Subject: [PATCH v3 28/28] checkpatch: Do not allow deprecated g_memdup()
Date: Fri, 3 Sep 2021 19:45:10 +0200 [thread overview]
Message-ID: <20210903174510.751630-29-philmd@redhat.com> (raw)
In-Reply-To: <20210903174510.751630-1-philmd@redhat.com>
g_memdup() is insecure and as been deprecated in GLib 2.68.
QEMU provides the safely equivalent g_memdup2() wrapper.
Do not allow more g_memdup() calls in the repository, provide
a hint to use g_memdup2().
