Detailed Description

Callback functions from EAP to lower layer.

This structure defines the callback functions that EAP state machine requires from the lower layer (usually EAPOL state machine) for updating state variables and requesting information. eapol_ctx from eap_sm_init() call will be used as the ctx parameter for these callback functions.

Definition at line 147 of file eap.h.

Field Documentation

Boolean(* eapol_callbacks::get_bool)(void *ctx, enum eapol_bool_var variable)

Get a boolean EAPOL state variable. Parameters: variable  EAPOL boolean variable to get Returns: Value of the EAPOL variable

struct wpa_ssid*(* eapol_callbacks::get_config)(void *ctx)

Get pointer to the current network configuration. Parameters: ctx  eapol_ctx from eap_sm_init() call

const struct wpa_config_blob*(* eapol_callbacks::get_config_blob)(void *ctx, const char *name)

Get a named configuration blob. Parameters: ctx  eapol_ctx from eap_sm_init() call name  Name of the blob Returns: Pointer to blob data or NULL if not found

u8*(* eapol_callbacks::get_eapReqData)(void *ctx, size_t *len)

Get EAP-Request data. Parameters: ctx  eapol_ctx from eap_sm_init() call len  Pointer to variable that will be set to eapReqDataLen Returns: Reference to eapReqData (EAP state machine will not free this) or NULL if eapReqData not available.

unsigned int(* eapol_callbacks::get_int)(void *ctx, enum eapol_int_var variable)

Get an integer EAPOL state variable. Parameters: ctx  eapol_ctx from eap_sm_init() call variable  EAPOL integer variable to get Returns: Value of the EAPOL variable

void(* eapol_callbacks::notify_pending)(void *ctx)

Notify that a pending request can be retried. Parameters: ctx  eapol_ctx from eap_sm_init() call An EAP method can perform a pending operation (e.g., to get a response from an external process). Once the response is available, this callback function can be used to request EAPOL state machine to retry delivering the previously received (and still unanswered) EAP request to EAP state machine.

void(* eapol_callbacks::set_bool)(void *ctx, enum eapol_bool_var variable, Boolean value)

Set a boolean EAPOL state variable. Parameters: ctx  eapol_ctx from eap_sm_init() call variable  EAPOL boolean variable to set value  Value for the EAPOL variable

void(* eapol_callbacks::set_config_blob)(void *ctx, struct wpa_config_blob *blob)

Set named configuration blob. Parameters: ctx  eapol_ctx from eap_sm_init() call blob  New value for the blob Adds a new configuration blob or replaces the current value of an existing blob.

void(* eapol_callbacks::set_int)(void *ctx, enum eapol_int_var variable, unsigned int value)

Set an integer EAPOL state variable. Parameters: ctx  eapol_ctx from eap_sm_init() call variable  EAPOL integer variable to set value  Value for the EAPOL variable
