If you have the Android kernel tree from "git" you can use the "make
menuconfig" command to set the kernel compile-time parameters
(including netfilter and iptables). Android uses a slightly modified
Unix file tree structure where /system is prepended to the standard
Unix tree structure. Most of the userspace C/C++ programs are in /
system/{bin,lib,xbin}. (While there is /system/usr, there is not a
system/usr/{bin,sbin}).
Your userspace executables should be built like the other userspace
executables (they can be dynamically linked against the libraries in
the build tree).
Your executables should probably go in /system/bin, libraries in /
system/lib. These directories are protected from writing by normal
Android applications.
