Host-side KMS is reachable over TLS. +2. Host-side Gateway Admin API accepts configuration. +3. Gateway obtains a wildcard certificate for `*.DSTACK_E2E_BASE_DOMAIN` from + Pebble using the mock Cloudflare DNS API. +4. VMM API becomes reachable. +5. A real nginx app CVM boots with `kms_enabled=true` and `gateway_enabled=true`. +6. `curl -k` through the Gateway SNI route returns the nginx welcome page. + +Artifacts are written under `state/work/`. + +## Notes / flexibility gaps + +- This is a dev compose KMS/Gateway setup. KMS and Gateway key material is + generated under `state/`; the allowlist returns `gatewayAppId = "any"`, which + matches the host-side tdxlab-style deployment and avoids requiring Gateway to + be a CVM. +- `dstackup install` is systemd-oriented; this suite renders `vmm.toml`, + `kms.toml`, `gateway.toml`, and `auth-allowlist.json` itself. +- Running VMM in a container depends on the container image having a QEMU build + that supports the target TEE platform. The runtime Dockerfile uses Intel's + kobuk-team TDX PPA for QEMU, matching the dstack-k8s compose deployment. +- Host API is vsock-only by design. The suite therefore uses privileged host + networking and a separate `DSTACK_E2E_HOST_API_PORT` to avoid conflicts with + other VMM instances. diff --git a/test-suites/full-stack-compose/compose.yml b/test-suites/full-stack-compose/compose.yml new file mode 100644 index 000000000..e12e74446 --- /dev/null +++ b/test-suites/full-stack-compose/compose.yml @@ -0,0 +1,266 @@ +# SPDX-FileCopyrightText: © 2026 Phala Network +# +# SPDX-License-Identifier: Apache-2.0 + +name: dstack-full-e2e + +x-suite-env: &suite-env + DSTACK_E2E_STATE_DIR: /suite-state + DSTACK_E2E_CONFIG_DIR: /suite-state/config + DSTACK_E2E_RUN_DIR: /suite-state/run + DSTACK_E2E_VM_DIR: /suite-state/vm + DSTACK_E2E_VOLUMES_DIR: /suite-state/volumes + DSTACK_E2E_IMAGE_ROOT: /images + DSTACK_E2E_IMAGE_NAME: ${DSTACK_E2E_IMAGE_NAME:-dstack-0.6.0} + DSTACK_E2E_PLATFORM: ${DSTACK_E2E_PLATFORM:-tdx} + DSTACK_E2E_VMM_PORT: ${DSTACK_E2E_VMM_PORT:-29080} + DSTACK_E2E_AUTH_PORT: ${DSTACK_E2E_AUTH_PORT:-28011} + DSTACK_E2E_KMS_HOST_PORT: ${DSTACK_E2E_KMS_HOST_PORT:-28082} + DSTACK_E2E_GATEWAY_RPC_HOST_PORT: ${DSTACK_E2E_GATEWAY_RPC_HOST_PORT:-28000} + DSTACK_E2E_GATEWAY_ADMIN_HOST_PORT: ${DSTACK_E2E_GATEWAY_ADMIN_HOST_PORT:-28001} + DSTACK_E2E_GATEWAY_PROXY_HOST_PORT: ${DSTACK_E2E_GATEWAY_PROXY_HOST_PORT:-28443} + DSTACK_E2E_GATEWAY_WG_HOST_PORT: ${DSTACK_E2E_GATEWAY_WG_HOST_PORT:-28120} + DSTACK_E2E_GATEWAY_WG_INTERFACE: ${DSTACK_E2E_GATEWAY_WG_INTERFACE:-wg-ds-e2e} + DSTACK_E2E_GATEWAY_WG_IP: ${DSTACK_E2E_GATEWAY_WG_IP:-10.8.0.1/16} + DSTACK_E2E_GATEWAY_WG_RESERVED_NET: ${DSTACK_E2E_GATEWAY_WG_RESERVED_NET:-10.8.0.1/32} + DSTACK_E2E_GATEWAY_WG_CLIENT_RANGE: ${DSTACK_E2E_GATEWAY_WG_CLIENT_RANGE:-10.8.0.0/18} + DSTACK_E2E_GATEWAY_APP_ID: ${DSTACK_E2E_GATEWAY_APP_ID:-any} + DSTACK_E2E_KEY_PROVIDER_PORT: ${DSTACK_E2E_KEY_PROVIDER_PORT:-13443} + DSTACK_E2E_HOST_API_PORT: ${DSTACK_E2E_HOST_API_PORT:-20011} + DSTACK_E2E_CID_START: ${DSTACK_E2E_CID_START:-15000} + DSTACK_E2E_QGS_PORT: ${DSTACK_E2E_QGS_PORT:-4050} + DSTACK_E2E_QEMU_PATH: ${DSTACK_E2E_QEMU_PATH:-/usr/bin/qemu-system-x86_64} + DSTACK_E2E_BASE_DOMAIN: ${DSTACK_E2E_BASE_DOMAIN:-e2e.test} + DSTACK_E2E_MOCK_CF_HTTP_PORT: ${DSTACK_E2E_MOCK_CF_HTTP_PORT:-38080} + DSTACK_E2E_PEBBLE_HTTP_PORT: ${DSTACK_E2E_PEBBLE_HTTP_PORT:-34000} + DSTACK_E2E_APP_IMAGE: ${DSTACK_E2E_APP_IMAGE:-nginx:alpine} + DSTACK_E2E_APP_NAME: ${DSTACK_E2E_APP_NAME:-dstack-e2e-nginx} + DSTACK_E2E_NAME_PREFIX: ${DSTACK_E2E_NAME_PREFIX:-dstack-e2e} + DSTACK_E2E_ALLOW_UNPINNED_IMAGE: ${DSTACK_E2E_ALLOW_UNPINNED_IMAGE:-false} + +services: + init-config: + build: + context: ./runtime + image: dstack-e2e-runtime:local + network_mode: host + volumes: + - ./state:/suite-state + - ./scripts:/suite/scripts:ro + - ${DSTACK_E2E_IMAGE_STORE:-../../../build/images}:/images:ro + environment: + <<: *suite-env + command: ["/suite/scripts/render-config.sh"] + + mock-cf-dns-api: + build: + context: ./mock-cf-dns + image: dstack-e2e-mock-cf-dns:local + networks: + e2e-net: + ipv4_address: 172.31.0.10 + ports: + - "127.0.0.1:${DSTACK_E2E_MOCK_CF_HTTP_PORT:-38080}:8080" + environment: + PORT: 8080 + DEBUG: ${DSTACK_E2E_MOCK_DEBUG:-false} + MOCK_CF_ZONES: ${DSTACK_E2E_BASE_DOMAIN:-e2e.test},test,local + healthcheck: + test: ["CMD", "python", "-c", "import urllib.request; urllib.request.urlopen('http://127.0.0.1:8080/health')"] + interval: 5s + timeout: 3s + retries: 10 + + pebble: + # Custom Pebble build used by the existing gateway E2E suite.

Real nginx app CVMs boot with `kms_enabled=true` and - `gateway_enabled=true`. -6. On TDX, v3 requirements resolve one CVM to legacy attestation and one to - lite; both complete boot-time KMS key provisioning. -7. `curl -k` through each Gateway SNI route returns the nginx welcome page. -8. KMS and Gateway state can be captured in canonical, diffable artifacts. - -`run-upgrade-e2e.sh` additionally checks KMS key continuity, Gateway persistence, -old-to-new config/storage compatibility, and zero-failure CVM WireGuard traffic -during the Gateway replacement. - -Artifacts are written under `state/work/`. - -## Notes / flexibility gaps - -- This is a dev compose KMS/Gateway setup. KMS and Gateway key material is - generated under `state/`; the allowlist returns `gatewayAppId = "any"`, which - matches the host-side tdxlab-style deployment and avoids requiring Gateway to - be a CVM. -- `dstackup install` is systemd-oriented; this suite renders `vmm.toml`, - `kms.toml`, `gateway.toml`, and `auth-allowlist.json` itself. -- Running VMM in a container depends on the container image having a QEMU build - that supports the target TEE platform.

The bootstrap response must contain non-empty attestation. +3. Boot the forced-legacy app through KMS 0.5.8 and record the KMS CA SPKI, + root k256 public key, and the app's derived environment-encryption public + key. (The expected onboarding path reissues the self-signed CA certificate, + so its DER bytes/expiry are not a stable identity; its private key/SPKI is.) +4. Deploy current KMS in a new Local-Key-Provider TDX CVM, authorize its exact + measurement, and call `Onboard.Onboard` against KMS 0.5.8. This exercises the + production RA-TLS root-key replication path; it is not a directory copy. +5. Require all recorded identities/derived keys to be byte-for-byte equal, + stop KMS 0.5.8, and force the legacy app to boot against only current KMS. +6. Boot a fresh forced-lite app against current KMS. Both modes must reach + `boot_progress=done`, which occurs after boot-time `GetAppKey` succeeds. + +The artifact server journal must contain two successful GETs for the exact +measured OS archive (one from each fresh KMS data disk). VM logs are also +rejected if they say image verification or self-authorization is disabled. + +### Gateway 0.5.8 to current + +1. Deploy two Gateway 0.5.8 TDX CVMs under one pinned Gateway app ID. Both get + app keys and RA-TLS certificates from KMS; their environment is encrypted by + VMM/KMS. +2. Form a WaveKV cluster, configure Pebble/Cloudflare mock DNS once, and require + the second node to receive the configuration and wildcard certificate. +3. Verify the legacy and lite app SNI routes through **both** Gateway nodes. +4. Snapshot each node's UUID, CVM registrations/IPs, certbot configuration, DNS + credential metadata, ZT domains, and wildcard-certificate fingerprint. +5. Run a rapid HA probe that alternates the preferred physical Gateway for + every legacy/lite request and falls back to the other node in the same cycle. +6. Stop, update the measured app compose, and restart node 1 on current KMS; + require it to carry both apps and retain all durable state. Repeat for node 2. +7. Require zero failed HA cycles and unchanged durable state/certificates. +8. Force certificate issuance through each upgraded node against a mock DNS API + that rejects anything except the original bearer token.

The GPU operates in confidential compute mode, encrypting data during computation. Both the CPU TEE and NVIDIA GPU provide hardware isolation together. If either component fails verification, the security model breaks. +GPUs are passed through via VFIO to the TEE-protected CVM. Before key provisioning, `dstack-util setup` inventories every VGA/3D-controller PCI function, compares that count with `vm_config.num_gpus`, and runs NVIDIA's local `nvattest` verifier over every NVIDIA-driver-visible GPU with a fresh nonce. A mandatory relying-party policy requires secure boot and disabled debug status. Separate fail-closed `nvidia-smi` queries require the current CC feature to be ON and DevTools mode to be OFF. Only then does dstack set the GPU ready state. ### Dual Attestation -GPU workloads require verification of both hardware components. The CPU TEE provides the quote that verifies CPU and memory isolation. NVIDIA's Remote Attestation Service (NRAS) independently verifies the GPU is genuine and running in confidential mode. Both attestations must pass for complete verification. +GPU workloads require verification of both hardware components. The CPU TEE quote verifies the CVM and its measured guest code. NVIDIA-signed evidence, checked against NVIDIA RIMs and certificate status by `nvattest`, verifies the GPU appraisal. After the ready-state operation succeeds, dstack emits a `gpu-attestation` launch event before `system-ready`. Its versioned payload records the number of appraised devices, policy version, asserted CC/DevTools state, and SHA-256 of the complete nvattest JSON output (claims and detached EAT). On TDX this event is append-only in RTMR3; it is never derived from application-controlled `report_data`. + +A verifier must replay the measured event log, require exactly one pre-`system-ready` `gpu-attestation` event when GPU protection is required, require `devices == vm_config.num_gpus > 0`, and accept the named policy version. The raw file under `/run/nvidia-gpu-attestation/attestation.out` is not trusted by itself; if it is supplied for inspection, its digest must match the event. + +### GPU Threat Model and Lifetime + +The GPU gate assumes a malicious host/VMM and untrusted host-provided PCI topology, while trusting the CPU TEE, the measured dstack guest/kernel, NVIDIA hardware/firmware roots, and the cryptography used by both attestation chains. Availability is out of scope. + +The event makes the following **boot-time** statement: immediately before key provisioning, all attached VGA/3D PCI functions were NVIDIA devices, their count matched the quote-bound VM configuration, nvattest returned one fresh production-policy claim for each device, CC was ON, DevTools was OFF, and setting the GPU ready state succeeded. This closes these cases: + +- A GPU-less launch cannot be presented as a GPU-verified launch: it has `num_gpus == 0` and no `gpu-attestation` event. +- A mixed launch cannot attest only its TEE-capable subset. Non-NVIDIA display GPUs are rejected, and the sysfs, `vm_config`, and nvattest claim counts must all agree. A non-CC NVIDIA GPU either prevents evidence collection/appraisal or causes that count/policy check to fail. +- Copying another CVM's result into a file or `report_data` does not work. Only measured pre-application code can place the event before `system-ready`, and event-log replay binds it to the quoted RTMR/PCR value. + +This is **not a lifetime or physical co-location guarantee**. After `system-ready`, an application with sufficient guest privileges can unload the NVIDIA driver, and a malicious host may attempt PCI hot-remove/replacement or proxy GPU traffic. The boot event remains a true historical statement but does not prove that the same device is still attached. dstack also cannot rule out a live relay/cuckoo attack to a genuine remote GPU: current Hopper/Blackwell deployments do not provide a CPU-TEE-verifiable TEE-I/O/TDISP device binding. Applications that mutate the driver or PCI topology are outside this guarantee; higher-assurance deployments must prevent that behavior and re-attest before using a newly initialized GPU. + +AMD SEV-SNP has no runtime measurement register in the current dstack stack. The local boot gate can still fail closed, but a `gpu-attestation` event carried beside an SNP report is not remotely bound to that report and must not be accepted as dual-attestation evidence. SNP needs a measured vTPM/PCR channel before it can provide the same remote binding. ### AI Workload Protection @@ -156,6 +172,12 @@ Use this checklist to verify a workload running in a dstack CVM. - [ ] Config commitment matches the expected app/config target (on AWS: PCR14 replay; PCR8 is an optional shortcut — see the [AWS verifier runbook](../aws-ec2-production-verifier-runbook.md)) - [ ] reportData contains your challenge (replay protection) +**GPU verification (when required):** +- [ ] `vm_config.num_gpus` is greater than zero and matches the expected deployment +- [ ] Exactly one `gpu-attestation` event appears before `system-ready` +- [ ] The event device count matches `vm_config.num_gpus`, and its policy/CC/DevTools fields match the production policy +- [ ] The platform binds the event log to a quoted RTMR/PCR (do not accept it from current SEV-SNP evidence) + **Key management verification:** - [ ] key-provider matches expected KMS identity - [ ] KMS attestation is valid diff --git a/dstack/dstack-util/src/system_setup.rs b/dstack/dstack-util/src/system_setup.rs index 73823d254..be6652fd5 100644 --- a/dstack/dstack-util/src/system_setup.rs +++ b/dstack/dstack-util/src/system_setup.rs @@ -1080,28 +1080,90 @@ mod gpu { const NVATTEST: &str = "/usr/bin/nvattest"; const NVIDIA_SMI: &str = "/usr/bin/nvidia-smi"; + const NVIDIA_POLICY: &str = "/usr/share/nvattest/dstack-gpu-attestation.rego"; const ATTESTATION_OUTPUT: &str = "/run/nvidia-gpu-attestation/attestation.out"; const ATTESTATION_TIMEOUT: Duration = Duration::from_secs(300); const NVIDIA_SMI_TIMEOUT: Duration = Duration::from_secs(60); + const EVENT_VERSION: u32 = 1; + const POLICY_VERSION: &str = "nvidia-cc-production-v1"; - /// True if a passed-through NVIDIA GPU is present, detected via sysfs PCI - /// (vendor 0x10de, class VGA 0x0300xx or 3D controller 0x0302xx) so it - /// works even before the nvidia driver is loaded.

