Ben Duncan	42d87d7a5a	feat: EBS export tunables, plus blob-read fault isolation for ebsmetadata (#799) ... * feat(ebs): make nbdkit thread count and per-volume read cache configurable Both numbers that set a volume's export concurrency and memory were hard-coded: nbdkit ran on its own default of 16 threads per connection because no -t was ever passed, and the read cache was a 128 MiB literal in the mount path. Neither could be changed without a recompile, and neither was visible in the logs or the process argv. Add default_threads and cache_size_mb to [nodes.<node>.ebs]. Defaults are unchanged, so a config that does not set them behaves exactly as before. CacheSizeMB is a pointer so an explicit 0 (cache disabled) stays distinguishable from an unset key, matching how ViperblockConfig treats its own toggles. -efi volumes stay uncached regardless. Validation is a range check only. Both are operator tunables applied per nbdkit process, and there is one of those per volume, so the host cost is the value times the volume count -- left for the operator to weigh rather than second-guessed here. * feat(security): arm the firewall by install path and sync the clock at firstboot The host firewall armed itself from a code default, so a curl-to-bash install onto an existing Debian or Ubuntu machine applied a default-deny INPUT policy seconds after bootstrap. Anything the operator was already running that is not on the allow list stopped accepting connections, with nothing logged and no config key to set beforehand — no template writes firewall_enabled, so every install fell through to the default. Arming is now the install path's decision. setup.sh takes --firewall=on|off and records it in /etc/spinifex/firewall/mode, defaulting on under ISO_BUILD and off everywhere else: the ISO is an appliance on hardware we define, a package install is a guest on a machine that was already doing something. firewall_enabled becomes a three-state *bool so "unset" and "explicitly false" stay distinguishable. Flipping the default to false instead would have torn down a working policy on every existing node, because false is an instruction to disable rather than an absence. Resolution is config, then mode file, then on, so a node installed before any of this keeps what it has. The ISO had the opposite problem. setup.sh is the only place that enables spinifex-firewall.service and it returns before that line under ISO_BUILD, with no systemd in the chroot to talk to. Nothing else enabled it, so after a reboot the ruleset — runtime state — was gone, and ReconcileFirewall short-circuited on an unchanged peer file and never put it back. An ISO node was firewalled until its first reboot and open permanently after. firstboot now enables the unit, and the reconcile checks the table is loaded rather than treating an unchanged peer set as proof the policy is applied. Two policy changes: 443 is held for the nginx TLS edge so that rollout needs no per-node firewall change, and the SSH port is read from sshd_config and its Include drop-ins instead of being hardcoded to 22 — a host on Port 2222 was allowed exactly one port that was not the one it uses, and ct state established kept the operator's session alive until they disconnected. 53 stays open on every node, now with a comment saying so: northstar serves public authoritative DNS. Clock: firstboot steps and waits for sync before spx admin init mints credentials, since a certificate issued against a wrong RTC carries a NotBefore that outlives the correction. Bounded to 60s and non-fatal so an air-gapped install still completes, and once is enough because rtcsync writes the corrected time back. A chrony drop-in replaces Debian's makestep 1 3, which stops stepping after three updates and then slews at roughly 7 seconds a day — a node that burned those before the network came up never visibly converged. * fix(security): let a node join a cluster whose firewall is already armed Expanding a single-node ISO install into a cluster could not succeed. Two independent blockers, both from the same root: the peer set is derived from converged cluster state, but the ports needed to reach convergence are gated on that same set. The formation port is peer-scoped, and a node dialling in to join is not a peer yet, so the handshake was dropped rather than refused and the joiner retried in silence until it timed out. It cannot simply move to the public rule: outside formation the same port carries the daemon cluster manager, whose /health and /local/* routes report node topology, service inventory and running instances unauthenticated. So it is opened for the formation window only, by spx admin init, and closed again on every exit path. The reconcile then deadlocked. Holding out for the full chassis list is right on a node with no policy loaded, but on one armed for a smaller cluster the ports a joining node needs in order to register its chassis are exactly the ones the stale set blocks, so the list can never complete. Widen the peer set on the tunnel set already loaded, and report the partial state so the caller retries sooner than the steady-state interval. A converged cluster whose Southbound DB is briefly unreadable is still left untouched. * docs(install): explain the firewall around cluster formation An ISO-installed server is a cluster of one, and its firewall admits internal cluster traffic only from members it recognises. Forming a cluster out of such servers therefore needs the firewall off first: step 3 of the multi-node guide has each server dial node 1's OVN database on the raft ports, and those are peer-scoped like everything else on the cluster plane. Neither