Cryptolib

This directory contains the individual frameworks that are tested with DATA. To add a new framework to test, copy the template directory and adapt the files accordingly.

Preloading

DATA supports preloading shared libraries. This is helpful to override system libraries which are usually stripped of all debug symbols.

glibc

If you want to analyze leakage in glibc, you can build your own glibc with debug symbols enabled. This is done via

cd common/preload/glibc
./build.sh

Note: This might take 2-3 GB of disk space.

Note: If compilation is finished, you can abort the glibc regression tests and re-run ./build.sh which will link the shared library to the preload dir.

Custom libraries

If you want to link other custom libraries, e.g. foo, create a separate folder common/preload/foo where all source and binary files are located. Then, build it and link the shared library to the preload folder, e.g. common/preload/foo.so.

To verify that DATA indeed used the library, check the file env.txt in the results directory. It will list all custom libraries in the LD_PRELOAD environment variable.
