Ehm, then maybe it's not supposed to be in the form of module? maybe
it's better made as additional function patched into the kernel? This
way you have advantages:
Well, actually I tried first that approach, but inexplicably to me, the
kernel crashes instantaneously when the function to export data is
called. So I put the function in a module, cut and paste, and it worked
fine. If it helps I'll send the culprit function.
1. no overhead of symbol resolve and function indirect call
2. you can detect the hypercall event the kernel in the stage where
it's not ready to accept modules (well, AFAIK, hypercalls might do
something like preparing initial guess IDT/GDT, right?)
Yes, you're right about IDT/GDT, in fact I'm already detecting hcalls
like those, and the next step is to export them to do a deeper analysis.
