charset="utf-8" From: Alexander Bulekov OSS-Fuzz changed the way it scans for fuzzers in $DEST_DIR. The new code also scans subdirectories for fuzzers. This means that OSS-Fuzz is considering bin/qemu-fuzz-i386 as an independent fuzzer (it is not - it requires a --fuzz-target argument). This has led to coverage-build failures and false crash reports. To work around this, we take advantage of OSS-Fuzz' filename extension check - OSS-Fuzz will not run anything that has an extension that is not ".exe": https://github.com/google/oss-fuzz/blob/master/infra/utils.py#L115 Reported-by: OSS-Fuzz (Issue 26725) Reported-by: OSS-Fuzz (Issue 26679) Signed-off-by: Alexander Bulekov Message-Id: <20201101212245.185819-1-alxndr@bu.edu> Signed-off-by: Paolo Bonzini --- scripts/oss-fuzz/build.sh | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/scripts/oss-fuzz/build.sh b/scripts/oss-fuzz/build.sh index fcae4a0c26..3b1c82b63d 100755 --- a/scripts/oss-fuzz/build.sh +++ b/scripts/oss-fuzz/build.sh @@ -91,7 +91,7 @@ make "-j$(nproc)" qemu-fuzz-i386 V=3D1 # Copy over the datadir cp -r ../pc-bios/ "$DEST_DIR/pc-bios" =20 -cp "./qemu-fuzz-i386" "$DEST_DIR/bin/" +cp "./qemu-fuzz-i386" "$DEST_DIR/bin/qemu-fuzz-i386.base" =20 # Run the fuzzer with no arguments, to print the help-string and get the l= ist # of available fuzz-targets.
