Under linux you can modify the syscall table through a loadable kernel module. This will allow you to modify the behavior of system calls. This may satisfy the restriction that you're not allowed to modify the kernel, since you're doing it dynamically and the underlying code remains the same.

On UNIX Systems, (FreeBSD, Linux, Solaris) is there a way to capture/modify system calls calls from an application with out modifying the kernel (or using kernel modules) - preferably in userspace? The reason I ask is that a group of us are being asked to evaluate a piece of software for my company but they've put some heavy restrictions on how we do it. One of the restriction is that we're not allowed to modify the kernel.
