Subject: [PATCH 17/17] net/virtio: replace strncpy with strlcpy
Date: Tue, 23 Jun 2026 17:51:47 +0100 [thread overview]
Message-ID: <20260623165150.765443-18-bruce.richardson@intel.com> (raw)
In-Reply-To: <20260623165150.765443-1-bruce.richardson@intel.com>
Replace strncpy() with safer strlcpy() which always null-terminates.
