#63576 — Bug#924456: linux-image-4.19.0-2-arm64: please enable accelerated arm64 crypto drivers

Package: src:linux
Version: 4.19.16-1
Severity: normal

Dear Maintainer,

Please consider enabling the following Kconfig options for arm64 kernels

CONFIG_CRYPTO_SHA256_ARM64=m
CONFIG_CRYPTO_SHA512_ARM64=m
CONFIG_CRYPTO_SHA512_ARM64_CE=m
CONFIG_CRYPTO_SHA3_ARM64=m
CONFIG_CRYPTO_SM3_ARM64_CE=m
CONFIG_CRYPTO_SM4_ARM64_CE=m
CONFIG_CRYPTO_AES_ARM64=m
CONFIG_CRYPTO_AES_ARM64_NEON_BLK=m
CONFIG_CRYPTO_CHACHA20_NEON=m
CONFIG_CRYPTO_NHPOLY1305_NEON=m
CONFIG_CRYPTO_AES_ARM64_BS=m

and if appropriate

CONFIG_CRYPTO_CRCT10DIF_ARM64_CE=m

(which depends on whether T10DIF support is enabled)

Note that in the case of AES, this is not just a matter of performance - NEON
and bit sliced AES routines implement the AES cipher in a time invariant
matter, and so without them, arm64 CPUs that do not implement the crypto
extensions (such as the Raspberry Pi3) are forced to fall back on the generic,
table based C implementation.
