Hello All,
"Make fips=1 work on 4.1", they said, wittily, "it'll be easy."
I suppose it wasn't that complicated, although I seem to be unearthing
other problems as I go along. The first problem was dracut (and I owe
an upstream patch for that) and the second problem was tcrypt.
The tcrypt module was failing on authenc ciphers that wrap non-FIPS
ciphers and hashes. These ones in fact:
authenc(hmac(md5),ecb(cipher_null))
authenc(hmac(sha1),cbc(des))
authenc(hmac(sha1),ecb(cipher_null))
authenc(hmac(sha224),cbc(des))
authenc(hmac(sha256),cbc(des))
authenc(hmac(sha384),cbc(des))
authenc(hmac(sha512),cbc(des))
I'm fairly sure that wrapping des, cipher_null and md5 in authenc
shouldn't make them fips-allowed so the following patch simply removes
that.
Interestingly, some of these just failed outright and others just sat
there chewing CPU time. I think that's just a curiousity though,
rather than a problem.
