[edk2-devel] [PATCH v4 0/6] Ovmf: Disable the TPM2 platform hierarchy

[Stefan Berger]

This series imports code from the edk2-platforms project related to
changing the password of the TPM2 platform hierarchy and uses it to
disable 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

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

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