crypto: skcipher - Make skcipher_walk src.virt.addr const

2025-03-15T08:21:22Z

Mark the src.virt.addr field in struct skcipher_walk as a pointer to const data. This guarantees that the user won't modify the data which should be done through dst.virt.addr to ensure that flushing is done when necessary. Signed-off-by: Herbert Xu

sparc/crc32: expose CRC32 functions through lib

2024-12-02T01:23:01Z

Move the sparc CRC32C assembly code into the lib directory and wire it up to the library interface. This allows it to be used without going through the crypto API. It remains usable via the crypto API too via the shash algorithms that use the library interface. Thus all the arch-specific "shash" code becomes unnecessary and is removed. Note: to see the diff from arch/sparc/crypto/crc32c_glue.c to arch/sparc/lib/crc32_glue.c, view this commit with 'git show -M10'.

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: sparc/crc32c - stop using the shash alignmask

2023-10-27T10:04:24Z

As far as I can tell, "crc32c-sparc64" is the only "shash" algorithm in the kernel that sets a nonzero alignmask and actually relies on it to get the crypto API to align the inputs and outputs. This capability is not really useful, though. To unblock removing the support for alignmask from shash_alg, this patch updates crc32c-sparc64 to no longer use the alignmask. This means doing 8-byte alignment of the data when doing an update, using get_unaligned_le32() when setting a non-default initial CRC, and using put_unaligned_le32() to output the final CRC. Partially tested with: export ARCH=sparc64 CROSS_COMPILE=sparc64-linux-gnu- make sparc64_defconfig echo CONFIG_CRYPTO_CRC32C_SPARC64=y >> .config echo '# CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set' >> .config echo CONFIG_DEBUG_KERNEL=y >> .config echo CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y >> .config make olddefconfig make -j$(getconf _NPROCESSORS_ONLN) qemu-system-sparc64 -kernel arch/sparc/boot/image -nographic However, qemu doesn't actually support the sparc CRC32C instructions, so for the test I temporarily replaced crc32c_sparc64() with __crc32c_le() and made sparc64_has_crc32c_opcode() always return true. So essentially I tested the glue code, not the actual SPARC part which is unchanged. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

sparc: Explicitly include correct DT includes

2023-08-28T18:30:57Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.
