This bug is a regression of changes made under bug 1628306. Bug 1628306
never updated 14.04, so this bug doesn't affect (and never affected)
14.04. If you have a problem with the behaviour of ip=dhcp in 14.04,
please file a separate and full bug report.

  Original Bug Description Follows==

  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

[Mathieu Trudel-Lapierre]

AFAIK everything landed for this already in zesty (and thus in artful as
well). Not sure why it is still "In Progress".

I'm setting this to Fix Released; if there are any other issues anyway,
they should get their own bug so we can better track any possible SRUs.

[Launchpad Bug Tracker]

This bug was fixed in the package initramfs-tools - 0.125ubuntu6.3

---
initramfs-tools (0.125ubuntu6.3) yakkety; urgency=medium

  * Do not rely on debug variables from dhclient.

initramfs-tools (0.125ubuntu6.2) yakkety; urgency=medium

  [ Mathieu Trudel-Lapierre ]
  * scripts/functions: for configure_networking:
- split out IPv6 options in its own cmdline parameter: ip6= ; always use
  dhclient in this case if the value set is anything other than 'off' or
  'none'. Furthermore, parse anything other than 'on', 'dhcp' or 'any' as
  the name of an interface. (LP: #1621507)
- rework the stop conditions so that we properly handle the ROUNDTTT loop,
  timing out after a short period of time and trying again after a short
  sleep.
- add a 'done' parameter for both ip= and ip6= so that we can properly
  exit the ROUNDTTT loop once we know that either there is no work to do,
  or that we've achieved what we wanted (that is, to bring up IPv4, IPv6,
  or possibly both).
- return ip=dhcp to the ipconfig use case; if set, then ipconfig will be
  run using any interface available, or the BOOTIF if it was set.

  [ LaMont Jones ]
  * Only source ipv4 config in configure_networking() if it exists.

initramfs-tools (0.125ubuntu6.1) yakkety; urgency=medium

  * scripts/functions: Revert configure_networking changes to the state at
0.125ubuntu3. (LP: #1631474)

initramfs-tools (0.125ubuntu6) yakkety; urgency=medium

  * Fix case where ip=dhcp and ip=:eth0 and other ip= instances exists on
the kernel command line (LP: #1631474)
  * Also fixed an error discovered by the shellcheck static code analyzer
where "$DEVICES" would be processed as a single device where-as removing
the quotes allows the list to be correctly processed by the for loop.

Hello scotte, or anyone else affected,

Accepted initramfs-tools into yakkety-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/initramfs-
tools/0.125ubuntu6.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

This is confusing. Yakkety has never (to date) had an SRU land. So the
proposed revert to Yakkety isn't actually a revert from Yakkety's
perspective. Doing so would mean a behavioural change to Yakkety users,
no?

  [Impact]
   * initramfs-tools SRUs introduced regressions in ip= syntax, which cause 
unexpected behavior

  [Test Case]
   * Create a machine that boots using an nfsroot.
   * Use ip=:eth0:dhcp on the kernel command line.  To set up
     networking.
   * Discover that the device never comes up because, networking is not 
configured correctly.

  [Regression Potential]
  Should be back to original behavior before ipv6 support was introduced in the 
past 2 or 3 SRUs.

  [Other Info]

   * There are a number of other issues in this code base that are not solved 
by this fix.
     - The ?*:?*:?*:?*: use case falls through to the default case, and likely 
breaks there.  As such static assignment via ip= appears broken
     -
   * The networking configuration does not strictly follow the kernel 
documentation as described 
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This 
should be fixed.

  This bug is a regression of changes made under bug 1628306.

  Original Bug Description Follows==

  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

Mathieu,

I tested your PPA package with Xenial: with no config changes on my end,
it's working as expected from my use case.

Thanks!

enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

This bug was fixed in the package initramfs-tools - 0.125ubuntu6

initramfs-tools (0.125ubuntu6) yakkety; urgency=medium

  * Fix case where ip=dhcp and ip=:eth0 and other ip= instances exists on
the kernel command line (LP: #1631474)
  * Also fixed an error discovered by the shellcheck static code analyzer
where "$DEVICES" would be processed as a single device where-as removing
the quotes allows the list to be correctly processed by the for loop.

  [Impact]

   * 0.122ubuntu8.3 of initramfs-tools no longer correctly processed
  ip=dhcp or ip=:eth0:dhcp

   * Regression-updates

   * The fix better parses the ip= command line argument.

  [Test Case]

   * Create a machine that boots using an nfsroot.

   * Use ip=:eth0:dhcp on the kernel command line.  To set up
     networking.

