Add tpm2_append_name() for appending to the handle area of the TPM command. When TPM_BUS_SECURITY is enabled and HMAC sessions are in use this adds the standard u32 handle to the buffer but additionally records the name of the object which must be used as part of the HMAC computation. The name of certain object types (volatile and permanent handles and NV indexes) is a hash of the public area of the object. Since this hash is not known ahead of time, it must be requested from the TPM using TPM2_ReadPublic() (which cannot be HMAC protected, but if an interposer lies about it, the HMAC check will fail and the problem will be detected).

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
