Ben Duncan	7163f7d62d	feat(oci): run Spinifex on Oracle Cloud, and fix the public-address and NAT gateway lifecycle (#1108) ... * feat: ship uninstall-spx.sh and fix the OCI bring-up path Adds scripts/uninstall-spx.sh, the inverse of setup.sh: it removes the software where node-reset.sh clears state and leaves the node installed. An operator who installed with `curl ... | bash` had no teardown path at all. State teardown is delegated to node-reset.sh rather than reimplemented, and setup.sh now ships both to /usr/local/share/spinifex so they are reachable without a checkout. It refuses on a multi-node cluster and --yes does not override that: a flag meaning "don't ask me" must not also mean "ignore a safety property". /var/lib/spinifex and every apt package are kept unless asked for, and both opt-ins confirm separately even under --yes. Proved by a full uninstall/reinstall round trip on dev-oci, which found two bugs neither prod nor dev-prod can reach, because both are ISO-installed: node-reset.sh exited 2, silently, at its last step and after the wipe. setup.sh creates the spinifex *group* and the spinifex-* service users but never a *user* named spinifex, so `getent passwd spinifex` exits 2 and pipefail carried it into set -e. The uninstaller broke openvswitch-switch on its first run by removing the socket-perms helper while leaving the drop-in referencing it, failing the unit at step EXEC with status 203. Fixed on both sides: the uninstaller removes drop-ins it wrote into other units' namespaces and restarts anything it failed, and setup-ovn.sh writes ExecStartPost=- so a missing helper can never stop another package's daemon. setup-ovn.sh also learns the shape OCI needs: when --wan-bridge names a Linux bridge it links it to OVS with a veth pair instead of enslaving the NIC, so the VNIC keeps its MAC identity and netplan keeps owning the addresses. It now fails on OVS datapath errors instead of reporting success, and the --management demotion guard keys on /etc/default/ovn-central rather than on database presence, which the ovn-central package creates on every node. Tests: scripts/uninstall-spx_test.sh, wired into make test-build-scripts along with shellcheck over the four scripts that ship to every node. * feat: allocate external IPs from the Oracle Cloud API An OCI VNIC drops any packet whose source is not a registered private IP object on it, so an external pool cannot be range math there — the address has to be created through the provider before it exists at all. Add source = "oci" and the allocator behind it. One allocation is two OCI objects: a secondary private IP that rides the wire, and a RESERVED public IP attached to it that the internet reaches. Allocate returns the public address because that is what AWS semantics are about, and records the pair so the host plumbing and release path can find the private half. The OCI objects are created before the binding is written, and dropped after it on release — both orders chosen so a crash leaves a discoverable leak rather than a record that lies. Reconcile squares the two on startup and is required, not optional: a leaked reserved public IP bills and holds one of the 50 per-region slots with nothing referencing it. It never touches an object without our display-name prefix, because the reference host carries operator-created secondaries on the same VNIC. Resolve the VNIC from an interface name by MAC through IMDS rather than by Oracle's VNIC ordering, which is not a documented contract. Generalise ExternalIPAM.EnableDHCP into InstallAllocator so the OCI wiring is not a second single-purpose installer. * fix: refuse source = "oci" outside routed mode, and cover the SDK path An OCI VNIC accepts exactly one MAC, its own, and delivers every inbound frame to it regardless of which of its addresses the packet is for. Measured on the reference host: an internet source reaches 10.200.0.144 as router-MAC to VNIC-MAC, the public address never appears on the wire at all, and every off-subnet destination resolves to the same next hop. Pool mode puts a per-VPC gateway LRP MAC and a per-rule external NAT MAC on the uplink and ARPs for the address, which policy.go:50 justifies with "the Linux bridge learns the per-rule external MAC on the veth port like any other MAC". An OCI VNIC does not learn MACs; it accepts one. So a pool-mode guest's egress is dropped and its ingress never reaches OVN. Routed mode keeps the address on the host, which already wears the VNIC's MAC. Pinning every LRP to that MAC does not rescue pool mode: they share one external logical switch and OVN resolves inbound frames by an L2 lookup on it, so duplicate MACs work for one VPC and silently misroute past that. The refusal names the MAC reason, because a refusal that only says "use nat mode" reads as arbitrary and gets worked around. Also test the SDK request shapes against a local endpoint. Two of them are wrong in ways reading does not catch: pagination stopping early reports a partial VNIC to reconcile, which then drops live bindings, and a nil privateIpId on detach is omitted from the body entirely, so OCI reads the update as a no-op, returns 200, and leaves the address attached and billing. * fix: install host firewall rules where a distro's catch-all reject cannot precede them Oracle's Ubuntu cloud image ships a catch-all REJECT in both INPUT and FORWARD. Two Spinifex datapaths were silently dead behind it on any such host. EnsureNATEgressRules probed with -C and appended with -A, so its ACCEPT rules landed after the REJECT and never matched: 24113 packets on the reject, 0 on both accepts, and guests had no egress. The comment named the case it did not handle, anticipating a FORWARD policy of DROP — which an append does survive — rather than an explicit REJECT rule, which it cannot. Insert at the head, and drain existing copies first, because a rule an earlier build appended still satisfies -C and would otherwise stay stranded across an upgrade. Nothing opened INPUT for the IMDS endpoints at all. The responder binds .254 and .253 per instance on the ime- devices, so guest requests are locally delivered and meet INPUT. Requests arrived and no reply ever left; cloud-init spent 490s timing out and reported the endpoint as disabled. With one wildcarded accept the same image boots in 18.6s and finds its datasource. The natuplink e2e check had the same blind spot the code did, asserting -C and therefore presence but never position. It now asserts the accepts precede the first reject. * feat: OCI address pairs, and an IMDS remap so the host keeps its own metadata An OCI external address is two objects, not one: a RESERVED public IP that OCI 1:1-NATs upstream and never puts on the wire, and a secondary private IP on the VNIC that the wire actually carries. Every AWS-facing record holds the public half; every datapath object must hold the private one. The mapping goes in policy.natManager and nowhere else. AddEIP, DeleteEIP, PruneOrphanEIPs and the HostEIPBinder all converge there, and reconcile rebuilds the rule set from AWS-facing intent on every pass — so a correctly mapped rule installed further upstream is swept on the next reconcile and replaced with one matching an address that never arrives. The seam is a DatapathResolver defaulting to identity, so every non-OCI deployment is unchanged. A resolve failure is fatal: falling back to the public address would install a rule that reads correctly in ovn-nbctl and blackholes. ocinet.Lookup is the OCI side — read-only, KV-backed, no client and no credentials, because vpcd is a different process from the daemon that owns the allocator and the bindings record is all either would consult. Two live bugs the in-memory test store was hiding, both found by making the fake report ErrNotFound the way the real store does: - KVStore.Mutate could not create, so every pool failed its own first allocation after OCI had already created and billed the pair. - Reconcile treated a missing record as a failure, aborting the one pass that exists to find an object created before its binding was written. Guest IMDS must stay on 169.254.169.254, which is also where a cloud host's own metadata service lives — the first guest launch made it a local address and took the host's metadata and DNS with it. The datapath is OpenFlow steered, so the guest-facing addresses stay put and only the host-side endpoint address moves, with a PREROUTING DNAT on ime-+ translating and conntrack un-NATing the reply. Off by default; identity when unset. The IMDS firewall rules move to vpcd. They are wildcarded over every endpoint rather than per-launch work, and spinifex-daemon holds no iptables grant and no CAP_NET_ADMIN by design, so attempting them aborted every launch. * fix: name the real constructor in the IMDS bind-address error, and mark the NAT datapath test in-package The error string pointed at DefaultHostBindAddrs, which does not exist — a caller following it would have looked for a symbol that was never written. nat_datapath_test.go reuses nat_test.go's in-package fixtures, so it carries the //test:in-package marker the package check asks for. * docs: index what each e2e suite proves Written because a datapath comment was read as an end-to-end behavioural claim and the suite that already answered it was found only after the wrong answer had been given. TestVPCEgressPaths/NATBaseline is the authority on private subnet egress, and nothing pointed at it. * fix: source-route an EIP's reply out the VNIC that holds it An EIP's reply carries the EIP as its source. On a host that pins its uplink with a policy rule, the reply took the main table instead and left by the wrong interface — which a cloud VNIC drops, because the address is registered on a different one. Ingress reached the guest and nothing came back. Every bind now mirrors the uplink's rule onto the EIP. The selector is the rule rather than the interface: both OCI VNICs sit in one subnet, so "the interface owning the EIP's subnet" names two of them, and two candidate rules is a refusal rather than a guess. A host with no source routing gets no rule and no change. * docs: name the setup-ovn recipe routed mode actually needs on OCI The OCI guide told operators to run `--wan-bridge=br-wan`, which is mutually exclusive with `--nat-uplink` and deletes the spx-nat transit veth routed mode runs on. The node then refuses to bring the uplink up, with an error naming the flag the guide should have used. Several messages also claimed routed mode is outbound-only with no public IPs. That stopped being true when the routed EIP path landed, and it reads as "what you are about to do cannot work" during the one init the OCI path documents. * feat: let routed NAT form a multi-node cluster, and carry every pool through formation Lifts the --nodes >= 2 refusal on --external-mode=nat. The refusal carried no technical justification -- it was a v1 scope decision -- but routed NAT is the only datapath a cloud VNIC can carry, so "routed NAT is single-node" had become "Spinifex on a cloud host is single-node". It is not fixed by lifting it. Measured on three OCI nodes: the cluster forms, all chassis register and guest-to-guest traffic runs at 7.1-7.7 Gbit/s, but every node claims every EIP, nodes disagree on the VPC's gateway LRP, and only the gateway chassis reaches its own guests. init now says so on stderr rather than refusing, because the refusal made the defects unreachable and therefore unfixable. Distributing the EIP datapath is the actual fix. Lifting it exposed a second defect that stops formation outright. NetworkConfig held nine flattened Pool* scalars and the init node set PoolName = "wan" unconditionally; routed NAT renders two pools and the one that matters -- nat-transit, carrying the gateway-LRP range -- was dropped. Each joiner got a single pool named "wan" holding the transit gateway and the detected WAN prefix, and the leader re-rendered its own config from the same struct, so all three nodes were wrong. Pools is now []admin.PoolData in render order, and PoolData gains json tags because it is on the wire now rather than a template input. * feat(install-node): add --external-mode so a cluster can be formed in routed NAT install-node.sh could not express routed NAT at all. It required --external-pool/--external-gateway/--external-prefix-len and passed --external-mode=pool to every spx admin init unconditionally, so the only supported way to form a routed-NAT cluster was by hand. --external-mode nat refuses the three pool flags rather than ignoring them, and threads --nat-uplink into setup-ovn.sh -- without it the WAN interface check rejects a physical NIC during formation, which is correct in pool mode and wrong in routed mode, where nothing is bridged. * fix(ocinet): stop each node deleting its peers' OCI addresses on startup Reconcile compares the binding record against the private IPs on one VNIC. The record is one key per pool and therefore cluster-wide, so on more than one node every peer's binding looks exactly like a binding whose objects OCI has lost. Each node dropped them, and direction 1 on the owning node then collected the now-unclaimed objects as leaks -- deleting the reserved public IP and private IP of a running instance. Observed on the three-node OCI cluster: node2's startup pass logged "collected a leaked address" for an address it had allocated ten minutes earlier and "dropped a stale binding" for one living on node3's VNIC. The