Merge tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linuxPull crypto library updates from Eric Biggers: "This is the main crypto library pull request for 6.17. The main focus this cycle is on reorganizing the SHA-1 and SHA-2 code, providing high-quality library APIs for SHA-1 and SHA-2 including HMAC support, and establishing conventions for lib/crypto/ going forward: - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares most of the SHA-512 code) into lib/crypto/. This includes both the generic and architecture-optimized code. Greatly simplify how the architecture-optimized code is integrated. Add an easy-to-use library API for each SHA variant, including HMAC support. Finally, reimplement the crypto_shash support on top of the library API. - Apply the same reorganization to the SHA-256 code (and also SHA-224 which shares most of the SHA-256 code). This is a somewhat smaller change, due to my earlier work on SHA-256. But this brings in all the same additional improvements that I made for SHA-1 and SHA-512. There are also some smaller changes: - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For these algorithms it's just a move, not a full reorganization yet. - Fix the MIPS chacha-core.S to build with the clang assembler. - Fix the Poly1305 functions to work in all contexts. - Fix a performance regression in the x86_64 Poly1305 code. - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code. Note that since the new organization of the SHA code is much simpler, the diffstat of this pull request is negative, despite the addition of new fully-documented library APIs for multiple SHA and HMAC-SHA variants. These APIs will allow further simplifications across the kernel as users start using them instead of the old-school crypto API. (I've already written a lot of such conversion patches, removing over 1000 more lines of code. But most of those will target 6.18 or later)"* tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (67 commits) lib/crypto: arm64/sha512-ce: Drop compatibility macros for older binutils lib/crypto: x86/sha1-ni: Convert to use rounds macros lib/crypto: x86/sha1-ni: Minor optimizations and cleanup crypto: sha1 - Remove sha1_base.h lib/crypto: x86/sha1: Migrate optimized code into library lib/crypto: sparc/sha1: Migrate optimized code into library lib/crypto: s390/sha1: Migrate optimized code into library lib/crypto: powerpc/sha1: Migrate optimized code into library lib/crypto: mips/sha1: Migrate optimized code into library lib/crypto: arm64/sha1: Migrate optimized code into library lib/crypto: arm/sha1: Migrate optimized code into library crypto: sha1 - Use same state format as legacy drivers crypto: sha1 - Wrap library and add HMAC support lib/crypto: sha1: Add HMAC support lib/crypto: sha1: Add SHA-1 library functions lib/crypto: sha1: Rename sha1_init() to sha1_init_raw() crypto: x86/sha1 - Rename conflicting symbol lib/crypto: sha2: Add hmac_sha*_init_usingrawkey() lib/crypto: arm/poly1305: Remove unneeded empty weak function lib/crypto: x86/poly1305: Fix performance regression on short messages ...

484c18119f4fbc6bca7c41e64b6fa84133e1057b - lib/crypto: x86/sha512: Migrate optimized SHA-512 code to library

Mon, 30 Jun 2025 18:03:18 +0200

lib/crypto: x86/sha512: Migrate optimized SHA-512 code to libraryInstead of exposing the x86-optimized SHA-512 code via x86-specificcrypto_shash algorithms, instead just implement the sha512_blocks()library function. This is much simpler, it makes the SHA-512 (andSHA-384) library functions be x86-optimized, and it fixes thelongstanding issue where the x86-optimized SHA-512 code was disabled bydefault. SHA-512 still remains available through crypto_shash, butindividual architectures no longer need to handle it.To match sha512_blocks(), change the type of the nblocks parameter ofthe assembly functions from int to size_t. The assembly functionsactually already treated it as size_t.Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20250630160320.2888-15-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/lib/crypto/x86/sha512-avx-asm.S
