2012-08-30netfilter: add protocol independent NAT corePatrick McHardy1-67/+0
Convert the IPv4 NAT implementation to a protocol independent core and address family specific modules. Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-12-23netfilter: ctnetlink: remove dead NAT codePatrick McHardy1-5/+0
The NAT range to nlattr conversation callbacks and helpers are entirely dead code and are also useless since there are no NAT ranges in conntrack context, they are only used for initially selecting a tuple. The final NAT information is contained in the selected tuples of the conntrack entry. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2011-12-23netfilter: nat: remove module reference counting from NAT protocolsPatrick McHardy1-2/+0
The only remaining user of NAT protocol module reference counting is NAT ctnetlink support. Since this is a fairly short sequence of code, convert over to use RCU and remove module reference counting. Module unregistration is already protected by RCU using synchronize_rcu(), so no further changes are necessary.

2011-12-23netfilter: nf_nat: export NAT definitions to userspacePatrick McHardy1-7/+7
Export the NAT definitions to userspace. So far userspace (specifically, iptables) has been copying the headers files from include/net. Also rename some structures and definitions in preparation for IPv6 NAT. Since these have never been officially exported, this doesn't affect existing userspace code.

2010-10-04netfilter: nf_nat: make find/put staticStephen Hemminger1-3/+0
The functions nf_nat_proto_find_get and nf_nat_proto_put are only used internally in nf_nat_core. This might break some out of tree NAT module. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-08-02netfilter: nf_nat: make unique_tuple return voidChangli Gao1-4/+4
The only user of unique_tuple() get_unique_tuple() doesn't care about the return value of unique_tuple(), so make unique_tuple() return void (nothing). Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
2009-11-04net: cleanup include/netEric Dumazet1-2/+1
This cleanup patch puts struct/union/enum opening braces, in first line to ease grep games. struct something { becomes : struct something { Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-04-14[NETFILTER]: nf_nat: use bool type in nf_nat_protoJan Engelhardt1-21/+21
Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: remove unused name from struct nf_nat_protocolPatrick McHardy1-3/+0
Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: move NAT ctnetlink helpers to nf_nat_proto_commonPatrick McHardy1-4/+4
Move to nf_nat_proto_common and rename to nf_nat_proto_... since they're also used by protocols that don't have port numbers. Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: add helpers for common NAT protocol operationsPatrick McHardy1-0/+11
Add generic ->in_range and ->unique_tuple ops to avoid duplicating them again and again for future NAT modules and save a few bytes of text: net/ipv4/netfilter/nf_nat_proto_tcp.c: tcp_in_range | -62 (removed) tcp_unique_tuple | -259 # 271 -> 12, # inlines: 1 -> 0, size inlines: 7 -> 0 2 functions changed, 321 bytes removed net/ipv4/netfilter/nf_nat_proto_udp.c: udp_in_range | -62 (removed) udp_unique_tuple | -259 # 271 -> 12, # inlines: 1 -> 0, size inlines: 7 -> 0 2 functions changed, 321 bytes removed net/ipv4/netfilter/nf_nat_proto_gre.c: gre_in_range | -62 (removed) 1 function changed, 62 bytes removed vmlinux: 5 functions changed, 704 bytes removed Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-01-28[NETFILTER]: nf_nat: mark NAT protocols constPatrick McHardy1-9/+9
Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu1-1/+1
With all the users of the double pointers removed, this patch mops up by finally replacing all occurances of sk_buff ** in the netfilter API by sk_buff *. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[NETFILTER]: nfnetlink: rename functions containing 'nfattr'Patrick McHardy1-4/+4
There is no struct nfattr anymore, rename functions to 'nlattr'. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-10[NETFILTER]: nfnetlink: convert to generic netlink attribute functionsPatrick McHardy1-2/+2
Get rid of the duplicated rtnetlink macros and use the generic netlink attribute functions. The old duplicated stuff is moved to a new header file that exists just for userspace. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-12-02[NETFILTER]: Add NAT support for nf_conntrackJozsef Kadlecsik1-0/+70
Add NAT support for nf_conntrack. Joint work of Jozsef Kadlecsik, Yasuyuki Kozakai, Martin Josefsson and myself. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
