Subject: [PATCH v3 01/29] crypto: chacha - move existing library code into lib/crypto
Date: Mon, 7 Oct 2019 18:45:42 +0200 [thread overview]
Message-ID: <20191007164610.6881-2-ard.biesheuvel@linaro.org> (raw)
In-Reply-To: <20191007164610.6881-1-ard.biesheuvel@linaro.org>
Currently, our generic ChaCha implementation consists of a permute
function in lib/chacha.c that operates on the 64-byte ChaCha state
directly [and which is always included into the core kernel since it
is used by the /dev/random driver], and the crypto API plumbing to
expose it as a skcipher.
In order to support in-kernel users that need the ChaCha streamcipher
but have no need [or tolerance] for going through the abstractions of
the crypto API, let's expose the streamcipher bits via a library API
as well, in a way that permits the implementation to be superseded by
an architecture specific one if provided.
So move the streamcipher code into a separate module in lib/crypto,
and expose the init() and crypt() routines to users of the library.
And while at it, tidy up lib/crypto/Makefile a bit so we are ready for
some new arrivals.
