I see two potential problems with using Lua bytecode: 1. It's not standartised and it will very likely change in future versions 2. There is no bpf_validate for Lua bytecode. In fact, Lua team abandoned an idea of bytecode validation few years ago. From Lua 5.3 manual: Lua does not check the consistency of binary chunks. Maliciously crafted binary chunks can crash the interpreter. Alex
