[Bug 1639754] Re: Ethernet devices have higher metric than wlan or wwan ones

 

This bug was fixed in the package nplan - 0.23~16.10.1

---------------
nplan (0.23~16.10.1) yakkety; urgency=medium

  * Backport netplan 0.23 to 16.10. (LP: #1688632)

nplan (0.23) artful; urgency=medium

  * Do not unbind brcmfmac, interface will be gone. (LP: #1696162)

nplan (0.22) artful; urgency=medium

  * Add support for setting a custom MAC address on all device types.
    (LP: #1690388)
  * Improved MAC/vlan integration tests; thanks for Dimitri John Ledkov for the
    changes.

nplan (0.21) artful; urgency=medium

  [ Ryan Harper ]
  * Add support for setting MTU on a device. (LP: #1668693)

  [ Mathieu Trudel-Lapierre ]
  * Don't rebind Atheros AR9271; it would confuse the driver. (LP: #1672740)
  * debian/control: Add Conflicts: against netplan; the network 'plan' daemon.
    Both ship the same /usr/sbin/netplan. (LP: #1665842)

nplan (0.20) zesty; urgency=medium

  * tests/integration.py: increase timeout for integration tests (networkd and
    NetworkManager "wait-online" checks) to account for longer bring-up times
    when dealing with stacked virtual devices.

nplan (0.19) zesty; urgency=medium

  * Add support for unordered definition of network devices: you can now
    specify a virtual devices before their member devices. (LP: #1670495)
  * Allow setting up the STP state for a bridge. (LP: #1665088)
  * Document bond/bridge parameters support. (LP: #1664702)

nplan (0.18) zesty; urgency=medium

  * debian/tests/integration.py: in some cases 'iw reg get' may qualify the
    reg domain results with 'global'; we must not let that trip up tests when
    they are run on Ubuntu infrastructure vs. local tests.

nplan (0.17) zesty; urgency=medium

  * New release:
    - Add support for configuring bonds.
    - Add support for configuring bridges.

nplan (0.16) zesty; urgency=medium

  [ Martin Pitt ]
  * doc/example-config: Adjust "routes:" example.
    It does not make sense to make "routes:" a global thing, they should be
    tied to an interface so that the route is only set when the corresponding
    interface exists and is up, and the config is not split in two parts.
  * doc/netplan.md: Point out that NM does not support globbing (LP: #1631018)

  [ Mathieu Trudel-Lapierre ]
  * Fix coverage for src/netplan to be 100%, and fail if coverage falls below
    that mark again.
  * Add support for specifying routes.

nplan (0.15) zesty; urgency=medium

  * tests/generate.py: Fix PEP-8 error (newly detected by -proposed
    pycodestyle).

nplan (0.14) zesty; urgency=medium

  * tests/generate.py: Introduce macros for commonly expected networkd output
  * networkd: Use NetworkManager compatible DHCP route metrics (LP: #1639754)
  * doc/netplan.md: Fix wrong wifi reference in "br0" example
  * doc/netplan.md: Clarify introduction
  * tests/integration.py: Fix race condition with waiting for networkd

nplan (0.13) zesty; urgency=medium

  [ Jonathan Cave ]
  * Blacklist mwifiex_pcie from rebinds (work around LP: #1630285)

  [ Martin Pitt ]
  * Add support for nameservers (LP: #1626617)

Title:
  Ethernet devices have higher metric than wlan or wwan ones

Status in snappy-hwe-snaps:
  Invalid
Status in nplan package in Ubuntu:
  Fix Released
Status in nplan source package in Xenial:
  Fix Released
Status in nplan source package in Yakkety:
  Fix Released

Bug description:
  [Impact]
  In Ubuntu Core, in all supported devices ethernet devices have higher metric than wlan or wwan devices, so packets get routed to the latter always. The metric is 1024, while for instance network-manager assigns these numbers:

  ethernet -> 100
  wlan -> 600
  wwan -> 700

  This happens because ethernet devices are managed by default by
  networkd in ubuntu-core, while wlan and wwan are managed by network-
  manager if installed. It would make sense to either assign a metric of
  100 in networkd configuration file or change network-manager snap so
  it handles ethernet in all cases when installed.

  [Test Case]
   * Set up an ethernet and wifi connection using netplan, and check metrics in "ip route". With the current version they have "1024", with the proposed update the ethernet one will have 100, the wifi one 600.

  [Regression Potential]
  It could in principle happen that someone relies on the current high metric and this interferes with some custom routing. However, netplan has only been used in snappy on xenial since recently, and there is no other official way to configure routing on snappy than netplan. So in practice this should be very low.
