It does not sign any Docker Hub image. The `*` wildcard fallback also uses this key so unknown registries require the most restrictive path. +- **Dockerhub key = public Docker Hub** — a separate `cosign-dockerhub.pub` is used for `docker.io/parachutes/*` and the dockerhub-hosted infrastructure images that require signature verification (e.g. the `parachutes/sek8s` attestation proxy image). +- **No structural change to `CosignRegistryConfig`** — the existing `public_key: Path` field per registry entry already supports arbitrary key paths. The change is purely to the values in `cosign-registries.json.j2`, not the data model. +- **`AdmissionConfig` gains one new field** — `chutes_cosign_dockerhub_public_key_path` mirrors the existing `chutes_cosign_public_key_path`. Both are needed because `_require_ctx_key` in the chutes namespace must validate that each image's configured key is one of the two known trusted keys, not any arbitrary key. +- **`_require_ctx_key` generalised to a key set** — the `ValidationContext.required_key_path: Optional[Path]` field becomes `required_key_paths: set[Path]`. The rule passes when the configured key for an image is a member of that set. This preserves the defence-in-depth check (no image can sneak through with a weaker or unknown key) while supporting two legitimate keys for the chutes namespace. +- **`ImageManager` unchanged** — `ImageManager._pull_image()` already restricts pulls to `localregistry.chutes.ai:30500` and uses `cosign_key_path` (the private key) exclusively.

Debug builds use `audit deny` for kernel audit logging; production builds use silent `deny`. +- AppArmor abstraction `sek8s-secrets-deny`: denies shell/interpreter access to boot secrets (`/run/chutes/`), containerd socket, k3s token, and miner credentials. +- AppArmor profile `sek8s.system-manager`: named profile applied via systemd `AppArmorProfile=` — grants cache rw, credential read, containerd socket, and network access. +- AppArmor profile `sek8s.setup-cache`: named profile for the setup-cache service — grants cache rw and coreutils, no network or credentials. +- AppArmor profile `sek8s.deny-sensitive-default`: auto-attaches to common shells, interpreters, and data-transfer tools (bash, dash, sh, cat, cp, tar, rsync, curl, wget, perl, etc.) — includes both deny abstractions to block access to protected paths. +- `verify-apparmor-profiles.service`: oneshot that verifies all sek8s AppArmor profiles are loaded in enforce mode at boot. Powers off the VM on failure. +- RTMR3 progress logging: per-directory collection progress and periodic hashing progress (every 200 files) logged to `/dev/kmsg` during the expanded measurement phase. ### Changed - Split cosign signature verification into two keys: `chutes.pub` for the private localregistry (and wildcard fallback), `dockerhub.pub` for Docker Hub `parachutes/*` images @@ -25,6 +33,10 @@ Version source of truth: `ansible/guest/VERSION` - `fetch_key_and_unlock` (initramfs, init-premount): now parses `vm_auth_ss58` from the boot attestation API response and saves it to `/run/chutes/validator-ss58` (mode 600). Boot fails with poweroff if the field is absent from the response. - `proxy-manifests.yaml.j2`: removed the baked-in `validator-auth` Secret definition (it contained a hard-coded validator hotkey and is in the RTMR3-measured manifests directory). The Secret is now created at runtime by `03-k3s-validator-auth.sh`. The RBAC `secret-reader` Role updated to include `validator-auth` in `resourceNames`. The `wait-for-credentials` init container now also waits for the `validator-auth` Secret before the attestation-proxy pod starts. - `system-manager.env.j2`: removed `ALLOWED_VALIDATORS` (now in unmeasured `validator-auth.env`). `IMAGE_PULL_ALLOWED_REGISTRIES` updated to use static `localregistry.chutes.ai` hostname. `system-manager.env` is now fully deterministic at build time and safe to include in RTMR3 measurement. +- `tdx-measure-miner.conf`: added three-tier RTMR3 measurement expansion — Tier 1 (custom binaries in `/usr/local/{bin,sbin}`), Tier 2 (code injection config paths), Tier 3 (system binaries in `/usr/bin`, `/usr/sbin`, and custom shared libs in `/usr/local/lib`). Also added service configs, AppArmor profiles, and systemd units not previously measured. +- `tdx-measure-miner.conf`: removed `/etc/rancher/k3s/registries.yaml` (runtime-modified by `process-config.py`, persists across reboots; security properties independently measured through other files). +- `pods.rego`: added `MAC_ADMIN` and `MAC_OVERRIDE` to `dangerous_capabilities` to prevent containers from modifying AppArmor profiles. +- `chutes-miner-vm.yml`: inserted `apparmor-hardening` role after `cache-volume` and before dynamic config services. ### Removed - Hard-coded validator SS58 (`5Dt7HZ7Zpw4DppPxFM7Ke3Cm7sDAWhsZXmM5ZAmE7dSVJbcQ`) removed from all Ansible role defaults (`common`, `admission-controller`, `attestation-service`, `system-manager`) and inventory files (`ansible/guest/inventory.yml`, `local/inventory.prod.yml`).

