ovs-monitor-ipsec uses chassis-id as the IKEv2 `@<name>` peer identity in
the strongSwan config it generates. Our per-node IPsec peer cert
(admin.GenerateIPSecPeerCert) carries the node name as CN + dnsName SAN.
With chassis-id left at the package-generated UUID, charon validates
`@<UUID>` against a cert with dnsName=<hostname> — mismatch returns
AUTHENTICATION_FAILED and no xfrm SAs are negotiated.
Pin system-id to hostname (which equals the node name on Mulga clusters)
by writing both the on-disk source of truth (/etc/openvswitch/system-id.conf,
read by ovs-ctl on boot) and the running OVS DB value. Writing only one
would drift on the next reboot — the original "do not override" comment
was right about that hazard, just wrong about the resolution.
Cross-link the invariant in admin/ipsec.go: changing the cert identity
without updating setup-ovn.sh (or vice versa) breaks IKE silently.

The strongswan-charon profile only allows reads from /etc/ipsec.*,
/etc/strongswan.*, and a small fixed allowlist. ovs-monitor-ipsec writes
the per-tunnel strongSwan config with absolute paths to our peer cert +
key under /etc/spinifex/ipsec/, so charon hits 'Permission denied'
loading them (it runs as uid 0 but AppArmor still blocks) and no xfrm
SAs come up. Drop a read grant for /etc/spinifex/ipsec/** into the
profile's local override hook + reload.
Setting Open_vSwitch.other_config:ipsec_encapsulation=true on each
chassis is necessary but not sufficient for OVN native IPsec — without
NB_Global.ipsec=true, ovn-controller never adds options:remote_name to
the Geneve tunnel ports, so ovs-monitor-ipsec sees no IPsec-enabled
tunnels and the kernel xfrm tables stay empty. After enabling
ipsec_encapsulation locally, also write NB_Global.ipsec=true when the
local ovnnb_db socket is present (management node only); workers skip
silently — one writer is enough for a cluster-wide flag.
Adds a scoped sudoers entry pinning the daemon to that exact ovn-nbctl
invocation so the grant can't be reused for other NB mutations.
Pass an optional regex through to each suite's '\''go test -test.run'\'' so
dispatches can target a single test (e.g. '\''^TestMultinodeIPSec$'\'') without
running the full multinode suite. Threaded through single, multinode, and
reboot suite invocations; empty input preserves current behaviour.

The strongswan metapackage's '\''charon-systemd | strongswan-charon'\''
alternative resolves to charon-systemd by default, which ships
/usr/sbin/charon-systemd but not the legacy /usr/sbin/ipsec helper or
/usr/lib/ipsec/charon binary that ovs-monitor-ipsec --ike-daemon=strongswan
shells out to. Install strongswan-charon explicitly to pull
strongswan-starter (legacy ipsec controller) + the matching charon binary,
matching what openvswitch-ipsec.service expects.
Also reset-failed + restart openvswitch-ipsec.service after enable to
recover from the deb post-install starting the service before its
dependencies finished unpacking.
Add static-analysis + behavioural tests that bind every safety and
liveness clause in ADR-0006 (S1-S9, L1-L3) to a named Go test. Failure
output quotes the ADR clause verbatim and points at the offending
file:line so future debugging sessions can't quietly bypass a layer
contract to make a test green.
Static-analysis suite (spinifex/network/invariants/):
- S1 layers_test.go: parses `go list -json`; rejects upward layer
imports and layers pulling from cross-cutter packages
- S2 host_containment_test.go: AST-detects ovs-vsctl / ovn-nbctl /
ovs-ofctl shell-out outside network/host/
- S3 nat_mode_test.go: rejects .UplinkMode() / NATModeFromUplinkMode()
calls outside the init-time resolver locations
- S4 names_test.go: AST-detects OVN object name construction (concat,
fmt.Sprintf, strings.Join) outside topology/names.go
- S5 policy_no_create_test.go: rejects CreateLogical{Switch,Router,...}
and DeleteLogical{...} calls inside network/policy/
- S6 federation_isolation_test.go: rejects TransitSwitch /
TransitRouterPort references and ovn-ic literals outside
network/federation/ (pre-protects the layer before it lands)
- S8 ipsec_test.go: rejects strongswan / xfrm / IKEv2 / libreswan /
openswan imports anywhere in network/
- S9 reconciler_singleton_test.go: rejects Reconcile…Loop and
Reconcile…Pass<n> function names anywhere in network/
- S7 nats_subjects_test.go: scans for `vpc.<verb>` subjects missing
the {azID} segment; calls t.Skip with the gap report so every test
run prints the work-to-do without breaking CI. Flip to t.Fatalf
when the cluster-wide subject rename ships.
Behavioural suite (spinifex/network/reconcile/liveness_test.go):
- L1 reconciler converges: scaled-intent (N=1,3,8) double-Reconcile
property test; asserts second pass is a no-op
- L2 drift bound: structural check that DriftInterval is positive and
≤30 min support window; full fake-clock behavioural test deferred
- L3 federation re-enables: t.Skip stub pointing at the missing
network/federation/ package
Fixes the one production S4 violation the new walker found:
network/external/igw.go was constructing "gw-port-"+vpcID inline.
