Abstract

Software developers use #ifdef statements to support code configurability, allowing software product diversification. But because functions can be in many executions paths that depend on complex combinations of configuration options, the introduction of an #ifdef for a given purpose (such as adding a new feature to a program) can enable unintended function calls, which can be a source of vulnerabilities. Part of the difficulty lies in maintaining mental models of all dependencies. We propose analytic visualizations of the variational callgraph to capture dependencies across configurations and create visualizations to demonstrate how it would help developers visually reason through the implications of diversification, for example through visually doing change impact analysis.
可视化Linux内核的变写法:一种推断依赖关系的方法[海报]
软件开发人员使用#ifdef语句来支持代码可配置性,从而允许软件产品多样化。但是,由于函数可能处于依赖于配置选项的复杂组合的许多执行路径中,因此为给定目的(例如向程序添加新特性)引入#ifdef可能会启用意外的函数调用,这可能是漏洞的来源。部分困难在于维护所有依赖关系的心智模型。我们建议对变分曲线图进行分析可视化,以捕获跨配置的依赖关系,并创建可视化,以演示它将如何帮助开发人员可视化地推断多样化的含义,例如通过可视化地进行变更影响分析。