guide said so, and the failure is a silent drop that looks like a network fault. Both guides now walk the off / form / on sequence, and the multi-node guide gains a reference section covering which ports are public, how arming differs between the ISO and the binary installer, and how to verify membership landed. Re-enable the boot-time unit whenever the daemon arms the policy. Disabling the firewall to form a cluster also disables that unit, so re-arming used to look complete while leaving the node bare after its next reboot. * fix: make the ISO-to-cluster conversion path work end to end Forming a cluster from four ISO-imaged servers surfaced a run of bugs that share a starting state CI never exercises: the ISO delivers an initialized, armed, running node, while the conversion path was written against the binary installer's unconfigured one. - install-node.sh never disarmed the host firewall, so nodes 2 and 3 could not dial the first node on the OVN raft ports and formation could not proceed. It now owns the whole lifecycle: disarm, form, re-arm, then verify the loaded policy against the expected peer set. - spx admin init left the admin access key and secret empty on the preserve path. The pair cannot be read back, and the IAM store is rebuilt by formation, so the empty strings reached every joiner's bootstrap.json and crash-looped awsgw. It is reissued instead, and IAM seeding now skips an empty admin block rather than taking the gateway down on every restart. - node-reset.sh left /etc/default/ovn-central behind. Raft membership lives in that file, not in the databases the reset deletes, so ovn-central recreated the database as a cluster member dialling a peer that had itself been wiped. - node-reset.sh also destroyed the installed firewall policy, which nothing regenerates. set-peers then failed on every attempt and the node stayed open permanently and silently. The arming mode is read before the wipe and the stage regenerated after it. - spinifex-firewall-apply rejected every verb when the policy file was missing, including disable. Turning the firewall off is the recovery path, so that left a node that could be neither armed nor disarmed. - viperblock exited 0 on a fatal startup error, so Restart=on-failure never fired. During formation its JetStream bucket has no leader yet, so the EBS provider died for good and every volume request failed with no responders. predastore and qemunbd had the same bug. - spx admin images import created image directories at 0700, so the first sudo import locked group members out of a tree deliberately made group-writable. Three of these hid behind checks that cannot succeed: ovn-sbctl show against a clustered database, and the OVN northbound and southbound waits in setup-ovn.sh. All three failed to stderr and let the run continue, so a check that could never pass was indistinguishable from one that was merely slow. The USB install guide claimed the ISO leaves Spinifex unconfigured and told the operator to run spx admin init. firstboot has always done that itself, so the guide now describes what the ISO actually produces and how to start using it. * fix: let spread placement launch across every node A spread placement group reserved four distinct nodes correctly and then failed the launch with ServerInternal, having started only two or three of them. The scheduler was never at fault; two faults downstream stopped the instances following the reservation. vpcd subscribes to vpc.add-nat with QueueSubscribe, which delivers one message at a time, and the handler holds its reply across the OVN flows barrier. The 45s caller deadline was sized against a single 30s barrier, which is right for one instance and wrong for the N a spread launch issues at once — the third request waits behind two full barriers and times out. That one subscription now overlaps its handlers under a bounded semaphore. Each barrier still syncs after its own write, so the guarantee is unchanged while N barriers collapse into roughly one. With the requests overlapping, every barrier still ran to its alarm. install-node.sh computed OVN_REMOTE after building the database nodes and gave it only to compute nodes, so the database nodes were configured without --ovn-remote. setup-ovn.sh writes ovn-northd's NB/SB connections from that list and skips it on the localhost default, and it already documents what follows: a northd dialling only its local member stops advancing nb_cfg once raft leadership moves, wedging ovn-nbctl --wait=hv. The list is knowable before any node is touched, so it is computed first and passed to the database nodes too. Nothing reported an OVN fault while this was happening. Every chassis was registered, ovn-controller and IPsec were up, and the raft cluster was healthy. The only signal was the barrier logging that it had overrun and was continuing without confirmation — which reads like slowness and was a permanent wedge. * feat: sweep block sizes in the disk benchmark and add an iperf3 network benchmark * fix: use iperf 2 with CSV output and report why a remote start failed * fix: stop pkill matching its own shell and verify the iperf server is listening * ci: run the predastore throughput benchmark at the end of the nightly * ci: boot the ISO in the nightly, single-node and three-node * ci: use the existing CI node password secret in the ISO cells * ci: report free space before the benchmark instead of failing inside warp * ci: keep the benchmarks and node disks off tmpfs * ci: export the work directories from RUNNER_TEMP rather than job env * ci: run the ISO and benchmark workloads from the nvme scratch area * perf: run guest NICs on vhost-net with