摘要： Embodiments of the present invention disclose a resource leak detection method, apparatus, and system. The method includes: obtaining a target resource called when target code of a program runs, where the target code is partial code in program code; determining a first storage resource amount occupied by the target resource; determining whether the first storage resource amount occupied by the target resource satisfies a first preset condition; and if the first storage resource amount occupied by the target resource satisfies the first preset condition, determining a storage location of the target code as a resource leak location. In the embodiments of the present invention, the target code of the program can be tracked, and further, by means of detection, the storage location of the target code can be determined as the resource leak location. It is unnecessary to track all resource allocation and release, thereby reducing performance overheads and improving resource leak detection efficiency.
摘要翻译：本发明的实施例公开了资源泄漏检测方法，装置和系统。该方法包括：获取程序目标代码运行时调用的目标资源，目标代码为程序代码中的部分代码; 确定目标资源占用的第一存储资源量; 判断目标资源占用的第一存储资源量是否满足第一预设条件; 若所述目标资源占用的第一存储资源量满足所述第一预设条件，则确定所述目标代码的存储位置为资源泄漏位置。在本发明的实施例中，可以跟踪程序的目标代码，并且进一步通过检测可以将目标代码的存储位置确定为资源泄漏位置。无需跟踪所有的资源分配和释放，从而降低了性能开销并提高了资源泄漏检测效率。

摘要： 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 (S202). 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, time consumed for labeling the stored resource can be reduced. This improves labeling efficiency, reduces time consumed for the system software version upgrade, and improves efficiency of the system software version upgrade.

摘要： Embodiments of the present invention relate to a kernel integrity protection method and apparatus, and the method includes: sending, by a first processing module running in a first running space, a request message to a second processing module running in a second running space, where the request message is used to request to perform memory access, and the memory access relates to preset register access and/or preset memory space access; in response to the request message, obtaining, by the second processing module running in the second running space, information about an event corresponding to the memory access, sending the information to the first processing module running in the first running space; and processing, by the first processing module running in the first running space, the event based on the information. This can dynamically measure kernel integrity and terminate an intrusion in real time.
