cgroup2: port over eBPF device controller from crun The implementation is based on https://github.com/containers/crun/blob/0.10.2/src/libcrun/ebpf.c Although ebpf.c is originally licensed under LGPL-3.0-or-later, the author Giuseppe Scrivano agreed to relicense the file in Apache License 2.0: https://github.com/opencontainers/runc/issues/2144#issuecomment-543116397 See libcontainer/cgroups/ebpf/devicefilter/devicefilter_test.go for tested configurations.

eBPF
-------
[![](https://godoc.org/github.com/cilium/ebpf?status.svg)](https://godoc.org/github.com/cilium/ebpf)
eBPF is a pure Go library that provides utilities for loading, compiling, and debugging eBPF programs. It has minimal external dependencies and is intended to be used in long running processes.
[ebpf/asm](https://godoc.org/github.com/cilium/ebpf/asm) contains a basic assembler.
The library is maintained by [Cloudflare](https://www.cloudflare.com) and [Cilium](https://www.cilium.io). Feel free to [join](https://cilium.herokuapp.com/) the [libbpf-go](https://cilium.slack.com/messages/libbpf-go) channel on Slack.
## Current status
The package is production ready, but **the API is explicitly unstable
right now**. Expect to update your code if you want to follow along.