Adds topology.GatewaySwitchPort(vpcID) helper and retargets both
AttachIGW and DetachIGW callsites through L2.

ovs-monitor-ipsec.service fails to start without an IKE daemon. The
openvswitch-ipsec package only Recommends strongswan, so any apt
config that drops Recommends (or a base image with the recommends
already skipped) leaves the service in a Restart loop with 'IKE
daemon is not installed'. Hoist both packages into setup-ovn.sh so
provisioning is the single source of truth — the bootstrap shim in
mulga is no longer needed.
Phase 4 Slice D (mulga-siv-125.6). Final cleanup of the network-redesign
package layout. services/vpcd/ disappears entirely; the launcher remains
an in-process Service impl, just rehomed under spinifex/vpcd/ (no separate
binary — spx vpcd start stays the cobra entrypoint).
- Delete services/vpcd/mock_ovn.go + ovn.go (compat aliases now dead post
Slice C; only callsite was launchService's NewLiveOVNClient, inlined to
ovn.NewLiveClient).
- git-rename services/vpcd/vpcd.go + vpcd_test.go to spinifex/vpcd/.
- Retarget three importers (spinifex/service/service.go +
service_test.go, cmd/spinifex/cmd/service.go) to the new path.
- Fix stale services/vpcd / TopologyHandler comments in network/reconcile/
+ network/external/types.go + spinifex/vpcd/vpcd.go.
- service-interfaces.yaml vpcd path updated.
- Plan doc §13/§14/§16 + §9.2/§19 updated: drop cmd/vpcd/main.go (was
speculative; never built) in favour of in-process Service impl at
spinifex/vpcd/vpcd.go. Plan §16 Created list now lists subscribers/.
Phase 4 plan items 1+2 (remove services/vpcd, entrypoint location)
satisfied. Items 3+4 remain blocked on mulga-siv-125.4 + 125.5 (bundled
join token, plan archive).
Phase 4 Slice C (mulga-siv-125.6). Promotes the NATS event handlers out of
services/vpcd into a new spinifex/network/subscribers package. Subscriber
holds the topology/policy/external managers directly — the lazy *Once
adapter shim (topology_manager.go) is deleted along with vpcd's local
event-struct copies.
launchService now constructs topology.LiveManager eagerly with a DNS
callback derived from external pools (preserving the unscoped-pool lookup
old TopologyHandler.lmDNSServer did), builds every manager up front, then
hands them to subscribers.New + Subscribe. reconcile.New receives
topology.Manager directly instead of through the adapter.
Bridge-mode constants and waitForFlowsHV move into vpcd.go alongside the
launcher; they were left behind as topology.go's last responsibilities.
Handler-layer tests (topology_test.go, security_test.go, integration_test.go)
are dropped: substance is covered by network/topology, network/policy,
network/external manager tests. subscribers/subscribers_test.go adds
focused coverage: missing-dep rejection, topic registration smoke, and
bad-JSON envelope per topic.
services/vpcd is now down to the launcher + the ovn/mock compat aliases
(removed in Slice D when the launcher promotes to cmd/vpcd/).
Phase 4 / mulga-siv-125.6 Slice B.
Production path no longer touches any of:
- RetrofitAllGatewayPortNetworks / RetrofitAllExternalLocalnetOptions —
the 5-pass startup leftovers that network/reconcile (Phase 2.2) made
redundant. Nothing called them outside tests.
- reconcileIGW + its allocateGatewayLRPIP / gwLrpRange helpers + the
ipv4ToUint32 / uint32ToIPv4 utilities — superseded by
external.IGWManager (Phase 2.4) which carries its own pool logic.
- ensureLocalnetOptions / ensureGatewayPortNetworks /
expectedGatewayPortNetwork — read-before-write retrofit shims for the
same code paths.
- generateMAC — only callers were reconcileIGW + its tests.
useCentralizedNAT (the bridge-mode bleed flagged in plan §2.2) is
replaced by a policy.NATMode value injected via WithNATMode(...). The
mode is resolved once in vpcd.go from host.UplinkMode and threaded into
both the topology-handler lazy managers and the reconciler stack, so
"is this veth?" is no longer a question topology.go can ask. The
TopologyHandler defaults to NATModeDistributed when WithNATMode is
omitted, matching the previous default.
Drops services/vpcd/topology.go from 1220 LOC to 693, deletes ~700 LOC
of obsolete tests (TestGenerateMAC, TestEnsureLocalnetOptions_*,
TestRetrofitAllExternalLocalnetOptions_FixesClearedOptions,
TestReconcileIGW_*, TestGwLrpRange), and frees the nbdb + utils +
net imports in topology.go.
Stale "phase 4 migrates those onto the new managers" comment in vpcd.go
fixed in passing — the subscribers were migrated in Phase 2.6
(mulga-siv-129); only the file-relocation parts of Phase 4 remain.
