Re: Netlink event listener in kernel

Thanks for your reply. I think I will go with the notification chains, 

but I'll definitely  have a look at your solution. For sure I'll learn 

many things about netlink.

    Hello,

    I'm new to this list and also to kernel development.

    I'd like to get notified when some specific event happen in the
    kernel, like for example when a network interface goes up, or when a
    new wireless Access Point has been discovered. In fact, all the
    events I'd like to catch are broadcasted over netlink.

    I found a lot of documentation about the communication between
    kernel and userland using netlink, but could hardly find
    documentation about kernel to kernel netlink usage.

    What's the appropriate mechanism to catch the events I'm interested
    in? And provided opening a netlink socket in the kernel is the way
    to go, could you point me to relevant documentation or code example?

    Regards,
    Martin