damage did not stop at the OCI objects. With the binding gone, Lookup.DatapathIP returns the public address unchanged, so the OVN dnat_and_snat row carries the public address instead of the private half. Guest egress then leaves the VNIC sourced from a reserved public IP, which OCI drops because it enforces the registered source per VNIC -- and EnsureEIPSourceRoute no-ops too, since a public address shares no subnet with any host address. One destroyed binding takes out both directions. Binding.VNICID already exists for exactly this ("how a node that comes back from the dead tells mine from moved on without me") and Reconcile never consulted it. A binding is now only dropped when it names this node's VNIC; one naming no VNIC cannot be attributed and is left alone rather than guessed at. * fix(host): find the EIP's source-routing table when the uplink is held as a /32 uplinkSourceRuleFor identified the interface owning an EIP's subnet by finding a host address configured with a prefix that contains it. On OCI both VNICs sit in one subnet, so br-wan has to hold its address as a /32 -- a /23 there puts the subnet's on-link route in the main table at metric 0 and takes the whole subnet off the primary VNIC. A /32 contains nothing but itself, so no rule was ever found, no source rule was installed, and the reply left by the primary VNIC where OCI dropped it for carrying an unregistered source. The address is not the only record of who owns the subnet. The rule names a table, and that table holds the on-link route. Consulted as a fallback, only when the address prefixes matched nobody, so a host that already resolved this the direct way keeps its existing answer -- prod and dev-prod are unaffected. Only scope-link routes count. A default route covers every address and would make every source-routing table an equally good answer. * docs(oci): correct the multi-node story and name the oci_vnic_id constraint The nat-mode warning said EIPs and default egress were both broken on more than one node. Default egress is fine: delete a guest's dnat_and_snat row and it reaches 1.1.1.1 in 2.3 ms from a guest on any of three nodes. Only the public-IP path was broken, and the three defects behind it are now fixed. What remains is not a bug but the shape of the datapath: routed NAT centralises the EIP path on the VPC's gateway chassis, ext-shared is a localnet so the other nodes cannot reach it, and OCI drops any frame whose source is not registered on the VNIC it leaves by. So every node's pool must pin oci_vnic_id to the gateway chassis's VNIC rather than resolving its own. Say so in §5.3, where an operator writing the pool will read it, and in §9, where the cost is that a gateway change kills every public IP until the pools are repointed. The single-node cap itself is gone from the doc: a three-node cluster has been formed and measured, and the warning proceeds rather than refusing. * feat(nat): distribute the routed-NAT EIP path so it works on more than one node Routed NAT processed every EIP on the VPC's gateway chassis, and ext-shared is a localnet, so the transit segment a /32 route pointed into existed only on that one node. Measured on three nodes: all three claimed all three EIPs, the nodes disagreed on the gateway LRP, and only guests on the gateway chassis were reachable. The mechanism to fix it is not new. Pool mode already distributes EIPs by putting external_mac and logical_port on the dnat_and_snat row and letting OVN's ARP responder answer for the external IP on the external segment. Routed mode has an external segment too, the spx-nat veth pair, and it being per node is the distribution: only the node running the instance can answer ARP on it. So a routed rule is now distributed on the same terms as a pool one, and its host route becomes on-link on the transit veth instead of via a gateway LRP that may be on another chassis. bindHostEIP stops demanding that address for a distributed rule, which is what previously failed the bind on every node but one. vpcd plumbs only the ENIs local OVS reports as its own, asked of OVS rather than the Southbound DB because the question is about this host. The gateway LRP keeps its transit-pool address. Default egress routes through it and works across three nodes today, so making it link-local as pool mode does would break a working path to fix one distribution has already fixed. Pool and static are unmoved, and a test asserts that against the same input rather than leaving it to inspection. A rule with no MAC stays centralised, so a cluster part-way through an upgrade is never in a state neither shape handles. Beads: mulga-opyl7, mulga-la0pe * fix(nat): make routed-EIP host plumbing work on every node Three guests on three OCI nodes, one guest per node: only one was reachable. Two defects, both invisible on a single node. The transit veth took a random MAC per node, but OVN holds one MAC binding for the transit nexthop across the whole cluster — so every chassis addressed its egress to whichever node seeded the binding, and the other kernels dropped it at L2. The pair is node-local, so one locally-administered address everywhere is unambiguous; setup-ovn.sh pins it at creation and in the netdev unit, and EnsureUplinkPort repairs a veth made before that. Host routes and proxy-ARP also rode the leader-gated reconcile pass, so a node that never won the lease never plumbed its own guests' EIPs. BindHostEIPs does that half on its own loop on every node; Bind already leaves alone an EIP whose ENI is elsewhere, so two nodes never contend. An unresolvable address skips the sweep rather than shrinking it. Pool and static are untouched: the new pass is a no-op outside routed mode, and a test asserts it. Also adds --teardown and --dry-run to setup-ovn.sh, for re-running it on a node that is already tangled. It deliberately spares the NB/SB databases, /etc/spinifex, the system-id and the packages, and refuses to del-br a Linux bridge. * fix(nat): assert the transit MAC where vpcd actually runs it EnsureUplinkPort is never called in production — host.Wiring is constructed nowhere — so the repair landed in a path the deployed daemon does not take, and three nodes came back with three different MACs. vpcd re-asserts it beside the NAT egress rules instead, which is the routed-NAT branch that does run on every start. * fix(vpcd): make uplink-mode detection say what it saw, and check it detectBridgeMode logged only the branch it took, so a node detected as veth when it was wired for nat looked identical to one that was right. It now reports both probes every time, errors when a node carries both uplink veths (set up twice, and --teardown is the way out), and errors when external_mode and the wiring disagree — the datapath follows the wiring, so the config silently loses that argument. An explicitly configured bridge_mode gets the same cross-check, since nothing else ever compared it against the wiring. The vpc-networking doc now opens nat with "start with pool unless one of these applies" and gains a section on nat across more than one node; the admin warning for --external-mode=nat on two or more nodes says what was verified by hand and what is still uncovered. * test(nat): prove routed NAT delivers each node's own guests, on a cluster natuplink ran single-node only, which is exactly where the two defects that broke three nodes are invisible. It now admits ModeMultinode, and phase 9 takes a second shape there: a guest per node in a spread placement group, and for each one — its public IP plumbed by the node running it and by no other node, the route on-link with proxy-ARP answered there, a dnat_and_snat row carrying external_mac and logical_port, a TCP handshake in from another node, and the guest's own console verdict for egress. Every node's transit veth is checked against the one cluster-wide MAC before any guest boots. Single-node phase 9 gains the same row and on-link assertions, so the shape is held on both topologies. Two gates come from what three OCI nodes actually do: every node holds a gateway_chassis row for every VPC (the active one is the highest priority) and every node installs the VPC ingress route, so only phase 7 needs gating — it runs where the gateway port and the guest are both local, and logs which one is missing otherwise. Cell 20 is real-multi x nat with its own nightly step, leaving the permutation cells' suite set alone. * test(nat): run the VPC egress paths in nat mode, not pool mode only The single suite gated TestVPCEgressPaths and TestWANEgressSMTPBlock on external_mode = "pool", with a comment saying nat clusters have no EIP/NAT-GW support. They have had EIPs since the routed path landed, so the gate now asks whether the cluster can allocate public addresses at all — pool, or nat with a non-transit pool configured. The nat-single cell runs TestVPCEgressPaths beside natuplink, which is the only nightly coverage of a private subnet's isolation and its NAT gateway in routed mode. natuplink never creates a private subnet. * docs(config): list nat among external_mode values * fix(ci): renumber the multi-node nat cell off the bare-metal job Cell 20 is already the bare-metal single-node job, gated on the same cells input but declared in the workflow rather than e2e-cells.json. A matrix entry with the same number runs two unrelated jobs under one name, and naming 20 in a dispatch selects both. * feat(images): add Oracle Linux 10.1 and 9.8, and pin their catalog digests Oracle publishes its qcow2 checksums inline on an HTML page and ships no sums file, so the four new entries carry the expected digest in the catalog rather than a URL to fetch one from. Images gains ChecksumDigest for that, and the catalog import path verifies against it and says which of the two sources it used, so a recorded digest never reads as a fetched sums file. Pinning is safe here and only here: each URL names an immutable build (b291, b293, b178, b182) and never moves. aarch64 has a -kvm-cloud- build alongside the plain -kvm- one; the cloud build is the cloud-init image and is the one that matches x86_64's -kvm-. TestImageCatalogReachable HEADs every URL in the catalog from the general single-node suite. These artifacts live on hosts nobody here controls, so an upstream that retires a build breaks `spx admin images import` for a customer and nothing else in the suite would notice. It also asserts that every entry sets exactly one checksum source, and that no pinned entry points at a "latest" URL whose bytes would change under it. * fix(formation): carry bridge_mode onto the leader and every joiner applyNetworkConfig copied external_mode, external_interface and the pools out of the formation NetworkConfig but never bridge_mode, so a multi-node cluster wrote a spinifex.toml without the key while single-node init wrote it. Every node then fell back to autodetecting a mode that init had pinned. Nightly cell 30 caught it: TestNATUplink failed at the config phase on a spinifex.toml that did not contain bridge_mode = "nat". Deriving it from the mode rather than adding a NetworkConfig field keeps the leader and the joiners on the same rule single-node init already uses. * feat(ui): show how to ssh into an instance, and which user to use An instance detail page gave the addresses and the key pair name but never the login user, which is the one part of the command nobody can derive. It belongs to the AMI, not to Spinifex: nothing in the launch path creates or renames an account, so stock cloud-init applies the distro's own default_user. Oracle Linux is cloud-user, Debian is debian, Ubuntu is ubuntu, and guessing from the distro name gets two of those three wrong. The card resolves the user from the AMI's name and description, and an unrecognised image yields a placeholder rather than a guess, because a wrong username in a copy-paste command is worse than an honest gap. A private-only instance is called out as reachable from inside the VPC only, rather than presented as a command that will simply time out. * fix(nat): plumb host state for a NAT gateway's public address AddNATGateway installed the OVN snat row and stopped there. On a routed-NAT node the host is what delivers a public address, so an egressing private guest left with a source the host held no route back to, and the masquerade rule — which matches the transit 100.127.0.0/24 alone — never saw the packet. The gateway's address needs the same /32 route into OVN, proxy-ARP and FORWARD accepts an EIP gets. hostBindSpecs unions floatingIPSpecs with one deduped spec per NAT gateway address and feeds BindHostEIPs. It is kept apart from floatingIPSpecs deliberately: pruneOrphanEIPs and addLive read that set as the complete list of addresses allowed to hold a dnat_and_snat, and a gateway holds an snat, so widening it would stop the sweep reclaiming a stale row on an address later reused as a gateway's. AddNATGateway also binds directly, on both the create and idempotent-skip paths, so a fresh gateway is not dark for up to 30s waiting on the host EIP pass — and so a reboot that keeps the OVN row still replays the volatile half. Documents NAT gateways in nat mode in vpc-networking, and says at the head of that section that nat is a supported mode covered by nightly cells 19 and 30. * docs(oci): document Oracle Linux as a guest image, and that its user is cloud-user Four catalog entries, all UEFI. The login user is the one that catches people: opc is the default on the images