[NETFILTER]: Restore {ipt,ip6t,ebt}_LOG compatibility

2006-02-27T21:04:17+00:00

The nfnetlink_log infrastructure changes broke compatiblity of the LOG
targets. They currently use whatever log backend was registered first,
which means that if ipt_ULOG was loaded first, no messages will be printed
to the ring buffer anymore.

Restore compatiblity by using the old log functions by default and only use
the nf_log backend if the user explicitly said so.

[NETFILTER]: Prepare {ipt,ip6t}_policy match for x_tables unification

2006-02-05T07:51:28+00:00

The IPv4 and IPv6 version of the policy match are identical besides address
comparison and the data structure used for userspace communication. Unify
the data structures to break compatiblity now (before it is released), so
we can port it to x_tables in 2.6.17.

[NETFILTER] ip6tables: remove unused definitions

2006-01-17T10:39:19+00:00

These definitions ware used for only internal use in kernel <= 2.6.13,
which had not introduced the unified parser of IPv6 extension header yet.

[NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tables

2006-01-12T22:06:43+00:00

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.

[NETFILTER]: make ipv6_find_hdr() find transport protocol header

2006-01-05T20:21:16+00:00

The original ipv6_find_hdr() finds the specified header in IPv6 packets.
This makes it possible to get transport header so that we can kill similar
loop in ip6_match_packet().

[NETFILTER]: Add "revision" support to arp_tables and ip6_tables

2005-10-31T18:36:08+00:00

Like ip_tables already has it for some time, this adds support for
having multiple revisions for each match/target.  We steal one byte from
the name in order to accomodate a 8 bit version number.

[NETFILTER] ip6tables: remove duplicate code

2005-09-19T22:34:40+00:00

Some IPv6 matches have very similar loops to find IPv6 extension header
and we can unify them. This patch introduces ipv6_find_hdr() to do it.
I just checked that it can find the target headers in the packet which has
dst,hbh,rt,frag,ah,esp headers.

[NETFILTER6]: Add new ip6tables HOPLIMIT target
