Abstract

The invention discloses a LINUX kernel reliability evaluating system based on source code analysis. The LINUX kernel reliability evaluating system comprises a master control end and an object end, wherein the master control end runs in an independent system, and comprises a control module with control logics, a fault injector module, a communication module, a fault load generator module and a data analysis module; and the object end comprises an injection actuator module, a work load generator module and a result collecting and performance monitoring module. Evaluating errors generated by the traditional method can be avoided effectively, analog internal memory mistakes are injected in a kernel of an object operating system, response of the object system to injected fault is observed, experiment information is collected, the collected experiment information is counted and analyzed, an experiment process of a relevant result is provided for a user, fault injection success rate and fault coverage rate are increased, detection coverage rate and recovery coverage rate of the system are monitored accurately, and accurate evaluation reliability of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of LINUX system reliability evaluation, and relates to a source code analysis-based LINUX kernel reliability evaluation system and a method thereof. Background technique [0002] In a computer system, the operating system is one of the most important and sensitive components. It interacts with the hardware to provide basic services for applications and manage all resources of the computer. The execution of all applications depends on the correct operation of the operating system, so the accurate operation of the operating system is very important. Errors within the operating system can easily propagate up to the application and down to the hardware, causing the system to fail. Any operational disturbance may eventually cause loss of production capacity or economy, so the stable operation of the operating system is very important. [0003] At present, the methods of system reliability evaluation mainly incl...
