feat(network): ADR-0006 layer redesign + IPsec/OVN hardening (#255)
* refactor(vpcd): remove macvlan bridge mode
Macvlan was a single-NIC SSH-safe hack that predated veth mode and was
never selected by any active config path. Deletion is Phase 0 item 1 of
the network layer redesign (mulga-siv-125.1).
Removed:
- BridgeModeMacvlan const + setMacvlanMAC + ifaceIsMacvlan probe
- Macvlan MAC alignment block in launchService (only fired on dead path)
- Macvlan branch in detectBridgeMode + matching tests
- Macvlan duplicates of IGW/AddNAT centralized-NAT tests (veth versions
already cover the same path)
- --macvlan flag + macvlan case branch in setup-ovn.sh
Refactored:
- useCentralizedNAT() now == BridgeModeVeth (was != BridgeModeDirect);
verifyBridgeMode already rejects empty/unknown at startup
- Three IGW-pool tests now explicitly WithBridgeMode(BridgeModeVeth)
(previously relied on empty-mode defaulting to centralized)
Kept intentionally:
- Deprecation notes in docs/compute/vpc-networking/README.md
- Legacy macvlan-interface cleanup in reset-dev-env.sh + ansible
teardown role (migration for operator systems with stale spx-ext-*
interfaces from pre-veth installs)
* feat(vpcd): resolve external CIDR at startup with bounded retry
Block service start until the WAN bridge has an IPv4 address, with a 30s
retry window. Phase 0 item 2 of the network layer redesign
(mulga-siv-125.1). Guards the boot race where vpcd starts before
systemd-networkd finishes DHCP on br-wan, or before netplan applies a
static config.
Skipped when ExternalMode is empty (overlay-only deployments).
Forward-compatible with ADR-0006: the new resolveExternalCIDR /
externalCIDRFromBridge helpers become the backing implementation of
HostWiring.ExternalCIDR() once the network/host package lands in Phase 1.
Until then the resolved value is only used to fail-start on missing
uplink.
* fix(vpcd): cover external CIDR startup paths
Extract launchService's CIDR-resolve block to ensureExternalCIDRReady
helper so it's unit-testable, and add direct tests for
externalCIDRFromBridge (loopback + unknown-interface) to exercise the
original literal body. Closes the diff-coverage gap on Phase 0 commit
15b564d which left these paths unreachable from unit tests.
* refactor(network/ovn): extract L1 OVN client to network/ovn package
Move OVNClient interface, LiveOVNClient, ACLSpec, ErrNATNotFound and
namedUUID helper from services/vpcd to a new spinifex/network/ovn
package. The mock relocates to spinifex/network/ovn/mock as a
sub-package. Storage fields on the mock become exported so vpcd tests
can continue to seed/inspect state across the new package boundary.
services/vpcd retains thin type-alias and var-alias shims so existing
callers compile unchanged; Phase 2 removes those shims as vpcd is torn
down.
Adds -coverpkg=./spinifex/... to test-cover so cross-package test
exercise of mock methods continues to count toward coverage now that
the mock lives outside vpcd.
First sub-step of Phase 1 of docs/development/feature/spinifex-network-redesign.md
(bead mulga-siv-125.2). Pure refactor; no functional change. All
existing tests pass; preflight green.
* feat(network/topology): TopologyManager interface + vpcd adapter
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).
* feat(network/host): L0 HostWiring interface + physical/veth impls
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.
* feat(network/policy): L3 SecurityGroup/NAT/Route managers
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
* feat(network/external): L5 IGW/EIP/NATGW managers
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.
* feat(network/reconcile): L6 intent-actual reconciler replaces 5-pass startup
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.
* refactor(network/topology): promote live Manager impl to network/topology
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).
* refactor(vpcd): collapse SG subscribers onto network/{topology,policy} managers
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.
* refactor(vpcd): migrate VPC/Subnet/ENI subscribers to topology.Manager
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.
* refactor(network/reconcile): drive SG port groups via topology.Manager
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.
* feat(network/policy): add FlowsBarrier option to NATManager
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.
* refactor(vpcd): migrate NAT GW subscribers to policy.NATManager
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.
* refactor(vpcd): migrate EIP NAT subscribers to policy.NATManager
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.
* refactor(vpcd): migrate IGW subscribers to external.IGWManager (partial)
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.
* feat(ec2/instance): honor AssociatePublicIpAddress per-NIC override
RunInstances --network-interfaces "AssociatePublicIpAddress=true|false"
was silently ignored, only subnet.MapPublicIpOnLaunch gated public IP
assignment. AWS contract is per-NIC override wins.
Extend TestPrepareRunInstances_PublicIPAutoAssigned to table-driven
3 cases: subnet true no-override, subnet false override true, subnet
true override false.
* refactor(config): drop upstream-DHCP config surface (static WAN pool only)
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.
* refactor(vpcd): delete dhcp_manager + DHCP gateway-LRP path (Slice C)
Removes upstream-DHCP-client gateway-LRP allocation in favor of static
WAN-pool allocation (StaticRangeAllocator). Part of bead mulga-siv-125.3.3.
- delete services/vpcd/dhcp_manager.go + dhcp/ subpackage (~865 lines)
- delete allocateGatewayLRPIPViaDHCP + releaseGatewayLRPLease paths
- drop ExternalPoolConfig.Source + DhcpBindBridge + IsDHCP() fields
- drop ExternalIPAllocation lease fields (Expiry/ServerID/HWAddr) and
ExternalIPAMRecord.Source
- drop NewExternalIPAM nc *nats.Conn argument; update all 4 call sites
- rename verifyBridgeMode local dhcpBindBridge -> wanBridge; update error
strings and tests
Slice D (delete attachIGWLegacy + dispatcher) intentionally deferred.
* refactor(vpcd): delete attachIGWLegacy + IsDHCP stub (Slice D)
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).
* feat(ipam): Purpose field on every IPAM record (Slice B)
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.
* refactor(daemon): tombstone obsolete spinifex-dhcp-leases KV bucket
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.
* feat(config): add network.ipsec_enabled cluster flag (default 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).
* feat(admin): IPsec peer cert generator signed by cluster CA
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.
* feat(admin): wire IPsec peer cert into admin init + join paths
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.
* build: install openvswitch-ipsec for OVN native IPsec
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.
* feat(daemon): enable OVN native IPsec on intra-AZ Geneve at startup
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.
* test(e2e): multinode IPsec wiring + xfrm SAs + ESP capture
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.
* fix(igw): write attachment State="attached" for AWS parity
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
* fix(reconcile): call AttachIGW when IGW topology missing
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.
* fix(test): align NewExternalIPAM call with 2-arg signature
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.
* fix(vpcd): EnsureSubnet must EnsureVPC first to avoid NATS race
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.
* feat(ansible): require --external-pool, drop NAT, forward EXTRA_VARS
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.

