From 0d573787ea1610ba57a359cf437841f62b186e77 Mon Sep 17 00:00:00 2001 From: Yu Watanabe Date: Wed, 12 Jun 2024 00:48:56 +0900 Subject: [PATCH] sd-dhcp-server: clear buffer before receive I do not think this is necessary, but all other places in libsystemd-network we clear buffer before receive. Without this, Coverity warns about use-of-uninitialized-values. Let's silence Coverity. Closes CID#1469721.