multiqueue Guest-to-guest VPC throughput measured 1.68 Gbit/s single-stream against 21.8 Gbit/s host-to-host on the same underlay, and did not improve with more streams. QEMU's -netdev tap defaults vhost to off, so the whole datapath ran in the main loop thread in userspace: that thread sat at 59-65% CPU while all four vCPU threads idled at ~4%. Every tap netdev now carries vhost=on, and VPC ENIs additionally run multiqueue at min(vCPUs, 8) queue pairs. Multiqueue needs all three of the tap, the netdev and the device to agree, so TapNetDev and NetDevice derive the netdev options and the 2N+2 MSI-X vector count from one queue figure rather than leaving callers to keep them in step. The QMP hot-plug path takes the same options as cold boot, with a test comparing it against the rendered cold-boot strings so the two cannot drift. MMIO machines stay single-queue: they have no MSI-X. * ci: check out the sibling repos the go workspace needs in the ISO cells * ci: skip cell-21 workload cleanup when the workload never ran * ci: size the cell-21 node at 8 GiB and keep its serial log * ci: keep the cell-21 node diagnostics alongside the serial log * fix: let the daemon open /dev/vhost-net and delete multi_queue taps Enabling vhost=on broke instance launch two ways. DevicePolicy=closed gates the cgroup device list before capabilities are consulted, so QEMU's open of /dev/vhost-net returned EPERM despite CAP_DAC_OVERRIDE; add the device to the allow list and bump the unit version. Separately, `ip tuntap del` re-opens the device with TUNSETIFF and fails with EINVAL on a multi_queue tap, leaking it on every teardown; route deletion through `ip link del`, which is flag-agnostic. * perf: default guest NICs to a single queue Multiqueue measured a net loss. Spreading one flow across queue pairs reorders packets and TCP reads that as loss: a 4-vCPU guest fell from 1.76 to 1.50 Gbit/s, with cwnd collapsing on spurious retransmits. The host overlay funnels a node pair onto one softirq core, so the extra queues have no headroom to win back what the reordering costs. Keep the plumbing and its tests behind MultiqueueNICs so re-enabling is one line once that funnel is fixed. vhost-net stays on unconditionally; it moves the datapath off the QEMU main loop, measured at 60% of a core under load against 3% with it. * fix: raise the UDP receive buffer for predastore's QUIC transport Predastore carries blob, meta and raft over QUIC and quic-go asks for a 7MiB receive buffer. Left at the kernel default of 208KiB it silently dropped datagrams under load: the four-node cluster had shed 80k-125k each, which failed shard writes, put raft into repeated elections, and ultimately handed guests an I/O error that cost two of them their root filesystems. Adds a sysctl stage writing /etc/sysctl.d/99-spinifex-net.conf, so the setting lands in the ISO image and on every node push rather than living in a runbook. * ci: give the cell-21 workload an identity the node accepts * feat: tie the guest MTU and NIC multiqueue to ipsec_enabled ESP costs 34 bytes on top of geneve's 58, so a cluster running the overlay in plaintext can advertise 1442 instead of 1408 — worth roughly 10% of guest throughput. Derive it from network.ipsec_enabled rather than hardcoding the conservative figure. Multiqueue moves with the same flag, because its sign depends on it. Behind IPsec it costs ~12%: ESP has no L4 ports, so RSS funnels a node pair onto one core and extra queues only reorder packets, which TCP reads as loss. Without IPsec the sending host's single vhost thread saturates first and queues are worth +54%. IPsec on with multiqueue on is the worst of the four combinations, so it stops being a standalone knob and becomes vm.Deps.MultiqueueNICs. The reconciler only ever created a subnet's DHCPOptions row and never revisited it, so the create-time MTU stuck for the life of the subnet and this change would have applied to new subnets only. Worse in the other direction: turning IPsec back on would have left subnets advertising 1442 over ESP, which drops large segments with no ICMP to recover from. applySubnets now diffs and updates in place. reconcile.Config takes IPSecDisabled rather than IPSecEnabled so the zero value is the conservative MTU — a caller that forgets it is merely slower. * docs: add an install-time performance tuning guide Measured on the four-node cluster rather than inferred: the UDP receive buffer sysctl, what IPsec actually costs and why, the multiqueue sign flip, the overlay MTU budget, and the jumbo-frame check that must precede enabling it. A starter doc — several sections end in an open question rather than a recommendation. * ci: keep the cell-21 node alive for the workload step * ci: collect the cell-21 qemu log and widen its timeout * feat: derive the guest MTU from the fabric, and deepen the virtio NIC config The overlay overhead is passed on to the guest rather than hidden from it. Hiding it means running the fabric far enough above 1500 that a standard guest MTU fits in the headroom, which is what the large public clouds do — but they own the switches. On a fabric we do not control, the honest figure is the one the path can carry, and a jumbo underlay should reach the guest: 9000 gives 8942, or 8908 with IPsec. network.underlay_mtu is the lever; SubnetMTU spends it. Configured rather than probed, because a node's own NIC MTU says nothing about the switch between it and its peers. host_mtu sets VIRTIO_NET_F_MTU so a guest that never takes a DHCP lease — statically addressed, or IPv6-only — still learns the ceiling. rx/tx_queue_size raise the virtio ring from QEMU's default 256. That default is a