Bug description:
  === Begin SRU Template ===
  [Impact]
  Without this fix applied, dns settings provided to the dhcp response
  in the initramfs are not reflected in the "real root".

  Thus dns resolution does not work. Of most interest was the MAAS use
  case of the 'root=http://<>/squashfs' use case.

  MAAS 2.3 uses this for the installation environment and also the rescue
  environment.  In most cases the 14.04 specific fix will only apply
  to installation as 16.04 is most likely to be used in rescue mode.

  [Test Case]
  There are two tests for this.

  a.) local/non-MAAS test
  Download the test case attached.
  Run it and follow the instructions.
  Login to the guest (ubuntu:password), and inspect /etc/resolv.conf
  without the fix there would be no data in /etc/resolv.conf.  With the
  fix you should see 'nameserver 10.0.2.2' and 'search mydomain.com bar.com'

  b.) MAAS test.
  For the full maas test, you need to build a image stream for maas
  with the fix included in the squashfs image and then import that
  stream to maas and use the rescue environment and verify dns.
  This process is beyond the scope of the SRU template, but is
  described partially in
    
http://bazaar.launchpad.net/~maas-images-maintainers/maas-images/maas-ephemerals/view/head:/README

  [Regression Potential]
  Regression potential should be very low.  There are gates in the code
  to make sure that this code is inactive other than when it is explicitly
  enabled.

  net-interface-handler will exit without doing anything unless:
  a.) there exist files /run/net-$INTERFACE.conf or /run/net6-$INTERFACE.conf
  and these files have non-empty values for a variable mentioned above.
  (These files are written by the initramfs code when 'ip=' is seen).

  b.) this is not a container.
    trusty uses 'running-in-container' to determine this.
    xenial uses 'systemd-detect-virt'

  c.) there is no OPENISCSI_MARKER file (/run/initramfs/open-iscsi.interface)
  if open-iscsi has written this file due to open-iscsi root, then it
  will handle this functionality. resolvconf will get out of the way.

  d.) /proc/cmdline contains cloud-config-url=* or 'rc-initrd-dns'
  This lowers the scope of changes in runtime to cases with where either the
  new flag is seen or cloud-config-url is passed. The MAAS use case will
  contain this flag.

  [Other Info]

  === End SRU Template ===

  Using MAAS 2.3, during commissioning (and likely in the rest of the
  ephemeral environment) we have noticed that resolv.conf is not set
  with the DNS server.

  That said, during the commissioning process, MAAS does not send any
  metadata to cloud-init to configure the network, rather, we expect the
  image to boot from the network via DHCP. So, cloud-init writes:

  ubuntu@manual:~$ cat /etc/network/interfaces.d/50-cloud-init.cfg
  # This file is generated from information provided by
  # the datasource.  Changes to it will not persist across an instance.
  # To disable cloud-init's network configuration capabilities, write a file
  # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
  # network: {config: disabled}
  auto lo
  iface lo inet loopback

  # control-manual ens3
  iface ens3 inet dhcp
  broadcast 192.168.122.255
  dns-nameservers 192.168.122.2
  gateway 192.168.122.1
  netmask 255.255.255.0

  Which correctly includes the DNS server. However:

Title:
  [2.3] resolv.conf is not set (during commissioning or testing)

Status in MAAS:
  Fix Committed
Status in resolvconf package in Ubuntu:
  Won't Fix
Status in resolvconf source package in Xenial:
  Fix Released

Bug description:
  === Begin SRU Template ===
  [Impact]
  Without this fix applied, dns settings provided to the dhcp response
  in the initramfs are not reflected in the "real root".

  Thus dns resolution does not work. Of most interest was the MAAS use
  case of the 'root=http://<>/squashfs' use case.  MAAS 2.3 uses this for
  the installation environment and also the rescue environment.

  [Test Case]
  There are two tests for this.

  a.) local/non-MAAS test
  Download the test case attached.
  Run it and follow the instructions.
  Login to the guest (ubuntu:password), and inspect /etc/resolv.conf
  without the fix there would be no data in /etc/resolv.conf.  With the
  fix you should see 'nameserver 10.0.2.2' and 'search mydomain.com bar.com'

  b.) MAAS test.
  For the full maas test, you need to build a image stream for maas
  with the fix included in the squashfs image and then import that
  stream to maas and use the rescue environment and verify dns.
  This process is beyond the scope of the SRU template, but is
  described partially in
    
http://bazaar.launchpad.net/~maas-images-maintainers/maas-images/maas-ephemerals/view/head:/README

  [Regression Potential]
  Regression potential should be very low.  There are gates in the code
  to make sure that this code is inactive other than when it is explicitly
  enabled.

  net-interface-handler will exit without doing anything unless:
  a.) there exist files /run/net-$INTERFACE.conf or /run/net6-$INTERFACE.conf
  and these files have non-empty values for a variable mentioned above.
  (These files are written by the initramfs code when 'ip=' is seen).

  b.) this is not a container.

  c.) there is no OPENISCSI_MARKER file (/run/initramfs/open-iscsi.interface)
  if open-iscsi has written this file due to open-iscsi root, then it
  will handle this functionality. resolvconf will get out of the way.

  d.) /proc/cmdline contains cloud-config-url=* or 'rc-initrd-dns'
  This lowers the scope of changes in runtime to cases with where either the
  new flag is seen or cloud-config-url is passed. The MAAS use case will
  contain this flag.

  [Other Info]

  === End SRU Template ===

  Using MAAS 2.3, during commissioning (and likely in the rest of the
  ephemeral environment) we have noticed that resolv.conf is not set
  with the DNS server.

  That said, during the commissioning process, MAAS does not send any
  metadata to cloud-init to configure the network, rather, we expect the
  image to boot from the network via DHCP. So, cloud-init writes:

  ubuntu@manual:~$ cat /etc/network/interfaces.d/50-cloud-init.cfg
  # This file is generated from information provided by
  # the datasource.  Changes to it will not persist across an instance.
  # To disable cloud-init's network configuration capabilities, write a file
  # /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
  # network: {config: disabled}
  auto lo
  iface lo inet loopback

  # control-manual ens3
  iface ens3 inet dhcp
  broadcast 192.168.122.255
  dns-nameservers 192.168.122.2
  gateway 192.168.122.1

2017-10-25 Thread Scott Moser

I updated some state on the tasks. As justification, this fix is in
resolvconf, so I dropped cloud-init. I had added it thinking it might
need integration, but it did not. Also marked the 'ubuntu' task as
"won't fix". The problem did not currently exist in Artful, and the
solution provided in resolvconf is not relevant there as resolvconf is
not used in Artful.
