The cipher_null crypto_alg cipher is never used in a meaningful way, given that it is always wrapped in ecb(), which has its own dedicated implementation. IOW, the cipher_null crypto_alg should never be used to implement the ecb(cipher_null) skcipher, and using it for other things is bogus. However, it is accessible from user space, and due to the nature of the AF_ALG interface, it may be wrapped in arbitrary ways, exposing issues in template code that wasn't written with block ciphers with a block size of '1' in mind. So drop this code. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Eric Biggers <ebiggers@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
