NAME

Fapi_NvSetBits − Fapi_NvSetBits

SYNOPSIS

Functions

TSS2_RC Fapi_NvSetBits (FAPI_CONTEXT *context, char const *path, uint64_t bitmap)
TSS2_RC Fapi_NvSetBits_Async (FAPI_CONTEXT *context, char const *path, uint64_t bitmap)
TSS2_RC Fapi_NvSetBits_Finish (FAPI_CONTEXT *context)

Detailed Description

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

Function Documentation

Fapi_NvSetBits (FAPI_CONTEXT * context, char const * nvPath, uint64_t bitmap)
One-Call function for Fapi_NvSetBits

Sets bits in an NV index that was created as a bit field. Any number of bits from 0 to 64 may be SET.

Parameters

context The FAPI_CONTEXT
nvPath
The path to the NV index where bits are set
bitmap
The map of the bits to set

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE
if context or nvPath 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_WRONG_TYPE
if the NV index type is not TPM2_NT_COUNTER.
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_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_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_NvSetBits_Async (FAPI_CONTEXT * context, char const * nvPath, uint64_t bitmap)

Call Fapi_NvSetBits_Finish to finish the execution of this command.

Parameters

context The FAPI_CONTEXT
nvPath
The path to the NV index where bits are set
bitmap
The map of the bits to set

Return values

TSS2_RC_SUCCESS if the function call was a success.
TSS2_FAPI_RC_BAD_REFERENCE
if context or nvPath 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_WRONG_TYPE
if the NV index type is not TPM2_NT_COUNTER.
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_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_NvSetBits_Finish (FAPI_CONTEXT * context)
Asynchronous finish function for Fapi_NnSetBits

This function should be called after a previous Fapi_NvSetBIts_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.

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.
