crypto: arm64/sm4-ce - rename to sm4-ce-cipher The subsequent patches of the series will have an implementation of SM4-ECB/CBC/CFB/CTR accelerated by the CE instruction set, which conflicts with the current module name. In order to keep the naming rules of the AES algorithm consistent, the sm4-ce algorithm is renamed to sm4-ce-cipher. In addition, the speed of sm4-ce-cipher is better than that of SM4 NEON. By the way, the priority of the algorithm is adjusted to 300, which is also to leave room for the priority of SM4 NEON.

obj-$(CONFIG_CRYPTO_AES_ARM64_CE) += aes-ce-cipher.o
crypto: arm64/aes-ce-cipher - move assembler code to .S file Most crypto drivers involving kernel mode NEON take care to put the code that actually touches the NEON register file in a separate compilation unit, to prevent the compiler from reordering code that preserves or restores the NEON context with code that may corrupt it. This is necessary because we currently have no way to express the restrictions imposed upon use of the NEON in kernel mode in a way that the compiler understands. However, in the case of aes-ce-cipher, it did not seem unreasonable to deviate from this rule, given how it does not seem possible for the compiler to reorder cross object function calls with asm blocks whose in- and output constraints reflect that it reads from and writes to memory. Now that LTO is being proposed for the arm64 kernel, it is time to revisit this. The link time optimization may replace the function calls to kernel_neon_begin() and kernel_neon_end() with instantiations of the IR that make up its implementation, allowing further reordering with the asm block. So let's clean this up, and move the asm() blocks into a separate .S file.

All S-box substitutions are performed in parallel, leveraging the wide range of ARMv8's tbl/tbx instructions, and the huge NEON register file, which can comfortably hold the entire S-box and still have room to spare for doing the actual computations.

The version in this patch was taken from OpenSSL commit 32bbb62ea634 ("sha/asm/sha512-armv8.pl: fix big-endian support in __KERNEL__ case.") * The core SHA algorithm is fundamentally sequential, but there is a secondary transformation involved, called the schedule update, which can be performed independently. The NEON version of SHA-224/SHA-256 only implements this part of the algorithm using NEON instructions, the sequential part is always done using scalar instructions.

crypto: arm64/aes - add scalar implementation This adds a scalar implementation of AES, based on the precomputed tables that are exposed by the generic AES code. Since rotates are cheap on arm64, this implementation only uses the 4 core tables (of 1 KB each), and avoids the prerotated ones, reducing the D-cache footprint by 75%. On Cortex-A57, this code manages 13.0 cycles per byte, which is ~34% faster than the generic C code. (Note that this is still >13x slower than the code that uses the optional ARMv8 Crypto Extensions, which manages <1 cycles per byte.)

crypto: arm64/aes - reimplement bit-sliced ARM/NEON implementation for arm64 This is a reimplementation of the NEON version of the bit-sliced AES algorithm. This code is heavily based on Andy Polyakov's OpenSSL version for ARM, which is also available in the kernel. This is an alternative for the existing NEON implementation for arm64 authored by me, which suffers from poor performance due to its reliance on the pathologically slow four register variant of the tbl/tbx NEON instruction. This version is about ~30% (*) faster than the generic C code, but only in cases where the input can be 8x interleaved (this is a fundamental property of bit slicing). For this reason, only the chaining modes ECB, XTS and CTR are implemented. (The significance of ECB is that it could potentially be used by other chaining modes) * Measured on Cortex-A57. Note that this is still an order of magnitude slower than the implementations that use the dedicated AES instructions introduced in ARMv8, but those are part of an optional extension, and so it is good to have a fallback.

arm64/crypto: AES-ECB/CBC/CTR/XTS using ARMv8 NEON and Crypto Extensions This adds ARMv8 implementations of AES in ECB, CBC, CTR and XTS modes, both for ARMv8 with Crypto Extensions and for plain ARMv8 NEON. The Crypto Extensions version can only run on ARMv8 implementations that have support for these optional extensions. The plain NEON version is a table based yet time invariant implementation. All S-box substitutions are performed in parallel, leveraging the wide range of ARMv8's tbl/tbx instructions, and the huge NEON register file, which can comfortably hold the entire S-box and still have room to spare for doing the actual computations. The key expansion routines were borrowed from aes_generic. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Acked-by: Herbert Xu <herbert@gondor.apana.org.au>
