net: net_cls: fd passed in SCM_RIGHTS datagram not set correctly
Commit 6a328d8c 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 48a87cc2 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. Signed-off-by:Daniel Wagner <daniel.wagner@bmw-carit.de> Reported-by:
