* The regression driver serves both as a regression test, and as a binary for afl-fuzz. * Next, we want to check in a seed corpus for each target. Then we can run the regression test binary on them on Travis or Circle CI.
Fuzzing
Each fuzzing target can be built with multiple engines.
LibFuzzer
You can install libFuzzer with make libFuzzer. Then you can make each target
with make target LDFLAGS=-L. CC=clang CXX=clang++.
AFL
The regression driver also serves as a binary for afl-fuzz. You can make each
target with one of these commands:
make target-regression CC=afl-clang CXX=afl-clang++
AFL_MSAN=1 make target-regression-msan CC=afl-clang CXX=afl-clang++
AFL_ASAN=1 make target-regression-uasan CC=afl-clang CXX=afl-clang++
Then run as ./target @@.
Regression Testing
Each fuzz target has a corpus checked into the repo under fuzz/corpora/.
You can run regression tests on the corpora to ensure that inputs which
previously exposed bugs still pass. You can make these targets to run the
regression tests with different sanitizers.
make regression-test
make regression-test-msan
make regression-test-uasan
