Subject: crypto: ghash-clmulni: specify context size for ghash async algorithm
From: Andrey Ryabinin <[email protected]>
commit 71c6da846be478a61556717ef1ee1cea91f5d6a8 upstream.
Currently context size (cra_ctxsize) doesn't specified for ghash_async_alg. Which means it's zero. Thus crypto_create_tfm() doesn't allocate needed space for ghash_async_ctx, so any read/write to ctx (e.g. in ghash_async_init_tfm()) is not valid.
