Hey,
I am one of the developers of the Commotion project. OpenWRT can be a confusing system. Let me help you find what you are looking for. The Commotion-router repo above is contains our setup scripts that make it easier for new users like you to build our software from source. If you look at the feeds.conf file you will find the exact sources we are pulling in to the openWRT build system for compilation. The most important line, for your concerns about backdoors would be the third line of that file. That line pulls in the master branch of the repo commotion-feed. This repository is full of makefiles. These makefiles specify how to build the source code into the compiled binary your pointed to before. If you follow the follow the install instructions that were poster earlier and then explore the curses (command line GUI) menu for make menuconfig you can explore the exactly what packages are going to be built for the specific architecture. (If you are curious about tampering we sadly have not had the time or funding to do deterministic builds, so I suggest you build it from source yourself so that you can examine the code.) Now, each item in the menuconfig references a "feed." You can look at the feeds.conf file in the current directory, and the various makefiles in the feeds folder to explore where exactly things are being pulled from. Our source code will use the git repo's specified in the makefiles in commotion-feed on the master branch. You can find all of those in our github, because we are an open-source project. If you have any concerns about specific lines of code that have been implemented I beg of you to submit a bug to the repo you find a problem with. We want every possible opportunity better our code. While we have done internal testing, I hope that with eyes like yours looking over the code we will find more bugs that we can address in the future. If you have any questions I will try to follow this thread the best I can, and am elationfoundation on github. You can also find most of the developers and our field experts on freenode at #commotion. I have built, and debugged, far too many openWRT images. So, If you do need assistance jump on #commotion during Americas East Coast working hours and I will be glad to help you.
I hope this helped. OpenWRT's build system is a beautiful, but complex being.
