Package ebpf is a toolkit for working with eBPF programs. eBPF programs are small snippets of code which are executed directly in a VM in the Linux kernel, which makes them very fast and flexible. Many Linux subsystems now accept eBPF programs. This makes it possible to implement highly application specific logic inside the kernel, without having to modify the actual kernel itself. Since eBPF is a relatively young concept, documentation and user space support is still lacking. Most of the available tools are written in C, and reside in the kernel's source tree. The more mature external projects like libbcc focus on using eBPF for instrumentation and debugging. This leads to certain trade-offs which are not acceptable when writing production services. This package is instead designed for long-running processes which want to use eBPF to implement part of their application logic. It has no run-time dependencies outside of the library and the Linux kernel itself. eBPF code should be compiled ahead of time using clang, and shipped with your application as any other resource. The two main parts are an ELF loader, which reads object files emitted by clang, and facilities to modify and load eBPF programs into the kernel. This package doesn't include code required to attach eBPF to Linux subsystems, since this varies per subsystem. See the examples for possible solutions. ExampleExtractDistance shows how to attach an eBPF socket filter to extract the network distance of an IP host. ExampleSocketELF demonstrates how to load an eBPF program from an ELF, pin it into the filesystem and attach it to a raw socket.
