Subject: [PULL 04/20] scripts/oss-fuzz: rename bin/qemu-fuzz-i386
Date: Wed, 4 Nov 2020 10:01:37 -0500 [thread overview]
Message-ID: <20201104150153.541326-5-pbonzini@redhat.com> (raw)
In-Reply-To: <20201104150153.541326-1-pbonzini@redhat.com>
From: Alexander Bulekov <alxndr@bu.edu>
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":
