Abstract

The embodiment of the invention provides a user program running method, system, device and equipment and a storage medium, and the method comprises the steps: responding to a kernel mode running operation of a user program, and obtaining a machine code file and a to-be-detected function corresponding to the user program through a hook function in an operating system; and then, responding to the execution operation of the kernel in the operating system on the to-be-detected function, writing the machine code file corresponding to the user program into a preset detection framework deployed by the kernel so as to obtain a kernel module, and enabling the user program to run in a kernel mode of the operating system by utilizing the kernel module. According to the method, the kernel module used for executing the user program can be generated in real time in a file writing mode, so that for the kernel without the kernel module preset, the user program can run in the kernel under the condition that the user program is not modified, and the user program can run in the kernel without being modified. And the user program can normally run in the kernel mode of the operating system.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a user program running method, system, device, equipment and storage medium. Background technique [0002] Linux is a UNIX-like operating system that is free to use and spread freely. User programs installed in the Linux operating system, such as eBPF programs, can run in the user mode or kernel mode of the operating system. And with the upgrade of the kernel version in the Linux operating system, since the corresponding kernel module will be pre-deployed in the high-version kernel, this kernel module can be directly used to make the eBPF program run in the kernel state of the operating system, that is, to use eBPF programs run on higher version kernels. [0003] However, for operating systems deployed with lower-version kernels, eBPF programs cannot run in the kernel mode of the operating system, that is, eBPF programs cannot run in lower-version kernels. At this po...