A dedicated key has its own rotation cadence (very rare, requires image rebuild) and can be stored in an HSM. The Helm key is a leaf key that may rotate independently. +- **PGP (not Ed25519 or X.509)**: GPG tooling is already present on the image for Helm `--verify --keyring`. `gpgv` is a minimal verifier with no keyring management overhead — ideal for initramfs. No new crypto tooling required. +- **Root key path: `/etc/chutes/root-signing-key.gpg`**: The `/etc/chutes` directory is already measured into RTMR3 via `tdx-measure-miner.conf`. Adding a file here requires no measurement config changes for the root key itself. +- **Dynamic keys stored in `/run/chutes/signing-keys/`**: Consistent with the validator auth pattern (`/run/chutes/validator-auth.env`). Tmpfs, fully ephemeral, cleared on reboot. Not measured in RTMR3 — trust is proven via the PGP signature chain, not direct measurement. +- **Cosign keys removed from RTMR3 measurement**: `/etc/admission-controller/cosign` is removed from `tdx-measure-miner.conf`. The directory may still exist (for structure) but contains no keys at runtime. Trust in the keys is delegated to the PGP chain: RTMR3 attests root pubkey → root pubkey verifies PGP sig → PGP sig authenticates cosign key. +- **Helm key stored outside `/etc/chutes/`**: The dynamic Helm key must NOT be written to `/etc/chutes/` because that directory is recursively measured in RTMR3. Writing a dynamic file there would make RTMR3 non-deterministic. It goes to `/run/chutes/signing-keys/helm-pubkey.gpg` instead. +- **Build-time Helm install still uses a static key**: At image build time, the Helm chart is installed with a static key (the current `helm_chart_public_key_path`). This key is only needed during the build — at boot, `04-helm-chart-upgrade.sh` uses the dynamically-fetched key from `/run/chutes/signing-keys/`. The build-time key does not need to be baked into the final image. +- **Fetch in initramfs init-bottom (not systemd service or cluster-init)**: Init-bottom scripts run after the root filesystem is mounted and after `fetch_key_and_unlock` (init-premount) has established network connectivity. This ensures keys are available before any userspace service starts. The initramfs itself is covered by RTMR1, so the fetch and verification logic cannot be tampered with without changing RTMR1. +- **Fatal failure on verification failure**: If any PGP signature fails verification, the VM powers off — same pattern as `rtmr3-measure`. This is fail-closed by design. +- **API serves a JSON key bundle**: A single `GET` request returns all keys and their detached PGP signatures as base64-encoded strings. This minimizes boot-time network calls and allows atomic key set updates. +- **Multiple keys for rotation overlap**: The API can serve 2–3 cosign keys simultaneously to support VMs that haven't rebooted during a rotation window. The initramfs script fetches all keys in the bundle and installs them. + +--- + +## API Changes + +- **New endpoint**: `GET /servers/signing-keys` (public, no auth required — keys are public) +- **Response schema**: + +```json +{ + "version": 1, + "keys": { + "cosign/chutes.pub": "", + "cosign/dockerhub.pub": "", + "helm-pubkey.gpg": "" + }, + "signatures": { + "cosign/chutes.pub": "", + "cosign/dockerhub.pub": "", + "helm-pubkey.gpg": "" + } +} +``` + +- **Schema changes**: None to existing services. The new endpoint lives on the validator API (`api.chutes.ai`). +- **URL derivation**: The initramfs `fetch-signing-keys` script reads the URL from `/etc/chutes/signing-keys.conf` (set at build time to `$VALIDATOR_BASE_URL/servers/signing-keys` by the `signing-keys` Ansible role). +- **Migrations**: None. + +--- + +## Goal + +Success = Cosign and Helm keys are fetched dynamically at boot, verified against an attested root PGP key, and used for admission control and chart provenance — without baking the leaf keys into the image. Specifically: + +1. A VM boots, fetches the key bundle from the API, verifies all PGP signatures against the root key at `/etc/chutes/root-signing-key.gpg`, and writes verified keys to `/run/chutes/signing-keys/`. +2. The admission controller starts and reads cosign keys from `/run/chutes/signing-keys/cosign/` — image admission works identically to the static-key behavior. +3. `04-helm-chart-upgrade.sh` reads the Helm keyring from `/run/chutes/signing-keys/helm-pubkey.gpg` — chart provenance verification works identically. +4. A key rotation (new cosign key signed with root PGP key, published to API) is picked up by VMs on next reboot with zero image changes. +5. A tampered key bundle (invalid PGP signature) causes the VM to power off during initramfs — fail closed. +6. RTMR3 does not change when cosign or Helm keys are rotated — only the root signing key (which rarely rotates) is measured. +7. A third-party verifier can reproduce the trust chain: RTMR3 quote → root PGP pubkey hash → PGP signature on cosign key → cosign key identity. +8. All existing tests continue to pass with updated default key paths. + +--- + +## Constraints + +- The root signing PGP private key must be stored offline or in an HSM. It is never present on any VM or in any hot-path service. It is used only when rotating cosign/Helm keys (an infrequent, manual operation). +- The root signing PGP public key must be present at `root_signing_key_path` on the build machine at Ansible build time. Missing key is a hard build failure. +- The initramfs `fetch-signing-keys` script must use only tools available in initramfs: `sh`, `curl`, `gpgv`, `jq`, `base64`, `mkdir`, `chmod`. All must be copied into the initramfs via the hook. +- `curl` and `jq` are already pulled into the initramfs by the existing `fetch_key_and_unlock` hook. `gpgv` and `base64` need to be added. +- The fetch script must complete within 30 seconds (matching `TDX_TIMEOUT` from `fetch_key_and_unlock`). Network is already established by `fetch_key_and_unlock` (init-premount). +- Dynamic keys go to `/run/chutes/signing-keys/` only — never to the root filesystem, never to a measured path. +- The `/etc/chutes/` directory must not contain any dynamic files. Static build-time files (root signing key, chart-versions, chart-configs) remain there and are measured in RTMR3. +- The `admission-controller.env` file (measured in RTMR3) must reference the new `/run/chutes/signing-keys/cosign/` paths. This is a one-time RTMR3 change at the time this feature ships. +- `cosign-registries.json` (measured in RTMR3) must also reference the new paths — same one-time change. +- Do not modify `ImageConfig.cosign_public_key_path` or `ImageManager` — the system-manager images router uses a separate cosign key path for image pull verification. +- The API endpoint must be reachable from inside the TDX VM at boot time (HTTPS, public internet, same as `VALIDATOR_BASE_URL`). +- AppArmor profiles for `sek8s.system-manager` and any admission-controller confinement must allow reads from `/run/chutes/signing-keys/`. + +--- + +## Output Format + +### Ansible: New files + +1. **`ansible/guest/roles/signing-keys/tasks/main.yml`** (new role) — installs root signing PGP public key to `/etc/chutes/root-signing-key.gpg`, creates `/etc/chutes/signing-keys.conf` with the API URL, installs the initramfs hook and init-bottom script. + +2. **`ansible/guest/roles/signing-keys/files/initramfs/fetch-signing-keys`** — init-bottom script that fetches the key bundle from the API, verifies PGP signatures with `gpgv`, writes verified keys to `/run/chutes/signing-keys/`, and powers off on any failure. + +3. **`ansible/guest/roles/signing-keys/files/initramfs/fetch-signing-keys-hook`** — initramfs hook that copies `gpgv`, `base64`, the root signing key, and `signing-keys.conf` into the initramfs. + +4. **`ansible/guest/roles/signing-keys/defaults/main.yml`** — default variables: `root_signing_key_path`, `signing_keys_api_url`. + +### Ansible: Modified files + +5. **`ansible/guest/roles/admission-controller/tasks/configure-cosign.yml`** — remove the two `copy` tasks that bake `chutes.pub` and `dockerhub.pub` into `/etc/admission-controller/cosign/`.

