It is theoretically possible to interact with a network interface using a single character device, but because it would be exceptionally difficult, the kernel uses other I/O interfaces 注意 并非所有设备都有设备文件,因为块设备和字符设备的I/O接口并不适用于所有情况。例如,网络接口没有设备文件。理论...
Linux 存在众多 tracing tools,比如 ftrace、perf,他们可用于内核的调试、提高内核的可观测性。众多的工具也意味着繁杂的概念,诸如tracepoint、trace events、kprobe、eBPF 等,甚至让人搞不清楚他们到底是干什么的。本文尝试理清这些概念。 注入Probe 的机制Probe Handler ...
