What Hacker News says
7 sourcesLunatik v3.6 Released
We are pleased to announce the release of Lunatik v3.6, introducing new features and improvements for in-kernel Lua scripting.
What is Lunatik?
Lunatik is an in-kernel Lua runtime that enables dynamic scripting within the Linux kernel, allowing extensions and modifications without recompilation. It provides a flexible way to develop networking features, security enhancements, and system automation.
What's New in v3.6?
New kernel bindings:
- Netfilter & Xtables – Packet filtering and firewall extensions
- Completion – Efficient synchronization primitives
- FIFO – Kernel-level queue management
Broader Kernel Support – Now compatible with Linux 5.x series
OpenWRT & OpenWiFi support – Expanding Lunatik to embedded and networking environments

I've just glanced at LOAD81 now.. pretty good job! thanks for sharing.. I noted your keyboard event handling (using SDL).. we have something very related to this in Lunatik (at the kernel level, of course) [1]. We've a kinda fun script that uses keyboard event handling to implement a "key locker" using Konami code [2].

However, it was conceived for extensibility and flexibility in general, in the spirit of [6]. It has been used also for scripting CPU frequency scaling, debugging, application sandboxing among others [7,8].
