As I mentioned to Richard Jonson, it can be considered as ioctl. ioctl-ng! Unified interface (as ioctl) can be used for any type of modules. It is just a bit extended ioctl :) And _yes_, it can be used to turn on/off binary-only callbacks. Remember pwc - closed part can register callback and open part can send message, or even closed part can register notification when open part registers itself and begin to "trash the kernel". I understand that it is not right way to include it is into the kernel, but I personally do not understand how it is different=20 from just extended ioctl. It was designed to be usefull and convenient, and it is. BTW, any binary-only module can _itself_ create netlink socket with input callback. And that is all - it will be absolutely the same as above. One may consider connector as yet-another-netlink-helper. --=20 Evgeniy Polyakov Crash is better than data corruption. -- Art Grabowski --=-8fpkCBNjFfMFdPaA8Oer Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) iD8DBQBBU5cwIKTPhE+8wY0RArB9AJ9BVtouc/+Y4NtRR36frbG5W/k/gACeKd9o Va1gj+T3Fd5AXJOAOMWsLpU= =mKmD -----END PGP SIGNATURE----- --=-8fpkCBNjFfMFdPaA8Oer--
