way to replace items, Adapt quickly to meet demand and make business boom. Because Linux is such a large and important project, updates to the kernel can take years to reach end users running stable long-term tracing programs almost anywhere in kernel or user applications. eBPF is a strictly-typed assembly language with a stable instruction set. eBPF programs can be loaded and upgraded in real time without the

confinement mechanism for Linux using eBPF ▶ Users write per-application policy in a simple policy language ▶ Policy is enforced by attaching BPF programs to LSM hooks ▶ Integrates userspace and kernelspace and production-safe ▶ Works out of the box on any vanilla Linux kernel ≥ 5.8 4 / 7 Our Policy Language Rules and Directives Rules specify access to system objects: ▶ fs(file, access) ▶ net(socket to be taken on a block of rules ▶ Add additional context to a block of rules 5 / 7 Our Policy Language Policy at the Function Call Level ▶ #[func " foo" ] → Apply rules only within a call to foo()
