We need to use rcu_assign_pointer/rcu_dereference to avoid races. Also remove an obsolete CONFIG_IP_NAT_NEEDED ifdef. Signed-off-by:

Currently we return EINVAL for "instance exists", "allocation failed" and "module unloaded below us", which is completely inapproriate. Signed-off-by:

Similar to the nfnetlink_queue fixes: The peer_pid must be checked in all cases when a logging instance exists, additionally we must check whether an instance exists before attempting to configure it to avoid NULL ptr dereferences. Signed-off-by:

Whatever that comment tries to say, I don't get it and it looks like a leftover from the time when RCU wasn't used properly. Signed-off-by:

nf_nat_setup_info gets the hook number and translates that to the manip type to perform. This is a relict from the time when one manip per hook could exist, the exact hook number doesn't matter anymore, its converted to the manip type. Most callers already know what kind of NAT they want to perform, so pass the maniptype in directly. Signed-off-by:

This patch adds support for master tuple event notification and dumping. Conntrackd needs this information to recover related connections appropriately. Signed-off-by:

Pablo Neira Ayuso authored
The combination of NAT and helpers may produce TCP sequence adjustments. In failover setups, this information needs to be replicated in order to achieve a successful recovery of mangled, related connections. This patch is particularly useful for conntrackd, see: http://people.netfilter.org/pablo/conntrack-tools/Signed-off-by:

When terminating DSL connections for an assortment of random customers, I've found it necessary to use iptables to clamp the MSS used for connections to work around the various ICMP blackholes in the greater net. Unfortunately, the current behaviour in Linux is imperfect and actually make things worse, so I'm proposing the following: increasing the MSS in a packet can never be a good thing, so make --set-mss only lower the MSS in a packet. Yes, I am aware of --clamp-mss-to-pmtu, but it doesn't work for outgoing connections from clients (ie web traffic), as it only looks at the PMTU on the destination route, not the source of the packet (the DSL interfaces in question have a 1442 byte MTU while the destination ethernet interface is 1500 -- there are problematic hosts which use a 1300 byte MTU). Reworking that is probably a good idea at some point, but it's more work than this is. Signed-off-by:

Reformat ip_tables.c and ip6_tables.c in order to eliminate non-functional differences and minimize diff output. This allows to get a view of the real differences using: sed -e 's/IP6T/IPT/g' \ -e 's/IP6/IP/g' \ -e 's/INET6/INET/g' \ -e 's/ip6t/ipt/g' \ -e 's/ip6/ip/g' \ -e 's/ipv6/ip/g' \ -e 's/icmp6/icmp/g' \ net/ipv6/netfilter/ip6_tables.c | \ diff -wup /dev/stdin net/ipv4/netfilter/ip_tables.c Signed-off-by: -
