Detailed Description

Data for EVENT_ASSOC and EVENT_ASSOCINFO events.

This structure is optional for EVENT_ASSOC calls and required for EVENT_ASSOCINFO calls. By using EVENT_ASSOC with this data, the driver interface does not need to generate separate EVENT_ASSOCINFO calls.

Field Documentation

int wpa_event_data::assoc_info::authorized

The following is the key management offload information.

Parameters

authorized	key_replay_ctr
key_replay_ctr_len	ptk_kck
ptk_kek_len	ptk_kek
ptk_kek_len	Status of key management offload, 1 = successful

const u8* wpa_event_data::assoc_info::beacon_ies

Beacon or Probe Response IEs.

Optional Beacon/ProbeResp data: IEs included in Beacon or Probe Response frames from the current AP (i.e., the one that the client just associated with). This information is used to update WPA/RSN IE for the AP. If this field is not set, the results from previous scan will be used. If no data for the new AP is found, scan results will be requested again (without scan request). At this point, the driver is expected to provide WPA/RSN IE for the AP (if WPA/WPA2 is used).

This should start with the first IE (fixed fields before IEs are not included).

const u8* wpa_event_data::assoc_info::req_ies

(Re)Association Request IEs

If the driver generates WPA/RSN IE, this event data must be returned for WPA handshake to have needed information. If wpa_supplicant-generated WPA/RSN IE is used, this information event is optional.

This should start with the first IE (fixed fields before IEs are not included).

const u8* wpa_event_data::assoc_info::resp_ies

(Re)Association Response IEs

Optional association data from the driver. This data is not required WPA, but may be useful for some protocols and as such, should be reported if this is available to the driver interface.

This should start with the first IE (fixed fields before IEs are not included).
