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. Stefan 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 Palmer Dabbelt (1): drivers: of: kexec ima: Support 32-bit platforms Stefan Berger (3): tpm: of: Make of-tree specific function commonly available of: kexec: Refactor IMA buffer related functions to make them reusable tpm/kexec: Duplicate TPM measurement log in of-tree for kexec drivers/char/tpm/eventlog/of.c | 31 +-- drivers/of/kexec.c | 336 ++++++++++++++++++++++++++++----- include/linux/kexec.h | 6 + include/linux/of.h | 9 +- include/linux/tpm.h | 36 ++++ kernel/kexec_file.c | 6 + 6 files changed, 346 insertions(+), 78 deletions(-) base-commit: b90cb1053190353cc30f0fef0ef1f378ccc063c5 -- 2.35.1 _______________________________________________ kexec mailing list kexec@lists.infradead.org http://lists.infradead.org/mailman/listinfo/kexec
