Problems solved by technology

[0003] In this way, when the NFS client performs permission setting on the file again, because the NFS client can only set the read-out and write permissions of the file, but cannot set the extended permission of the file, the NFS client is aimed at the file. The permission settings of the file will overwrite the permission settings made by other clients on the file, which will cause the loss of the extended permissions set by other clients for the file, thereby affecting the use of the file by other clients

Embodiment Construction

[0039] In the existing distributed file system, the NFS server can only support standard POSIX ACL permissions, that is, the NFS server can only support the NFS client to set the read and / or write permissions for files in the file system. However, in some practical application scenarios, the private client in the distributed system may set some extended permissions on the file, such as delete permissions. When the NFS client sets read and / or write permissions for the file, since the NFS client cannot set extended permissions, the permissions set by NFS for the file override those set by other clients for the file. The setting of the extended permission is performed, so that the extended permission set by other clients for the file is lost, thereby affecting the use of the file by other clients.

[0040]In order to solve the above technical problems, the embodiment of the present application provides an extension method of access control authority, by splicing the extended auth...

Abstract

The present application discloses a method and device for extending the access control rights. The method includes the following steps of using the NFS server end to obtain the first permission information set in advance for the target file in response to the permission setting request sent by the NFS client end for the target file, wherein, the NFS client end and the NFS server end perform data communication based on the NFS protocol; detecting whether the first right contains extended right information, if it is determined that the first right contains extended right information, splicing the extended right information with the second right information sent by the NFS client, obtaining the first target right information, and using the first target right information to set the access control right for the target file, so that by splicing the extended permission information of the target file and the first permission information sent by the NFS client, the problem that the extended permission of the target file is lost after the NFS client sets the permission for the target file is avoided.

Description

technical field [0001] The present application relates to the technical field of rights extension, in particular to a method and device for extending access control rights. Background technique [0002] In a distributed file system, it is a common way for a client to access the file system based on the NFS (Network File System, network file system) protocol. Usually, the NFS client can set the standard POSIX (Portable Operating System Interface of UNIX, portable operating system interface) ACL (Access Control List, access control list) permission on the file in the file system through the NFS server. The POSIX ACL permissions only include read and write permissions for the file. However, in some application scenarios, other clients (such as private clients) in the distributed system may set some extended permissions on the file, such as delete permissions for the file, etc., so that the file is in the Along with read and write permissions, it has extended permissions such ...
