Subject: [PATCH v5 0/8] Ovmf: Disable the TPM2 platform hierarchy
Date: Wed, 1 Sep 2021 17:18:46 -0400 [thread overview]
Message-ID: <20210901211854.3795207-1-stefanb@linux.vnet.ibm.com> (raw)
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
