fuzz: disable leak-detection for oss-fuzz builds

2024-05-29T10:41:56Z

When we are building for OSS-Fuzz, we want to ensure that the fuzzer targets are actually created, regardless of leaks. Leaks will be detected by the subsequent tests of the individual fuzz-targets.

system: Rename softmmu/ directory as system/

The softmmu/ directory contains files specific to system emulation. Rename it as system/. Update meson rules, the MAINTAINERS file and all the documentation and comments. Signed-off-by: Philippe Mathieu-Daudé Message-ID: <20231004090629.37473-14-philmd@linaro.org> Signed-off-by: Paolo Bonzini

scripts/oss-fuzz: add a suppression for keymap

gitlab: add lsan suppression file to workaround tcmalloc issues

2023-02-02T10:44:23Z

The up-coming upgrade to Fedora 37 will bring in libtcmalloc as a dependency of libglusterfs which confuses our fuzz run. Rather than disable the build lets use LSAN's suppression mechanism to prevent the job from failing. Signed-off-by: Alex Bennée Cc: Daniel P.

oss-fuzz: ensure base_copy is a generic-fuzzer

2022-07-22T17:01:44Z

Depending on how the target list is sorted in by qemu, the first target (used as the base copy of the fuzzer, to which all others are linked) might not be a generic-fuzzer. Since we are trying to only use generic-fuzz, on oss-fuzz, fix that, to ensure the base copy is a generic-fuzzer.

oss-fuzz: remove binaries from qemu-bundle tree

2022-07-22T17:01:44Z

oss-fuzz is finding possible fuzzing targets even under qemu-bundle/.../bin, but they cannot be used because the required shared libraries are missing. Since the fuzzing targets are already placed manually in $OUT, the bindir and libexecdir subtrees are not needed; remove them. Cc: Alexander Bulekov Signed-off-by: Paolo Bonzini

datadir: Use bundle mechanism

2022-07-13T14:58:57Z

softmmu/datadir.c had its own implementation to find files in the build tree, but now bundle mechanism provides the unified implementation which works for datadir and the other files.

fuzz: only use generic-fuzz targets on oss-fuzz

2022-07-08T09:03:36Z

The non-generic-fuzz targets often time-out, or run out of memory. Additionally, they create unreproducible bug-reports. It is possible that this is resulting in failing coverage-reports on OSS-Fuzz. In the future, these test-cases should be fixed, or removed.

Since commit a2ce7dbd917 ("meson: convert tests/qtest to meson"), libqtest.h is under libqos/ directory, while libqtest.c is still in qtest/.
