14 * This file defines a driver interface used by both %wpa_supplicant and
15 * hostapd. The first part of the file defines data structures used in various
16 * driver operations. This is followed by the struct wpa_driver_ops that each
17 * driver wrapper will beed to define with callback functions for requesting
18 * driver operations. After this, there are definitions for driver event
19 * reporting with wpa_supplicant_event() and some convenience helper functions
20 * that can be used to report events.

1632 * the interface mode (e.g., AP vs. station) is not yet known, but the
1633 * address of the virtual interface is already needed. This helps with
1634 * drivers that cannot change interface mode without destroying and
1635 * re-creating the interface. If the driver requires a specific
1636 * interface name to be used, the ifname buffer (up to IFNAMSIZ
1637 * characters) will be used to indicate which name must be used for
1638 * this virtual interface.

1647 * @priv: Private driver interface data
1648 * @addr: Address to be freed from alloc_interface_addr()
1650 * This command is used to release a virtual interface address that was
1651 * allocated with alloc_interface_addr(), but has not yet been used
1652 * with if_add() to actually create the interface. This allows the
1653 * driver to release the pending allocation for a new interface.

1666 * Action frames with EVENT_RX_ACTION events. Optionally, received
1667 * Probe Request frames may also be requested to be reported by calling

1670 * The driver may not be at the requested channel when this function
1671 * returns, i.e., the return code is only indicating whether the
1672 * request was accepted. The caller will need to wait until the
1673 * EVENT_REMAIN_ON_CHANNEL event indicates that the driver has
1674 * completed the channel change. This may take some time due to other
1675 * need for the radio and the caller should be prepared to timing out

1684 * @priv: Private driver interface data
1686 * This command can be used to cancel a remain-on-channel operation
1687 * before its originally requested duration has passed. This could be
1688 * used, e.g., when remain_on_channel() is used to request extra time
1689 * to receive a response to an Action frame and the response is
1690 * received when there is still unneeded time remaining on the
1691 * remain-on-channel operation.

1701 * This command can be used to request the driver to indicate when
1702 * Probe Request frames are received with EVENT_RX_PROBE_REQ events.
1703 * Since this operation may require extra resources, e.g., due to less
1704 * optimal hardware/firmware RX filtering, many drivers may disable
1705 * Probe Request reporting at least in station mode. This command is

1714 * @disabled: Whether IEEE 802.11b rates are disabled
1715 * Returns: 0 on success, -1 on failure (or if not supported)
1717 * This command is used to disable IEEE 802.11b rates (1, 2, 5.5, and
1718 * 11 Mbps) as TX rates for data and management frames. This can be
1719 * used to optimize channel use when there is no need to support IEEE

1726 * @priv: Private driver interface data
1727 * Returns: 0 on success, -1 on failure (or if not supported)
1729 * This optional function can be used to disable AP mode related
1730 * configuration and change the driver mode to station mode to allow
1731 * normal station operations like scanning to be completed.

