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.

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: sha256 - remove duplicate generic hash init function

2021-12-31T07:10:54Z

crypto_sha256_init() and sha256_base_init() are the same repeated implementations, remove the crypto_sha256_init() in generic implementation, sha224 is the same process. Signed-off-by: Tianjia Zhang 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: lib/sha256 - return void

2020-05-08T05:32:12Z

The SHA-256 / SHA-224 library functions can't fail, so remove the useless return value. Also long as the declarations are being changed anyway, also fix some parameter names in the declarations to match the definitions. Signed-off-by: Eric Biggers Reviewed-by: Jason A.

crypto: sha256 - Merge crypto/sha256.h into crypto/sha.h

2019-09-05T04:54:54Z

The generic sha256 implementation from lib/crypto/sha256.c uses data structs defined in crypto/sha.h, so lets move the function prototypes there too. Signed-off-by: Hans de Goede Signed-off-by: Herbert Xu

crypto: sha256_generic - Switch to the generic lib/crypto/sha256.c lib code

2019-08-22T04:57:35Z

Drop the duplicate generic sha256 (and sha224) implementation from crypto/sha256_generic.c and use the implementation from lib/crypto/sha256.c instead. "diff -u lib/crypto/sha256.c sha256_generic.c" shows that the core sha256_transform function from both implementations is identical and the other code is functionally identical too.

crypto: sha256_generic - Fix some coding style issues

2019-08-22T04:57:35Z

Add a bunch of missing spaces after commas and arround operators. Note the main goal of this is to make sha256_transform and its helpers identical in formatting too the duplcate implementation in lib/sha256.c, so that "diff -u" can be used to compare them to prove that no functional changes are made when further patches in this series consolidate the 2 implementations into 1.
