Abstract: Embodiments of the present disclosure relate to a method, system, and computer program product for dynamic update of a computer program in memory. According to the method, one or more processors obtain incremental information, the incremental information specifying an incremental update to at least one section of at least one target function in a computer program. One or more processors identify, based on the incremental information, the at least one target function to be updated from the computer program. One or more processors generate at least one updated copy of the at least one target function by updating the at least one section of the at least one target function based on the incremental information. One or more processors update the computer program based on the at least one updated copy of the at least one target function while the computer program is running.

Abstract: A computer-implemented method, computer program product and computer system are provided. A processor receives an indication of sensitive data in one or more files. A processor updates at least one bit in the virtual address space for the one or more files indicated to have sensitive data. A processor, in response to a program accessing the one or more files, evaluates a respective virtual address for the one or more files. A processor, in response to the at least one bit in the respective virtual address for the one or more files, marks intermediate data generated by the program as sensitive data.

Abstract: Determination and provision of improved representations of program flow control are provided by a method that monitors execution of binary code of a program on a computer system. The monitoring includes monitoring manipulation(s) of call stack(s) maintained by the computer system for the execution of the binary code. The method, based on the monitoring, determines function call pattern(s) and branch pattern(s) exhibited by the execution of the binary code. The method identifies, from the binary code and using the determined function call pattern(s) and branch pattern(s), function calls and branches, relations between the function calls and branches, and function and variable names. The method also provides a representation of program flow control of the program using the identified function calls and branches, relations, and function and variable names.

Abstract: Aspects of the invention include computer-implemented method that includes generating a preliminary control flow graph from memory dump data and compiler listing data in response to an exception event at a computing program. Code segments associated with each block of the preliminary control flow graph are translated to Boolean statements. Each Boolean statement is determined to be either satisfied or unsatisfied based on input values retrieved from the memory dump data. An edge property value of a first edge and a second edge of a plurality of edges of the preliminary control flow graph based are calculated based on a satisfaction of the Boolean statements. The edge property value of the first edge is compared to the edge property value of the second edge. The preliminary control flow graph is refined by deleting the first edge of the plurality of edges based at least in part on the comparison.

Abstract: A server motherboard diagnosis method, system, and related circuit system. A management module of the server motherboard and peripheral devices managed by the management module are capable of being powered by a server power source and a USB port. In response to the management module and the peripheral devices being powered by the USB port, a power supply line of the server power source is isolated, as by: identifying the peripheral devices, in response to the management module and the peripheral devices being powered by the USB port; for each of the identified peripheral devices, initializing the peripheral device, and then shutting down the power supply of the peripheral device; establishing a communication between the management module and a diagnosis host through the USB port; and executing a command in response to the command being received from the diagnosis host.
