ARM: add support for bit sliced AES using NEON instructions Bit sliced AES gives around 45% speedup on Cortex-A15 for encryption and around 25% for decryption. This implementation of the AES algorithm does not rely on any lookup tables so it is believed to be invulnerable to cache timing attacks. This algorithm processes up to 8 blocks in parallel in constant time. This means that it is not usable by chaining modes that are strictly sequential in nature, such as CBC encryption. CBC decryption, however, can benefit from this implementation and runs about 25% faster. The other chaining modes implemented in this module, XTS and CTR, can execute fully in parallel in both directions. The core code has been adopted from the OpenSSL project (in collaboration with the original author, on cc). For ease of maintenance, this version is identical to the upstream OpenSSL code, i.e., all modifications that were required to make it suitable for inclusion into the kernel have been made upstream. The original can be found here: http://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=6f6a6130 Note to integrators: While this implementation is significantly faster than the existing table based ones (generic or ARM asm), especially in CTR mode, the effects on power efficiency are unclear as of yet. This code does fundamentally more work, by calculating values that the table based code obtains by a simple lookup; only by doing all of that work in a SIMD fashion, it manages to perform better.

Unfortunately, I could not come up with a way to make the Kconfig symbol depend on the binutils version, which would be the nicest solution.

crypto: arm/crc32 - accelerated support based on x86 SSE implementation This is a combination of the the Intel algorithm implemented using SSE and PCLMULQDQ instructions from arch/x86/crypto/crc32-pclmul_asm.S, and the new CRC32 extensions introduced for both 32-bit and 64-bit ARM in version 8 of the architecture. Two versions of the above combo are provided, one for CRC32 and one for CRC32C. The PMULL/NEON algorithm is faster, but operates on blocks of at least 64 bytes, and on multiples of 16 bytes only. For the remaining input, or for all input on systems that lack the PMULL 64x64->128 instructions, the CRC32 instructions will be used.

ARM: add support for bit sliced AES using NEON instructions Bit sliced AES gives around 45% speedup on Cortex-A15 for encryption and around 25% for decryption. This implementation of the AES algorithm does not rely on any lookup tables so it is believed to be invulnerable to cache timing attacks. This algorithm processes up to 8 blocks in parallel in constant time. This means that it is not usable by chaining modes that are strictly sequential in nature, such as CBC encryption. CBC decryption, however, can benefit from this implementation and runs about 25% faster. The other chaining modes implemented in this module, XTS and CTR, can execute fully in parallel in both directions. The core code has been adopted from the OpenSSL project (in collaboration with the original author, on cc). For ease of maintenance, this version is identical to the upstream OpenSSL code, i.e., all modifications that were required to make it suitable for inclusion into the kernel have been made upstream. The original can be found here: http://git.openssl.org/gitweb/?p=openssl.git;a=commit;h=6f6a6130 Note to integrators: While this implementation is significantly faster than the existing table based ones (generic or ARM asm), especially in CTR mode, the effects on power efficiency are unclear as of yet. This code does fundamentally more work, by calculating values that the table based code obtains by a simple lookup; only by doing all of that work in a SIMD fashion, it manages to perform better.

crypto: arm/sha512 - accelerated SHA-512 using ARM generic ASM and NEON This replaces the SHA-512 NEON module with the faster and more versatile implementation from the OpenSSL project. It consists of both a NEON and a generic ASM version of the core SHA-512 transform, where the NEON version reverts to the ASM version when invoked in non-process context. This patch is based on the OpenSSL upstream version b1a5d1c65208 of sha512-armv4.pl, which can be found here: https://git.openssl.org/gitweb/?p=openssl.git;h=b1a5d1c65208 Performance relative to the generic implementation (measured using tcrypt.ko mode=306 sec=1 running on a Cortex-A57 under KVM): input size block size asm neon old neon 16 16 1.39 2.54 2.21 64 16 1.32 2.33 2.09 64 64 1.38 2.53 2.19 256 16 1.31 2.28 2.06 256 64 1.38 2.54 2.25 256 256 1.40 2.77 2.39 1024 16 1.29 2.22 2.01 1024 256 1.40 2.82 2.45 1024 1024 1.41 2.93 2.53 2048 16 1.33 2.21 2.00 2048 256 1.40 2.84 2.46 2048 1024 1.41 2.96 2.55 2048 2048 1.41 2.98 2.56 4096 16 1.34 2.20 1.99 4096 256 1.40 2.84 2.46 4096 1024 1.41 2.97 2.56 4096 4096 1.41 3.01 2.58 8192 16 1.34 2.19 1.99 8192 256 1.40 2.85 2.47 8192 1024 1.41 2.98 2.56 8192 4096 1.41 2.71 2.59 8192 8192 1.51 3.51 2.69 Acked-by: Jussi Kivilinna <jussi.kivilinna@iki.fi> Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
