2016-11-03netfilter: x_tables: move hook state into xt_action_param structurePablo Neira Ayuso
Place pointer to hook state in xt_action_param structure instead of copying the fields that we need. After this change xt_action_param fits into one cacheline. This patch also adds a set of new wrapper functions to fetch relevant hook state structure fields. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2015-09-18netfilter: x_tables: Pass struct net in xt_action_paramEric W. Biederman
As xt_action_param lives on the stack this does not bloat any persistent data structures. This is a first step in making netfilter code that needs to know which network namespace it is executing in simpler. Signed-off-by: "Eric W.

2015-06-18net: sched: Simplify em_ipset_matchEric W. Biederman
em->net is always set and always available, use it in preference to dev_net(skb->dev). Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2015-01-13net: sched: fix skb->protocol use in case of accelerated vlan pathJiri Pirko
tc code implicitly considers skb->protocol even in case of accelerated vlan paths and expects vlan protocol type here. However, on rx path, if the vlan header was already stripped, skb->protocol contains value of next header. Similar situation is on tx path. So for skbs that use skb->vlan_tci for tagging, use skb->vlan_proto instead.

2014-10-06net: sched: remove tcf_proto from ematch callsJohn Fastabend
This removes the tcf_proto argument from the ematch code paths that only need it to reference the net namespace. This allows simplifying qdisc code paths especially when we need to tear down the ematch from an RCU callback. In this case we can not guarentee that the tcf_proto structure is still valid.

2013-10-18em_ipset: use dev_net() accessorstephen hemminger
Randy found that if network namespace not enabled then nd_net does not exist and would cause compilation failure. This is handled correctly by using the dev_net() macro.

2013-09-30netfiler: ipset: Add net namespace for ipsetVitaly Lavrov
This patch adds netns support for ipset. Major changes were made in ip_set_core.c and ip_set.h. Global variables are moved to per net namespace. Added initialization code and the destruction of the network namespace ipset subsystem. In the prototypes of public functions ip_set_* added parameter "struct net*". The remaining corrections related to the change prototypes of public functions ip_set_*.

2013-04-29netfilter: ipset: Introduce extensions to elements in the coreJozsef Kadlecsik
Introduce extensions to elements in the core and prepare timeout as the first one. This patch also modifies the em_ipset classifier to use the new extension struct layout. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-07-12net: sched: add ipset ematchFlorian Westphal
Can be used to match packets against netfilter ip sets created via ipset(8). skb->sk_iif is used as 'incoming interface', skb->dev is 'outgoing interface'. Since ipset is usually called from netfilter, the ematch initializes a fake xt_action_param, pulls the ip header into the linear area and also sets skb->data to the IP header (otherwise matching Layer 4 set types doesn't work).
