crypto: sha256 - support arch-optimized lib and expose through shash

2025-05-05T05:38:12Z

As has been done for various other algorithms, rework the design of the SHA-256 library to support arch-optimized implementations, and make crypto/sha256.c expose both generic and arch-optimized shash algorithms that wrap the library functions. This allows users of the SHA-256 library functions to take advantage of the arch-optimized code, and this makes it much simpler to integrate SHA-256 for each architecture. Note that sha256_base.h is not used in the new design. It will be removed once all the architecture-specific code has been updated. Move the generic block function into its own module to avoid a circular dependency from libsha256.ko => sha256-$ARCH.ko => libsha256.ko. Signed-off-by: Eric Biggers Add export and import functions to maintain existing export format. Signed-off-by: Herbert Xu

crypto: lib/sha256 - Move partial block handling out

2025-05-05T05:32:01Z

Extract the common partial block handling into a helper macro that can be reused by other library code. Also delete the unused sha256_base_do_finalize function. Signed-off-by: Herbert Xu

crypto: sha256_base - Remove partial block helpers

2025-04-23T07:52:46Z

Now that all sha256_base users have been converted to use the API partial block handling, remove the partial block helpers. Signed-off-by: Herbert Xu

crypto: riscv/sha256 - Use API partial block handling

2025-04-23T07:52:45Z

Use the Crypto API partial block handling. Signed-off-by: Herbert Xu

crypto: x86/sha256 - Use API partial block handling

2025-04-23T07:52:36Z

Use the Crypto API partial block handling. Also remove the unnecessary SIMD fallback path. Signed-off-by: Herbert Xu

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

crypto: lib/sha256 - Use generic code from sha256_base

2023-05-19T08:45:43Z

Instead of duplicating the sha256 block processing code, reuse the common code from crypto/sha256_base.h. Signed-off-by: Herbert Xu

crypto: sha - split sha.h into sha1.h and sha2.h

2020-11-20T03:45:33Z

Currently contains declarations for both SHA-1 and SHA-2, and contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split into two headers and , and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

crypto: hash - Use memzero_explicit() for clearing state

2020-10-30T06:35:03Z

Without the barrier_data() inside memzero_explicit(), the compiler may optimize away the state-clearing if it can tell that the state is not used afterwards. Signed-off-by: Arvind Sankar Acked-by: Ard Biesheuvel Signed-off-by: Herbert Xu
