Overriding functionality with modules in Linux kernel


c linux module kernel

I realise that the question is three years old, but for the benefit of other people trying to do this sort of thing, the kernel has an interface called kprobes to do just what you needed.

You probably want to hook the system calls (PDF link), which would effectively let you log user-processes calling kernel functions. If you really want to log the kernel use of kernel functions, you want to look into kernel function trace.

I'm not entirely sure I understand what you want to do, but I think that ksplice may be a good solution. It's still under development, so I don't know if it's in any sort of usable condition right now.
