[0/5] Updates to use IBM TSS C API rather than command line tools

Message

Ken Goldman Oct. 9, 2020, 3:48 p.m. UTC

This patch set replaces calls to command line tools with C code.  This
should be more stable and easier to maintain.  INSTALL instructions
are updated.

While the code is being touched, it changes the PCR handle from
a signed int to a uint32_t, removing the need for error checking.

Finally, it fixes an environment variable issue and some spelling
errors.

Ken Goldman (5):
   ima-evm-utils: Change env variable TPM_SERVER_TYPE for tpm_server
   ima-evm-utils: Change PCR iterator from int to uint32_t
   ima-evm-utils: Change tpm2_pcr_read() to use C code
   ima-evm-utils: Correct spelling errors
   ima-evm-utils: Expand the INSTALL instructions.
