When testing downgrading from libtpms 0.8 to 0.7 (which is not
possible), the error message which is reported is:
libtpms/tpm2: Unexpect value for MAX_RSA_KEY_BITS; its value 3072 is
not = 2048; (version: 2).
codespell (https://github.com/codespell-project/codespell) reports a
misspelling for "Unexpect", which should be "Unexpected". As the project
contains many more misspellings in comments, error messages and
documentation, fix all misspellings reported by codespell.

|
|
TPMLIB_ValidateState - Validate the state blobs of the TPM
|
|
|
|
=head1 LIBRARY
|
|
|
|
TPM library (libtpms, -ltpms)
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<#include <libtpms/tpm_library.h>>
|
|
|
|
B<uint32_t TPMLIB_ValidateState(TPMLIB_StateType st,
|
|
unsigned int flags);
|
|
>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<TPMLIB_ValidateState()> function allows to validate the
|
|
state blobs that the TPM would read upon B<TPMLIB_MainInit()> or
|
|
once the TPM_Startup command has been sent to it.
|
|
|
|
This function is useful for TPM state migration between possibly
|
|
different version of libtpms. Here the target libtpms needs to be
|
|
able to determine whether it can support the version of blobs that were
|
|
migrated and if this is not the case, the caller can refuse the
|
|
migration.
|
|
|
|
The B<tpmlib_state> parameter can be a logical 'or' of one or
|
|
multiple of of the following: B<TPMLIB_STATE_PERMANENT>,
|
|
B<TPMLIB_STATE_VOLATILE>, or B<TPMLIB_STATE_SAVE_STATE>.
|
|
The B<flags> parameter is currently not used and should be set to 0.
|
|
|
|
The first state blob that should be loaded is the permanent state,
|
|
since for example the volatile state requires it to be available
|
|
for validation.
|
|
|
|
This function should be called before B<TPMLIB_MainInit()> is invoked.