Oracle publishes into OCI itself, while these are the generic KVM cloud images from yum.oracle.com, whose cloud-init default_user is cloud-user. Verified on 10.1 and 9.8 — opc, oracle and ec2-user are all refused. Also records why these four pin a checksum digest inline (Oracle ships no sums file, and each URL names an immutable build), why arm64 takes the -kvm-cloud- build, and that SELinux ships enforcing. * fix(reconcile): stop reading an unreadable intent as an empty one A wedged JetStream KV returned no keys for the ENI bucket while writes were still landing. loadPorts mapped that to an empty port map, pruneOrphanPorts read every guest LSP as an orphan against it, and every guest on the node lost DHCP and IMDS while the API kept answering and the instances stayed "running". The existing re-read guard did not help: it re-reads through the same path. Three defences, because no single one covers every shape of the fault. A failed kv.Get now fails the pass instead of dropping the record. Dropping one VPC narrows localVPCs, which filters out every ENI in it, which the sweep reads as permission to delete every guest port in that VPC — one failed read, same outcome, and it needs no exotic KV state. Unmarshal failures stay skips: that is a poison record rather than an unhealthy store, and failing on it would wedge reconcile forever. The port sweep now asks local OVS which taps are plugged in here and never deletes a port that has one. A running guest's port cannot be an orphan whatever intent says, and OVS is the one liveness signal that does not come through the KV read path the sweep is otherwise entirely driven by. Wired from vpcd; unwired callers fall back to the guard below. An unreadable OVS skips the sweep rather than deciding on intent alone. Each sweep also refuses outright when the keep set it would delete against holds nothing at all — no ENIs, no SGs, or no ports and no external IPs. That is the case local taps cannot cover, because the drift sweep is leader-gated and lists NB cluster-wide, so the leader holds no tap for another node's guest. The cost is real: a genuinely orphaned row now survives until one live record of its class exists. Leaking a stale row is the recoverable half. Three existing prune tests drove their fixtures to a wholly empty intent, which is now the refusal case; they keep one live record of the class so they still prove the prune. The Get-failure path has no unit test — there is no jetstream.JetStream fake in the tree and an embedded server cannot be made to list a key it will then refuse. * docs(oci): separate the two address quotas, and the principal that can read them The regional reserved-public-IP ceiling is tenancy-wide and does not grow with node count, so a cluster hits it before the per-VNIC 64, which does. Records the commands that read both, and that a detached reserved public IP still bills. Reading limits or usage needs a tenancy-level grant, which cannot be compartment-scoped the way the node's policy is. That is a second, read-only principal kept off every node, not an addition to SpinifexOperators. * docs(oci): give quotas their own troubleshooting section, and say we enforce none Spinifex hardcodes no address ceiling: it attempts the allocation and maps OCI's own refusal to InsufficientAddressCapacity. So a quota is raised with Oracle and nothing here is reconfigured or restarted — which is what an operator needs to know before it bites, not after. Separates the two quotas by how they scale: the regional reserved-public-IP default is tenancy-wide and raisable by ticket, the per-VNIC 64 is per node and is not. * fix(oci): follow a guest to its new node when its EIP moves OCI delivers a public address to whichever VNIC holds the private IP behind it, and nothing ever moved that private IP. Binding.VNICID was written once at allocate time, as the VNIC of whichever queue-group daemon happened to serve the AWS request, and never updated — so an address landed on the right node only by chance, and a guest that stopped and started elsewhere went dark while every OVN row, host route and firewall rule on the new node was correct. ClaimLocalAddresses closes the gap from the node that should hold the address. Local OVS decides ownership, the same authority the host EIP binder already trusts for the same question, and UpdatePrivateIp with a new VnicId does the move in one server-side call. The private IP OCID survives it, so the reserved public IP attached to it follows without being touched and the customer's address never changes. A loop per node, not leader-gated: the question is about this host's guests, and a node that never wins the reconcile lease would otherwise never claim the addresses of the instances it is running. * fix(oci): record which ENI an EIP is associated with An EIP is allocated bare and attached by a later AssociateAddress, so the OCI binding written at allocate time named no ENI and nothing ever filled it in. The address then stayed on whichever node happened to serve the allocation: the affinity pass could follow an auto-assigned address, which is allocated with its ENI, but never an EIP — the case customers actually use. BindOwner is on an optional OwnerTracker interface rather than Allocator, because only OCI has a notion of an address being delivered to one node. A static or DHCP address is on the wire everywhere its node can reach, those allocators do not implement it, and ExternalIPAM treats a pool that does not as a success with nothing to do. The same gap made the release owner guard inert for EIPs: it compares against a binding ENI that was always empty, so a stale teardown could free an address already handed to another instance. * fix(ec2): report the address an instance is actually reachable on Three faults kept DescribeInstances answering with the address launch assigned, whatever happened afterwards. The launch-time stamp lives on the stored ec2.Instance, and the stopped path only declined to add an address rather than removing one, so a stopped instance went on advertising an address it had released and that may already belong to someone else. The projection now clears it, and the NIC association with it, working on its copy so a restart can still report the address. The running path filled the public address only when it was nil, which the stamp never is, so an EIP could not be reported however correctly it was recorded. The runtime address now wins. And nothing told the rest of the system about an association: AssociateAddress wrote neither the ENI record, which is what IMDS and the network reconcile read, nor the instance record, which is what a describe answers from. The ENI write is direct; the instance write is a fan-out, because the queue-group worker that serves AssociateAddress is rarely the node running the instance. * fix(net): take the host EIP plumbing off a node its guest has left Bind refuses an EIP whose ENI is on another chassis; the prune beside it kept anything still wanted cluster-wide. A guest that moved therefore left the old node holding the /32 route into OVN and the proxy-ARP entry on the uplink, with nothing that would ever remove them. On a shared segment that node goes on answering ARP for an address another node is now serving. The two halves now ask the same question by the same authority, in the loop that already runs per node. An unreadable local OVS is not a yes: tearing down a live address on a guess would fire everywhere at once, so it keeps the binding and the next pass tries again. A binder with no chassis test behaves exactly as before, and a centralised EIP is exempt because it hairpins through the gateway chassis and every node plumbs it legitimately. * fix(net): refuse to free an Elastic IP on behalf of a departing interface Releasing an instance's public address on teardown releases it by address, scoped to the ENI holding it. Since an association now writes the EIP onto the instance record, that address is the EIP — so terminating an instance gave a customer's Elastic IP back to the pool while describe-addresses still reported it as theirs, free to be handed to another guest. The existing ownership guard cannot catch this. It only fires when the stored allocation already names an ENI, and an EIP is allocated bare and associated later, so the stored ENI is empty and the guard passes straight through. The distinction that holds is who is asking. ReleaseAddress is the address's own owner and names no interface; instance teardown names the interface it is tearing down. So a release that names an owner may free an auto-assigned address and never an EIP, which is enforced in each of the three allocators. DHCP needed the scope carried on the wire, since it releases by address and resolves the lease afterwards. Absent on an older caller, which reads as false and keeps the previous behaviour. Worst on the two providers where it is not recoverable: on DHCP the lease is the only thing holding the address and the server promises nothing about handing it back, and on OCI the address is a reserved public IP object that the release destroys outright. * test(e2e): prove an Elastic IP survives a stop and start Instance teardown releases the public address by value, and since the association writes the EIP onto the instance record, that release aims straight at the customer's Elastic IP. The allocator guards now refuse it, but nothing end to end proved the address comes back on a restart. The step goes inside EIPFlip, which already runs last on the shared public guest for the same reason a stop is safe there: the address the guest returns on is the allocation's, not the pool's. It runs on the static cells and the DHCP ones alike, and on DHCP it doubles as the only outside view of the lease still renewing while the guest is down. * feat: release an auto-assigned public address on stop, take a new one on start AWS lends an instance a public address for as long as it runs and gives it a different one on the next start. Spinifex kept the address across a stop, which holds a pool slot for a stopped instance and, on a DHCP pool, keeps renewing a lease nothing is using. A stop now offers the address back through the instance cleaner, which refuses anything an Elastic IP is behind — the EIP association record answers that, the same question an ENI delete already asks — and records on the VM that the start owes it a new one. A host drain keeps the address: Restore relaunches the guest on the next boot, and changing its address under it is an outage nobody asked for. The start allocates before the launch, so an exhausted pool refuses the start rather than booting a guest the customer cannot reach, adopts an Elastic IP associated while the instance was stopped instead of assigning a second address beside it, and hands the address back if the launch then fails. e2e: a StopStartAddress stage on the public guest asserts a stopped instance reports no address and comes back on a different one from a static pool, and a StopStartKeepsTheEIP step asserts the opposite for an Elastic IP. * docs: restructure the OCI guide around two deployment paths, with diagrams The guide had grown into a numbered wall with no shape: no frontmatter, no contents, and a reader with an OCI account had no way to tell where to start. It now follows the multi-node install template — overview, prerequisites, then the deployment path — and splits that path in two: Terraform for one node or three, which is the preferred route, and a manual single-node walkthrough for an instance that already exists. Both meet at one shared configuration section rather than repeating it. Two ASCII diagrams carry what the prose could not: one OCI instance with the whole AWS surface inside it, and three nodes with the same surface distributed, showing which plane each VNIC carries and how an address follows a guest that moves. The limits section was materially out of date and said so in the places that mattered most. Multi-node is no longer experimental, public addresses are no longer pinned to one node — each allocates on its own VNIC and the affinity pass moves the private half to wherever the guest is — and an auto-assigned address is now returned to OCI on stop, so a stopped fleet stops paying for addresses. What changed is recorded rather than quietly edited. The Terraform configuration moves in from the monorepo as scripts/terraform/oci-spx, so the guide points at something in this repository. Also marks the two new lifecycle test files in-package, with the reason each one needs to be: both substitute unexported dependencies. * docs: rework the OCI guide — SVG diagrams, Terraform variables, iSCSI and br-wan Replaces the two ASCII diagrams with SVGs in the house style, one for a single node and one for three. Renames the two deployment sections to Terraform deployment and Manual deployment, documents what the Terraform builds per node and every variable worth setting, and explains that the data volume is an iSCSI attachment rather than a disk. The manual path now covers the iSCSI login, the fstab entry and the netplan source routing that Terraform writes, and states what br-wan is for on a routed-NAT node: it names the VNIC for the OCI allocator and holds the registered addresses, but is never bridged into OVS. Opens with what Spinifex is and why OCI is worth running it on. * fix: make gateway convergence work on a multi-node routed-NAT cluster Three defects each stopped a multi-node cluster from ever attaching an internet gateway, and all three produced the same uninformative symptom: `terraform apply` sitting on `aws_internet_gateway.igw: Still creating...