Abstract: An electronic device includes a memory and at least one processor coupled to the memory. The at least one processor is configured to identify a device change event in a host operating system, wherein the host operating system includes a host namespace, switch from the host namespace to a container namespace of a container, and update the container with information based on the device change event.

Abstract: A method for operating an electronic device, the method including spawning a name space tool (NST) as part of a boot process of a host OS, wherein the NST is a process with a plurality of root privileges of the host OS. The method further includes spawning, by the NST, a container for a guest OS, wherein the container for the guest OS is mapped to a dedicated domain in the host OS, and dropping, by the NST, a root privilege of the host OS in response to spawning the container for the guest OS.

Abstract: This disclosure relates to an electronic device including a memory and at least one processor coupled to the memory. The at least one processor is configured to execute a daemon process in one of a container or a host operating system, wherein the daemon process is configured to manage data transfer between the container and the host operating system, create, via the daemon process, an inter-process communication (IPC) channel between the container and the host operating system, receive incoming audio data, and buffer the incoming audio data to the IPC channel.

Abstract: A method for implementing a shared memory buffer includes at an apparatus comprising a processor and a physical memory, running a host environment with a host virtual memory. The method further includes running a guest environment with a guest virtual memory, performing, by the host environment, an allocation of a frame buffer in the physical memory, and mapping the allocated frame buffer into the host virtual memory. Additionally, the method includes passing a handle of the allocated frame buffer to the guest environment and performing a mapping of the allocated frame buffer into the guest virtual memory, the mapping based on the handle of the allocated frame buffer.

Abstract: An apparatus and method for protecting kernel data integrity in an electronic device are provided. The method includes mapping a specified type of data to a read-only memory area, detecting a write attempt to the specified type of data, determining whether a process attempting to write to the specified type of data is permitted according to a specified condition, and allowing the write attempt if the process attempting to write to the specified type of data satisfies the specified condition.
