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.

3098 * EVENT_DISASSOC - Association lost
3100 * This event should be called when association is lost either due to
3101 * receiving deauthenticate or disassociate frame from the AP or when
3102 * sending either of these frames to the current AP. If the driver
3103 * supports separate deauthentication event, EVENT_DISASSOC should only
3104 * be used for disassociation and EVENT_DEAUTH for deauthentication.
3105 * In AP mode, union wpa_event_data::disassoc_info is required.
3110 * EVENT_MICHAEL_MIC_FAILURE - Michael MIC (TKIP) detected
3112 * This event must be delivered when a Michael MIC error is detected by
3113 * the local driver. Additional data for event processing is
3114 * provided with union wpa_event_data::michael_mic_failure. This

3121 * EVENT_SCAN_RESULTS - Scan results available
3123 * This event must be called whenever scan results are available to be
3124 * fetched with struct wpa_driver_ops::get_scan_results(). This event
3125 * is expected to be used some time after struct wpa_driver_ops::scan()

3127 * has been completed, this event can be used to trigger
3128 * EVENT_SCAN_RESULTS call. If such event is not available from the
3129 * driver, the driver wrapper code is expected to use a registered
3130 * timeout to generate EVENT_SCAN_RESULTS call after the time that the

3132 * completed scan can be provided with union wpa_event_data::scan_info.
3137 * EVENT_ASSOCINFO - Report optional extra information for association
3139 * This event can be used to report extra association information for
3140 * EVENT_ASSOC processing. This extra information includes IEs from
3141 * association frames and Beacon/Probe Response frames in union
3142 * wpa_event_data::assoc_info. EVENT_ASSOCINFO must be send just before
3143 * EVENT_ASSOC. Alternatively, the driver interface can include
3144 * assoc_info data in the EVENT_ASSOC call if it has all the
3145 * information available at the same point.

3152 * This optional event can be used to report changes in interface
3153 * status (interface added/removed) using union
3154 * wpa_event_data::interface_status. This can be used to trigger
3155 * wpa_supplicant to stop and re-start processing for the interface,

3158 EVENT_INTERFACE_STATUS,
3161 * EVENT_PMKID_CANDIDATE - Report a candidate AP for pre-authentication
3163 * This event can be used to inform wpa_supplicant about candidates for
3164 * RSN (WPA2) pre-authentication. If wpa_supplicant is not responsible
3165 * for scan request (ap_scan=2 mode), this event is required for
3166 * pre-authentication. If wpa_supplicant is performing scan request
3167 * (ap_scan=1), this event is optional since scan results can be used
3168 * to add pre-authentication candidates. union
3169 * wpa_event_data::pmkid_candidate is used to report the BSSID of the
3170 * candidate and priority of the candidate, e.g., based on the signal
3171 * strength, in order to try to pre-authenticate first with candidates
3172 * that are most likely targets for re-association.
3174 * EVENT_PMKID_CANDIDATE can be called whenever the driver has updates
3175 * on the candidate list. In addition, it can be called for the current
3176 * AP and APs that have existing PMKSA cache entries. wpa_supplicant
3177 * will automatically skip pre-authentication in cases where a valid
3178 * PMKSA exists. When more than one candidate exists, this event should
3179 * be generated once for each candidate.
3181 * Driver will be notified about successful pre-authentication with
3182 * struct wpa_driver_ops::add_pmkid() calls.
3184 EVENT_PMKID_CANDIDATE,
3187 * EVENT_STKSTART - Request STK handshake (MLME-STKSTART.request)

3209 * the extra information in union wpa_event_data::ft_ies.
3214 * EVENT_IBSS_RSN_START - Request RSN authentication in IBSS
3216 * The driver can use this event to inform wpa_supplicant about a STA
3217 * in an IBSS with which protected frames could be exchanged. This
3218 * event starts RSN authentication with the other STA to authenticate
3219 * the STA and set up encryption keys with it.
3221 EVENT_IBSS_RSN_START,
3224 * EVENT_AUTH - Authentication result
3226 * This event should be called when authentication attempt has been
3227 * completed. This is only used if the driver supports separate
3228 * authentication step (struct wpa_driver_ops::authenticate).
3229 * Information about authentication result is included in
3230 * union wpa_event_data::auth.
3235 * EVENT_DEAUTH - Authentication lost
3237 * This event should be called when authentication is lost either due
3238 * to receiving deauthenticate frame from the AP or when sending that
3239 * frame to the current AP.
3240 * In AP mode, union wpa_event_data::deauth_info is required.

