scripts/oss-fuzz: rename bin/qemu-fuzz-i386
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 <alxndr@bu.edu> Message-Id: <20201101212245.185819-1-alxndr@bu.edu> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
