crypto: sparc/crc32c - stop using the shash alignmask

2023-10-27T10:04:24+00:00

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.

sparc: Explicitly include correct DT includes

2023-08-28T18:30:57+00:00

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.

crypto: Kconfig - simplify cipher entries

2022-08-26T10:50:43+00:00

Shorten menu titles and make them consistent:
- acronym
- name
- architecture features in parenthesis
- no suffixes like " algorithm", "support", or
  "hardware acceleration", or "optimized"

Simplify help text descriptions, update references, and ensure that
https references are still valid.

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

2020-11-20T03:45:33+00:00

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: sparc - rename sha256 to sha256_alg

2020-07-16T11:49:04+00:00

To avoid a naming collision when we add a sha256() library function,
rename the "sha256" static variable in sha256_glue.c to "sha256_alg".
For consistency, also rename "sha224" to "sha224_alg".
