[NETFILTER]: x_tables: per-netns xt_tables In fact all we want is per-netns set of rules, however doing that will unnecessary complicate routines such as ipt_hook()/ipt_do_table, so make full xt_table array per-netns. Every user stubbed with init_net for a while. Signed-off-by: Alexey Dobriyan <adobriyan@sw.ru> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

netfilter: don't pull include/linux/netfilter.h from netns headers This pulls the full hook netfilter definitions from all those that include net_namespace.h. Instead let's just include the bare minimum required in the new linux/netfilter_defs.h file, and use it from the netfilter netns header files. I also needed to include in.h and in6.h from linux/netfilter.h otherwise we hit this compilation error: In file included from include/linux/netfilter_defs.h:4:0, from include/net/netns/netfilter.h:4, from include/net/net_namespace.h:22, from include/linux/netdevice.h:43, from net/netfilter/nfnetlink_queue_core.c:23: include/uapi/linux/netfilter.h:76:17: error: field ‘in’ has incomplete type struct in_addr in; And also explicit include linux/netfilter.h in several spots.

netfilter: xt_CT: recover NOTRACK target support Florian Westphal reported that the removal of the NOTRACK target (9655050 netfilter: remove xt_NOTRACK) is breaking some existing setups. That removal was scheduled for removal since long time ago as described in Documentation/feature-removal-schedule.txt What: xt_NOTRACK Files: net/netfilter/xt_NOTRACK.c When: April 2011 Why: Superseded by xt_CT Still, people may have not notice / may have decided to stick to an old iptables version. I agree with him in that some more conservative approach by spotting some printk to warn users for some time is less agressive. Current iptables 1.4.16.3 already contains the aliasing support that makes it point to the CT target, so upgrading would fix it. Still, the policy so far has been to avoid pushing our users to upgrade. As a solution, this patch recovers the NOTRACK target inside the CT target and it now spots a warning.

netfilter: ipt_CLUSTERIP: deprecate it in favour of xt_cluster xt_cluster supersedes ipt_CLUSTERIP since it can be also used in gateway configurations (not only from the backend side). ipt_CLUSTER is also known to leak the netdev that it uses on device removal, which requires a rather large fix to workaround the problem: http://patchwork.ozlabs.org/patch/358629/ So let's deprecate this so we can probably kill code this in the future.