` forever while every service reported healthy. ovn-northd was given only its local OVSDB socket as a client connection. A RAFT follower does not forward writes -- it answers "not cluster leader, trying another server" -- so with one entry in the list, northd stops translating Northbound intent into Southbound flows the moment database leadership moves to another node. Measured on the OCI cluster: SB_Global.nb_cfg seventeen transactions behind NB_Global.nb_cfg, with no chassisredirect port for any VPC created after leadership moved. setup-ovn.sh wrote the member list only when the caller passed --ovn-remote, which only install-node.sh did; it now derives the list from the live RAFT membership otherwise, and says so when it finds a single member, because that node needs a second pass once the others join. The gateway datapath probe ran wherever the reconcile lease landed rather than on the chassis owning the port. Both probes leave from the local uplink, and under routed NAT the transit subnet exists identically on every node, so a remote probe reported a healthy gateway as dead and aimed a repair at a datapath the node does not own. GatewayPortLocal gates it. On OCI the probe then ARPed the tenant-visible public IP, which the cloud NATs and which appears on no interface anywhere. The reconciler now maps the address through the same DatapathResolver the NAT rules are built from. Also adds DescribeVpcEndpoints, which the AWS provider calls on every VPC delete to sweep GuardDuty-managed endpoints; an InvalidAction there failed the destroy and stranded the VPC. The OCI guide gains a Terraform section recording which shipped workbooks were validated against a three-node OCI cluster and which are still open. * docs: record the validated Terraform workbook results for the three-node OCI cluster Six of the seven workbooks run against the OCI cluster pass, including the three the section exists to prove: RDS, ECS and EKS. Records nginx-alb and the clean eks-quickstart re-run, and names the two lifecycle gaps that bit during the run so an operator recognises them rather than reading them as a broken workbook. * fix: route the NAT gateway's SNAT source through the datapath resolver AddNATGateway was the one NAT path that did not map its external address to the one that rides the wire. Where the public half of an allocation is NAT'd by the cloud it is on no interface anywhere, so every private-subnet guest egressed with a source that was dropped, while the gateway reported available and DNS kept working because the VPC resolver is host-local. The unmapped address also failed the host EIP sweep, which works in resolved addresses, so the bind was pruned as foreign on the next pass and reinstalled on the one after. The public half now survives as an external ID instead. Also restructures the OCI guide around numbered steps through to running Terraform, and moves the cloud-init and metadata sections into troubleshooting where they are read when something is wrong rather than followed when it is not. * fix: place a NAT gateway's OCI address on the node that forwards for it OCI drops a packet whose source is not a registered private IP on the VNIC it leaves from, so a NAT gateway's SNAT source has to be on the gateway chassis. Two independent placements decided those and nothing reconciled them: the address was created by whichever worker served AllocateAddress, while the chassis is a fixed ordering the reconcile pass asserts. On a three-node cluster that made private-subnet egress a coin flip, and the same Terraform passed or died depending on which node answered. The affinity pass already solves this for guests, by asking local OVS where the tap is. A NAT gateway has no tap, and it skipped anything with no ENI — which is exactly and only this address. The equivalent local fact is the VPC's chassisredirect binding, so ownership now has two answers rather than one, and an address that is neither a guest's nor a gateway's is still left alone. The VPC is recorded from the reconcile pass rather than from CreateNatGateway, because the answer is the gateway chassis and reconcile is what decides it. * fix: plumb a NAT gateway's host ingress only on its gateway chassis A NAT gateway's address has no ENI, so neither the bind's locality test nor the prune's could ever fire for it and every node installed its /32 route into OVN. Latent on bare metal, where pool addresses are disjoint from the node subnet; on a cloud that hands out the address from the nodes' own subnet it outranks the connected route and swallows node-to-node traffic. Give that address the same second authority the ocinet affinity pass has: the VPC's chassisredirect binding, read from the local ovn-controller. An unanswerable question still leaves the binding alone, so a single node whose gateway port is not yet claimed behaves exactly as before. The orphan EIP prune built its live set from ENI and user EIPs alone while also sweeping host ingress, so every drift pass tore down the ingress of every live NAT gateway and left it dark until the next host EIP tick. * fix: ask the gateway chassis only about a NAT gateway's address gatewayElsewhere skipped the NAT gateway marker it was named for and answered for every spec, so on a node that is not the VPC's gateway chassis every EIP — including a guest's, whose locality is its own port — was left unplumbed. Two of three nodes bound nothing. * test: assert the two private-subnet EKS workbooks in the tofu harness eks-https-ingress and eks-gitops-argocd put their workers in private subnets behind a NAT gateway, so a worker only registers Ready if its egress to the cluster endpoint and to ECR survives that path. That makes them the workbooks that catch a NAT gateway fault, and neither had an assertion, so neither could be run at all — run_workbook calls assert_<name> by construction. Both share eks-quickstart's readiness check, extracted unchanged. They also name the worker size node_instance_type rather than instance_type, and tofu rejects a -var for an undeclared variable outright, so the name is read from the config instead of kept in a list here. * test: count agents, not every node, when asserting EKS workers Ready The control plane is three K3s servers, so an unfiltered node count reaches a one-worker cluster's desired size before any worker joins — the assertion passed on exactly the failure it exists to catch, reporting "4/1 workers Ready". Filtering on the control-plane role label makes it 1/1, which is the number that says a node-group worker registered. Matters most for the two private-subnet workbooks, where the worker joining is the whole proof that egress through the NAT gateway works. * docs: record the two private-subnet EKS workbooks passing on OCI	2026-09-26 14:31:07 -05:00

Ben Duncan	2ba8f5e4ab	docs: separate the install guides from the reference material they had absorbed ... Both install guides had grown sections that were not install steps, which is what made the multi-node one hard to follow. Each now ends on a step that hands off to Setting Up Your Cluster, and the reference material moves under Administration where it can be read on its own. - Single-node and multi-node both end on a "Set Up Your Cluster" step rather than a trailing sentence. - The multi-node cluster-state check via `spx admin kv digest` is gone. Verification is now every node Ready, capacity pooled, and the AWS API answering. - "How Multi-Node Storage Works" becomes docs/admin/predastore-distributed-storage, expanded with the host and node model, the write and read paths, degraded writes, hinted handoff, repair, encryption at rest, and what each class of failure costs. - "Firewall and Cluster Membership" becomes docs/admin/host-firewall, expanded with the full public, cluster and encap port groups, how to narrow SSH, and which files under /etc/spinifex/firewall survive an upgrade. - Setting Up Your Cluster gains a closing step that arms the firewall and narrows SSH, so the securing work lands after a cluster that works rather than during the install. install-usb and vpc-networking followed the two moved sections to their new paths.	2026-09-18 10:58:25 -05:00

Ben Duncan	7ddcac53bb	feat: block outbound SMTP egress via platform OVN ACL (#1001) ... * feat: block outbound SMTP egress via platform OVN ACL Add a platform egress ACL that drops outbound TCP to 25/465/587 for public destinations on every guest, matching AWS's default outbound-SMTP block. The control is global by default with an operator-held per-VPC exemption; tenants cannot open the ports via a security group because the block sits above the tenant-allow priority band. Private destinations are always exempt. Config exposes blocked_ports_wan (nil defaults to [25,465,587], [] disables) and egress_block_exempt_vpcs. Adds unit tests for the ACL builder, the SG manager wiring and the config resolution, plus an e2e that digs gmail.com MX and confirms a 5s SMTP connect is blocked while other WAN egress works. * docs: note the multi-node sync + restart requirement for the egress block	2026-09-04 16:45:26 -05:00
Ben Duncan	828b5df4aa	fix: pause a guest on a backend I/O error instead of handing it EIO (#977) ... * fix: fail DRAIN when a volume seal failed shutdownAndUnmount logged the volume unmount error and returned nothing, so StopAll returned nil and the DRAIN phase ACKed success with vms_stopped set. The coordinator then advanced to STORAGE and stopped viperblock while the seal was still in flight, tearing the VBState envelope and leaving the guest unable to mount its root volume on the next boot. The deploy reported success. shutdownAndUnmount now returns ErrVolumeSealFailed when the unmount did not seal; QMP, PID-file, fw_cfg and telemetry cleanup stay best-effort. stopCleanup and stopOne carry it without aborting the rest of the teardown, since QEMU is already down by then, and StopAll aggregates the per-VM failures so handleShutdownDrain ACKs with Error set and never reports vms_stopped. volumeMounterAdapter.Unmount was the second swallow site: it logged each failed seal and returned nil unconditionally. It now attempts every volume and returns the aggregate, which is what the VolumeMounter contract already described. Terminate still tolerates a failed seal — the volumes are deleted next, so an unsealed block map loses nothing a caller can ask for. This does not fix the seal itself. It converts silent data loss into a refused upgrade that an operator can act on. * test: add the storagefault e2e suite for backend-outage guest survival Freezes predastore with SIGSTOP to hold connections open while answering nothing, which is the fault a timeout-free path cannot distinguish from a slow peer. On one node that is a total outage; on three it freezes every node but the guest's own, breaking the RS(2,1) shard floor. The suite writes and flushes a verifiable region before the fault and churns a separate unverified region during it, so an interrupted write is never mistaken for lost data. The root-filesystem load runs from the user's home rather than /tmp, which is tmpfs on this image and would move no bytes on the root device. * test: verify the root device is under write pressure, and size the outage The previous guard matched /^ *vda / against /proc/diskstats, where the device name is the third field, and read $7 which is ms_reading rather than sectors_written. It printed empty and asserted nothing, so a green run could not distinguish a surviving guest from an idle disk. It now samples sectors_written twice and fails unless it advances. The outage is sized from viperblock's absorption rather than guessed: a workload must fill DefaultMaxPendingBytes before backpressure engages at all, so a short freeze measures the retry budget rather than the fault. * test: add nbdkit fault injection to the storage-fault e2e suite The predastore freeze takes the whole storage cluster away from every guest on it, which is too broad to run beside anything else. Removing a single volume's NBD server is the same fault at one-volume scope: one host, one guest, nothing cluster-wide stopped. Both signals are here because they sit on opposite sides of the defect. SIGSTOP holds the socket open and answers nothing, so the guest blocks and no error reaches ext4. SIGKILL closes it, and QEMU's nbd driver at the default reconnect-delay of 0 fails requests at once, which under werror=report aborts the journal. Signalling is guarded: a pid is matched on comm, our plugin and the volume argument together, and re-confirmed immediately before the signal, because these hosts run nbdkit for other volumes and pids are reused. * fix: pause a guest on a backend I/O error instead of handing it EIO Every virtio-blk device was created with werror=report,rerror=report, so a backend outage was delivered to the guest as EIO. ext4 aborts its journal on that and remounts read-only, and the write that failed is simply gone. Under werror=stop QEMU pauses the VM and holds the failed request, so a backend that comes back resumes the guest with nothing lost. The boot drive, the cold-boot data volume and the hot-plugged data volume all move to stop. Alongside it the NBD transport gets reconnect-delay=30, which pauses requests rather than failing them while a storage process