Patent number: 11222118Abstract: A method for updating a SELinux security policy and a terminal. The method includes receiving, by the terminal, a security policy file sent by a server. The method further includes, performing, by the terminal in a power-on status, storing the security policy file in preset storage space by using a first service or process, modifying, by the terminal, a value of a preset attribute value from a first value to a second value by using the first service or process, reading, when it is detected that the value of the preset attribute value is changed from the first value to the second value, the security policy file from the preset storage space by using a second service or process and writing the security policy file into a memory, and loading, by the terminal, the security policy file in the memory by using the second service or process.Type: GrantFiled: October 30, 2017Date of Patent: January 11, 2022Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Dengzhou Xia, Fuzhou Xiao, Li Chen

Publication number: 20210081217Abstract: A resource permission processing method and apparatus, a storage medium, and a chip are disclosed, to update a resource label in a terminal device based on a first resource permission configuration file when a system software version in the terminal device is upgraded. The first resource permission configuration file covers only path information in which a label changes before and after the system software version is upgraded. Therefore, in a process of updating the resource label stored in the terminal device, a matching amount is greatly reduced when path information that matches traversal path information of a resource is searched for in the first resource permission configuration file, and therefore time consumed for labeling the stored resource can be reduced. The reduced time for labeling the stored resource improves labeling efficiency, reduces time consumed for the system software version upgrade, and improves efficiency of the system software version upgrade.Type: ApplicationFiled: March 27, 2018Publication date: March 18, 2021Inventors: Fuzhou XIAO, Youzhan YIN, Li CHEN
