hi, sorry but here (GMT+2), it is just the morning. Soo I have put three versions of my code: unicast_wait.tgz => is a basic code taken from the website www.linuxjournal.com/article/7356, it works but it is only for understanding netlink socks. threads.tgz => similar implementation but with a thread and a while(1) => just to see how threads works. unicast_current.tgz => my current program As you will see, my code is not very good, it is my first time in the kernel, so I am trying many things but without thinking about mutex, concurency etc... Some information about my work: I would like to capture trafic on infiniband devices using traps in kernel. I have to dump information from specific module and forward this to a userspace process. that's why I was thinking about netlink socket. For my current program, I will make a trap on Infiniband module to my module in order to send informations on netlink socket. I just have to know the pid of my userspace process: I will send the pid using the callback function of netlink_kernel_create. In order to learn how to program in kernel, i use: Linux_device_drivers_3rd_edition OReilly-Understanding_The_Linux.Kernel_3rd If you can suggest me other references.