   * Discover that the device never comes up because, networking is not
  configured correctly.

  [Regression Potential]

   * Regressions potential is limited to machines using
  ip={""|*|on|any|dhcp} on the kernel command line.  As this is
  already broken regression potential is minimal.  This is common on
  machines that use nfsroot or otherwise pxe boot.

  [Other Info]

   * There are a number of other issues in this code base that are not solved 
by this fix.
     - The ?*:?*:?*:?*: use case falls through to the default case, and likely 
breaks there.  As such static assignment via ip= appears broken
     -
   * The networking configuration does not strictly follow the kernel 
documentation as described 
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This 
should be fixed.

  This bug is a regression of changes made under bug 1628306.

  Original Bug Description Follows==

  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

I have confirmed that this functions as expected for MAAS (behaves
exactly like 0.122ubuntu8.1 did.)  Not marking verification-done, but +1

[Jason Gerard DeRose]

Okay, tested 0.122ubuntu8.5 from xenial-proposed, and it fixes the issue
for my use-case.

But I'm not changing verification-needed to verification-done yet as I
don't know if it fixes the use case of the original reporter.

@scotte - can you please confirm whether this fixes things for you?

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[Mathieu Trudel-Lapierre]

Seems to me like we're at the point where considering a straight revert
of the SRU would be in order (and I'm certainly considering it for the
short term), in order to move forward again at a later time when this is
more solid -- not that the end goal is still going to be happening
(though maybe not in 16.04), that is to gradually remove klibc from the
initramfs. That *will* require changes, such as we see here. If you
never fail, it's because you're not innovating...

The changes here were motivated by providing IPv6 support for MaaS
deployments in v6-only and mixed networks.

>From my understanding of things, we've now fixed (in 0.122ubuntu8.4) the
issues with ip=dhcp and some other ip= forms being parsed incorrectly.

There are still two outstanding issues:
 - boot speed (I suspect there is only a limited amount of things we can do 
about this, given the use of dhclient).
 - "portfast behavior", which is how we handle delays in getting a response 
from a DHCP server. There was definitely a regression there, for which I have a 
fix in my ppa at ppa:cyphermox/maas.

Are there any other outstanding issues? If so, what kernel command-line
are you using, and please include the exact messages on screen (or in
logs) so we can know what we're dealing with.

0.122ubuntu8.4 still fails to get an IP when the switchport is not
'portfast' (and the switch therefore passes no traffic for 60 seconds
after link-up.)

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[scotte]

smoser - I think you make a really good point. A regression in an LTS
distribution that results in a working configuration to no longer work
is fairly serious - as is introducing behavioral changes in an LTS.
While I'm generally in favor of fix-forward, it's not always the right
approach. I acknowledge changes are hard, and there's not always a clear
or right answer, especially given the vast diversity in exactly what
people do with their systems and how they configure them. This is a
larger discussion around change management, and my opinions here are a
bit off-topic as it relates specifically to this bug, so...

I retested with xenial-proposed and the system rebooted fine for me.

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[Jason Gerard DeRose]

@martin - I tested the proposed package, and it's workable, but there
are behavior changes still compared to prior to when this regression was
introduced (in particular, the boot is a lot slower when there are
mulitple NICs but only one will be configured, even when I use
"ip=:eth0:dhcp").

@scott - I think I agree with you. Considering this is an SRU for the
LTS, I'd prefer that as little behavior change be introduced as
possible.

  [Impact]

   * 0.122ubuntu8.3 of initramfs-tools no longer correctly processed

   * Regression-updates

   * The fix better parses the ip= command line argument.

  [Test Case]

   * Create a machine that boots using an nfsroot.

   * Use ip=:eth0:dhcp on the kernel command line.  To set up
     networking.

   * Discover that the device never comes up because, networking is not
  configured correctly.

  [Regression Potential]

   * Regressions potential is limited to machines using
  ip={""|*|on|any|dhcp} on the kernel command line.  As this is
  already broken regression potential is minimal.  This is common on
  machines that use nfsroot or otherwise pxe boot.

  [Other Info]

by this fix.
     - The ?*:?*:?*:?*: use case falls through to the default case, and likely 
breaks there.  As such static assignment via ip= appears broken
     -
   * The networking configuration does not strictly follow the kernel 
documentation as described 
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This 
should be fixed.

  Original Bug Description Follows==

  initramfs-tools 0.122ubuntu8.3 introduced a serious regression where
  networking is not initialized when the boot option "ip=dhcp" is
  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[Scott Moser]

Hi,
I think the right way to fix this regression would have been to revert the 
change.
The change made in bug 1628306 made fairly wide spread changes.  It caused this 
regression as seen, but also added behavioral changes.