* fix(ipsec): guard ipsec_encapsulation on ovs-monitor-ipsec liveness
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

* test(e2e): sticky-skip downstream SSH tests when probe fails
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.

* fix(ipsec): use Debian unit name openvswitch-ipsec.service
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).

* fix(e2e): authorize default SG tcp/22 + icmp in single-node fixture
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.

* fix(network/reconcile): key DHCP_Options lookup by subnet_id not CIDR
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.
* fix(ipsec): enable openvswitch-ipsec at provision time, drop daemon write
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.
* chore: unblock preflight on feat/network-layer-redesign
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

fix(vpcd): public-IP boot race + DHCP DORA hardening (siv-33/34/36/37/38/39) (#177)
* fix(installer): emit kernel cmdline to ttyS0 alongside tty0 (mulga-siv-33)
GRUB_CMDLINE_LINUX in /etc/default/grub only listed console=tty0, so the
installed kernel printed nothing on serial after the GRUB menu. Headless
installs (CI, racks with serial-only IPMI, remote-dev SSH-to-QEMU) saw a
black screen forever and had no path to debug boot failures.
Append console=ttyS0,115200 — the last `console=` on the cmdline becomes
the system console, so ttyS0 wins on serial-only hardware while tty0
still receives output on local displays.
Plan: docs/development/bugs/iso-public-ip-boot-race.md
* fix(ipam): widen vpc.dhcp.acquire retry budget to 60 s (mulga-siv-34)
ObtainDHCPLease retried only 5 attempts × 1 s before returning a hard
error. On a cold ISO boot, NATS comes up well before vpcd's reconcile
leader-election + dhcp.Manager subscribe (typical 5–30 s, pathological
~60 s during full reconcile), so daemon's NewExternalIPAM races vpcd's
dhcp.acquire subscription and fails permanently — d.externalIPAM stays
nil for the daemon's lifetime, daemon_handlers_instance.go silently
skips all auto-public-IP allocation, and instances launch with no
public IP, no dnat_and_snat, and no NAT event ever published.
Bump maxAttempts to 60 with 1 s spacing; expose both as package vars
so tests can shrink the budget for fast timeout-path coverage. Pure
widening of the existing retry loop — no behaviour change on the
success path, only the worst-case wallclock when vpcd never comes up.
The dominant cause of slow vpcd starts (mulga-siv-33: systemd-networkd
not enabled in the ISO → veth pair vanishes on reboot → vpcd
crashloops) is fixed alongside this. A 60 s budget fits comfortably
above all observed healthy-startup times.
Plan: docs/development/bugs/iso-public-ip-boot-race.md
* fix(setup-ovn): declare Linux WAN bridge as NetDev so networkd-managed veth resolves Bridge= on reboot (mulga-siv-33)
The veth-mode reboot persistence drop-ins added in mulga-998.b were
incomplete: setup-ovn.sh wrote `15-spinifex-veth-wan.network` with
`Bridge=br-wan`, but never declared br-wan itself to networkd.
br-wan is created by `networking.service` (ifupdown via
`/etc/network/interfaces`, generated by `install.go writeNetworkConfig`),
not networkd. networkd's `Bridge=` directive requires the target to be a
known NetDev — when it isn't, networkd silently logs
`br-wan NetDev could not be found, ignoring assignment` and the veth
ends up with no master. vpcd's bridge-mode sanity check then fails on
every reboot.
Fix: also write `14-spinifex-br-wan.netdev` declaring br-wan as
`Kind=bridge`. networkd matches the existing kernel bridge by name+kind
(the `Failed to create netdev: File exists` log is harmless), and
`Bridge=br-wan` resolves on next boot. ifupdown still owns DHCP and the
