Bug description:
  [Impact]
  When a nic has a long enough name such that there is no space between the 
name and the ":" in /proc/net/igmp, ip maddr show dev  will miss the IPV4 
addresses which is otherwise shown with "ip maddr show".

  This is inconsistent behavior and can break scripts and tests, as
  shown in this bug's original description.

  Three patches from upstream were taken to fix this bug, and they were used 
individually instead of being merged into one single patch so it's easier to 
track and recognize authorship:
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=530903dd9003492edb0714e937ad4a5d1219e376
  
https://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git/commit/?id=b48a1161f5f9b6a0cda399a224bbbf72eba4a5c6

  [Test Case]
  * deploy the ubuntu release under test. Please use bare metal or a VM instead 
of containers, because the ip tool parses a file in /proc. Make sure iproute2 
is installed:
  sudo apt install iproute2

  * Run these commands to setup a dummy interface with a long name and
  an IPv4 address. Please change the address if it conflicts with a real
  network you might have available on that machine:

  sudo ip link add dummylongnic0 type dummy
  sudo ip addr add 192.168.199.10/24 dev dummylongnic0
  sudo ip link set dev dummylongnic0 up

  * Compare the output of these two commands with regards to the dummylongnic0 
interface:
  sudo ip maddr show
  sudo ip maddr show dev dummylongnic0

  * With the buggy iproute2 package installed, the more specific output "ip 
maddr show dev dummylongnic0" should lack the "inet 224.0.0.1" line:
  ip maddr show dev dummylongnic0
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet6 ff02::1
inet6 ff01::1

  
  Whereas the less specific command, which lists all interfaces, will have it 
listed for dummylongnic0:
  2:dummylongnic0
link  33:33:00:00:00:01
link  01:00:5e:00:00:01
inet  224.0.0.1
inet6 ff02::1
inet6 ff01::1

  
  * With the fixed iproute2 package, all dummylongnic0 addresses will be 
present in both outputs.

  
  [Regression Potential]
  In the end, the ip tool is parsing a text file produced by the kernel. As 
most parsing done in C, it's pretty low level and sensitive to changes in the 
file it's reading.

  [Other Info]
  I suggest to conduct the tests in VMs instead of containers (LXD) because the 
ip maddr command parses /proc/net/igmp, which is produced by the kernel. If you 
use a container, then it's the host's kernel that will be providing that file 
and it might not be the same as with the native kernel of that particular 
ubuntu release.

Bug description:
  [Impact]

   * An explanation of the effects of the bug on users and

   * justification for backporting the fix to the stable release.

   * In addition, it is helpful, but not required, to include an
 explanation of how the upload fixes this bug.

  [Test Case]

   * detailed instructions how to reproduce the bug

   * these should allow someone who is not familiar with the affected
 package to reproduce the bug and verify that the updated package fixes
 the problem.

  [Regression Potential]

   * discussion of how regressions are most likely to manifest as a
  result of this change.

   * It is assumed that any SRU candidate patch is well-tested before
 upload and has a low overall risk of regression, but it's important
 to make the effort to think about what ''could'' happen in the
 event of a regression.

   * This both shows the SRU team that the risks have been considered,
 and provides guidance to testers in regression-testing the SRU.

  [Other Info]
   
   * Anything else you think is useful to include
   * Anticipate questions from users, SRU, +1 maintenance, security teams and 
the Technical Board
   * and address these questions in advance

  
  --- Original description ---
  Attn. Canonical:  Please make sure that the existing iproute2 package gets 
updated with the two referenced patches as the missing information is impacting 
our standard test suites.

  Thanks.

  I found upstream already had patches that fix this problem:

  1) https://www.spinics.net/lists/netdev/msg415009.html
  commit 530903dd9003492edb0714e937ad4a5d1219e376
  Author: Petr Vorel

  ip: fix igmp parsing when iface is long

  Entries with long vhost names in /proc/net/igmp have no whitespace
  between name and colon, so sscanf() adds it to vhost and
  'ip maddr show iface' doesn't include inet result.

  Signed-off-by: Petr Vorel 

  2) https://www.spinics.net/lists/netdev/msg461479.html
  commit 21503ed2af233ffe795926f6641ac84ec1b15bf9
  Author: Michal Kubecek 
  Date:   Thu Oct 19 10:21:08 2017 +0200

  ip maddr: fix filtering by device

  Commit 530903dd9003 ("ip: fix igmp parsing when iface is long") uses
  variable len to keep trailing colon from interface name comparison.  This
  variable is local to loop body but we set it in one pass and use it in
  following one(s) so that we are actually using (pseudo)random length for
  comparison. This became apparent since commit b48a1161f5f9 ("ipmaddr: 
Avoid
  accessing uninitialized data") always initializes len to zero so that the
  name comparison is always true. As a result, "ip maddr show dev eth0" 
shows
  IPv4 multicast addresses for all interfaces.
