Stefan Berger 4b5654a19f swtpm: Disable fsync on file & dir due to TPM timeouts (issue #597) 
We cannot currently fsync on the TPM's state file and the dir since this
takes too long and commands in a VM may time out. The reason for this is
that the TPM 2 code occasionally writes the permanent state out even on
commands like TPM2_PCR_Extend that must not take a long time.

See explanation for this in the libtpms PR https://github.com/stefanberger/libtpms/pull/274 .

We will re-enable this feature in 'a while' once the updated libtpms
version has been made more widely available.

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:
