From e0aaa332e6a97dae57ad59cdb19e21f83c3d081c Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Mon, 15 Jul 2019 12:00:21 +0200 Subject: [PATCH] xfrm interface: ifname may be wrong in logs The ifname is copied when the interface is created, but is never updated later. In fact, this property is used only in one error message, where the netdevice pointer is available, thus let's use it.
