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
