- CMD_STORE_VOLATILE
- CMD_HASH_DATA
Implement test cases.

Deactivate the checking for the certificate size since different
GnuTLS versions may create certificates of different sizes by adding
additional fields or other data to the cert.

Add support for the --tpmstate dir=<dir> command line parameter.
It will be used instead of the TPM_PATH, unless it is not set.
Adapt two test cases for the new parameter.

Add support for --pid file=<pidfile> command line parameter support.
The swtpm_cuse and swtpm now write their process IDs (pids) into
a file.

Support the read/write interface and POSIX API calls for transfer of
TPM state blobs.
Extend the swtpm_ioctl program to support this as well. Use the
environment variable SWTPM_IOCTL_BUFFERSIZE to set the size of the
buffer to use and enable the read/write interface in this (test)
program.

For being able to test the transfer of larger state blobs, extend the existing
test case with creating a large NVRAM location that becomes part of the permanent
state.

state blob to a file.

Add an ioctl that lets an application retrieve which keys are in use by the
TPM, i.e., file encryption or migration key
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
The migration key ensures that TPM state blobs, when retrieved using the
ioctl for getting state blobs, are always encrypted with this key.
When the state is later on loaded back into the TPM using the ioctl
to set the state blobs, the migration key is used to decrypt them.

Integrity protect the TPM state when it is written in entrypted form.
libtpms state (for TPM1.2) is also integrity protecting the blobs, but
we better determine the integrity of the decrypted data on the layer
above it.
Add a test case that ensures that swtpm-localca automatically
creates a signing key and issuer cert if none is available.

Rather than only using the ioctl to reset the TPM Establishment

Add new ioctls to get and set the 3 different types of state blobs
from and to the CUSE TPM. Add test cases for testing the new ioctl's

stores it non-encrypted.
