Abstract: An application program launching method and a system for improving security of an embedded Linux kernel are provided to execute the application program processor in the manner in which each application program processor is executed by a respective user, so that the embedded Linux system can be configured using conventional Linux system security functions. An application program launching method comprises the following several steps. An application program is installed(501), and t user selects an application program to be launched(502). A registry interface searches security set information on the selected application program from the registry through a registry manager, wherein the security set information includes a user ID associated with the selected application program, a capability, and a basic directory(503). A controller changes a user account for an application program processor to the user ID in the security set information(504). The application launching processor determines whether or not the application program processor is a system management processor(505). If the application program processor is a system management processor, since the application program processor needs part of the super-user privileges, the controller sets the capability based on the setting information for the capability in the security set information(506). The controller changes a basic directory of the application program processor according to the basic directory in the security set information(507). The controller launches the application program(508).

A method for automatically testing an embedded system software comprises the following several steps. An event management engine sets up a test environment at a target system(S610). The event management engine accesses an event agent of the target environment(S620). The event agent reads a test event stored at an event & message repository of a host system, and execute the event by a scheme that a signal generated when there occurs the event is inputted to an equipment driver(S630), and then storing a message, generated at a test program installed at a target system, at the event & message repository of the host system(S640). If all the events are determined to be completed(S650), a result message stored together when the host system constructs a scenario is compared with a message generated by the test program after the target system executes the scenario(S660).

Abstract: A method and an apparatus for managing out-of-memory in an embedded system are provided to provide a flexible algorithm for processing the out-of-memory according to a memory usage behavior of an application program. A method for managing out-of-memory comprises the following several steps. A user sets an available memory threshold and an out-of-memory management policy including an out-of memory algorithm and a protection process selection via a policy setup module, and registers the set memory management policy at an operating system(S320). If a new process requests memory assignment during system operation(S330), a management apparatus checks an available memory by using the inputted available memory threshold(S340). If the threshold of the available memory is larger than a requested memory amount of the new process, the apparatus assigns the requested memory to the new process(S345). If the threshold of the available memory is smaller than a requested memory amount of the new process, the apparatus recognizes the out-of-memory and executes the out-of-memory management algorithm(S350). The apparatus selects a sacrifice process according to the selected out-of-memory management algorithm(S360). The apparatus terminates the selected sacrifice process and gets back the memory used by the sacrifice process(S370), and checks the available memory.
