Subject: [PATCH 0/2] Update PCR read code

This patch set updates tpm2_pcr_read(), to build the PCR read command
buffer with tpm_buf functions, which offer protection against buffer
overflow.

It also removes duplicate code in tpm2_do_selftest(), and replaces it with
a call to tpm2_pcr_read().

The previous version of the patches can be found at the URLs:

https://sourceforge.net/p/tpmdd/mailman/message/35905413/
https://sourceforge.net/p/tpmdd/mailman/message/35905415/

The version number has not been incremented from 3 to 4, since this
is considered as a new patch set, not providing the same functionality
of the set the patches were originally part of.

Changelog

- PCR code changes are applied directly to tpm2_pcr_read()
- removed tpm2_pcr_read_in structure
- modified size of digest array in tpm2_pcr_read_out structure

Roberto Sassu (2):
  tpm: use tpm_buf functions in tpm2_pcr_read()
  tpm: use tpm2_pcr_read() in tpm2_do_selftest()