Stale ensureLocalnetOptions / ensureGatewayPortNetworks references in
network/ovn/{live.go,mock/mock.go} doc comments also cleaned up.
Phase 4 / mulga-siv-125.6 Slice A. Pure import rename, no logic change.
The OVN Northbound DB model (LogicalSwitch, LogicalRouter, DHCPOptions,
etc.) lived under services/vpcd/nbdb/ because that was the original home
of every OVN caller. After Phase 1+2 the L1 client (network/ovn) and all
L3/L5 managers (network/policy, network/external, network/topology,
network/reconcile) became the primary callers — 8 importers in network/*
vs 2 in services/vpcd/. The directory move puts the schema model where
its consumers are, and unblocks deleting services/vpcd/ entirely once
the subscriber/launcher relocations land (Slices B–D).
Two pre-existing failures blocked preflight on the branch:
- govulncheck flagged golang.org/x/net@v0.54.0 (GO-2026-5026, ASCII Punycode
rejection bug in idna.ToASCII); reached via utils.DownloadFileWithProgress.
Bump to v0.55.0; go mod tidy carries x/sys to v0.45.0.
- TestTopologyHandler_SubnetCreate_RouterPortFails asserted subnet create
fails when the parent VPC router is missing. That contract changed in
aed7b2e (mulga-siv-133), which made handleSubnetCreate call EnsureVPC
idempotently before EnsureSubnet to avoid a NATS publish-order race.
Delete the now-impossible failure case.
Provisioning now runs `systemctl enable --now openvswitch-ipsec.service`
alongside openvswitch-switch and ovn-controller. The spinifex-daemon
process drops its `enable --now` shell-out and only polls is-active.
Sudoers gains one read-only line:
spinifex-daemon ALL=(root) NOPASSWD: /usr/bin/systemctl is-active openvswitch-ipsec.service
This mirrors the existing vpcd ovn-controller is-active precedent and
removes the daemon's need for systemd-write capability. Aligns with
least-privilege service account pattern: provision enables services,
daemon only reads status.
If the unit is inactive at runtime, the daemon refuses to flip
ipsec_encapsulation=true (silent-drop guard from mulga-siv-136) and
surfaces a clear error pointing at scripts/setup-ovn.sh.
Multi-tenant default VPCs share the same subnet CIDR (172.31.0.0/20) per
account. The existing FindDHCPOptionsByCIDR gate at apply.go:107 found
the first account's DHCP_Options row and skipped creation for every
subsequent subnet with the same CIDR. Those subnets' ports then attached
nothing (FindDHCPOptionsByExternalID misses on subnet_id), VMs got no
DHCPv4 lease, and SSH/ICMP into them silently failed even though SG
ACLs and NAT were correct.
Switch the gate to FindDHCPOptionsByExternalID keyed on spinifex:subnet_id
so each subnet owns its own row, matching the attach lookup at line 203.
Verified: account 000000000001 default VPC RunInstances now produces an
LSP with dhcpv4_options populated, VM cloud-init reports a 172.31.0.5/20
lease + default route via 172.31.0.1, and ping + ssh TCP handshake to
the EIP succeed end-to-end. Stale DHCP_Options row for the prior dead
subnet was wiped manually; reconciler recreated the correct row for the
live subnet on its next pass.
admin init leaves the default SG closed (AWS parity); the Go single suite
never ported the Phase-5 SG-ingress block that run-e2e.sh has had since day
one, so every test runner SSH/ping probe hits the OVN port-group ACL drop.
- ec2helpers: add AuthorizeICMPIngress + EnsureDefaultSGOpen helpers.
- single/main_test: open default SG once per process in pkgFixOnce.Do.
- witness: extend ensureDefaultSGSSHIngress to authorize ICMP too.
- run-e2e.sh: append matching ICMP authorize next to tcp/22 block.
mulga-siv-134
CI artifact shows `Unit ovs-monitor-ipsec.service could not be found`
on every node. Debian's openvswitch-ipsec package ships the unit as
openvswitch-ipsec.service (the binary inside is ovs-monitor-ipsec, but
systemd's name follows the package). The previous commit guarded on
the wrong unit name, so:
- spinifex-daemon.service Wants=/After= silently no-op'd (missing unit)
- enableOVNIPSec's `systemctl enable --now ovs-monitor-ipsec.service`
failed, daemon logged a warning and continued without flipping
ipsec_encapsulation=true
- TestMultinodeIPSec skipped with `node1 reports ""` because OVS DB
never received the cert pointers
Rename across all 5 spots (daemon, systemd unit, test, CI diag script,
workflow journal capture) to match the Debian package layout.
Note: the package itself still must be present on the CI VM image —
that's tracked in the mulga repo (image-builder provision.sh +
bootstrap-install.sh shim).

When TestSSHProbe times out (3 min, typically because of mulga-siv-134
datapath bug), four downstream tests each re-probe SSH on the same
broken datapath and time out identically — single-node job runs ~24 min
instead of ~12 min, with the same error logged five times.
