Subject: [PATCH v15 0/3]] Add TDX Guest Attestation support
Date: Wed, 19 Oct 2022 21:58:25 -0700 [thread overview]
Message-ID: <20221020045828.2354731-1-sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
Hi All,
Intel's Trust Domain Extensions (TDX) protect guest VMs from malicious
hosts and some physical attacks. VM guest with TDX support is called
as a TDX Guest.
In TDX guest, attestation process is used to verify the TDX guest
trustworthiness to other entities before provisioning secrets to the
guest. For example, a key server may request for attestation before
releasing the encryption keys to mount the encrypted rootfs or
secondary drive.
This patch set adds attestation support for the TDX guest. Details
about the TDX attestation process and the steps involved are explained
in Documentation/x86/tdx.rst (added by patch 2/3).
Following are the details of the patch set:
Patch 1/3 -> Preparatory patch for adding attestation support.
Patch 2/3 -> Adds user interface driver to support attestation.
Patch 3/3 -> Adds selftest support for TDREPORT feature.
Commit log history is maintained in the individual patches.
Kuppuswamy Sathyanarayanan (3):
x86/tdx: Add a wrapper to get TDREPORT from the TDX Module
virt: Add TDX guest driver
selftests: tdx: Test TDX attestation GetReport support
