You might find this interesting: "However, the closest in functionality and intent is Dan Bernstein’s djbdns, which aims to be a minimalist, highly secure DNS server. The latest release of djbdns, including various support tools, is about 10,000 lines of C as measured by sloccount. We expect that it is possible to build a feature-par version with Nail that is an order of magnitude smaller and intend to do so." https://people.csail.mit.edu/nickolai/papers/bangert-nail-langsec.pdf https://people.csail.mit.edu/nickolai/papers/bangert-nail-la... Nail, btw is parser written in the spirit of "language theoretic security", which is a poweful new way of looking at security problems.
