Pardon the top-post.  Paul Moore suggested this mailing list as the best
place to ask the following.

Thanks,

Not sure if this is the most appropriate list for the topic, but I'm sure
enough actual AH/ESP implementors hang out here.

I've noticed at least one other platform doesn't do SHA-2 per RFC 4868
(half-sized hash truncation), and instead truncates the SHA-2 hashes to
96-bits like MD5 and SHA1.

Is this just me, or is there an unfixed kernel problem in other platforms'
AH/ESP code?

Thanks,
Dan
