From 3b6fd8227cbb03b5b211d2cb53534ad405673668 Mon Sep 17 00:00:00 2001 From: Matteo Croce Date: Wed, 2 Aug 2017 13:57:17 +0200 Subject: [PATCH] ip neigh: allow flush FAILED neighbour entry Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1469945 Tested: locally using proper reproducer Upstream Status: merged 37a5f7c5 commit 37a5f7c571623059ae671992f72feaa444a6ffc8 Author: Hangbin Liu Date: Fri Jun 16 11:31:52 2017 +0800 ip neigh: allow flush FAILED neighbour entry After upstream commit 5071034e4af7 ('neigh: Really delete an arp/neigh entry on "ip neigh delete" or "arp -d"'), we could delete a single FAILED neighbour entry now. But `ip neigh flush` still skip the FAILED entry. Move the filter after first round flush so we can flush FAILED entry on fixed kernel and also do not keep retrying on old kernel.