Non-NVIDIA display GPUs are rejected, and the sysfs, `vm_config`, and nvattest claim counts must all agree. A non-CC NVIDIA GPU either prevents evidence collection/appraisal or causes that count/policy check to fail. +- A mixed launch cannot attest only its TEE-capable subset. Non-NVIDIA display GPUs are rejected, and the sysfs, `vm_config`, and nvattest claim counts must all agree. A non-CC NVIDIA GPU either prevents evidence collection/appraisal or causes the default appraisal, application policy, or CC-state check to fail. - Copying another CVM's result into a file or `report_data` does not work. Only measured pre-application code can place the event before `system-ready`, and event-log replay binds it to the quoted RTMR/PCR value. This is **not a lifetime or physical co-location guarantee**. After `system-ready`, an application with sufficient guest privileges can unload the NVIDIA driver, and a malicious host may attempt PCI hot-remove/replacement or proxy GPU traffic. The boot event remains a true historical statement but does not prove that the same device is still attached. dstack also cannot rule out a live relay/cuckoo attack to a genuine remote GPU: current Hopper/Blackwell deployments do not provide a CPU-TEE-verifiable TEE-I/O/TDISP device binding. Applications that mutate the driver or PCI topology are outside this guarantee; higher-assurance deployments must prevent that behavior and re-attest before using a newly initialized GPU. @@ -174,8

It must define the boolean entrypoint `data.policy.nv_match` in `package policy`. - `allow_devtools` (boolean, default `false`): permit NVIDIA DevTools mode. Production applications should leave this disabled because DevTools removes the expected GPU memory-confidentiality guarantee. +- `allow_debug` (boolean, default `false`): permit an attestation claim whose `dbgstat` is `enabled`. +- `allow_insecure_boot` (boolean, default `false`): permit an attestation claim whose GPU `secboot` value is false. After measuring `compose-hash`, dstack enters the GPU setup gate. If GPUs are configured, it attests them, applies field defaults, JCS-canonicalizes the complete `gpu_policy` structure, and measures its SHA-256 digest in a `gpu-policy` event. It then applies the basic settings and optional Rego policy before setting the GPU ready state. A false, undefined, malformed, or non-boolean Rego result stops boot before key provisioning. GPU-less launches return from the gate without measuring or evaluating a GPU policy. `gpu_policy` cannot be combined with `attest_gpu: false`. -Separate fail-closed `nvidia-smi` queries always require the current CC feature to be ON and require DevTools mode to be OFF unless the measured policy explicitly permits it.

CC must always be ON; DevTools must be OFF unless the measured policy explicitly permits it. The typed claim checks always require `measres == "success"`; by default they also require `dbgstat == "disabled"` and `secboot == true`, with the latter two checks controlled by their explicit opt-ins. Only after the default appraisal, typed claim checks, optional Rego policy, and per-device NVML checks succeed does dstack call `Device::set_confidential_compute_state(true)` to set the GPU ready state.

GPU-less launches return from the gate without measuring or evaluating a GPU policy. `gpu_policy` cannot be combined with `attest_gpu: false`. For every NVML-enumerated GPU, dstack calls `Device::is_cc_enabled()` and `Device::is_cc_dev_mode_enabled()` and requires the NVML device count to match the expected GPU count. CC must always be ON; DevTools must be OFF unless the measured policy explicitly permits it. The typed claim checks always require `measres == "success"`; by default they also require `dbgstat == "disabled"` and `secboot == true`, with the latter two checks controlled by their explicit opt-ins. Only after the default appraisal, typed claim checks, optional Rego policy, and per-device NVML checks succeed does dstack call `Device::set_confidential_compute_state(true)` to set the GPU ready state. The dstack CPU/guest boot chain is verified independently through measured boot; a GPU claim named `secboot` refers to the GPU appraisal, not UEFI Secure Boot in the CVM. ### Dual Attestation -GPU workloads require verification of both hardware components.

When the field is absent—including when `requirements` itself is absent—both parsing and measurement use the default empty object `{}`. Thus an omitted policy and an explicit `{}` have the same digest, while any explicitly present field, including an explicit default value, changes the digest. MrConfigV3 GPU launches also carry this digest as the optional `gpu_policy_hash` field; non-GPU launches omit it for compatibility. The guest requires and verifies the field when it observes an attached GPU, and requires it to be absent otherwise. The MrConfigV3 document is bound by TDX `MR_CONFIG_ID` or SEV-SNP `HOST_DATA`, so the host cannot substitute a different GPU policy without changing the platform launch identity. The typed policy used for enforcement applies omitted-field defaults and rejects unknown fields.

The typed claim checks always require `measres == "success"`; by default they also require `dbgstat == "disabled"` and `secboot == true`, with the latter two checks controlled by their explicit opt-ins. Only after the default appraisal, typed claim checks, optional Rego policy, and per-device NVML checks succeed does dstack call `Device::set_confidential_compute_state(true)` to set the GPU ready state.

The typed claim checks always require `measres == "success"`; by default they also require `dbgstat == "disabled"` and `secboot == true`, with the latter two checks controlled by their explicit opt-ins. Only after the default appraisal, typed claim checks, optional Rego policy, and per-device NVML checks succeed does dstack call `Device::set_confidential_compute_state(true)` to set the GPU ready state.

When the field is absent—including when `requirements` itself is absent—both parsing and measurement use the default empty object `{}`. Thus an omitted policy and an explicit `{}` have the same digest, while any explicitly present field, including an explicit default value, changes the digest. MrConfigV3 GPU launches also carry this digest as the optional `gpu_policy_hash` field; non-GPU launches omit it for compatibility. When the field is present, the guest compares it with the digest computed from app-compose; when it is absent, the guest skips this MrConfigV3 check. The MrConfigV3 document is bound by TDX `MR_CONFIG_ID` or SEV-SNP `HOST_DATA`, so the host cannot substitute a different GPU policy when this optional binding is present without changing the platform launch identity. The typed policy used for enforcement applies omitted-field defaults and rejects unknown fields. If GPU attestation is enabled and NVIDIA GPUs are present, dstack attests them and applies the basic settings and optional Rego policy before setting the GPU ready state. When no attestation claims are produced—because no GPU is attached or `gpu_policy.attest_gpu` is false—Rego is still evaluated with an empty array as `input` before any ready-state transition. This lets an application reject a launch whose attested GPU count is wrong. A false, undefined, malformed, or non-boolean Rego result stops boot before key provisioning. +The policy digest is remotely verifiable on each supported platform, but through different carriers: + +- **TDX:** `gpu-policy-hash` contains the raw 32-byte digest and is measured into RTMR3. Replay the event log and compare the result with the quote's RTMR3, then compare the event payload with the expected digest. When an MrConfigV3 document includes `gpu_policy_hash`, TDX `MR_CONFIG_ID` additionally binds that field. +- **AWS NitroTPM:** the same `gpu-policy-hash` event is extended into non-resettable SHA384 PCR14. Replay the PCR14 event chain against the signed NitroTPM Attestation Document, then compare the payload with the expected digest. +- **AMD SEV-SNP:** there is no quote-bound runtime event register in the current stack. Instead, GPU launches put the digest in optional `MrConfigV3.gpu_policy_hash`, and the signed SNP report's `HOST_DATA` binds the exact MrConfigV3 document. Verify the SNP report and `HOST_DATA` binding, then compare the field with the expected digest. If the optional field is absent, this check is not asserted. + For every NVML-enumerated GPU, dstack calls `Device::is_cc_enabled()` and `Device::is_cc_dev_mode_enabled()` and requires the NVML device count to match the expected GPU count. CC must always be ON; DevTools must be OFF unless the measured policy explicitly permits it. The typed claim checks always require `measres == "success"`; by default they also require `dbgstat == "disabled"` and `secboot == true`, with the latter two checks controlled by their explicit opt-ins. Only after the default appraisal, typed claim checks, optional Rego policy, and per-device NVML checks succeed does dstack call `Device::set_confidential_compute_state(true)` to set the GPU ready state. The dstack CPU/guest boot chain is verified independently through measured boot; a GPU claim named `secboot` refers to the GPU appraisal, not UEFI Secure Boot in the CVM. ### Dual Attestation GPU workloads require verification of both hardware components. The CPU TEE quote verifies the CVM and its measured guest code. NVIDIA-signed evidence, checked against NVIDIA RIMs and certificate status by `nvattest`, verifies the GPU appraisal. After the optional policy and ready-state operations succeed, dstack emits a `gpu-attestation` launch event before `system-ready`. Its versioned payload records the number of appraised devices, asserted CC/DevTools state, and SHA-256 of the complete nvattest JSON output (claims and detached EAT). On TDX, both `gpu-policy-hash` and `gpu-attestation` are append-only RTMR3 events; they are never derived from application-controlled `report_data`. +For a successful TDX GPU launch, the GPU-relevant RTMR3 event order is: + +```text +compose-hash +gpu-policy-hash +gpu-attestation +instance-id +boot-mr-done +``` + +`gpu-policy-hash` is emitted even for a GPU-less launch. `gpu-attestation` is emitted only after an attached GPU passes `nvattest`, the built-in checks, the optional Rego policy, and the NVML state checks.

To bind the API result to TDX evidence: verify the quote, replay the event log to the quote's RTMR3, require exactly one pre-`system-ready` `gpu-attestation` event, decode its JSON payload, and compare `evidence_sha256` with `SHA-256(UTF-8(GpuInfo.attestation))`. Only after this comparison should the verifier inspect the returned claims. This exact-byte comparison includes any whitespace or trailing newline in the returned string. + A verifier must replay the measured event log, require exactly one `gpu-policy-hash` event immediately after `compose-hash`, and compare its 32-byte payload with the expected policy digest (`SHA-256(JCS({}))` for the omitted/default policy). When MrConfigV3 includes `gpu_policy_hash`, it must match the same digest. When GPU protection is required, the verifier must also require exactly one pre-`system-ready` `gpu-attestation` event with `devices > 0` and, when applicable, the expected deployment count. The raw `attestation.out` file is not trusted by itself; if it is supplied for inspection, its digest must match the `gpu-attestation` event. ### GPU Threat Model and Lifetime diff --git a/docs/tutorials/attestation-verification.md b/docs/tutorials/attestation-verification.md index e39ab8ad0..63f4a6f22 100644 --- a/docs/tutorials/attestation-verification.md +++ b/docs/tutorials/attestation-verification.md @@ -518,6 +518,8 @@ These are the standard events you'll see in the log: | `system-preparing` | System initialization marker | Always present | | `app-id` | Application identifier | Should match your app name | | `compose-hash` | SHA-256 of docker compose config | Should match `tcb_info.compose_hash` | +| `gpu-policy-hash` | SHA-256 of the JCS-canonicalized GPU policy (default `{}`) | Should match the expected `requirements.gpu_policy` digest | +| `gpu-attestation` | Verified GPU state and digest of the boot-time `nvattest` JSON | Required for an attested GPU launch; verify as described below | | `instance-id` | Unique instance identifier | Should match `instance_id` from response | | `boot-mr-done` | Boot measurements complete | Marker event | | `mr-kms` | KMS identity measurement | KMS public key hash | @@ -526,6 +528,13 @@ These are the standard events you'll see in the log: | `storage-fs` | Storage filesystem type | Storage configuration | | `system-ready` | System ready marker | Always present at end | +For a successful GPU launch, the relevant order is `compose-hash`, +`gpu-policy-hash`, `gpu-attestation`, `instance-id`, and `boot-mr-done`. +After replaying the log to the quote's RTMR3, decode the JSON payload of +`gpu-attestation` and compare its `evidence_sha256` with the SHA-256 digest of +the exact UTF-8 `GpuInfo.attestation` string. `GpuInfo` reads the result saved +during boot and does not perform a new attestation. + ### Verify specific event values ```bash diff --git a/sdk/curl/api.md b/sdk/curl/api.md index a2b2d7ea0..6dccf75f2 100644 --- a/sdk/curl/api.md +++ b/sdk/curl/api.md @@ -306,6 +306,33 @@ curl --unix-socket /var/run/dstack.sock http://dstack/GpuInfo } ``` +`GpuInfo.attestation` is the exact UTF-8 `nvattest` output saved during boot; +calling this endpoint does not perform a new attestation.