packet-rate ceiling rather than a memory saving: a vCPU preempted for a fraction of a millisecond fills all 256 slots and the overflow is dropped. ethtool is the only way to read NIC offload, ring and channel state, so a node without it cannot be diagnosed for throughput at all. * ci: give the cell-21 workload its own guest key * fix: set the guest MTU on the tap, not just in the guest The tap was created and brought up without an MTU, so it stayed at the kernel default of 1500 while DHCP and host_mtu told the guest something else. Harmless at 1442; it silently blackholed every large frame on a jumbo underlay, with no ICMP back because the drop is at the first hop. TapSpec.MTU comes from the same guest overlay MTU the DHCP option and host_mtu already use, and is applied in the bring-up call so a size the fabric cannot carry fails the launch instead of degrading quietly. * fix: stop setting tx_queue_size, which QEMU caps at 256 for tap QEMU only honours a tx_queue_size above 256 for vhost-user and vhost-vdpa backends. On a tap it rejects the value outright rather than clamping it, so every launch died with "must be a power of 2 between 256 and 256" and the instance went straight to terminated. rx_queue_size is unaffected and stays at 1024. A test pins the absence of tx_queue_size across machine types and queue counts. * docs: lead the tuning guide with the overlay segmentation finding The guide's headline was a 5.4x that came almost entirely from turning IPsec off, and it treated MTU and the fabric as the main levers. The host reaches 92.6 Gbit/s at MTU 1500 on the same NIC, so the fabric is not the constraint and the encrypted default is not the thing to tune away from. Adds the host-versus-guest comparison up front, documents network.underlay_mtu, and makes the missing segmentation offload the first open question. * ci: stop deselected matrix cells failing in teardown * docs: quantify what disabling overlay IPsec is worth The guide described the trade without the numbers an operator needs to make it. Adds the measured 4.9x, notes that the MTU and multiqueue changes follow ipsec_enabled rather than being separate knobs, and records two transition hazards: a stale wide MTU on running guests, and RunInstances failing while the OVN flows barrier catches up with the new SAs. * ci: collect and retain the e2e benchmark and cluster logs Cells 21 and 22 both copied two paths that only ever exist on the nodes, so the benchmark JSON was never uploaded and cell-22 collected nothing at all. Both now gather what they actually produce, and keep it for 90 days. * fix: quieten spx by installing an explicit CLI logger default spx never set a process logger, so it inherited whatever a linked package left behind — until now a JSON handler at Info on stdout, interleaving library log records with command output and breaking piped use. Execute() claims the default before any command runs: text on stderr, LevelError, so commands report failures through their own stderr writes and libraries stay quiet. --verbose/-v raises to info and SPX_LOG_LEVEL sets an arbitrary level, the flag winning over the environment. Service subcommands still call initTelemetry, which replaces the handler outright. No root --debug flag: viperblock, qemunbd, nats and awsgw each define their own --debug with a service-specific meaning, and a root persistent flag would shadow inconsistently depending on the command. The guard test samples the handler at package-init time rather than inside the test, because tests in this package start services that install their own logger legitimately. * feat: private /admin/CreateAccount for self-service tenant signup Add POST /admin/<Method> to the AWS gateway: SigV4-signed, JSON in and JSON out, callable only by an IAM user in the super-admin account holding spinifex:<Method>. CreateAccount is the one method, so a signup form can provision a tenant without an operator shell. No new service, port, unit or certificate — it mounts inside the gateway's existing authenticated group and inherits its auth, throttling and tracing. Provisioning is resumable rather than transactional, which fits stores that have no transaction. Two CAS creates carry the correctness: the client token admits one in-flight attempt and makes a lost response replayable for 24 hours, and the name reservation makes duplicate account names impossible. Every step after the account exists is create-if-absent, so a retry with the same token finishes the job instead of failing. The CLI and the endpoint share one provisioning helper, which closes a gap on both at once: CreateAccount never checked names, so running `spx admin account create` twice produced two accounts that differed only by ID. The response waits for the account's default VPC over a new ec2.EnsureDefaultVpc request/reply, rather than trusting the existing fire-and-forget iam.account.created publish — credentials for an account that cannot launch anything are worse than a slower call. [signup] max_accounts bounds how many accounts may exist; absent means uncapped, which is what every cluster does today. * fix: stop the awsgw template hardcoding one deployment's console URL console_url shipped as https://console.spx3.com, so every fresh install — including an on-premise cluster that will never run signup — was configured to point new accounts at our console. It is the only deployment-specific domain in any template. It now ships empty, and the gateway warns when it provisions an account without one, since a blank sign-in link is otherwise visible only to the customer who receives it. Extract the remote client from the command body while here. The signing, request