Kernel version 3.16.0-53.

This may be the same as bug #1514785, which I found after submitting
this bug.  The other bug has lots of comments about which kernels are
affected.

Title:
  ip rule show/list runs on and on after software update

Status in iproute2 package in Ubuntu:
  New

Bug description:
  I have the iproute2 package installed on a 14.04 LTS system.
  Everything was operating just fine.  I had not done a software update
  in a while.  I used the Software Updater from Dash and updated the
  system.  It updated a couple hundred megabytes.  The update completed
  without error (as far as I know).  It said a reboot was needed.  So I
  rebooted.

  After that, I had problems.

  Specifically, when I type "ip rule list", the output runs on and on and on, seemingly without end.
  0:	from all lookup local 
  0:	 from all lookup local 
  0:	 from all lookup local 
  0:  	from all lookup local 
  0:	 from all lookup local 
  0:    from all lookup local 
  ...

  I tried "ip rule flush" which seems to hang.
  I was eventually able to clear out the rules with:
  ip rule del pref 0
  ip rule del pref 32766
  ip rule del pref 32767

  But that leaves me without even the 3 standard rules, which are:
  0:	from all lookup local 
  32766:	from all lookup main 
  32767:	from all lookup default

  So I need to add those back
  But as soon as I try to add the first of the 3 standard ip rules, the problem occurs again:
  ip rule add from all table local pref 0
  ip rule list
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 
  ...

  The same thing occurs if I try to add any of the other standard rules.

  I tried updating a second 14.04 LTS machine.  The same thing happened
  to that one.

  Now what?
