Subject: [RFC PATCH 0/3] reworked ccm(aes) using blkcipher walk API
Date: Tue, 25 Feb 2014 13:57:49 +0100	[thread overview]
Message-ID: <1393333072-15310-1-git-send-email-ard.biesheuvel@linaro.org> (raw)

As suggested by Herbert, this is another approach to using the blkcipher walk
API from a context where no [a]blkcipher transform instance exists.

I have copied some data that is retrieved from the transform into the
blkcipher_walk struct, and added alternative blkcipher init and walk functions
that allow these data member (iv size, alignmask, etc) to be supplied directly.

Suggestions for better names than blkcipher_walk_init_raw and
blkcipher_walk_virt_raw are highly appreciated.


Ard Biesheuvel (3):
  crypto: remove direct blkcipher_walk dependency on transform
  crypto: allow blkcipher walks with no associated blkcipher transform
  arm64: add support for AES in CCM mode using Crypto Extensions