The + per-request OCSP nonce is deliberately excluded from the key. +- `GET /v1/rim/` caches version-addressed NVIDIA RIM documents. +- `GET /healthz` reports process health. + +The proxy never signs or rewrites collateral. `nvattest` in the CVM still +verifies NVIDIA's certificate chains, OCSP signatures, response validity +window, RIM signatures, measurements, and the fresh GPU evidence nonce.

In +particular, `NV_ATTESTATION_SERVICE_KEY` supplies an optional NVIDIA bearer +token without placing it on the command line. + +Configure the VMM with a URL reachable during early guest boot: + +```toml +[cvm] +nvidia_attestation_proxy_url = "http://10.0.2.2:8090" +``` + +For QEMU user-mode networking, `10.0.2.2` is normally the host address. Other +networking modes should use the corresponding host or fleet service address. + +## Cache behavior + +On a cold miss the original request is forwarded to NVIDIA. A successful OCSP +response is cached no later than its signed `nextUpdate` and no longer than +`--ocsp-max-ttl` (24 hours by default). Responses without `nextUpdate` use one +hour from `thisUpdate`, matching the pinned NVIDIA SDK. RIM documents default +to a 30-day TTL. + +Expired entries are never served. Therefore a warm cache removes the NVIDIA +service from the boot path only for the signed validity period; it does not +turn revocation checking into an indefinite fail-open. Response headers expose +`X-Dstack-Cache: HIT|MISS`, `Age`, and `X-Dstack-Cache-Expires` for operations. +Each cache kind is capped at 10,000 entries by default; the oldest entry is +evicted when the limit is reached. Use `--max-cache-entries-per-kind` to tune +the bound for a deployment. + +Because a cached response contains the nonce from the request that populated +the cache, `nvattest` reports `x-nvidia-cert-ocsp-nonce-matches = false` on a +hit. When the proxy URL is configured, dstack selects NVIDIA's packaged +`allow_trust_outpost_ocsp.rego` policy. This relaxes only the OCSP nonce check; +the GPU attestation report's independent nonce remains required by dstack. diff --git a/dstack/gpu-attest-proxy/src/cache.rs b/dstack/gpu-attest-proxy/src/cache.rs new file mode 100644 index 000000000..8f166c7f5 --- /dev/null +++ b/dstack/gpu-attest-proxy/src/cache.rs @@ -0,0 +1,273 @@ +// SPDX-FileCopyrightText: © 2026 Phala Network +// +// SPDX-License-Identifier: Apache-2.0 + +use std::path::{Path, PathBuf};

The kernel config already enables ipset core, xt_set and most hash/bitmap set types as modules installed into the rootfs, but hash:netport was missing, causing `ipset save` to fail and kube-router to silently skip policy enforcement. Enable CONFIG_IP_SET_HASH_NETPORT=m and install the module into the rootfs image.

Pin 6.18.40 (current longterm, matching PREFERRED_VERSION_linux-yocto), delete both patches, and derive the kernel.org download path from the version instead of hardcoding v7.x. acceptance.sh now asserts the series against meta-dstack's distro conf so the skew cannot silently return. --- os/mkosi/README.md | 13 +- os/mkosi/components/kernel/kernel-build.sh | 2 +- os/mkosi/components/nvidia/nvidia-build.sh | 7 +- os/mkosi/components/nvidia/nvidia.sh | 3 +- ...01-linux-7.1-drop-legacy-of-gpio-api.patch | 37 - .../patches/0001-linux-6.19-7.1-compat.patch | 937 ------------------ os/mkosi/components/zfs/zfs-build.sh | 7 +- os/mkosi/components/zfs/zfs.sh | 1 - os/mkosi/tests/acceptance.sh | 14 +- os/mkosi/versions.env | 4 +- 10 files changed, 31 insertions(+), 994 deletions(-) delete mode 100644 os/mkosi/components/nvidia/patches/0001-linux-7.1-drop-legacy-of-gpio-api.patch delete mode 100644 os/mkosi/components/zfs/patches/0001-linux-6.19-7.1-compat.patch diff --git a/os/mkosi/README.md b/os/mkosi/README.md index 95b794284..704ff4033 100644 --- a/os/mkosi/README.md +++ b/os/mkosi/README.md @@ -6,10 +6,17 @@ target is functional parity with the Yocto image, not merely release archive compatibility. `parity.json` is the machine-checked inventory used by a build.

The new compile-time override used the same name with the incompatible "git:<20hex>" display form and validated nothing, so a Yocto repro build started from a shell that had already exported the variable could bake a bare SHA into every binary -- changing Info.rev for anything matching the "git:" prefix, and with it the rootfs hash. Nothing protected against this except BitBake incidentally filtering the variable out of recipe environments.

Verified with dosfstools 4.2 / mtools 4.0.43: TZ=UTC and TZ=America/Los_Angeles differ at byte 80944. Clamp the epoch to the FAT epoch and pin TZ=UTC for the ESP construction. disk.raw is now genuinely reproducible, so add it to the Yocto repro-build whitelist, where it had been excluded as a known non-reproducible artifact.

Any package a future Packages= line pulls in, directly or as a dependency, would run at boot inside the CVM with no diff to the preset file. Adds a terminal 99-dstack-default.preset with 'disable *' so the enable list is exhaustive and auditable. Also moves 'enable dstack-tee-simulator.service' into a dev-profile skeleton. It shipped unconditionally in the production skeleton, inert only because the unit is installed for dev alone -- a guard independent of the preset. A production image serving synthetic TDX quotes attests successfully while providing no hardware guarantee. normalize-skeleton-modes.sh now covers profile skeletons too, guards the directory loop like the file loop, and skips the skeleton root itself, which it was chmod'ing as a side effect of an empty relative path. --- os/mkosi/mkosi.finalize | 2 +- .../system-preset/85-dstack-dev.preset | 7 +++ .../systemd/system-preset/80-dstack.preset | 1 - .../system-preset/99-dstack-default.preset | 12 +++++ os/mkosi/scripts/normalize-skeleton-modes.sh | 50 ++++++++++++------- os/mkosi/tests/acceptance.sh | 18 +++++++ 6 files changed, 70 insertions(+), 20 deletions(-) create mode 100644 os/mkosi/mkosi.profiles/dev/mkosi.skeleton/usr/lib/systemd/system-preset/85-dstack-dev.preset create mode 100644 os/mkosi/mkosi.skeleton/usr/lib/systemd/system-preset/99-dstack-default.preset diff --git a/os/mkosi/mkosi.finalize b/os/mkosi/mkosi.finalize index 5f78ec095..e650edde0 100755 --- a/os/mkosi/mkosi.finalize +++ b/os/mkosi/mkosi.finalize @@ -10,7 +10,7 @@ WORK="$OUTPUTDIR/.dstack-$FLAVOR" KSTAGE="$WORK/kernel-stage" ARTIFACTS="$WORK/artifacts" -"$SELF/scripts/normalize-skeleton-modes.sh" "$TREE" +"$SELF/scripts/normalize-skeleton-modes.sh" "$TREE" "$FLAVOR" mkdir -p "$KSTAGE/usr/lib" "$OUTPUTDIR/.image-tools" cp -a "$TREE/usr/lib/modules" "$KSTAGE/usr/lib/" install -m0644 "$TREE/usr/lib/dstack/firmware/ovmf.fd" "$KSTAGE/ovmf.fd" diff --git a/os/mkosi/mkosi.profiles/dev/mkosi.skeleton/usr/lib/systemd/system-preset/85-dstack-dev.preset b/os/mkosi/mkosi.profiles/dev/mkosi.skeleton/usr/lib/systemd/system-preset/85-dstack-dev.preset new file mode 100644 index 000000000..9bc443316 --- /dev/null +++ b/os/mkosi/mkosi.profiles/dev/mkosi.skeleton/usr/lib/systemd/system-preset/85-dstack-dev.preset @@ -0,0 +1,7 @@ +# SPDX-License-Identifier: Apache-2.0 +# +# Development-only units.

The compiler that actually produced nvidia-ctk and nvidia-container-runtime was therefore neither checksum-verified nor part of any component cache key, and the build could not run at all with GOTOOLCHAIN=local or without proxy access. Bump the pinned toolchain to 1.25.12, which satisfies that requirement and still builds the sysbox modules that declare go 1.22, and set GOTOOLCHAIN=local so a future go.mod bump fails loudly instead of silently fetching a different compiler. Also verify toolchain downloads before publishing them under the cached name.

It was replaced by an ad-hoc sed that only reproduced the -Werror overrides and dropped the prefix map entirely. 0005-UefiCpuPkg backports edk2 9ccf8751 for NASM 3.x. The recipe records that stable202502 must be kept for the pre202505 measurement layout and does not assemble with NASM 3.x without this, so the next snapshot bump carrying nasm 3.x would have turned the build into a hard failure with the fix sitting unused in-tree. The encoding is unchanged on NASM 2.x, so applying it also brings this build closer to the production one. NASM_PREFIX_MAP stays empty: Yocto carries a nasm patch adding --debug-prefix-map, and the Debian snapshot ships stock nasm, which rejects the option (confirmed against nasm 2.16.01). The revision also moves to versions.env as OVMF_REVISION -- it was the only component pin hardcoded in a build script -- and acceptance.sh now reads SRCREV out of the recipe instead of restating the hash, which would have happily pinned a stale value after a Yocto bump. --- os/mkosi/components/ovmf/ovmf-build.sh | 36 ++++++++++++++++++++------ os/mkosi/components/ovmf/ovmf.sh | 3 +++ os/mkosi/tests/acceptance.sh | 16 +++++++++++- os/mkosi/versions.env | 3 +++ 4 files changed, 49 insertions(+), 9 deletions(-) diff --git a/os/mkosi/components/ovmf/ovmf-build.sh b/os/mkosi/components/ovmf/ovmf-build.sh index 6a4a16b94..fa9dd2732 100755 --- a/os/mkosi/components/ovmf/ovmf-build.sh +++ b/os/mkosi/components/ovmf/ovmf-build.sh @@ -4,13 +4,15 @@ # stock distro OVMF is not compatible with dstack's TDX measurement format. set -euo pipefail ROOT=$(cd "$(dirname "${BASH_SOURCE[0]}")/../../../.." && pwd) +# shellcheck source=/dev/null +source "$ROOT/os/mkosi/versions.env" BUILD_DIR=${1:?build directory required} OUT=${2:?output file required} SEV_OUT=${3:?SEV output file required} BUILD_DIR=$(realpath -m "$BUILD_DIR") OUT=$(realpath -m "$OUT") SEV_OUT=$(realpath -m "$SEV_OUT") -REV=fbe0805b2091393406952e84724188f8c1941837 +REV=${OVMF_REVISION:?OVMF_REVISION required} src="$BUILD_DIR/edk2" if [[ ! -d $src/.git ]]; then mkdir -p "$BUILD_DIR" @@ -28,20 +30,38 @@ for attempt in 1 2 3; do sleep $((attempt * 5)) done git -C "$src" reset -q --hard "$REV" -patch -d "$src" -p1 --forward --fuzz=0 < \ - "$ROOT/os/yocto/layers/meta-dstack/recipes-core/dstack-ovmf/dstack-ovmf/0004-Reproduciable.patch" -patch -d "$src" -p1 --forward --fuzz=0 < \ - "$ROOT/os/yocto/layers/meta-dstack/recipes-core/dstack-ovmf/dstack-ovmf/0006-OvmfPkg-AmdSev-drop-embedded-grub.patch" +# Same patch set as meta-dstack's dstack-ovmf_git.bb, minus 0001/0002 which +# only adapt BaseTools to bitbake's native-tooling layout. +# +# 0003 threads ENV(GCC_PREFIX_MAP)/ENV(NASM_PREFIX_MAP) into the tool +# definitions, which is how the warning overrides and the debug prefix +# map reach the compiler. +# 0005 backports edk2 9ccf8751 (push dword -> push qword). stable202502 does +# not assemble with NASM 3.x without it, and the recipe comment records +# that this pin must be kept for the pre202505 measurement layout.