3310 * This event is used only by driver_test.c and userspace MLME.
3315 * EVENT_RX_PROBE_REQ - Indicate received Probe Request frame
3317 * This event is used to indicate when a Probe Request frame has been
3318 * received. Information about the received frame is included in
3319 * union wpa_event_data::rx_probe_req. The driver is required to report
3320 * these events only after successfully completed probe_req_report()
3321 * commands to request the events (i.e., report parameter is non-zero)
3322 * in station mode. In AP mode, Probe Request frames should always be
3328 * EVENT_NEW_STA - New wired device noticed
3330 * This event is used to indicate that a new device has been detected
3331 * in a network that does not use association-like functionality (i.e.,
3332 * mainly wired Ethernet). This can be used to start EAPOL

3344 * is used to override the use of l2_packet for EAPOL frame TX.
3349 * EVENT_SIGNAL_CHANGE - Indicate change in signal strength
3351 * This event is used to indicate changes in the signal strength
3352 * observed in frames received from the current AP if signal strength
3353 * monitoring has been enabled with signal_monitor().
3355 EVENT_SIGNAL_CHANGE,
3358 * EVENT_INTERFACE_ENABLED - Notify that interface was enabled

3378 * results including an AP advertising a country code.
3380 EVENT_CHANNEL_LIST_CHANGED,
3383 * EVENT_INTERFACE_UNAVAILABLE - Notify that interface is unavailable
3385 * This event is used to indicate that the driver cannot maintain this
3386 * interface in its operation mode anymore. The most likely use for
3387 * this is to indicate that AP mode operation is not available due to
3388 * operating channel would need to be changed to a DFS channel when
3389 * the driver does not support radar detection and another virtual
3390 * interfaces caused the operating channel to change. Other similar
3391 * resource conflicts could also trigger this for station mode
3392 * interfaces. This event can be propagated when channel switching
3395 EVENT_INTERFACE_UNAVAILABLE,
3398 * EVENT_BEST_CHANNEL
3400 * Driver generates this event whenever it detects a better channel
3401 * (e.g., based on RSSI or channel use). This information can be used
3402 * to improve channel selection for a new AP/P2P group.
3407 * EVENT_UNPROT_DEAUTH - Unprotected Deauthentication frame received
3409 * This event should be called when a Deauthentication frame is dropped

3483 * EVENT_CONNECT_FAILED_REASON - Connection failure reason in AP mode
3485 * This event indicates that the driver reported a connection failure
3486 * with the specified client (for example, max client reached, etc.) in
3489 EVENT_CONNECT_FAILED_REASON,
3492 * EVENT_RADAR_DETECTED - Notify of radar detection
3494 * A radar has been detected on the supplied frequency, hostapd should
3495 * react accordingly (e.g., change channel).
3497 EVENT_DFS_RADAR_DETECTED,
3500 * EVENT_CAC_FINISHED - Notify that channel availability check has been completed
3502 * After a successful CAC, the channel can be marked clear and used.
3504 EVENT_DFS_CAC_FINISHED,
3507 * EVENT_CAC_ABORTED - Notify that channel availability check has been aborted
3509 * The CAC was not successful, and the channel remains in the previous
3510 * state. This may happen due to a radar beeing detected or other
3511 * external influences.

3525 * This event gets triggered when a driver query is issued for survey
3526 * data and the requested data becomes available. The returned data is
3527 * stored in struct survey_results. The results provide at most one
3528 * survey entry for each frequency and at minimum will provide one
3529 * survey entry for one frequency. The survey data can be os_malloc()'d
3530 * and then os_free()'d, so the event callback must only copy data.
3535 * EVENT_SCAN_STARTED - Scan started
3537 * This indicates that driver has started a scan operation either based
3538 * on a request from wpa_supplicant/hostapd or from another application.

3540 * completed (either successfully or by getting cancelled).
3545 * EVENT_AVOID_FREQUENCIES - Received avoid frequency range
3547 * This event indicates a set of frequency ranges that should be avoided
3548 * to reduce issues due to interference or internal co-existence
3549 * information in the driver.
