Whenever we encrypt the data we generate a new random IV and append a
tlv block with the IV to the byte stream. We mark the IV with different
tags depending on whether they are for the migration data or the (TPM)
data directly. All IVs are part of the HMAC and are added to it after
the data blob.
Adjust test cases that now return larger sizes of data. A constant
checksum over the data cannot be expected anymore, thus we have to remove
the verification of the checksum over the returned state (IV changes
every time).
The size of the blobs grow by 22 bytes, 6 for the tlv header, 16 bytes
for the IV (128 bit AES key).
Signed-off-by: Stefan Berger <stefanb@linux.vnet.ibm.com>
Prepend tag-length-value (tlv) headers in front of all data being stored in
the byte stream following the header. This lets us uniquely identify plain
data (= TPM state), encrypted data (= encrytped TPM state), migration data
(which is wrapped plain or encrytped TPM state), and an HMAC block to
validate the plain data.
We keep support for version 1 for reading the data but convert them to
version 2 when writing them out. This way we loose backwards compatibility
(downgrading of swtpm is not possible), but it allows us to extend the state
in the future by adding addition blocks with tlv headers.
Version 1 of the encryption was prepending the hash on the plaintext data
then encrypting all of it. This method is not so good. In version 2 we now
use Encrypt-then-MAC (EtM) where we encrypt the data and then calculate an
HMAC on the encrypted data.
Files written by the swtpm didn't have a header before. Now they also get a
header. This means that the state written into files and the state retrieved
using the API (swtpm_ioctl --save) have the same format, but still differ
in so far as the API wraps the data in a tlv header for migration, which the
files written out as state would never get.
Adapt a couple of test cases show file sizes and hashes have changed now.

Rather than writing to files directly and having to validate the state in
those files using TPMLIB_ValidatetState(), we now use the new
TPMLIB_SetState() call to set the TPM's state blobs. The advantage of this
call is that it doesn't overwrite state files and ends up leaving state in
files that the TPM cannot use. Instead, it validates the state immediately
when the blob is set and returns an error in case the state cannot be
accepted.
We need to adapt one test case that now gets a failure earlier than before.
Before the TPM_INIT failed, now setting the encrypted blob fails because it
cannot be decrypted and thus cannot be accepted by the TPM.

and adapt test cases accordingly.

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.

Remove the explicit saving of volatile state before saving the volatile
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.

Have test_resume_volatile create a temporary dir and copy test files to it
that may be modified during the test run.

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
bit in a given locality, also use the TPM_ResetEstablishmentBit
command for it in some test cases.

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
on a CUSE TPM that stores the state encrypted and on a CUSE TPM that
stores it non-encrypted.

Create uniqe names for the /dev/vtpm* so that tests can run in parallel.
Also separate the state directories of the TPMs into individual temporary
dirs.