First waitForSSHReady timeout now sets a package-level atomic flag;
subsequent waitForSSHReady / trySSHReady / requireSSHHealthy calls skip
immediately. Preserves the original red signal on TestSSHProbe and on
any test that genuinely needed SSH (Skip ≠ Pass). Bool variant
(trySSHReady) consults but does not set the flag — its caller already
treats False as advisory warning, not fatal.
TestSGToSGDatapath has its own EventuallyErr SSH wait (not via
waitForSSHReady) and needs an explicit requireSSHHealthy(t) gate at
the top of runSGToSGDatapath. TestNATGateway already calls
waitForSSHReady first so the gate fires naturally.
Refs: mulga-siv-137
enableOVNIPSec set OVS cert pointers + ipsec_encapsulation=true without
ensuring ovs-monitor-ipsec.service was running. Without that daemon, OVS
holds the cert pointers unused, strongSwan never gets IKE config, and
tunnel traffic ovn-controller marks for encryption gets silently
dropped. TestMultinodeIPSec fails on `node1 xfrm has no AEAD SAs`.
- systemd: spinifex-daemon Wants=/After= ovs-monitor-ipsec.service
- daemon: ensureOVSMonitorIPSecActive — systemctl enable --now +
is-active poll; refuses to flip ipsec_encapsulation if daemon is dead
- daemon: single-node short-circuit — no peers means no tunnels means
the flag is at best inert and at worst load-bearing-silent-drop
- ci: capture-net-diag.sh + workflow steps to snapshot OVS/OVN/xfrm
state on failure, fan out across all 3 multinode nodes
Refs: mulga-siv-136
spx admin init now rejects --external-mode=nat and demands --external-pool
when mode=pool. The ansible init role silently skipped pool flags when the
range was unset, so installs fell over inside the spx validator. Make
targets also swallowed `-e` (make's env-override flag), so operators could
not override pool start/end without editing defaults.yml.
- vars/defaults.yml: rename nat_gateway_ip → external_gateway_ip; add
spinifex_external_no_external opt-out; document the spx flag contract.
- roles/init/tasks/main.yml: drop NAT branch; assert pool range upfront
with a fail_msg pointing at EXTRA_VARS / defaults.yml; emit gateway,
prefix-len, gateway-ip only when explicitly set (let spx auto-detect);
honour --no-external.
- playbooks/dev-reset.yml: rename captured var; coerce legacy
external_mode=nat to pool with a warn; tighten gateway regex with \b.
- Makefile: ansible-dev-* targets now forward EXTRA_VARS="key=val ..."
through --extra-vars so `make` callers can override without editing
defaults.yml.
- scripts/ansible/README.md: document pool requirement, both invocation
styles (direct -e vs make EXTRA_VARS), NAT removal.
vpc.create-vpc and vpc.create-subnet are independent NATS events with
no inter-event ordering guarantee. Tenant bootstrap on iam.account.created
publishes both within <1ms, so the subnet handler's
CreateLogicalRouterPort can race the parent VPC's CreateLogicalRouter and
fail with "logical router not found". The cascade fails CreateNetworkInterface
which fails RunInstances which surfaces as InsufficientInstanceCapacity to
the SDK — masking the underlying topology race.
handleSubnetCreate now calls EnsureVPC(VPCID-only) before EnsureSubnet.
EnsureVPC short-circuits on existing LR (idempotent), so the race-winning
vpc.create-vpc handler's full CIDR/VNI ExternalIDs are preserved; if subnet
wins the race the LR is created with bare ExternalIDs (cosmetic) and the
follow-on vpc.create-vpc short-circuits.
Adds TestIntegration_SubnetBeforeVPC regression covering both orderings.
Closes mulga-siv-133.
Rebase onto dev pulled in daemon_system_instance_test.go which used
the legacy 3-arg NewExternalIPAM(jsNC, js, pools). The feature branch
already narrowed the signature to (js, pools) via the upstream-DHCP
config drop; align the test with the current signature.
applyIGWs previously deferred to the NATS handler when an intent IGW
had no external switch in OVN. When the vpc.igw-attach event is lost
(bootstrap-time default-VPC IGW published before vpcd subscriber is
ready), deferral never resolves and VM public-IP traffic dies.
Call IGWManager.AttachIGW directly — it is idempotent (short-circuits
when the external switch already exists), so the reconciler converges
default-VPC IGWs on first pass without duplicating work on subsequent
passes.
Closes mulga-siv-132.
Reconciler intent loader (network/reconcile/intent.go::loadIGWs) filters
IGW records with `State == "attached"`, but AttachInternetGateway was
writing `State = "available"`. The reconciler therefore never picked up
any attached IGW — `intent_igws=0` on every pass — so the OVN external
switch + gateway LRP + WAN bridge wiring built by IGWManager.AttachIGW
never ran for default-VPC IGWs (whose live `vpc.igw-attach` publish at
daemon bootstrap is lost — vpcd subscriber not yet wired).
Net effect on single-node e2e: every SSH probe to 192.168.x public IPs
timed out (TestSSHProbe, TestModifyInstanceAttribute, TestRebootInstance,
TestNATGateway, TestSGToSGDatapath) because SNAT/DNAT rules on the VPC
router had no path to the external network.
