Description

Implement https://redmine.openinfosecfoundation.org/issues/3307#note-12:

  • vendor a specific version in
  • disallow modules by default (or at all)
  • do proper sandboxing, both for security and performance
  • enable it by default so rule vendors can rely on it to be there

Neovim has some discussion on why they use Lua 5.1 vs other versions:

https://github.com/neovim/neovim/wiki/FAQ#why-lua-51-instead-of-lua-53

Also, rlua, the previously most popular Lua bindings for Rust started with Lua 5.3 I think. 5.1 came after due to popular demand. mlua, a fork of rlua that seems to be more popular now, and also supports luajit 5.1.

By using one of these crates we can get Lua vendored for free.