restarts on the same socket; on the legacy -drive form it has to be file.reconnect-delay, because the bare name reaches the raw format driver, which has no such option. The QMP heartbeat now recognises run state io-error and issues cont. After ten attempts the instance is reported impaired and the cadence drops to one attempt per ten heartbeats, but it never stops: QEMU holds the request for as long as the guest exists, so a backend that returns an hour later can still be resumed. The storagefault suite gains the fault this was written for — kill the volume's own nbdkit, hold, then put it back on the same socket — and it now verifies a sha256 region across the outage rather than trusting the guest to be reachable. Three harness defects went with it: the socket-liveness poll ran unprivileged against a 0770 directory and could never succeed, the relaunched socket was left 0755 where QEMU needs group write, and the two variants shared one guest so a fault in the first was diagnosed in the second. * test: cover the io-error resume policy * test: stop two parallel tests racing on the terminate backoff variable * fix: report a guest paused on a backend I/O error as impaired A guest held by werror=stop kept reporting ok on both status checks. QMP stays responsive while the guest is paused -- cont is being sent and answered -- so the QMP failure gate that DescribeInstanceStatus keys on never trips, and the one state a customer most needs to see looked healthy. Instance status now reports impaired/failed while the resume budget is non-zero, timestamped from IOErrorSince so impairedSince is when the guest paused rather than when it was escalated. System status reports impaired too: a backend I/O error is an infrastructure fault, not a guest one, and that distinction is what the two checks exist to draw. The counter is cleared by the first poll that sees the guest running, so both clear on recovery. * test: reap the relaunched nbdkit when the fault test ends relaunchNbdkit detaches the server with setsid so it outlives the SSH session that started it, and viperblockd never learned it exists. Nothing reaped it, so every run left an nbdkit holding a socket and a cache for a volume that was later detached or deleted -- four were found running on dev-prod against two detached and two deleted volumes. The PID is resolved from the socket path rather than the volume id, so a legitimate viperblockd server for the same volume is never the one killed. * test: prove the backend is serving before a fault is called cleared Thawing the process a fault stopped is not the same as restoring the service. The outage test treated SIGCONT as the end of the fault and went straight to judging the guest, so it passed while the cluster it ran on stayed unable to serve a single object for the next 35 minutes, and the next test would have inherited that. thawPredastore now puts and gets an object through every gate, with a budget, and fails the test if the backend does not come back. * fix: do not hand back a mount entry whose export is gone A volume whose unmount failed kept its entry in MountedVolumes while its nbdkit was gone. Every later ebs.mount then matched that entry and returned its socket path, so vmMgr waited for a socket nothing would ever create and the instance could not be started again — on dev-prod a guest stopped against a frozen backend was left permanently stopped, four start attempts failing identically on a socket the node had already removed. Drop the entry when there is positive evidence the export is dead: the socket is absent, or the recorded pid is not running. Neither can be true of a live export, so the double-writer hazard the guard exists to prevent is unaffected. Also make the durability test's pattern helpers report failures. The read dd sat in a pipeline, so its exit status was discarded and the harness hashed nothing and returned the empty-string sha256 as a checksum. * test: report the guest console when a restart never answers SSH A restart that reaches running but never comes back is indistinguishable from a dead root filesystem without the serial console, and the log is gone once the fixture terminates the instance. * fix: converge guest port datapaths concurrently, not one deadline after another Each guest port that misses its SB binding burns the full convergence deadline, and applyEIPs spent them in series. Three ports belonging to long-stopped instances therefore held a newly launched guest's EIP dark for the sum of them before its own probe started. AddEIP stays serial since it mutates NB. Only the waits fan out, bounded, and sb-cluster-state-reset is now serialised with a minimum interval so concurrent probes cannot each fire a cluster-wide resync. * fix: refuse a stale cross-node start after the owning node is gone The volume lease already refused a cross-node mount, but it is a liveness claim: 45s TTL, renewed every 15s. A node that dies holding un-uploaded writes stops renewing, and 45 seconds later nothing refuses a start elsewhere that loads a stale backend checkpoint. A failed seal now writes a durable marker naming the node holding the only current copy, cleared on a seal that reaches the backend and on delete. The lease covers a live holder, the marker a dead one. The refusal also reaches the caller instead of being flattened to ServerInternal, which told an operator to retry something that cannot succeed while the holder is down. * fix: keep the daemon's message when a start is refused Rebuilding the error from the code alone rendered the generic ErrorLookup text, so a refusal naming the node holding the volume reached the caller as boilerplate about attaching volumes. * fix(ec2): terminate detaches every DeleteOnTermination=false volume TerminateStoppedInstance skipped the detach for a non-Boot DoT=false volume on the assumption that Stop's Unmount had already cleared its attachment. Unmount only clears it when the seal succeeded, so a volume whose seal failed stayed in-use pointing at an instance that terminate then deleted, leaving it unreachable with no owner to release it. The running-instance path already detaches every DoT=false volume; the stopped path now matches it, and tolerates an already-gone volume the same way. DeleteVolume also keeps its provider error on the way out. The terminate reaper retries the delete every two minutes and logged a bare ServerInternal, which made a blob node being down indistinguishable from a transient fault. * fix(ec2): DetachVolume --force releases a volume whose instance is gone The ordinary detach routes to ec2.cmd.{instanceID} for the guest unplug, so a volume left attached by a part-way teardown could never be detached: the instance no longer runs anywhere and nothing answers. That also made it undeletable, since DeleteVolume refuses an attached volume. ForceDetachVolume already existed for this deadlock but was reachable only from account teardown. Force now falls back to it when the instance has no responder, which is the one case where clearing the attachment cannot strand a live guest. * fix(viperblock): unsealed writes steer placement instead of pinning a volume The dirty marker refused any mount from a node other than the one holding unsealed writes. Instance start already forwards to the node that last ran the instance and falls back after a 30s window, so that refusal turned a working fallback into a volume that could run nowhere once its owner was gone. It traded a rare data-loss risk for a permanent availability failure. The marker is now a record and a warning, not a gate. A takeover logs the previous holder and why it could not seal, then adopts the marker so the old node is no longer treated as the better source. Live exclusion is unchanged and still enforced by the lease. It is also written on open rather than on seal failure. A node killed mid-write never reaches its seal, so the old trigger left no trace in exactly the case the marker exists to describe. Adds 'spx admin volumes unsealed' to see which volumes would cost something if started elsewhere. * fix(viperblock): fence a volume whose lease moved instead of logging it The lease was checked once, at mount, and never again. A node that lost it kept its export up and kept writing into a volume another node owned, so both copies advanced and the backend settled it by arrival order. Losing a renewal now decides: another holder means tear the export down, no holder means the entry merely aged out, so reclaim it and leave the guest running. Fencing never seals — this node's copy is the stale one — and leaves the dirty marker for the winner to take over. This is not an epoch fence. It narrows the window from the 45s TTL to one renewal interval at no write-path cost; the backend still cannot refuse a stale writer. * fix(network): advertise EIPs so a recycled address is reachable The gateway switch port only asked ovn-northd to publish the router's NAT addresses in centralised and routed modes, so on a distributed cluster nothing ever announced an elastic IP. OVN still answers ARP for it, which is why a first-time allocation works and hid this — but no gratuitous ARP is sent when the address moves to a new ENI, so every host on the segment keeps resolving it to the previous holder's MAC until its cache ages out. Reusing an address from the pool then lands on a dead MAC and the instance is unreachable from outside. Distributed mode needs the option as much as the others: northd scopes each entry with is_chassis_resident(<vif port>), so the announcement leaves from the chassis running the instance rather than the gateway, which is what distributed NAT wants. Converge on the already-attached path too. AttachIGW returns early once the gateway port exists and nothing else rewrites it, so without that an existing VPC would stay silent for its whole life. Confirmed on dev-prod: setting the option moved three EIPs from unadvertised to carrying their correct external_mac, each scoped to its own ENI's port. * fix(viperblock): make the volume fence and its dirty marker ownership-safe Four corrections to the lease-loss fence, all found in review. Drop the reacquire path. Losing a lease and finding no successor was treated as a lapsed entry worth reclaiming, but leases.acquire returns the cached entry — already flagged lost, with a dead renewal goroutine — so the "reclaimed" lease renewed nothing and the node went on writing a volume it could not prove it owned. The two errors are not symmetric: a false fence costs one guest a restart, a false reclaim leaves two nodes writing one volume. Fence in both cases, and report which happened through the outcome attribute. Surrender a lease this node cannot confirm. Renewal only noticed a loss when the server rejected an update, so a node partitioned from NATS kept its export up while the TTL expired and another node took the volume. Track the last confirmed renewal and give the volume up once that ages past the point where the server may admit another owner. Bound the renewal call too, so a hung JetStream request cannot hold the goroutine past that point. Do not act on a kill that did not take. Both the fence and ebs.unmount removed the mount entry, released the lease and announced the result before knowing nbdkit had exited — the fence then reported a writer stopped that was still running, and the unmount sealed into a directory a live process was writing. Wait for the exit, and on failure leave the volume mounted and say so. An already-exited process now counts as success, which is what the caller asked. Give the dirty marker a generation. It recorded an owner and nothing to order two nodes' claims, so a node returning after a takeover could clear or overwrite the winner's marker and point placement back at the stale copy. Stamp the lease generation, refuse a write from an older one, and only clear a marker this node still owns. A marker that cannot be written now fails the open rather than leaving writes nothing records. * test(viperblock): cover the stall surrender and the unmount kill guard The two ownership cases the fence work left untested. A holder partitioned from NATS while the winner keeps it never gets an update rejected, so revision checking cannot see it — it has to give the volume up on its own clock. Pins that validity sits below the server TTL with room for a check in between, that a lapsed holder reports the loss as a stall rather than as a takeover, and that releasing a surrendered lease leaves the entry for whoever holds it now. The unmount side of the kill guard: sealing under a live nbdkit writes a state torn between two writers, so a kill that did not take has to fail the unmount and leave the entry mounted for a retry. * fix(e2e): keep the guest private key for as long as the key pair EnsureKeyPair computed the PEM path from the caller's directory but wrote the file inside the ensureOnce closure, which runs only on the first call. Callers passed a per-test artifact dir, and ArtifactDir removes that dir when the test passes — so the first test's success deleted the only copy of the private key while the key pair stayed registered, and every later call returned a path nothing had ever been written to. Guests after the first were then launched against a public key whose private half no longer existed, so the harness could never authenticate and gave up after the full five-minute budget. The guests were healthy and reachable on tcp/22 throughout, which