[PATCH v2 0/7] in-kernel resource manager

[Jarkko Sakkinen]

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   

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/tpms<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
