2016-06-14Add support for OVS patch portsJames Slagle2-0/+60
OVS patch ports are used to connect two OVS bridges so traffic can flow between them. This is generally useful for various cases. Specifically it could be used to connect the bridges created by TripleO networking configurations (br-ex, etc) to the bridge created by the multinode networking setup in infra's nodepool (br_pub). This allows the nodes in a multinode deployment to have connectivity across private subnets where such traffic is typically firewalled off in public clouds.

2016-03-07Enable os_net_config to configure IVSxinwu2-0/+61
This change generates /etc/sysconf/network-scripts/ifcfg-* for ivs. It also generates /etc/sysconf/ivs configuration file for ivs. It supports only RedHat at this point. Indigo Virtual Switch (IVS, https://github.com/floodlight/ivs) is a virtual switch for Linux. It is compatible with the KVM hypervisor and leveraging the Open vSwitch kernel module for packet forwarding. There are three major differences between IVS and OVS: 1. Each node can have at most one ivs, name is not required. 2. Bond is not allowed to attach to an ivs. It is the SDN controller's job to dynamically form bonds on ivs. 3. IP address can only be statically assigned. Change-Id: I276d736794d123405de793c2a4eb2c1ee55a0fad
2015-10-12Add Linux Bridge capability to os-net-config ifcfgDan Sneddon1-0/+9
This patch adds support for Linux Bridges to os-net-config. This is done completely with ifcfg files, brctl is not used directly. Hierarchy is preserved, so a Linux Bridge may have a Linux Bond as a member, which in turn may have multiple interfaces as members. This changeset has been updated to include a more specific example for Linux bridge configuration (that doesn't combine bridging and bonding). This change depends on the change to add support for Linux Bonds. Change-Id: I1ddacd514b02af30139a868071d82cde19b1f946
2015-10-05Add support for Linux Bonding to os-net-config ifcfgDan Sneddon1-0/+13
This change adds support for Linux Bonding to the impl_ifcfg in os-net-config. This change adds support for configuring Linux Bonds using the Bonding module rather than Open vSwitch. Most of the options for Linux Bonds are the same as OVS, with the exception of bonding_options instead of ovs_options. Change-Id: If8c6de1554234277843de9fac58536dd5b0a941b
2015-05-11Add flag for DEFROUTE=no in ifcfg files to ignore DHCP gatewayDan Sneddon2-0/+23
When multiple interfaces are configured with DHCP, and more than one interface receives a gateway from the DHCP server(s), the resulting default gateway on the system is unpredictable. This change adds the "defroute" boolean to the configuration syntax for os-net-config. Any interface type may be marked so that the gateway received from the DHCP server will not be eligible as a default gateway for the system. This only works for ifcfg files, /etc/network/interfaces lacks an equivalent option. Change-Id: Id775f3506b2ec60c9a2833efd49fb8319151c00d Closes-Bug: 1449288

2015-02-24Add a persist_mapping option to the mapping fileSteven Hardy1-0/+4
This adds the option to permanently rewrite the configuration so the aliases are used instead of the system name. This is useful where you have a variety of hardware and you want to have consistent device naming accross all platforms - this allows you to essentially rename the interfaces permanently so they match the abstracted nicN names. Note, this needs to be run with --cleanup or the old (now conflicting) configs will still be in place, and it may require a reboot before the changes are fully applied.

2015-02-24Add mapping option to influence nicN mapping orderSteven Hardy2-0/+31
Currently there's a fixed mapping between abstracted interface names (nic1, nic2 etc) and the underlying biosdevname for the device. In many cases, this mapping based on system enumeration is sufficient, but in some cases, particularly when you perform detailed pre-deployment discovery of interfaces, you may wish to alter the mapping independently of the config (e.g if the config is in a heat template, and the discovery data is provided at runtime). So this adds a -m option to os-net-config, which enables a mapping file to be provided, such that specific interfaces may be mapped to their abstract names based on knowledge of the devices or the networks they are connected to. The mapping file has the following format, where em1 and em2 are device names as detected by the OS (e.g biosdevname): interface_mapping: nic1: em2 nic2: em1 Or you can use the device MAC instead: interface_mapping: nic1: 12:34:56:78:9a:bc nic2: 12:34:56:de:f0:12 Change-Id: I93e6d3ed733244834bb3c2126c91db705b4d9167

2015-01-14Add sample and cli test for simple interface configSteven Hardy2-0/+21
Adds a simple example showing how an individual interface can be configured, e.g outside of a bond etc. Change-Id: I05dcb4fabe718686e306bdc719b32f0fb40c1b5e

2014-08-21A vlan on an OVS bridge doesn't require a deviceDan Prince2-11/+18
Updates the object model so that a VLAN on top of a bridge (an OVS int port) doesn't require a physical device to be set in the object model.
2014-08-20Add support for parsing YAMLDan Prince4-1/+43
Adds new YAML examples. Also adds some new CLI test cases which compare --noop stdout (from the CLI) for the json and yaml examples to verify they generate the same things.
