From 5c26159c97b324dc5174a5713eafb8c855cf8106 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 26 Oct 2022 14:32:16 +0200 Subject: ipvs: use explicitly signed chars The `char` type with no explicit sign is sometimes signed and sometimes unsigned. This code will break on platforms such as arm, where char is unsigned. So mark it here as explicitly signed, so that the todrop_counter decrement and subsequent comparison is correct.
