As swtpm has excellent support for unix domain\nsockets, hence this implementation uses unix domain sockets to communicate with\nswtpm.\n\nWhen Qemu is configured with 'emulator' tpm backend, it spawns 'swtpm' and\ncommunicates its via Unix domain sockets.\n\n1) https://github.com/stefanberger/swtpm\n2) https://lists.nongnu.org/archive/html/qemu-devel/2016-01/msg00089.html\n\n** Changes in V2:\n- Made spawnning swtpm optional\n- used QIOChannel instead of plain unix sockets\n- incorporated other fixes pointed in v1 review\n\n** Changes in v3:\n- Addressed review comments made by Stefan Berger and Deniel\nP Berrange\n\n** Changes in v4:\n- Moved realloc_buffer() to TIS model\n- Made TpmInfo related change backwards compatible.\n\n** Changes in v5:\n- updated Reviewed-By: tag to git commits\n- added migration blocker to TPM emulator backend\n\n** Changes in v6:\n- rebased agianst latest master\n- Address review comments maded by Stefan Berger\n\n** Changes in v7:\n- rebased agianst latest master\n- Rewritten emulater backend using chardev backend\n\nAmarnath Valluri (8):\n tpm-backend: Remove unneeded member variable from backend class\n tpm-backend: Move thread handling inside TPMBackend\n tpm-backend: Initialize and free data members in it's own methods\n tpm-backend: Made few interface methods optional\n tmp backend: Add new api to read backend TpmInfo\n tpm-backend: Move realloc_buffer() implementation to tpm-tis model\n tpm-passthrough: move reusable code to utils\n tpm: Added support for TPM emulator\n\n backends/tpm.c | 114 ++++---\n configure | 15 +-\n hmp.c | 12 +-\n hw/tpm/Makefile.objs | 1 +\n hw/tpm/tpm_emulator.c | 649 +++++++++++++++++++++++++++++++++++++++\n hw/tpm/tpm_ioctl.h | 246 +++++++++++++++\n hw/tpm/tpm_passthrough.c | 236 ++++----------\n hw/tpm/tpm_tis.c | 14 +-\n hw/tpm/tpm_util.c | 25 ++\n hw/tpm/tpm_util.h | 4 +\n include/sysemu/tpm_backend.h | 87 +++---\n include/sysemu/tpm_backend_int.h | 41 ---\n qapi/tpm.json | 21 +-\n qemu-options.hx | 22 +-\n tpm.c | 36 +--\n 15 files changed, 1173 insertions(+), 350 deletions(-)\n create mode 100644 hw/tpm/tpm_emulator.c\n create mode 100644 hw/tpm/tpm_ioctl.h\n delete mode 100644 include/sysemu/tpm_backend_int.h" }
