Josh Siviour 75fb15be2b feat: spx admin init/join listen-vs-advertise split + br-mgmt OVS provisioning (#158)
* fix: provision br-mgmt as OVS bridge + loopback guard for LB gateway

Convert br-mgmt from an externally-provisioned Linux bridge to an OVS
bridge owned by scripts/setup-ovn.sh, giving every deployment type
(tofu-cluster, production single-node, production multi-node) a single
provisioning path.

setup-ovn.sh grows --mgmt-bridge / --mgmt-cidr / --mgmt-iface /
--no-mgmt-bridge flags. Default creates br-mgmt with fail-mode=standalone
(excluded from ovn-bridge-mappings so ovn-controller ignores it) and
assigns the mgmt IP via a systemd-networkd drop-in so it survives reboot.

SetupMgmtTapDevice / CleanupMgmtTapDevice switch from `ip link master`
to `ovs-vsctl add-port` / `del-port` to match the new bridge type.

Add a loopback guard to wireLBAgentConfig's fallback branch: on a
production single-node with awsgw bound to 127.0.0.1 and no mgmt bridge,
the fallback previously injected 127.0.0.1 into LB VM cloud-init —
silently unreachable because the VM's loopback is its own. The guard
leaves GatewayURL empty and the existing "LB agent gateway URL not
configured" error fires instead. Regression covered in
daemon_wire_lb_test.go.

* fix: auto-detect primary IP for admin init --bind default

Bare `spx admin init` used a 127.0.0.1 default that kept awsgw on loopback
only, so system VMs on br-mgmt could never reach it. Auto-detect the
default-route source IPv4 instead, which keeps TLS cert SANs specific
(still not a wildcard). Dev-install scripts now pass --bind 127.0.0.1
explicitly to preserve loopback-only behavior on laptops.

Closes mulga-siv-7.

* test: refresh wire lb loopback-bind comment for siv-7

* fix: dev-install scripts should let admin init auto-detect --bind

Pinning --bind to 127.0.0.1 on dev installs left awsgw loopback-only while
setup-ovn.sh still provisions br-mgmt, so LB VMs hit 10.15.8.1:9999 with
no listener. Drop the explicit --bind so auto-detect picks the primary IP
and the siv-6 mgmtRouteVia path routes LB traffic to a real listener.

* fix: bind awsgw and predastore on 0.0.0.0 in spinifex.toml template

PR #144 (nats TLS) made every service listen on --bind's specific IP. For
awsgw and predastore this broke localhost-reachability that the UI proxy
(spinifexui/spinifexui.go:193-194) and AWS CLI spinifex profile rely on —
latent since #144, surfaced by siv-7's auto-detect default on dev installs
(502 from the UI).

Hardcode awsgw and predastore host fields to 0.0.0.0 so both listen
wildcard; loopback clients (UI proxy, spinifex AWS CLI profile, same-host
daemon → predastore) keep working, LAN clients still reach them via the
LAN-IP SAN on the cert. daemon.host and nats.host stay as {{.BindIP}}
because peer-advertised values must not resolve to 0.0.0.0/loopback.
predastore.host normalization at config.go:207 rewrites 0.0.0.0 → 127.0.0.1
for local-node consumers, so existing callers see a usable connect address.

* revert: siv-7 --bind auto-detect + siv-6 loopback guard (prep mulga-siv-8)

Clears the deck before layering the listen-vs-advertise split
(mulga-siv-8). The plan restores --bind=0.0.0.0 as the single-node
default and introduces an explicit --advertise flag for off-host dial
targets; the reverted approach (auto-detect a specific IP at init,
hardcode 0.0.0.0 in the template, guard against loopback in
wireLBAgentConfig) becomes redundant once that lands.

Reverts:
- bb0ad3a fix: bind awsgw and predastore on 0.0.0.0 in spinifex.toml template
- f20a47b fix: dev-install scripts should let admin init auto-detect --bind
- 49b0b4e test: refresh wire lb loopback-bind comment for siv-7
- b88dfdf fix: auto-detect primary IP for admin init --bind default

Also drops the loopback guard from siv-6 (74b6e2d) wireLBAgentConfig
fallback and its regression test — subsumed by the GatewayURL
precedence rework in mulga-siv-8.5 (br-mgmt → AdvertiseIP → error,
no silent empty-string fallthrough). The br-mgmt OVS provisioning
from 74b6e2d is retained.

