(Why is that limitation, btw (see crypto_report > and the use of cru_driver_name?) crypto_report() was intended to provide informations of one implementation of a algorithm, so it was required to specify this algorithm exactly with cru_driver_name. We could extend crypto_report() to provide informations of the algorithm with the highest priority that matches cra_name. Or, we also have crypto_dump_report(). This basically provides informations on all instantiated algorithms, similar to /proc/crypto. We could extend this in a way that you can provide a cra_name. Then it can dump out the informations of all algorithms that match cra_name. -- 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
