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.

3573 * both of these events at the same time, it can also include the
3574 * assoc_info data in EVENT_ASSOC call.
3579 * EVENT_DISASSOC - Association lost
3581 * This event should be called when association is lost either due to
3582 * receiving deauthenticate or disassociate frame from the AP or when
3583 * sending either of these frames to the current AP. If the driver
3584 * supports separate deauthentication event, EVENT_DISASSOC should only
3585 * be used for disassociation and EVENT_DEAUTH for deauthentication.
3586 * In AP mode, union wpa_event_data::disassoc_info is required.
3591 * EVENT_MICHAEL_MIC_FAILURE - Michael MIC (TKIP) detected
3593 * This event must be delivered when a Michael MIC error is detected by
3594 * the local driver. Additional data for event processing is
3595 * provided with union wpa_event_data::michael_mic_failure. This
3596 * information is used to request new encyption key and to initiate
3597 * TKIP countermeasures if needed.

3602 * EVENT_SCAN_RESULTS - Scan results available
3604 * This event must be called whenever scan results are available to be
3605 * fetched with struct wpa_driver_ops::get_scan_results(). This event
3606 * is expected to be used some time after struct wpa_driver_ops::scan()
3607 * is called. If the driver provides an unsolicited event when the scan
3608 * has been completed, this event can be used to trigger
3609 * EVENT_SCAN_RESULTS call. If such event is not available from the
3610 * driver, the driver wrapper code is expected to use a registered
3611 * timeout to generate EVENT_SCAN_RESULTS call after the time that the
3612 * scan is expected to be completed. Optional information about
3613 * completed scan can be provided with union wpa_event_data::scan_info.
3618 * EVENT_ASSOCINFO - Report optional extra information for association
3620 * This event can be used to report extra association information for
3621 * EVENT_ASSOC processing. This extra information includes IEs from
3622 * association frames and Beacon/Probe Response frames in union
3623 * wpa_event_data::assoc_info. EVENT_ASSOCINFO must be send just before

3626 * information available at the same point.
3631 * EVENT_INTERFACE_STATUS - Report interface status changes
3633 * This optional event can be used to report changes in interface
3634 * status (interface added/removed) using union
3635 * wpa_event_data::interface_status. This can be used to trigger
3636 * wpa_supplicant to stop and re-start processing for the interface,
3637 * e.g., when a cardbus card is ejected/inserted.
3639 EVENT_INTERFACE_STATUS,
3642 * EVENT_PMKID_CANDIDATE - Report a candidate AP for pre-authentication
3644 * This event can be used to inform wpa_supplicant about candidates for
3645 * RSN (WPA2) pre-authentication. If wpa_supplicant is not responsible
3646 * for scan request (ap_scan=2 mode), this event is required for
3647 * pre-authentication. If wpa_supplicant is performing scan request
3648 * (ap_scan=1), this event is optional since scan results can be used
3649 * to add pre-authentication candidates. union
3650 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
3651 * candidate and priority of the candidate, e.g., based on the signal
3652 * strength, in order to try to pre-authenticate first with candidates
3653 * that are most likely targets for re-association.
3655 * EVENT_PMKID_CANDIDATE can be called whenever the driver has updates
3656 * on the candidate list. In addition, it can be called for the current
3657 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
3658 * will automatically skip pre-authentication in cases where a valid
3659 * PMKSA exists. When more than one candidate exists, this event should
3660 * be generated once for each candidate.
3662 * Driver will be notified about successful pre-authentication with
3663 * struct wpa_driver_ops::add_pmkid() calls.
3665 EVENT_PMKID_CANDIDATE,
3668 * EVENT_STKSTART - Request STK handshake (MLME-STKSTART.request)
3670 * This event can be used to inform wpa_supplicant about desire to set
3671 * up secure direct link connection between two stations as defined in
3672 * IEEE 802.11e with a new PeerKey mechanism that replaced the original
3673 * STAKey negotiation. The caller will need to set peer address for the
3679 * EVENT_TDLS - Request TDLS operation
3681 * This event can be used to request a TDLS operation to be performed.
3686 * EVENT_FT_RESPONSE - Report FT (IEEE 802.11r) response IEs
3688 * The driver is expected to report the received FT IEs from
3689 * FT authentication sequence from the AP. The FT IEs are included in
3690 * the extra information in union wpa_event_data::ft_ies.
3695 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
3697 * The driver can use this event to inform wpa_supplicant about a STA
3698 * in an IBSS with which protected frames could be exchanged. This
3699 * event starts RSN authentication with the other STA to authenticate
3700 * the STA and set up encryption keys with it.
3702 EVENT_IBSS_RSN_START,
3705 * EVENT_AUTH - Authentication result
3707 * This event should be called when authentication attempt has been
3708 * completed. This is only used if the driver supports separate
3709 * authentication step (struct wpa_driver_ops::authenticate).
3710 * Information about authentication result is included in
3711 * union wpa_event_data::auth.
3716 * EVENT_DEAUTH - Authentication lost
3718 * This event should be called when authentication is lost either due
3719 * to receiving deauthenticate frame from the AP or when sending that
3720 * frame to the current AP.
3721 * In AP mode, union wpa_event_data::deauth_info is required.
3726 * EVENT_ASSOC_REJECT - Association rejected
3728 * This event should be called when (re)association attempt has been
3729 * rejected by the AP. Information about the association response is
3730 * included in union wpa_event_data::assoc_reject.
3735 * EVENT_AUTH_TIMED_OUT - Authentication timed out

