[PATCH v3 00/12] RISC-V: provide some accelerated cryptography implementations using vector extensions

From: Jerry Shih
Date: Tue Dec 05 2023 - 04:28:16 EST


From: Jerry Shih <bignose1007@xxxxxxxxx>

This series provides cryptographic implementations using the vector crypto
extensions[1] including:
1. AES cipher
2. AES with CBC/CTR/ECB/XTS block modes
3. ChaCha20 stream cipher
4. GHASH for GCM
5. SHA-224/256 and SHA-384/512 hash
6. SM3 hash
7. SM4 cipher

This patch set is based on Heiko Stuebner's work at:

The implementations reuse the perl-asm scripts from OpenSSL[2] with some
changes adapting for the kernel crypto framework.
The perl-asm scripts generate the RISC-V RVV 1.0 instructions and the
opcodes of the vector crypto instructions into `.S` files. We will replace
the vector crypto opcodes with asm mnemonics in the future. It needs lots
of extensions checking for toolchains.

All changes pass the kernel run-time crypto self tests and the extra tests
with vector-crypto-enabled qemu.

This series depend on:
1. kernel 6.6-rc7
Link: https://github.com/torvalds/linux/commit/05d3ef8bba77c1b5f98d941d8b2d4aeab8118ef1
2. support kernel-mode vector

3. vector crypto extensions detection
Link: https://lore.kernel.org/lkml/20231017131456.2053396-1-cleger@xxxxxxxxxxxx/
4. fix the error message:
alg: skcipher: skipping comparison tests for xts-aes-aesni because
xts(ecb(aes-generic)) is unavailable

Updated patches (on current order): 3, 4, 6, 7, 8, 9, 10, 11, 12
New patch: -
Unchanged patch: 1, 2, 5
Deleted patch: 6 in v2

Changelog v3:
- Use asm mnemonics for the instructions in RVV 1.0 extension.
- Use `SYM_TYPED_FUNC_START` for indirect-call asm symbols.
- Update aes xts_crypt() implementation.
- Update crypto function names with the prefix/suffix of `riscv64` or the
specific extensions to avoid the collision with functions in `crypto/`
or `lib/crypto/`.

Changelog v2:
- Do not turn on the RISC-V accelerated crypto kconfig options by
default.
- Assume RISC-V vector extension could support unaligned access in
kernel.
- Turn to use simd skcipher interface for AES-CBC/CTR/ECB/XTS and
Chacha20.
- Rename crypto file and driver names to make the most important
extension at first place.