is why this read as a storage or network fault for so long. The directory parameter was the defect, so it is gone: the PEM now lives in a directory the fixture owns and removes with the key pair, and no caller can supply one that is shorter-lived. Also reorder the killed-nbdkit teardown. The reaper registered its own cleanup after the detach registered one, so LIFO killed the block server before the platform detached the disk and DetachVolume then failed with "Node ... is in use". The detach cleanup now reaps once it is done. * fix: stop leaking an nbdkit export when recovery cannot adopt it Restart recovery adopts a guest's boot volume, then routinely fails the -efi volume with "claim lease: context deadline exceeded" -- JetStream is still catching up at daemon start and the KV claim runs on the client's 5s default. Recovery gave up on the first error and never retried, so the export stayed live with no registry entry. At terminate the unmount found nothing to seal, returned NotFound and killed nothing, and the process outlived its guest holding the volume and socket open. EFI is always the second volume adopted, which is why it was always the one that leaked. Two changes, because either alone leaves a hole: - rebuildMountedVolume retries the build (4 attempts, 3s apart) so a JetStream that is merely slow no longer orphans an export for the life of the process. - unmountVolume reaps a corroborated export for the volume it was asked to unmount when the registry has no entry for it, so an export orphaned by any means is still cleaned up. The reap goes through reapOrphanedNbdkit, which declines anything a live process references: at unmount the guest's blockdev may not be torn down yet, and killing the server underneath it strands QEMU. * test: hold the backend-serving probe and assert predastore readiness The backend-outage test declared the backend restored on one successful round trip through each gate. A gate can answer the request that arrives just after a thaw and then lose its blob peers under the load that follows, which is a backend that never recovered reported as one that did -- and that is what happened: the probe reported all three gates serving minutes before the guest was still taking BLOCK_IO_ERROR on every resume. The round trip has to hold across three rounds now, and the count restarts rather than decays when one fails, so a gate that serves and then stops is the failure the hold is looking for rather than noise it averages out. It also checks /readyz on each host and reports any failed check by name. The round trip only proves this workstation can write through a gate; it says nothing about which blob peers that gate can reach, and a gate one node short of the write floor serves a small object and fails a guest. A host that serves no admin listener is logged and skipped, since the port is optional configuration. * fix: scope predastore's admin port to the cluster plane in the host policy predastore's admin listener binds the host's cluster bind_addr and serves /healthz and /readyz unauthenticated. Readiness now names which blob peers a gate cannot reach, which is exactly the kind of topology detail 4432 is peer-scoped for, so 8660 joins it in the peer-scoped rule rather than the public one. * fix: keep resuming a paused guest at heartbeat rate after a long outage Past ten attempts the cont dropped to one per ten heartbeats, so a guest whose backend had come back could sit paused for another five minutes before anything retried it. Measured on dev-prod: the backend was proved serving through all three gates while the guest was still waiting on attempt 60, five minutes after attempt 50. The slowdown was there to avoid paying a failed I/O every thirty seconds on a backend still down. That is nearly free, and five minutes of downtime after recovery is not, so only the log line is throttled now. * test: fail the run when a key pair name resolves to more than one pair A create that lands twice leaves two key pairs with one name and different material. RunInstances resolves the name to one of them while the harness holds the private key of the other, and the only symptom is every guest in the run refusing the key at the SSH gate — five minutes of waiting per guest, four guests, and nothing anywhere naming the cause. Observed on dev-prod: two pairs created a millisecond apart, both named e2e-key-30de10ba. One DescribeKeyPairs after the create says so outright instead. * test: tolerate an already-released volume in the detach teardown Teardown runs DetachVolumeWait after a terminate that releases the volume itself, so the detach can arrive at a volume already on its way to available. That is the outcome it wanted, and treating the IncorrectState refusal as fatal failed a backend-outage run whose assertions had all passed — the guest came back, every acknowledged write verified, and the test still went red on the way out. VolumeInUse is still fatal: that one means the volume is attached somewhere it should not be. * test: carry the merged suites onto the reworked key-pair and account-scoped seams The diskperf suite arrived on dev calling EnsureKeyPair with the artifact dir this branch removed, and DeleteVolume's metadata lookup is account-scoped now, so the provider-failure test has to seed and delete under the same account. * refactor: make the fence outcome a type in one const block Four separate exported string constants with a paragraph of comment each, passed to RecordVolumeFence as a bare string. Group them, give them a FenceOutcome type, and take that type at both call sites so an arbitrary value can no longer reach the metric attribute. * refactor: move viperblockd's wire contract into a leaf vbwire package The daemon imported viperblockd for exactly two symbols -- the fenced volume subject and its event -- which put the storage service back on the daemon's dependency graph to name something it only listens for. vbwire holds the contract instead: the subject and event, the dirty bucket name and record shape, and the read-only listing an operator tool needs. It imports nothing from spinifex, so both the daemon and the admin CLI drop their edge to viperblockd entirely. cmd/service.go keeps its one, which is genuine: it constructs the service. * docs: drop a specific host name from the start-refusal comment Named a real dev-prod host in a comment and in test fixtures. Say what the name is instead. * ci: give storagefault a dedicated nightly cell The suite is eligible for both topologies and runs on the PR gate, but no nightly cell ran it: the permutation cells run a deliberately narrow subset and none of the dedicated suite cells named it. Cell 29, single-node, following eks/ecs/rds. It cannot join a permutation cell -- it SIGSTOPs a cluster-wide service, so every suite sharing that environment would report the outage as its own failure. * ci: run storagefault nightly on three nodes, not one The previous commit put its dedicated cell on a single-node runner. That was the wrong topology and the wrong justification: single-node is RS(1,0), where the shard floor cannot be broken and a cross-node takeover after a failed seal does not exist, so the two assertions worth having a dedicated cell for were the two it could not make. Cell 29 is now real-multi on ci-multi. It also corrects the claim that the PR gate already covers the multi-node case. The suite is eligible for both topologies, but e2e.yml's default suite list never names it, so it has never run there. A full pass is ~63 minutes on dev-prod bare metal, almost all of it deliberate waiting -- one test holds predastore SIGSTOPped for seven minutes -- which is too long to add to a gate that currently finishes well inside its budget. Nightly is where it belongs. Consequences: a per-cell timeout_minutes, defaulting to the previous 50, since 90 minutes of suite cannot run in a 50-minute job; the permutation steps gated on matrix.suite == '' so the dedicated cells do not also run them; and a Run Multi Suite E2E step that builds NODES_CSV from the tofu inventory and asserts the suite against E2E_SUITES_MULTI before running it. * fix: stop a startup KV race leaving vpcd serving keyless guests vpcd opens five KV buckets while NATS is still coming up, each attempt carrying a ~5s JetStream API deadline, and applied three different policies to the same failure: spinifex-vpc-enis was fatal, while instance-state, security-groups, subnets and vpcs each degraded silently for the lifetime of the process. A five-second blip during a cold start therefore decided how a node served metadata until someone restarted it. On dev-prod all three nodes hit this after a deploy. Two were saved by accident: their ENI bucket also timed out, so they exited 1 and systemd restarted them cleanly. The third's ENI bucket opened in time, so it never crashed and ran for hours with no instance record loader. With the local state file unreadable as well, every instance-backed IMDS leaf 404'd, cloud-init's crawl died on ami-id and fell back to DataSourceNone, and every guest launched on that node booted with no authorized_keys. kvstore.OpenWithRetry retries for a bounded window before any policy applies, logs the cause per attempt and the wait on a late success, wraps the last error with the bucket name, and returns at once on a cancelled context. All five opens use it. Failing to open the instance record space is now fatal, matching the ENI bucket: the dependency whose loss stops guests logging in should not be treated more leniently than the one whose loss stops ENI resolution. Also fixes the reason the fallback was load bearing at all. The local state file was written 0600 and vpcd reads it as a different user in the shared spinifex group, so the local-first path had never once worked and its mtime+size cache had never fired. It is 0640 now, set with an explicit Chmod so an inherited umask cannot undo it. Closes mulga-gtpzz, mulga-dhqxr. Still open: mulga-mm2oc, IMDS serving an unresolvable instance as "no key pair" with nothing logged. * fix: scope the ime-* firewall accept to IMDS and VPC DNS only The per-tap OVS demux delivers any guest packet addressed to 169.254.169.254 or .253 onto an ime-* host port regardless of L4 port, and iifname "ime-*" accept then admitted all of it. Every wildcard-bound host service — sshd, the AWS gateway, northstar, the console — answered guest packets on those addresses; only asymmetric reply routing kept the handshake from completing, and a guest could still drive northstar to recurse unthrottled. Scope the accept to IMDS (.254:80) and VPC DNS (.253:53), letting everything else fall through to policy drop. * docs: document the instance-to-host plane and how to protect it without the ISO The metadata/VPC-DNS link-local plane (169.254.169.254/.253) is served by host services and is invisible to a NIC-level or cloud firewall, since the traffic is intra-host on the OVS bridge. Explain that the ISO ships the scoping rule armed, that the binary installer ships the firewall off, and that a non-ISO install must enable it with setup.sh --firewall=on or firewall_enabled=true. Include verification from an instance and the host. * fix: withhold the IMDS meta-data listing when the instance does not resolve Every omission from the meta-data root is a positive claim about the instance — public-keys/ absent means "launched without a key pair", and cloud-init believes it, writes no authorized_keys and boots the guest keyless. So resolving the instance was best-effort for a listing whose whole meaning depends on it: a backend error or a miss shortened the listing instead of failing it, and nothing anywhere recorded that the answer was a guess. Withhold the listing with a 500 instead. cloud-init retries a 5xx and cannot retry a 200 that is merely wrong, so this converts a permanent silent failure into a transient loud one. servePublicKeys already had this policy for the leaf; the root is what contradicted it. A profile lookup that fails still serves the listing minus iam/, and now logs. The key pair is the field a guest cannot recover from losing, while a missing role surfaces through the credentials leaf, which reports the miss itself. Also stops the storagefault cross-node test failing on its own access path. It tolerates the pattern changing across a takeover, but readPattern needs sudo, and a volume opened from the backend checkpoint may predate cloud-init writing its sudoers drop-in — indistinguishable from an unreadable device at the dd call site. It now checks sudo first, and reads cloud-init's recorded datasource to tell a rolled-back root filesystem from IMDS never having answered, failing loudly on the latter rather than accepting it as storage loss. --------- Co-authored-by: brynmailer-mdc <bdm@mulgadc.com>	2026-09-03 19:45:33 -05:00
Ben Duncan	8b3c706ea3	docs: rework the multi-node install guide, fix cross-doc links ... Multi-node install - Lead with the fact that the guide builds a three-node cluster, and say how to go beyond three. The callout sits inside ## Overview because the docs site discards everything above the first section heading. - Replace the OVN-only sizing prose with a table covering all three distributed layers, and move the OVN control-plane detail into the VPC networking guide, linked from here. - Add minimum and recommended hardware. - Move the object storage layout to the end as background; it was the second thing a reader hit. - Collapse the ISO conversion notes from a section into one skippable box, now that --force is unconditional in Step 4 and the formation port needs no manual intervention. - Expand verification with spx get nodes and spx top nodes, including what to look for in each. - Drop the install-node.sh shortcut (internal tooling) and the "adding a node later" section (no good story yet). Corrections found while writing - Servers 4+ were described as running no database. They run predastore and viperblock like every other node; only the OVN database cluster is capped at three. Fixed in four places. - Step 4 never needed the firewall down: spx admin init opens the formation port itself for the formation window. Only Step 3's peer-scoped OVN ports are affected. - `nft list table inet spinifex_filter | grep spinifex_peers` could never match — the peer list is an nft define, expanded at load time. Anyone following it would have seen empty output and assumed the worst. - Disambiguate "database": with predastore, NATS and OVN all in play it needed qualifying throughout. - Align the example output region with the AWS_REGION the guide exports. Cross-doc links - Rewrite relative and category-prefixed links to the canonical /docs/<slug> form. The site publishes docs flat, so ../foo/README.md and /docs/category/foo both 404. - Point the six links to unpublished docs at the source repo instead. - Fix four fragments written against GitHub's anchor algorithm.	2026-08-21 14:14:28 -05:00

Josh Siviour	183a08353e	feat(network): harden routed-NAT v1 (VPC cap, e2e gate, docs) (#504) ... Three related nat-mode fixes: - ura01: nat-transit pool now emits gw_lrp_range_start/end. admin init sets 100.127.0.16-.254 (239 VPC gateways) instead of the auto-derived top-16 (~15). Adds GwLrpRange* to PoolData + the spinifex.toml template so operators can widen any pool. - 724mm: detectPoolMode returns true only for external_mode=pool. nat and disabled clusters now skip Phase 8b/8d, which otherwise failed on AllocateAddress UnsupportedOperation. - pnz2i: document that system instances (ECS/EKS/LB agents) are unsupported in nat v1 (require pool mode) in the vpc-networking README and COMMANDS.md; document the gw_lrp_range_* fields.	2026-07-10 22:57:21 +10:00
Josh Siviour	e1c4f85a36	feat: routed-NAT external mode with two-tier ingress (#475) ... * feat(network): add routed uplink mode, Routed wiring, and NAT egress rule helper * feat(external): route gateway LRP over transit pool and install VPC SNAT in routed NAT mode * feat(vpcd): support bridge_mode=nat (routed uplink, transit pool, egress rules) * feat(daemon): register EIP handlers unconditionally with disabled-mode stub; seed default subnet per external mode * feat(admin): support --external-mode=nat and suggest it for non-bridgeable uplinks * feat(scripts): add --nat-uplink routed mode to setup-ovn.sh * test(e2e): add routed-NAT single-node natuplink suite Covers the external_mode=nat lane end to end on a nat-initialized node: host transit wiring (veth, br-ext port, ip_forward, iptables egress rules), spinifex.toml contents, disabled EIP surface (empty describe-addresses, UnsupportedOperation on allocate), default subnet MapPublicIpOnLaunch=false, OVN gateway LRP + VPC SNAT on the transit /24, guest outbound egress proven via a serial-console probe (nat mode has no inbound path), and unique transit gateway IPs across VPCs. Suite self-gates on external_mode=nat; registered as e2e-natuplink and in SUITES_BUILD so it compiles in CI. Manifest entry stays commented until CI can provision a nat-mode environment. * feat(ovn): Address_Set CRUD and NAT exempted_ext_ips column Adds the exempted_ext_ips column (optional strong Address_Set ref) to the nbdb NAT model, Address_Set ensure/get with wait-op create semantics, and an in-place SetNATExemptedExtIPs update on the client interface, live client, and mock. Test NB schema gains the column and covers insert-resolves-UUID, converge, clear, and missing-NAT paths. * feat(policy): exempt address set on routed SNAT/EIP rows Adds WithSNATExemptSet so routed mode stamps exempted_ext_ips (the spinifex_nat_exempt Address_Set: transit /24 plus operator extras) on IGW snat and EIP dnat_and_snat rows, keeping VM replies to host-initiated flows un-NATted. AddSNAT gains an idempotency guard keyed on (router, VPC CIDR) with stale-IP replacement, and both AddSNAT and the AddEIP idempotent-skip path patch the ref in place on pre-existing rows. The set is a singleton strong ref and is never deleted. Non-routed modes are unchanged. * feat(host): VPC ingress route primitives for routed-NAT mode EnsureVPCIngressRoute / RemoveVPCIngressRoute manage the host route that sends VPC-CIDR traffic into OVN via the gateway LRP transit IP on the spx-nat veth. Replace/del semantics keep both idempotent; a missing route on removal is not an error. * feat(external): routed ingress leg on IGW attach/detach, reconcile-safe AttachIGW's routed leg now also installs the host VPC ingress route via RoutedIngressHooks, and re-runs on the already-attached path so the reconcile loop restores host routes (and patches legacy SNAT exempt refs) after a reboot — OVN state survives restarts but host routes do not. DetachIGW removes the route alongside the SNAT. vpcd wires the hooks and the spinifex_nat_exempt set (transit /24 + [network] nat_exempt_cidrs, validated nat-mode-only) exclusively in routed-NAT mode; pool/veth/direct pass nil hooks and are unchanged. * test(natuplink): Tier 1 host-ingress phase; docs for jumpbox pattern New Phase 7 asserts the automatic ingress tier: host route to the VPC CIDR via the gateway LRP transit IP, exempted_ext_ips ref on the SNAT row pointing at spinifex_nat_exempt (containing the transit /24), and — after opening the SG from the transit net (default-closed, AWS parity) — ping and an sshd TCP handshake against the instance private IP from the host, which proves the un-SNATted return path. Phase 8 additionally waits for the second VPC's ingress route to appear on IGW attach. vpc-networking README documents the jumpbox pattern, SG note, and nat_exempt_cidrs. * feat(config,admin): public wan pool alongside nat-transit Restructure admin config generation from single-pool scalars to a Pools slice so nat mode can emit both the transit pool and an optional public wan pool. nat mode now accepts --external-pool/--external-source (plus --external-bind-bridge/--gateway-ip when a public pool is requested), validated by the shared resolvePublicPoolFlags helper also used by pool mode. Transit pool always renders first so the IGW allocator picks it. Formation wire format unchanged (nat mode is single-node only). * feat(daemon): enable EIP service and auto-assign in nat mode with public pool External IPAM (and with it the real EIP service, RunInstances public IP auto-assign, and MapPublicIpOnLaunch on default subnets) now activates whenever public pools exist: pool mode as before, plus nat mode when a wan pool rides alongside the transit segment. The transit pool is filtered out of IPAM — its addresses are gateway-LRP plumbing, never allocatable EIPs. Transit-only nat configs keep the disabled EIP stub. * feat(host): per-EIP ingress primitives for routed-NAT mode DetectUplinkFor parses ip route get to find the interface and source IP facing the pool gateway (re-run per ensure: WiFi/cellular uplinks move). EnsureEIPIngress steers an EIP into OVN with a /32 route via the VPC gateway LRP transit IP (src-hinted so host-local traffic still DNATs), answers ARP for the EIP with a proxy neighbor entry (L3 only, same MAC, WiFi-safe), sends gratuitous ARP, and adds per-EIP FORWARD accepts for DROP-policy hosts. RemoveEIPIngress mirrors; missing state tolerated. * feat(policy,vpcd): host EIP binder option on NATManager WithHostEIPBinder injects routed-mode host plumbing hooks. AddEIP binds after priming on both the fresh-add and idempotent-skip paths (host routes and proxy-ARP are volatile even when the OVN row survives, so reconcile re-ensures them after reboot); DeleteEIP unbinds best-effort. The next hop comes from the new gatewayPortIP helper reading the gateway LRP's stamped spinifex:gateway_ip (Networks fallback), with the ext-ID key now an exported policy const shared with the external package. vpcd selects the IGW pool by name instead of index — with two pools in nat mode the gateway allocator must stay on the transit pool — and wires the binder over host.EnsureEIPIngress/RemoveEIPIngress when a public pool is present. EnsureEIPIngress gains an uplink hint so dhcp-sourced pools (gateway unknown until lease) proxy-ARP on their bind bridge. * feat(dhcp): interface-MAC lease variant with MAC-keyed-router detection dhcp_mac = "derived" (default) | "interface" on external pools. The interface variant leases with the bind interface's own MAC — WiFi/WWAN uplinks drop frames with foreign source MACs, so derived chaddr MACs never complete DORA there. Option 61 stays the lease discriminator. UseIfaceMAC threads AllocateRequest → NATS wire → nclient4 → lease and persists through KV so restart re-acquires repeat it. Routers that key leases on MAC and ignore client-id would hand every lease the same IP; the manager detects an ACK matching the interface's own address or another client-id's live lease, releases the colliding lease, and hard-errors advising a static range instead. admin init auto-writes dhcp_mac="interface" for nat-mode public dhcp pools bound to non-bridgeable uplinks (wlan/wwan/ppp). * test(natuplink)+docs: Tier 2 EIP ingress e2e phases and public-pool docs The natuplink suite now detects a public (non-transit) pool in spinifex.toml and switches lanes: Tier-1-only configs keep the EIP-disabled and no-public-IP assertions; public-pool configs assert the EIP surface is enabled, the default subnet has MapPublicIpOnLaunch=true, instances auto-assign public IPs, and a new Phase 9 exercises the full EIP ingress lifecycle — host /32 route via the gateway LRP, proxy-ARP on the uplink, per-EIP FORWARD accepts, exempt-stamped dnat_and_snat, TCP handshake to the EIP, reconcile replay across a vpcd restart, and teardown on disassociate. Docs: vpc-networking README gains a public-pool section for routed-NAT nodes (init flags, dhcp_mac=interface behaviour, host-to-EIP caveat) and an updated mode comparison; COMMANDS.md notes nat-mode EIP support behind a public pool. * fix(setup): whitelist iptables, neigh sysctl, and arping for spinifex-vpcd Routed-NAT mode shells out to iptables for the transit masquerade and per-EIP FORWARD accepts, tunes proxy_delay, and sends gratuitous ARP for host-delivered EIPs. Without these sudoers entries vpcd crash-loops with "command not allowed" on nat-mode nodes. * fix(ovn): scope DeleteStaticRoute prefix match to the target router Every VPC router carries a 0.0.0.0/0 static route, so an unscoped cache match could grab another router's row and fail with a referential integrity violation, wedging IGW attach on multi-VPC nodes. Match only rows referenced by the target router, mirroring FindStaticRoute. Mock updated to the same semantics, with a regression test covering drift replacement across two routers. * fix(reconcile): always replay AttachIGW so host ingress state is re-ensured applyIGWs skipped AttachIGW whenever the gateway switch port existed in actual state, so the already-attached re-ensure path never ran and routed-NAT host ingress routes lost on reboot were never reinstalled. AttachIGW is idempotent; run it unconditionally. * fix(vpcd): resolve duplicate-CIDR host ingress route collisions, bootstrap VPC wins Every account's default VPC shares 172.31.0.0/16, so Tier-1 host routes collide on the single host route table and the last IGW attach silently stole the route (route replace). Pass vpcID and the gateway LRP IP through RoutedIngressHooks; the bootstrap VPC always installs its route, other VPCs only install when the CIDR is free and only remove a route their own gateway IP holds. Adds host.VPCIngressRouteVia to read the current route holder. * ci(e2e): add nightly cell 19 for routed-NAT single-node suite Cell 19 bootstraps with --external-mode=nat plus the CI static pool as the public wan pool and runs the natuplink suite, covering the Tier-1 transit datapath and Tier-2 EIP ingress. The run step exits 0 when natuplink.test is absent from the tests tar so scheduled runs against branches predating the suite stay green. * fix(admin): nat-mode init summary reflects configured public pool The summary printed 'outbound-only — no public IPs/EIPs' even when --external-pool/--external-source configured a public wan pool. Print the pool range (or dhcp bind) and note EIPs are enabled. * fix(eip,vpc): thread ctx through disabled EIP stub and NAT call sites Reconcile the routed-NAT branch with dev's ctx-first service APIs after rebase: DisabledEIPService and its tests take ctx to satisfy the EIPService interface, the vm_adapters public-IP resolver asserts the ctx-signed AssociatedPublicIPForInstance, and the default-subnet mapping test threads ctx into DescribeSubnets.	2026-07-09 09:43:32 +10:00

