closes #58 In linux its possible to assign a vlan-aware bridge an ip address For some use cases is it useful to restrict users from configuring ips on bridges VA. This patch will let admins and distributions decide if it is necessary to warn the user in such case. The patch introduces a new 'address' policy: vlan_aware_bridge_address_support: yes|no|on|off|0|1 (default to yes) [16:46:09] root:~ # cat /var/lib/ifupdown2/policy.d/address.json { "address": { "module_globals": { "enable_l3_iface_forwarding_checks": "yes" }, "defaults": { "mtu": "1500", "ip-forward": "on", "ip6-forward": "on" } } } [16:46:16] root:~ # ifquery -a auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp auto bridge iface bridge bridge-ports swp1 bridge-vlan-aware yes address 10.10.10.10/32 [16:46:20] root:~ # ifup -a --syntax-check [16:46:22] root:~ # echo $? 0 [16:46:33] root:~ # nano /var/lib/ifupdown2/policy.d/address.json [16:46:47] root:~ # cat /var/lib/ifupdown2/policy.d/address.json { "address": { "module_globals": { "enable_l3_iface_forwarding_checks": "yes", "vlan_aware_bridge_address_support": "no" }, "defaults": { "mtu": "1500", "ip-forward": "on", "ip6-forward": "on" } } } [16:46:48] root:~ # ifup -a --syntax-check warning: bridge: ignoring ip address.

Installation
============
As of today (early june 2018), the preferred method to install ifupdown2, is by
building the source code (as it will always install the most recent stable
release). See `Installing latest stable release from sources`_ chapter.
Installing latest stable release from sources
---------------------------------------------
The sources for ifupdown2 can be downloaded from the `Github repo`_.
You can either clone the public repository:
.. code-block:: console
$ git clone git://github.com/CumulusNetworks/ifupdown2
Or download the `tarball`_:
.. code-block:: console
$ curl -OL https://github.com/CumulusNetworks/ifupdown2/tarball/master
Once you have a copy of the source, you should build a deb-package and install it
.. code-block:: console
$ cd ifupdown2 && make deb
The generated deb should be in the root directory (``../ifupdown2_2.0.0_all.deb``)
.. code-block:: console
$ dpkg -i ../ifupdown2_2.0.0_all.deb
We don't recommend using ``setup.py install`` directly, as it's still missing systemd/init.d scripts.
This capability should be added in the near future.
You might need to manually download dependencies. Mandatory dependencies:
.. code-block:: console
$ apt-get install dh-systemd python-all python-docutils rst2man iproute2 python-ipaddr python-argcomplete
Suggested dependencies:
.. code-block:: console
$ apt-get install ethtool bridge-utils python-gvgen python-mako
.. _Github repo: https://github.com/CumulusNetworks/ifupdown2
.. _tarball: https://github.com/CumulusNetworks/ifupdown2/tarball/master
