Development Log
2/17
- Found exactly how to create a test
2/19
- Found best files to begin trying to fuzz
2/24
- Made basic programs using zzuf and afl to begin fuzzing
2/27
- Tried to integrate AFL with BRL-CAD tests
3/2
- Began learning and practicing new fuzzer -- LibFuzzer
- Went through tutorials on LibFuzzer and wrote sort programs to run it on
- Followed this tutorial: https://github.com/google/fuzzing/blob/master/tutorial/libFuzzerTutorial.md
3/4
- Tried to link LibFuzzer target to BRL-CAD library
- Struggled with the compilation of BRL-CAD (required installing libraries not needed before)
- Struggled with compiling target so it had BRL-CAD libraries
3/9
- Experimented with compiling target and consulted Shikhar, a PHd student at UT
- Found the BRL-CAD header file and the exact syntax needed to fully compile my target
- Built the target, ran it in various ways tinkering with how the data was input into bu_sort, checking if the output was correct, adding seeds to the input
- Used this compilation statement
clang++ -g -O1 -fsanitize=fuzzer -Iinclude -Ibuild/include -Ibuild/include/openNURBS/ target.cc -Lbuild/lib -Wl,-rpath -Wl,build/lib -lrt -lbu
3/23
- Learned Jenkins CI and successfully built BRL-CAD
- Started creating a build to test BRL-CAD immediately
3/25
- Fixed testing BRL-CAD in Jenkins
- Began creating infrastructure for a "make fuzz"
3/30
- Looked at other regression tests cmake files to find what exactly is required to compile
- Tried to mimic these to compile fuzzing tests
4/1
- Switched strategies for compiling using cmake, spent most of my time reading documentation to better understand how exactly cmake works and how that can be applied to fuzzing
4/13
- Figured out how to create a fuzz directory in the build
- Began writing run.sh to find libraries and compile the test
- Used the benchmark file to base the run.sh off of but cannot figure out how to find the target
4/17
- Much closer to compiling target -- using add_executable and linking targets with target_link_libraries
- Found how to link libfuzzer with the target in cmake
- Added dependency bu
- Still having trouble figuring out how to add the dependency rt
- Getting error that it is an executable that cannot be shared
