Dynamic Library Executor

Adrian & Alexandru Ariton 323CA

This program is designed to execute functions from dynamic libraries (shared objects) in a controlled environment. It communicates with a client over a socket, receives commands specifying the library, function, and parameters, and executes the requested function.

Features

  • Executes functions from dynamic libraries based on client commands.
  • Limits the runtime of the executed function to prevent indefinite execution.
  • Cleans up resources and handles timeouts gracefully.
  • The execution is limited to a specified time, and the program handles cleanup even if the function execution exceeds the time limit.
  • Terminating signals are handled with the following 2 errors:
SIGALRM function lasted too long # for timeout or exit(status), where status != 0
SISSEGV end! # for term calls

Disclaimer

  1. This was tested on the IOCLA virtual machine.
  2. If all tests fail, make clean && make is advised in both src/ and tests/ and then make check in tests
  3. Tests should be also ran individually if they dont all work in a bulk (we've encountered this before, but wethink we managed to fix it)

Prerequisites

  • The program requires a POSIX-compliant operating system.
  • Ensure that you have a C compiler installed (e.g., GCC).
