Okay from what the docs say sys_fork take a pt_regs struct. This look right:

struc pt_regs ebx, ecx, edx, esi, edi, ebp, eax, xds, xes, orig_eax, eip, xcs, eflags, esp ,xss
{

.ebx dd ebx
.ecx dd ecx
.edx dd edx
.esi dd esi
.edi dd edik
.ebp dd ebp
.eax dd eax
.xds dd xds
.orig_eax dd orig_eax
.eip dd eip
.xcs dd xcs
.eflags dd eflags
.esp dd esp
.xss dd xss

}

How then does one use the sys_fork function to fork a process?

The correct pt_regs should look like this:

Code:

struc pt_regs
{
  .ebx            dd 0
        .ecx            dd 0
        .edx            dd 0
        .esi            dd 0
        .edi            dd 0
        .ebp            dd 0
        .eax            dd 0
        .xds            dd 0
        .xes            dd 0
        .orig_eax       dd 0
        .eip            dd 0
        .xcs            dd 0
        .eflags         dd 0
        .esp            dd 0
        .xss            dd 0    

}

About the filling the structure... there is not much information about this. I'd say the best you can do is runing a recursive grep for "sys_fork" and/or "pt_regs" on the linux source tree. I bet you find usable info there. Smile