QEMU generates the guest ACPI tables measured into RTMR0, so a different QEMU attests with an unbaselined RTMR0; tying it to the OS also enforces hosts run the release's security-patched build. Proactive operator check, not a security boundary — the real gate is the control-plane RTMR0 match. + - **Topology hard-match** in `detect_profile`: each `GpuProfile` declares `baselined_measurements`, a map of `QEMU version → set of host topology fingerprints` (`detection.host_topology_fingerprint`) with a registered RTMR0 measurement (RTMR0 = f(topology, QEMU), so a measurement is only valid for a specific topology×QEMU pair). `baselined_topologies` derives from it as the union across QEMU versions. Fingerprints are self-documenting value types in the new `chutes.guest.gpu.topology` module (see below): `NumaTopology(gpu_nodes, nvswitch_nodes, ib_nodes)` on the 2-node NUMA path (where each device→NUMA vector drives the guest PXB-PCIe grouping and thus RTMR0) or `FlatTopology(gpu_count, nvswitch_count, ib_count)` otherwise. The launch-time hard-match is deliberately QEMU-agnostic (uses the union): a host whose live topology isn't characterized at all is refused with "run discover-profile.sh and send the output." Populated for H200 / B200 / B200_XEON6 / RTX_PRO_6000 to mirror the authoritative chutes-ops `teeMeasurements` v1.3.1 (`values/chutes-api/values.yaml`). An empty map (e.g. B300, not yet characterized in sek8s) skips the launch check; verify-host will advise on such hosts since it can't confirm the measurement. +- **`chutes.guest.gpu.topology` module** — `NumaTopology` / `FlatTopology` frozen dataclasses that name every field of a topology fingerprint (per-device host-NUMA vectors vs device counts), replacing the previous opaque positional tuples (`("numa", …)` / `("flat", …)`). They are hashable value types, so they live in the `baselined_measurements` sets and support `fingerprint in baselined_topologies`; a `NumaTopology` never equals a `FlatTopology`, which is the guest-NUMA-path vs flat-fallback discriminator the string tag used to carry. Only *device* topology is captured — CPU/socket/RAM are pinned to profile constants and identical across a profile's hosts, so a host that differs only in NUMA-node count (the RTX 4-node case) or logical-CPU count is characterized by its topology, not named after the host. +- **`chutes.guest.verify` — standalone host-readiness check** (`verify-host` CLI, mirrors `run-td`): runs the launch gates without launching a VM, so it can be run **before an upgrade** to confirm a node will relaunch and re-attest rather than going offline. Exit codes: `0` ready, `1` blocked (QEMU wrong for OS, or topology uncharacterized — won't relaunch), `2` warning (gates pass but no registered measurement for this topology×QEMU — would 403 at attestation). `--target-os VERSION_ID` checks against the QEMU an OS upgrade would bring (skipping the live-QEMU hygiene gate, since the upgrade replaces it) so an OS upgrade can be pre-flighted. The QEMU-keyed `baselined_measurements` is what lets it distinguish "OS/QEMU is supported" from "we actually have a measurement for it" — the case where an H200 on 26.04/10.2.1 resolves and gates cleanly but has no registered 10.2.1 RTMR0. +- **`upgrade-host.yml` pre-flight gate**: runs `verify-host --target-os ` after computing the upgrade path and **before draining/shutting down the guest**; aborts the upgrade (unless `upgrade_preflight_override=true`) if the host wouldn't relaunch or attest at the target OS's QEMU — so an OS upgrade can't strand a node whose topology×QEMU has no registered measurement. +- **RTX Pro 6000 4-NUMA-node host support**: added the flat-fallback fingerprint `FlatTopology(gpu_count=8)` at QEMU `10.2.1` to `RTXPro6000Profile.baselined_measurements`. Hosts with more than 2 NUMA nodes fail `use_numa_topology`'s 2-node gate and launch on the flat path (single memory-backend, no PXB-PCIe grouping), which is a distinct guest topology → distinct RTMR0 from the 2-node NUMA hosts. The RTX entries are keyed under `10.2.1` (Ubuntu 26.04, confirmed by `discover-profile.sh` on `se-028` and `tlusa-9`), with the prior `10.1.0` numa entry retained for RTX hosts still on 25.10. **The matching RTMR0 for RTX flat @ 10.2.1 must be registered in chutes-ops `teeMeasurements` before this host can attest — the profile carries the fingerprint; the measurement follows.** +- `discover-profile.sh`: capture per-NVSwitch host NUMA node (`nvswitch.numa_nodes` in JSON, plus a report row) — the field that distinguishes otherwise-identical H200 chassis whose NVSwitches attach to a different NUMA node (e.g. Dell XE9680 node 1 vs KR6288 node 0), which changes RTMR0. +- `discover-profile.sh`: capture per-IB-PF host NUMA node for the passthrough candidates (`nic.passthrough_numa_nodes` in JSON, plus a report row) — retained as a diagnostic.

Without it, B200/B200_XEON6 fell back to the global 4-CPU reserve (188/284 vCPUs) instead of their 16-CPU reserve (176/272 vCPUs), producing a different `-smp` topology → a different RTMR0 than `main`'s baselined B200 measurements. Restored byte-identical to `main` so a later merge/rebase reconciles cleanly; B300 / H200 / RTX_PRO_6000 are unaffected (they use the default reserve). + +### Removed +- **InfiniBand passthrough for B200 / B200_XEON6** (`should_passthrough_infiniband` → `False`, matching H200/B300/RTX). It added no value — guest networking is virtio-net and NVLink fabric is host-side Fabric Manager (which works with IB off). Its only effect was to make RTMR0 vary by each host's IB NIC loadout (e.g. `am-b200-20` with 4 IB PFs vs `am-b200-57` with 20), forcing a separate measurement per loadout. With IB off, every B200 converges to one fingerprint `NumaTopology(gpu_nodes=(0,0,0,0,1,1,1,1))`.

