libbpfgo is a Go library for working with Linux's eBPF. It was created for Tracee, our open source Runtime Security and eBPF tracing tools written in Go. If you are interested in eBPF and it's applications, check out Tracee on Github:

libbpfgo is built around libbpf - the standard library for interacting with eBPF from userspace, which is a C library maintained in Linux upstream. We have created libbpfgo as a thin Go wrapper around libbpf.


libbpfgo is using CGO to interop with libbpf and will expect to be linked with libbpf at run or link time. Simply importing libbpfgo is not enough to get started, and you will need to fulfill the required dependency in one of the following ways:

  1. Install the libbpf as a shared object in the system. Libbpf may already be packaged for you distribution, if not, you can build and install from source. More info here.
  2. Embed libbpf into your Go project as a vendored dependency. This means that the libbpf code is statically linked into the resulting binary, and there are no runtime dependencies. Tracee takes this approach and you can take example from it's Makefile.


libbpfgo tries to make it natural for Go developers to use, by abstracting away C technicalities. For example, it will translate low level return codes into Go error, it will organize functionality around Go struct, and it will use channel as to let you consume events.

In a high level, this is a typical workflow for working with the library:

  1. Compile your bpf program into an object file.
  2. Initialize a Module struct - that is a unit of BPF functionality around your compiled object file.
  3. Load bpf programs from the object file using the BPFProg struct.
  4. Attach BPFProg to system facilities, for example to "raw tracepoints" or "kprobes" using the BPFProg's associated functions.
  5. Instantiate and manipulate BPF Maps via the BPFMap struct and it's associated methods.
  6. Instantiate and manipulate Perf Buffer for communicating events from your BPF program to the driving userspace program, using the RingBuffer struct and it's associated objects.


// initializing
import bpf ""
bpfModule := bpf.NewModuleFromFile(bpfObjectPath)

// maps
mymap, _ := bpfModule.GetMap("mymap")
mymap.Update(key, value)

// ring buffer
rb, _ := bpfModule.InitRingBuffer("events", eventsChannel, buffSize)
e := <-eventsChannel

Please check our github milestones for an idea of the project roadmap. The general goal is to fully implement/expose libbpf's API in Go as seamlessly as possible.
