I'd be really happy to get a review on this patch - not so much what it is doing but rather the rational behind it - how is a tfm provider supposed to handle copying the last block of ciphertext into the request structure if the ciphertext size is less than a block?

Which algorithm is this? In general we disallow requests which are not a multiple of a block for block ciphers. Obviously this doesn't apply to stream ciphers such as ctr(aes), but in that case it doesn't really matter as you cannot chain such a request.