IP — networkd just needs the NetDev declaration to enslave the veth.
The write is gated to avoid clobbering operator-managed networkd config:
if any other `.netdev` under `/etc/systemd/network`,
`/run/systemd/network`, or `/usr/lib/systemd/network` already declares
the WAN bridge by name, the write is skipped with a log line pointing
at the operator file. Cleanup hook also removes the new file when
switching away from veth mode.
Verified end-to-end via QEMU repro: clean install + first boot + reboot,
veth-wan-br master persists across reboots, vpcd starts cleanly.
* fix(vpcd/dhcp): enable AF_PACKET promisc on bridge for DORA (mulga-siv-33)
Real-world DHCP servers commonly ignore the BOOTP BROADCAST flag and
reply with a unicast OFFER addressed to the synthetic per-tenant chaddr
(e.g. 02:f3:...). A Linux bridge floods unknown unicast to slave ports
but does NOT pass it up to the bridge netdev unless IFF_PROMISC is set,
so vpcd's AF_PACKET socket on br-wan misses the OFFER and DORA times
out at 15s ("unable to receive an offer: context deadline exceeded").
Dev/CI didn't hit this:
- CI uses spx_wan_mode=static — no DORA via vpcd.
- QEMU dev DHCP servers (SLIRP/dnsmasq) honor the BROADCAST flag, so
their replies are L2 broadcast which the bridge always passes up.
Replace the three nclient4.New(iface, ...) call sites in Acquire/Renew/
Release with nclient4.NewWithConn(...) wrapping a custom AF_PACKET
DGRAM conn that calls SetPromiscuous(true). Promisc is per-socket
(per-DORA, ~15s) and refcounted by the kernel — auto-clears on close.
* revert(vpcd/dhcp): drop AF_PACKET promisc wrapper, restore nclient4.New

fix: admin-up veth-wan-ovs via networkd (mulga-998.b Fix 1 follow-up)
Fix 1 persisted the veth pair across reboot via
15-spinifex-veth-wan.{netdev,network}, but only configured
veth-wan-br. Its peer veth-wan-ovs had no .network unit, so
networkd left it unmanaged and admin-DOWN after reboot. That
cascades: peer goes LOWERLAYERDOWN, br-wan loses carrier,
external DHCP/NAT path broken — despite vpcd correctly
detecting mode=veth and the sanity check passing.
OVS does not admin-up external (non-internal) ports — that's
networkd's job. Pre-reboot the setup-ovn.sh 'ip link set
veth-wan-ovs up' made it work, but that doesn't persist.
Write a second unit 16-spinifex-veth-wan-ovs.network with
ConfigureWithoutCarrier=yes so networkd flips admin state
without taking ownership of bridge/address assignment (OVS
retains that). Cleanup paths in the non-veth branch of
setup-ovn.sh and reset-dev-env.sh updated to remove the new
unit too.
Verified live via 'networkctl reload': veth-wan-ovs and
veth-wan-br both UP, br-wan LOWER_UP. Reboot drill per
docs/development/bugs/dhcp-vpcd-issues.md 'Live drill 1'
still required to confirm persistence.

fix: persist veth-wan pair across reboot (mulga-998.b Fix 1)
setup-ovn.sh's veth branch creates veth-wan-br ↔ veth-wan-ovs but nothing
recreates the kernel interfaces on reboot. OVSDB remembers veth-wan-ovs
as a port on br-ext but the peer is gone — the external path silently
breaks and vpcd falls through to direct mode.
- setup-ovn.sh: write /etc/systemd/network/15-spinifex-veth-wan.{netdev,network}
in the veth branch so systemd-networkd recreates the pair on boot. Add
a single pre-case guard that rips down stale veth persistence + the OVS
port + the kernel veth whenever WAN_BRIDGE_MODE != veth, so mode
transitions are idempotent (D17).
- reset-dev-env.sh: delete the netdev/network units during cleanup so
`make reset` gives a truly clean slate.
- spinifex-vpcd.service: After=systemd-networkd.service openvswitch-switch.service
so vpcd's sanity checks see a populated kernel + OVSDB (D5).

