Subject: [PATCH 0/5] crypto: chacha20 - Alignment fixes
Date: Wed, 22 Nov 2017 11:51:34 -0800 [thread overview]
Message-ID: <20171122195139.121269-1-ebiggers3@gmail.com> (raw)
From: Eric Biggers <ebiggers@google.com>
This series fixes potentially unaligned memory accesses when loading the
initial state, key, and IV for ChaCha20, and when outputting each
keystream block.
It also removes the cra_alignmask from the generic and x86 ChaCha20
implementations, once it is no longer needed.
Eric Biggers (5):
crypto: chacha20 - Fix unaligned access when loading constants
crypto: chacha20 - Use unaligned access macros when loading key and IV
crypto: chacha20 - Remove cra_alignmask
crypto: x86/chacha20 - Remove cra_alignmask
crypto: chacha20 - Fix keystream alignment for chacha20_block()
