Method for Multiplexing Binder IPC Mechanism in Multiple Android Systems in Mobile Virtualization Scenario

Abstract

The invention discloses a method for multiplexing Binder IPC mechanisms in multiple Android systems in a mobile virtualization scene. The method includes: creating a virtual Binder device driver in the Android system in the host machine, and using the virtual Binder device driver to drive to the Linux kernel. Register multiple virtual binder devices, and assign the device files corresponding to the virtual binder devices to each virtual machine; when a virtual machine sends an access request for a binder device, it first calls the virtual binder device driver, and then forwards the usage request to The real Binder device driver; during the process of forwarding the operation to the real Binder device by the virtual Binder device driver, intercept, filter and modify the conflicting service name accordingly. The present invention ensures the high efficiency of system performance under the realization of multi-Android system operation.

Description

technical field [0001] The invention relates to the technical field of computer virtualization, in particular to a method for multiple systems multiplexing Binder IPC mechanism in Android system virtualization. Background technique [0002] In the context of the rapid growth of the number of users of the Android operating system, its security has also received more and more attention. Since Android lacks a closed ecosystem like iOS, malware has become the biggest threat to its security. In order to limit the scope of activities of malicious software and protect users' personal information to the greatest extent, someone proposed a solution of Android virtualization. Android virtualization refers to running multiple Android operating systems on one device. These operating systems are isolated from each other, and the application software installed in one system cannot affect other systems. In this way, the user's personal information can be blocked in a certain system, even...

Problems solved by technology

This solution either requires a large-scale modification of the original Binder device driver, which is not conducive to the stability of the system; or it needs to create multiple peer-to-peer Binder device drivers in the kernel, and this design lacks flexibility.

[0008] 2) Since the client in each system can only access the Binder device inside its own system, these client processes can only use the services running in the system, so that the sharing of services between systems cannot be realized, that is, it cannot be reduced The total number of services running on the entire device, which is not conducive to optimizing the operating performance of the device

[0009] Therefore, a method that is more convenient and has a lower impact on performance is needed to solve the problems of Binder device virtualization and service sharing. For this reason, the present invention designs a method for a virtual machine to reuse the Binder IPC mechanism of the host machine
