Hi, Got some quick questions, Consider that I am a newbie just studying. 1. How can I subscribe to the list? This link seems to not be valid anymore http://vger.kernel.org/vger-lists.html#bpf 2. What I want to do: My idea is from user space set the pid of a process to the bpf program on the kernel side. On the kernel side I want to have a variable which will have that PID that came from user space. Now,I want to identify writes to memory that process owns. Question: I am not sure if I should be looking to use kernel headers for identifying the memory pages of a process or should I be reading /proc? Can you guys please give me some tips on how to achieve that? Jhonny
