...with the caveat that you cannot patch the stock OpenSSL in such a way
that any crypto operations are done by anything other than the FIPS
module, if you want to maintain the FIPS-ness of the systems you build
using it.  Formatting and processing of (including memory management
for) data that is encrypted or decrypted by the FIPS module is fair
game, which includes pretty much all of the security holes that have
happened to date in the OpenSSL library.
