[Bug 1799487] Re: Support for sit (ipv6) tunnels

Wed May 8 00:00:42 UTC 2019

This bug was fixed in the package netplan.io - 0.96-0ubuntu0.18.04.4

---------------
netplan.io (0.96-0ubuntu0.18.04.4) bionic; urgency=medium

  * debian/patches/git_revert_explicit_renderer_def_ebc212a.patch: revert
    commit ebc212a: make renderer values explicit at the end of each parsing
    pass; it breaks "default" renderer behavior when multiple files may set
    a global renderer and expect the last to take effect globally.
    (LP: #1825206)
  * debian/patches/git_reorg_netdef_validation_181b583.patch: correct the
    fallout from the above change: validate netdefs in a single pass at the
    very end of parsing, once we know which is the applicable renderer. This
    makes sure tunnels get validated correctly.

netplan.io (0.96-0ubuntu0.18.04.3) bionic; urgency=medium

  * debian/patches/disable-networkd-tunnels-ipip-gre.patch: disable IPIP and
    GRE tunnel tests; those appear to be broken because neither the kernel nor
    networkd bring up the device automatically as in other releases.

netplan.io (0.96-0ubuntu0.18.04.2) bionic; urgency=medium

  * d/p/0001-Partially-revert-the-change-for-enabling-systemd-net.patch:
    Partially revert changes to networkd jobs ordering: leave systemd-networkd
    enabled in multi-user.target instead of network-online.target, as in some
    minimal setups there might be no job requiring network-online.target,
    whereas the natural target to reach for booting is multi-user.target.
    (LP: #1821867)

netplan.io (0.96-0ubuntu0.18.04.1) bionic; urgency=medium

  * Backport netplan.io 0.96 to 18.04.
  * debian/patches/glib_changes.patch: Patch tests to work again on older GLib.
  * debian/control: adjust Depends for bionic / re-add nplan package.

    - Refactored unit and integration tests, along with various cleanups.
    - Add DHCP overrides to control route usage and default metric for DHCP
      routes. (LP: #1776228)
    - Mitigate against bad matching on devices behind bonds then they share
      the same MAC from a physical interface. (LP: #1804861)
    - Added snapcraft.yaml.

netplan.io (0.90.1) disco; urgency=medium

  * Do not assume /etc/network exists in postinst, as netbase 5.5 no longer
    creates it.
  * netplan/cli/commands/ip.py: fix a flake.

  * New upstream release:
    - build: fixes for building on RPM-based distros

  Support for sit (ipv6) tunnels

Bug description:
  [Impact]
  Ubuntu users who need to configure IP tunnels for their network.

  [Test case]
  1) Sign-up / set up an Hurricane Electric tunnel at www.tunnelbroker.net.
  2) Configure netplan for the new tunnel. e.g.

  network:
    version: 2
    renderer: networkd
    ethernets:
      eth0:
        addresses:
          - 1.1.1.1/24
          - "2001:cafe:face::1/64"  # provided by HE as routed /64
        gateway4: 1.1.1.254
    tunnels:
      he-ipv6:
        mode: sit
        remote: 2.2.2.2
        local: 1.1.1.1
        addresses:
          - "2001:dead:beef::2/64"
        gateway6: "2001:dead:beef::1"

  3) Run 'netplan apply' or reboot to apply the new configuration.

  [Regression potential]
  None; this adds a new type of device not previously available to users.

  Like many I use tunnelbroker.net for IPv6 connectivity on servers that
  lack native IPv6 connectivity through their provider.

  Back in ifupdown, this was done with a nice and short snippet that looked like this:
  ```
  auto he-ipv6
  iface he-ipv6 inet6 v4tunnel
      address 2001:470:1c:1d7::2
      netmask 64
      endpoint 216.66.38.58
      local 192.222.186.156
      mtu 1480
      ttl 64
  ```

  There is however no equivalent in netplan that I could find (on 18.04
  at least), instead I had to do the following to get networkd to setup
  the tunnel.

  1) Define a netdev (/etc/systemd/network/he-ipv6.netdev)
  ```
  [NetDev]
  Name=he-ipv6
  Kind=sit
  MTUBytes=1480

  [Tunnel]
  Local=54.39.107.213
  Remote=216.66.38.58
  TTL=64
  ```

  2) Define a network (/etc/systemd/network/he-ipv6.network)
  ```
  [Match]
  Name=he-ipv6

  [Network]
  Address=2001:470:1c:b62::2/64
  Gateway=2001:470:1c:b62::1
  ```

  3) Setup a dependency between my WAN interface and the tunnel (/etc/systemd/network/10-netplan-eth0.network.d/tunnel.conf)
  ```
  [Network]
  Tunnel=he-ipv6
  ```

  This then all works fine but has the very annoying side-effect of
  splitting my network config into a bunch of different pieces with
  everything in my netplan.yaml except for that tunnel which I have to
  configure directly in networkd and use systemd unit overrides to add
  the needed Tunnel statement to the netplan managed wan interface.
