crypto: arm/crc32 - add kCFI annotations to asm routines

2024-06-21T12:30:33+00:00

The crc32/crc32c implementations using the scalar CRC32 instructions are
accessed via indirect calls, and so they must be annotated with type ids
in order to execute correctly when kCFI is enabled.

crypto: arm - add missing MODULE_DESCRIPTION() macros

2024-06-21T12:04:18+00:00

With ARCH=arm, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/arm/crypto/aes-arm-bs.o
WARNING: modpost: missing MODULE_DESCRIPTION() in arch/arm/crypto/crc32-arm-ce.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes crct10dif-ce-glue.c and curve25519-glue.c which,
although they did not produce a warning with the arm allmodconfig
configuration, may cause this warning with other configurations.

crypto: arm/sha - fix function cast warnings

2024-02-24T00:41:19+00:00

clang-16 warns about casting between incompatible function types:

arch/arm/crypto/sha256_glue.c:37:5: error: cast from 'void (*)(u32 *, const void *, unsigned int)' (aka 'void (*)(unsigned int *, const void *, unsigned int)') to 'sha256_block_fn *' (aka 'void (*)(struct sha256_state *, const unsigned char *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]
   37 |                                 (sha256_block_fn *)sha256_block_data_order);
      |                                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
arch/arm/crypto/sha512-glue.c:34:3: error: cast from 'void (*)(u64 *, const u8 *, int)' (aka 'void (*)(unsigned long long *, const unsigned char *, int)') to 'sha512_block_fn *' (aka 'void (*)(struct sha512_state *, const unsigned char *, int)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

      |                 ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix the prototypes for the assembler functions to match the typedef.
The code already relies on the digest being the first part of the
state structure, so there is no change in behavior.