Two checks: + - **QEMU host-readiness gate** (`verify_host_qemu_supported`, run before profile resolution): the host QEMU must be the build its OS release ships (`SUPPORTED_QEMU_BY_OS = {"25.10": "10.1.0", "26.04": "10.2.1"}`). QEMU generates the guest ACPI tables measured into RTMR0, so a different QEMU attests with an unbaselined RTMR0; tying it to the OS also enforces hosts run the release's security-patched build. Proactive operator check, not a security boundary — the real gate is the control-plane RTMR0 match. + - **Topology hard-match** in `detect_profile`: each `GpuProfile` declares `baselined_measurements`, a map of `QEMU version → set of host topology fingerprints` (`detection.host_topology_fingerprint`) with a registered RTMR0 measurement (RTMR0 = f(topology, QEMU), so a measurement is only valid for a specific topology×QEMU pair). `baselined_topologies` derives from it as the union across QEMU versions. Fingerprints are self-documenting value types in the new `chutes.guest.gpu.topology` module (see below): `NumaTopology(gpu_nodes, nvswitch_nodes, ib_nodes)` on the 2-node NUMA path (where each device→NUMA vector drives the guest PXB-PCIe grouping and thus RTMR0) or `FlatTopology(gpu_count, nvswitch_count, ib_count)` otherwise. The launch-time hard-match is deliberately QEMU-agnostic (uses the union): a host whose live topology isn't characterized at all is refused with "run discover-profile.sh and send the output." Populated for H200 / B200 / B200_XEON6 / RTX_PRO_6000 to mirror the authoritative chutes-ops `teeMeasurements` v1.3.1 (`values/chutes-api/values.yaml`). An empty map (e.g. B300, not yet characterized in sek8s) skips the launch check; verify-host will advise on such hosts since it can't confirm the measurement. +- **`chutes.guest.gpu.topology` module** — `NumaTopology` / `FlatTopology` frozen dataclasses that name every field of a topology fingerprint (per-device host-NUMA vectors vs device counts), replacing the previous opaque positional tuples (`("numa", …)` / `("flat", …)`). They are hashable value types, so they live in the `baselined_measurements` sets and support `fingerprint in baselined_topologies`; a `NumaTopology` never equals a `FlatTopology`, which is the guest-NUMA-path vs flat-fallback discriminator the string tag used to carry. Only *device* topology is captured — CPU/socket/RAM are pinned to profile constants and identical across a profile's hosts, so a host that differs only in NUMA-node count (the RTX 4-node case) or logical-CPU count is characterized by its topology, not named after the host. +- **`chutes.guest.verify` — standalone host-readiness check** (`verify-host` CLI, mirrors `run-td`): runs the launch gates without launching a VM, so it can be run **before an upgrade** to confirm a node will relaunch and re-attest rather than going offline. Exit codes: `0` ready, `1` blocked (QEMU wrong for OS, or topology uncharacterized — won't relaunch), `2` warning (gates pass but no registered measurement for this topology×QEMU — would 403 at attestation). `--target-os VERSION_ID` checks against the QEMU an OS upgrade would bring (skipping the live-QEMU hygiene gate, since the upgrade replaces it) so an OS upgrade can be pre-flighted. The QEMU-keyed `baselined_measurements` is what lets it distinguish "OS/QEMU is supported" from "we actually have a measurement for it" — the case where an H200 on 26.04/10.2.1 resolves and gates cleanly but has no registered 10.2.1 RTMR0. +- **`upgrade-host.yml` pre-flight gate**: runs `verify-host --target-os ` after computing the upgrade path and **before draining/shutting down the guest**; aborts the upgrade (unless `upgrade_preflight_override=true`) if the host wouldn't relaunch or attest at the target OS's QEMU — so an OS upgrade can't strand a node whose topology×QEMU has no registered measurement. +- **RTX Pro 6000 4-NUMA-node host support**: added the flat-fallback fingerprint `FlatTopology(gpu_count=8)` at QEMU `10.2.1` to `RTXPro6000Profile.baselined_measurements`. Hosts with more than 2 NUMA nodes fail `use_numa_topology`'s 2-node gate and launch on the flat path (single memory-backend, no PXB-PCIe grouping), which is a distinct guest topology → distinct RTMR0 from the 2-node NUMA hosts. The RTX entries are keyed under `10.2.1` (Ubuntu 26.04, confirmed by `discover-profile.sh` on `se-028` and `tlusa-9`), with the prior `10.1.0` numa entry retained for RTX hosts still on 25.10. **The matching RTMR0 for RTX flat @ 10.2.1 must be registered in chutes-ops `teeMeasurements` before this host can attest — the profile carries the fingerprint; the measurement follows.** +- `discover-profile.sh`: capture per-NVSwitch host NUMA node (`nvswitch.numa_nodes` in JSON, plus a report row) — the field that distinguishes otherwise-identical H200 chassis whose NVSwitches attach to a different NUMA node (e.g. Dell XE9680 node 1 vs KR6288 node 0), which changes RTMR0. +- `discover-profile.sh`: capture per-IB-PF host NUMA node for the passthrough candidates (`nic.passthrough_numa_nodes` in JSON, plus a report row) — retained as a diagnostic. The topology fingerprint keeps an IB axis (`ib_nodes` / `ib_count`) wired to `should_passthrough_infiniband`, so it is empty for every profile now that IB passthrough is removed (see Removed) but would automatically capture IB again if any profile re-enabled it. ### Changed - **Per-profile host CPU reserve.** `HOST_RESERVED_CPUS` is no longer a single @@ -30,6 +49,19 @@ Versioned with CalVer `YYYY.MM.PATCH` via `changelogs/ops/VERSION`.

Its only effect was to make RTMR0 vary by each host's IB NIC loadout (e.g. `am-b200-20` with 4 IB PFs vs `am-b200-57` with 20), forcing a separate measurement per loadout. With IB off, every B200 converges to one fingerprint `NumaTopology(gpu_nodes=(0,0,0,0,1,1,1,1))`.

