SparseBoomerang

SparseBoomerang is an extension to SPDS-based Boomerang. This SparseBoomerang repository is now the main fork of CodeShield's Boomerang which is providing further maintainance and development. SparseBoomerang introduces two sparsification strategies to aid the scalability of precise Boomerang pointer analysis. SparseBoomerangCorrectness show how these work and compare them against the default non-sparse Boomerang.

FlowDroid with SparseBoomerang

The FlowDroid fork that works with SparseBoomerang is available at: https://github.com/kadirayk/FlowDroid

Publications

The paper is available: Two Sparsification Strategies for Accelerating Demand-Driven Pointer Analysis (ICST 2023)

Preprint is available: Two Sparsification Strategies for Accelerating Demand-Driven Pointer Analysis (ICST 2023)

Boomerang

This repository contains a Java implementation of Synchronized Pushdown Systems. Additionally, it contains an implementation of Boomerang and IDEal based on a Weighted Pushdown System.

Use as Maven dependency

The projects are released on Maven Central and can be included as a dependency in .pom files (replace x.y.z with the latest version).

  • Boomerang can be included with the following dependency:
<dependency>
  <groupId>de.fraunhofer.iem</groupId>
  <artifactId>boomerangPDS</artifactId>
  <version>x.y.z</version>
</dependency>
  • IDEal can be included with the following dependency:
<dependency>
  <groupId>de.fraunhofer.iem</groupId>
  <artifactId>idealPDS</artifactId>
  <version>x.y.z</version>
</dependency>

Checkout, Build and Install

To build and install SPDS into your local repository, run

mvn clean install -DskipTests

in the root directory of this git repository. If you do not want to skip the test cases, remove the last flag.

Examples

Boomerang code examples can be found here. Code examples for IDEal are given here.

Notes on the Test Cases

The projects Boomerang and IDEal contain JUnit test suites. As for JUnit, the test methods are annotated with @Test and can be run as normal JUnit tests. However, these methods are not executed but only statically analyzed. When one executes the JUnit tests, the test method bodies are supplied as input to Soot and a static analysis is triggered. All this happens in JUnit's @Before test time. The test method itself is never run, may throw NullPointerExceptions or may not even terminate.

If the static analysis succeeded, JUnit will officially label the test method as skipped. However, the test will not be labeled as Error or Failure. Even though the test was skipped, it succeeded. Note, JUnit outputs a message:

org.junit.AssumptionViolatedException: got: <false>, expected: is <true>

This is ok! The test passed!
