Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of a dual-system secure mobile phone resetting method according to an embodiment of the present invention, where the method is applicable to a case of quickly resetting one of the systems in the dual-system secure mobile phone, and the method may be executed by a dual-system secure mobile phone resetting device and correspondingly set in a terminal of the dual-system secure mobile phone, and specifically includes the following steps:
and 110, restarting a container corresponding to the reset operation, and generating a restart modification sub-process by using the init process.
An exemplary dual-system mobile phone may be implemented by using a container technology, and fig. 2 is a schematic diagram of dual-system secure mobile phone architecture in a dual-system secure mobile phone resetting method according to an embodiment of the present invention, referring to fig. 2, where the dual-system secure mobile phone includes: the lean Linux system (basic platform) is used for bottom hardware and corresponding driving, and provides a corresponding hardware foundation for the double systems. While the dual system is implemented by container technology, LXC (Linux Container) technology is exemplary. LXCs can provide lightweight virtualization to isolate processes and resources, and do not need to provide instruction interpretation mechanisms and other complexities of full virtualization. The LXC can realize hardware control of the basic platform by means of hardware driving of the basic platform.
In this embodiment, the user may reset the system corresponding to LXC through the operation, that is, restore the factory setting operation.
And restarting the container corresponding to the factory setting restoration operation when receiving the reset operation. Illustratively, at startup, the restart modification sub-process is generated by utilizing the init process of the lean Linux system. The init process is one of the programs indispensable in the operation of the Linux system, and is a user-level process started by the kernel.
Because the restarting container is required to be controlled, a corresponding process is required to be implanted into the Linux system after the weight is reduced to realize the purpose of controlling the restarting container. Because only the drive of hardware is provided in the Linux system after slimming, a hardware foundation is provided for the LXC. Therefore, the number of processes is small, and only init processes exist in the processes which can survive in the normal period of the Linux system after weight reduction. Thus, the init process may be utilized to generate a restart modification sub-process, which may be utilized to implement the adjustment and control of the system in the LXC container.
In this embodiment, there are three systems. And the reset corresponds to only one of the systems, therefore, firstly, the init process corresponding to the restarting system and the init. Rc file of the reset container need to be determined. Since the restart system is implemented using LXC containers, it is necessary to determine the init process of the reset container and the init. Rc file of the reset container. For example, the init process of the reset container and the init. Rc file of the reset container may be determined by corresponding reference numerals, or generation times.
And 130, modifying the file mounting part in the main function of the init.rc file of the reset container by utilizing a restarting modification subprocess so as to point to the corresponding data file of the corresponding reset.
init.rc is based on AIL (Android Init Language) being a very simple language, mainly used to define what needs to be done in the initialization procedure. Main functions are arranged in init.rc, and mainly comprise five types of sentences: action, command, service, option, import. Options are an option for Service, used in conjunction with Service. In which a corresponding data file may be defined. For example, the data file corresponding to the overlay may be loaded using a chown < owner > < group > < path > option statement. Wherein chown is used to change the genus owner and/or genus group of each file. In this embodiment, the method may be defined as a generic group of the container, and the path for resetting the corresponding data file is written into the corresponding < path >, and the corresponding service is started with an on flag.
After the container is started, a corresponding mirror image needs to be loaded, and the mirror image can be the mirror image when the container exits last time.
And step 150, adjusting the init process of the reset container by utilizing a restarting modification subprocess so that the init process directly jumps to the file mounting part recorded in the guiding init.rc script to run.
Normally, the init process usually only needs to remain alive all the time, without any adjustments, since the previous image has been loaded. In this embodiment, however, the file data is changed, and the init. Therefore, the init process needs to be adjusted to register file data in main functions in the init. Rc script. Because the loading mirror image method is adopted, the hardware driver part is loaded, and the init process does not need to reload the hardware driver and only needs to re-register the corresponding data file. Therefore, the init process of the reset container can be controlled by utilizing the restarting modification subprocess, the hardware driving part is skipped to be loaded, and the operation is directly skipped to the operation script of the file mounting part recorded in the guide init.
In the embodiment, the restart modification subprocess is generated by utilizing the init process through restarting the container corresponding to the reset operation; determining an init process of the reset container and an init. Rc file of the reset container; modifying a file mount part in a main function of an init.rc file of the reset container by utilizing a restarting modification subprocess so as to point to a corresponding data file for resetting; loading a mirror image of the container at the previous exit; and adjusting the init process of the reset container by utilizing a restarting modification subprocess so that the init process directly jumps to the file mounting part in the guiding init. Rc script to run. The interference capability of the host machine to the container is fully utilized, and the restarting modification subprocess is generated by utilizing the kernel process of the host machine. The init.rc script of the container which needs to be subjected to system reset is modified, corresponding mounted file data are adjusted, and the init process corresponding to the container is adjusted, so that the init script is directly jumped to the recorded file mounting part in the guided init.rc script to run, and the corresponding hardware mounting part is not required to be reconfigured, so that the erasing process of the data file is saved in the resetting operation, the hardware driving is not required to be mounted again, the system resetting time corresponding to the container is greatly saved, and the user experience of resetting by using the dual-system mobile phone is improved.
In a preferred implementation of this embodiment, the method may further comprise the steps of: and adding factory setting restoration broadcasting service in the container system by restarting the modification subprocess, broadcasting factory setting restoration information, and enabling the android system to clear the memory content. Because the mobile phone service is provided by adopting a container loading mirror image mode, some active processes including a system process and an application process exist in the loaded mirror image, and the situation of occupying original user data exists in the processes. At this time, a sub-process can be derived from the init process in the container system by restarting the modification sub-process, and is used for providing corresponding broadcasting service, broadcasting all processes in the container system, broadcasting corresponding factory setting information, so that the corresponding processes clear the memory content, and avoiding the read-write errors of the system.

The original data file system comprises the following steps: and (3) clearing folders such as/data,/cache,/metadata and the like, and resetting user data in the current system.
And 230, closing the container corresponding to the container code.
And closing the container corresponding to the container code, so as to facilitate the later restarting and realize the recovery of the system from factory setting.
And step 270, adjusting the init process of the reset container by utilizing the restarting modification subprocess, so that the init process directly jumps to the file mounting part recorded in the guiding init.rc script to run.

When receiving the reset operation, the container system corresponding to the reset operation is definitely determined, so that the interference of the reset to other systems is avoided, and the user data file needing to restore the factory setting can be correctly selected.
In a preferred implementation of this embodiment, after closing the container corresponding to the container code, the method may further comprise the steps of: and distinguishing and isolating the user data of the current system by using a naming space. Namespace is a "namespace," also known as "namespace. Is a form of code organization used by many programming languages, categorized by namespace. The user data of the current system can be effectively distinguished from other user data by using the naming space.
In another preferred implementation of the present embodiment, the method may further comprise the steps of: and dividing the resources of the restarted container by using the Cgroup according to the resources of the container when the container exits last time, so that the Cgroup consistent with the resources of the container exits last time can refer to a specific process group. The Cgroup is a mechanism for managing processes according to groups in Linux, and in the user plane, the Cgroup technology can organize all processes in each system into an independent tree, each tree contains all processes of the system, and each node of the tree is a process group. Through the Cgroup mechanism, all processes when the container exits last time can be determined, and corresponding resources can be determined. The resources required by various processes can be correspondingly set, and the resources after the container is started can be kept consistent. Avoiding the occurrence of system errors.
