13.2 eBPF Architecture | Syscall Tracing with Extended Berkeley Packet Filters (eBPF)

Explore the internal architecture of extended Berkeley Packet Filter (eBPF) and how it safely runs sandboxed programs directly within the Linux kernel. We break down the roles of the in-kernel verifier, stable tracepoints, and BPF ring buffers designed for high-throughput, zero-copy telemetry. Master how modern kernel instrumentation guarantees system stability while capturing every state change. Key Takeaways & Architecture Concepts: • The eBPF runtime model: JIT compilation, in-kernel verifier guarantees, and bounded loop constraints. • Static Tracepoints vs. Dynamic Kprobes: Stability trade-offs and performance implications under heavy workloads. • BPF Ring Buffer mechanics: Lockless multi-core memory models, zero-copy event delivery, and avoiding perf-buffer event loss. • How kernel verifier safety checks prevent system crashes, null dereferences, and infinite loops.