Output= shared the release name, so mkosi tracked assemble.sh's release tarball as one of its own outputs -- something clean and --force are entitled to delete -- and mkosi.postoutput had to delete mkosi's convenience symlink by hand. Give mkosi a name of its own, skip compressing an artifact that is discarded anyway, and drop it explicitly in the staging directory before it is promoted. That also fixes the dev flavor leaving a full unmeasured Debian rootfs tar beside the release, which only the prod name collision had hidden. %i and %v expand in file order, so ImageId/ImageVersion now precede Output=; declaring Output first silently yields "--rootfs.tar". acceptance.sh checks both the ordering and that ImageVersion matches DSTACK_VERSION. mkosi.skeleton/etc/apt/apt.conf.d/99dstack-reproducible was dead: mkosi runs apt from outside the image, so per its own manual a package manager config supplied via SkeletonTrees= never takes effect, and it passes these as -o options which outrank config files anyway. All three settings are already covered natively by Snapshot= and WithRecommends=. SkeletonTrees= and PostInstallationScripts= restated mkosi's auto-discovery and made the skeleton mount twice. Bootloader= is unreachable with Bootable=no, SecureBoot=no is the default, and SplitArtifacts= only gates UKI/kernel paths that Bootable=no already disables. KernelCommandLine= was dead for the same reason and contradicted the command line actually measured into the UKI (panic=30 vs panic=1, a console=tty0 that cannot work with CONFIG_VT=n, and none of the hardening tokens). mkosi clean ran without the build's --output-directory, so mkosi.clean was removing from os/mkosi/ rather than the build tree. Also records why the manual depmod plus mtime normalization is load-bearing for repro-check: it is what keeps mkosi's own nondeterministic depmod from firing. --- os/mkosi/build.sh | 6 +++- os/mkosi/mkosi.build | 6 ++++ os/mkosi/mkosi.conf | 30 +++++++++++-------- os/mkosi/mkosi.postoutput | 12 +++++--- .../etc/apt/apt.conf.d/99dstack-reproducible | 3 -- os/mkosi/tests/acceptance.sh | 18 ++++++++--- 6 files changed, 51 insertions(+), 24 deletions(-) delete mode 100644 os/mkosi/mkosi.skeleton/etc/apt/apt.conf.d/99dstack-reproducible diff --git a/os/mkosi/build.sh b/os/mkosi/build.sh index d676b75a5..8506ff2c2 100755 --- a/os/mkosi/build.sh +++ b/os/mkosi/build.sh @@ -31,7 +31,11 @@ export TZ=UTC LC_ALL=C # snapshot, then shares that read-only environment across all requested flavors # or both legs of repro-check. if [[ $action != dev-image ]]; then - mkosi --directory "$SELF" clean -f + # --directory only chdirs, and no OutputDirectory= is configured, so without + # the same --output-directory the build uses, mkosi.clean would run its + # removal against os/mkosi/ instead of the build tree. + mkdir -p "$BUILD_DIR/out" + mkosi --directory "$SELF" --output-directory="$BUILD_DIR/out" clean -f fi build_one() { diff --git a/os/mkosi/mkosi.build b/os/mkosi/mkosi.build index 440df9757..739956c9b 100755 --- a/os/mkosi/mkosi.build +++ b/os/mkosi/mkosi.build @@ -70,6 +70,12 @@ done "$SELF/scripts/merge-component-trees.py" "$DESTDIR" \ "kernel=$kernel_stage" ln -sfn usr/lib "$DESTDIR/lib" +# Run depmod ourselves and then normalize mtimes below. mkosi's own run_depmod +# is nondeterministic, and it skips a kernel directory only when all four +# outputs exist and every *.ko* mtime is <= modules.dep's.

Refuse to build from a dirty worktree, with DSTACK_ALLOW_DIRTY=1 to opt in and record -modified instead. sysbox checkouts never ran git clean -qfdx, unlike every other component, so a revision bump in an existing work directory carried the previous vendor/ tree and the copied-in generated protobuf sources into the new binaries. Its subuid/subgid writes also appended to a reused staging tree, accumulating duplicate entries that some userns tooling treats as a parse error. nvattest builds in a fixed path under a world-writable parent; flock serializes but does not establish ownership. Create the directory instead of adopting it, so a leftover or attacker-created tree aborts the build. component_run's bare assertions killed the whole build with no output when a component descriptor was malformed; they now say which file and which symbol. The sshd drop-in restores PermitEmptyPasswords and PubkeyAuthentication from meta-dstack's version. Both match sshd's compiled defaults, but this file is the image's only ssh policy and should not depend on them. write-source-manifest.py uses env python3 like every other script; build.sh invokes it directly, so the absolute path broke on hosts without /usr/bin/python3. --- os/mkosi/build.sh | 18 +++++++++++++++++- os/mkosi/components/nvattest/nvattest-build.sh | 7 ++++++- os/mkosi/components/sysbox/sysbox-build.sh | 13 ++++++++++--- .../etc/ssh/sshd_config.d/10-dstack.conf | 10 ++++++++++ os/mkosi/scripts/component-framework.sh | 15 ++++++++++++--- os/mkosi/scripts/write-source-manifest.py | 2 +- 6 files changed, 56 insertions(+), 9 deletions(-) diff --git a/os/mkosi/build.sh b/os/mkosi/build.sh index 8506ff2c2..552b9b57b 100755 --- a/os/mkosi/build.sh +++ b/os/mkosi/build.sh @@ -22,10 +22,26 @@ actual=$(mkosi --version | awk '{print $2}' | cut -d. -f1) } export SOURCE_DATE_EPOCH=${SOURCE_DATE_EPOCH:-$(git -C "$ROOT" log -1 --format=%ct)} revision=$(git -C "$ROOT" rev-parse HEAD) +# BuildSources= mounts and compiles the working tree, not HEAD, so without this +# an uncommitted change would produce an image whose guest agent and measured +# metadata.json both report a clean upstream revision. git_revision! marks this +# the same way when it derives the value itself. +dirty= +if ! git -C "$ROOT" diff --quiet HEAD -- || \ + [[ -n $(git -C "$ROOT" ls-files --others --exclude-standard) ]]; then + if [[ ${DSTACK_ALLOW_DIRTY:-0} != 1 ]]; then + echo "refusing to build from a dirty worktree: the recorded revision would" >&2 + echo "not describe the sources being compiled.

It was also workflow_dispatch-only, so no PR or push exercised os/mkosi at all. Add a static job that runs build.sh lint on every PR and master push touching os/. It finishes in seconds and covers the whole static contract, which is where the useful per-change signal is; the ~40 minute image build stays opt-in behind workflow_dispatch. The baseline hashes embed the revision they were produced from, so the comparison now runs only when the built commit is that revision and prints an actionable notice otherwise, instead of comparing against values that cannot match. Also makes the release-member checks assert something: they piped sha256sum.txt and metadata.json to stdout without inspecting them. The DSTACK_DEV_CACHE_DIR check was vacuous since the workflow never sets it, and the run blocks now use set -euo pipefail. --- .github/workflows/mkosi-build.yml | 65 +++++++++++++++++++++++++------ 1 file changed, 53 insertions(+), 12 deletions(-) diff --git a/.github/workflows/mkosi-build.yml b/.github/workflows/mkosi-build.yml index 6a077f675..f35ce5673 100644 --- a/.github/workflows/mkosi-build.yml +++ b/.github/workflows/mkosi-build.yml @@ -6,22 +6,47 @@ name: Verify mkosi reproducibility on: workflow_dispatch: + pull_request: + paths: + - 'os/**' + - '.github/workflows/mkosi-build.yml' + push: + branches: [master] + paths: + - 'os/**' + - '.github/workflows/mkosi-build.yml' concurrency: group: mkosi-build-${{ github.ref }} cancel-in-progress: true env: - # These values were produced by two cache-disabled local builds.

Three of the four assertions came from meta-dstack fragments that are silently ineffective there, because Yocto warns on an unsatisfied fragment line instead of failing: HOTPLUG_CPU=n is "def_bool y depends on SMP" on x86, so it cannot be turned off while SMP is on. BLK_DEV_THROTTLING_LOW=y no longer exists; the symbol was removed upstream. BRIDGE_NF_EBTABLES=y depends on BRIDGE, which is a module in both builds, so only =m is reachable. Restores the original value. The fourth is a real gap that had to be closed rather than dropped: DEBUG_FS=n is required by the production hardening audit, but x86_64_defconfig enables BLK_DEV_IO_TRACE, which selects DEBUG_FS. blktrace has no role in a production guest, so disable it. Checked every symbol that selects DEBUG_FS in this kernel; it is the only one defconfig enables. Verified by generating the real .config from linux-6.18.40 with defconfig plus this fragment: the gate passes and KEXEC, KEXEC_FILE, HIBERNATION, DEBUG_FS, PROC_KCORE, PM, SUSPEND and BLK_DEV_IO_TRACE are all off with STRICT_DEVMEM on.

Make it the mkosi backend's release path, mirroring guest-os.yml for the Yocto backend. Publishing is bound to the tag: pushing mkosi-os-v is the only event that creates a GitHub Release, so a workflow_dispatch dry run cannot be mistaken for one. The push trigger deliberately carries no paths filter, because GitHub ANDs path and ref filters and would silently drop a release tag placed on a commit that does not touch os/**. Report the hashes operators actually need, led by os_image_hash: the log gets a ::notice, the job summary a table plus the sha256sum.txt preimage and metadata.json, and image-hashes.txt ships as a release asset. The values are read back out of the published tarball rather than the staging tree, and digest.txt is recomputed from sha256sum.txt and cross-checked against the UKI package, so a corrupt release fails the build instead of being published. The release job rejects a tag whose version disagrees with versions.env or whose measured metadata.json records a different git revision than the tagged commit, which also catches a dirty-worktree build. Replace the rotting baselines with build.sh repro-check, available as an opt-in dispatch input: two legs, differing job counts, byte-for-byte comparison, no hash to keep refreshing. --- .github/workflows/mkosi-build.yml | 314 +++++++++++++++++++++++++----- 1 file changed, 266 insertions(+), 48 deletions(-) diff --git a/.github/workflows/mkosi-build.yml b/.github/workflows/mkosi-build.yml index f35ce5673..600699e2f 100644 --- a/.github/workflows/mkosi-build.yml +++ b/.github/workflows/mkosi-build.yml @@ -2,32 +2,36 @@ # # SPDX-License-Identifier: Apache-2.0 -name: Verify mkosi reproducibility +name: Build Guest Images (mkosi) +# Publishing is bound to the tag, not to a workflow input: pushing +# mkosi-os-v is the only event that creates a GitHub Release.

Building therefore meant installing the right mkosi on the host, and CI pinned a revision that nothing else shared. Add os/mkosi/repro-build/, modelled on the Yocto backend's container, so a build needs only Docker and the privileges mkosi requires for loop devices, device-mapper and mounts. The base image is pinned by digest and the mkosi revision now lives in versions.env, which CI reads too, so the container and CI can no longer drift onto different mkosi builds. Two details the Yocto container does not face, because it runs as the caller while this one must run as root: - git refuses a tree owned by another user, so safe.directory is passed through the environment instead of writing to the caller's config. - In a git worktree .git points outside the source mount, so the common git directory is bind-mounted at its own path and build.sh can still derive SOURCE_DATE_EPOCH and the measured revision. The entrypoint checks the image against `mkosi dependencies` before starting, so a mkosi that grew a requirement fails in seconds with the package name rather than partway through a 40-minute build, and hands the artifacts back to the caller's uid on the way out, including after a failure. --- .github/workflows/mkosi-build.yml | 7 +- Makefile | 12 ++- os/mkosi/.gitignore | 2 + os/mkosi/README.md | 12 +++ os/mkosi/repro-build/.gitignore | 1 + os/mkosi/repro-build/Dockerfile.repro | 77 ++++++++++++++ os/mkosi/repro-build/entrypoint.sh | 51 +++++++++ os/mkosi/repro-build/repro-build.sh | 143 ++++++++++++++++++++++++++ os/mkosi/versions.env | 5 + 9 files changed, 308 insertions(+), 2 deletions(-) create mode 100644 os/mkosi/repro-build/.gitignore create mode 100644 os/mkosi/repro-build/Dockerfile.repro create mode 100755 os/mkosi/repro-build/entrypoint.sh create mode 100755 os/mkosi/repro-build/repro-build.sh diff --git a/.github/workflows/mkosi-build.yml b/.github/workflows/mkosi-build.yml index 600699e2f..fe9d9abfb 100644 --- a/.github/workflows/mkosi-build.yml +++ b/.github/workflows/mkosi-build.yml @@ -95,9 +95,14 @@ jobs: - name: Install pinned mkosi run: | + set -euo pipefail + # Take the revision from versions.env so CI and the container builder + # in os/mkosi/repro-build cannot drift onto different mkosi builds. + # shellcheck source=/dev/null + source os/mkosi/versions.env python3 -m venv "$RUNNER_TEMP/mkosi-venv" "$RUNNER_TEMP/mkosi-venv/bin/pip" install --disable-pip-version-check \ - 'mkosi @ git+https://github.com/systemd/mkosi.git@84af20892b61c8e177e391f997ded8b4cb5514f2' + "mkosi @ git+https://github.com/systemd/mkosi.git@${MKOSI_REVISION}" echo "$RUNNER_TEMP/mkosi-venv/bin" >> "$GITHUB_PATH" - name: Install mkosi host dependencies diff --git a/Makefile b/Makefile index f51b05896..30b2cc777 100644 --- a/Makefile +++ b/Makefile @@ -12,7 +12,8 @@ OS_YOCTO_SUBMODULES := \ os/yocto/deps/meta-rust-bin \ os/yocto/deps/meta-security -.PHONY: help core core-check core-test sdk-test os os-yocto os-deps os-image os-repro-check +.PHONY: help core core-check core-test sdk-test os os-yocto os-deps os-image os-repro-check \ + os-image-mkosi os-repro-check-mkosi help: @echo "dstack monorepo targets:" @@ -25,6 +26,8 @@ help: @echo " os-deps initialize only the Yocto dependency submodules" @echo " os-image build one production guest image in the pinned container" @echo " os-repro-check build twice and compare reproducible outputs" + @echo " os-image-mkosi build one production guest image with the mkosi backend" + @echo " os-repro-check-mkosi build twice with mkosi and compare outputs" core: cargo build --manifest-path dstack/Cargo.toml @@ -52,3 +55,10 @@ os-image: os-deps os-repro-check: os-deps cd os/yocto/repro-build && ./repro-build.sh + +# The mkosi backend vendors no submodules, so these do not depend on os-deps. +os-image-mkosi: + ./os/mkosi/repro-build/repro-build.sh + +os-repro-check-mkosi: + ./os/mkosi/repro-build/repro-build.sh -c diff --git a/os/mkosi/.gitignore b/os/mkosi/.gitignore index 09198f6df..4014b1892 100644 --- a/os/mkosi/.gitignore +++ b/os/mkosi/.gitignore @@ -1,5 +1,7 @@ build*/ repro*/ +# The container build environment, not a build output the globs above target. +!repro-build/ *.raw *.raw.zst mkosi.tools/ diff --git a/os/mkosi/README.md b/os/mkosi/README.md index 1ed4dc48e..54db92273 100644 --- a/os/mkosi/README.md +++ b/os/mkosi/README.md @@ -53,6 +53,18 @@ headers.

