crypto: sha512 - Remove sha512_base.h

2025-06-30T16:26:20Z

sha512_base.h is no longer used, so remove it. Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20250630160320.2888-17-ebiggers@kernel.org Signed-off-by: Eric Biggers

crypto: sha512 - Replace sha512_generic with wrapper around SHA-512 library

2025-06-30T16:26:19Z

Delete crypto/sha512_generic.c, which provided "generic" SHA-384 and SHA-512 crypto_shash algorithms. Replace it with crypto/sha512.c which provides SHA-384, SHA-512, HMAC-SHA384, and HMAC-SHA512 crypto_shash algorithms using the corresponding library functions. This is a prerequisite for migrating all the arch-optimized SHA-512 code (which is almost 3000 lines) to lib/crypto/ rather than duplicating it. Since the replacement crypto_shash algorithms are implemented using the (potentially arch-optimized) library functions, give them cra_driver_names ending with "-lib" rather than "-generic". Update crypto/testmgr.c and one odd driver to take this change in driver name into account. Besides these cases which are accounted for, there are no known cases where the cra_driver_name was being depended on. This change does mean that the abstract partial block handling code in crypto/shash.c, which got added in 6.16, no longer gets used. But that's fine; the library has to implement the partial block handling anyway, and it's better to do it in the library since the block size and other properties of the algorithm are all fixed at compile time there, resulting in more streamlined code.

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: 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
