Forgive my dumbness, but in: .cra_type = &crypto_aead_type, .cra_u = { .aead = { .setkey = pp_crypto_aead_setkey, .setauthsize = pp_crypto_aead_setauthsize, .decrypt = pp_crypto_aead_dec, .encrypt = pp_crypto_aead_enc, .givencrypt = pp_crypto_aead_genivencrypt, .givdecrypt = pp_crypto_aead_genivdecrypt, .ivsize = AES_BLOCK_SIZE, .maxauthsize = SHA256_DIGEST_SIZE, }, }, Just delete the givencrypt and givdecrypt lines (or set to NULL)?
