From b22ea4ef4c3438817fcb604255b55b0058ed8c64 Mon Sep 17 00:00:00 2001 From: Guillaume Nault Date: Fri, 26 Apr 2024 17:27:19 +0200 Subject: [PATCH] vxlan: Add missing VNI filter counter update in arp_reduce(). VXLAN stores per-VNI statistics using vxlan_vnifilter_count(). These statistics were not updated when arp_reduce() failed its pskb_may_pull() call. Use vxlan_vnifilter_count() to update the VNI counter when that happens. Fixes: 4095e0e1328a ("drivers: vxlan: vnifilter: per vni stats") Signed-off-by: Guillaume Nault Signed-off-by: David S.