Match AWS InternetGatewayAttachment.State semantics:
- Attach: State="attached"
- Detach: State="detached"
Detach value is internal — recordToEC2 gates Attachments on VpcId != "",
so the detached State is never surfaced to API consumers.
Bead: mulga-siv-131
TestMultinodeIPSec asserts:
- OVS DB on every node carries certificate/private_key/ca_cert pointers
and other_config:ipsec_encapsulation=true (what daemon.enableOVNIPSec
writes).
- ip xfrm state on every node has at least one AEAD SA in AES-GCM mode
(rfc4106(gcm(aes)) or gcm(aes)) within 90s.
- tcpdump catches ESP (ip proto 50) on the underlay (best-effort —
logged only; geneve may be idle during the 5s capture window).
Skips cleanly when the cluster was bootstrapped with --ipsec=false
(no ipsec_encapsulation key on first node).
Read-only over SSH; runs in the parallel bucket alongside the other
non-mutating multinode tests.
When network.ipsec_enabled is true (default), the daemon points the
local OVS DB other_config at the per-node IPsec peer cert that admin
init / admin join provisioned (configDir/ipsec/peer.{pem,key} + the
cluster CA at configDir/ca.pem), then sets
other_config:ipsec_encapsulation=true.
ovs-monitor-ipsec (shipped by the openvswitch-ipsec package) consumes
those pointers and materialises strongSwan configs for every Geneve
tunnel ovn-controller programs — including OVN-IC inter-AZ tunnels
when federation lands in Phase 3a.
Missing cert files log a warning and leave Geneve plaintext; operators
upgrading an older cluster reissue certs via spx admin to close the
gap.
Bead mulga-siv-125.3.5.
openvswitch-ipsec provides ovs-monitor-ipsec, which reads the
Open_vSwitch.other_config cert/key/CA pointers and materialises
strongSwan configs for every Geneve tunnel managed by ovn-controller.
Pulls in strongswan + strongswan-pki as transitive deps.
Required by bead mulga-siv-125.3.5.
Add --ipsec bool flag (default true) on adminInitCmd. Single-node init
and the multi-node leader path both emit an IPsec peer cert after the
existing CA+server-cert generation. The multi-node formation server
propagates the IPSecEnabled flag to joining nodes via NetworkConfig;
admin join honours it and emits its own peer cert during the same
cert-issuance step that already produces the server cert.
spinifex.toml template gains an unconditional [network] block carrying
ipsec_enabled so the value is visible to operators on every install
regardless of whether external networking is configured. The daemon
reads it via cluster config (NetworkConfig.IPSecEnabled).
Bead mulga-siv-125.3.5.
Add GenerateIPSecPeerCert + IPSecCertPaths in spinifex/admin so admin
init (and the future admin add-node path) can issue per-node IKEv2 peer
credentials signed by the existing cluster CA. The cert carries
id-kp-ipsecIKE (RFC 4945) so strongSwan accepts it as an IKEv2 peer
credential when ovs-monitor-ipsec materialises tunnel configs.
Cluster CA is reused directly — no intermediate strongSwan PKI today;
when intermediate CAs land that becomes a separate workstream.
The cert/key pair lives under {configDir}/ipsec/peer.{pem,key}; the
daemon points OVS Open_vSwitch.other_config (certificate, private_key,
ca_cert) at these paths when network.ipsec_enabled is true.
Add IPSecEnabled to NetworkConfig in both the cluster TOML schema and
the formation handshake payload. Default true so AWS-parity intra-AZ
encryption is on by default. Operators can flip false in
[network] for trusted single-rack lab topologies.
Phase 2.5 (bead mulga-siv-125.3.5) consumes the flag from admin init
(strongSwan provisioning), formation server (propagates to joiners),
and daemon startup (ovs-vsctl ipsec_encapsulation toggle).
The dhcp_manager removed in Phase 2.3 (bead mulga-siv-125.3.3) owned the
spinifex-dhcp-leases KV bucket. The migrate framework only handles
per-bucket schema version bumps, not bucket deletion, so the obsolete
bucket would linger on upgraded clusters.
Add a one-shot tombstone after initJetStream that deletes the bucket if
present. DeleteKVBucketIfExists treats ErrBucketNotFound and
ErrStreamNotFound as success, so the call is idempotent across restarts.
Part of bead mulga-siv-125.3.3.
Adds a Purpose enum (handlers/ec2/vpc/purpose.go) tagging every IP
allocation with its semantic role (eni-primary, eni-public, eip,
igw-lrp, natgw-external, …) so multi-VPC clusters can reclaim/audit
by (owner, purpose).
External IPAM (spinifex-external-ipam, v1→v2):
- ExternalIPAllocation.Type → .Purpose; legacy values mapped via
LegacyExternalTypeToPurpose (gateway→igw-lrp, auto_assign→eni-public,
elastic_ip→eip). Unknown legacy values warn and become "unknown".
- AllocateIP / AllocateFromPool / allocateFromPool param rename
allocType→purpose. All call sites pass Purpose* constants.
