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.</nowiki> | |||