shape and error decoding are the part a Cloudflare Worker mirrors, and as a function they are testable against a TLS test server rather than only by hand against a live cluster. * refactor: drop console_url from signup and default max_accounts to 128 The gateway never read console_url — it passed the value straight through to the response, and the idempotency record froze it for 24 hours so a corrected typo still replayed stale. The client that made the request already knows where it wants to send the new tenant. max_accounts is now a pointer in the parsed config so an absent [signup] section takes the 128 default while an explicit 0 still means uncapped. * feat: run the predastore fault-injection harness as cell-24 Cell-23 asks how fast predastore is when every node is healthy; cell-24 asks whether it survives one that is not. It runs after cell-23 rather than beside it: both want a quiet single runner, and a benchmark sharing a machine with a fault injection run measures the wrong thing. The port offset keeps the two clear of each other even so, and the job clears stale nodes on entry and exit, since a run killed before its cleanup trap leaves one holding ports that fail the next run somewhere unrelated. * ci: keep the throughput benchmark's output with its results The run log only existed in the job log, so the artifact it uploaded could not be read without going back to the run that produced it. * ci: keep the fault-injection run log with its results events.txt carries the timeline and the FAIL line, but not the build output or anything Warp wrote before the harness took over, so a failed cell could only be read from the job log it was printed into. * fix: serve the cluster region to the console instead of hardcoding it The console hardcoded ap-southeast-2 as its SigV4 region in seven files, so on any other cluster the credential scope was wrong and the gateway rejected every signed request. The SPA is embedded in the binary, so a build-time value would pin one binary to one region. The UI server now serves GET /api/config with the region, no-store so a proxy fronting several clusters cannot serve one the other's region, and the SPA loads it once before render. The region comes from the serving node's config because awsgw pins signature verification to that same field. Reading the cluster-wide [aws] region instead would let a cluster whose two keys disagree pass review and still fail to authenticate. Also relabels the login card as Spinifex credentials, since the fields are not AWS ones, and hides the CA install banner unless the console is reached directly: behind a proxy with a publicly trusted certificate there is nothing for the cluster CA to fix. * fix: say once when the host firewall will not be maintained Both quiet outcomes of the reconcile — no cluster config, and the policy switched off — return nil without logging, so a node that never arms is indistinguishable in the journal from one that armed on its first pass. * test: arm the host firewall before asserting on its peer set Only the ISO install arms the policy; every other path writes off to the mode file, so the daemon disables the firewall and never writes a peer set. The test read that file as its baseline, which it could never have. It now switches the mode on for its own duration and puts it back, waits for the peer set the way install-node.sh does, and on failure reports the mode, the node count and what the daemon said rather than just the missing file. * test: move the console region test to the external cmd package It was in package cmd, which test-package-check rejects, so preflight failed on the branch. The hook follows the pattern already in export_test.go. * test: make the reboot EIP diagnostic capable of naming the drop The two ofproto/trace probes injected packets with no TTL, so OVN's router killed them at lr_in_ip_input and both traces ended early for a reason that had nothing to do with the failure under investigation. A keyword filter then stripped the table-match lines, hiding where each trace stopped. Traces now carry a TTL and are kept whole, the real datapath megaflows for the guest reply are dumped alongside them, and any drop matching the guest source is resolved from its OpenFlow cookie back to the Southbound logical flow that installed it. * fix: exempt an EIP instance from the subnet drop gate with allow, not reroute A subnet with no route of its own carries a priority-1100 drop policy, and an instance with an external IP is lifted above it by a priority-1200 policy. That policy rerouted to the pool gateway, which in distributed NAT is outside every logical router port subnet, because the gateway LRP is the link-local /30. The static default route survives that by naming an output port; a routing policy has no such field, so ovn-northd discarded all three of them and the drop gate below swallowed everything the instances sent. The effect was that every external IP answered inbound traffic and none of it came back: the SYN reached the guest, the guest replied, and the reply died in the router's policy stage. Guest-initiated egress was lost the same way. The policy only ever needed to lift the gate. The router's default route already points at the gateway, so allow leaves the routing decision intact and gives northd nothing to reject. * test: match the log the firewall quorum gate actually emits The assertion waited for "chassis encap addresses; not writing a partial peer set", which no code has ever logged. The reconcile reports a short chassis list as "OVN reports N of M chassis encap addresses" and the maintain loop carries that into its retry warning, so the wait