Instrumenting system calls in a source process executable
A recently granted patent (Publication Number: US11868781B2) discloses a computer-implemented method for instrumenting a source process. The method involves identifying a system call from a source process executable, building a trampoline for the system call, overwriting the system call with jump instructions, and executing the source process with the trampoline to instrument the system call. The trampoline includes areas for invoking a handler, executing a relocated copy of the system call, and returning flow to the original address. Additionally, the method includes identifying relocatable instructions, setting flags, and reporting results to a user device.
Furthermore, the patent describes the process of identifying function calls, building trampolines for different types of calls, and collecting results associated with instrumenting the system calls. The method also involves writing jump instructions in unused spaces of the source process executable and ensuring the code length of the jump instructions align with the system call's code length. By utilizing trampolines and jump instructions, the method allows for efficient instrumentation of system calls in source processes, enhancing the monitoring and control capabilities of computer systems.
