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
4/17
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
