From 4967082b469320eeba54ffbca632af1962858fb7 Mon Sep 17 00:00:00 2001 From: Nicolas Dichtel Date: Mon, 26 Jan 2015 14:10:53 +0100 Subject: vxlan: advertise link netns in fdb messages Previous commit is based on a wrong assumption, fdb messages are always sent into the netns where the interface stands (see vxlan_fdb_notify()). These fdb messages doesn't embed the rtnl attribute IFLA_LINK_NETNSID, thus we need to add it (useful to interpret NDA_IFINDEX or NDA_DST for example). Note also that vxlan_nlmsg_size() was not updated. Fixes: 193523bf9373 ("vxlan: advertise netns of vxlan dev in fdb msg") Signed-off-by: Nicolas Dichtel Signed-off-by: David S.
