But you gave me a good start, I will have to check some of the root kits in order to see how things happen there. Actually, I want to see similarities between user space way of linking/loading compared to kernel space. Have not been able to figure out completely yet at conceptual level. I have gone through module.c file and insmod utility. Any pointers to earlier such attempts would be helpful. -Leo.
