Embodiment Construction

[0025] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0026] attached figure 1 It is a schematic diagram of the structure of the Linux operating system. The Linux application (software) in the figure runs on the Linux kernel. Whenever a Linux system call needs to be called, it enters the kernel through the "int 0x80" instruction, and the specific system call number and parameters are passed through the stack. There is a system call mechanism in the kernel, which handles some operations and activities that are not related to specific system calls and are common to all system calls, and then calls specific kernel functions according to the system call number. After returning from the kernel function used to realize the specific system call, some code assistants in the system call mechanism (via the iret instruction) prepare to return to the user state.

Abstract

The invention relates to a method for realizing a Windows system call simulation mechanism in a Linux kernel. The method comprises the following steps of: 1) modifying the code of the Linux kernel and keeping interrupt vectors within a range from 0x20 to 0x2f so that the Linux kernel cannot distribute the interrupt vector 0x2e for external interruption; and 2) transplanting the code of the Windows system call simulation mechanism realized in ReactorOS into the Linux kernel, and performing necessary modification as required. The method has the advantages that: the Windows system call simulation mechanism based on an int0x2e instruction is realized in the Linux kernel, and the primary requirement that the Linux kernel supports the Windows application is met.

Description

technical field [0001] The invention relates to the field of computer operating systems, in particular to a method for realizing a Windows imitation system call mechanism in a Linux kernel. Background technique [0002] The operating system is equivalent to the soul of the computer. Any computer is inseparable from the operating system, and is also limited by the operating system. All application software is based on a specific operating system and can only run on this specific operating system. If it runs on other operating systems, it cannot run. The core of the operating system is called the "kernel". The kernel provides the application software with a specific operating environment and basic operating capabilities. The calls of the application software to these basic operating capabilities are called "system calls." Although the basic operating capabilities provided by different operating systems are generally quite similar, the system calls and their collections provid...
