Commit 6a328d8c6f03501657ad580f6f98bf9a42583ff7 changed the update
logic for the socket but it does not update the SCM_RIGHTS update
as well. This patch is based on the net_prio fix commit

48a87cc26c13b68f6cce4e9d769fcb17a6b3e4b8

     net: netprio: fd passed in SCM_RIGHTS datagram not set correctly

     A socket fd passed in a SCM_RIGHTS datagram was not getting
     updated with the new tasks cgrp prioidx. This leaves IO on
     the socket tagged with the old tasks priority.

     To fix this add a check in the scm recvmsg path to update the
     sock cgrp prioidx with the new tasks value.

Let's apply the same fix for net_cls.

Acutally I didn't report this. 

You made me look into this, so you reported it at least in my eyes :)

I was about to send exactly the same
patch and then I noticed the shared socket issue. ;)

I don't mind if you want your patch to be applied. I just felt
responsible for the changes I did.

thanks,
daniel
