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.
The library is maintained by Cloudflare and Cilium.
See ebpf.io for other projects from the eBPF ecosystem.
Getting Started
A small collection of Go and eBPF programs that serve as examples for building your own tools can be found under examples/.
Contributions are highly encouraged, as they highlight certain use cases of eBPF and the library, and help shape the future of the project.
Getting Help
Please join the #ebpf-go channel on Slack if you have questions regarding the library.
Packages
This library includes the following packages:
- 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 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 allows attaching eBPF to various hooks
- perf allows reading from a
PERF_EVENT_ARRAY - ringbuf allows reading from a
BPF_MAP_TYPE_RINGBUFmap - features implements the equivalent
of
bpftool feature probefor discovering BPF-related kernel features using native Go. - rlimit provides a convenient API to lift
the
RLIMIT_MEMLOCKconstraint on kernels before 5.11.
Requirements
- A version of Go that is supported by upstream
- Linux >= 4.9. CI is run against kernel.org LTS releases. 4.4 should work but is not tested against.
Regenerating Testdata
Run make in the root of this repository to rebuild testdata in all
subpackages. This requires Docker, as it relies on a standardized build
environment to keep the build output stable.
It is possible to regenerate data using Podman by overriding the CONTAINER_*
variables: CONTAINER_ENGINE=podman CONTAINER_RUN_ARGS= make.
The toolchain image build files are kept in testdata/docker/.