could only ever time out. Arming the node in the previous commit got the test as far as this assertion for the first time, which is why it surfaced now. The failure also prints the journal tail and the same inputs the earlier wait reports. * fix: stop one unreadable volume document failing every volume listing A single volume document whose shards no longer reconstruct made DescribeVolumes, DescribeVolumeStatus and DescribeVolumesModifications fail for every account, because the listing returned the first fetch error rather than skipping the document. ListVolumes now skips a document it cannot read or decode and logs the skip, mirroring ListAMIs. Callers whose answer would be wrong rather than merely partial take ListVolumesStrict: the orphan scan and the snapshot in-use check both gate destructive work on a complete list. The tolerance covers fetch failures as well as decode failures. An object whose shards no longer join is as unusable as one whose bytes will not parse, and it was the fetch path that took the cluster down.	2026-08-15 14:22:49 -05:00

Josh Siviour	dad5d702e1	fix: stop lbagent heartbeats on positive LB deletion, and actually enable the JetStream watchdog (#643) ... * fix(lbagent): stop heartbeating a load balancer once it is confirmed deleted A LoadBalancerNotFound response is the gateway's positive confirmation that the store has no record for the LB, not a connectivity failure — unlike a dial error, timeout, or 5xx, which leave its existence unknown and must keep retrying. Past the startup registration grace window (or after any prior successful heartbeat), it can no longer be the record's own replication race, so the agent now stops rather than retrying forever and filling the log with heartbeat noise after teardown. * fix(nats): enable the JetStream ENOSPC-latch watchdog timer nats-server disables JetStream process-wide on ENOSPC (server/jetstream.go handleOutOfSpace -> ShutdownJetStream) and never re-enables it itself — that decision is nats-server's own internal state, not spinifex's, so a restart is the only way back. The spinifex-nats-watchdog.timer + service already probe /healthz?js-enabled-only=true and try-restart on a sustained failure, but the timer's WantedBy=timers.target never took effect: neither setup.sh nor firstboot enabled it, so the watchdog shipped inert and a full disk needed a manual restart forever. Enable --now it alongside the rest of the unit set.	2026-08-02 08:21:46 +10:00
Julian Sommer	1d55404a73	revert: host DNS setup on resolved/resolvconf hosts (#580) ... This reverts commit f9c9f0b38d. #580 switched setup.sh to read the northstar :53 listener and zones from northstar.toml, so the resolved stage now defers at install time (before formation) and must be re-run afterward. Only firstboot re-runs it; the manual setup.sh + spx admin init install and CI never do, so those hosts get no host DNS and cluster-zone names (ELB/EKS) fail to resolve from the node. Reverting restores the pre-#580 behaviour: systemd-resolved is configured at install time from the WAN IP, with no post-formation re-run needed. This reintroduces the original gap where resolvconf hosts get no host DNS. The proper fix configures host DNS from spx admin init/join for both resolver managers (mulga-x30yv).	2026-07-23 11:23:21 +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
joshsiv-mulga	fba2103133	feat(firstboot): SkipFormation flag — bm-bootstrap owns cluster formation ... Add SkipFormation bool to firstboot.Config. When set, the cluster formation block (spx admin init/join) is replaced with a no-op echo, leaving formation to the provisioning controller. Wired through: autoinstall reads SPINIFEX_SKIP_FORMATION=1 from env, install.go passes it to firstboot.Config. spinifex-init.sh parses the kernel cmdline param and exports it. boot-handler.go hardcodes SPINIFEX_SKIP_FORMATION=1 so all bare-metal CI nodes skip formation — bm-bootstrap.sh always runs spx admin init/join with the correct --nodes N from nodes.json, enabling proper multi-node formation.	2026-05-14 16:57:54 +10:00
joshsiv-mulga	5f8ee0b5a2	feat(installer): persist SPINIFEX_INSTALL_CALLBACK through firstboot reboot ... In the PXE path SPINIFEX_INSTALL_CALLBACK arrives on the iPXE kernel cmdline but was never threaded into the firstboot script, so firstboot never curled the controller's /done endpoint. The flag stayed on disk, the node re-entered the install loop on the next PXE boot. Fix: read SPINIFEX_INSTALL_CALLBACK from the live-environment env in toFirstbootConfig and embed a best-effort curl into the generated firstboot script, fired once after the success marker is written. Interactive and USB-stick installs are unaffected (env var absent -> callbackBlock is empty, no curl injected).	2026-05-07 12:28:09 +10:00
tomnewton-mulga	28ca689130	feat: VFIO GPU passthrough (#188) ... * feat: add GPU discovery package (mulga-992) Adds spinifex/gpu package with sysfs-based GPU enumeration, IOMMU group member lookup, and a PCI device ID model table. Vendor-specific enrichment via nvidia-smi is attempted opportunistically and falls back to the built-in table when unavailable. All discovery and IOMMU logic is covered by unit tests using mock sysfs trees. * feat: add VFIO bind/unbind and GPU pool manager (mulga-993) Adds gpu.BindVFIO/UnbindVFIO using sysfs driver_override for per-device driver switching, and gpu.Manager which owns the claim/release lifecycle for the GPU pool including full IOMMU group binding, rollback on partial failure, and marking entries unavailable when rebind fails after VM termination. * feat: add G5 instance type generator with GPU model support (mulga-994) - Add GPUModel type, NVIDIAa10g constant, and GPUModelForVendorDevice lookup - Add generateGPUTypes to emit g5.