Almost true. If it wasn't banned by the FIPS security policy, checking in
the uncompressed tarball could be used to efficiently manage and track new
upstream releases of the tarball and to document which exact upstream FIPS
cannister source code (and hence corresponding validation date) was
incorporated into which product version (an aspect of FIPS compliance which
someone might want to audit
But alas, as you clarify below, this is not permitted by the OpenSSL FIPS
security policy directly incorporated into the validation.
The slightly less efficient idea of putting the compressed tarball into
the configuration control repository (which in this case *is* tracking the
build configuration, not the code versions) is probably (I am not sure)
againstthe policy that the tarball must be taken "securely" from the
physical CD mailed out by the OpenSSL foundation.
So the thing that can probably be put into a repository is the binary
FIPSCannister.o file along with copies of any documents certifying how,
where, from what and by whom said FIPS cannister was built.
Of cause, one could, purely for debugging/documentation purposes, include
a copy of the FIPS Cannister source code in the repository, one just
cannot compile anything releasable from it.
