ruleset: reduce ksoftirqd load by refering to looopback by numeric id

2023-11-03T13:11:06Z

Reduce ksoftirq load by half using more efficient reference to loopback which always has index equal to one. Should help a lot with openwrt/openwrt#12914, openwrt/openwrt#12121 and similar iperf3 cases clamping against 100% CPU usage.

ruleset: dispatch ct states using verdict map

2023-11-03T13:09:43Z

In case the dropping of invalid conntrack states is enabled, using a verdict map allows us to use only one rule instead of two, lowering the initial rule match overhead. Signed-off-by: Andris PE [whitespace cleanup, rebase, extend commit subject and message] Signed-off-by: Jo-Philipp Wich

ruleset: drop ctstate invalid traffic for masq-enabled zones

2022-10-26T13:45:16Z

For NAT enabled zones, stage rules to drop forwarded traffic with conntrack state "invalid" and honor `masq_allow_invalid` option to inhibit those rules. This ports the corresponding firewall3 logic to firewall4. Ref: https://forum.openwrt.org/t/x/140790 Signed-off-by: Jo-Philipp Wich

ruleset: reorder declarations & output tweaks

2022-06-14T14:27:26Z

- Omit "Set definitions" header if no sets are declared - Always emit ${zone}_devices and ${zone}_subnets defines, even if empty - Move CT helper definitions to the top - Move ${zone}_helper chain definitions after ${zone}_forward chain defs - Consistently use two line spacing for output sections Signed-off-by: Jo-Philipp Wich

ruleset: fix conntrack helpers

2022-06-14T14:26:07Z

In nftables, helper assignments need to be performed after the conntrack lookup has completed. Using the raw priority results in the assignment being done before the conntrack lookup, which breaks conntrack helpers. Fix this by moving the jumps helper rule chains to a new toplevel `prerouting` and the existing `output` chain respectively.

ruleset: correct mangle_output chain type

2022-05-30T18:59:27Z

Use the `route` chain type for the `mangle_output` chain since rules in this chain influence egress packet routing. Fixes: #9955 Signed-off-by: Jo-Philipp Wich

ruleset: fix chain selection for mark and dscp targets

2022-01-22T19:36:29Z

Align the chain selection logic for mark and dscp targets with the one implemented in firewall3 with commit https://git.openwrt.org/61db17e Also add corresponding testcases to assert the correct selection logic. Signed-off-by: Jo-Philipp Wich

fw4.uc: handle zone masq6 option

2022-01-22T19:22:17Z

The ruleset template and internal adress selection logc has been prepared for IPv6 masquerading already but the toplevel option was not exposed until now. Also add some initial testcases for zone configuration while we're at it. Signed-off-by: Jo-Philipp Wich