- migrate/002_external_ipam_purpose.go: idempotent CAS-retry migration
with v1/v2-union record shape so partial migrations resume cleanly.
Internal IPAM (spinifex-vpc-ipam, v1→v2):
- IPAMRecord.Allocated []string → []IPEntry{IP, Purpose, OwnerID}.
- AllocateIP gains purpose+ownerID args; ReleaseIP unchanged (still
keyed on IP).
- AllocatedIPs returns []IPEntry.
- eni.go reorders eniId generation before AllocateIP so the owning
resource ID lands on the new entry.
- migrate/003_ipam_purpose.go: cross-bucket backfill that reads the
ENI bucket via the new RunKVWithJetStream path. Orphaned IPs
(no owning ENI) warn and become Purpose=unknown.
Migrate framework:
- KVContext gains an optional JetStream field; new
Registry.RunKVWithJetStream method threads it through. RunKV
signature unchanged — all other callers are unaffected.
Tests:
- ipam_test.go: AllocateIP signature updates; AllocatedIPs now asserts
IP / Purpose / OwnerID on the returned entries.
- external_ipam_test.go: replaces "auto_assign"/"elastic_ip" literals
with PurposeENIPublic/PurposeEIP and asserts alloc.Purpose.
- migrate/002 + 003 tests: schema-detect, idempotent rerun,
no-JetStream fallback, empty bucket.
Closes mulga-siv-129 slice 4d. Part of bead mulga-siv-125.3.3.
handleIGWAttach now unconditionally delegates to external.IGWManager.
attachIGWLegacy (~207 lines, ~5 OVN write steps + chassis scheduling)
deleted along with its dispatcher branch in handleIGWAttach. The
ExternalPoolConfig.IsDHCP() dead stub is gone.
No code paths or NATS subjects regress: the static-pool / distributed
branches were already going through external.IGWManager since Slice 4d
(6719dc3).
Hard-error in LoadConfig on legacy keys: [network] external_dhcp,
[nodes.<n>.vpcd] dhcp_bind_bridge, and [[network.external_pools]]
source = "dhcp". Add pool range validation (must fit inside the
gateway/prefix_len CIDR; per-cluster non-overlap).
Strip ExternalDHCP from config.NetworkConfig + formation.NetworkConfig
+ admin.ConfigSettings, and DhcpBindBridge from config.VPCDConfig +
admin.ConfigSettings + vpcd.Config. vpcd.ExternalPoolConfig.IsDHCP()
short-circuits to false; the field and downstream DHCP branches in
external_ipam / topology.go remain for Slice C to delete together with
dhcp_manager.
cmd/spinifex/cmd/admin.go: drop useExternalDHCP path and the
detectedDhcpBindBridge helper; require --external-pool when
--external-mode=pool; auto-detect default no longer infers source=dhcp.
service.go's wan_bridge legacy-key rejection now advises removing the
key entirely (vpcd auto-detects br-wan), not renaming to
dhcp_bind_bridge.
Two topology_test cases that exercise the DHCP gateway-LRP path are
skipped — Slice C deletes attachIGWLegacy and these tests together.
handleIGWAttach now branches at decode time:
- Centralised NAT + DHCP-sourced pool keeps using attachIGWLegacy because
the gateway-LRP IP comes from vpc.dhcp.acquire, and that DHCP client is
the vpcd-local manager that bead mulga-siv-125.3.3 will retire.
- All other shapes (distributed NAT, static-range pool, no pool)
delegate to external.IGWManager.AttachIGW. The manager mirrors every
step the legacy handler ran — external switch + localnet port +
gateway LRP + switch-side router peer + default route + chassis HA +
waitForFlowsHV tail barrier — so observable behaviour is unchanged.
handleIGWDetach drops its inline OVN walk entirely; both paths exit
through external.IGWManager.DetachIGW followed by releaseGatewayLRPLease.
The lease release stays in vpcd because the upstream client lives in
services/vpcd/dhcp; calling it after every detach is safe because the
upstream server expires unknown leases on its own.
Lazy-constructed IGWManager added on TopologyHandler (igwmOnce). Pool,
allocator (StaticRangeAllocator), chassis, NAT mode, NAT manager, route
manager, and FlowsBarrier are all derived from the existing
TopologyHandler state.
The DHCP-coupled legacy branch retains its full inline OVN logic; it
will disappear in slice-after-125.3.3 follow-on. Slice 4 of
mulga-siv-129, sub-step d.
handleAddNAT / handleDeleteNAT now decode the NATS event and delegate to
policy.NATManager.{AddEIP,DeleteEIP}. The behavioural contract is
preserved end-to-end:
- Idempotency-skip on a matching dnat_and_snat row (same VPC + LogicalIP,
plus MAC + LogicalPort under distributed NAT) moves into AddEIP so
duplicate vpc.add-nat publishes never tear down the rule the previous
invocation just installed (mulga-siv-124).
- Stale-rule cleanup across every router stays in AddEIP.
- Post-write waitForFlowsHV barrier is now driven by the manager via the
FlowsBarrier option wired in services/vpcd (slice 4a).
