Abstract

The present invention provides a method and a computation node for processing application data. The method includes: starting, by an operating system, a service process; establishing, by the operating system, a socket connection between the service process and backup software, where the service process has a root operation right, and the service process and the backup software have the same user identifier; sending, by the backup software through the socket, a processing request for application data; receiving, by the service process through the socket, the processing request for application data, where the processing request is sent by the backup software, sending the processing request for application data to corresponding application software, receiving application data returned by the corresponding application software, and sending the returned application data to the backup software through the socket.

in response to determining that the root operation right and the provider interface are not provided;

starting, by the operating system, the service process;

setting the root operation right of the service process;

establishing, by the operating system, a socket connection between the service process and the backup software, wherein the service process has the root operation right;

setting a user identifier (uid) for the service process and the backup software to the same user identifier;

performing a signature verification on a processing request;

sending, by the backup software through the socket, a length of the processing request for application data after the signature verification passes;

determining, based on the length of the processing request, a specific content for the application data;

sending, by the backup software through the socket, the specific content;

receiving, by the service process through the socket, the processing request for application data, wherein the processing request is sent by the backup software;

sending, by the service process, the processing request for application data to corresponding application software;

receiving, by the service process, application data returned by the corresponding application software, wherein the application data is application data returned in response to the processing request; and

sending, by the service process through the socket, the returned application data to the backup software.

2. The method according to claim 1, wherein the sending, by the service process through the socket, the returned application data to the backup software specifically comprises:

sending, by the service process through the socket, a length of the returned application data to the backup software; and

sending, by the service process through the socket, specific content of the returned application data to the backup software.

3. The method according to claim 2, wherein the processing request for application data comprises a catalogue reading request or a file reading request, and accordingly, the application data returned by the corresponding application software comprises catalogue information that is read or file content that is read.

4. The method according to claim 2, wherein the processing request for application data comprises a catalogue writing request or a file writing request, and accordingly, the application data returned by the corresponding application software comprises a result corresponding to the catalogue writing request or a result corresponding to the file writing request.

5. The method according to claim 1, wherein the sending, by the service process through the socket, the returned application data to the backup software specifically comprises:

sending, by the service process through the socket, a length of the returned application data to the backup software; and

sending, by the service process through the socket, specific content of the returned application data to the backup software.

6. The method according to claim 5, wherein the processing request for application data comprises a catalogue reading request or a file reading request, and accordingly, the application data returned by the corresponding application software comprises catalogue information that is read or file content that is read.

7. The method according to claim 5, wherein the processing request for application data comprises a catalogue writing request or a file writing request, and accordingly, the application data returned by the corresponding application software comprises a result corresponding to the catalogue writing request or a result corresponding to the file writing request.

8. The method according to claim 1, wherein the processing request for application data comprises a catalogue reading request or a file reading request, and accordingly, the application data returned by the corresponding application software comprises catalogue information that is read or file content that is read.

9. The method according to claim 1, wherein the processing request for application data comprises a catalogue reading request or a file reading request, and accordingly, the application data returned by the corresponding application software comprises catalogue information that is read or file content that is read.

10. The method according to claim 1, wherein the processing request for application data comprises a catalogue writing request or a file writing request, and accordingly, the application data returned by the corresponding application software comprises a result corresponding to the catalogue writing request or a result corresponding to the file writing request.

11. The method according to claim 1, wherein the processing request for application data comprises a catalogue writing request or a file writing request, and accordingly, the application data returned by the corresponding application software comprises a result corresponding to the catalogue writing request or a result corresponding to the file writing request.

12. The method according to claim 1, wherein the sending, by the service process, the processing request for application data to the corresponding application software specifically comprises:

performing, by the service process, the signature verification on the processing request; and

if the signature verification is passed, sending the processing request for application data to the corresponding application software.

13. A mobile computation node, comprising a hardware layer, an operating system operating on the hardware layer, wherein the mobile computation node comprising:
