iproute2 3.19.0 is stable on most important arches now, and also has the 
problem

If my git bisect went fine this is the commit where the command started 
returning nothing:

     ss: Filtering logic changing, with fixes

     This patch fixes some filtering combinations issues which does not
     work on the 'master' version:

         $ ss -4
         shows inet & unix sockets, instead of only inet sockets

         $ ss -u
         needs to specify 'state closed'

         $ ss src unix:*X11*
         needs to specify '-x' shortcut for UNIX family

         $ ss -A all
         shows only sockets with established states

     There might some other issues which was not observed.

     Also changed logic for calculating families, socket types and
     states filtering. I think that this version is a little simpler
     one. Now there are 2 predefined default tables which describes
     the following maping:

         family  -> (states, dbs)
         db      -> (states, families)

I have not used the ss command much, but this does indeed look like an 
iproute2 bug
