Problems solved by technology

[0007] Because programmers are often confident enough in their own programs, the test cycle is short, while the function and correctness tests of device drivers often depend on specific hardware, the test cycle is short, and there are few test scenarios. They only care about function realization without too much Consider related functional tests such as system environment configuration

Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] The present invention provides a log injection-based driver configuration debugging method, including:

[0027] S1. Extract configuration specification documents such as device registers of the driver;

[0028] S2. Perform detection hook injection on the driver according to the driver configuration document;

[0029] S3. Add a relevant type of log function at the detection hook position;

[0030] S4. Run the modified driver, and dynamically monitor the operation of the driver during runtime. When a configuration exception occurs, it can catch the exception in time, and automatically handle some errors. For the exception that cannot be handled, submit the log to th...

Abstract

The invention discloses a drive configuration debugging method based on log injection. The method includes S1, extracting configured specification documents of a drive device register; S2, performing detection hook injection on a drive according to the configured specification documents; S3, adding log functions in relevant types to positions of detection hooks; S4, operating the modified drive, and monitoring the operation of the drive dynamically during operation. The drive configuration debugging method based on the log injection has the advantages that checking codes can be inserted in the drive according to the requirements of the configured documents, configuring parameters in drive configuration can be detected dynamically during operation, errors can be recorded and processed when the errors occur, and reliability of the drive can be improved accordingly.

Description

technical field [0001] The invention relates to the technical field of computer security protection, in particular to a log injection-based driver configuration debugging method. Background technique [0002] In the current general-purpose operating system, drivers are often loaded into the kernel in the form of modules to run, and call a large number of kernel extensions. In Linux, the driver occupies 70% of the code of the operating system, and causes 3-7 times more errors than the kernel code. In Windows, it is also reported that 85% of system crashes are related to driver errors. [0003] Drivers run in the form of kernel extensions, and most of them run in the kernel state, so the reliability of the driver is very important to the system. However, since driver development is often separated from system development, slight changes in kernel extension functions may cause driver instability. In addition, many driver developers violate the usage specification of kernel ex...