* types with GpuInfo populated - Add IsGPUType helper for consumers filtering GPU-capable types - Update DetectAndGenerate to accept gpuModels []GPUModel parameter * feat: integrate GPU passthrough into daemon lifecycle (mulga-995) - Add gpu_passthrough config flag; discover GPUs and build manager at startup - Gate g5 instance types on GPU pool availability via canAllocateCount - Claim GPU (VFIO bind) in LaunchInstance; inject vfio-pci QEMU device - Release GPU (VFIO unbind, rebind to host driver) in stopInstance - Re-claim GPU on daemon restart when QEMU process is still alive - Add UseUEFI / OVMF support for x86_64 VMs (optional, falls back to SeaBIOS) - Fix Claim to use stored OriginalDriver when device is already vfio-pci bound * 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 * feat: Ubuntu 24.04 GPU AMI build pipeline (mulga-997) Extends build-system-image.sh to support Ubuntu alongside Alpine. Key differences handled: partition table (parted resizepart p1), bind mounts for DKMS (/proc /sys /dev), apt vs apk, systemctl vs rc-update. DISTRO defaults to "alpine" for backward compatibility. Adds ubuntu-gpu.conf manifest and ubuntu-gpu-setup.sh chroot script that installs nvidia-headless-550-server with DKMS pre-built against a pinned linux-image-generic kernel, blacklists nouveau, and prevents unattended-upgrades from invalidating the pre-built module. * 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 * feat: spx admin gpu status/enable/disable commands (mulga-1000) - admin.SetGPUPassthrough: Go implementation of the idempotent TOML write (replaces the inline Python heredoc in spx-test-gpu.sh) - spx admin gpu status: shows GPU hardware, IOMMU/vfio state, passthrough activation, and advertised g5 instance types via NATS NodeStatusResponse - spx admin gpu enable: checks prerequisites, writes TOML, sends SIGHUP, polls until daemon confirms GPUPassthrough=true - spx admin gpu disable: refuses while GPU instances are running, otherwise writes TOML, sends SIGHUP, polls until confirmed - spx-test-gpu.sh: replace Python TOML heredoc with spx admin gpu enable * fixed admin * fix: filter Intel iGPU from passthrough pool, use lspci for consumer GPU names Discover() now skips non-NVIDIA/AMD vendors so Intel iGPUs never enter the passthrough pool. enrichFromLspci() uses the system PCI ID database via lspci -vmm to populate the model name for any card not in the hardcoded table, without needing nvidia-smi or driver tools. * fix: grant CAP_SYS_ADMIN and vfio device access to spinifex-daemon GPU passthrough requires writing to /sys/bus/pci/drivers/vfio-pci/unbind on instance stop. The kernel gates this on CAP_SYS_ADMIN regardless of file permissions. QEMU subprocesses also need char-vfio rw access to open /dev/vfio/N for the passed-through device. * fixing gpu bining permissions * working state of gpu passthrough on phyiscal box * installer grub image fixes * made gpu-passthrough more user facing * fixed banner * fixed banner * banner fix * gpu passthrough docs * preflight tweak * vpcd fixes to set br-wan to promisc for public IP DHCP processes * fixed vpcd br-wan promisc and veth pair * ssh keygen fix * fixes after running /review-branch * feat: re-wire GPU claim and device injection after vm.Manager refactor GPU passthrough claim (VFIO bind) and QEMU device injection were lost when dev's vm.Manager refactor (#185/#186) moved StartInstance/ CreateQMPClient into vm/lifecycle.go. Re-add both in their correct new homes: - daemon_handlers_instance.go: claim GPU before vmMgr.Run() in both RunInstances and StartStoppedInstance handlers; release on failure - vm/lifecycle.go startQEMU(): inject vfio-pci device with x-vga flag derived from instance.GPUXVGAEnabled when GPUPCIAddress is set * fix: Create spinifex user ~/.ssh and keys in firstboot --------- Co-authored-by: Ben Duncan <5178243+benduncan@users.noreply.github.com> Co-authored-by: Julian Sommer <115516918+juliansommer@users.noreply.github.com>	2026-05-06 09:52:23 +10:00

tomnewton-mulga	054485e930	refactor: move systemd unit files into installer/systemd package ... Extract all inline systemd unit and drop-in content from install.go and firstboot.go into a dedicated cmd/installer/systemd package for editability. Bash scripts remain inline in firstboot.go. Also copies the GRUB splash image from the live ISO into the installed system's /boot/grub/ and sets GRUB_BACKGROUND so the branded background appears in the post-install GRUB, not just the installer GRUB.	2026-04-15 15:34:40 +10:00
tomnewton-mulga	24429ee8b5	fix: simplify firstboot — delegate setup to setup.sh with embedded tarball ... Remove the duplicated chown/ownership/symlink block from the firstboot script. setup.sh (called with INSTALL_SPINIFEX_TARBALL) already handles service users, directory ownership, sudoers, systemd unit installation, and enabling spinifex.target — the same steps as the online curl|bash install. Firstboot now follows the documented install flow directly: 1. setup.sh --tarball (air-gapped equivalent of curl|bash) 2. setup-ovn.sh --management 3. spx admin init 4. systemctl start spinifex.target Also reduce wait-for-nats.sh timeout from 90s to 30s per reviewer feedback.	2026-04-15 13:36:07 +10:00
