Title:
Setting ipv6.disable=1 prevents both IPv4 and IPv6 socket opening for
VXLAN tunnels
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Xenial:
Fix Released
Bug description:
[Impact]
When booting with ipv6.disable=1, vxlan tunnels will fail to
initialize with the error "vxlan: Cannot bind port 4789, err=-97"
which is EAFNOSUPPORT.
Expected result is that vxlan tunnels work when ipv6 is disabled.
# Tested on :
Description: Ubuntu 16.04.4 LTS
Release: 16.04
Kernel : linux-image-4.4.0-124-generic
[Test Case]
Deploy two identical 14.04 nodes with the following configuration:
Add the following to /etc/default/grub then run 'sudo update-grub'
GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1"
Reboot both nodes
sudo reboot
Set up a tunnel using the following commands on each node modifying
remote_ip to be the ip of the other node. modify veth0 ip to be subnet
using the tunnel 10.10.10.x/24
ovs-vsctl del-port br-int vx1
ovs-vsctl del-port br-int veth1
ip link del veth0
ovs-vsctl add-port br-int vx1 -- set interface vx1 type=vxlan
options:remote_ip=192.168.122.161
# remote_ip should be the ip of the other node
ip link add type veth
ip link set veth0 up
ip link set veth1 up
ovs-vsctl add-port br-int veth1
ip addr add 10.10.10.2/24 dev veth0 # on the second node use 10.10.10.3/24
Expected result is once the tunnel is configured on each side, you
should be able to ping the ip of veth0 on the remote side while ipv6
is disabled.
ping 10.10.10.2 or 10.10.10.3, whichever is the remote side.
[Regression Potential]
Regression Potential = Low.
This has been tested by more than one person (pre-SRU) and the patch
provide the expected behaviour for this particular bug.
