NAME

Fapi_PcrExtend − Fapi_PcrExtend

SYNOPSIS

Functions

TSS2_RC Fapi_PcrExtend (FAPI_CONTEXT *context, uint32_t pcr, uint8_t const *data, size_t dataSize, char const *logData)
TSS2_RC Fapi_PcrExtend_Async (FAPI_CONTEXT *context, uint32_t pcr, uint8_t const *data, size_t dataSize, char const *logData)

Detailed Description

FAPI functions to invoke PcrExtend either as one-call or in an asynchronous manner.

Function Documentation

Fapi_PcrExtend (FAPI_CONTEXT * context, uint32_t pcr, uint8_t const * data, size_t dataSize, char const * logData)
One-Call function for Fapi_PcrExtend

Performs an extend operation on a given PCR.

Parameters

context The FAPI_CONTEXT
pcr The PCR to extend
data The data that is to be extended on the PCR
dataSize The size of data in bytes
logData A JSON representation of data to be written to the PCR’s event log. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or data is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_NO_PCR if no such PCR exists on this TPM.
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_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again.
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_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_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.
TSS2_FAPI_RC_BAD_PATH if the path is used in inappropriate context or contains illegal characters.

Fapi_PcrExtend_Async (FAPI_CONTEXT * context, uint32_t pcr, uint8_t const * data, size_t dataSize, char const * logData)
Asynchronous function for Fapi_PcrExtend

Performs an extend operation on a given PCR.

Call Fapi_PcrExtend_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
pcr The PCR to extend
data The data that is to be extended on the PCR
dataSize The size of data in bytes
logData A JSON representation of data to be written to the PCR’s event log. May be NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or data is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_NO_PCR if no such PCR exists on this TPM.
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_BAD_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_NO_TPM if FAPI was initialized in no-TPM-mode via its config file.
TSS2_ESYS_RC_* possible error codes of ESAPI.

Fapi_PcrExtend_Finish (FAPI_CONTEXT * context)
Asynchronous finish function for Fapi_PcrExtend

This function should be called after a previous Fapi_PcrExtend_Async.

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_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_BAD_VALUE if an invalid value was passed into the function.
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_FAPI_RC_POLICY_UNKNOWN if policy search for a certain policy digest was not successful.