* feat: admin.DialTarget + AdvertiseHost helpers (mulga-siv-8.2)

Introduce the two small address-resolution helpers the listen-vs-
advertise split needs, with full unit coverage. No callers yet —
dial-site migration lands in mulga-siv-8.5.

- DialTarget(listenAddr): rewrites wildcard listen addresses
  (0.0.0.0:N, [::]:N, :N) to their loopback equivalents so in-process
  clients dial a target the daemon's cert already has in its SANs.
  Specific IPs, loopback, hostnames, and malformed input pass through.
- AdvertiseHost(listenAddr, advertiseIP): picks the host off-host
  clients should dial. Wildcard listen → advertiseIP; specific host →
  that host. Port is dropped so callers append the protocol-appropriate
  port.

Plan: docs/development/bugs/spx-admin-init-bind.md §Proposed Changes/1

* feat: plumb AdvertiseIP through config/formation (mulga-siv-8.3)

Pure data-model change. Add AdvertiseIP to:
- admin.ConfigSettings (local node, populated by init).
- config.Config (per-node; mapstructure "advertise").
- formation.NodeInfo (json "advertise_ip,omitempty") so the join handshake
  carries it between peers.

buildRemoteNodes now prefers n.AdvertiseIP and falls back to n.BindIP so
joined nodes from older clusters / pre-siv-8 joiners keep working.

No behaviour change yet — templates, CLI flag, and dial-site migration
land in siv-8.4 and siv-8.5.

* feat: --advertise flag + resolveAdvertiseIP + templates (mulga-siv-8.4)

Introduce the listen-vs-advertise split at the CLI boundary.

admin init/join:
- --bind default for init is 0.0.0.0 (was 127.0.0.1 under siv-7 revert).
- New --advertise <IP> flag on both init and join; optional, auto-detected
  from DetectNetwork().WAN.IP when --bind is wildcard or loopback.
- resolveAdvertiseIP(bindIP, advertiseFlag, detected) implements
  precedence: flag > specific bindIP > WAN auto-detect > 127.0.0.1 +
  warning.
- Join resolves advertise before building the JoinRequest so peers record
  a reachable dial target (not 0.0.0.0).
- isMultiNode: trigger on --nodes >= 2 regardless of bind literal; operator
  can now run "init --nodes 3" without typing a specific --bind.
- Init success message prints bind / advertise / loopback three-way split.

Templates:
- spinifex.toml: [nodes.X] gains advertise = "{{.AdvertiseIP}}" rendered
  only when AdvertiseIP is set.
- predastore-multinode.toml: iam.nats_url host wrapped in the same
  {{if eq .BindIP "0.0.0.0"}}localhost{{...}}{{end}} shim that
  predastore.toml already uses, so co-resident predastore dials its local
  NATS via loopback instead of 0.0.0.0.

Tests cover the resolveAdvertiseIP matrix, the template advertise field
(present + omitted), and the predastore nats_url loopback shim.

Dial-site migration and GatewayURL rework land in siv-8.5.

* feat: dial-site migration + GatewayURL AdvertiseIP fallback (mulga-siv-8.5)

Switch every in-process dial site to admin.DialTarget so the wildcard
listen address (0.0.0.0) is rewritten to loopback before Dial(): daemon
→ NATS and → predastore (boot, reconnect, status probe, S3 store, service
manifest write), awsgw → NATS. The TLS cert already SANs 127.0.0.1, so
loopback-dial a wildcard-listen service is always valid; the old
0.0.0.0 literal was tripping TLS SAN verification.

Rework wireLBAgentConfig GatewayURL precedence (spinifex/daemon/daemon.go):

  1. AWSGW on specific WAN IP + br-mgmt present → WAN IP (unchanged)
  2. br-mgmt present, AWSGW on 0.0.0.0     → br-mgmt IP (unchanged)
  3. d.config.AdvertiseIP (single-node default install) → AdvertiseIP (NEW)
  4. DevNetworking shim                    → 10.0.2.2 (unchanged)
  5. AWSGW on specific IP, no bridge       → that IP (unchanged)
  6. Else                                  → log error, skip assignment

Kills the pre-siv-8 silent empty-URL failure mode that made
CreateLoadBalancer fail with 'missing system credentials: gatewayURL='
on every fresh single-node install. Supersedes siv-6's loopback guard.

Extend SetupAWSCredentials with a wanIP parameter (reserved for a
future --operator-endpoint flag) and thread AdvertiseIP through
finalizeNodeSetup's three call sites (single-node init, multi-node
init, join). Print 'Bind / Advertise / Loopback' on multi-node init
and join completion to match the single-node summary.