The handshake still runs in rustls; afterwards the negotiated keys are installed into the kernel TLS ULP so record crypto happens there, and when combined with tcp_splice_enabled the payload is relayed with splice and never enters userspace. Measured on a dedicated 44-vCPU GCP VM with the gateway pinned to 4 cores (isolated A/B, interleaved rounds): rustls (userspace) 32226 CPS 7.69 GB/s kTLS alone 20598 CPS 5.72 GB/s (-36% / -26%) kTLS + splice 22640 CPS 9.63 GB/s (-30% / +25%) kTLS alone is a loss: without NIC TLS offload (TlsTxDevice = 0) the kernel's software AES-GCM is slower than rustls with aws-lc-rs, plus per-connection setup cost. Combined with splice it gives the highest terminate throughput measured, so it is worth having for bulk-transfer deployments -- but it stays off by default because connection setup rate drops ~30%. Security note: enabling this extracts session keys into the kernel via dangerous_extract_secrets. Inside a CVM the kernel is part of the measured TCB; on a normal host this widens key exposure. Hence opt-in.

Offloading at handshake time therefore penalises short request/response connections that never earn it back. With the new proxy.ktls_offload_after_bytes, a connection starts in userspace rustls and is handed to the kernel only once it has moved that many bytes: flush, let CorkStream stop at a TLS record boundary, extract the current traffic secrets (they carry the record sequence numbers, which is what makes a mid-stream handover sound), install them into the kernel, splice the rest. 0 keeps the previous immediate-offload behaviour.

The cause was scheduling, not the data path: the gateway performed ~0.617 context switches per request against HAProxy's ~0.000. Two sources, both structural: * accept runs on its own current_thread runtime and hands every connection to a separate multi-threaded worker runtime -- one cross-runtime wakeup per connection; * tokio's work-stealing scheduler then migrates those tasks between worker threads, costing further wakeups and cache locality. With proxy.thread_per_core = true the proxy instead runs `workers` threads, each with its own current_thread runtime and its own SO_REUSEPORT listener. The kernel load-balances new connections across the listeners and a connection is accepted and served entirely on one thread, so nothing is handed off. Measured on a dedicated 44-vCPU GCP VM, 4 cores, vs the default model and vs HAProxy given matching settings: default thread-per-core HAProxy terminate small-req 158k @3.55 267k @4.03 204k @4.03 terminate CPS 32.8k @3.65 45.0k @3.96 28.2k @4.00 passthrough small-req 175k @3.56 312k @4.02 355k @4.02 terminate throughput 7.5 GB/s 8.3 GB/s 6.0 GB/s Context switches per request drop to ~0.000 and the proxy now saturates its cores. That turns two of the three deficits against HAProxy into wins (terminate small-request +31%, terminate CPS +60%) and closes most of the third (passthrough small-request now -12%, was -63%). Off by default: it changes the process model, needs SO_REUSEPORT (Linux), and per-core accept queues mean a slow connection can only be served by the core that accepted it.

Measured on the 4-core GCP bed (passthrough): pipe2 per connection 1.00 -> 0.00 connection-setup CPU 132.4 -> 120.1 us median (HAProxy 123.4) That closes the last connection-setup deficit against HAProxy; the two now overlap within run-to-run spread. Re-verified with repeated 100 MiB checksum round-trips and interleaved small/large requests, which is what a dirty pooled pipe would corrupt. --- dstack/gateway/src/proxy/splice.rs | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-) diff --git a/dstack/gateway/src/proxy/splice.rs b/dstack/gateway/src/proxy/splice.rs index 8e2c47205..2653ba4be 100644 --- a/dstack/gateway/src/proxy/splice.rs +++ b/dstack/gateway/src/proxy/splice.rs @@ -72,7 +72,7 @@ impl PooledPipe { return Ok(Self { rd: Some(rd), wr: Some(wr), - drained: false, + drained: true, }); } let (rd, wr) = pipe().context("failed to create splice pipe")?; @@ -80,7 +80,7 @@ impl PooledPipe { Ok(Self { rd: Some(rd), wr: Some(wr), - drained: false, + drained: true, }) } @@ -137,11 +137,10 @@ async fn splice_one(src: Arc, dst: Arc) -> Result<()> { } }; if n == 0 { - // Source is at EOF and every chunk was fully drained below, so the - // pipe is empty and safe to reuse. - pipe.drained = true; - break; + break; // EOF on source; the pipe was left empty by the last drain } + // A chunk is in the pipe now: not safe to recycle until fully drained. + pipe.drained = false; // Drain the pipe fully into the destination socket. let mut left = n; @@ -158,7 +157,14 @@ async fn splice_one(src: Arc, dst: Arc) -> Result<()> { ) .map_err(errno_to_io) }) { - Ok(m) => left -= m, + Ok(m) => { + left -= m; + if left == 0 { + // Fully drained: the pipe is empty again, so it can go + // back to the pool even if the connection dies next. + pipe.drained = true; + } + } Err(ref e) if e.kind() == std::io::ErrorKind::WouldBlock => continue, Err(e) => return Err(e).context("splice pipe->dst failed"), } From 3235eeba24168077bfdf65234ad67dff15352b41 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Sat, 25 Jul 2026 00:04:33 -0700 Subject: [PATCH 0317/1246] perf(gateway): engage splice only after a traffic threshold splice costs ~17 syscalls per connection to move a small response -- fill the pipe, drain the pipe, plus readiness retries -- where a read/write pair needs two. Its benefit is per byte but its cost is per connection, the same shape as kTLS, so short request/response connections paid for zero-copy they never used. With the new proxy.tcp_splice_after_bytes a passthrough connection is relayed with plain reads/writes until it has moved that many bytes, then switches to splice for the remainder. 0 keeps the previous behaviour. The relay buffers come from a thread-local pool for the same reason the pipes do: a first cut that allocated two buffer_size buffers per connection was *worse* than the pipe setup it replaced (148.6 us vs 133.5 us per connection). Pooled, and sized for this phase rather than for bulk copying, it wins. Measured on the 4-core GCP bed (passthrough, medians of 3 interleaved rounds, threshold 64 KiB): always splice adaptive HAProxy connection setup 123.0 us 117.2 us 123.5 us small-request rate 300.0k rps 295.3k rps 344.6k rps bulk throughput 12.6 GB/s 12.4 GB/s 10.2 GB/s splice syscalls per connection drop from 16.86 to 0.00 on the connection-churn workload, and connection setup costs slightly less CPU than HAProxy. Keep-alive and bulk traffic are unchanged within run-to-run spread (~2%), since those connections cross the threshold and end up spliced anyway. Verified with checksum round-trips at 1 MiB and 100 MiB plus payloads sized just under and just over the threshold, which is where the handover happens. --- dstack/gateway/gateway.toml | 2 + dstack/gateway/src/config.rs | 10 ++ dstack/gateway/src/proxy/splice.rs | 125 ++++++++++++++++++++- dstack/gateway/src/proxy/tls_passthough.rs | 14 ++- 4 files changed, 147 insertions(+), 4 deletions(-) diff --git a/dstack/gateway/gateway.toml b/dstack/gateway/gateway.toml index b359122c8..6097305a9 100644 --- a/dstack/gateway/gateway.toml +++ b/dstack/gateway/gateway.toml @@ -95,6 +95,8 @@ inbound_pp_enabled = false # Bulk throughput +~12%, but small-request latency regresses.

The only thing holding it back was that it had never run longer than a benchmark. A soak of 8 x 60s of mixed load (small-request, bulk, connection-churn) says it is stable: RSS 21.9 MB cold -> ~44 MB steady, flat across all rounds fds 31 -> 543, plateauing at the pipe pool cap, then flat threads 11, constant drift small-request -2.3%, connection rate -1.3% (both within noise) Flipping the default needs a safety net, because the model cannot work without SO_REUSEPORT and failing to serve is much worse than losing the optimisation. `start` now probes a SO_REUSEPORT bind first and falls back to the shared-runtime proxy with a warning if it fails. Verified by occupying the port with a non-REUSEPORT socket: the gateway logs the fallback and keeps serving. Deployments that want the old process model can still set proxy.thread_per_core = false.

Passthrough always has a plain socket on both sides, so it can use `TcpStream::split`, which hands out borrowed halves with no lock. Added `bridge_tcp` for that case. * every read, write and flush was wrapped in `tokio::time::timeout`, i.e. three timer arm/disarm pairs per request; `TimerEntry` drop plus poll_elapsed came to 2.9%. Replaced with one watchdog per connection that samples per-direction progress counters -- the hot path now costs an integer increment instead of touching the timer wheel, and no clock is read. The watchdog is coarser than the old per-operation timeouts: it fires within `idle/4`, so a stalled connection is closed in up to 1.25x `idle` rather than exactly at it. Verified with `idle = 3s`: old path closed at 3.0s, new at 3.7s.

Bind them all up front instead and hand listener i to worker i: the setup leaves the per-thread path, and group order becomes ours. That order matters for anything that steers connections by listener index, which is what motivated this. Recording the result of that attempt here, because it was a dead end worth not repeating: SO_REUSEPORT's default 4-tuple hash distributes moderate numbers of long-lived connections unevenly, and thread-per-core cannot rebalance afterwards. At 16 connections over 4 cores the per-core utilisation came out like [99, 42, 101, 101] and throughput swung 46% between restarts purely on how the hash fell. SO_ATTACH_REUSEPORT_CBPF was tried to replace the hash. Classic BPF has no maps, so round-robin is not expressible; the only useful signal it exposes is the CPU handling the packet, so the program steered by `cpu % n`. Measured over 6 restarts each at 16 connections: default hash 245 539 rps 4.0 of 4 cores active lowest core 73% cpu steering 167 331 rps 2.3 of 4 cores active lowest core 100% It collapses the distribution instead of evening it out: connections are established in a burst, so only the one or two client CPUs live at that moment get sampled, and every connection lands on the same one or two listeners. The knob was removed rather than shipped -- a setting that costs 32% in the only scenario measured is worse than no setting. A real fix needs per-connection state, i.e. SO_ATTACH_REUSEPORT_EBPF with a counter map, or accepting from a shared queue as HAProxy does. --- dstack/Cargo.lock | 1 + dstack/gateway/Cargo.toml | 1 + dstack/gateway/src/proxy.rs | 29 +++++++++++++- dstack/gateway/src/proxy/reuseport.rs | 58 +++++++++++++++++++++++++++ 4 files changed, 87 insertions(+), 2 deletions(-) create mode 100644 dstack/gateway/src/proxy/reuseport.rs diff --git a/dstack/Cargo.lock b/dstack/Cargo.lock index dcec54791..3687e67c9 100644 --- a/dstack/Cargo.lock +++ b/dstack/Cargo.lock @@ -1888,6 +1888,7 @@ dependencies = [ "ipnet", "jemallocator", "ktls", + "libc", "load_config", "nix 0.29.0", "or-panic", diff --git a/dstack/gateway/Cargo.toml b/dstack/gateway/Cargo.toml index 9629ba3d0..34ce64728 100644 --- a/dstack/gateway/Cargo.toml +++ b/dstack/gateway/Cargo.toml @@ -69,6 +69,7 @@ cached-cell.workspace = true [target.'cfg(unix)'.dependencies] nix = { workspace = true, features = ["resource", "fs", "socket", "zerocopy"] } ktls.workspace = true +libc.workspace = true socket2.workspace = true [[bin]] diff --git a/dstack/gateway/src/proxy.rs b/dstack/gateway/src/proxy.rs index 96f3b161a..3f98f8f14 100644 --- a/dstack/gateway/src/proxy.rs +++ b/dstack/gateway/src/proxy.rs @@ -45,6 +45,7 @@ pub(crate) type AddressGroup = smallvec::SmallVec<[AddressInfo; 4]>; mod adaptive_ktls; mod io_bridge; pub(crate) mod port_policy; +mod reuseport; mod sni; mod splice; mod tls_passthough; @@ -389,8 +390,26 @@ fn probe_reuse_port(config: &ProxyConfig) -> Result<()> { /// in the default model. fn start_thread_per_core(config: ProxyConfig, app_state: Proxy) -> Result<()> { let workers = config.workers.max(1); + // Bind every listener here, in order, rather than letting each thread bind + // its own: the reuseport steering program selects a socket by its position + // in the group, so the order has to be ours to control. + let mut per_worker: Vec> = + (0..workers).map(|_| Vec::new()).collect(); + for &port in &config.listen_port { + let addr = std::net::SocketAddr::from((config.listen_addr, port)); + let group = reuseport::bind_group(addr, workers, LISTEN_BACKLOG) + .with_context(|| format!("failed to bind reuseport group on {addr}"))?; + info!( + "tcp bridge listening on {}:{} across {} listeners", + config.listen_addr, port, workers + ); + for (i, l) in group.into_iter().enumerate() { + per_worker[i].push(l); + } + } + let config = Arc::new(config); - for i in 0..workers { + for (i, std_listeners) in per_worker.into_iter().enumerate() { let config = config.clone(); let app_state = app_state.clone(); std::thread::Builder::new() @@ -401,7 +420,13 @@ fn start_thread_per_core(config: ProxyConfig, app_state: Proxy) -> Result<()> { .build() .or_panic("Failed to build Tokio runtime"); let result = rt.block_on(async { - let listeners = bind_listeners(&config, true).await?; + let mut listeners = Vec::with_capacity(std_listeners.len()); + for l in std_listeners { + listeners.push( + TcpListener::from_std(l) + .context("failed to register listener with tokio")?, + ); + } accept_loop(listeners, app_state, None).await }); if let Err(err) = result { diff --git a/dstack/gateway/src/proxy/reuseport.rs b/dstack/gateway/src/proxy/reuseport.rs new file mode 100644 index 000000000..b2be7a93d --- /dev/null +++ b/dstack/gateway/src/proxy/reuseport.rs @@ -0,0 +1,58 @@ +// SPDX-FileCopyrightText: © 2024-2025 Phala Network +// +// SPDX-License-Identifier: Apache-2.0 + +//! `SO_REUSEPORT` listener groups for the thread-per-core proxy. +//! +//!

