Perhaps add a setsockopt > to af_alg_type in order to keep this out of the generic code. What about adding a setauthsize to af_alg_type that is called from the parent setsockopt? I would like to keep all user space interfaces as close together as possible. With a new setsockopt callback, I fear that user space interface handling may be scattered around. Currently I am simply thinking about the following: partent setsockopt: case ALG_SET_AEAD_AUTHSIZE: if (sock->state == SS_CONNECTED) goto unlock; if (!type->setauthsize) goto unlock; err = type->setauthsize(ask->private, optlen); af_alg_type: int (*setauthsize)(void *private, unsigned int authsize); -- Ciao Stephan -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
