Indeed, the 3.13 and 3.16 -proposed kernels have the commit I'm
suspecting:

fib_rules: fix fib rule dumps across multiple skbs


The 3.19 -proposed kernel doesn't have it so I'm wondering if it's also affected.

Title:
  [regression] 3.13.0-69 infinite ip rules

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  When I run the 3.13.0-69 -proposed kernel on Trusty, I'm seeing
  infinite amount of ip rules:

  $ ip -f inet rule show | head
  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 
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 
  0:	from all lookup local 

  And it never stops:

  $ time ip -f inet rule show | wc -l
  ^C

  real	3m30.262s
  user	0m46.742s
  sys	3m39.516s

  Deleting the "lookup local" then shows an infinite amount of "lookup
  main".

  When I go back to 3.13.0-68, things look normal:

  $ time ip -f inet rule show
  0:	from all lookup local 
  32766:	from all lookup main 
  32767:	from all lookup default 

  real	0m0.002s
  user	0m0.000s
  sys	0m0.002s