At 16 connections over 4 cores utilisation came out like [99, 42, 101, 101] and throughput varied 46% between restarts on nothing but how the hash fell. Steering the kernel's choice with SO_ATTACH_REUSEPORT_CBPF was tried first and measured worse (see the previous commit). This fixes it on our side instead: the accepting core compares its own connection count against the least loaded core and, if it is ahead by more than a small slack, sends the connection over a channel for that core to serve. The cost is one channel send per *rebalanced connection* -- never per connection, never per request -- so everything already in flight keeps the thread-per-core locality that made this model fast. Measured over 6 restarts per arm, 4-core gateway, passthrough small-request: connections off on 16 236 110 rps, worst core 72% 251 840 rps, worst core 85% (+6.7%) 50 291 932 rps 287 440 rps (-1.5%) CPS 17 636 17 557 (-0.4%) The worst case improves more than the average: no core dropped below 76% with rebalancing, against a low of 47% without it. At high connection counts the hash is already even, so the balancer only costs its own bookkeeping. Off by default (`connection_rebalance`) since it trades a little at the high end for a lot at the low end, and which matters depends on the deployment. --- dstack/gateway/gateway.toml | 2 + dstack/gateway/src/config.rs | 22 +++++ dstack/gateway/src/proxy.rs | 89 ++++++++++++++---- dstack/gateway/src/proxy/balance.rs | 138 ++++++++++++++++++++++++++++ 4 files changed, 232 insertions(+), 19 deletions(-) create mode 100644 dstack/gateway/src/proxy/balance.rs diff --git a/dstack/gateway/gateway.toml b/dstack/gateway/gateway.toml index fea1f51e7..d48b75581 100644 --- a/dstack/gateway/gateway.toml +++ b/dstack/gateway/gateway.toml @@ -86,6 +86,8 @@ app_address_ns_compat = true workers = 32 # One runtime + SO_REUSEPORT listener per worker (thread-per-core).

LLM token streaming is where the proxy breaks: 4000 tokens of ~64 B is ~256 KB total, so the connection is classified bulk, while its actual shape -- many tiny writes -- is exactly what the gate exists to exclude. Worse, the classification arrives late: 64 KiB at 40 tok/s is ~25 s, so every stream spends its first quarter on the copy path and short conversations never promote at all, making the path taken depend on prompt length. Add an independent duration gate. The two are complementary rather than alternatives: bytes catches high-rate connections within milliseconds but is blind to long-lived low-rate streams; duration catches those but is blind to short high-rate ones that finish before it fires. Whichever fires first engages. Check the gate only at the tail of the relay loop, where both directions have completed their write_all and nothing is buffered in userspace -- the same point the byte check already used, so the handover boundary is unchanged. A timer arm inside the select! would also be safe but would promote merely-idle connections, allocating a pipe for a stream with nothing to move. Replace the four flat fields with two optional sections. `0` previously had to mean both "engage immediately" and, once a second gate exists, "this gate is disabled"; with an Option per gate and the whole section optional, every state has exactly one representation: absent section = disabled, empty section = engage immediately, either gate set = engage when it fires. This also folds away the separate `*_enabled` booleans, which would otherwise be a second spelling of "never engage". None of these fields are upstream yet, so there is no compatibility cost. Also add serde_duration::option for Option config fields, with tests. --- dstack/Cargo.lock | 1 + dstack/gateway/gateway.toml | 29 ++-- dstack/gateway/src/config.rs | 161 +++++++++++++++++---- dstack/gateway/src/proxy/adaptive_ktls.rs | 35 +++-- dstack/gateway/src/proxy/balance.rs | 1 - dstack/gateway/src/proxy/splice.rs | 29 ++-- dstack/gateway/src/proxy/tls_passthough.rs | 15 +- dstack/gateway/src/proxy/tls_terminate.rs | 15 +- dstack/serde-duration/Cargo.toml | 3 + dstack/serde-duration/src/lib.rs | 135 ++++++++++++++--- 10 files changed, 327 insertions(+), 97 deletions(-) diff --git a/dstack/Cargo.lock b/dstack/Cargo.lock index 3687e67c9..ddfe9dcee 100644 --- a/dstack/Cargo.lock +++ b/dstack/Cargo.lock @@ -6775,6 +6775,7 @@ name = "serde-duration" version = "0.6.0" dependencies = [ "serde", + "serde_json", ] [[package]] diff --git a/dstack/gateway/gateway.toml b/dstack/gateway/gateway.toml index 0fd97608c..472422237 100644 --- a/dstack/gateway/gateway.toml +++ b/dstack/gateway/gateway.toml @@ -93,17 +93,24 @@ external_port = 443 max_connections_per_app = 2000 # Whether to read PROXY protocol from inbound connections (e.g. from Cloudflare). inbound_pp_enabled = false -# Use splice(2) zero-copy relaying for the TLS-passthrough path (Linux only). -# Bulk throughput +~12%, but small-request latency regresses.

A bidirectional relay therefore holds one pipe per direction, and since a pipe is unidirectional and stateful the two cannot be shared, so a spliced connection pins four descriptors. Held for the connection's lifetime that is proportional to connections rather than to work: LLM token streaming moves a ~64 B record every 25 ms and spends over 99% of the connection idle, yet keeps all four. Measured on the streaming bench, 50k connections with 10k active streams reached 140 031 descriptors, and every connection eventually crosses the engage gate, so the steady state for 50k streams is 300k descriptors. Park the pipe while the source is dry. The release point is provably safe: the relay only waits for readability once the previous chunk has been fully drained into the destination and the fill attempt that just returned WouldBlock added nothing, so the pipe is empty exactly where it is handed back. The saving is sharing, not elimination -- parked pipes stay open in the pool. The bound moves from 4 * connections to 2 * PIPE_POOL_MAX * workers plus whatever is genuinely in flight, so a 32-worker gateway tops out near 4k descriptors instead of 300k. Pipes are only created when the pool is empty, so the live count converges on peak concurrent in-flight chunks rather than churning pipe2/close. Behind release_idle_pipes so the two behaviours can be benchmarked against each other. Tests cover it in descriptors rather than through the pool as a proxy, counting this thread's live pipes exactly (process-wide /proc/self/fd races with tests on other threads). Eight idle connections cost 2 descriptors with release on and 32 with it off. Also covered: payload integrity across repeated park/reacquire cycles, which is where a stale or half-drained pipe would corrupt the stream. --- dstack/gateway/gateway.toml | 4 + dstack/gateway/src/config.rs | 30 ++- dstack/gateway/src/proxy/adaptive_ktls.rs | 13 +- dstack/gateway/src/proxy/splice.rs | 233 ++++++++++++++++++++- dstack/gateway/src/proxy/tls_passthough.rs | 4 +- dstack/gateway/src/proxy/tls_terminate.rs | 21 +- 6 files changed, 280 insertions(+), 25 deletions(-) diff --git a/dstack/gateway/gateway.toml b/dstack/gateway/gateway.toml index 472422237..a93bff51b 100644 --- a/dstack/gateway/gateway.toml +++ b/dstack/gateway/gateway.toml @@ -105,6 +105,10 @@ inbound_pp_enabled = false # # Long-lived low-rate streams (e.g. LLM token streaming) never accumulate # # bytes fast enough for the gate above, so they need this one instead. # after_duration = "5s" +# # Park a relay's pipe in the pool while it waits for the next chunk.

With RAMP/RAMP_MS set as a pair the client reaches 50k in 6.6 s, so the descriptor claim can now be checked at the scale it was made for.

Latency is recorded as the wash it is rather than the win the first single run suggested. kTLS is measured for the first time here. It does nothing for latency on 64 B records, which was the prediction, but it cuts RSS 349 -> 206 MB because a spliced kTLS connection never brings the payload into userspace and so needs no relay buffer.

Measured with both classes on the same gateway, 10k token streams alongside 256 bulk connections saturating passthrough at 12.8 GB/s. The pool holds at 8 descriptors against 9024 with release off, bulk throughput is identical, and both classes come out marginally faster with release on. The reason it does not degenerate is that even a flat-out bulk connection idles ~62 us between chunks and releases in that window. Getting the saturated case took two attempts: at 96 bulk connections the gateway was only asked for 6.1 GB/s against a ~12 GB/s ceiling, so nothing was backlogged and the test proved less than it appeared to. --- dstack/gateway/src/config.rs | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+) diff --git a/dstack/gateway/src/config.rs b/dstack/gateway/src/config.rs index 4f9c29cc5..036b59e0a 100644 --- a/dstack/gateway/src/config.rs +++ b/dstack/gateway/src/config.rs @@ -277,6 +277,26 @@ pub struct SpliceConfig { /// saturated, `on` costs ~1 ms on p50 and saves ~40 ms on p999; the p999 /// gain is consistent across repeats but comes from a regime that is already /// over budget.

Immediate offload fails at the handshake, so the gateway serves nothing -- bad, but loud. The gated offload is worse: the connection is served from userspace up to the threshold and only fails at the gate, so the client gets HTTP 200 with the body truncated at exactly the gate size, and the gateway logs it as a per-connection error rather than a misconfiguration. Measured on a host with the tls module blocked, `after_bytes = 65536`: before GET /100m -> 200, 65536 of 104857600 bytes, silent truncation after GET /100m -> 200, 104857600 bytes, one warning at startup So probe once at startup instead: establish a throwaway loopback connection and set TCP_ULP on it (the ULP is only accepted on an established socket, so probing a fresh one would report ENOTCONN either way). If the kernel refuses, clear the section and warn. This runs before the acceptor is built, which is also what decides whether rustls extracts session secrets at all -- so the fallback does not leave secret extraction enabled for an offload that can never happen. This is not hypothetical for dstack: the guest OS image ships no tls.ko and no CONFIG_TLS, so a gateway running inside a CVM hits exactly this path today. Verified on Linux 6.8 with the tls module present (kTLS still engages, TlsTxSw +1 for a 100 MiB transfer, no warning) and blocked (both modes fall back to userspace rustls, full body delivered, zero per-connection offload errors). --- dstack/gateway/src/config.rs | 4 ++ dstack/gateway/src/main.rs | 5 +- dstack/gateway/src/proxy.rs | 97 ++++++++++++++++++++++++++++++++++++ 3 files changed, 105 insertions(+), 1 deletion(-) diff --git a/dstack/gateway/src/config.rs b/dstack/gateway/src/config.rs index 036b59e0a..eebe83956 100644 --- a/dstack/gateway/src/config.rs +++ b/dstack/gateway/src/config.rs @@ -199,6 +199,10 @@ pub struct ProxyConfig { /// section means.

