deprecations:
|
|
- The ``iptables`` firewall driver will no longer enable bridge firewalling
|
|
in next versions of Neutron. If your distribution overrides the default
|
|
value for any of relevant sysctl settings
|
|
(``net.bridge.bridge-nf-call-arptables``,
|
|
``net.bridge.bridge-nf-call-ip6tables``, and
|
|
``net.bridge.bridge-nf-call-iptables``) then make sure you set them back
|
|
to upstream kernel default (``1``) using /etc/sysctl.conf or
|
|
/etc/sysctl.d/* configuration files.
|
|
upgrades:
|
|
- On newer Linux kernels (3.18+) you will need to load the ``br_netfilter``
|
|
kernel module before starting an Open vSwitch or Linuxbridge agent using
|
|
``iptables`` firewall driver. Otherwise the agent will fail to start.
