libbpf src afd8d42b30053be73906631ab652b44560ebc1861056bb2063cd0135183ffcfa Library for working with BPF object files libbpf is a C-based library containing a BPF loader that takes compiled BPF object files and prepares and loads them into the Linux kernel. libbpf takes the heavy lifting of loading, verifying, and attaching BPF programs to various kernel hooks, allowing BPF application developers to focus only on BPF program correctness and performance. The following are the high-level features supported by libbpf: * Provides high-level and low-level APIs for user space programs to interact with BPF programs. The low-level APIs wrap all the bpf system call functionality, which is useful when users need more fine-grained control over the interactions between user space and BPF programs. * Provides overall support for the BPF object skeleton generated by bpftool. The skeleton file simplifies the process for the user space programs to access global variables and work with BPF programs. * Provides BPF-side APIS, including BPF helper definitions, BPF maps support, and tracing helpers, allowing developers to simplify BPF code writing. * Supports BPF CO-RE mechanism, enabling BPF developers to write portable BPF programs that can be compiled once and run across different kernel versions. zeroability <zeroability@fastmail.com> https://github.com/libbpf/libbpf
