Is that something that *can* be changed without breaking the disk format? SipHash is explicitly *not* designed to be secure as an unkeyed hash in the way that SHA-type algorithms are. What it's designed to do is provide second preimage resistance of its output, or a function (like modular reduction) of its output, against an attacker who doesn't know the secret seed. > Ack.

My big question is whether a single function call is okay or we need something inlinable. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
