Get Global Descriptor Table under Linux

Question

i want to know if there is any method to retrieve GDT informations under Linux

Answer 1

You can get/set LDTs using the function modify_ldt (not a real function but a syscall, so you'll have to call it manually).

But for the GDT I don't know. But anyway, AFAIK, the GDT is not changed once the system is booted, so you can read it from the source ;-).
