2019-11-20net: IPv6, accept_ra, slaac, stateless (#51)Harald
Router advertisements are required for the default route to be set up, thus accept_ra should be enabled for dhcpv6-stateful. sysconf: IPV6_FORCE_ACCEPT_RA controls accept_ra sysctl. eni: mode static and mode dhcp 'accept_ra' controls sysctl. Add 'accept-ra: true|false' parameter to config v1 and v2. When True: accept_ra is set to '1'. When False: accept_ra is set to '0'. When not defined in config the value is left to the operating system default. This change also extend the IPv6 support to distinguish between slaac and dhcpv6-stateless. SLAAC is autoconfig without any options from DHCP, while stateless auto-configures the address and the uses DHCP for other options. LP: #1806014 LP: #1808647
2019-11-04azure: support matching dhcp route-metrics for dual-stack ipv4 ipv6Chad Smith
Network v2 configuration for Azure will set both dhcp4 and dhcp6 to False by default. When IPv6 privateIpAddresses are present for an interface in Azure's Instance Metadata Service (IMDS), set dhcp6: True and provide a route-metric value that will match the corresponding dhcp4 route-metric. The route-metric value will increase by 100 for each additional interface present to ensure the primary interface has a route to IMDS. Also fix dhcp route-metric rendering for eni and sysconfig distros. LP: #1850308
2019-10-31net: fix subnet_is_ipv6() for stateless|statefulHarald Jensås
Function return false for ipv6_dhcpv6-stateless|stateful, the eni renderer does not add '6' to 'inet' which is incorrect. The subnet_is_ipv6() function is updated to also return true if startswith('ipv6'). LP: #1848690
2019-10-24Fix usages of yaml, and move yaml_dump to safeyaml.dumps.Scott Moser
Here we replace uses of the pyyaml module directly with functions provided by cloudinit.safeyaml. Also, change/move cloudinit.util.yaml_dumps to cloudinit.safeyaml.dumps LP: #1849640
2019-08-13azure/net: generate_fallback_nic emits network v2 config instead of v1Chad Smith
The function generate_fallback_config is used by Azure by default when not consuming IMDS configuration data. This function is also used by any datasource which does not implement it's own network config. This simple fallback configuration sets up dhcp on the most likely NIC. It will now emit network v2 instead of network v1. This is a step toward moving all components talking in v2 and allows us to avoid costly conversions between v1 and v2 for newer distributions which rely on netplan.
2019-07-18Fix bug rendering MTU on bond or vlan when input was netplan.Scott Moser
If input to network_state.parse_net_config_data was netplan (v2 yaml) then the network state would lose the mtu information on bond or vlan. LP: #1836949
2019-05-29netplan: update netplan key mappings for gratuitous-arpRyan Harper
Previous versions of netplan included a misspelling for the bond parameter around gratuitous-arp. This has been fixed and released and cloud-init needs to accept both values. This branch fixes the key that will be rendered and transforms the previous misspelling when capturing network_state. LP: #1827238
2019-03-12net/sysconfig: Handle default route setup for dhcp configured NICsRobert Schweikert
When the network configuration has a default route configured and another network device that is configured with dhcp, SUSE sysconfig output should not accept the default route provided by the dhcp server. LP: #1812117
2019-03-04net: append type:dhcp[46] only if dhcp[46] is True in v2 netconfigKurt Stieger
When providing netplan configuration to cloud-init, the internal network state would enable DHCP if the 'dhcp' key was present in the source config. In netplan, dhcp[46] is a boolean and the value of the boolean should control whether DHCP is enabled rather than the presence of the key. This issue leaded to inconsistant sysconfig/network-scripts on fedora. 'BOOTPROTO' was always 'dhcp', even if the address config was static. After this change a dhcp subnet is added only if the 'dhcp' setting in source cfg dict is True. LP: #1818032
2018-09-26Add support for Infiniband network interfaces (IPoIB).Mark Goddard
OpenStack ironic references Infiniband interfaces via a 6 byte 'MAC address' formed from bytes 13-15 and 18-20 of interface's hardware address. This address is used as the ethernet_mac_address of Infiniband links in network_data.json in configdrives generated by OpenStack nova. We can use this address to map links in network_data.json to their corresponding interface names. When generating interface configuration files, we need to use the interface's full hardware address as the HWADDR, rather than the 6 byte MAC address provided by network_data.json. This change allows IB interfaces to be referenced in this dual mode - by MAC address and hardware address, depending on the context. Support TYPE=InfiniBand for sysconfig configuration of IB interfaces.
2018-04-18net: Depend on iproute2's ip instead of net-tools ifconfig or routeChad Smith
The net-tools package is deprecated and will eventually be dropped. Use "ip route", "link" or "address" instead of "ifconfig" or "route" calls. Cloud-init can now run in an environment that no longer has net-tools. This affects the network and route printing emitted to cloud-config-output.log as well as the cc_disable_ec2_metadata module. Additional changes:  - separate readResource and resourceLocation into standalone test    functions  - Fix ipv4 address rows to report scopes represented by ip addr show  - Formatted route/address ouput now handles multiple ipv4 and ipv6    addresses on a single interface Co-authored-by: James Hogarth <james.hogarth@gmail.com> Co-authored-by: Robert Schweikert <rjschwei@suse.com>
2018-03-20OpenNebula: Update network to return v2 config rather than ENI.Akihiko Ota
OpenNebulaNetwork.gen_conf() was previously returning ENI format. This is updated to return netplan/v2 config. The changes here also adds support for IPv6 configuration distributed from OpenNebula and fixes some issues about nameserver information.
2018-03-16netplan: render bridge port-priority valuesRyan Harper
Update netplan renderer to write out bridge port-priority values now that netplan supports the feature. LP: #1735821
2018-01-24Azure VM Preprovisioning support.Douglas Jordan
This change will enable azure vms to report provisioning has completed twice, first to tell the fabric it has completed then a second time to enable customer settings. The datasource for the second provisioning is the Instance Metadata Service (IMDS),and the VM will poll indefinitely for the new ovf-env.xml from IMDS. This branch introduces EphemeralDHCPv4 which encapsulates common logic used by both DataSourceEc2 an DataSourceAzure for temporary DHCP interactions without side-effects. LP: #1734991
2017-12-15lint: Fix lints seen by pylint version 1.8.1.Chad Smith
This branch resolves lints seen by pylint revision 1.8.1 and updates our pinned tox pylint dependency used by our tox pylint target.
2017-11-21sysconfig: Correctly render dns and dns search info.Ryan McCabe
Currently when dns and dns search info is provided, it is not rendered when outputting to sysconfig format. This patch causes the DNS and DOMAIN lines to be written out rendering sysconfig. LP: #1705804
2017-10-05net: Handle bridge stp values of 0 and convert to boolean typeChad Smith
Update unit tests to pass a 0 instead of 'off' to validate that network state is properly written.
2017-10-05network: bridge_stp value not always correctRyan Harper
Update network_state to store the bridge_stp value as a boolean. The various renderers then can map the boolean value to the correct output as needed; eni uses 'on/off', sysconfig uses 'yes/no' and netplan will use the boolean directly. Update unittest values for sysconfig and netplan. Both contained the network_state string value which resulted in not correctly enable/disable STP in the target system. Update network_state comment (fd -> forward-delay, add stp as boolean) on bridge commands to match the expected format of a netplan bridge command. LP: #1721157
2017-08-15network: add v2 passthrough and fix parsing v2 config with bonds/bridge paramsRyan Harper
If the network-config sent to cloud-init is in version: 2 format then when rendering netplan, we can pass the content through and avoid consuming network_state elements. This removes the need for trying to map many v2 features onto network state where other renderers won't be able to use anyhow (for example match parameters for multi-interface configuration and wifi configuration support). Additionally ensure we retain bond/bridge v2 configuration in network state so when rendering to eni or sysconfig we don't lose the configuration - Drop the NotImplemented wifi exception, log a warning that it works for netplan only - Adjust unittests to new code path and output - Fix issue with v2 macaddress values getting dropped - Add unittests for consuming/validating v2 configurations LP: #1709180
2017-06-08net: normalize data in network_state objectScott Moser
The network_state object's network and route keys would have different information depending upon how the network_state object was populated. This change cleans that up. Now: * address will always contain an IP address. * prefix will always include an integer value that is the network_prefix for the address. * netmask will be present only if the address is ipv4, and its value will always correlate to the 'prefix'.
2017-05-26net: fix reading and rendering addresses in cidr format.Dimitri John Ledkov
Input (specifically OpenStack) that had: "ip_address" : "104.130.20.155", "netmask" : "255.255.255.0" Was being rendered to netplan as '104.130.20.155/255.255.255.0'. That is now fixed to '104.130.20.155/24' Also fixed is reading of a route that had a network prefix integer in the 'netmask' rather than a netmask. LP: #1689346 LP: #1684349
2017-04-21pylint: fix all logging warningsJoshua Powers
This will change all instances of LOG.warn to LOG.warning as warn is now a deprecated method. It will also make sure any logging uses lazy logging by passing string format arguments as function parameters.
2017-03-24test: add running of pylintJoshua Powers
Now tox will run pylint. The .pylintrc file sets pylint to only produce errors, and will ignore certain classes that are known problematic (six).
2017-03-20cloudinit.net: add network config v2 parsing and renderingRyan Harper
Network configuration version 2 format is implemented in a package called netplan (nplan)[1] which allows consolidated network config for multiple network controllers. - Add a new netplan renderer - Update default policy, placing eni and sysconfig first This requires explicit policy to enable netplan over eni on systems which have both (Yakkety, Zesty, UC16) - Allow any network state (parsed from any format cloud-init supports) to render to v2 if system supports netplan. - Move eni's _subnet_is_ipv6 to common code for use by other renderers - Make sysconfig renderer always emit /etc/syconfig/network configuration - Update cloud-init.service systemd unit to also wait on systemd-networkd-wait-online.service 1. https://lists.ubuntu.com/archives/ubuntu-devel/2016-July/039464.html
2017-03-17support 'loopback' as a device type.Scott Moser
As reported in bug 1671927, sysconfig had an issue with rendering a loopback device. The problem was that some as yet unknown issue was causing the openstack config drive to parse the provided ENI file rather than reading the network_data.json. Parsing an ENI file would add a a 'lo' device of type 'physical', and sysconfig was failing to render that. The change here is: a.) add a 'loopback' type rather than 'physical' for network config. {'name': 'lo', 'type': 'loopback', 'subnets': ['type': 'loopback']} b.) support skipping that type in the eni and sysconfig renderers. c.) make network_state just piggy back on 'physical' renderer for loopback (this was what was happening before). Tests are added for eni and sysconfig renderer.
2016-12-22LICENSE: Allow dual licensing GPL-3 or Apache 2.0Jon Grimm
This has been a recurring ask and we had initially just made the change to the cloud-init 2.0 codebase. As the current thinking is we'll just continue to enhance the current codebase, its desirable to relicense to match what we'd intended as part of the 2.0 plan here. - put a brief description of license in LICENSE file - put full license versions in LICENSE-GPLv3 and LICENSE-Apache2.0 - simplify the per-file header to reference LICENSE - tox: ignore H102 (Apache License Header check) Add license header to files that ship. Reformat headers, make sure everything has vi: at end of file. Non-shipping files do not need the copyright header, but at the moment tests/ have it.
