crypto: scatterwalk - Remove obsolete PageSlab check

2021-06-28T03:28:08Z

As it is now legal to call flush_dcache_page on slab pages we no longer need to do the check in the Crypto API. Reported-by: Ira Weiny Signed-off-by: Herbert Xu

crypto: api - Move crypto attr definitions out of crypto.h

2021-06-24T06:51:35Z

The definitions for crypto_attr-related types and enums are not needed by most Crypto API users. This patch moves them out of crypto.h and into algapi.h/internal.h depending on the extent of their use. Signed-off-by: Herbert Xu

crypto: api - remove CRYPTOA_U32 and related functions

2021-06-17T07:07:31Z

According to the advice of Eric and Herbert, type CRYPTOA_U32 has been unused for over a decade, so remove the code related to CRYPTOA_U32. After removing CRYPTOA_U32, the type of the variable attrs can be changed from union to struct. Signed-off-by: Liu Shixin Reviewed-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: shash - avoid comparing pointers to exported functions under CFI

2021-06-17T07:07:31Z

crypto_shash_alg_has_setkey() is implemented by testing whether the .setkey() member of a struct shash_alg points to the default version, called shash_no_setkey(). As crypto_shash_alg_has_setkey() is a static inline, this requires shash_no_setkey() to be exported to modules. Unfortunately, when building with CFI, function pointers are routed via CFI stubs which are private to each module (or to the kernel proper) and so this function pointer comparison may fail spuriously. Let's fix this by turning crypto_shash_alg_has_setkey() into an out of line function.

crypto: poly1305 - fix poly1305_core_setkey() declaration

2021-04-02T07:28:12Z

gcc-11 points out a mismatch between the declaration and the definition of poly1305_core_setkey(): lib/crypto/poly1305-donna32.c:13:67: error: argument 2 of type ‘const u8[16]’ {aka ‘const unsigned char[16]’} with mismatched bound [-Werror=array-parameter=] 13 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 raw_key[16]) | ~~~~~~~~~^~~~~~~~~~~ In file included from lib/crypto/poly1305-donna32.c:11: include/crypto/internal/poly1305.h:21:68: note: previously declared as ‘const u8 *’ {aka ‘const unsigned char *’} 21 | void poly1305_core_setkey(struct poly1305_core_key *key, const u8 *raw_key); This is harmless in principle, as the calling conventions are the same, but the more specific prototype allows better type checking in the caller. Change the declaration to match the actual function definition. The poly1305_simd_init() is a bit suspicious here, as it previously had a 32-byte argument type, but looks like it needs to take the 16-byte POLY1305_BLOCK_SIZE array instead.

random: initialize ChaCha20 constants with correct endianness

2021-04-02T07:28:12Z

On big endian CPUs, the ChaCha20-based CRNG is using the wrong endianness for the ChaCha20 constants. This doesn't matter cryptographically, but technically it means it's not ChaCha20 anymore. Fix it to always use the standard constants.
