SYNOPSIS

Functions


TSS2_RC Fapi_AuthorizePolicy (FAPI_CONTEXT *context, char const *policyPath, char const *keyPath, uint8_t const *policyRef, size_t policyRefSize)
TSS2_RC Fapi_AuthorizePolicy_Async (FAPI_CONTEXT *context, char const *policyPath, char const *keyPath, uint8_t const *policyRef, size_t policyRefSize)
TSS2_RC Fapi_AuthorizePolicy_Finish (FAPI_CONTEXT *context)

Detailed Description

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

Function Documentation

TSS2_RC Fapi_AuthorizePolicy (FAPI_CONTEXT * context, char const * policyPath, char const * keyPath, uint8_t const * policyRef, size_t policyRefSize)

One-Call function for Fapi_AuthorizePolicy

If a current policy happens to be a PolicyAuthorize, then for it to be used, the user must first satisfy a policy authorized by a having been signed (and made into a ticket) by an authorized party.

Parameters

context The FAPI context
policyPath The path to the policy file
keyPath The path to the signing key
policyRef A byte buffer that is included in the signature. May be NULL
policyRefSize The size of policyRef. Must be 0 if policyRef is NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context, policyPath or keyPath is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if policyPath or keyPath does not map to a FAPI policy or key object.
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_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.

TSS2_RC Fapi_AuthorizePolicy_Async (FAPI_CONTEXT * context, char const * policyPath, char const * keyPath, uint8_t const * policyRef, size_t policyRefSize)

Asynchronous function for Fapi_AuthorizePolicy

If a current policy happens to be a PolicyAuthorize, then for it to be used, the user must first satisfy a policy authorized by a having been signed (and made into a ticket) by an authorized party.

Call Fapi_AuthorizePolicy_Finish to finish the execution of this command.

Parameters

context The FAPI context
policyPath The path to the policy file
keyPath The path to the signing key
policyRef A byte buffer that is included in the signature. May be NULL
policyRefSize The size of policyRef. Must be 0 if policyRef is NULL

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE if context, policyPath or keyPath is NULL.
TSS2_FAPI_RC_BAD_CONTEXT if context corruption is detected.
TSS2_FAPI_RC_BAD_PATH if policyPath or keyPath does not map to a FAPI policy or key object.
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_RC Fapi_AuthorizePolicy_Finish (FAPI_CONTEXT * context)

Asynchronous finish function for Fapi_AuthorizePolicy

This function should be called after a previous Fapi_AuthorizePolicy_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_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_BAD_VALUE if an invalid value was passed into the function.
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.
