For more info see [What is eBPF](https://ebpf.io/what-is-ebpf). Aya is an eBPF library built with a focus on operability and developer experience. It does not rely on [libbpf] nor [bcc] - it's built from the ground up purely in Rust, using only the [libc] crate to execute syscalls. With BTF support and when linked with musl, it offers a true [compile once, run everywhere solution][co-re], where a single self-contained binary can be deployed on many linux distributions and kernel versions. Some of the major features provided include: * Support for the **BPF Type Format** (BTF), which is transparently enabled when supported by the target kernel. This allows eBPF programs compiled against one kernel version to run on different kernel versions without the need to recompile. * Support for function call relocation and global data maps, which allows eBPF programs to make **function calls** and use **global variables and initializers**. * **Async support** with both [tokio] and [async-std]. * Easy to deploy and fast to build: aya doesn't require a kernel build or compiled headers, and not even a C toolchain; a release build completes in a matter of seconds.

The following example shows how to use a `BPF_PROG_TYPE_CGROUP_SKB` program with aya: ```rust use std::fs::File; use aya::Ebpf; use aya::programs::{CgroupSkb, CgroupSkbAttachType}; // load the BPF code let mut ebpf = Ebpf::load_file("ebpf.o")?; // get the `ingress_filter` program compiled into `ebpf.o`. let ingress: &mut CgroupSkb = ebpf.program_mut("ingress_filter")?.try_into()?; // load the program into the kernel ingress.load()?; // attach the program to the root cgroup. `ingress_filter` will be called for all // incoming packets. let cgroup = File::open("/sys/fs/cgroup/unified")?; ingress.attach(cgroup, CgroupSkbAttachType::Ingress)?; ``` ## Contributing Please see the [contributing guide](https://github.com/aya-rs/aya/blob/main/CONTRIBUTING.md). ## License Aya is distributed under the terms of either the [MIT license] or the [Apache License] (version 2.0), at your option.
