In linux its possible to assign an ip address to a vlan-aware bridge 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 configuration variable in: /etc/network/ifudpown2/ifupdown2.conf vlan_aware_bridge_address_support: yes|no|on|off|0|1 (default to yes) [8:30:41] root:~ # cat /etc/network/ifupdown2/ifupdown2.conf | grep "vlan_aware_bridge_address_support" [8:30:43] root:~ # ifquery bridge auto bridge iface bridge bridge-ports swp1 bridge-vlan-aware yes address 10.10.10.10 [8:30:46] root:~ # ifup bridge --syntax-check [8:30:52] root:~ # echo $? 0 [8:30:54] root:~ # echo "vlan_aware_bridge_address_support=no" >> /etc/network/ifupdown2/ifupdown2.conf [8:31:11] root:~ # ifup bridge --syntax-check warning: bridge: ignoring ip address.

========= ifupdown2 ========= Linux Interface Network Manager * Free software: GNU General Public License v2 ============ 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 ============ Contributing ============ Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given. You can contribute in many ways: Types of Contributions ---------------------- Report Bugs ~~~~~~~~~~~ Report bugs at https://github.com/CumulusNetworks/ifupdown2/issues. If you are reporting a bug, please include: * Your operating system name and version (``uname -a``). * Any details about your setup that might be helpful in troubleshooting. * Content of configuration files such as ``/etc/network/interfaces`` * Detailed steps to reproduce the bug. * Debug output of the ifupdown2 command (see ``--debug`` option) Write Documentation ~~~~~~~~~~~~~~~~~~~ ifupdown2 could always use more documentation, whether as part of the official ifupdown2 docs, in docstrings, or even on the web in blog posts, articles, and such.
