NAME¶
Fapi_NvWrite - Fapi_NvWrite
SYNOPSIS¶
Functions¶
TSS2_RC Fapi_NvWrite (FAPI_CONTEXT *context, char
const *path, uint8_t const *data, size_t size)
TSS2_RC Fapi_NvWrite_Async (FAPI_CONTEXT *context, char const
*path, uint8_t const *data, size_t size)
TSS2_RC Fapi_NvWrite_Finish (FAPI_CONTEXT *context)
Detailed Description¶
FAPI functions to invoke NvWrite either as one-call or in an asynchronous manner.
Function Documentation¶
Fapi_NvWrite (FAPI_CONTEXT * context, char const * nvPath, uint8_t const * data, size_t size)¶
One-Call function for Fapi_NvWrite
Writes data to a 'regular' (not pin, extend or counter) NV index.
Parameters
nvPath The path of the NV index to write
data The data to write to the NV index
size The size of data in bytes
Return values
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_EXCEEDED if the NV is not large enough for the data to be written.
TSS2_FAPI_RC_NV_WRONG_TYPE if the NV index is not a 'regular' one.
TSS2_FAPI_RC_NV_NOT_WRITEABLE if the NV is not a writeable 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_TRY_AGAIN if an I/O operation is not finished yet and this function needs to be called again.
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_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.
Fapi_NvWrite_Async (FAPI_CONTEXT * context, char const * nvPath, uint8_t const * data, size_t size)¶
Asynchronous function for Fapi_NvWrite
Writes data to a 'regular' (not pin, extend or counter) NV index.
Call Fapi_NvWrite_Finish to finish the execution of this command.
Parameters
nvPath The path of the NV index to write
data The data to write to the NV index
size The size of data in bytes
Return values
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_EXCEEDED if the NV is not large enough for the data to be written.
TSS2_FAPI_RC_NV_WRONG_TYPE if the NV index is not a 'regular' one.
TSS2_FAPI_RC_NV_NOT_WRITEABLE if the NV is not a writeable 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.
Fapi_NvWrite_Finish (FAPI_CONTEXT * context)¶
Asynchronous finish function for Fapi_NvWrite
This function should be called after a previous Fapi_NvWrite.
Parameters
Return values
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_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_BAD_PATH if a path is used in inappropriate context or contains illegal characters.
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.
