* [NETFILTER]: x_tables: error if ip_conntrack is asked to handle IPv6 packetsYasuyuki Kozakai2006-12-131-6/+2
| | | | | | | | | | To do that, this makes nf_ct_l3proto_try_module_{get,put} compatible functions. As a result we can remove '#ifdef' surrounds and direct call of need_conntrack().

* [NETFILTER]: Rename init functions.Andrew Morton2006-03-281-4/+4
| | | | | | | | | | | | | | Every netfilter module uses `init' for its module_init() function and `fini' or `cleanup' for its module_exit() function. Problem is, this creates uninformative initcall_debug output and makes ctags rather useless. So go through and rename them all to $(filename)_init and $(filename)_fini.

* [NETFILTER]: nf_conntrack: support for layer 3 protocol load on demandPablo Neira Ayuso2006-03-221-0/+17
| | | | | | | | | | | | | | x_tables matches and targets that require nf_conntrack_ipv[4|6] to work don't have enough information to load on demand these modules. This patch introduces the following changes to solve this issue: o nf_ct_l3proto_try_module_get: try to load the layer 3 connection tracker module and increases the refcount. o nf_ct_l3proto_module put: drop the refcount of the module.

* [NETFILTER] nf_conntrack: clean up to reduce size of 'struct nf_conn'Harald Welte2006-03-201-3/+5
| | | | | | | | | | | | | | | | | | | | This patch moves all helper related data fields of 'struct nf_conn' into a separate structure 'struct nf_conn_help'. This new structure is only present in conntrack entries for which we actually have a helper loaded. Also, this patch cleans up the nf_conntrack 'features' mechanism to resemble what the original idea was: Just glue the feature-specific data structures at the end of 'struct nf_conn', and explicitly re-calculate the pointer to it when needed rather than keeping pointers around. Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack is 276 bytes. We still need to save another 20 bytes in order to fit into to target of 256bytes.

* [NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tablesHarald Welte2006-01-121-0/+188
This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.
