Linux核心模式下的用户进程研究

Research of Executing User Programs in Linux Kernel Mode

文章通过剖析Linux核心系统调用的基本原理,提出了一种在Linux核心模式下执行用户进程的解决方案,该方案不必修改Linux核心源码,并能方便地实现用户进程在核心模式和用户模式之间的自由切换。文章详细论述了方案的具体实现及其某些相关问题,对其主要应用也做了一定程度的介绍。

After investigating the basic principle of system calls in Linux,the paper provides a method to execute user programs in kernel mode without modifying Linux kernel sources.The method is also easy for user programs to switch between kernel mode and user mode freely.We have described in detail how to implement this method and analyzed some relevant problems.The main applications of it are also introduced.
