Bear-ISSRE17

Bear is a framework for statistical analysis of application sensitivity to OS unpredictability that can help developers build more resilient software, discover challenging bugs and identify the scenarios that most need validation. Bear analyzes a program with a set of perturbation strategies on a set of commonly used system calls in order to discover the most sensitive system calls for each application, the most impactful strategies, and how they predict abnormal program outcome.

Key Features

  1. A system call perturbation module LKM/
    • statically or dynamically hook system calls for adding perturbation strategies
  2. A statistical module Rcode/
    • analyze different thresholds and workloads
  3. Examples to run the project
    • use examples in Logs/ and see Res/

Environment

  • Virturl machine: Linux Ubuntu 12.04
  • R studio

Configuration and Run

To make and install the perturbation module

cd LKM/ & make
sudo insmod hook.ko TARGET=app_name stratNo=number callname=syscall

update the app_name, number, and syscall parameters based on your demands

To run the statistical module, please update the paths with your own data. Possible places to change the path.