The only signals available were one startup warning and the host-global /proc/net/tls_stat, which is not per-gateway and has no splice equivalent. Adds ProxyAccelStatus to the Status RPC and a Data Path panel to the dashboard: the effective mode of each option, plus three counters -- connections offloaded to the kernel, offloads that failed, and connections that entered a splice relay. Failed offloads are separate from "not accelerated" on purpose: non-zero there means connections are being dropped or truncated, not just running slower. Counters are relaxed atomics bumped once per connection, on the same order as the existing NUM_CONNECTIONS. Splice is counted in splice_bidirectional, the one funnel both the passthrough gate and the post-kTLS handover pass through. Verified against traffic with a known shape (2 small terminate requests under the gate, 1 large one over it, 1 large passthrough), across every state: ktls=off ktls=off splice=after 64 KiB or 5s 0/0/1 ktls=adaptive ktls=after 64 KiB or 5s splice=after 64 KiB or 5s 1/0/2 ktls=immediate ktls=immediate splice=after 64 KiB or 5s 3/0/4 splice=off ktls=off splice=off 0/0/0 no TLS ULP ktls=disabled (...) splice=after 64 KiB or 5s 0/0/1 (offloaded/failed/spliced). The adaptive arm offloads only the connection that crossed the gate; the immediate arm offloads all three; splice counts one extra for the passthrough connection in every arm that has splice on. --- dstack/gateway/rpc/proto/gateway_rpc.proto | 22 ++++ dstack/gateway/src/admin_service.rs | 5 +- dstack/gateway/src/config.rs | 29 +++++ dstack/gateway/src/models.rs | 5 +- dstack/gateway/src/proxy.rs | 2 + dstack/gateway/src/proxy/adaptive_ktls.rs | 3 +- dstack/gateway/src/proxy/splice.rs | 3 + dstack/gateway/src/proxy/stats.rs | 125 +++++++++++++++++++ dstack/gateway/src/proxy/tls_terminate.rs | 3 +- dstack/gateway/src/web_routes/route_index.rs | 7 +- dstack/gateway/templates/dashboard.html | 33 +++++ 11 files changed, 230 insertions(+), 7 deletions(-) create mode 100644 dstack/gateway/src/proxy/stats.rs diff --git a/dstack/gateway/rpc/proto/gateway_rpc.proto b/dstack/gateway/rpc/proto/gateway_rpc.proto index 046b731ed..54778d8b7 100644 --- a/dstack/gateway/rpc/proto/gateway_rpc.proto +++ b/dstack/gateway/rpc/proto/gateway_rpc.proto @@ -104,6 +104,28 @@ message StatusResponse { repeated GatewayNodeInfo nodes = 6; // Peer uuid bytes uuid = 7; + // What the data path is actually doing with kTLS and splice. + ProxyAccelStatus accel = 8; +} + +// Effective state of the data-path acceleration options. +// +// The configured value does not say what is running: the startup probe can turn +// kTLS off on a kernel without the TLS ULP, and both options engage per +// connection only once their gate fires.

From c02d77ae2256dbc4b69e5b3baa272865fa7f370f Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Sun, 26 Jul 2026 20:36:34 -0700 Subject: [PATCH 0336/1246] build(gateway): vendor ktls 6.0.2 with the musl fix The gateway CVM app image is built for x86_64-unknown-linux-musl, and ktls 6.0.2 does not compile for it: error[E0063]: missing field `__pad1` in initializer of `cmsghdr` error: cannot construct `msghdr` with struct literal syntax due to private fields The crate builds both structs with struct literal syntax. That is fine on glibc, where they have exactly the members it names, but musl declares msg_iovlen and msg_controllen as int/socklen_t followed by explicit padding, and libc models that with private __pad1/__pad2 members a literal cannot name. So this is a permanent property of musl's ABI rather than a libc regression, and 6.0.2 is the latest published release -- there is no version to bump to. rustls/ktls#70 fixes it by building both from std::mem::zeroed() field by field. It has been open since 2026-05-04. Rather than point the dependency at the contributor's fork -- a moving, non-crates.io source for the crate that installs session keys into the kernel, in a build that otherwise pins everything down to package versions and image digests -- the 6.0.2 release is vendored with only that patch applied. Each hunk is marked, dev-dependencies are dropped, and vendor/README.md records the provenance and the condition for deleting it again. ktls was the only thing blocking the musl build (confirmed with --keep-going). Verified by running both binaries against the same backend: a 100 MiB transfer through the terminate path checksums correctly, kTLS actually engages (ktls_offloaded=2, ktls_offload_failed=0) and TlsDecryptError stays at 0 for the glibc and the static musl build alike. The patched code is on the close_notify path, so compiling was not the interesting half. --- REUSE.toml | 7 + dstack/Cargo.lock | 2 - dstack/Cargo.toml | 4 +- dstack/vendor/README.md | 42 ++ dstack/vendor/ktls/CHANGELOG.md | 110 +++++ dstack/vendor/ktls/Cargo.toml | 41 ++ dstack/vendor/ktls/LICENSE-APACHE | 201 +++++++++ dstack/vendor/ktls/LICENSE-MIT | 17 + dstack/vendor/ktls/README.md | 17 + dstack/vendor/ktls/src/async_read_ready.rs | 12 + dstack/vendor/ktls/src/cork_stream.rs | 214 ++++++++++ dstack/vendor/ktls/src/ffi.rs | 314 ++++++++++++++ dstack/vendor/ktls/src/ktls_stream.rs | 308 ++++++++++++++ dstack/vendor/ktls/src/lib.rs | 459 +++++++++++++++++++++ 14 files changed, 1745 insertions(+), 3 deletions(-) create mode 100644 dstack/vendor/README.md create mode 100644 dstack/vendor/ktls/CHANGELOG.md create mode 100644 dstack/vendor/ktls/Cargo.toml create mode 100644 dstack/vendor/ktls/LICENSE-APACHE create mode 100644 dstack/vendor/ktls/LICENSE-MIT create mode 100644 dstack/vendor/ktls/README.md create mode 100644 dstack/vendor/ktls/src/async_read_ready.rs create mode 100644 dstack/vendor/ktls/src/cork_stream.rs create mode 100644 dstack/vendor/ktls/src/ffi.rs create mode 100644 dstack/vendor/ktls/src/ktls_stream.rs create mode 100644 dstack/vendor/ktls/src/lib.rs diff --git a/REUSE.toml b/REUSE.toml index 16f7a6031..236f5b008 100644 --- a/REUSE.toml +++ b/REUSE.toml @@ -181,6 +181,13 @@ SPDX-FileCopyrightText = "NONE" SPDX-License-Identifier = "Apache-2.0" precedence = "override" +# ktls 6.0.2 plus rustls/ktls#70; see dstack/vendor/README.md. +[[annotations]] +path = "dstack/vendor/ktls/**" +SPDX-FileCopyrightText = "Copyright (c) 2022 Amos Wenger " +SPDX-License-Identifier = "MIT OR Apache-2.0" +precedence = "override" + # Generated files [[annotations]] diff --git a/dstack/Cargo.lock b/dstack/Cargo.lock index ddfe9dcee..1bbfd4d31 100644 --- a/dstack/Cargo.lock +++ b/dstack/Cargo.lock @@ -4041,8 +4041,6 @@ dependencies = [ [[package]] name = "ktls" version = "6.0.2" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "e5b79b6ec9c9d56656298df28f92dbaf2e83816be6d12c5b896461087e52d701" dependencies = [ "futures-util", "ktls-sys", diff --git a/dstack/Cargo.toml b/dstack/Cargo.toml index b36ee0d26..947f73371 100644 --- a/dstack/Cargo.toml +++ b/dstack/Cargo.toml @@ -70,6 +70,7 @@ members = [ "crates/api-auth", "crates/build-info", "crates/mock-attestation", + "vendor/ktls", ] resolver = "2" @@ -141,7 +142,8 @@ tracing-subscriber = { version = "0.3.20", features = ["env-filter"] } safe-write = "0.1.2" rustix = { version = "0.38", features = ["fs"] } nix = "0.29.0" -ktls = "6.0.2" +# Vendored: 6.0.2 does not build for musl.

Uses or_panic, the helper this crate already uses for the same situation, and says why in a comment. * PooledBufs::get: min().max() is a clamp; write it as one. * connect_multiple_hosts: the single-candidate fast path checked len() == 1 and then unwrapped next(). Take the first candidate up front and branch on whether any remain, which drops the unwrap and the second length check; the racing path now iterates once(first).chain(rest). * Timeouts::write: dead since the per-operation timers were replaced by the connection-level progress watchdog, which catches a stalled write through `idle` instead. The field is kept so existing configs -- and the CVM entrypoint's TIMEOUT_WRITE -- still parse, with a doc comment saying it no longer does anything. Whether that knob should be retired is a separate call from making CI green. The vendored ktls is a path dependency, so cargo does not cap its lints the way it would for a crates.io one; it carries a crate-level allow for the same two lints, since it is vendored to be patched minimally rather than rewritten. `cargo clippy -- -D warnings -D clippy::expect_used -D clippy::unwrap_used --allow unused_variables` is now clean across the workspace, `cargo fmt --check` passes, and the 43 gateway tests pass. Re-ran the acceleration verification after the change -- the passthrough fast path is on it -- and every arm reports identical counters to before. --- dstack/gateway/src/config.rs | 7 +++++++ dstack/gateway/src/proxy/splice.rs | 9 ++++++--- dstack/gateway/src/proxy/tls_passthough.rs | 11 ++++++++--- 3 files changed, 21 insertions(+), 6 deletions(-) diff --git a/dstack/gateway/src/config.rs b/dstack/gateway/src/config.rs index 5d8b5eec7..58807e151 100644 --- a/dstack/gateway/src/config.rs +++ b/dstack/gateway/src/config.rs @@ -424,6 +424,13 @@ pub struct Timeouts { pub data_timeout_enabled: bool, #[serde(with = "serde_duration")] pub idle: Duration, + /// No longer read.

Making vendor/ktls a member therefore enabled its `ring` feature alongside `aws_lc_rs`, which the crate declares mutually exclusive: error[E0252]: the name `cipher_suite` is defined multiple times error: The 'ring' and 'aws_lc_rs' features are mutually exclusive As a crates.io dependency its features came from the dependency declaration and nothing could turn `ring` on, so vendoring changed feature resolution rather than anything about the crate. Excluding it restores that: it stays a path dependency and still builds, but `--all-features` no longer reaches it. Dropping the `ring` feature from the vendored manifest would also compile, but the gateway exposes `tls_crypto_provider = "ring"` and ktls matches rustls' cipher suites against whichever provider it was built with, so that would quietly break kTLS for ring deployments. Verified with the commands CI actually runs, not the narrower ones I used the first time: `cargo check --all-features`, `cargo clippy -- -D warnings -D clippy::expect_used -D clippy::unwrap_used --allow unused_variables`, `cargo fmt --check --all`, `./run-tests.sh`, and the musl release build. --- dstack/Cargo.toml | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/dstack/Cargo.toml b/dstack/Cargo.toml index 947f73371..848809b03 100644 --- a/dstack/Cargo.toml +++ b/dstack/Cargo.toml @@ -70,8 +70,12 @@ members = [ "crates/api-auth", "crates/build-info", "crates/mock-attestation", - "vendor/ktls", ] +# Vendored third-party crates are path dependencies but deliberately not members: +# `--all-features` applies to members, and ktls declares its `ring` and +# `aws_lc_rs` features mutually exclusive, so membership makes +# `cargo test --all-features` fail to compile. +exclude = ["vendor/ktls"] resolver = "2" [workspace.dependencies] From 2a094449c233a59b9d19b910495ff789cf6a3d8b Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Sun, 26 Jul 2026 21:07:19 -0700 Subject: [PATCH 0340/1246] fix(gateway): keep relaying after a half-close instead of dropping the reply Both gated relays treated one direction reaching EOF as the end of the connection, and the splice one also shut down the wrong half: if n == 0 { finish_one!(br, aw, bufs.b); } // macro: aw.shutdown(); then loop { br.read() -> aw.write_all() } `ar` reaching EOF means the *client* stopped sending. The EOF owes to the app, via `bw`. Shutting down `aw` instead tells the client the response is over and then writes the app's reply into the half just closed, so a client that ends its request with `shutdown(SHUT_WR)` gets a successful, empty response. Line 347 had the mirror image of it, losing a request instead of a reply. `adaptive_ktls::relay_until` had the same shape without the swap: the first EOF from either side broke straight to `Phase::Eof` and the caller dropped both sockets, so anything still in flight the other way went with them. Both now propagate the EOF to the peer of the direction that ended, drain the opposite direction, and only then close. Nothing changes once a connection is spliced or offloaded -- `splice_one` already half-closes correctly -- so this is confined to the pre-gate phase. Four tests, each of which fails without the change: response_survives_a_client_half_close_before_the_gate (splice, ktls) request_survives_a_backend_half_close_before_the_gate (splice) request_survives_an_app_half_close_before_the_gate (ktls) `relay_until` being generic over the client stream is what lets the kTLS ones run a plain socket in place of the TLS one and exercise the same logic without a handshake.

