Function Documentation

void eap_set_eapRespData (  struct eap_sm *  sm, const u8 *  eapRespData, size_t  eapRespDataLen )

Set EAP response (eapRespData). Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() eapRespData  EAP-Response payload from the supplicant eapRespDataLen  Length of eapRespData in bytes This function is called when an EAP-Response is received from a supplicant. Definition at line 900 of file eap.c. Here is the call graph for this function:

void eap_sm_deinit (  struct eap_sm *  sm  )

Deinitialize and free an EAP state machine. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() This function deinitializes EAP state machine and frees all allocated resources. Definition at line 965 of file eap.c. Here is the call graph for this function:

struct eap_sm* eap_sm_init (  void *  eapol_ctx, struct eapol_callbacks *  eapol_cb, struct eap_config *  conf )

Allocate and initialize EAP state machine. Parameters: eapol_ctx  Context data to be used with eapol_cb calls eapol_cb  Pointer to EAPOL callback functions conf  EAP configuration Returns: Pointer to the allocated EAP state machine or NULL on failure This function allocates and initializes an EAP state machine. Definition at line 936 of file eap.c. Here is the call graph for this function:

int eap_sm_method_pending (  struct eap_sm *  sm  )

Query whether EAP method is waiting for pending data. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() Returns: 1 if method is waiting for pending data or 0 if not Definition at line 1022 of file eap.c.

void eap_sm_notify_cached (  struct eap_sm *  sm  )

Notify EAP state machine of cached PMK. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() This function is called when PMKSA caching is used to skip EAP authentication. Definition at line 990 of file eap.c.

void eap_sm_pending_cb (  struct eap_sm *  sm  )

EAP state machine callback for a pending EAP request. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() This function is called when data for a pending EAP-Request is received. Definition at line 1006 of file eap.c. Here is the call graph for this function:

int eap_sm_step (  struct eap_sm *  sm  )

Step EAP state machine. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() Returns: 1 if EAP state was changed or 0 if not This function advances EAP state machine to a new state to match with the current variables. This should be called whenever variables used by the EAP state machine have changed. Definition at line 878 of file eap.c.
