Subject: [PATCH 00/12] ChaCha and BLAKE2s cleanups
This series is targeting libcrypto-next. It can also be retrieved from:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git chacha-blake2s-v1
This series consolidates how the ChaCha and BLAKE2s code is organized.
This is essentially the same change that I made to the other algorithms,
so this should be fairly boring by now.
These algorithms were the last two users of
lib/crypto/$(SRCARCH)/{Makefile,Kconfig}. So this series removes all
those files, finishing the transition to the centralized build process
(at least for the algorithms supported by lib/crypto/ so far).
This series also makes the arch-optimized BLAKE2s code start being
enabled by default, again following the pattern of the other algorithms.
Finally, it adds a KUnit test suite for BLAKE2s and deletes the older
blake2s-selftest.
Eric Biggers (12):
arm: configs: Remove obsolete assignments to CRYPTO_CHACHA20_NEON
crypto: chacha - register only "-lib" drivers
lib/crypto: chacha: Remove unused function chacha_is_arch_optimized()
lib/crypto: chacha: Rename chacha.c to chacha-block-generic.c
lib/crypto: chacha: Rename libchacha.c to chacha.c
lib/crypto: chacha: Consolidate into single module
lib/crypto: x86/blake2s: Reduce size of BLAKE2S_SIGMA2
lib/crypto: blake2s: Remove obsolete self-test
lib/crypto: blake2s: Always enable arch-optimized BLAKE2s code
lib/crypto: blake2s: Move generic code into blake2s.c
lib/crypto: blake2s: Consolidate into single C translation unit
lib/crypto: tests: Add KUnit tests for BLAKE2s
