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.
