From af4c6641f5ad445fe6d0832da42406dbd9a37ce4 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 25 May 2012 13:42:45 -0600 Subject: net sched: Pass the skb into change so it can access NETLINK_CB cls_flow.c plays with uids and gids. Unless I misread that code it is possible for classifiers to depend on the specific uid and gid values. Therefore I need to know the user namespace of the netlink socket that is installing the packet classifiers. Pass in the rtnetlink skb so I can access the NETLINK_CB of the passed packet. In particular I want access to sk_user_ns(NETLINK_CB(in_skb).ssk). Pass in not the user namespace but the incomming rtnetlink skb into the the classifier change routines as that is generally the more useful parameter. Cc: Jamal Hadi Salim Acked-by: David S.
