2012-08-30netfilter: add protocol independent NAT corePatrick McHardy1-12/+12
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 McHardy1-1/+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 McHardy1-1/+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 McHardy1-2/+2
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.

2011-10-31net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modulesPaul Gortmaker1-0/+1
These files are non modular, but need to export symbols using the macros now living in export.h -- call out the include so that things won't break when we remove the implicit presence of module.h from everywhere. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
2010-08-02netfilter: nf_nat: don't check if the tuple is unique when there isn't any other choiceChangli Gao1-2/+2
The tuple got from unique_tuple() doesn't need to be really unique, so the check for the unique tuple isn't necessary, when there isn't any other choice. Eliminating the unnecessary nf_nat_used_tuple() can save some CPU cycles too. Signed-off-by: Changli Gao <xiaosuo@gmail.com> Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-08-02netfilter: nf_nat: make unique_tuple return voidChangli Gao1-3/+3
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>
2008-04-14[NETFILTER]: nf_nat: use bool type in nf_nat_protoJan Engelhardt1-7/+7
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 McHardy1-1/+0
Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-04-14[NETFILTER]: nf_nat: move NAT ctnetlink helpers to nf_nat_proto_commonPatrick McHardy1-2/+2
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>
2008-01-31[NETFILTER]: nf_{conntrack,nat}_icmp: constify and annotateJan Engelhardt1-1/+1
Constify a few data tables use const qualifiers on variables where possible in the nf_conntrack_icmp* sources. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: nf_nat: mark NAT protocols constPatrick McHardy1-1/+1
Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: Convert old checksum helper namesPatrick McHardy1-2/+2
Kill the defines again, convert to the new checksum helper names and remove the dependency of NET_ACT_NAT on NETFILTER. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu1-5/+5
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>
2007-10-15[NETFILTER]: Do not copy skb in skb_make_writableHerbert Xu1-1/+1
Now that all callers of netfilter can guarantee that the skb is not shared, we no longer have to copy the skb in skb_make_writable. 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 McHardy1-2/+2
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>
2007-03-05[NETFILTER]: nf_conntrack/nf_nat: fix incorrect config ifdefsPatrick McHardy1-2/+1
The nf_conntrack_netlink config option is named CONFIG_NF_CT_NETLINK, but multiple files use CONFIG_IP_NF_CONNTRACK_NETLINK or CONFIG_NF_CONNTRACK_NETLINK for ifdefs. Fix this and reformat all CONFIG_NF_CT_NETLINK ifdefs to only use a line. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
