NAME

Fapi_WriteAuthorizeNv - Fapi_WriteAuthorizeNv

SYNOPSIS

Functions


TSS2_RC Fapi_WriteAuthorizeNv (FAPI_CONTEXT *context, char const *nvPath, char const *policyPath)
TSS2_RC Fapi_WriteAuthorizeNv_Async (FAPI_CONTEXT *context, char const *nvPath, char const *policyPath)
TSS2_RC Fapi_WriteAuthorizeNv_Finish (FAPI_CONTEXT *context)

Detailed Description

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

Function Documentation

Fapi_WriteAuthorizeNv (FAPI_CONTEXT * context, char const * nvPath, char const * policyPath)

One-Call function for Fapi_WriteAuthorizeNv

Write the policyDigest of a policy to an NV index so it can be used in policies containing PolicyAuthorizeNV elements.

Parameters

context The FAPI_CONTEXT
nvPath The path of the NV index
policyPath The path of the new policy

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or path is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if nvPath or policyPath does not map to a FAPI policy or NV index.
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_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_GENERAL_FAILURE if an internal error occurred.
TSS2_ESYS_RC_* possible error codes of ESAPI.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
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.

Fapi_WriteAuthorizeNv_Async (FAPI_CONTEXT * context, char const * nvPath, char const * policyPath)

Asynchronous function for Fapi_WriteAuthorizeNv

Write the policyDigest of a policy to an NV index so it can be used in policies containing PolicyAuthorizeNV elements.

Call Fapi_WriteAuthorizeNv_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
nvPath The path of the NV index
policyPath The path of the new policy

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context or path is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if nvPath or policyPath does not map to a FAPI policy or NV index.
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_BAD_VALUE if an invalid value was passed into the function.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.

Fapi_WriteAuthorizeNv_Finish (FAPI_CONTEXT * context)

Asynchronous finish function for Fapi_WriteAuthorizeNv

This function should be called after a previous Fapi_WriteAuthorizeNv_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_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_ESYS_RC_* possible error codes of ESAPI.
TSS2_FAPI_RC_BAD_PATH if the path is used in inappropriate context or contains illegal characters.
TSS2_FAPI_RC_NOT_PROVISIONED FAPI was not provisioned.
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.
