Testing and Development

Testing can be done on emulated TPM, on ubuntu you can emulate a TPM by first installing swtpm and (optionally for debugging) tpm2-tools:

sudo apt-get install swtpm tpm2-tools

For the emulation, first load the tpm_vtpm_proxy:

sudo modprobe tpm_vtpm_proxy

Next install and compile the linux-vtpm-tests, vtpmctrl is required to glue swtpm and tpm_vtpm_proxy and created TPM char devices:

git clone https://github.com/stefanberger/linux-vtpm-tests.git
cd linux-vtpm-tests
./bootstrap.sh
./configure
make

Finally emulate the TPM:

vtpmctrl --tpm2 --spawn /bin/swtpm chardev --tpm2 --fd %fd --tpmstate dir=/tmp --flags not-need-init --locality allow-set-locality

You should see the TPM device available:

~$ ls /dev/tpm*
/dev/tpm0  /dev/tpmrm0

now you can simply run the tpmea tests by invoking go test -v.