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.

feat: veth pair bridge — link Linux bridge to OVS without conversion
setup-ovn.sh now detects whether the default route is on a Linux bridge or OVS bridge. When it's a Linux bridge (e.g. br-wan from cloud-init), instead of destructively converting it, the script creates an OVS bridge (br-ext) and links them with a veth pair. The Linux bridge keeps its IP, routes, and ports untouched — no WAN interruption. Also fixes all pre-existing lint issues (gofmt, ineffassign, errchkjson, gosec, modernize, whitespace) to bring golangci-lint to 0 issues. Tested: pool mode with static IP range on single-node (ben-banksia). VM gets public IP 192.168.1.201, SSH works, outbound internet works. |

refactor: setup-ovn.sh — replace br-external with configurable WAN bridge
Replace --external-bridge/--external-iface/--direct with: - --wan-bridge=NAME: OVS bridge for WAN traffic (auto-detected from default route if it's already a bridge) - --wan-iface=NAME: physical NIC to add to the WAN bridge - --macvlan: SSH-safe macvlan mode for single-NIC hosts Auto-detection logic: - If default route goes through a bridge (br-wan) → use it directly - If default route is a physical NIC → stop with guidance (never auto-move a NIC into OVS — may drop SSH) Bridge-mappings updated: external:$WAN_BRIDGE (was external:br-external). OVN logical network name stays "external" (no topology.go change needed). Encap IP now prefers br-vpc IP when available (dedicated VPC data plane). Part of mulga-739. Blocks VPC E2E work. |

feat: direct bridge mode — prefer over macvlan when WAN NIC != SSH NIC
Auto-detect bridge topology: if a dedicated WAN NIC exists (not used for SSH), add it directly to br-external instead of creating a macvlan. Direct bridge enables distributed NAT (DNAT on VM's own chassis) and eliminates macvlan workarounds (MAC alignment, gratuitous ARPs, centralized NAT bottleneck). - topology.go: bridge-mode-aware NAT and localnet port options - vpcd.go: auto-detect bridge mode, skip MAC alignment for direct bridge - setup-ovn.sh: --direct flag for physical NIC on br-external - reset-dev-env.sh: SSH NIC detection via SSH_CONNECTION |

fix: preserve DNS resolution after IP migration to br-external
When setup-ovn.sh migrates the WAN IP from a physical NIC to br-external, systemd-resolved loses its DNS association (DNS servers are per-interface). This breaks hostname resolution for everything on the host — git, apt, curl, SSH all fail. Now captures DNS config from the original interface before migration and re-associates it with br-external via resolvectl. Falls back to 8.8.8.8 if no DNS was configured on the original interface. |

feat: auto-detect network topology + DHCP gateway in admin init
spx admin init now works with zero external networking flags: - Auto-detects WAN interface, gateway, prefix from ip route - Auto-detects single-NIC vs multi-NIC mode - Defaults to nat mode with DHCP for gateway IP - Prints detected topology with interface roles setup-ovn.sh gains --dhcp flag: obtains a DHCP lease on the macvlan/bridge interface for the OVN gateway SNAT address, then writes gateway_ip into spinifex.toml. Tested on VM: macvlan gets separate IP from router DHCP, host keeps its original IP. Three tiers of external networking: - Zero flags: auto nat+DHCP (VMs get outbound internet) - --external-pool=start-end: pool mode (VMs get public IPs) - --no-external: overlay only (no internet for VMs) |

feat: Phase 7 — single-NIC macvlan bridge strategy
Add --single-nic flag to setup-ovn.sh. When used with --external-bridge,
creates a macvlan sub-interface (spx-ext-{iface}) in bridge mode off the
host's NIC instead of adding the NIC directly to br-external. The host
keeps its IP — no migration, SSH-safe.
Strategy selection:
- Dedicated NIC: --external-iface=eth1 (add directly)
- Single NIC: --external-iface=eth0 --single-nic (macvlan)
- IP migration: --external-iface=eth0 (legacy, no --single-nic)
Add single_nic bool field to VPCDConfig for per-node config. Different
nodes in a cluster can use different strategies. Unit test verifies
single_nic parsing alongside external_interface.

Add commented [network] section and external_interface to spinifex.toml config template for discoverability. |
