limtrac's Issues

Initial version of `limtrac` project

Project LIMTRAC - це міні-проєкт зі створення програми для обмеженого виконання процесів у операційних системах на базі GNU/Linux, який буде використовуватися Overtest Verification Agent (overtest-agent) (у вигляді платформо-залежного компоненту). Виконання цього завдання пов'язане з overtest/overtest#2.

  • Побудова скелету (початкової версії) програми
  • Запуск заданої користувачем програми від імені іншого користувача
  • Обмежене використання системних викликів дочірнім процесом
  • Обмеження доступних дочірньому процесу системних ресурсів
