This doesn't guarantee that the builds on oss-fuzz will also succeed, since oss-fuzz provides its own compiler and fuzzer vars, but it can catch changes that are not compatible with the the ./scripts/oss-fuzz/build.sh script. The strange way of finding fuzzer binaries stems from the method used by oss-fuzz: https://github.com/google/oss-fuzz/blob/master/infra/base-images/base-runner/targets_list Signed-off-by: Alexander Bulekov [thuth: Tweak the "script" to make it work, exclude slirp test, etc.] Signed-off-by: Thomas Huth --- Note: Needs Alexander's "fuzz: Fix leak when assembling datadir path string" patch applied first, otherwise it fails due to the leak. .gitlab-ci.yml | 22 ++++++++++------------ 1 file changed, 10 insertions(+), 12 deletions(-) diff --git a/.gitlab-ci.yml b/.gitlab-ci.yml index 41597c3603..362e5ee755 100644 --- a/.gitlab-ci.yml +++ b/.gitlab-ci.yml @@ -164,22 +164,20 @@ build-clang: ppc-softmmu s390x-softmmu arm-linux-user MAKE_CHECK_ARGS: check -build-fuzzer: +build-oss-fuzz: <<: *native_build_job_definition variables: IMAGE: fedora script: - - mkdir build - - cd build - - ../configure --cc=clang --cxx=clang++ --enable-fuzzing - --enable-sanitizers --target-list=x86_64-softmmu - - make -j"$JOBS" all check-build x86_64-softmmu/fuzz - - make check - - for fuzzer in i440fx-qos-fork-fuzz i440fx-qos-noreset-fuzz - i440fx-qtest-reboot-fuzz virtio-scsi-flags-fuzz virtio-scsi-fuzz ; do - echo Testing ${fuzzer} ... ; - x86_64-softmmu/qemu-fuzz-x86_64 --fuzz-target=${fuzzer} -runs=1000 - || exit 1 ; + - mkdir build-oss-fuzz + - CC="clang" CXX="clang++" CFLAGS="-fsanitize=address" + ./scripts/oss-fuzz/build.sh + - for fuzzer in $(find ./build-oss-fuzz/DEST_DIR/ -executable -type f + | grep -v slirp); do + grep "LLVMFuzzerTestOneInput" ${fuzzer} > /dev/null 2>&1 || continue ; + echo Testing ${fuzzer} ... ; + ASAN_OPTIONS="fast_unwind_on_malloc=0" + "${fuzzer}" -runs=1000 -seed=1 || exit 1 ; done build-tci:
