Detailed Description

ESAPI function to invoke the TPM2_LoadExternal command either as a one-call or in an asynchronous manner.

Function Documentation

TSS2_RC Esys_Load_Finish (ESYS_CONTEXT * esysContext, ESYS_TR * objectHandle)

Asynchronous finish function for TPM2_Load

This function returns the results of a TPM2_Load command invoked via Esys_Load_Finish. All non-simple output parameters are allocated by the function's implementation. NULL can be passed for every output parameter if the value is not required.

Parameters:

esysContext The ESYS_CONTEXT.
objectHandle ESYS_TR handle of ESYS resource for TPM2_HANDLE.

Return values:

TSS2_RC_SUCCESS on success
ESYS_RC_SUCCESS if the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_ESYS_RC_TRY_AGAIN if the timeout counter expires before the TPM response is received.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response length, and response code.
TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.

One-Call function for TPM2_LoadExternal

This function invokes the TPM2_LoadExternal command in a one-call variant. This means the function will block until the TPM response is available. All input parameters are const. The memory for non-simple output parameters is allocated by the function implementation.

Parameters:

esysContext The ESYS_CONTEXT.
shandle1 First session handle.
shandle2 Second session handle.
shandle3 Third session handle.
inPrivate The sensitive portion of the object (optional).
inPublic The public portion of the object.
hierarchy Hierarchy with which the object area is associated.
objectHandle ESYS_TR handle of ESYS resource for TPM2_HANDLE.

Return values:

TSS2_RC_SUCCESS if the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_ESYS_RC_BAD_SEQUENCE if the context has an asynchronous operation already pending.
TSS2_ESYS_RC_INSUFFICIENT_RESPONSE if the TPM's response does not at least contain the tag, response length, and response code.
TSS2_ESYS_RC_MALFORMED_RESPONSE if the TPM's response is corrupted.
TSS2_ESYS_RC_RSP_AUTH_FAILED if the response HMAC from the TPM did not verify.
TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.

Asynchronous function for TPM2_LoadExternal

This function invokes the TPM2_LoadExternal command in a asynchronous variant. This means the function will return as soon as the command has been sent downwards the stack to the TPM. All input parameters are const. In order to retrieve the TPM's response call Esys_LoadExternal_Finish.

Parameters:

esysContext The ESYS_CONTEXT.
shandle1 First session handle.
shandle2 Second session handle.
shandle3 Third session handle.
inPrivate The sensitive portion of the object (optional).
inPublic The public portion of the object.
hierarchy Hierarchy with which the object area is associated.

Return values:

ESYS_RC_SUCCESS if the function call was a success.
TSS2_ESYS_RC_BAD_REFERENCE if the esysContext or required input pointers or required output handle references are NULL.
TSS2_ESYS_RC_BAD_CONTEXT if esysContext corruption is detected.
TSS2_ESYS_RC_MEMORY if the ESAPI cannot allocate enough memory for internal operations or return parameters.
TSS2_RCs produced by lower layers of the software stack may be returned to the caller unaltered unless handled internally.
TSS2_ESYS_RC_MULTIPLE_DECRYPT_SESSIONS if more than one session has the 'decrypt' attribute bit set.
TSS2_ESYS_RC_MULTIPLE_ENCRYPT_SESSIONS if more than one session has the 'encrypt' attribute bit set.
