Moreover, I need two hmac contexts in order to implement reset().

Can you explain how this works and what is needed? I don't remember much of TLS, so I have no idea what "reset" means here.

On plain HMAC the memory for the hashes was not that significant, but on umac that method is quite wasteful. I don't see a straightforward solution to that though, without a high level API.

Would it help to have a separate struct for the expanded key, and use that key with several per-message contexts? A bit like the split between struct gcm_key and struct gcm_ctx, in gcm.h? The same could be done also with hmac, if needed.
