crypto: rmd160 - fix Kconfig "its" grammar

crypto: lib - make the sha1 library optional

2022-07-15T08:43:59+00:00

Since the Linux RNG no longer uses sha1_transform(), the SHA-1 library is no longer needed unconditionally. Make it possible to build the Linux kernel without the SHA-1 library by putting it behind a kconfig option, and selecting this new option from the kconfig options that gate the remaining users: CRYPTO_SHA1 for crypto/sha1_generic.c, BPF for kernel/bpf/core.c, and IPV6 for net/ipv6/addrconf.c. Unfortunately, since BPF is selected by NET, for now this can only make a difference for kernels built without networking support. Signed-off-by: Eric Biggers Reviewed-by: Jason A.

crypto: fips - make proc files report fips module name and version

2022-07-15T08:43:22+00:00

FIPS 140-3 introduced a requirement for the FIPS module to return information about itself, specifically a name and a version. These values must match the values reported on FIPS certificates. This patch adds two files to read a name and a version from: /proc/sys/crypto/fips_name /proc/sys/crypto/fips_version v2: removed redundant parentheses in config entries. v3: move FIPS_MODULE_* defines to fips.c where they are used. v4: return utsrelease.h inclusion Signed-off-by: Simo Sorce Signed-off-by: Vladis Dronov Signed-off-by: Herbert Xu

crypto: aria - Implement ARIA symmetric cipher algorithm

2022-07-15T08:38:19+00:00

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: s390 - do not depend on CRYPTO_HW for SIMD implementations

2022-07-07T03:04:06+00:00

Various accelerated software implementation Kconfig values for S390 were mistakenly placed into drivers/crypto/Kconfig, even though they're mainly just SIMD code and live in arch/s390/crypto/ like usual. This gives them the very unusual dependency on CRYPTO_HW, which leads to problems elsewhere. This patch fixes the issue by moving the Kconfig values for non-hardware drivers into the usual place in crypto/Kconfig. Acked-by: Herbert Xu Signed-off-by: Jason A.

crypto: memneq - move into lib/

2022-06-12T06:51:51+00:00

This is used by code that doesn't need CONFIG_CRYPTO, so move this into lib/ with a Kconfig option so that it can be selected by whatever needs it. This fixes a linker error Zheng pointed out when CRYPTO_MANAGER_DISABLE_TESTS!=y and CRYPTO=m: lib/crypto/curve25519-selftest.o: In function `curve25519_selftest': curve25519-selftest.c:(.init.text+0x60): undefined reference to `__crypto_memneq' curve25519-selftest.c:(.init.text+0xec): undefined reference to `__crypto_memneq' curve25519-selftest.c:(.init.text+0x114): undefined reference to `__crypto_memneq' curve25519-selftest.c:(.init.text+0x154): undefined reference to `__crypto_memneq' Reported-by: Zheng Bin Cc: Eric Biggers Cc: stable@vger.kernel.org Fixes: aa127963f1ca ("crypto: lib/curve25519 - re-add selftests") Signed-off-by: Jason A.

crypto: blake2s - remove shash module

2022-06-10T08:43:49+00:00

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

2022-06-10T08:40:17+00:00

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
