As a hint, look at the prototype of sys_execve : asmlinkage int sys_execve(struct pt_regs regs) NOT asmlinkage int sys_execve(struct pt_regs * regs) and think about how the system call might need to change a process's saved registers to ensure when it returns to user space, it executes the startup code for the execve()d image. We get quite a few people asking about sys call overloading - my suggestion is to check on kernelnewbies.org/patches/ for existing things that do this like overloader or syscalltracker (note: I haven't actually looked at these sources, they may be wrong). regards john -- "Beware of bugs in the above code; I have only proved it correct, not tried it." - Donald Knuth - Kernelnewbies: Help each other learn about the Linux kernel.
