crypto: api - Add scaffolding to change completion function signature

2023-05-17T09:53:40Z

[ Upstream commit c35e03eaece71101ff6cbf776b86403860ac8cc3 ] The crypto completion function currently takes a pointer to a struct crypto_async_request object. However, in reality the API does not allow the use of any part of the object apart from the data field. For example, ahash/shash will create a fake object on the stack to pass along a different data field. This leads to potential bugs where the user may try to dereference or otherwise use the crypto_async_request object. This patch adds some temporary scaffolding so that the completion function can take a void * instead. Once affected users have been converted this can be removed. The helper crypto_request_complete will remain even after the conversion is complete. It should be used instead of calling the completion function directly.

crypto: aria - Implement ARIA symmetric cipher algorithm

2022-07-15T08:38:19Z

ARIA(RFC 5794) is a symmetric block cipher algorithm. This algorithm is being used widely in South Korea as a standard cipher algorithm. This code is written based on the ARIA implementation of OpenSSL. The OpenSSL code is based on the distributed source code[1] by KISA. ARIA has three key sizes and corresponding rounds. ARIA128: 12 rounds. ARIA192: 14 rounds. ARIA245: 16 rounds. [1] https://seed.kisa.or.kr/kisa/Board/19/detailView.do (Korean) Signed-off-by: Taehee Yoo Signed-off-by: Herbert Xu

crypto: blake2s - remove shash module

2022-06-10T08:43:49Z

BLAKE2s has no currently known use as an shash. Just remove all of this unnecessary plumbing. Removing this shash was something we talked about back when we were making BLAKE2s a built-in, but I simply never got around to doing it. So this completes that project. Importantly, this fixs a bug in which the lib code depends on crypto_simd_disabled_for_test, causing linker errors. Also add more alignment tests to the selftests and compare SIMD and non-SIMD compression functions, to make up for what we lose from testmgr.c.

crypto: x86/polyval - Add PCLMULQDQ accelerated implementation of POLYVAL

2022-06-10T08:40:17Z

Add hardware accelerated version of POLYVAL for x86-64 CPUs with PCLMULQDQ support. This implementation is accelerated using PCLMULQDQ instructions to perform the finite field computations. For added efficiency, 8 blocks of the message are processed simultaneously by precomputing the first 8 powers of the key. Schoolbook multiplication is used instead of Karatsuba multiplication because it was found to be slightly faster on x86-64 machines. Montgomery reduction must be used instead of Barrett reduction due to the difference in modulus between POLYVAL's field and other finite fields. More information on POLYVAL can be found in the HCTR2 paper: "Length-preserving encryption with HCTR2": https://eprint.iacr.org/2021/1441.pdf Signed-off-by: Nathan Huckleberry Reviewed-by: Ard Biesheuvel Reviewed-by: Eric Biggers Signed-off-by: Herbert Xu
