Subject[PATCH v3 0/7] in-kernel resource manager
Date
This patch set adds support for TPM spaces that provide an isolated
execution context 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 suite can be run by

sudo python -m unittest -v tpm2_smoke.SpaceTest

v3:
* Reverted back to /dev/tpmrm0 that was actually James' original
proposal. It's the most pragmatic choice as it cannot be mixed
with other TPM 2.0 and kernel idioms easily.

v2:
* Substitute virtual handle in ContextSave.
* Substitute virtual handles in GetCapability.
* Validate that the real response length and the one reported in the
header match in tpm_transmit().


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/tpmrm<n>
tpm2: add session handle context saving and restoring to the space
code

Jarkko Sakkinen (4):
tpm: move length validation to tpm_transmit()
tpm: validate TPM 2.0 commands
tpm: export tpm2_flush_context_cmd
tpm: infrastructure for TPM spaces
