Embodiment Construction

[0045] The embodiment of the present invention provides a Linux-based server program fault injection method, device and system, which solves the problem that the current fault injection is usually static injection, and there is a technology that cannot detect possible faults that may occur during the operation of the underlying software. question.

[0046] Hook technology is a platform of Windows message processing mechanism, on which an application program can set a subroutine to monitor certain messages of a specified window, and the monitored window can be created by other processes. When the message arrives, process it before the target window handler. The hook mechanism allows applications to intercept and process window messages or specific events. A hook is actually a program segment for processing messages, which is hooked into the system through system calls. Whenever a specific message is sent, before reaching the destination window, the hook program first captures...

Abstract

The embodiment of the invention discloses a method, an apparatus and a system for performing server program fault injection based on Linux, which solve a technical problem that the present fault injection generally is static injection and cannot detect faults possibly generated in a running process of software in a bottom player. In the embodiment of the invention, the method for performing server program fault injection based on Linux comprises the following steps of: determining a to-be-injected process of a target host; analyzing the to-be-injected process through a Hook technology, determining an objective function and performing injection function substitution; performing preset fault type injection for the to-be-injected process withthe injection function substituted; and acquiring a process running result after preset fault type injection.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method, device and system for fault injection of server programs based on Linux. Background technique [0002] Fault injection is a reliability verification technique that deliberately introduces faults into a system through controlled experiments and observes the behavior of the system in the presence of faults. Software-based fault injection creates faults at the hardware level by generating errors at the software level. There are many injection methods, such as modifying memory data, generating faults through application software or generating faults through underlying software such as operating systems. There are many injection methods, such as modifying memory data, generating faults through application software or generating faults through underlying software such as operating systems. In addition, the effect of fault injection can be achieved by changing the logic va...
