# eBPF
|
|
|
|
[](https://pkg.go.dev/github.com/cilium/ebpf)
|
|
|
|
|
|
|
|
ebpf-go 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.
|
|
|
|
See [ebpf.io](https://ebpf.io) for complementary projects from the wider eBPF
|
|
ecosystem.
|
|
|
|
## Getting Started
|
|
|
|
Please take a look at our [Getting Started] guide.
|
|
|
|
[Contributions](https://ebpf-go.dev/contributing) are highly encouraged, as they highlight certain use cases of
|
|
eBPF and the library, and help shape the future of the project.
|
|
|
|
## Getting Help
|
|
|
|
The community actively monitors our [GitHub Discussions](https://github.com/cilium/ebpf/discussions) page.
|
|
Please search for existing threads before starting a new one. Refrain from
|
|
opening issues on the bug tracker if you're just starting out or if you're not
|
|
sure if something is a bug in the library code.
|
|
|
|
Alternatively, [join](https://ebpf.io/slack) the
|
|
[#ebpf-go](https://cilium.slack.com/messages/ebpf-go) channel on Slack if you
|
|
have other questions regarding the project. Note that this channel is ephemeral
|
|
and has its history erased past a certain point, which is less helpful for
|
|
others running into the same problem later.

## Packages
|
|
|
|
This library includes the following packages:
|
|
|
|
* [asm](https://pkg.go.dev/github.com/cilium/ebpf/asm) contains a basic
|
|
assembler, allowing you to write eBPF assembly instructions directly
|
|
within your Go code. (You don't need to use this if you prefer to write your eBPF program in C.)
|
|
* [cmd/bpf2go](https://pkg.go.dev/github.com/cilium/ebpf/cmd/bpf2go) allows
|
|
compiling and embedding eBPF programs written in C within Go code. As well as
|
|
compiling the C code, it auto-generates Go code for loading and manipulating
|
|
the eBPF program and map objects.
|
|
* [link](https://pkg.go.dev/github.com/cilium/ebpf/link) allows attaching eBPF
|
|
to various hooks
|
|
* [perf](https://pkg.go.dev/github.com/cilium/ebpf/perf) allows reading from a
|
|
`PERF_EVENT_ARRAY`
|
|
* [ringbuf](https://pkg.go.dev/github.com/cilium/ebpf/ringbuf) allows reading from a
|
|
`BPF_MAP_TYPE_RINGBUF` map
|
|
* [features](https://pkg.go.dev/github.com/cilium/ebpf/features) implements the equivalent
|
|
of `bpftool feature probe` for discovering BPF-related kernel features using native Go.
|
|
* [rlimit](https://pkg.go.dev/github.com/cilium/ebpf/rlimit) provides a convenient API to lift
|
|
the `RLIMIT_MEMLOCK` constraint on kernels before 5.11.
|
|
* [btf](https://pkg.go.dev/github.com/cilium/ebpf/btf) allows reading the BPF Type Format.
|
|
* [pin](https://pkg.go.dev/github.com/cilium/ebpf/pin) provides APIs for working with pinned objects on bpffs.
|
|
|
|
## Requirements
|
|
|
|
* A version of Go that is [supported by
|
|
upstream](https://golang.org/doc/devel/release.html#policy)
|
|
* CI is run against kernel.org LTS releases. >= 4.4 should work but EOL'ed versions
|
|
are not supported.
