_WMM_ADMISSION: the device supports setting up WMM
+ * TSPEC sessions (TID aka TSID 0-7) with the %NL80211_CMD_ADD_TX_TS

\fIwavemon\fR is a ncurses-based monitoring application for wireless network
devices. It plots levels in real-time as well as showing wireless and network

+The station-specific information includes the station type (ESS for Access Point,

A status line at the bottom informs about the current sort order and a few
statistics, such as most (least) crowded channels (least crowded channels
are listed when sorting by descending channel).
The \fIsort_order\fR can also directly be changed via these keyboard shortcuts:
\fIa\fRscending, \fId\fRescending; by \fIe\fRssid, \fIs\fRignal, \fIc\fRhannel (\fIC\fR also with signal),
