System call tracking method of kernel source code level
TLDR
In this paper, a system call tracking method of a kernel source code level is described, in which a file containing a call number capture function is added under a same level directory of an assembly file called by a Linux Kernel source code implement system.Abstract:
The invention discloses a system call tracking method of a kernel source code level The method comprises the steps that (1) a file containing a system call number capture function is added under a same level directory of an assembly file called by a Linux kernel source code implement system; (2) an assembly instruction is used to call the system call number capture function to acquire a system call number; (3) the acquired system call number is stored for recording and frequency statistics to realize system call tracking According to the system call tracking method of the kernel source codelevel, by modifying a Linux kernel source code, a system call detection module is added in an appropriate position of the kernel source code, and all system call behaviors in a Linux are captured andrecorded in real timeread more

Method for analyzing dynamic execution of Linux kernel
TL;DR: In this paper, a method for tracking and analyzing functions and statements involved in the dynamic executing process of a kernel of an operating system is presented, which comprises the following steps of: expanding open source programs strace, KFT, tags and gcov, so that these programs are enabled to track each executable file on the original basis; meanwhile, filtering system call information and other information of a corresponding tracked executable file in the executing process; storing these information into a new established database; and finally displaying relevant information on a webpage and then linking and displaying a call tree, wherein