Josh Siviour	0823bf8c16	feat: OVN OVSDB RAFT clustering for multinode Spinifex (epic mulga-siv-486) (#458) ... * feat: add OVSDB RAFT cluster primitives to setup-ovn.sh Add --db-cluster-local-addr / --db-cluster-remote-addr flags so a management node can run the OVN NB/SB databases as a native OVSDB RAFT cluster instead of a single non-clustered ovn-central. When a local addr is given, write a shared OVN_CTL_OPTS to /etc/default/ovn-central (NB RAFT 6643 / SB RAFT 6644) and restart the per-DB units directly, since the ovn-central aggregator is ExecStart=/bin/true and won't restart its children. Empty remote addr creates the cluster (init node); a set remote addr joins it. NB/SB client set-connection runs only on the create node (RAFT replicates it cluster-wide). The single-node --management path is unchanged when no cluster addrs are supplied, so dev boxes and existing single-node clusters keep working. --ovn-remote already passes through verbatim, so a comma-separated SB endpoint list works for compute nodes; documented in usage. * feat: OVN client multi-endpoint failover for RAFT clusters Accept a comma-separated OVN NB/SB endpoint list so vpcd can target a clustered DB. config.ParseEndpoints splits the list (trimming whitespace, dropping empties); live.go Connect passes one libovsdb WithEndpoint per endpoint, so the client tries them in order, fails over on disconnect, and follows RAFT leader redirects. Single-endpoint strings still yield one endpoint, so single-node dev is unchanged. ovn-sbctl --db= already accepts the raw comma list, so the SB CLI consumers (discoverChassis, gateway_claim) need no change. * feat: write clustered OVN NB/SB endpoints across the RAFT quorum spx admin init/join now emit comma-separated OVN NB/SB endpoint lists for the first three quorum nodes (formation.BuildOVNDBAddrs) instead of loopback or a single leader address, so vpcd fails over across the cluster. firstboot defers OVN bring-up to the provisioning controller when it owns formation (SkipFormation): a standalone single-node .db would otherwise block the controller's clustered create/join. * test: add multinode OVN RAFT cluster + failover e2e; document clustered topology ovn_raft_test.go asserts NB/SB cluster/status reports a 3-server quorum with one leader on every DB node, then stops the NB leader's ovn-central and proves an NB write still lands via a surviving endpoint. Docs: vpc-networking gains the multi-endpoint vpcd config and a RAFT cluster-status debugging section; network-connections lists the 6643/6644 RAFT ports.	2026-07-09 09:43:29 +10:00

Manager MIG tests cover AddMIGInstances, Claim/Release on mdev-backed entries, MarkMIGFailed, ReclaimByMdev, and interaction with whole-GPU MarkFailed — all using fake mdev directories in t.TempDir() so no GPU hardware is required. * feat(gpu): dynamic MIG profile-per-request with on-demand GI/CI lifecycle Replaces static config-driven MIG pre-carving with a dynamic model where the MIG profile is specified per RunInstances call via mig.<profile> instance type names (e.g. mig.1g.10gb) that mirror nvidia-smi nomenclature directly. - Manager.Claim(instanceID, profileName): fast path claims a pre-carved slice; slow path dequeues a free MIG GPU, releases the lock, calls nvidia-smi mig -cgi/-cci to carve all slices, then reclaims the lock to commit and return the first slice - Manager.Release: last release on a dynamically-carved GPU calls DestroyAllInstances and returns the GPU to freeMIGGPUs, allowing a different profile on the next claim - AddMIGGPU(dev): registers a fresh MIG GPU for dynamic allocation; AddMIGInstances (restart recovery) keeps its no-destroy semantics - GenerateMIGTypes: produces mig.<profile> InstanceTypeInfo entries from gpu.ListProfiles at daemon startup; IsMIGType/MIGProfileFromType let callers inspect these names - buildGPUPool: calls ListInstances for recovery, AddMIGGPU for fresh GPUs, ListProfiles to collect MIG profile specs for type generation; removes setupMIGInstances and migProfileForDevice - GPUClaimer.Claim gains profileName param; daemonGPUClaimer, service_impl call sites, and fakeGPUClaimer all updated * fix(gpu): correct mdev parent detection and make --profile optional for mig enable enrichMdevPaths was using os.Readlink on "parent_bus_0" (a non-existent sysfs attribute) and then on ".." (a directory, not a symlink) — both would fail on real NVIDIA hardware, breaking CreateInstances and ListInstances on daemon restart recovery. Fix: read the mdev UUID's own symlink target, which always encodes the parent GPU's PCI address in its path (e.g. .../0000:01:00.0/<uuid>). Make basePath injectable in enrichMdevPaths so the fix is covered by a new set of unit tests using temp-dir symlinks (TestEnrichMdevPaths_*). Remove the MarkFlagRequired("profile") from "spx admin gpu mig enable": Phase 2 is fully dynamic — the daemon carves slices on demand at RunInstances time. Without --profile, the command just enables MIG mode and destroys any pre-carved slices so the daemon starts with a free GPU. With --profile, behaviour is unchanged (pre-carve a static pool). * chore: writeups for smci and arcee * test: add coverage for MIG exec, manager slow-path, instancetypes and admin - Add mig_exec_test.go with fake nvidia-smi harness covering Enable/Disable MIGMode, IsMIGModeEnabled, DestroyAllInstances, ListProfiles, CreateInstances, ListInstances - Extend manager_mig_test.go with slow-path Claim/Release tests using fake nvidia-smi - Add generate_test.go coverage for IsMIGType, MIGProfileFromType, GenerateMIGTypes - Add admin_test.go coverage for SetMIGProfile (create, update, idempotent, error paths) - Make mdevBasePath a var to allow sysfs injection in tests - Add json tags to GPUAttachment fields to satisfy musttag linter Diff coverage: 75.6% (threshold: 60%). * fixed gpu passthrough doc * Revert "fixed gpu passthrough doc" This reverts commit 1e20f5ab13. * feat: Added RTX 6000 GPU MIG support and fixed docs * feat: expose GPU/MIG inventory in GetNodes and GetVMs admin API Add Manager.Snapshot() for lock-safe pool inspection. Extend NodeStatusResponse with GPUs []GPUInfo (per-physical-GPU inventory with per-slice detail for MIG) and VMInfo with GPU *VMGPUInfo (model, VRAM, profile, mdev path for the attached GPU). Populate both in handleNodeStatus and handleNodeVMs via buildGPUInventory, buildPoolLookup, and resolveVMGPU helpers. * feat: surface GPU info on EC2 instance detail page (mulga-new-03) Admin users see a GPU card (model, VRAM, attachment type, MIG profile/mdev path or PCI address) populated from the GetVMs admin API. Adds formatVRAMMiB helper and VMGPUInfo/GPUInfo/GPUSliceInfo types to the frontend. * feat: GPU columns + inventory card on Nodes page (mulga-new-04) Adds GPU column to VMsTable (model/VRAM or MIG profile) and ResourceTable (alloc/total GPUs). Section 4 GPU Inventory card shows per-node GPU state with per-slice MIG drill-down. Also adds total_gpus/alloc_gpus to NodeInfo type. * feat: grouped GPU-aware instance type picker in Run Instances (mulga-new-05) Splits the flat instance type dropdown into Standard and GPU-Accelerated groups. GPU items show total VRAM alongside the type name. Selecting a GPU type surfaces an info line with GPU name and VRAM. * testing image builder scripts * fixed nvidia build script * more descriptive errors for image build script * more fixes * more fixes * fix: surface PCI address in whole-GPU VMGPUInfo and rebuild frontend dist Add PCIAddress to VMGPUInfo, populate it in resolveVMGPU for whole-GPU passthrough, and fix the instance detail page which was incorrectly showing instance type in the PCI address field. Rebuilt frontend dist to include GPU UI changes (inventory card, resource columns, GPU-aware instance type picker). * fix: improve kernel version detection in nvidia image build script Fall back to /lib/modules when /boot/vmlinuz-* is absent, and add diagnostic output to help debug kernel detection failures. * fixing nvidia image build script * fix ami name issue * correct kernel versions * another fix * image build works, added docker and nvidia toolkit for QoL * fix: add gpg * fixing amd image builder * add universe * another fix * nvm * fix docker user group issues * make rocm land where it is supposed to * fix docker groups * feat: add Ubuntu 26.04 GPU AMI catalog entries and fix build script parted detection Add ubuntu-26.04-nvidia-gpu-x86_64 and ubuntu-26.04-amd-gpu-x86_64 to AvailableImages, hosted on iso.mulgadc.com/system-ami/ with SHA256 checksums. Fix build-system-image.sh to detect parted in /usr/sbin when not on PATH. Suppress gosec false positives in DHCP manager (cancel stored in leaseLoop) and promisc ioctl (standard syscall uintptr pattern). * Updated passthrough doc regarding GPU images * fix: remove orphaned nolint directives (golangci-lint v2.12.2 no longer flags G115/G118) * chore: remove stale spinifex@192.168.3.107 directory Scripts were accidentally committed with a node hostname as the path prefix during initial testing.

tomnewton-mulga	43fa6eae59	feat: Updated GPU-Passthrough - AMD support, GPU images, /demo folder (#217) ... * feat: add GPU fields to NodeStatus and spx top nodes (mulga-996) - Add TotalGPUs/AllocGPUs to NodeStatusResponse (zero on non-GPU nodes) - Populate from gpuManager in handleNodeStatus - Show GPU (used/total) column in spx top nodes; "-" when no GPUs present * Fixed GPU passthrough and added test script * feat: always-probe GPU at startup, surface capability in NodeStatusResponse - Add gpuProbeResult struct and probeGPU() which runs at daemon startup regardless of gpu_passthrough config. Checks sysfs for GPUs, IOMMU groups, and vfio_pci module presence. - Store gpuProbe on Daemon struct; split NewDaemon into probe (always) and activate (opt-in) phases. - Populate GPUCapable, GPUPassthrough, GPUModels on NodeStatusResponse so operators can see hardware state before enabling passthrough. - Update 'spx top' GPU column: '-' = no hardware, '0/N*' = capable but passthrough not active, 'used/total' = passthrough active. * feat: SIGHUP hot-reload for GPU passthrough config (mulga-1001) - Export GenerateGPUTypes for use by the reload path - Add ResourceManager.reloadGPUTypes: mutates instanceTypes map in-place (preserves references held by instanceService) and updates NATS subscriptions without full daemon restart - Separate SIGHUP from SIGTERM/SIGINT: setupReload() listens for SIGHUP in a context-aware loop; setupShutdown no longer intercepts SIGHUP - Add reloadConfig() + applyGPUConfig(): re-reads spinifex.toml on signal, handles false→true (re-probe + activate) and true→false (refuse if instances running, otherwise deactivate) transitions * installer grub image fixes * made gpu-passthrough more user facing * vpcd fixes to set br-wan to promisc for public IP DHCP processes * fixed vpcd br-wan promisc and veth pair * ssh keygen fix * Fix: AMD GPU edge cases * script for running 8x instances on SMCI computer * fix: increase disk space on instances * feat: multi-GPU passthrough support for g7e.12xlarge (2× MI350X) - vm.VM: GPUPCIAddress string → GPUPCIAddresses []string for multi-GPU - instancetypes: add g7e.12xlarge (2 GPUs), GPUCountForType(), AMDmi350x model - instancetypes/generate: use GPUCountForType for GpuInfo.Count and TotalGpuMemoryInMiB - gpu/manager: Release() loops all pool entries for instanceID (not just first) - vm/lifecycle: loop over GPUPCIAddresses, emit gpu0/gpu1/... QEMU devices - daemon/handlers: claim N GPUs in loop for both RunInstances and StartStoppedInstance - daemon/vm_adapters: ReclaimByAddress loops GPUPCIAddresses; ReleaseGPU checks len > 0 - scripts/launch-gpu-fleet: fixed fleet — 6× g7e.4xlarge + 1× g7e.12xlarge * feat: per-instance-type disk size in GPU fleet (300 GB single, 600 GB dual) * fix: multi-gpu instance types * fix: kill QEMU synchronously when QMP handshake fails to free VFIO device When startQEMU succeeds but newQMPClientWithHandshake times out, the instance has not yet been inserted into the manager map so vmMgr.Delete in the rollback path is a no-op. QEMU keeps running and holds the VFIO group open. The GPU pool entry gets freed, the next Claim returns the same PCI address, and every subsequent QEMU fails with 'device or resource busy'. Fix: SIGKILL QEMU and wait for it to exit before returning the QMP error, ensuring the VFIO device is released before the caller recycles the GPU pool slot. * fix: quarantine GPU after QEMU launch failure to prevent re-assignment cascade When QEMU crashes during startup (e.g. pci_irq_handler assertion on a specific GPU), the pool Release frees that address and the next NATS request immediately re-claims the same broken device. Add MarkFailed() to gpu.Manager which sets Available=false for a PCI address after a launch failure, preventing re-assignment until the daemon restarts. Call MarkFailed for each GPU address in both RunInstances and StartStoppedInstance rollback paths after the Release succeeds. * fixed instance fleet launch script * remove known hosts and stagger provisioning * improvements to launch script * more upgrades * single instance gpu instance provisioning * fixed single instance provision * smci computer demo dashboard * fixes to launch script * updated smci dashboard_server * fixed demo dashboard * updated dashboard.py * feat: GPU Passthrough fixes to passthrough process - builds proper AMD or NVIDA ready images, generalised launch script * feat: gpu-passthrough updating image builder to include gpu-ready ubuntu images * fixing image builder process * fixed image builder to remove /tmp/ file before import to free space * fix: Updated COMMANDS.md to reflect new GPU management admin commands * Update docs, update internal launch script to work with new SGs, test tweaks * Updated Docs, fixed internal launch-gpu.sh script, test tweaks * fxing CI race due to GPU load	2026-05-13 11:07:13 +10:00
