Stefan Berger 9d8e6e36f6 tests: Check for permanent state file change due to TPM2_PCR_Read 
Extend a test case to check whether the permanent state files changes
when a TPM2_PCR_Read() is executed. The state file change would cause
timeouts inside VMs when an fsync() is used that fully synchronzies the
state of the TPM 2 with the data on disk. The issue has been resolved in
more recent versions of libtpms (master and branches). The updated
libtpms is required if fsync() for files and directories is to be enabled.

SWTPM - Software TPM Emulator
      David Safford safford@us.ibm.com
      Stefan Berger stefanb@us.ibm.com

The SWTPM package provides TPM emulators with different front-end interfaces
to libtpms. TPM emulators provide socket interfaces (TCP/IP and Unix) and
the Linux CUSE interface for the creation of multiple native /dev/vtpm* devices.

The SWTPM package also provides several tools for using the TPM emulator,
creating certificates for a TPM, and simulating the manufacturing of
a TPM by creating a TPM's EK and platform certificates etc. Please read 
the READMEs in the individual tool's directory under src/.

Please consult the Wiki for information about swtpm:
