Playing with ptrace, Part II | Linux Journal
In Part I of this article [LJ, November 2002], we saw how ptrace can be used to trace system calls and change system call arguments. In this article, we investigate advanced techniques like setting breakpoints and injecting code into running programs. Debuggers use these methods to set up breakpoints and execute debugging handlers. As with Part I, all code in this article is i386 architecture-spec

Playing with ptrace, Part I | Linux Journal
Have you ever wondered how system calls can be intercepted? Have you ever tried fooling the kernel by changing system call arguments? Have you ever wondered how debuggers stop a running process and let you take control of the process? If you are thinking of using complex kernel programming to accomplish tasks, think again. Linux provides an elegant mechanism to achieve all of these things: the ptr
