Subject: [PATCH v9 0/4] tpm: Preserve TPM measurement log across kexec (ppc64)
Date: Tue, 18 Apr 2023 09:44:05 -0400 [thread overview]
Message-ID: <20230418134409.177485-1-stefanb@linux.ibm.com> (raw)
The of-tree subsystem does not currently preserve the IBM vTPM 1.2 and
vTPM 2.0 measurement logs across a kexec on PowerVM and PowerKVM. This
series fixes this for the kexec_file_load() syscall using the flattened
device tree (fdt) to carry the TPM measurement log's buffer across kexec.

v9:
- 2/4: Rebased on 6.3-rc7: call tpm_read_log_memory_region if -ENODEV returned
v8:
- Added Jarkko's, Coiby's, and Rob's tags
- Rebase on v6.0-rc3 that absorbed 2 already upstreamed patches
v7:
- Added Nageswara's Tested-by tags
- Added back original comment to inline function and removed Jarkko's R-b tag
v6:
- Add __init to get_kexec_buffer as suggested by Jonathan
- Fixed issue detected by kernel test robot
v5:
- Rebased on 1 more patch that would otherwise create merge conflicts
v4:
- Rebased on 2 patches that would otherwise create merge conflicts;
posting these patches in this series with several tags removed so
krobot can test the series already
- Changes to individual patches documented in patch descripitons
v3:
- Moved TPM Open Firmware related function to drivers/char/tpm/eventlog/tpm_of.c
v2:
- rearranged patches
- fixed compilation issues for x86
