commit d6d3f08b (netfilter: xtables: conntrack match revision 2) does break the v1 conntrack match iptables-save output in a subtle way. Problem is as follows: up = kmalloc(sizeof(*up), GFP_KERNEL); [..] /* * The strategy here is to minimize the overhead of v1 matching, * by prebuilding a v2 struct and putting the pointer into the * v1 dataspace. */ memcpy(up, info, offsetof(typeof(*info), state_mask)); [..] *(void **)info = up; As the v2 struct pointer is saved in the match data space, it clobbers the first structure member (->origsrc_addr). Because the _v1 match function grabs this pointer and does not actually look at the v1 origsrc, run time functionality does not break. But iptables -nvL (or iptables-save) cannot know that v1 origsrc_addr has been overloaded in this way: $ iptables -p tcp -A OUTPUT -m conntrack --ctorigsrc 10.0.0.1 -j ACCEPT $ iptables-save -A OUTPUT -p tcp -m conntrack --ctorigsrc 128.173.134.206 -j ACCEPT (128.173... is the address to the v2 match structure). To fix this, we take advantage of the fact that the v1 and v2 structures are identical with exception of the last two structure members (u8 in v1, u16 in v2). We extract them as early as possible and prevent the v2 matching function from looking at those two members directly.

The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).

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.

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.

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.

The existing connection tracking subsystem in netfilter can only handle ipv4. There were basically two choices present to add connection tracking support for ipv6. We could either duplicate all of the ipv4 connection tracking code into an ipv6 counterpart, or (the choice taken by these patches) we could design a generic layer that could handle both ipv4 and ipv6 and thus requiring only one sub-protocol (TCP, UDP, etc.) connection tracking helper module to be written. In fact nf_conntrack is capable of working with any layer 3 protocol. The existing ipv4 specific conntrack code could also not deal with the pecularities of doing connection tracking on ipv6, which is also cured here. For example, these issues include: 1) ICMPv6 handling, which is used for neighbour discovery in ipv6 thus some messages such as these should not participate in connection tracking since effectively they are like ARP messages 2) fragmentation must be handled differently in ipv6, because the simplistic "defrag, connection track and NAT, refrag" (which the existing ipv4 connection tracking does) approach simply isn't feasible in ipv6 3) ipv6 extension header parsing must occur at the correct spots before and after connection tracking decisions, and there were no provisions for this in the existing connection tracking design 4) ipv6 has no need for stateful NAT The ipv4 specific conntrack layer is kept around, until all of the ipv4 specific conntrack helpers are ported over to nf_conntrack and it is feature complete. Once that occurs, the old conntrack stuff will get placed into the feature-removal-schedule and we will fully kill it off 6 months later.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
