| |
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
