Subject[PATCH v6 0/3] Extend the vTPM proxy driver to pass locality
Date
The purpose of this series of patches is to enable the passing of the locality
a command is executing in to a recipient, i.e., TPM emulator. To enable this we
introduce vendor-specific TPM commands for TPM 1.2 and TPM 2 that the driver
sends to the TPM emulator.

v5->v6:
- Added patch 3/3.

v4->v5:
- introduce TPM_TRANSMIT_RAW to be able to call tpm_transmit without
recursing into requesting the locality.

v3->v4:
- addressed Jarkko's comments: largely a rewrite of the patches

v2->v3:
- addressed Jarkko's comments

v1->v2:
- fixed return value from function in patch 3/3


Stefan Berger (3):
tpm: Introduce flag TPM_TRANSMIT_RAW
tpm: vtpm_proxy: Implement request_locality function.
tpm: vtpm_proxy: Prevent userspace from sending driver command
