Subject: iproute2 regression -- ss -u returns an empty list

Hi,

Following up a bug report I received at
http://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=799 it looks like the current
version iproute2's ss utility always returns an empty result set whenever
specifying the -u flag.

The problem has been bisected to 9db7bf15e22b6a1b8bc09c4a1e29571cbca55c94 and is
also affecting version 3.19.0, but most notably 4.0.0+.

I'm not quite sure that's the correct commit, but it does definitely look related.

Even ss -xu, which previously returned a list of UNIX and UDP sockets now
returns nothing on my systems.

Any help with that matter is greatly appreciated.

Mihai
