This series of patches implements support for migrating the state of the external 'swtpm' TPM emulator as well as that of the TIS interface.
For testing of TPM 2 (migration) please use the following git repos and branches: libtpms: - repo: https://github.com/stefanberger/libtpms - branch: tpm2-preview.rev146.v2 swtpm: - repo: https://github.com/stefanberger/swtpm - branch: tpm2-preview.rev146.v2 Regards, Stefan Changes: v4->v5: - followed Marc-André's and Alan's comments where possible; some comments were not addressed and reasons posted to mailing list - converted debug statements to tracing - qemu_chr_fe_read_all does not return errno, so displaying expected versus received number of bytes rather than strerror(errno) - added test cases - added documentation for migration to docs/spec/tpm.txt v3->v4: - dropped the size limit enforcement on blobs received from the swtpm - the .post_load migration function requires errno's to be returned. -> some of the functions have been converted to return a better errno Stefan Berger (4): tpm: extend TPM emulator with state migration support tpm: extend TPM TIS with state migration support docs: tpm: add VM save/restore example and troubleshooting guide tpm: Add test cases that uses the external swtpm with CRB interface docs/specs/tpm.txt | 106 +++++++++++++++ hw/tpm/tpm_emulator.c | 318 +++++++++++++++++++++++++++++++++++++++++++-- hw/tpm/tpm_tis.c | 52 +++++++- hw/tpm/trace-events | 9 +- tests/Makefile.include | 3 + tests/tpm-crb-swtpm-test.c | 244 ++++++++++++++++++++++++++++++++++ tests/tpm-util.c | 143 ++++++++++++++++++++ tests/tpm-util.h | 36 +++++ 8 files changed, 897 insertions(+), 14 deletions(-) create mode 100644 tests/tpm-crb-swtpm-test.c create mode 100644 tests/tpm-util.c create mode 100644 tests/tpm-util.h -- 2.5.5
