Userland -> Kernel communication

Userland -> Kernel communication

[Catalin BOIE]

Hello!

I wish to give me some pointers to how to communicate with a kernel module
from userland.
May I use sockets?

Thanks in advance!

You can use the /proc interface or a device file
(in /dev) depending on what type of comunication you need. 
These are the most common ways, not sure if there are more.

I don't think so.

You can use copy_to/from_user functions present in kernel space, provided
you have valid userland pointers
also put_user/get_user for single datum transfer.
