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

3642 * both of these events at the same time, it can also include the
3643 * assoc_info data in EVENT_ASSOC call.
3648 * EVENT_DISASSOC - Association lost
3650 * This event should be called when association is lost either due to
3651 * receiving deauthenticate or disassociate frame from the AP or when
3652 * sending either of these frames to the current AP. If the driver
3653 * supports separate deauthentication event, EVENT_DISASSOC should only
3654 * be used for disassociation and EVENT_DEAUTH for deauthentication.
3655 * In AP mode, union wpa_event_data::disassoc_info is required.
3660 * EVENT_MICHAEL_MIC_FAILURE - Michael MIC (TKIP) detected
3662 * This event must be delivered when a Michael MIC error is detected by
3663 * the local driver. Additional data for event processing is

3673 * This event must be called whenever scan results are available to be
3674 * fetched with struct wpa_driver_ops::get_scan_results(). This event
3675 * is expected to be used some time after struct wpa_driver_ops::scan()
3676 * is called. If the driver provides an unsolicited event when the scan
3677 * has been completed, this event can be used to trigger
3678 * EVENT_SCAN_RESULTS call. If such event is not available from the
3679 * driver, the driver wrapper code is expected to use a registered

3708 EVENT_INTERFACE_STATUS,
3711 * EVENT_PMKID_CANDIDATE - Report a candidate AP for pre-authentication
3713 * This event can be used to inform wpa_supplicant about candidates for
3714 * RSN (WPA2) pre-authentication. If wpa_supplicant is not responsible
3715 * for scan request (ap_scan=2 mode), this event is required for
3716 * pre-authentication. If wpa_supplicant is performing scan request
3717 * (ap_scan=1), this event is optional since scan results can be used
3718 * to add pre-authentication candidates. union
3719 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
3720 * candidate and priority of the candidate, e.g., based on the signal
3721 * strength, in order to try to pre-authenticate first with candidates
3722 * that are most likely targets for re-association.
3724 * EVENT_PMKID_CANDIDATE can be called whenever the driver has updates
3725 * on the candidate list. In addition, it can be called for the current
3726 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
3727 * will automatically skip pre-authentication in cases where a valid
3728 * PMKSA exists. When more than one candidate exists, this event should
3729 * be generated once for each candidate.

3740 * up secure direct link connection between two stations as defined in
3741 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
3742 * STAKey negotiation. The caller will need to set peer address for the
3748 * EVENT_TDLS - Request TDLS operation
3750 * This event can be used to request a TDLS operation to be performed.
3755 * EVENT_FT_RESPONSE - Report FT (IEEE 802.11r) response IEs
3757 * The driver is expected to report the received FT IEs from
3758 * FT authentication sequence from the AP. The FT IEs are included in
3759 * the extra information in union wpa_event_data::ft_ies.
3764 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
3766 * The driver can use this event to inform wpa_supplicant about a STA
3767 * in an IBSS with which protected frames could be exchanged. This
3768 * event starts RSN authentication with the other STA to authenticate
3769 * the STA and set up encryption keys with it.
3771 EVENT_IBSS_RSN_START,
3774 * EVENT_AUTH - Authentication result
3776 * This event should be called when authentication attempt has been
3777 * completed. This is only used if the driver supports separate
3778 * authentication step (struct wpa_driver_ops::authenticate).
3779 * Information about authentication result is included in
3780 * union wpa_event_data::auth.
3785 * EVENT_DEAUTH - Authentication lost
3787 * This event should be called when authentication is lost either due
3788 * to receiving deauthenticate frame from the AP or when sending that
3789 * frame to the current AP.
3790 * In AP mode, union wpa_event_data::deauth_info is required.
3795 * EVENT_ASSOC_REJECT - Association rejected

3838 * operation is included in union wpa_event_data::remain_on_channel.
3840 EVENT_REMAIN_ON_CHANNEL,
3843 * EVENT_CANCEL_REMAIN_ON_CHANNEL - Remain-on-channel timed out
3845 * This event is used to indicate when the driver has completed
3846 * remain-on-channel duration, i.e., may noot be available on the
3847 * requested channel anymore. Information about the
3848 * operation is included in union wpa_event_data::remain_on_channel.
3850 EVENT_CANCEL_REMAIN_ON_CHANNEL,
3853 * EVENT_RX_PROBE_REQ - Indicate received Probe Request frame
3855 * This event is used to indicate when a Probe Request frame has been
3856 * received. Information about the received frame is included in
3857 * union wpa_event_data::rx_probe_req. The driver is required to report
3858 * these events only after successfully completed probe_req_report()
3859 * commands to request the events (i.e., report parameter is non-zero)
3860 * in station mode. In AP mode, Probe Request frames should always be
3866 * EVENT_NEW_STA - New wired device noticed
3868 * This event is used to indicate that a new device has been detected
3869 * in a network that does not use association-like functionality (i.e.,
3870 * mainly wired Ethernet). This can be used to start EAPOL
3871 * authenticator when receiving a frame from a device. The address of
3872 * the device is included in union wpa_event_data::new_sta.
3877 * EVENT_EAPOL_RX - Report received EAPOL frame

3914 * results including an AP advertising a country code.
3916 EVENT_CHANNEL_LIST_CHANGED,
3919 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
3921 * This event is used to indicate that the driver cannot maintain this
3922 * interface in its operation mode anymore. The most likely use for
3923 * this is to indicate that AP mode operation is not available due to
3924 * operating channel would need to be changed to a DFS channel when
3925 * the driver does not support radar detection and another virtual
3926 * interfaces caused the operating channel to change. Other similar
3927 * resource conflicts could also trigger this for station mode
3928 * interfaces. This event can be propagated when channel switching
3931 EVENT_INTERFACE_UNAVAILABLE,
3934 * EVENT_BEST_CHANNEL
3936 * Driver generates this event whenever it detects a better channel
3937 * (e.g., based on RSSI or channel use). This information can be used
3938 * to improve channel selection for a new AP/P2P group.
3943 * EVENT_UNPROT_DEAUTH - Unprotected Deauthentication frame received
3945 * This event should be called when a Deauthentication frame is dropped
