Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.

Utilize the new selective conntrack flushing facility to clear
out active conntrack entries referring to old IP addresses after
a firewall reload.

Properly parse and pass arbritary netmasks to iptables, this allows
specifying ranges like '::c23f:eff:fe7a:a094/::ffff:ffff:ffff:ffff' to
match the host part of an IPv6 address regardless of the currently active
IPv6 prefix.

The commit 92281eb747b56e748b7c3d754055919c23befdd4 broke fw3_ubus_addresses() so that
no addresses where returned at all, this caused fw3 to not emit NAT reflection rules
anymore.

- Do not consider bitmap storage for IPv6 family sets
- Move ipset family parameter before any additional option
- Only emit family parameter for hash sets
- Do not allow IPv6 iprange for IPv4 sets and vice versa

The firewall3 implementation as well as the shell implementation predating it
used to process the tcp_ecnoption as boolean while it actually is an integer.
Change the code to parse tcp_ecn as integer.

- instead of writing one (or more) ACCEPT rules in the filter table
for each redirect install a global ctstate DNAT accept rule per zone
- discard rules and redirects which have invalid options set instead
of silently skipping the invalid values
SVN-Revision: 38849
* Use network.interface dump call instead of individual status calls
to reduce overall netifd lookups and invokes to 1 per fw3 process.
* Allow protocol handlers to assign a firewall zone for an interface
in the data section to allow for dynamic firewall zone assignment.
SVN-Revision: 38504
- do not insert duplicate rules when setting up reflection to a zone containing multiple interfaces
- set up reflection for any protocol, not just TCP and UDP
SVN-Revision: 38361
- optimizes chain usage for ingress rules
- adds limit match support for redirect rules
- fixes automatic redirect dest detection on little endian systems
- leaves base chains in place on reload to allow user rules to target e.g. "reject"
SVN-Revision: 36871
- simplifies using ipsets for rules and redirects, match direction can be specified in-place like option ipset 'setname src dst dst'
- uses zone_name_src_ACTION chains for input rules, this fixes logging with log enabled src zones
SVN-Revision: 36854
- allows building without IPv6 support
- uses more robust rules to cope with missing libext.a
- uses better linking strategy to avoid symbol clashes with older iptables
- introduces source compatiblity layer for different libxtables versions
SVN-Revision: 36736
- allows symbolic notation for src_ip, src_dip and dest_ip options, e.g. option src_ip 'lan' to automatically resolve to "192.168.1.0/24"
- automatically infer destination zone for redirects from target ip, this makes 'dest' optional and nat reflection setup more robust
- properly support output rules with dest '*' to hook directly into delegate_output
- fixes crash when processing rules with unresolved targets
SVN-Revision: 36721
- Use weak references for instantiating libext*.a matches, makes fw3 independant from the compile time features of iptables
- Do not leak memory when processing rules with unknown targets or matches
SVN-Revision: 36698
- fixes reload when firewall is not running already
- fixes crash when ipsets are supported but undeclared
- fixes handling of per zone user chains on reload
SVN-Revision: 36689
* use libiptc and libxtables directly to manage ruleset, iptables-restore is unreliable and prone to race conditions
* make ipset integration more reliable
SVN-Revision: 36681
