Fapi_NvExtend(3) tpm2-tss Fapi_NvExtend(3) NAME Fapi_NvExtend - Fapi_NvExtend SYNOPSIS Functions TSS2_RC Fapi_NvExtend (FAPI_CONTEXT *context, char const *path, uint8_t const *data, size_t size, char const *logData) TSS2_RC Fapi_NvExtend_Async (FAPI_CONTEXT *context, char const *path, uint8_t const *data, size_t size, char const *logData) TSS2_RC Fapi_NvExtend_Finish (FAPI_CONTEXT *context) Detailed Description FAPI functions to invoke NvExtend either as one-call or in an asynchronous manner. Function Documentation TSS2_RC Fapi_NvExtend (FAPI_CONTEXT * context, char const * nvPath, uint8_t const * data, size_t dataSize, char const * logData) One-Call function for Fapi_NvExtend Performs an extend operation on an NV index with the type extend. Parameters context the FAPI context nvPath The path to the NV index that is extended data The data to extend on the NV index dataSize The size of the data to extend. Must be smaller than 1024 logData A JSON representation of the data that is written to the event log. May be NULL Return values TSS2_RC_SUCCESS if the function call was a success. TSS2_FAPI_RC_BAD_REFERENCE if context, nvPath, or data is NULL. TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected. TSS2_FAPI_RC_BAD_PATH if nvPath is not found. TSS2_FAPI_RC_NV_WRONG_TYPE if the NV is not an extendable index. TSS2_FAPI_RC_POLICY_UNKNOWN if the policy is unknown. TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending. TSS2_FAPI_RC_IO_ERROR if the data cannot be saved. TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters. TSS2_FAPI_RC_NO_TPM if FAPI was initialized in no-TPM-mode via its config file. TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function. TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization. TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found. TSS2_FAPI_RC_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again. TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred. TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set. TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails. TSS2_ESYS_RC_* possible error codes of ESAPI. TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned. TSS2_RC Fapi_NvExtend_Async (FAPI_CONTEXT * context, char const * nvPath, uint8_t const * data, size_t dataSize, char const * logData) Asynchronous function for Fapi_NvExtend Performs an extend operation on an NV index with the type extend. Call Fapi_NvExtend_Finish to finish the execution of this command. Parameters context the FAPI context nvPath The path to the NV index that is extended data The data to extend on the NV index dataSize The size of the data to extend. Must be smaller than 1024 logData A JSON representation of the data that is written to the event log. May be NULL Return values TSS2_RC_SUCCESS if the function call was a success. TSS2_FAPI_RC_BAD_REFERENCE if context, nvPath, or data is NULL. TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected. TSS2_FAPI_RC_BAD_VALUE if dataSize is larger than 1024 TSS2_FAPI_RC_BAD_PATH if nvPath is not found. TSS2_FAPI_RC_NV_WRONG_TYPE if the NV is not an extendable index. TSS2_FAPI_RC_POLICY_UNKNOWN if the policy is unknown. TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending. TSS2_FAPI_RC_IO_ERROR if the data cannot be saved. TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters. TSS2_FAPI_RC_NO_TPM if FAPI was initialized in no-TPM-mode via its config file. TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization. TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found. TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned. TSS2_RC Fapi_NvExtend_Finish (FAPI_CONTEXT * context) Asynchronous finish function for Fapi_NvExtend This function should be called after a previous Fapi_NvExtend. Parameters context The FAPI_CONTEXT Return values TSS2_RC_SUCCESS if the function call was a success. TSS2_FAPI_RC_BAD_REFERENCE if context is NULL. TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected. TSS2_FAPI_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending. TSS2_FAPI_RC_IO_ERROR if the data cannot be saved. TSS2_FAPI_RC_MEMORY if the FAPI cannot allocate enough memory for internal operations or return parameters. TSS2_FAPI_RC_TRY_AGAIN if the asynchronous operation is not yet complete. Call this function again later. TSS2_FAPI_RC_BAD_PATH if a path is used in inappropriate context or contains illegal characters. TSS2_FAPI_RC_BAD_VALUE if an invalid value was passed into the function. TSS2_FAPI_RC_GENERAL_FAILURE if an internal error occurred. TSS2_FAPI_RC_PATH_NOT_FOUND if a FAPI object path was not found during authorization. TSS2_FAPI_RC_KEY_NOT_FOUND if a key was not found. TSS2_FAPI_RC_AUTHORIZATION_UNKNOWN if a required authorization callback is not set. TSS2_FAPI_RC_AUTHORIZATION_FAILED if the authorization attempt fails. TSS2_FAPI_RC_POLICY_UNKNOWN if policy search for a certain policy digest was not successful. TSS2_ESYS_RC_* possible error codes of ESAPI. TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
