[line-devel] int 80 and line operation

[Michael S. <ms...@ac...>]

I've been able to hook int 80 in a kernel mode device driver and send the
eax register and the process ID via a local procedure call to a user mode
application. which can be debugged using vc++. sending the other registers
shouldnt be a problem.

Theres also some code that creates a process and emptys it out so that It is
free to have raw linux executables mapped into it.

this is developed with vc++ and the NT ddk. It runs under 4.0 and 2000
 I really dont have much time to mess around with this anymore and
would be happy have help with it.

My thoughts on how to advance the project
1) Modify the kernel level driver to pass all the registers to the port
	a) the ring0 prolog for the interrupt handler trashes a register.
	b) slight modifications to passing the data through the port.
2) figure out why the kernel mode driver fails to initialize the first time
it is loaded.
3) Merge the port server with the user-mode application that calls the
kernel mode driver to set up the interrupt handler
4) Merge the code to create an empty process into the user-mode application
5) poke into that process an int 80 that calls execve
6) go nuts implementing apis in the user mode code.
7) move code into the kernel mode device driver so system calls dont have to
jump into and out of kernel mode all the time.