The RTX entries are keyed under `10.2.1` (Ubuntu 26.04, confirmed by `discover-profile.sh` on `se-028` and `tlusa-9`), with the prior `10.1.0` numa entry retained for RTX hosts still on 25.10. **The matching RTMR0 for RTX flat @ 10.2.1 must be registered in chutes-ops `teeMeasurements` before this host can attest — the profile carries the fingerprint; the measurement follows.** -- `discover-profile.sh`: capture per-NVSwitch host NUMA node (`nvswitch.numa_nodes` in JSON, plus a report row) — the field that distinguishes otherwise-identical H200 chassis whose NVSwitches attach to a different NUMA node (e.g. Dell XE9680 node 1 vs KR6288 node 0), which changes RTMR0. -- `discover-profile.sh`: capture per-IB-PF host NUMA node for the passthrough candidates (`nic.passthrough_numa_nodes` in JSON, plus a report row) — retained as a diagnostic. The topology fingerprint keeps an IB axis (`ib_nodes` / `ib_count`) wired to `should_passthrough_infiniband`, so it is empty for every profile now that IB passthrough is removed (see Removed) but would automatically capture IB again if any profile re-enabled it. - -### Fixed -- **Re-incorporated per-profile `host_reserved_cpus` (#113)**, which landed on `main` after this branch forked from `07470ca`. Without it, B200/B200_XEON6 fell back to the global 4-CPU reserve (188/284 vCPUs) instead of their 16-CPU reserve (176/272 vCPUs), producing a different `-smp` topology → a different RTMR0 than `main`'s baselined B200 measurements. Restored byte-identical to `main` so a later merge/rebase reconciles cleanly; B300 / H200 / RTX_PRO_6000 are unaffected (they use the default reserve). - -### Removed -- **InfiniBand passthrough for B200 / B200_XEON6** (`should_passthrough_infiniband` → `False`, matching H200/B300/RTX). It added no value — guest networking is virtio-net and NVLink fabric is host-side Fabric Manager (which works with IB off). Its only effect was to make RTMR0 vary by each host's IB NIC loadout (e.g. `am-b200-20` with 4 IB PFs vs `am-b200-57` with 20), forcing a separate measurement per loadout. With IB off, every B200 converges to one fingerprint `NumaTopology(gpu_nodes=(0,0,0,0,1,1,1,1))`. The new no-IB RTMR0 is submitted to chutes-ops `teeMeasurements` after the fact (the profile carries the fingerprint; the measurement follows). diff --git a/changelogs/ops/unreleased/fix-host-tools.md b/changelogs/ops/unreleased/fix-host-tools.md deleted file mode 100644 index f6931e74..00000000 --- a/changelogs/ops/unreleased/fix-host-tools.md +++ /dev/null @@ -1,10 +0,0 @@ -### Fixed - -- `nvidia-gpu-tools` (and `chutes-reset-gpus`) now self-heal after a host OS - upgrade that changes the system Python (e.g. 25.10 → 26.04, Python 3.13 → - 3.14). `ensure_gpu_tools_available()` verifies the CLI actually runs instead - of trusting its presence on `PATH`, and rebuilds the bundled-wheel venv when - it was built for a different Python version.

Rather than mint and rotate a standalone credential, the service: + - **discovers pods + reads their labels/uid/phase** by shelling to the bundled + **`k3s crictl pods -o json`** through a restricted wrapper (the CRI sandbox metadata carries the + pod's k8s labels and UID — `k3s ctr` does **not** expose k8s pod labels). The agent consumes only + `chutes/config-id` (→ request path), `chutes/deployment-id` (→ shipped top-level, the one field + the validator cannot derive from `config_id`), and the pod UID (→ log path); the `chutes/chute-id` + label is present but unused, since the validator derives chute/miner/user identity server-side, and + - **reads log content** directly from `/var/log/pods/chutes__//*.log` (CRI + format, ` stdout F `; rotation is handled by kubelet). + + This removes the entire ServiceAccount / RBAC-manifest / projected-token surface the earlier draft + carried, and adds **no new Python dependency** (reuses the `run_command` shell pattern + + already-present `aiohttp`). The authorization ceiling becomes a **kernel-LSM (AppArmor)** boundary + over specific paths + the crictl socket, not an API-server RBAC ceiling. +- **Minimal request body — identity resolved server-side, not self-asserted.** The shipment body + carries the log lines plus `deployment_id` (`{"deployment_id": "…", "logs": [{ts, stream, log}]}`); + every **security-relevant** value the validator derives, because a value the guest could assert + about itself is strictly less trustworthy than one the infrastructure observes: + - `config_id` ← the request path. + - `deployment_id` ← the `chutes/deployment-id` pod label, shipped top-level. This is the **one + exception** to "derive server-side": it is non-security correlation metadata (used only for + Grafana filtering) that does **not** exist on the validator's `LaunchConfig` in the + pre-registration window, so the validator genuinely cannot derive it — the guest must supply it. + It is never used for auth, so self-asserting it carries no trust cost. + - `(miner_hotkey, vm_name)` — and therefore the server — ← the presented registry-tls leaf, + verified against the registered per-boot VM CA. `vm_name` is unique *per* `miner_hotkey`, and the + leaf binds to a specific server registered to a specific miner, so the cert is the durable + identity anchor. The guest sends **neither** `miner_hotkey` nor `vm_name`. + - `server_ip` is **not** sent: the CVM mTLS proxy (`cvm.chutes.ai` nginx) observes the source IP + and passes it to the API. It is also not a durable key — currently unique per server, but not + guaranteed to stay so — whereas the cert → `(miner, vm)` → server mapping is. +- **Push, with validator-controlled cutoff (simple).