[edk2-devel] [PATCH v5 0/8] Ovmf: Disable the TPM2 platform hierarchy

[Stefan Berger]

This series imports code from the edk2-platforms project related to
disabling the TPM2 platform hierarchy in Ovmf and ArmVirtPkg. It
addresses the Ovmf aspects of the following bugs:

https://bugzilla.tianocore.org/show_bug.cgi?id=3510
https://bugzilla.tianocore.org/show_bug.cgi?id=3499

I have patched the .dsc files and successfully test-built with most of
them. Some I could not build because they failed for other reasons
unrelated to this series.

I tested the changes with QEMU on x86 following the build of
ArmVirtQemu.dsc and OvmfPkgX64.dsc.

The disablement of the platform hierarchy is done after possibly
handling PPI. Following TPM 2 logs on Arm, only PCR extensions are
following afterwards until GRUB takes over.

Neither one of the following commands should work anymore on first
try:

With IBM tss2 tools:
tsshierarchychangeauth -hi p -pwdn newpass

With Intel tss2 tools:
tpm2_changeauth -c platform newpass

Regards,
  Stefan

v5:
 - Modified patch 1 copies the code from edk2-platforms
 - Modified patch 2 fixes bugs in the code
 - Modified patch 4 introduces required PCD

v4:
 - Fixed and simplified code imported from edk2-platforms

v3:
 - Referencing Null implementation on Bhyve and Xen platforms
 - Add support in ArmVirtPkg
