| − | *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

| − | *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
| |
| − |
| |
| − | == 4/27 ==
| |
| − | *Changed compiler to Clang for building BRL-CAD
| |
| − | *Successfully compiled fuzz test
| |
| − | *Able to run fuzz test with "make fuzz"
| |
| − |
| |
| − | == 4/28 ==
| |
| − | *Compiled Sean's random command generator using "make fuzz"
| |
| − |
| |
| − | == 4/29 ==
| |
| − | *Created a patch for local SVN changes
| |
| − |
| |
| − | == 4/30 ==
| |
| − | *Compiled new make fuzz target which runs random commands -- already finds bugs
| |
| − | *Need to find how to record code coverage and improve it
