This patch set adds support for TPM spaces that provide an isolated
for transient objects and HMAC and policy sessions. A space is swapped
into TPM volatile memory only when it is used and swapped out after
the use.
There's a test script for trying out TPM spaces in
git://git.infradead.org/users/jjs/tpm2-scripts.git
A simple smoke test can be run by
sudo python -m unittest -v tpm2_smoke.SpaceTest
James Bottomley (3):
tpm: split out tpm-dev.c into tpm-dev.c and tpm-common-dev.c
tpm: expose spaces via a device link /dev/tpms<n>
tpm2: add session handle context saving and restoring to the space
code
Jarkko Sakkinen (3):
tpm: validate TPM 2.0 commands
tpm: export tpm2_flush_context_cmd
tpm: infrastructure for TPM spaces
