    crypto: poly1305 - remove ->setkey() method · b806c0cc
    Eric Biggers authored
    commit a16e772e664b9a261424107784804cffc8894977 upstream.
    
    Since Poly1305 requires a nonce per invocation, the Linux kernel
    implementations of Poly1305 don't use the crypto API's keying mechanism
    and instead expect the key and nonce as the first 32 bytes of the data.
    But ->setkey() is still defined as a stub returning an error code.  This
    prevents Poly1305 from being used through AF_ALG and will also break it
    completely once we start enforcing that all crypto API users (not just
    AF_ALG) call ->setkey() if present.
    
    Fix it by removing crypto_poly1305_setkey(), leaving ->setkey as NULL.
