* payload_main:
* This is the entry point to the payload, it gets branched to form the injected
* shellcode in the JIG response.
* This is the main function of the exploit, its code is position
* indedependent. It copies the actual payload to a safe-from-overwrite memory,
* while it overwrites an existing function from the kernel.
* It will also add necessary syscalls and patch some areas of the kernel before
* returning the control back to it
