Add a macro which replaces the use of a Variable Length Array In Struct (VLAIS) with a C99 compliant equivalent. This macro instead allocates the appropriate amount of memory using an char array. The new code can be compiled with both gcc and clang. struct shash_desc contains a flexible array member member ctx declared with CRYPTO_MINALIGN_ATTR, so sizeof(struct shash_desc) aligns the beginning of the array declared after struct shash_desc with long long. No trailing padding is required because it is not a struct type that can be used in an array. The CRYPTO_MINALIGN_ATTR is required so that desc is aligned with long long as would be the case for a struct containing a member with CRYPTO_MINALIGN_ATTR. If you want to get to the ctx at the end of the shash_desc as before you can do so using shash_desc_ctx(shash) Signed-off-by: Behan Webster <behanw@converseincode.com> Reviewed-by: Mark Charlebois <charlebm@gmail.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Cc: Michał Mirosław <mirqus@gmail.com> |
