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
