Hi, Can someone please explain why are netlink sockets a better communication method between kernel space and userspace ? I know that with IOCTLs we cannot send asynchronous messages to userspace from kernel, and with netlink we can. Are there more things to it? I once heard something about that when passing with IOCTL a pointer from userspace, you can mess it, by advancing it too much for example. But I am not sure. regards, Kevin
