* 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
- assume "tcp+udp" if no protcol is specified in rules or redirects (#13422, #13386)
- add support for fwmark matches and mark setting targets
SVN-Revision: 36521
- support network names in per-zone 'masq_src', 'masq_dest' and 'subnet' options (#13197)
- do not allow src_mac option for SNAT rules
SVN-Revision: 36090
* Introduce "option reload" for includes to specify whether includes should be processed on reload (e.g. when tapping into internal chains)
* Allow "network" and "device" commands while firewall is running (to make them usable in includes)
SVN-Revision: 36009
* Adds support for emitting hotplug events when creating and clearing zones (fixes miniupnpd)
* Make NAT reflection direction configurable
* Map init script stop action to flush
* Map init script reload action to reload
* Respect init script disabled state in hotplug handler
SVN-Revision: 35998
* Fixes compilation against eglibc
* Fixes tracking logic when selectively restarting IPv4 or IPv6 firewall
* Fixes tracking logic for user chains by differentiating between reloads and restarts
* Introduces per-zone user chains {input,output,forwarding,prerouting,postrouting}_$zone_rule
* Supports legacy "tcpudp" protocol notation again
SVN-Revision: 35969
- all uci rules are boxed in custom chains now, so a firewall stop leaves user rules intact
- properly handle selective ipv4 or ipv6 only firewall start/stop/restart actions
- support ip ranges (e.g. option src_ip '!192.168.1.1-192.168.1.100' -> -m iprange ! --src-range 192.168.1.1-192.168.1.100')
- support time options (e.g. option weekdays 'Mon Tue Sat' -> -m time --weekdays 1,2,6')
SVN-Revision: 35738
