TripleCross VS honey-potion

This is a good write-up and I like the diagrams. What appears to still be missing in an "off switch". AFAIK there are still no kernel boot time commands to disable eBPF entirely. I have to recompile the kernel to disable it.

eBPF has the potential for file-less malware to run hidden from detection and I foresee the ability to tickle ring -3 (and -4?) CPU within CPU functions while bypassing local firewalls.

Here is some example code of what people already know how to do today and this list will grow as people discover more capabilities. [1][2][3][4][5] These do require some privileges to insert but will remain running and hidden until reboot.

Hi all! We are working on an eBPF backend for Elixir. It's called Honey Potion. The project is under development, but it is possible to write some useful programs at this point. For instance, in this video, one of the guys involved explains how to write a program to count system calls.

We have been working on an eBPF backend for the Elixir programming language. The current implementation is on this branch. EBPF is a bit like a virtual machine that runs on the Linux kernel. EBPF programs are typically used to implement network applications. The most interesting aspect of the backend is that Linux uses a verifier to ensure that eBPF programs always terminate and only access memory within allocated bounds.

Hi! We have been translating Elixir to C (which we translate to eBPF) in HoneyPotion. We used mostly Chapter 15 of Appel's Modern Compiler Implementation in Java to implement the code generator (that's "15. Functional Programming Languages"). I think the choice of C has been good thus far. The implementation of Elixir's pattern matching took much work, but if we had chosen a higher level target, we would still have to translate that to eBPF. Here's the entry point for the translator.

We have been working on a tool that translates Elixir to eBPF. We actually translate eBPF to C. Now that we have more stuff working, I really wonder if generating C was a good choice.

That's exactly what Honey Potion does, when we translate Elixir into Linux' eBPF!
