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 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 potentially disabled crypto
algorithms
Also extend the documentation but point the user to swtpm and libtpms
documentation for further details.