** The agent streams batches outbound and keys + off the response **status code** to decide whether to keep sending or stop: **`204 No Content` = + stop**, any other 2xx = keep sending, **`403`/`404` = terminal reject → stop and log the specific + reason** (`404` = unknown `config_id`; `403` = cert/ownership rejection — a cross-miner or + misconfigured shipment that will never succeed), and any *other* non-2xx or a connection error = + transient failure → retry with backoff (offset unchanged). All cutoff *logic* lives in the API + (default: stop at activation; per-chute override keeps it going). The agent holds **no** cutoff + policy of its own — it obeys the code. There is deliberately no local wall-clock backstop: a + never-activating, never-terminating pod is the validator's responsibility to cut off (it can + return `204` on its own timeout), and a deleted/reaped pod is stopped by the agent cancelling its + capture task (pod-gone). A guest-side timer would be an arbitrary cutoff policy that contradicts + "cutoff logic lives in the API," and risks truncating a legitimately slow warmup before the crash + we exist to capture. +- **Egress auth = mTLS, enforced.** Reuse the per-boot registry mTLS leaf (no new leaf, no + `setup_vm_tls` edit → no RTMR2 shift). The validator verifies the presented leaf against the + registered per-boot VM CA → `(miner_hotkey, vm_name)`, binding each shipment to the attested boot. + There is no non-mTLS path. +- **Streaming with a bounded window + offset checkpoint (deterministic memory).** The target is + **all** chute pods (until the validator cuts each off), so the read path must not re-read whole + files. The **log file on disk is the durable buffer**; the agent tails only a bounded window + (`buffer_bytes`) into RAM per pod, so total memory is deterministic — `buffer_bytes × pods`, and + there is at most one chute pod per GPU. A single streaming coroutine reads the next window only + after shipping the current one, so a slow validator naturally **pauses reading** (backpressure); + the unread bytes stay on disk. Read position is a **byte offset per file, keyed by inode** (so it + follows kubelet rotation — a rename keeps the inode — and resets on truncation / a new inode). The + **committed offset advances only on a successful ship**, and is persisted to a checkpoint + `{config_id → {inode → offset}}`, so on any restart the stream resumes from the last durably-shipped + position. Per-line CRI `ts` is still sent; the validator dedupes on `(config_id, ts)` (nanosecond + ts is effectively unique per line), which backstops the rotation/restart edges where an offset is + re-read. **No `seq`/gap marker is sent** — retry-until-shipped + commit-on-success already prevent + gaps. **Only complete logical lines are shipped:** a window boundary that cuts a physical line, and + a CRI `P`-run whose `F` has not arrived, are both held back (the offset is not advanced past them), + so the validator never receives a partial line and needs no partial-handling. The checkpoint is + reconciled to the live pod set on every poll (dropping keys for pods no longer present to prevent + unbounded growth) and evicted on pod-delete. + +--- + +## API Changes + +The guest agent is a **client**; it calls the validator. No inbound API is added on the guest. +- **Calls out**: the log-ship endpoint (validator) presenting the mTLS leaf. **Must target the + dedicated CVM mTLS host — `cvm.chutes.ai`**, a **separate proxy** that fronts *all* CVM mTLS + endpoints (a vendor-neutral consolidation of what `tdx-attestation.chutes.ai` used to serve + piecemeal), **not** plain `api.chutes.ai`, which does not verify client certs.

Two follow-ups: + - **Multi-container:** the guest ships **only the `chute` container** so the stream is monotonic in + `ts` (required by the single high-watermark). Capturing more than one container per pod would + need a per-line **container id** stored server-side (Loki label) so reads can select a container. + - **`413` / body size:** confirm `cvm.chutes.ai`'s nginx `client_max_body_size` is comfortably above + the guest's max body; the guest now splits on `413` regardless, but a generous limit avoids the + extra round-trips. +- **Validator-side deltas (all now implemented in `chutes-api` main; kept for reference):** + 1. Route the ingest endpoint (`/instances/launch_config/{config_id}/logs`, §1) through the new + **dedicated `cvm.chutes.ai` CVM mTLS proxy** and gate it on that proxy's injected secret header + (the API-side enforcement described in §API Changes). No change to the guest, which just presents + the mTLS leaf. + 2. Dedupe on **`(config_id, ts)`** (nanosecond) so agent restarts and kubelet log rotation stay + idempotent. No `seq` is sent — reliable delivery (retry + commit-offset-on-success) makes it + redundant. + 3. Resolve identity server-side: `config_id` from the path, `(miner_hotkey, vm_name)` + server from + the verified mTLS leaf, `chute_id`/`miner_hotkey`/`user_id` from `LaunchConfig`→`Chute`, source + IP from the proxy. The guest self-asserts none of these; the request body is + `{"deployment_id": "", "logs": [{ts, stream, log}]}` — `deployment_id` (from the pod label) + is the only field shipped because the validator cannot derive it from `config_id`. + 4. Return **`204 No Content`** to signal cutoff (any other 2xx keeps capture going); return + **`404`** for an unknown `config_id` and **`403`** for a cert/ownership rejection — the guest + treats both as terminal (stops + logs), so these must be reserved for genuinely unrecoverable + shipments, not transient errors. + 5. **Own the never-activating cutoff.