2021-12-25oss-fuzz: use fuzzer_statics for default staticsJan-Marek Glogowski
Change-Id: I3616507127e0661635d87ba2b949ddaa13bc898d Reviewed-on: https://gerrit.libreoffice.org/c/core/+/127454 Tested-by: Jenkins Reviewed-by: Jan-Marek Glogowski <glogow@fbihome.de>
2021-02-28Upgrade fuzzers to LIB_FUZZING_ENGINEAndrzej Hunt
And check that LIB_FUZZING_ENGINE is set during configure. Because: 1. It's easier to build locally this way (you don't need to build or hack a libFuzzingEngine.a - instead you can just specify LIB_FUZZING_ENGINE=-fsanitize=fuzzer to produce a valid build). 2. Using -lFuzzingEngine is deprecated [1] for various reasons [2]. The old behaviour can be emulated if desired by setting LIB_FUZZING_ENGINE=-lFuzzingEngine . This patch was tested as follows: - Building LO within oss-fuzz via: python infra/helper.py build_fuzzers --sanitizer address libreoffice </path/to/patched-libreoffice-core> python infra/helper.py check_build libreoffice - Building LO fuzzers standalone via: export CC="clang-11" export CXX="clang++-11 -stdlib=libc++" export CFLAGS="-fsanitize=address -fsanitize-address-use-after-scope -fsanitize=fuzzer-no-link -DFUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION" export CXXFLAGS="$CFLAGS -stdlib=libc++" export LDFLAGS="$CFLAGS -Wl,--compress-debug-sections,zlib -lpthread" export LIB_FUZZING_ENGINE=-fsanitize=fuzzer ./autogen.sh --with-distro=LibreOfficeOssFuzz --with-system-libxml make fuzzers (--with-system-libxml only appears to be needed because of issues specific to my build environment/Suse 15.2. I'm invoking clang-11 simply because that's the most modern clang I have installed, plain clang should also work on most sufficiently modern systems).

the core lib has grown sufficiently large that the fuzzing tooling complains of too many instrumented conditions so split things up to hopefully fit again Change-Id: I58899d143925f958aec95b5f213c2dc75a6686ec Reviewed-on: https://gerrit.libreoffice.org/38647 Tested-by: Jenkins <ci@libreoffice.org> Reviewed-by: Caolán McNamara <caolanm@redhat.com> Tested-by: Caolán McNamara <caolanm@redhat.com>