1754 * EVENT_ASSOC - Association completed
1756 * This event needs to be delivered when the driver completes IEEE
1757 * 802.11 association or reassociation successfully.
1758 * wpa_driver_ops::get_bssid() is expected to provide the current BSSID
1759 * after this event has been generated. In addition, optional
1760 * EVENT_ASSOCINFO may be generated just before EVENT_ASSOC to provide
1761 * more information about the association. If the driver interface gets
1762 * both of these events at the same time, it can also include the
1763 * assoc_info data in EVENT_ASSOC call.
1768 * EVENT_DISASSOC - Association lost
1770 * This event should be called when association is lost either due to
1771 * receiving deauthenticate or disassociate frame from the AP or when
1772 * sending either of these frames to the current AP. If the driver
1773 * supports separate deauthentication event, EVENT_DISASSOC should only
1774 * be used for disassociation and EVENT_DEAUTH for deauthentication.
1775 * In AP mode, union wpa_event_data::disassoc_info is required.
1780 * EVENT_MICHAEL_MIC_FAILURE - Michael MIC (TKIP) detected
1782 * This event must be delivered when a Michael MIC error is detected by
1783 * the local driver. Additional data for event processing is
1784 * provided with union wpa_event_data::michael_mic_failure. This
1785 * information is used to request new encyption key and to initiate
1786 * TKIP countermeasures if needed.
1788 EVENT_MICHAEL_MIC_FAILURE,
1791 * EVENT_SCAN_RESULTS - Scan results available
1793 * This event must be called whenever scan results are available to be
1794 * fetched with struct wpa_driver_ops::get_scan_results(). This event
1795 * is expected to be used some time after struct wpa_driver_ops::scan()
1796 * is called. If the driver provides an unsolicited event when the scan
1797 * has been completed, this event can be used to trigger
1798 * EVENT_SCAN_RESULTS call. If such event is not available from the
1799 * driver, the driver wrapper code is expected to use a registered
1800 * timeout to generate EVENT_SCAN_RESULTS call after the time that the
1801 * scan is expected to be completed. Optional information about
1802 * completed scan can be provided with union wpa_event_data::scan_info.
1807 * EVENT_ASSOCINFO - Report optional extra information for association
1809 * This event can be used to report extra association information for
1810 * EVENT_ASSOC processing. This extra information includes IEs from
1811 * association frames and Beacon/Probe Response frames in union
1812 * wpa_event_data::assoc_info. EVENT_ASSOCINFO must be send just before
1813 * EVENT_ASSOC. Alternatively, the driver interface can include
1814 * assoc_info data in the EVENT_ASSOC call if it has all the
1815 * information available at the same point.
1820 * EVENT_INTERFACE_STATUS - Report interface status changes
1822 * This optional event can be used to report changes in interface
1823 * status (interface added/removed) using union
1824 * wpa_event_data::interface_status. This can be used to trigger
1825 * wpa_supplicant to stop and re-start processing for the interface,
1826 * e.g., when a cardbus card is ejected/inserted.
1828 EVENT_INTERFACE_STATUS,
1831 * EVENT_PMKID_CANDIDATE - Report a candidate AP for pre-authentication
1833 * This event can be used to inform wpa_supplicant about candidates for
1834 * RSN (WPA2) pre-authentication. If wpa_supplicant is not responsible
1835 * for scan request (ap_scan=2 mode), this event is required for
1836 * pre-authentication. If wpa_supplicant is performing scan request
1837 * (ap_scan=1), this event is optional since scan results can be used
1838 * to add pre-authentication candidates. union
1839 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
1840 * candidate and priority of the candidate, e.g., based on the signal
1841 * strength, in order to try to pre-authenticate first with candidates
1842 * that are most likely targets for re-association.
1844 * EVENT_PMKID_CANDIDATE can be called whenever the driver has updates
1845 * on the candidate list. In addition, it can be called for the current
1846 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
1847 * will automatically skip pre-authentication in cases where a valid
1848 * PMKSA exists. When more than one candidate exists, this event should
1849 * be generated once for each candidate.
1851 * Driver will be notified about successful pre-authentication with
1852 * struct wpa_driver_ops::add_pmkid() calls.
1854 EVENT_PMKID_CANDIDATE,
1857 * EVENT_STKSTART - Request STK handshake (MLME-STKSTART.request)
1859 * This event can be used to inform wpa_supplicant about desire to set
1860 * up secure direct link connection between two stations as defined in
1861 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
1862 * STAKey negotiation. The caller will need to set peer address for the
1868 * EVENT_FT_RESPONSE - Report FT (IEEE 802.11r) response IEs
1870 * The driver is expected to report the received FT IEs from
1871 * FT authentication sequence from the AP. The FT IEs are included in
1872 * the extra information in union wpa_event_data::ft_ies.
1877 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
1879 * The driver can use this event to inform wpa_supplicant about a STA
1880 * in an IBSS with which protected frames could be exchanged. This
1881 * event starts RSN authentication with the other STA to authenticate
1882 * the STA and set up encryption keys with it.
1884 EVENT_IBSS_RSN_START,
1887 * EVENT_AUTH - Authentication result
1889 * This event should be called when authentication attempt has been
1890 * completed. This is only used if the driver supports separate
1891 * authentication step (struct wpa_driver_ops::authenticate).
1892 * Information about authentication result is included in
1893 * union wpa_event_data::auth.
1898 * EVENT_DEAUTH - Authentication lost
1900 * This event should be called when authentication is lost either due
1901 * to receiving deauthenticate frame from the AP or when sending that
1902 * frame to the current AP.
1903 * In AP mode, union wpa_event_data::deauth_info is required.
1908 * EVENT_ASSOC_REJECT - Association rejected
1910 * This event should be called when (re)association attempt has been
1911 * rejected by the AP. Information about authentication result is
1912 * included in union wpa_event_data::assoc_reject.
1917 * EVENT_AUTH_TIMED_OUT - Authentication timed out
1919 EVENT_AUTH_TIMED_OUT,
1922 * EVENT_ASSOC_TIMED_OUT - Association timed out
1924 EVENT_ASSOC_TIMED_OUT,

