With GSoC approaching, I wrote an article on how to extend Lua with kernel APIs and embed the Lua interpreter into Linux subsystems using Lunatik—an in-kernel Lua runtime that enables dynamic scripting inside the Linux kernel without requir

It has been a while since we have introduced XDPLua, a Lua binding for running scripts inside the XDP (eXpress Data Path) environment using the Lunatik framework. Since then both XDP and Lunatik have evolved quite a bit. Especially, now it

Thanks for sharing this! Is it open source?

Potentially, yes. However, I didn't try it. You could even disable GC completely. Lunatik provides some facilities that could be useful in this scenario as well, such as RCU tables and shared objects. For instance, you could pre-alloca

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 s

Please refer to Section 3 from [1], this was extensively discussed there. [1] https://www.netbsd.org/~lneto/dls14.pdf However, giving you a short answer, we use Lua mainly because it's easy both to extend and to e

One of the main inspirations for Lunatik is the MS Singularity OS [1], which gets rid of kernel/user space division and implements application/process protection by software using programing language resources. The other one is th

Perhaps when we have a fully scriptable operating system, we might call it Lunatix =).

this is because the repository is a Lua fork.. actually, Lunatik started in 2008 [1, 2]. [1] https://sourceforge.net/projects/lunatik/files/ [2] https://www.maxwell.vrac.puc-rio.br/colecao.php

It doesn't use eBPF but we can interoperate.. we have developed XDPLua for this as a GSoC project [1] and then published this work on Netdev 0x14 [2]. [1] https://victornogueirario.github.io/xdplua/ [2] https:&#x
