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/powerpc/crypto/Kconfig

1047e21a - crypto: lib/Kconfig - Fix lib built-in failure when arch is modular

Wed, 12 Feb 2025 04:48:55 +0000

crypto: lib/Kconfig - Fix lib built-in failure when arch is modularThe HAVE_ARCH Kconfig options in lib/crypto try to solve themodular versus built-in problem, but it still fails when thethe LIB option (e.g., CRYPTO_LIB_CURVE25519) is selected externally.Fix this by introducing a level of indirection with ARCH_MAY_HAVEKconfig options, these then go on to select the ARCH_HAVE optionsif the ARCH Kconfig options matches that of the LIB option.Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202501230223.ikroNDr1-lkp@intel.com/Signed-off-by: Herbert Xu List of files: /linux-6.15/arch/powerpc/crypto/Kconfig

7439cfed - powerpc/crc-t10dif: expose CRC-T10DIF function through lib

Mon, 02 Dec 2024 01:20:51 +0000

powerpc/crc-t10dif: expose CRC-T10DIF function through libMove the powerpc CRC-T10DIF assembly code into the lib directory andwire it up to the library interface. This allows it to be used withoutgoing through the crypto API. It remains usable via the crypto API toovia the shash algorithms that use the library interface. Thus all thearch-specific "shash" code becomes unnecessary and is removed.Note: to see the diff from arch/powerpc/crypto/crct10dif-vpmsum_glue.cto arch/powerpc/lib/crc-t10dif-glue.c, view this commit with'git show -M10'.Reviewed-by: Ard Biesheuvel Reviewed-by: Martin K.
