[Bug 1628306] Re: network booting fails for iscsi root if no ip is set

[Scott Moser]

** Description changed:

  [Impact]
  Remote-root installs (eg. / over iscsi and similar) where the configuration 
is simple, and no extra parameters are included on the kernel command-line (as 
opposed to MaaS specifying everything).
  
  [Test case]
  1) do an installation with /boot on a local disk and / and swap over a remote 
LUN (iSCSI is simple to do).
  2) Update to initramfs-tools with isc-dhcp support.
  
  [Regression potential]
  This is in itself a fix for a regression found in initramfs-tools 
(0.125ubuntu4 on yakkety, or 0.122ubuntu8.2 on xenial). Failure to boot on a 
remote root filesystem would constitue a regression.
+ 
+ [Regressions]
+  bug 1631474: No networking with initramfs-tools 0.122ubuntu8.3 and ip=dhcp 
boot option 
  
  --
  
  I did a new install with /boot on /dev/sda, and everything else (/ and
  swap) on an iSCSI LUN.
  
  Booting this with initramfs-tools using ipconfig works without issues.
  
  Booting this with initramfs-tools (0.125ubuntu4 on yakkety, or
  0.122ubuntu8.2 on xenial) fails because no interface is specified.
  
  This appears to be because ipconfig interprets "" as meaning to try
  every interface until one works (or all fail), whereas calling dhclient
  without an interface name simply returns a failure.

[Bug 1628306] Re: network booting fails for iscsi root if no ip is set

[scotte]

initramfs-tools 0.122ubuntu8.3 has resulted in a serious regression for
instances running in AWS when the ip=dhcp boot option set.
0.122ubuntu8.2 (and previous versions) do not exhibit the problem.

I'll create a new issue for tracking, but wanted to add a comment here.

This bug was fixed in the package initramfs-tools - 0.122ubuntu8.3

initramfs-tools (0.122ubuntu8.3) xenial; urgency=medium

  * scripts/functions: make sure we can try to start all available and suitable
interfaces if ip= isn't set when setting up the network, and exit as soon
as we get an IP address. This retains the old behavior from ipconfig when
ip= is unset, for really simple remote-root scenarios. (LP: #1628306)
  * scripts/functions: retain bootp/rarp behavior using ipconfig.

[Bug 1628306] Re: network booting fails for iscsi root if no ip is set

[Steve Langasek]

Hello Mathieu, or anyone else affected,

Accepted initramfs-tools into xenial-proposed. The package will build
now and be available at https://launchpad.net/ubuntu/+source/initramfs-
tools/0.122ubuntu8.3 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 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!
