[X2Go-Dev] Bug#799: Same problem in Gentoo

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:

commit 9db7bf15e22b6a1b8bc09c4a1e29571cbca55c94 Author: Vadim Kochan <vadim4j@gmail.com> Date: Sun Jan 4 22:18:40 2015 +0200

 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