Previously, 'ip=dhcp' would do a ipv4 dhcp request (via ipconfig).
The change was:
a.) to make it use dhclient
b.) to *also* do a dhcpv6 request in all cases.

Note: I accepted this into -proposed as 'ip: ether "dev" is duplicate,
or "permanent" is garbage' seems to be an unrelated bug. Of course feel
free to fix that one as well with a subsequent upload, but this still
appears to be an incremental fix as-is.

Attaching a tarbal of everything i have in /var/log, not sure it's
useful (not my "ephemeral" environment is read-only with /var/log on a
tmpfs, so it's mostly empty).

Also here's my exact /proc/cmdline from within the booted ephemeral
environment:

BOOT_IMAGE=vmlinuz-4.4.0-42-generic initrd=initrd.img-4.4.0-42-generic

@chiluk - I tested the latest package in your PPA, but something seems
slightly wonky for my use case.

Networking seems to come up correctly, but it takes longer than it
should and I see warnings like this repeated several times:

ip: ether "dev" is duplicate, or "permanent" is garbage

  provided. We are seeing this problem in AWS, but cannot confirm if
  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

  [Impact]

   * 0.122ubuntu8.3 of initramfs-tools no longer correctly processed

   * Discover that the device never comes up because, networking is not

  [Regression Potential]

   * Regressions potential is limited to machines using

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[Dave Chiluk]

I have uploaded a new version of initramfs-tools to my ppa, I would
again appreciate testing on this.  Notably I fixed an bug that was
causing all_netbootable_devices to be tried instead of the interface
specified on the command line.

I also now handle the case where ip=:bootif , which really shouldn't
be a concern to most.

I still think ip=bootif might fail *(if /run/net-${DEVICE}.conf does not
exist), but as this is an anaconda use case and not a mainline kernel
use case I'll ignore it for the purpose of the SRU.

  this issue is specific to AWS or will occur with different hardware or
  in different environments.

  Removing "ip=dhcp" from the boot options with 0.122ubuntu8.3 results
  in networking being configured.

  The issue does not occur with 0.122ubuntu8.2 or previous versions when
  "ip=dhcp" is set.

  AWS has no console so debugging is not a trivial task. I do have a
  console log with some output, and will update this bug shortly with
  it.

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[gregory]

I also have had four computers in the last 2 days show this bug.

I reinstalled the OS in those cases, if I find the bug again, I'll test
the PPA.

Thanks for finding a fix!

  [Impact]

   * 0.122ubuntu8.3 of initramfs-tools no longer correctly processed
  ip=dhcp or ip=:eth0:dhcp

   * Regression-updates

   * The fix better parses the ip= command line argument.

  [Test Case]

   * Create a machine that boots using an nfsroot.

   * Use ip=:eth0:dhcp on the kernel command line.  To set up
 networking.

   * Discover that the device never comes up because, networking is not
  conifgured correctly.

  [Regression Potential]

   * Regressions potential is limited to machines using
  ip={""|*|on|any|dhcp} on the kernel command line.  As this is
  already broken regression potential is minimal.

  [Other Info]
   
   * There are a number of other issues in this code base that are not solved 
by this fix.
   * The networking configuration does not strictly follow the kernel 
documentation as described 
https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt . This

[Touch-packages] [Bug 1631474] Re: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp boot option

[scotte]

I tested with the PPA and it looks good in an initial test. Before,
upgrading initramfs-tools and rebooting would result in AWS instance
being unreachable. Now, it looks good!

$ cat /proc/cmdline
root=LABEL=cloudimg-rootfs ro console=hvc0 ip=dhcp tsc=reliable 

$ dpkg -l|grep initramfs-tools
ii  initramfs-tools  0.122ubuntu8.3+lp1631474all

[Dave Chiluk]

I created a PPA with a proposed solution to this issue.  If I could get
some testing with this ppa I would appreciate it.  Additionally if you
test the ppa please report back and include your /proc/cmdline in your
comment.

Thank you,

As asked by chiluk on IRC, here's my PXE boot configuration (well,
representative one anyway, the exact kernel version will obviously
change):

Here's the initial portion of console output, with only a couple of
minor redactions related to keys, hostname, MAC address.

The most important bit is:

ip: SIOCGIFFLAGS: No such device
Error getting hardware address for "dhcp": No such device

Where the "ip=dhcp" kernel is not being processed correctly per kernel
documentation - see