** The guest has no wall-clock backstop (removed by design), + so a pod that never activates and never terminates will keep shipping until the validator + returns `204`. The API must cut these off on its own timeout (e.g. `204` once a launch config is + `failed_at` + grace, or after a max capture window) rather than relying on the guest to stop. +- **Phase 2 (separate change):** repoint the readiness/liveness probe off `:8001/_alive` → 8000 + **first** (`chutes-miner api/k8s/operator.py:_get_probe_port`), migrate `log_prober` and the + `stream_logs`/`encrypted_logs` paths onto the agent/central store, extend the agent to ship + running logs (default-off), then retire the 8001 server + NodePort and the `encrypted_logs` ECIES + path. The job-output upload of `/tmp/_chute.log*` (`chutes/chute/job.py:236`) depends on the tee'd + file, not the 8001 server, so it is unaffected. +- **Backward compat:** Phase 1 leaves the 8001 server and existing log proxies fully in place; the + agent is purely additive. diff --git a/src/sek8s/pyproject.toml b/src/sek8s/pyproject.toml index 7fd32d11..68fd0349 100644 --- a/src/sek8s/pyproject.toml +++ b/src/sek8s/pyproject.toml @@ -34,6 +34,7 @@ sek8s-common = {path = "../sek8s-common", develop = true} admission-controller = 'sek8s.services.admission_controller:run' attestation-service = 'sek8s.services.attestation:run' system-manager = 'sek8s.services.manager:run' +chute-log-shipper = 'sek8s.services.log_shipper:run' [build-system] requires = ["poetry-core"] diff --git a/src/sek8s/sek8s/log_shipper/__init__.py b/src/sek8s/sek8s/log_shipper/__init__.py new file mode 100644 index 00000000..df52ca05 --- /dev/null +++ b/src/sek8s/sek8s/log_shipper/__init__.py @@ -0,0 +1,5 @@ +"""Chute log shipper: standalone VM agent that discovers chute pods via CRI, +reads their logs off disk, and streams them to the validator over mTLS. + +See docs/specs/chute-log-shipper.md for the design. +""" diff --git a/src/sek8s/sek8s/log_shipper/agent.py b/src/sek8s/sek8s/log_shipper/agent.py new file mode 100644 index 00000000..6ea2b7d2 --- /dev/null +++ b/src/sek8s/sek8s/log_shipper/agent.py @@ -0,0 +1,152 @@ +"""Orchestrator: poll CRI for chute pods, run one capture task per pod, and +reconcile the offset checkpoints to the live pod set. + +The agent is fail-closed: a crictl error or a dead validator endpoint never +crashes the loop — it logs, backs off, and retries on the next poll. +""" + +from __future__ import annotations + +import asyncio +import ssl +from typing import Dict, List, Optional, Set, cast + +import aiohttp +from loguru import logger + +from .checkpoint import CheckpointStore +from .config import LogShipperConfig +from .crictl import CrictlError, list_chute_pods +from .models import ChutePod +from .shipper import PodLogShipper + + +def build_ssl_context(config: LogShipperConfig) -> ssl.SSLContext: + """TLS context presenting the registry mTLS leaf as the client identity. + + Server verification stays on (default CA bundle) — the CVM proxy presents a + publicly-trusted cert. + """ + context = ssl.create_default_context() + context.load_cert_chain( + certfile=str(config.mtls_cert_path), keyfile=str(config.mtls_key_path) + ) + return context + + +class LogShipperAgent: + """Discovers chute pods and manages their per-pod capture tasks.""" + + def __init__(self, config: LogShipperConfig): + self._config = config + self._checkpoints = CheckpointStore(config.checkpoint_path) + # config_id -> running capture task + self._tasks: Dict[str, asyncio.Task] = {} + # config_id -> pod being captured (for logging) + self._pods: Dict[str, ChutePod] = {} + # config_ids whose capture finished (stop/backstop) — not re-spawned while live + self._done: Set[str] = set() + self._session: Optional[aiohttp.ClientSession] = None # set in run() + + async def run(self) -> None: + await self._checkpoints.load() + context = build_ssl_context(self._config) + connector = aiohttp.TCPConnector(ssl=context) + async with aiohttp.ClientSession(connector=connector) as session: + self._session = session + try: + while True: + await self._poll_once() + await asyncio.sleep(self._config.poll_interval_seconds) + finally: + await self._shutdown() + + async def _poll_once(self) -> None: + try: + pods = await list_chute_pods(self._config) + except CrictlError as exc: + logger.warning("Pod discovery failed (will retry): {}", exc) + return + + live_ids = {pod.config_id for pod in pods} + self._reap_finished() + await self._drop_gone(live_ids) + self._spawn_new(pods, live_ids) + await self._checkpoints.reconcile(live_ids) + + def _reap_finished(self) -> None: + """Move completed tasks out of the active set.""" + for config_id, task in list(self._tasks.items()): + if not task.done(): + continue + self._tasks.pop(config_id, None) + self._pods.pop(config_id, None) + if task.cancelled(): + continue + exc = task.exception() + if exc is not None: + logger.error( + "Capture task for config_id={} errored: {}", config_id, exc + ) + self._done.add(config_id) + + async def _drop_gone(self, live_ids: Set[str]) -> None: + """Cancel captures and forget state for pods that have disappeared.""" + tracked = set(self._tasks) | self._done + for config_id in tracked - live_ids: + task = self._tasks.pop(config_id, None) + if task is not None and not task.done(): + task.cancel() + self._pods.pop(config_id, None) + self._done.discard(config_id) + await self._checkpoints.evict(config_id) + + def _spawn_new(self, pods: List[ChutePod], live_ids: Set[str]) -> None: + """Start capture tasks for newly-seen pods, respecting the concurrency cap.""" + candidates = [ + pod + for pod in pods + if pod.config_id not in self._tasks and pod.config_id not in self._done + ] + available = self._config.max_concurrent_pods - len(self._tasks) + if available <= 0: + if candidates: + logger.warning( + "At capture capacity ({} pods);

It added no value — guest networking is virtio-net and NVLink fabric is host-side Fabric Manager (which works with IB off). Its only effect was to make RTMR0 vary by each host's IB NIC loadout (e.g. `am-b200-20` with 4 IB PFs vs `am-b200-57` with 20), forcing a separate measurement per loadout. With IB off, every B200 converges to one fingerprint `NumaTopology(gpu_nodes=(0,0,0,0,1,1,1,1))`.