- DeleteEIP returns nil on ErrNATNotFound, matching the handler's
fire-and-forget "already absent = success" semantic.
The vpcd "errors" import drops out with the inline error-comparison.
Slice 4 of mulga-siv-129, sub-step c.
handleAddNATGateway / handleDeleteNATGateway now decode the NATS event
and delegate to policy.NATManager.{AddNATGateway,DeleteNATGateway}. The
manager carries identical OVN logic — same snat type, same ExternalIDs
(spinifex:vpc_id + spinifex:nat_gateway_id) — so existing
TestTopologyHandler_AddNATGateway / DeleteNATGateway suites stay green.
Lazy-constructed NATManager added on TopologyHandler (natmOnce). Mode is
derived from the bridge mode (veth → centralized, direct → distributed)
and the FlowsBarrier is bound to waitForFlowsHV for parity with the
legacy EIP path's tail barrier (used by the next slice, vpc.add-nat).
Slice 4 of mulga-siv-129, sub-step b.
NATManager.AddEIP needs to block on `ovn-nbctl --wait=hv sync` after
writing the dnat_and_snat row so the NATS reply only returns once every
chassis has the rewrite flow. The legacy vpc.add-nat handler does this at
the tail of handleAddNAT; the manager has lacked it since slice 2.1.
NewNATManager grows a functional-options tail (Option / WithFlowsBarrier).
Defaults to a no-op for tests; production wiring in services/vpcd passes
waitForFlowsHV. AddEIP now invokes the barrier after AddNAT, logging at
warn level on failure to match the legacy handler's _ = waitForFlowsHV()
swallowing semantics.
Pre-work for slice 4 of mulga-siv-129 — without the barrier the NAT EIP
subscriber migration would lose the post-write flow-install gate.
applySGs now calls topology.Manager.EnsureSGPortGroup /
DeleteSGPortGroupByName instead of reaching directly into the OVN client.
Reconcile.Config gains a Topology field (required); the production caller
in services/vpcd passes the TopologyHandler shim, the reconcile package
tests construct a fresh topology.NewLiveManager bound to the mock OVN
client.
DeleteSGPortGroupByName is added to the topology.Manager interface for the
reconciler's orphan-removal path, which iterates raw OVN port-group names
without a groupID round-trip. The existing DeleteSGPortGroup(groupID)
delegates to it.
Resolves the TODO at apply.go:137 carried over from slice 2 of
mulga-siv-129.
Phase 2.6 / mulga-siv-129 slice 3. Rewrites vpc.create / vpc.delete /
vpc.create-subnet / vpc.delete-subnet / vpc.create-port /
vpc.delete-port / vpc.update-port-sgs NATS subscribers as thin
wrappers (≤30 lines each) over topology.Manager. Subscriber bodies
now: parse event → translate to spec → delegate to manager.
Deletes:
- vpcd.subnetGateway (and helpers_test.go + topology_test.go's
TestSubnetGateway block); parity coverage lives in
network/topology.TestSubnetGatewayCIDR.
- vpcd.reconcilePortSGs (the live manager already exposes the same
diff-then-transact via reconcilePortSGs on the L2 side).
- vpcd.TopologyHandler.dnsServer; lmDNSServer (passed via
topology.WithDNSServer to the live manager) is the live path.
Behaviour delta: handlers now strict-parse PrivateIpAddress /
MacAddress / CidrBlock at the NATS boundary and reject malformed
payloads instead of degrading to "no DHCP options". The reconciler
guarantees that field validity is upheld upstream of the publish.
Phase 2.6 / mulga-siv-129 slice 2. Rewrites the vpc.create-sg /
vpc.update-sg / vpc.delete-sg NATS subscribers in services/vpcd as
thin wrappers over topology.Manager (port group lifecycle) and
policy.SecurityGroupManager (ACL programming). Deletes the ~1000
lines of duplicated ACL builder and provisioning logic — its
authoritative copy lives in network/policy.
Surface additions:
- ovn.ErrPortGroupNotFound sentinel; mock + live GetPortGroup wrap
not-found via fmt.Errorf("%w: ...") so callers can use errors.Is.
- topology.Manager grows EnsureSGPortGroup / DeleteSGPortGroup
(resolves the apply.go TODO from §2.1 of the redesign plan).
liveManager implements them with GetPortGroup-then-Create /
GetPortGroup-then-Clear+Delete idempotency.
Behaviour delta: the old provisionSG rolled back the OVN port group
on AddACLs failure ("all-or-nothing"). The new path lets the port
group survive and relies on network/reconcile to retry EnsureSG on
its next sweep. The all-or-nothing fail-fast test cases are dropped;
ACL emission semantics are covered by network/policy/sg_test.go.
Move the topology.Manager implementation out of services/vpcd/topology_manager.go
into network/topology/manager_live.go as a standalone liveManager constructed
via NewLiveManager(ovn.Client, opts...). Inputs that varied per-handler
(DNS server resolution from the external pool) are now passed as functional
options (WithDNSServer).
