Hi.
I don't know Linux kernel well, but I need to find a way to send data from a kernel module to a user application. I read about the netlink sockets, they could solve my problem, but I can't find a good tutorial related to the last kernel versions, and I can't find working examples. Do you know if there are good tutorials about them?

I accept any suggestions, even if they are about other ways to send data from a kernel module to a user application (not only about netlink sockets).
Thanks!