This is what the miner-VM build runs; there is no separate pre-LUKS RTMR3 + step. + - **`generate --register rtmr0`** — just the version-level MRTD + per-topology RTMR0 via the + tdx-measure fork (offline, any x86-64 Linux — no TDX/GPU) as a JSON block; `--profile` does one, + empty does all. A standalone partial (a full `generate` computes RTMR0 inline). + - **`generate --register rtmr3`** — just the version-level RTMR3 (SHA-384 chain over the image's + `/etc/tdx-measure.conf` files), mounting the root read-only. `LUKS_PASSPHRASE` unlocks an + encrypted root; always recomputes **fresh** (the real value, no cached/reused fallback). Used by + the partner GPU-VM build (`tee-gpu-vm.yml`), which has no aggregation. +- **`src/chutes-cvm/install.sh` — the single source of truth for install** (replaces + `host-tools/scripts/provision/setup-chutes-cvm.sh`). One script owns both fetch and install, and + picks its mode: run from a checkout (ansible / build / dev) → editable install from that checkout + (a `git pull` updates the code, no reinstall); `curl -sSL …/src/chutes-cvm/install.sh | bash` → + sparse shallow-fetch (`host-tools/` + `firmware/` + `src/chutes-cvm/`) into a **temporary** dir, + non-editable install (CLI + bundled nvidia-gpu-tools into a persistent venv, firmware copied next + to it), then delete the temp checkout. The sparse path-list and the install steps live here + exactly once; the `host_tools` ansible role and the guest build both invoke it. A standalone + install is fully launch-capable — no manual `git clone`, no lingering source, no PyPI, no R2. + `chutes-cvm setup-host` no longer installs/verifies the CLI or gpu-tools (install.sh installs + them; the launch path verifies gpu-tools where it matters); its `--install-tools-only` flag and + the `install_dependencies` step are removed. +- **`make bundle-gpu-tools`** — discoverable maintainer target that rebuilds the vendored + nvidia-gpu-tools wheel into the package (recipe at `src/chutes-cvm/tools/gpu-tools/`). +- **`chutes-cvm image-set` / `chutes-cvm config` / `chutes-cvm vfio-wedged`** — the + image-set manifest tool, the config renderer, and the PCI-passthrough-wedged check are + now first-class subcommands, so every caller routes through the one console script. +- **`chutes-cvm launch`** — end-to-end VM launch orchestrator (verify host → volumes → network → + boot) from `config.yaml`. This is the one command a miner uses to bring a VM up. It calls the + low-level QEMU primitive, now the hidden `chutes-cvm launch-vm`. +- **`chutes-cvm download` / `init` / `stop` / `down`** — the quick-launch modes that used to be + flags are now first-class commands: `download [--debug]` fetches + verifies a base image set, + `init` scaffolds a `config.yaml`, `stop` stops only the VM (leaving the bridge up), and `down` + tears the whole environment down (VM + bridge + benchmark-netlog). +- **`chutes-cvm preflight`** — asks the control plane whether this host class can launch. Captures + the host's platform metadata (discover-profile), signs it with the miner hotkey (sr25519), and + POSTs it to the API, which owns the fingerprint and returns accepted / pending / unknown. Submits + the profile when unknown (unless `--dry-run`). Exit 0 accepted / 1 error (fail-closed) / 2 not-yet. + Adds `substrate-interface` to the chutes-cvm package for the signature. + +### Changed +- **Consolidated the host entrypoint scripts into the `chutes-cvm` CLI.** The thin wrapper + scripts `run-td`, `verify-host`, `setup-tdx-host`, `tune-host.sh`, `restore-host.sh` and the + `host-tools/bin/chutes-*` PATH delegators are removed; their operations are now `chutes-cvm` + subcommands: `launch`, `verify-host`, `setup-host`, `tune-host`, `restore-host`, `reset-gpus` + (plus `discover-profile`). Logic still lives in the `chutes_cvm.guest` / `chutes_cvm.host` + modules; the CLI is a thin front door. `discover-profile.sh` is deliberately kept as a + standalone script (bundled with the package). Callers invoke the `chutes-cvm` console script + installed by the package's `install.sh`, rather than the removed `host-tools/bin/` symlinks. +- **The guest build's measurement phase is entirely CLI-owned — no measurement roles.** The + `compute-rtmr0` / `compute-rtmr1-2` / `compute-rtmr3` / `aggregate-measurements` roles and their + shell scripts are removed; the miner-VM build calls `chutes-cvm measurements generate` once, + POST-luks, for every register. The CLI unlocks the encrypted root with `LUKS_PASSPHRASE` to read + RTMR3's userspace files (always fresh — no cached-value reuse), so there is no longer a separate + pre-LUKS RTMR3 stage. `libguestfs-tools` (guestmount) is now a build-host prereq + (`build-setup.yml`); `tee-gpu-vm.yml` calls `measurements generate --register rtmr3` inline. The + generator's firmware / selftest-fixture paths resolve via `chutes_cvm.paths`. +- **The package-level CLI dispatcher moved to the package root** — `chutes_cvm/guest/cli.py` → + `chutes_cvm/cli.py` (console script `chutes-cvm` → `chutes_cvm.cli:main`), since it routes to the + host, guest, and measurement subpackages rather than belonging to `guest/`. +- **`chutes-cvm` is now a real Python package under `src/chutes-cvm/`** (import + `chutes_cvm`, published to PyPI), instead of a loose module tree on `PYTHONPATH` at + `host-tools/scripts/chutes/`. The rename from `chutes` to `chutes_cvm` avoids colliding + with the Chutes platform SDK once installed. The offline measurement engine + (`guest-tools/measurement/*.py`) moved into `chutes_cvm.measurement`, dropping its + `sys.path` shims. +- **Host provisioning installs the package** — `host_tools` stages and runs the package's + `install.sh`, which fetches + `pip install -e`'s the package into a venv and puts the + `chutes-cvm` console script on PATH (with its deps: pyyaml/jsonschema/substrate-interface). Host + ansible + `quick-launch.sh` + call `chutes-cvm ` instead of `python3 -m chutes.guest.*`, so dependency-bearing + commands (`config`, and the upcoming `preflight`) run with their deps available. The sparse + checkout now includes `src/chutes-cvm/`. Guest image build keeps `PYTHONPATH` (stdlib commands + only). Set `CHUTES_CVM_PYPI=1` to install from PyPI instead of the checkout. +- **The package is self-contained — no repo-layout assumptions.** The built nvidia-gpu-tools + wheel moved into the package (`chutes_cvm/scripts/gpu-tools/`, bundled in the wheel; its + maintainer build recipe lives at `src/chutes-cvm/tools/gpu-tools/`, run via `make + bundle-gpu-tools`, and builds the wheel into the package), and the default launch-config lookup + is now `./config.yaml` (where + `chutes-cvm init` writes it) / `$CHUTES_CVM_CONFIG` rather than a checkout path.

(The admission path happens to +use stdlib ``logging``, which never renders locals; the guest mixes both libraries, +so the guarantee is set here rather than per call site.) + +So every service entrypoint installs its own sink with ``diagnose=False``. That is +the *only* setting this module changes from loguru's defaults; everything else is +left alone deliberately, and two of those defaults are worth knowing: + +- ``backtrace`` stays on (default ``True``). Only values are suppressed — the + traceback is untouched, so an exception still logs every frame from the catch + point down to the raise with file, line, and source line, plus the call chain + above the catching point. It renders frames, never values, and that stack is + the whole diagnostic story when ``journalctl`` through the status API is the + only view of a prod guest. +- ``enqueue`` stays off (default ``False``). Enqueueing would move the sink write + off the event loop, but queued records are lost if the process dies before the + worker thread drains them — and this guest is built to die abruptly + (``OnFailure=poweroff.target``, ``FailureAction=poweroff-force``) with the + journal as its only forensic surface, so the last line before a shutdown is + exactly the one worth keeping. Its multiprocess-safety benefit does not apply + either: every service is a single uvicorn process (no ``workers``) or a single + asyncio daemon.