1964 * requested remain-on-channel duration. Information about the
1965 * operation is included in union wpa_event_data::remain_on_channel.
1967 EVENT_REMAIN_ON_CHANNEL,
1970 * EVENT_CANCEL_REMAIN_ON_CHANNEL - Remain-on-channel timed out
1972 * This event is used to indicate when the driver has completed
1973 * remain-on-channel duration, i.e., may noot be available on the
1974 * requested channel anymore. Information about the
1975 * operation is included in union wpa_event_data::remain_on_channel.
1977 EVENT_CANCEL_REMAIN_ON_CHANNEL,
1980 * EVENT_MLME_RX - Report reception of frame for MLME (test use only)
1982 * This event is used only by driver_test.c and userspace MLME.
1987 * EVENT_RX_PROBE_REQ - Indicate received Probe Request frame
1989 * This event is used to indicate when a Probe Request frame has been
1990 * received. Information about the received frame is included in
1991 * union wpa_event_data::rx_probe_req. The driver is required to report
1992 * these events only after successfully completed probe_req_report()
1993 * commands to request the events (i.e., report parameter is non-zero)
1994 * in station mode. In AP mode, Probe Request frames should always be
2000 * EVENT_NEW_STA - New wired device noticed
2002 * This event is used to indicate that a new device has been detected
2003 * in a network that does not use association-like functionality (i.e.,
2004 * mainly wired Ethernet). This can be used to start EAPOL
2005 * authenticator when receiving a frame from a device. The address of
2006 * the device is included in union wpa_event_data::new_sta.
2011 * EVENT_EAPOL_RX - Report received EAPOL frame
2013 * When in AP mode with hostapd, this event is required to be used to
2014 * deliver the receive EAPOL frames from the driver. With
2015 * %wpa_supplicant, this event is used only if the send_eapol() handler
2016 * is used to override the use of l2_packet for EAPOL frame TX.

2025 union wpa_event_data {
2027 * struct assoc_info - Data for EVENT_ASSOC and EVENT_ASSOCINFO events
2029 * This structure is optional for EVENT_ASSOC calls and required for
2030 * EVENT_ASSOCINFO calls. By using EVENT_ASSOC with this data, the
2031 * driver interface does not need to generate separate EVENT_ASSOCINFO
2036 * req_ies - (Re)Association Request IEs
2038 * If the driver generates WPA/RSN IE, this event data must be
2039 * returned for WPA handshake to have needed information. If
2040 * wpa_supplicant-generated WPA/RSN IE is used, this
2041 * information event is optional.
2043 * This should start with the first IE (fixed fields before IEs
2044 * are not included).
2049 * req_ies_len - Length of req_ies in bytes
2054 * resp_ies - (Re)Association Response IEs
2056 * Optional association data from the driver. This data is not
2057 * required WPA, but may be useful for some protocols and as
2058 * such, should be reported if this is available to the driver
