Function Documentation

u8* eap_tlv_build_nak (  int  id, u16  nak_type, size_t *  resp_len )

Build EAP-TLV NAK message. Parameters: id  EAP identifier for the header nak_type  TLV type (EAP_TLV_*) resp_len  Buffer for returning the response length Returns: Buffer to the allocated EAP-TLV NAK message or NULL on failure This funtion builds an EAP-TLV NAK message. The caller is responsible for freeing the returned buffer. Definition at line 37 of file eap_tlv.c.

u8* eap_tlv_build_result (  int  id, u16  status, size_t *  resp_len )

Build EAP-TLV Result message. Parameters: id  EAP identifier for the header status  Status (EAP_TLV_RESULT_SUCCESS or EAP_TLV_RESULT_FAILURE) resp_len  Buffer for returning the response length Returns: Buffer to the allocated EAP-TLV Result message or NULL on failure This funtion builds an EAP-TLV Result message. The caller is responsible for freeing the returned buffer. Definition at line 80 of file eap_tlv.c.

int eap_tlv_process (  struct eap_sm *  sm, struct eap_method_ret *  ret, const struct eap_hdr *  hdr, u8 **  resp, size_t *  resp_len )

Process a received EAP-TLV message and generate a response. Parameters: sm  Pointer to EAP state machine allocated with eap_sm_init() ret  Return values from EAP request validation and processing hdr  EAP-TLV request to be processed. The caller must have validated that the buffer is large enough to contain full request (hdr->length bytes) and that the EAP type is EAP_TYPE_TLV. resp  Buffer to return a pointer to the allocated response message. This field should be initialized to NULL before the call. The value will be updated if a response message is generated. The caller is responsible for freeing the allocated message. resp_len  Buffer for returning the response length Returns: 0 on success, -1 on failure Definition at line 122 of file eap_tlv.c.
