unkin-agent	0b92f1c2f3	Refuse mutating commands during a try and scope reverts to the try ID ... apply, flush and purge take the try lock and fail with ErrPending, which now names 'tomswall revert' as the recovery after a failed automatic revert. Each try gets an ID passed to the timer's 'revert --id', so a stale timer cannot revert a newer try. Adds tests for Revert success/failure/stale ID and for restoring a present table at the engine level.	2026-10-03 20:56:52 +10:00

benvin	8ae09c0941	Agent: translate blrules/conntrack/secmarks/vars ... Map the rendered global-compiled tail into native config.Blrules/Conntrack/ Secmarks/Vars.	2026-07-26 16:07:28 +10:00
benvin	6d16035a0b	Agent: translate traffic-control long-tail (mangle/accounting/tc_*) ... Map the rendered mangle/accounting/tc_* sections into native tomswall config.	2026-07-26 15:57:05 +10:00
benvin	b94cb96510	Agent: translate per-device L2/misc long-tail ... Map the rendered tunnels/stopped_rules/proxy_arp/proxy_ndp/arp_rules/maclist sections into native tomswall config.	2026-07-26 15:19:09 +10:00
benvin	59e8320dda	Agent: translate per-device routing long-tail (hosts/providers/routes/routing_rules) ... Map the rendered hosts/providers/routes/routing_rules sections into native tomswall config (config.Host/Provider/StaticRoute/RoutingRule). The route's egress interface (oif) maps to StaticRoute.Device.	2026-07-26 13:02:17 +10:00
benvin	06928bc150	Agent: translate the NAT tier into native config ... The agent now maps the rendered NAT sections into native tomswall config: - snat/masquerade -> config.SNAT, expanding a rendered rule's egress interface list and source CIDRs into one native rule per (egress, source) pair (a native SNAT rule takes a single dest interface); carries address/probability. - netmap -> config.Netmap (from_net/to_net -> net1/net2 on the resolved interface). - 1:1 nat -> config.StaticNAT. Unit-tested end to end from RenderedConfig to config.Config.	2026-07-21 22:21:24 +10:00
benvin	66265764df	Agent: report the FIB for reachability scoping ... The agent now collects the device's reachable prefixes from the kernel FIB (including FRR-installed routes) via 'ip route show' / 'ip -6 route show' and reports them to the control plane (POST /devices/{name}/routes) alongside its status. tomswallapi uses these to scope which routers enforce a rule. Route parsing (default routes, ECMP nexthop lines, route-type keywords, host routes, v4/v6) is unit-tested; collection degrades to nil without iproute2.	2026-07-20 22:37:24 +10:00
benvin	e0f54ef320	Add tomswall agent (control-plane pull mode) ... Add `tomswall agent`: it pulls this device's compiled config from tomswallapi, differentially applies it, and reports the applied generation. It caches the last known-good config and, when the control plane is unreachable, keeps applying that cache — it never fails closed. - internal/agent: rendered-config types, HTTP client (fetch + status report), on-disk cache, on-device DNS resolver for dns sets (honors the device's configured resolver, fail-safe on lookup failure), and the pull-apply-report loop behind a mockable Applier. - Translate the interface-agnostic, address-matched rendered model into native tomswall config using the "all:<cidr>" any-interface source/dest form, reusing the existing differential engine. Named-set members are inlined as concrete addresses (native nft set references are a tracked follow-up). - cmd/tomswall: wire the `agent` subcommand (flags + TOMSWALL_* env, --once). - Unit tests: translation, cache, and the don't-fail-closed fallback loop. - Add DESIGN.md documenting the control-plane architecture.	2026-07-20 20:05:49 +10:00
unkinben	8d9a76c751	Add comprehensive nftables compiler with shorewall feature parity ... Rewrites the compiler from ~440 to ~1700 lines covering all major shorewall firewall features: loopback, conntrack fast-path, anti-spoof, DHCP, intra-zone, blacklist/whitelist, conntrack notrack, tunnels (13 types), rules with sections, DNAT/redirect, SNAT/masquerade, static NAT, policies with zone exclusions, MSS clamping, rate limiting, connection limiting, negated addresses, ICMP type matching, TCP RST reject, user/UID matching, mark match/set, NFQUEUE, NONAT, and policy-level rate/conn limiting. Adds full config types for all shorewall subsystems (mangle, accounting, maclist, netmap, providers, tunnels, conntrack, blrules, proxyarp/ndp, routes, tc, secmarks), shorewall migration tooling, expanded CLI commands, expression-level diff engine, and 49 unit tests.	2026-07-01 23:56:44 +10:00
unkinben	2a3eb3b04d	Initial scaffold for tomswall ... Spiritual successor to shorewall — manages nftables directly via google/nftables. Reads a single YAML config covering zones, interfaces, hosts, policy, rules, snat, and named portgroups. Computes differential changes against the running nftables state and applies them atomically. Supports detecting and purging rules added outside of tomswall.	2026-06-28 23:43:16 +10:00
