[Qemu-devel] [PATCH v3 0/8] Provide support for the software TPM emulator

Posted by Amarnath Valluri 102 weeks ago
Briefly, Theses set of patches introduces:
  - new TPM backend driver to support software TPM emulators(swtpm(1)).
  - and few supported fixes/enhancements/cleanup to existing tpm backend code.

  The similar idea was initiated earliar(2) by Stefan Berger(CCed) with slightly
  different approach, using CUSE. As swtpm has excellent support for unix domain
  sockets, hence this implementation uses unix domain sockets to communicate
  with
  swtpm.

  When Qemu is configured with 'emulator' tpm backend, it spawns 'swtpm' and
  communicates its via Unix domain sockets.

  1) https://github.com/stefanberger/swtpm
  2) https://lists.nongnu.org/archive/html/qemu-devel/2016-01/msg00089.html

** Changes in V2:
- Made spawnning swtpm optional
- used QIOChannel instead of plain unix sockets
- incorporated other fixes pointed in v1 review

** Changes in v3:
- Addressed review comments made by Stefan Berger and Deniel P Berrange

Amarnath Valluri (8):
  tpm-backend: Remove unneeded member variable from backend class
  tpm-backend: Move thread handling inside TPMBackend
  tpm-backend: Initialize and free data members in it's own methods
  tpm-backend: Made few interface methods optional
  tmp backend: Add new api to read backend TpmInfo
  tpm-backend: Move realloc_buffer() implementation to base class
  tpm-passthrough: move reusable code to utils
  tpm: Added support for TPM emulator

[Qemu-devel] [PATCH v4 8/8] tpm: Added support for TPM emulator

Posted by Amarnath Valluri 102 weeks ago
This change introduces a new TPM backend driver that can communicate with
swtpm(software TPM emulator) using unix domain socket interface.

Swtpm uses two unix sockets, one for plain TPM commands and responses, and one
for out-of-band control messages.

The swtpm and associated tools can be found here:
    https://github.com/stefanberger/swtpm

The swtpm's control channel protocol specification can be found here:
    https://github.com/stefanberger/swtpm/wiki/Control-Channel-Specification

Usage:
    # setup TPM state directory
    mkdir /tmp/mytpm
    chown -R tss:root /tmp/mytpm
    /usr/bin/swtpm_setup --tpm-state /tmp/mytpm --createek

    # Ask qemu to use TPM emulator with given tpm state directory
    qemu-system-x86_64 \
        [...] \
        -tpmdev emulator,id=tpm0,tpmstatedir=/tmp/mytpm,logfile=/tmp/swtpm.log \
        -device tpm-tis,tpmdev=tpm0 \
        [...]
