[Bug 1714933] Re: Xenial: Please roll SRU with upstream fix for networkd to "accept colons in network interface names"

 

This bug was fixed in the package systemd - 232-21ubuntu7

---------------
systemd (232-21ubuntu7) zesty; urgency=medium

  * networkd: accept `:' in ifnames in systemd/networkd. (LP: #1714933)
  * networkd: add support for ActiveSlave and PrimarySlave netdev options.
    (LP: #1709135)
  * Cherrypick upstream fix for a race between .mount and .automount units,
    which currently may result in automounts hanging. (LP: #1709649)
  * systemd.postinst: Fix-up version number check in the previous sru.
    The version check in the postinst was too tight, thus the SRU fix failed
    validation. (LP: #1710410)

systemd (232-21ubuntu6) zesty; urgency=medium

  * link: Fix offload features initialization.
    This fixes a regression introduced in v232 which caused TCP
    segmentation offloads being disabled by default, resulting in
    significant performance issues under certain conditions. (Closes: #864073)
    (LP: #1703393)
  * loginctl: Fix loginctl ignoring user given session IDs at command-line
    (LP: #1682154)
  * Disable fallback DNS servers.
    This causes resolved to call-home to google, attempt to access network when
    none is available, and spams logs. (LP: #1449001)
  * initramfs-tools: trigger udevadm add actions with subsystems first.
    This updates the initramfs-tools init-top udev script to trigger udevadm
    actions with type specified. This mimicks the
    systemd-udev-trigger.service. Without type specified only devices are
    triggered, but triggering subsystems may also be required and should happen
    before triggering the devices. This is the case for example on s390x with zdev
    generated udev rules. (LP: #1713536)
  * Enable systemd-resolved by default. (LP: #1710410)
  * core: fix systemd failing to serialize tasks correctly on daemon-reload.
    (LP: #1702823)

Bug description:
  [Impact]
  networkd cannot manage interface names with ':' in them. As used commonly, by convention, by other tools.

  [Fix]
  Update networkd validation routines and test-suites to accept network interface names with ':' in it.

  [Testcase]
  Create an inteface with ':' in its name and use it anywhere where systemd validates ifname. E.g. Socket BindToDevice definition, nspawn network zone info, Label= in [Address] section in networkd.

  [Regression Potential]
  This fix will change validation routines, and thus commands or settings that were previously rejected or ignored will now take effect. Specifically Label= settings in networkd may lead to networking conflicts. The justification for this change is that networkd should really use the sensible ':' ifnames that the user is requesting systemd to use.

  [Original Bug Reprot]
  PR: https://github.com/systemd/systemd/pull/5117

  issue: https://github.com/systemd/systemd/issues/4057

  Before the networkd from 231 was backported, it was possible to use
  interface alias names that contained a colon, e.g. eth0:1. This is
  commonly used to make legacy tools like "ifconfig" work, because they
  *expect* a colon in the interface name.

  Martin told me to file a bug for this.

  Merging networkd from 231 lead to a regression where valid configs
  were not accepted anymore after the backport. Please merge that fix
  for the regression.
