Build Status

KernelHaven offers a generic infrastructure for performing different analyses on product lines. This repository contains the main infrastructure, plugins are located in separate repositories.


Core Infrastructure

These archives contain the core infrastructure only. Additional plugins are needed for a useful execution.

Bundled Releases

These archives contain the infrastructure as well as all public plugins. These bundles contain more than needed to run most experiments.


The following table lists commonly used plugins for KernelHaven. They mostly focus on analysing the Linux Kernel.

Plugin Type License Download Status
KconfigReaderExtractor VariabilityModel-Extractor: Kconfig GPLv3 Build Status of KconfigReaderExtractor
UndertakerExtractor CodeModel-Extractor: *.c, *.h, *.S GPLv3 Build Status of UndertakerExtractor
TypeChefExtractor CodeModel-Extractor: *.c, *.h Apache License 2.0 Build Status of TypeChefExtractor
srcMLExtractor CodeModel-Extractor: *.c GPLv3 Build Status of srcMLExtractor
KbuildMinerExtractor BuildModel-Extractor: Kbuild*, Makefile* GPLv3 Build Status of KbuildMinerExtractor
CnfUtils Utilities: SAT-Solver, CNF-Converter, Formula simplifiers, ... Apache License 2.0 Build Status of CnfUtils

Plugin Dependencies


Although KernelHaven can be configured to use different paths, the usual setup looks like this:

├── cache/
│   └── ...
├── log/
│   └── ...
├── output/
│   └── ...
├── plugins/
│   ├── cnfutils.jar
│   ├── kbuildminerextractor.jar
│   ├── kconfigreaderextractor.jar
│   ├── undeadanalyzer.jar
│   └── undertakerextractor.jar
├── res/
│   └── ...
├── kernel_haven.jar

A configuration to execute a dead code analysis on Linux with this setup looks like this:

# Linux Source Tree
source_tree = /path/to/linux-4.4
arch = x86

# Analysis
analysis.class = net.ssehub.kernel_haven.undead_analyzer.DeadCodeAnalysis

# Code Extractor = true
code.provider.cache.write = true
code.extractor.class = net.ssehub.kernel_haven.undertaker.UndertakerExtractor
code.extractor.threads = 4

# Build Extractor = true
build.provider.cache.write = true
build.extractor.class = net.ssehub.kernel_haven.kbuildminer.KbuildMinerExtractor

# Variability Extractor = true
variability.provider.cache.write = true
variability.extractor.class = net.ssehub.kernel_haven.kconfigreader.KconfigReaderExtractor

# Logging
log.console = true
log.file = true

# Directories
archive.dir = .
cache_dir = cache/
log.dir = log/
output_dir = output/
plugins_dir = plugins/
resource_dir = res/
