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
I don't see that branch in the swtpm tree:
[dgilbert@dgilbert-t530 swtpm]$ git branch -a
* (HEAD detached at origin/master)
master
remotes/origin/HEAD -> origin/master
remotes/origin/coverity_scan
remotes/origin/master
remotes/origin/master.next
remotes/origin/tpm2-preview
remotes/origin/tpm2-preview.v2
It's this one. Above is type.
Thanks for the reviews.

(I need to untangle my system libtpms from that specific version to get it to
build as
well)

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
