From 8c0b12ac86d9075b76a3906d0c25ba9bc73bbb2c Mon Sep 17 00:00:00 2001 From: "Ondrej Zajicek (work)" Date: Mon, 10 Dec 2018 02:05:21 +0100 Subject: [PATCH] OSPF: Fix reconfiguration of vlinks Fix crash during reconfiguration of OSPF config with vlinks. When vlink is reconfigured, a generic iface-reconfiguration code is used, which in one place supposes that it is running on a regular iface. Thanks to Cybertinus for a bugreport. --- proto/ospf/iface.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/proto/ospf/iface.c b/proto/ospf/iface.c index 6e3a48b3a..feff0f436 100644 --- a/proto/ospf/iface.c +++ b/proto/ospf/iface.c @@ -524,6 +524,10 @@ add_nbma_node(struct ospf_iface *ifa, struct nbma_node *src, int found) static int ospf_iface_stubby(struct ospf_iface_patt *ip, struct ifa *addr) { + /* vlink cannot be stub */ + if (ip->type == OSPF_IT_VLINK) + return 0; + /* a host address */ if (addr->flags & IA_HOST) return 1; -- 2.47.2
