[Bug 1686784] Re: no predictable names for platform (non-PCI) NICs

 

This bug was fixed in the package systemd - 233-6ubuntu2

---------------
systemd (233-6ubuntu2) artful; urgency=medium

  [ Michael Biebl ]
  * basic/journal-importer: Fix unaligned access in get_data_size()
    (Closes: #862062)

  [ Dimitri John Ledkov ]
  * ubuntu: disable dnssec on any ubuntu releases (LP: #1690605)
  * Cherrypick upstream patch for vio predictable interface names.
  * Cherrypick upstream patch for platform predictable interface names.
    (LP: #1686784)

  [ Balint Reczey ]
  * Skip starting systemd-remount-fs.service in containers
    even when /etc/fstab is present.
    This allows entering fully running state even when /etc/fstab
    lists / to be mounted from a device which is not present in the
    container. (LP: #1576341)

Bug description:
  [Impact]
  Systems may have NICs attached to the "platform" bus. These are NICs that are onboard, but not attached to a PCI(-like) bus. Rather, they are described by firmware directly. None of the naming policies enabled by Ubuntu by default matches these NICs, so they end up having unpredictable names. In the case where other NICs are attached (e.g. PCIe cards), the ethN enumeration race occurs, making it impossible to have an interface name that is persistent across reboots. That is, if you do a network install over "eth0", on reboot that NIC now maybe "eth3", which causes it to fail to start the network on boot.

  The HiSilicon D05 boards are an example of this. It has 4 onboard NICs
  that are described by ACPI directly, and may also have other PCIe NICs
  plugged in.

  [Test Case]
  Boot a system with the characteristics described above, and check to see if any "ethN" interfaces exist.

  [Regression Risk]
  TBD - depends on the proposed solution.
