Abstract

Embodiments of the present disclosure relate to a method, device and computer program product for kernel management. The method comprises: receiving, from a server, a plurality of instances of a kernel module to be loaded into a kernel, the plurality of instances corresponding to a plurality of candidate versions, determining a current version of the kernel in response to the kernel being started or updated, and loading, to the kernel, an instance of the plurality of instances corresponding to the current version. Embodiments of the present disclosure may improve the security of the operating system, meet close-source requirement of a commercial operating system and also simplify the process of the kernel module referring to one or more APIs.

Claims

1. A method of kernel management, comprising:

receiving, from a server, a plurality of instances of a kernel module to be loaded into a kernel, the plurality of instances corresponding to a plurality of candidate versions;

determining a current version of the kernel in response to the kernel being started or updated; and

loading, to the kernel, an instance of the plurality of instances corresponding to the current version.

2. The method according to claim 1, wherein the loading comprises:

updating an application programming interface (API) table of the kernel module,

wherein the API table comprises an address, in the kernel, of an API used by the kernel module.

3. The method according to claim 2, wherein the API table further comprises a second address, in the kernel, of a second API used by a second kernel module loaded to the kernel.

4. The method according to claim 1, wherein the plurality of candidate versions correspond to a plurality of universal versions of the kernel, and the plurality of universal versions comprise the current version.

5. The method according to claim 1, wherein the plurality of candidate versions are each encapsulated in a binary code.

6. A method of kernel management, comprising:

generating a plurality of instances of a kernel module to be loaded into a kernel, the plurality of instances corresponding to a plurality of candidate versions;

transmitting the plurality of instances to the client; and

receiving a loading result from the client.

7. The method according to claim 6, wherein the generating comprises:

generating an application programming interface (API) table of the kernel module,

wherein the API table comprises an address, in the kernel, of an API used by the kernel module.

8. The method according to claim 6, wherein the plurality of candidate versions correspond to a plurality of universal versions of the kernel of the client.

9. The method according to claim 6, wherein the plurality of candidate versions are each encapsulated in a binary code.

10. An electronic device, comprising:

at least one processing unit; and

at least one memory coupled to the at least one processing unit and storing machine-executable instructions, the instructions, when executed by the at least one processing unit, causing the electronic device to perform a method, the method, comprising;

receiving, from a server, a plurality of instances of a kernel module to be loaded into a kernel, the plurality of instances corresponding to a plurality of candidate versions;

determining a current version of the kernel in response to the kernel being started or updated; and

loading an instance of the plurality of instances corresponding to the current version to the kernel.

11. The device according to claim 10, wherein the loading comprises:

updating an application programming interface (API) table of the kernel module,

wherein the API table contains an address, in the kernel, of API used by the kernel module.

12. The device according to claim 11, wherein the API table further a second address, in the kernel, of a second API used by a second kernel module loaded to the kernel.

13. The device according to claim 10, wherein the plurality of candidate versions correspond to a plurality of universal versions of the kernel and the plurality of universal versions comprise the current version.

14. The device according to claim 10, wherein the plurality of candidate versions are each encapsulated kernel module binary codes respectively.
