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))
Stepham Mueller pointed out that no authenc() ciphers are FIPS
approved and that ecb(des) also managed to get .fips_approved set.
The following patch removes fips_allowed for all those patches.
Again, Stephan pointed out that ansi_cprng will need to be taken off
the allowed list at the end of the year. This patch doesn't pre-empt
that.
