17ec3e71 - crypto: lib/Kconfig - Hide arch options from user

Thu, 27 Feb 2025 07:48:39 +0000

crypto: lib/Kconfig - Hide arch options from userThe ARCH_MAY_HAVE patch missed arm64, mips and s390. But it mayalso lead to arch options being enabled but ineffective becauseof modular/built-in conflicts.As the primary user of all these options wireguard is selectingthe arch options anyway, make the same selections at the lib/cryptooption level and hide the arch options from the user.Instead of selecting them centrally from lib/crypto, simply setthe default of each arch option as suggested by Eric Biggers.Change the Crypto API generic algorithms to select the top-levellib/crypto options instead of the generic one as otherwise thereis no way to enable the arch options (Eric Biggers). Introduce aset of INTERNAL options to work around dependency cycles on theCONFIG_CRYPTO symbol.Fixes: 1047e21aecdf ("crypto: lib/Kconfig - Fix lib built-in failure when arch is modular")Reported-by: kernel test robot Reported-by: Arnd Bergmann Closes: https://lore.kernel.org/oe-kbuild-all/202502232152.JC84YDLp-lkp@intel.com/Signed-off-by: Herbert Xu List of files: /linux-6.15/arch/riscv/crypto/Kconfig

c70dfa4a - crypto: riscv - add vector crypto accelerated AES-CBC-CTS

Tue, 13 Feb 2024 05:54:42 +0000

crypto: riscv - add vector crypto accelerated AES-CBC-CTSAdd an implementation of cts(cbc(aes)) accelerated using the ZvknedRISC-V vector crypto extension. This is mainly useful for fscrypt,where cts(cbc(aes)) is the "default" filenames encryption algorithm. Inthat use case, typically most messages are short and are block-aligned.The CBC-CTS variant implemented is CS3; this is the variant Linux uses.To perform well on short messages, the new implementation processes thefull message in one call to the assembly function if the data iscontiguous. Otherwise it falls back to CBC operations followed by CTSat the end. For decryption, to further improve performance on shortmessages, especially block-aligned messages, the CBC-CTS assemblyfunction parallelizes the AES decryption of all full blocks. Thisimproves on the arm64 implementation of cts(cbc(aes)), which alwayssplits the CBC part(s) from the CTS part, doing the AES decryptions forthe last two blocks serially and usually loading the round keys twice.Tested in QEMU with CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y.Signed-off-by: Eric Biggers Link: https://lore.kernel.org/r/20240213055442.35954-1-ebiggers@kernel.orgSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/crypto/Kconfig

b8d06352 - crypto: riscv - add vector crypto accelerated SM4

Mon, 22 Jan 2024 00:19:21 +0000

crypto: riscv - add vector crypto accelerated SM4Add an implementation of SM4 using the Zvksed extension. The assemblycode is derived from OpenSSL code (openssl/openssl#21923) that wasdual-licensed so that it could be reused in the kernel. Nevertheless,the assembly has been significantly reworked for integration with thekernel, for example by using a regular .S file instead of the so-calledperlasm, using the assembler instead of bare '.inst', and greatlyreducing code duplication.Co-developed-by: Christoph Müllner Signed-off-by: Christoph Müllner Co-developed-by: Heiko Stuebner Signed-off-by: Heiko Stuebner Signed-off-by: Jerry Shih Co-developed-by: Eric Biggers Signed-off-by: Eric Biggers Link: https://lore.kernel.org/r/20240122002024.27477-11-ebiggers@kernel.orgSigned-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/crypto/Kconfig
