2016-04-05Add MASTER=bond SLAVE=yes to linux bond interfacesDan Prince2-8/+13
When configuring a linux bond with interfaces we have a bug (due to a missing unit test) where the interfaces weren't being configured with MASTER=<bond_name> SLAVE=yes. This patch adds a unit test to check for the required configuration and cleans up the logic in impl_ifcfg.py to handle it correctly by simply checking for the linux_bond_name property which is already set for us via objects.py. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1323717 Change-Id: Ic632c52265dcbbe6c0ace782e633a2030ad25e6f Closes-bug: 1566428
2016-04-05Use interface operstate to determine nic statusChristopher Brown1-4/+4
Fixes lp bug 1555669 Currently _is_active_nic performs multiple checks to see if a link is live. However some hardware such as Ethernet over USB devices fulfil this criteria. This causes tripleo deployments to fail if automatic interface naming is used. We can therefore use operstate to determine if the link is actually up. https://www.kernel.org/doc/Documentation/networking/operstates.txt This patch implements this. Implements: better link state detection Closes-Bug: #1555669 Change-Id: I0bdd0c987f4f177935df4f7cdcc70f4d99c988a5 Signed-off-by: Christopher Brown <snecklifter@gmail.com>
2016-03-25Merge "Fix order-of-operations bug in os-net-config restart_interfaces"Jenkins2-12/+57
2016-03-22Fix order-of-operations bug in os-net-config restart_interfacesDan Sneddon2-12/+57
The current order of operations of bringing up interfaces starts with the bridges, and restarts the members of the bridges. This works well when an OVS bond is part of an OVS bridge, but does not work well when Linux bonding is used with no bridges (such as in the case of the Nuage plugin, which creates the bridges outside of the ifcfg files). This change will ensure that Linux bonds are brought up first, then any bridges are brought up, interfaces are brought up next, and the VLAN interfacs are brought up last. This corrects a race condition where any VLAN which was brought up before the bond would not be active, and the VLAN would have to be brought up by hand. This change also fixes a logging issue where os-net-config would report that no changes were necessary when changes were made. Now, the logging messages indicating that "No changes were necessary" show up when no changes are required, instead of when changes are actually made.

2016-03-11Add ability to set IPv6 routes in os-net-config templatesDan Sneddon2-16/+96
This change adds the ability to write IPv6 routes to the system NIC configuration. In the ifcfg provider, IPv6 routes must be written to network-scripts/route6-<interface> rather than route-interface. This patch checks the next hop, and if it is an IPv6 address (assumed because of the presence of ":"), then the route will be written to route6-<interface>. This patch includes tests to confirm proper operation. Change-Id: I3563800c774a6082a896c7508f5a92e25418fe63
2016-03-11Fix hierarchy for Linux Bonds and Linux BridgesDan Sneddon3-1/+21
This change cleans up some of the Linux Bond and Linux Bridge logic that processes member interfaces and VLANs. One bug is fixed, where a VLAN might be assigned as a slave interface on a bond. Changes were made so that if VLANs are placed under a Linux Bond, the PHYSDEV is set to the bond, so the device: does not need to be specified in the config. This change ensures that if a bridge has a bond and VLANs as members, that the VLAN will be a member of the bridge and not the bond. Change-Id: Id329737f0032e781b111741086ded83f378297a7
2016-03-07Enable os_net_config to configure IVSxinwu7-0/+357
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

2016-02-15Allow setting MTU to 1500Ian Pilcher5-11/+23
There are times when it is desirable to set the MTU of an "interface" to 1500 -- when the external network and the storage network are different VLANs on the same physical interface, for example. Change-Id: Ic5ea6ad05118fd57c26c898a460c19969de4109d Closes-Bug: #1539821
2016-02-12launchpad bug 1537330, fix _is_active_nicxinwu1-5/+3
The detailed bug description is at https://bugs.launchpad.net/os-net-config/+bug/1537330 Since kilo, os-net-config starts to support linux bond. However, the addr_assign_type value of an active member interface of a linux bond is 3, but not 0. The consequence of this problem is that the linux bond member links are never considered as active, this further messes up the nicX to interface name mapping. This change checks if device directory exists, instead of checking the addr_assign_type value. This directory exists only when the interface is an actual physical interface.

2015-10-12Fix kwarg assignment in objects.pyDan Sneddon1-16/+35
This change modifies the kwargs in the object instantiation to use immutable default assignments. This is for object safety, since a mutable object will not point to a new memory address on modification. In Python, lists and dicts should not be used as default assignments for kwargs.

2015-10-12Add Linux Bridge capability to os-net-config ifcfgDan Sneddon6-2/+241
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

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

Currently only the first IPv4/v6 address is assigned to a NIC even if multiple addresses are specified in config file. With this change, eni implementation can configure multiple IPv4/v6 addresses for a NIC. Also this fixes IPv6 netmask format, which currently causes an error on ifup.

2015-08-17os-net-config: ensure ifup is called just onceDan Prince2-1/+10
This patch fixes an issue in the ifcfg provider implementation that caused interfaces to be started twice. This can cause failures if the interface uses DHCP and dhclient was already running. The child_members function was incorrectly adding the interface name to the child members set on key error. This patch removes that logic and simply ignores key errors.

This patch adds a new --detailed-exit-codes option which can be used to optionally enable the os-net-config CLI to return exit code 2 if there have been modifications. Detailed exit codes are useful if you need to trigger subsequent external actions based whether os-net-config made changes or not. Change-Id: I8f22fa15335d1276f4e444a6454a24ff486e1495

2015-07-01Add support for dhclient_argsDan Prince4-15/+50
This patch adds an optional flag that can be used to pass in args for dhclient when using DHCP. This use case for this is to be able to control which DHCP options dhclient listens for and we can thus disable specific options (like routing) for some network configurations.

2015-06-09Automate selection of active bond slaveDan Sneddon2-1/+18
This change selects an interface to be the active slave in a bond with active/passive characteristics. If one of the interfaces is marked as primary, it will be the active slave. If none of the interfaces are marked, the interface with the lowest alphanumeric value will be chosen. For instance em2 comes before em3.

2015-06-09Set primary interface on OVS bondsDan Sneddon3-1/+29
This change sets one of the member interfaces of a bond as the primary interface, which results in that interface being the active slave. This change adds a step to the apply method in impl_ifcfg which runs 'ovs-appctl bond/set-active-slave <bond> <iface>' after bringing up the bond interfaces. This step ensures that the bonds work correctly without LACP switch support. If a member interface on the bond is set as primary, that interface will be used.

2015-06-03Don't set OVSDHCPINTERFACES if bridge is staticDan Prince2-1/+25
Updates the ifcfg provider so that we don't set the OVSDHCPINTERFACES config setting if the interface is private. This doesn't seem to cause any functional issues but it is not required and can be confusing. Change-Id: I9d51905df87969ae1b221680e8f0b5befc7b6bfe

When using the ifcfg provider vlans on bridges (or bonds) fail to startup correctly. This is because VLANs on an OVS bridge are configured as internal ports and these should not have the VLAN=yes or PHYSDEV ifcfg settings specified.