3769 * operation is included in union wpa_event_data::remain_on_channel.
3771 EVENT_REMAIN_ON_CHANNEL,
3774 * EVENT_CANCEL_REMAIN_ON_CHANNEL - Remain-on-channel timed out
3776 * This event is used to indicate when the driver has completed
3777 * remain-on-channel duration, i.e., may noot be available on the
3778 * requested channel anymore. Information about the
3779 * operation is included in union wpa_event_data::remain_on_channel.
3781 EVENT_CANCEL_REMAIN_ON_CHANNEL,
3784 * EVENT_RX_PROBE_REQ - Indicate received Probe Request frame
3786 * This event is used to indicate when a Probe Request frame has been
3787 * received. Information about the received frame is included in
3788 * union wpa_event_data::rx_probe_req. The driver is required to report
3789 * these events only after successfully completed probe_req_report()
3790 * commands to request the events (i.e., report parameter is non-zero)
3791 * in station mode. In AP mode, Probe Request frames should always be
3797 * EVENT_NEW_STA - New wired device noticed
3799 * This event is used to indicate that a new device has been detected
3800 * in a network that does not use association-like functionality (i.e.,
3801 * mainly wired Ethernet). This can be used to start EAPOL
3802 * authenticator when receiving a frame from a device. The address of
3803 * the device is included in union wpa_event_data::new_sta.
3808 * EVENT_EAPOL_RX - Report received EAPOL frame

3845 * results including an AP advertising a country code.
3847 EVENT_CHANNEL_LIST_CHANGED,
3850 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
3852 * This event is used to indicate that the driver cannot maintain this
3853 * interface in its operation mode anymore. The most likely use for
3854 * this is to indicate that AP mode operation is not available due to
3855 * operating channel would need to be changed to a DFS channel when
3856 * the driver does not support radar detection and another virtual
3857 * interfaces caused the operating channel to change. Other similar
3858 * resource conflicts could also trigger this for station mode
3859 * interfaces. This event can be propagated when channel switching
3862 EVENT_INTERFACE_UNAVAILABLE,
3865 * EVENT_BEST_CHANNEL
3867 * Driver generates this event whenever it detects a better channel
3868 * (e.g., based on RSSI or channel use). This information can be used

3993 * data and the requested data becomes available. The returned data is
3994 * stored in struct survey_results. The results provide at most one
3995 * survey entry for each frequency and at minimum will provide one
3996 * survey entry for one frequency. The survey data can be os_malloc()'d
