Canonical title: Fast (Trapless) Kernel Probes Everywhere
Question: Can Linux Kprobes avoid trap overhead without sacrificing broad kernel-code coverage?
Context: Standard Kprobes trap on every hit; optimized probes are faster but cannot instrument much kernel code.
Method: The compiler/linker places strategic NOPs that a transparent Kprobe implementation can patch into trapless probes across nearly all code.
Evaluation: workloads=Linux kernel probe sites; baselines=standard Kprobe; prior optimized Kprobe; metrics=probe cost; kernel-code coverage; results=10x probe performance; 96% coverage vs about 80%
Interpretation: Small compile-time layout support removes a runtime observability tax while preserving compatibility.
Reusable lesson: Reserve cheap patch points during build time for production-safe dynamic instrumentation.
Applicability: Linux tracing, observability, and security instrumentation.
Limits: Needs toolchain/kernel-layout changes; some code and architectures remain unsupported.