TopologyHandler still satisfies topology.Manager but its methods delegate
to a cached liveManager. The shim stays until the rest of mulga-siv-129
routes NATS subscribers through topology.Manager directly.
Also exports SubnetGatewayCIDR + FormatDNSServerList from network/topology
so the reconciler in network/reconcile can share helpers with the live
manager (audit pass to follow per plan §6).
Test cases ported one-for-one from services/vpcd/topology_manager_test.go
to network/topology/manager_live_test.go; the vpcd-side test file is
deleted. New WithDNSServer test asserts the option propagates into
DHCPOptions rows.
Refs mulga-siv-129 (Phase 2.6 vpcd subscriber migration, Slice 1 of N).
Build spinifex/spinifex/network/reconcile/ package per Phase 2.2 of the
network layer redesign. Reads desired state from NATS KV filtered by
vpc.AZ (with legacy empty-AZ matches-all rule), scans actual state from
OVN NB DB, diffs and applies with VPC → Subnet → Port → SG → IGW →
EIP/NATGW topological ordering.
Atomic port-group join via CreateLogicalSwitchPortInGroups closes the
racy gap the legacy scanENIPortMembership pass used to revive 30s later.
A 5-minute drift goroutine (leader-gated via JetStream KV CAS) replaces
the old 30s ReconcileSGsLoop.
Adds AZ field to VPCRecord stamped at create time. Empty AZ on pre-Phase
2.2 records matches every local AZ, so no migration pass is required.
Replaces and removes the 5-pass startup sequence in services/vpcd:
- Reconcile + ReconcileFromKV
- ReconcileSGsOnce + ReconcileSGsLoop
- RetrofitAllExternalLocalnetOptions
- RetrofitAllGatewayPortNetworks
IGW fresh-create continues to flow through the legacy NATS handler path
(handleIGWAttach) so the dhcpManager wiring stays intact until Phase
2.3; the reconciler only rebinds gateway-chassis on existing IGW
topology.
Closes mulga-siv-125.3.2.
Pure additive — new package, no topology.Manager changes, no rewiring of
existing vpcd handlers. IGWManager builds the external switch + localnet +
gateway LRP + default route + chassis HA, with a flows barrier callers can
inject (production: ovn-nbctl --wait=hv sync). EIP/NATGW are thin L5
wrappers over policy.NATManager. GatewayIPAllocator interface lets the
DHCP-backed allocator stay in vpcd until the DHCP-mgr removal bead lands;
LinkLocalAllocator + StaticRangeAllocator ship here.
Introduce network/policy as the data-plane policy layer (ADR-0006 L3).
Three managers, all backed by network/ovn:
- SecurityGroupManager: clear+add ACL replacement on an existing port
group; port group lifecycle stays with L2 (topology.Manager).
- NATManager: bound to one NATMode at construction (derived from
host.UplinkMode). Distributed sets logical_port/external_mac on EIP
dnat_and_snat rules; centralised leaves them unset. Per-EIP, NAT GW,
and IGW-default SNAT entrypoints; all deletes idempotent.
- RouteManager: AddStaticRoute is read-then-decide so retries no longer
duplicate rows (closing the long-standing non-idempotency bug in
vpcd/topology.go's IGW default-route path).
ACL priority constants and infrastructure ACL builders move from
vpcd/{security,acl}.go into policy/acl.go with their semantics preserved
(default-deny 900/800 logged, DHCP-allow 1050, tenant 1000). No vpcd
wiring changes here — additive only; the reconciler (bead .3.2) and
network/external (bead .3.4) will consume these managers.
bead: mulga-siv-125.3.1
Phase 1 deliverable for mulga-siv-125.2. Introduces network/host (L0 of
ADR-0006): UplinkMode enum, Wiring interface, and Physical/Veth
implementations with injectable Runner + InterfaceReader for testability.
Not yet wired into daemon/vpcd — Phase 2 replaces daemon.SetupComputeNode
and vpcd's resolveExternalCIDR with calls through this package.
Add spinifex/network/topology with Manager interface, VPC/Subnet/Port
specs, and OVN object naming helpers covering the L2 stable contract
(§7 of the redesign plan). Phase 1 keeps existing in-tree OVN names
(rtr-, ext-port-, sg_) and notes the §7.3 targets for a later
reconciliation migration.
TopologyHandler in services/vpcd grows EnsureVPC / DeleteVPC /
EnsureSubnet / DeleteSubnet / EnsurePort / DeletePort /
SetPortSecurityGroups methods that mirror the corresponding NATS
handlers' OVN ops with Spec inputs instead of nats.Msg envelopes,
satisfying topology.Manager via a compile-time check. Existing handlers
are unchanged; the duplication is short-lived (Phase 2 collapses them).
Smoke tests in topology_manager_test.go cover the idempotent create
path, delete cascade, and declarative SG membership move. Deliverable:
TopologyManager.EnsureVPC/Subnet/Port callable; all existing tests
green.
Second sub-step of Phase 1 of docs/development/feature/spinifex-network-redesign.md
(bead mulga-siv-125.2).
