Re: [PATCH v3 00/10] swtpm: Add support for profiles

Upcoming libtpms v0.10 and swtpm v0.10 will have TPM profile support that allows to restrict a TPM's provided set of crypto algorithms and commands and through which backwards compatibility and migration from newer versions of libtpms to older ones (up to libtpms v0.9) is supported. For the latter to work it is necessary that the user chooses the right ('null') profile. This series adds support for passing a profile choice to swtpm_setup by setting it in the domain XML using the <profile/> XML node. An optional attribute 'remove_disabled' can be set in this node and accepts two values: "check": test a few crypto algorithms (tdes, camellia, unpadded encryption, and others) for whether they are currently disabled due to FIPS mode on the host and remove these algorithms in the 'custom' profile if they are disabled; "fips-host": do not test but remove all the possibly disabled crypto algorithms (from list above) Also extend the documentation but point the user to swtpm and libtpms documentation for further details. Follow Deniel's suggestions there's now a PR for swtpm_setup to support searching for profiles though a configurable local directory, distro directory and if no profile could be found there (with appended ".json" suffix) it will fall back to try to use a built-in profile by the provided name: https://github.com/stefanberger/swtpm/pull/918 Stefan v3: - 2/10: Adjustments to due rebase - Applied Marc-André's R-b tags - 10/10: Read back profile name from swtpm and adjust it in emulator defs Stefan Berger (10): conf: Move TPM emulator parameters into own struct qemu: Pass virQEMUDriverConfig rather than some of its fields util: Add parsing support for swtpm_setup's cmdarg-profile capability conf: Define enum virDomainTPMProfileRemoveDisabled schema: Extend schema for TPM emulator profile node conf: Add support for profile parameter on TPM emulator in domain XML docs: Add documentation for the TPM backend profile node qemu: Extend swtpm_setup command line to set a profile by its name qemu: Move adding of keys to swtpm command line into own function qemu: Read the profile name after creation of TPM instance docs/formatdomain.rst | 30 +++ src/conf/domain_conf.c | 43 +++++ src/conf/domain_conf.h | 35 ++-- src/conf/domain_validate.c | 7 + src/conf/schemas/domaincommon.rng | 25 +++ src/conf/virconftypes.h | 2 + src/qemu/qemu_extdevice.c | 5 +- src/qemu/qemu_tpm.c | 310 ++++++++++++++++++++---------- src/qemu/qemu_tpm.h | 3 +- src/util/virtpm.c | 2 + src/util/virtpm.h | 2 + tests/testutilsqemu.c | 1 + 12 files changed, 355 insertions(+), 110 deletions(-)
