regression: UFO removal breaks kvm live migration

Hello, I just received this bug report: https://bugzilla.suse.com/show_bug.cgi?id=1066757 The reporter runs a live migration of a kvm guest from a host with kernel supporting UFO (openSUSE 42.2 or 42.3, based on 4.4) to a host with kernel with UFO support removed (SLE15 or openSUSE 15.0

[PATCH net-next 1/2] ip_gre: add the support for i/o_flags update via netlink

Now ip_gre is using ip_tunnel_changelink to update it's properties, but ip_tunnel_changelink in ip_tunnel doesn't update i/o_flags as a common function. o_flags updates would cause that tunnel->tun_hlen / hlen and dev->mtu / needed_headroom need to be recalculated, and dev->(hw_)features need to

[PATCH net-next 0/2] ip_gre: add support for i/o_flags update

ip_gre is using as many ip_tunnel apis as possible, newlink works fine as gre would do it's own part in .ndo_init. But when changing link, ip_tunnel_changelink doesn't even update i/o_flags, and also the update of these flags would cause some other gre's properties need to be updated or

[PATCH net-next 2/2] ip_gre: add the support for i/o_flags update via ioctl

As patch 'ip_gre: add the support for i/o_flags update via netlink' did for netlink, we also need to do the same job for these update via ioctl. This patch is to update i/o_flags and call ipgre_link_update to recalculate these gre properties after ip_tunnel_ioctl does the common update.

[PATCH net-next 1/2] net: allow per netns sysctl_rmem and sysctl_wmem for protos
