Method and device for loading kernel module

Abstract

The invention discloses a method and device for loading a kernel module. The method comprises the specific steps that a response to a loading operation for loading the kernel module to be loaded to a target kernel is made, and feature information of the target kernel is acquired; based on the feature information, loading information corresponding to the kernel module to be loaded is configured; based on the loading information, the kernel module to be loaded is loaded into the target kernel. When the kernel module needs to be loaded to the target kernel, kernel version parameters, kernel symbol verifying parameters, kernel module loading function pointers, kernel module unloading function pointers and other loading information in an ELF file corresponding to the kernel module are directly modified, the loading information is suitable for verification of the target kernel, and the kernel module can be loaded into the target kernel. Under the condition that the kernel module does not need to be recompiled, the kernel modules are loaded into kernels of different versions, the applicability of the kernel module is enhanced, and the development cost is reduced.

Description

technical field [0001] The present application relates to the field of computers, in particular to the field of operating systems, and in particular to a kernel module loading method and device. Background technique [0002] In the development of a kernel program, it is usually necessary to generate a kernel module containing the source code of the kernel program, and then load the kernel module into the kernel, so that the kernel program can run in the kernel. At present, when the kernel module is loaded into the kernel, the usual way is to configure the parameters to be verified by the kernel during the loading process of the kernel module in the kernel module, and then recompile the kernel module and load it into the kernel. [0003] However, due to the diversity of kernel versions, the parameters that need to be verified by the kernel in a kernel module loaded on one version of the kernel are fixed, so that the kernel module can only be loaded on one version of the kerne...

Problems solved by technology

[0003] However, due to the diversity of kernel versions, the parameters that need to be verified by the kernel in a kernel module loaded on one version of the kernel are fixed, so that the kernel module can only be loaded on one version of the kernel, making the kernel module Applicability is limited, increasing development costs