tomnewton-mulga	69c8b20b78	fix: harden ISO installer error handling and safety checks ... - partUUID: error on empty blkid output instead of writing UUID= to fstab - installBootloader: fail if both EFI and BIOS targets fail; track efiErr - machine-id fallback: write at mode 0600 so systemd can commit on first boot - Run: defer unmount so partitions are always cleaned up on failure - copyRootfs: verify critical paths exist after rsync before continuing - resolveNIC: skip virtual/bridge interfaces (docker0, virbr0, ovs-system) - EjectAndReboot: use syscall.Reboot instead of exec(reboot) which needs D-Bus - ui.Run: return error on TTY open failure instead of silent fallback - firstboot script: trap EXIT to always self-disable, preventing retry loops - enableUnit/enableBannerUnit: deduplicate into enableSystemdUnit; check Remove - runAdminBanner: promote service restart failure to slog.Error - parseNodeConf: log non-ENOENT read failures	2026-04-15 10:59:51 +10:00
tomnewton-mulga	02aba39942	feat: spinifex login user, credential handoff, networking hardening (ISO) ... - Add spinifex login user password via chpasswd in install.go (same password as root, collected once in TUI) - Copy /root/.aws/ to /home/spinifex/.aws/ in firstboot so the operator can use the AWS CLI without sudo after first boot - Fix getty drop-ins to be instance-specific (tty1/ttyS0 only), leaving tty2+ immediately available as rescue terminals - Remove autologin — node now requires password at login prompt - Pre-start OVS/OVN in firstboot and poll NB DB up to 120s to eliminate setup-ovn.sh timeout races on slow physical hardware - Tighten per-service ownership in firstboot (each service user owns only its own /var/lib/spinifex subdirectory) - Add LAN bridge as a non-critical systemd unit so a missing LAN cable can never stall network-online.target or firstboot - Write dhcpcd.conf with short br-lan timeout; add networking.service drop-in to treat exit 1 as success for optional interface failures - Disable IPv6 on management bridges to silence dhcpcd journal noise - Fix WAN/LAN enter-key and ESC navigation logic in TUI - Fix LAN NIC cursor to skip WAN NIC correctly	2026-04-13 12:53:07 +10:00
tomnewton-mulga	c5b6beb006	feat: multi-NIC WAN/LAN bridge network setup in ISO installer (mulga-897) ... - Replace single network screen with separate WAN and LAN screens - WAN/LAN IPs now live on Linux bridges (br-wan, br-lan) over the physical NICs, not on the NICs directly — makes OVS/OVN veth attachment SSH-safe - Add DHCP/static toggle on both screens (DHCP is the default) - Add DNS nameserver input for static mode (comma-separated, default hint 1.1.1.1 / 8.8.8.8 shown as placeholder) - Detect WiFi NICs via /sys/class/net/<name>/wireless; show SSID and password fields when a WiFi adapter is selected - LAN screen shows WAN NIC greyed/unavailable; cursor skips over it - LAN screen only shown when 2+ NICs are detected - Geneve encap IP uses br-lan address when LAN NIC present, else br-wan - Remove --macvlan/--wan-iface from firstboot; setup-ovn.sh auto-detects br-wan as a Linux bridge and uses veth mode - Pin both WAN and LAN NIC names to MAC via a single udev rules file - node.conf writes MANAGEMENT_IFACE=br-wan (bridge, not physical NIC)	2026-04-10 10:02:16 +10:00
tomnewton-mulga	03601ca89b	fix: banner service ordering, getty wait, motd append (mulga-866) ... - banner runs After=spinifex.target so services are settled before banner writes - switch systemctl restart → try-restart (safe if target not yet active) - append banner to /etc/motd with sentinel instead of overwriting, preserving the Debian disclaimer; sentinel ensures re-runs replace cleanly - remove /etc/issue write — getty shows it pre-login which is wrong - add getty@.service.d drop-in so all getty instances wait for banner before showing login prompt; prevents service messages scrolling during login - fix Makefile to prefer locally built spx/installer binaries over system PATH	2026-04-09 15:40:26 +10:00
tomnewton-mulga	cbb3e91ada	feat: add spx admin banner --boot-check, replace bash banner script (mulga-866) ... - add `spx admin banner --boot-check` subcommand to spx CLI - reads management IP from the NIC at runtime (not from node.conf) - if IP has changed, updates /etc/spinifex/node.conf and restarts spinifex.target - writes banner to /etc/issue (pre-login console) and /etc/motd (SSH MOTD) - banner instructs user to cat ~/.aws/credentials (standard AWS CLI location) - update firstboot.go to use spx-based banner unit; remove writeBannerScript and old spinifex-banner.sh entirely - new banner unit runs Before=spinifex.target so IP is current before services start	2026-04-09 14:39:56 +10:00
tomnewton-mulga	10a2a8116f	fix: resolve firstboot service failures and improve installer UX (mulga-859) ... - chown /etc/spinifex and /var/lib/spinifex to spinifex:spinifex after spx admin init so services running as the spinifex user can read configs - add Environment=HOME=/root to firstboot unit to suppress $HOME warning - increase wait-for-nats.sh timeout from 30s to 90s for slow startup - banner now writes to both /dev/tty1 and /etc/motd (visible over SSH) - add systemd.show_status=1 to GRUB cmdline for per-service boot feedback - add --removable to grub-install EFI so fallback path EFI/BOOT/BOOTX64.EFI is written (required for UTM and bare metal without NVRAM boot entries) - add root password screen and manual NIC entry to installer TUI - tee spx admin init output to /root/spinifex-credentials.txt with 0600 perms	2026-04-09 13:52:31 +10:00
tomnewton-mulga	1b39439cb8	feat: scaffold ISO installer TUI and install pipeline (mulga-859) ... Adds cmd/installer with three packages: - ui: huh-based TUI collecting disk, network, node, and cluster config - install: sequential install steps (partition, debootstrap, chroot, bootloader) - firstboot: oneshot systemd service that runs setup-ovn and spx admin init/join on first real boot Supports both single-node init and multi-node join flows.	2026-04-07 15:50:40 +10:00