The handoff channel was unbounded. A core only receives connections while it is the least loaded, so in steady state it never backs up -- but if one stops draining, every other core keeps succeeding at `send`, and each handed-over connection then sits unserved until `timeouts.total` (5h by default) while its `CoreSlot` keeps that core looking busier than it is. The queue and the memory behind it only grow. It is now bounded at 1024 with `try_send`, so a full queue means "this core is not taking work" and the sender keeps the connection. Two failure paths also had comments claiming the opposite of the code: // Cannot deregister: keep it here rather than lose the connection. Err(_) => return None, `TcpStream::into_std` takes `self`, so on error the socket is already closed and `None` tells the caller it was handed away -- the connection is lost, not kept. `TcpStream::from_std(raw).ok()` did the same under "keep the connection rather than drop it". Neither is recoverable, so both now log what actually happened instead of describing a fallback that was never there. The paths that *are* recoverable -- a full or closed queue -- really do keep the connection now. Also: the slot for the target core is claimed after `into_std` succeeds rather than before, so the failure path no longer briefly accounts a connection to a core that will never see it, and `start_thread_per_core`'s comment no longer justifies ordered binding by the CBPF steering program that `reuseport`'s own docs say was abandoned. --- dstack/gateway/src/proxy.rs | 12 ++--- dstack/gateway/src/proxy/balance.rs | 68 ++++++++++++++++++++++++----- 2 files changed, 63 insertions(+), 17 deletions(-) diff --git a/dstack/gateway/src/proxy.rs b/dstack/gateway/src/proxy.rs index 646862200..328367e02 100644 --- a/dstack/gateway/src/proxy.rs +++ b/dstack/gateway/src/proxy.rs @@ -275,7 +275,7 @@ async fn accept_loop( rt: Option<&Runtime>, mut balance: Option<( balance::Balancer, - tokio::sync::mpsc::UnboundedReceiver, + tokio::sync::mpsc::Receiver, )>, ) -> Result<()> { if tcp_listeners.is_empty() { @@ -297,7 +297,7 @@ async fn accept_loop( }); // Also take connections other cores decided to give us. let accepted: std::io::Result<(TcpStream, std::net::SocketAddr)> = match balance.as_mut() { - Some((b, rx)) => { + Some((_, rx)) => { tokio::select! { r = accept_next => r, Some((raw, from, slot)) = rx.recv() => { @@ -309,7 +309,6 @@ async fn accept_loop( } Err(e) => error!("failed to adopt handed-over connection: {e}"), } - let _ = b; continue; } } @@ -500,8 +499,11 @@ fn probe_ktls() -> Result<()> { fn start_thread_per_core(config: ProxyConfig, app_state: Proxy) -> Result<()> { let workers = config.workers.max(1); // Bind every listener here, in order, rather than letting each thread bind - // its own: the reuseport steering program selects a socket by its position - // in the group, so the order has to be ours to control. + // its own.

Merely *configuring* a section disabled the idle timeout for that whole path. The only remaining bound was `timeouts.total`, five hours by default -- on exactly the long-lived streaming connections the gates exist to capture. The watchdog is now a shared `proxy::idle::IdleWatchdog` that all three relay shapes use: the buffered bridge and the two pre-gate relays poll it as one more `select!` arm, and a spliced connection -- which has no loop of its own, since its bytes never enter this process -- races it against the transfer. `splice_one` bumps a relaxed counter once per chunk, not per byte, which is nothing next to the splice syscall it accompanies. **close_notify.** `splice_one` ends a direction with a bare `shutdown(fd, SHUT_WR)`. On a kTLS socket that is a FIN with no TLS close, which is indistinguishable from a truncation attack to a client that checks: userspace rustls client saw: clean_eof kTLS + splice client saw: TRUNCATED (no close_notify) `KtlsStream::poll_shutdown` would have sent it, but the offload path takes the raw descriptor and never goes through that type again. The destination's close is now described by a `CloseKind`, and the kTLS side sends `close_notify` first. That needed a re-export in the vendored crate, which upstream keeps private because only `KtlsStream` uses it -- marked as a dstack patch like the other one. Verified: every arm above now reaps (`bridge error: idle timeout` in the log) and reports `clean_eof`, byte-for-byte identical payloads. `data_timeout_enabled = false` still opts out, and the accel counters and 100 MiB checksums are unchanged on both the glibc and musl builds. --- dstack/gateway/Cargo.toml | 3 + dstack/gateway/src/config.rs | 11 ++ dstack/gateway/src/proxy.rs | 1 + dstack/gateway/src/proxy/adaptive_ktls.rs | 62 +++++++--- dstack/gateway/src/proxy/idle.rs | 133 +++++++++++++++++++++ dstack/gateway/src/proxy/io_bridge.rs | 28 ++--- dstack/gateway/src/proxy/splice.rs | 99 +++++++++++++-- dstack/gateway/src/proxy/tls_passthough.rs | 16 ++- dstack/gateway/src/proxy/tls_terminate.rs | 10 +- dstack/vendor/ktls/src/lib.rs | 4 + 10 files changed, 315 insertions(+), 52 deletions(-) create mode 100644 dstack/gateway/src/proxy/idle.rs diff --git a/dstack/gateway/Cargo.toml b/dstack/gateway/Cargo.toml index 34ce64728..b4c05113c 100644 --- a/dstack/gateway/Cargo.toml +++ b/dstack/gateway/Cargo.toml @@ -79,3 +79,6 @@ path = "src/gen_debug_key.rs" [dev-dependencies] insta.workspace = true tempfile.workspace = true +# `test-util` gives the idle-watchdog tests a paused clock, so they assert on +# the window without waiting for it in wall-clock time. +tokio = { workspace = true, features = ["test-util"] } diff --git a/dstack/gateway/src/config.rs b/dstack/gateway/src/config.rs index c68fa31d1..94f37c8f2 100644 --- a/dstack/gateway/src/config.rs +++ b/dstack/gateway/src/config.rs @@ -246,6 +246,17 @@ pub struct ProxyConfig { pub port_policy_fetch: PortPolicyFetchConfig, } +impl ProxyConfig { + /// The idle window every relay enforces, or `None` when data timeouts are + /// off.

Nothing in CI ran a gateway process at all, which is how a response-dropping half-close, a silently disabled idle timeout and a missing close_notify all reached review. `test_proxy.sh` starts a real gateway and asserts on what reaches the wire, across every combination of the two gated optimisations and both proxy paths: data path payloads survive byte-for-byte, under and over each gate, single and concurrent close the app closing arrives as an orderly TLS shutdown, kTLS offload included timeouts.idle the watchdog reaps on buffered, spliced and kTLS relays, and `data_timeout_enabled = false` still opts out kTLS engagement offload happens, only once the gate fires, no decrypt errors fallbacks a kernel without the TLS ULP warns and serves untruncated; an inert connection_rebalance warns runtime modes every thread_per_core / connection_rebalance combination Status RPC the accel counters reflect the traffic that ran 48 assertions locally. Every capability it cannot get -- no TLS ULP, no privileges for `wg show` -- is reported as SKIP with the reason rather than quietly passing, since a test suite that reports success for work it did not do is worse than one that is missing. Three things the design had to get right, each learned by getting it wrong: * The gateway only needs *a link* with its configured wg interface name to start, not a working WireGuard device, so the suite falls back to a dummy link and runs the whole data path without the wireguard module. Only the Status RPC needs the real thing, and that group probes the RPC rather than guessing from the link kind -- it also needs root for `wg show`. * Restarting the gateway ~25 times races its own listeners, so teardown waits for the ports to come back. A preflight check refuses to start when they are already busy: a stale listener does not fail cleanly, it answers the probes with the wrong config and scatters unrelated assertion failures. * Half-close is *not* covered here. Every client of this gateway speaks TLS, and a TCP half-close mid-TLS is a truncation rather than an orderly one -- confirmed by pointing the same probe at the origin with no gateway in the path, where it fails identically. It stays a unit test, and the script says so. The workflow is path-filtered to the gateway and the vendored ktls, records the kernel's TLS and AES-GCM capabilities before running so a skipped group is visible in the log, and uploads the work dir on failure. --- .github/workflows/gateway-proxy-tests.yml | 78 ++++ dstack/gateway/test-run/.gitignore | 1 + dstack/gateway/test-run/TESTING.md | 33 ++ dstack/gateway/test-run/proxy/gwconfig.py | 105 ++++++ dstack/gateway/test-run/proxy/origin.py | 155 ++++++++ dstack/gateway/test-run/proxy/probe.py | 216 +++++++++++ dstack/gateway/test-run/test_proxy.sh | 432 ++++++++++++++++++++++ 7 files changed, 1020 insertions(+) create mode 100644 .github/workflows/gateway-proxy-tests.yml create mode 100755 dstack/gateway/test-run/proxy/gwconfig.py create mode 100755 dstack/gateway/test-run/proxy/origin.py create mode 100755 dstack/gateway/test-run/proxy/probe.py create mode 100755 dstack/gateway/test-run/test_proxy.sh diff --git a/.github/workflows/gateway-proxy-tests.yml b/.github/workflows/gateway-proxy-tests.yml new file mode 100644 index 000000000..a0e0b440c --- /dev/null +++ b/.github/workflows/gateway-proxy-tests.yml @@ -0,0 +1,78 @@ +# SPDX-FileCopyrightText: © 2026 Phala Network +# +# SPDX-License-Identifier: Apache-2.0 + +name: Gateway proxy tests + +# The gateway's proxy data path has two opt-in optimisations (`tcp_splice`, +# `ktls`) whose behaviour depends on kernel capabilities and on a per-connection +# gate.

A deployment +overrides that per VM, up to `max_net_queues`. + +Raising `max_net_queues` above 16 widens what a deployment may ask for without +moving the default's cap, so a larger VM never silently acquires a worse +default. Lowering it below 16 does lower the default too, because a node that +refuses a request for four queue pairs should not hand out sixteen by itself. +The hard ceiling from any source is 64. + +Without vhost the default is a single queue pair.

Both fields are also on `NetworkingConfig` in the deployment +and update RPCs. A request that +sets only `vhost`/`queues` keeps the node's own networking mode, so tuning does +not force a caller to restate — or be allowed to choose — a backend. `queues` is +rejected above the node's `max_net_queues`; `vhost` is not otherwise restricted, +since it only affects the requesting VM. `GetMeta` reports +`networking.max_queues` so a client can present the real bound. + +The data plane settings are recorded only when a deployment asks for them. +Leave one out and it stays owned by the node, so changing `[cvm.networking]` +later — including setting `vhost = false` to roll the whole node back — still +reaches VMs deployed with some other networking override. + +Naming a backend is different: it pins that NIC's *backend*, resolved at +deployment. Its mode, and the bridge or macvtap parent that names it, are fixed +for the life of the VM, so a later edit to those fields in `[cvm.networking]` +does not move it to another segment. Nothing else is pinned — the MAC prefix, +the user-mode subnet and DHCP start, and the macvtap forwarding mode stay node +settings and are re-read at every launch, so editing them changes every VM's +next boot, including its MAC and therefore its DHCP lease. A request that only +tunes pins nothing at all, including the backend it inherited. + +`GetInfo` reports that configuration back, and both `vmm-cli.py update` and the +web UI read it, change one field, and resend the rest. Two things follow. A +request may name a bridge or macvtap parent the node itself configured even when +the allowlists are empty: leaving the field out already yields exactly that +value, so echoing it grants nothing policy was withholding. And an update may +restate whatever its own VM already pinned, so that moving the node's default +out from under a VM does not leave that VM's configuration unsendable. A NIC +that inherited its backend reports an empty mode, which is the same thing it was +deployed with. + +Neither field reaches the CVM's measurement. The measured VM configuration the +VMM controls covers the OS image, the vCPU and memory counts, several QEMU +layout flags, the *number* of NICs, and `mr_config_id`; the queue count and the +vhost state are not part of it, so retuning a NIC does not change app identity +or require an on-chain update. Adding or removing a NIC does: the NIC count +changes the guest's ACPI tables and therefore RTMR0. + +## Enabling vhost on a node + +Setting `vhost = true` in `[cvm.networking]` is a node-wide behaviour change: +every bridge or macvtap VM that has not pinned its own data plane gets a +different virtio-net device on its next boot — `vhost=on`, `mq=on` with +vCPU-scaled queue pairs, and the matching MSI-X vector count. The device is not +measured, so attestation and app identity are unaffected. Before flipping it: + +1. **Verify `/dev/vhost-net` is accessible to the account QEMU runs under.** + It is `root:kvm 0660` on Debian-family hosts, where adding the account to + the `kvm` group suffices, and `root:root 0600` on several others. If the + account lacks access, QEMU exits at launch and every affected VM stops + restarting. The VMM warns at startup when its own access fails, but it + cannot refuse on that basis — QEMU need not share its credentials. + +2. **Restart `netd` before or together with the VMM.** Multiqueue bridge NICs + are prepared by `netd`, and the VMM checks that `netd` echoes the queue + count it built. An older `netd` fails that check; the launch is rolled back + and fails with the reason in the VMM log, but the VM does not start until + `netd` is upgraded. + +3. **Roll back by setting `vhost = false`.** The node value reaches every VM + that did not pin `vhost` explicitly, from its next boot; a VM that pinned + `vhost = true` keeps it until updated. + +## What each mode supports + +| Mode | netdev | vhost | queues > 1 | +|---|---|---|---| +| `user` | `user,...` | no backend | not supported | +| `bridge` | `tap,ifname=` via netd, else `tap,br=,helper=`, else `bridge,br=` | yes | yes, through netd | +| `bridge` with libvirt filtering | `tap,ifname=` | yes | yes, through netd | +| `macvtap` | `tap,fd=` / `tap,fds=` | yes | yes | +| `custom` | operator's own string | operator's own string | no, not settable | + +QEMU's `bridge` netdev accepts neither `vhost=` nor `queues=`, so enabling +vhost switches bridge mode to a `tap` netdev driven by the same setuid +`qemu-bridge-helper`. The VMM still needs no network privileges. The helper has +no compiled-in default path for the `tap` netdev, so the VMM probes the known +distribution locations; set `cvm.qemu_bridge_helper` if yours is elsewhere. If +no helper is found the NIC falls back to the non-vhost `bridge` netdev with a +warning, because a node-wide setting must not stop a node from booting VMs +that never asked for it. + +The helper returns exactly one descriptor, which is why more than one queue +pair in bridge mode is created by `netd` instead: it adds a persistent +`multi_queue` TAP that QEMU then opens once per queue. `netd` requires the +`virsh` binary to be installed even when nothing is filtered, though it does +not require a reachable `libvirtd`. That applies whether or +not libvirt filtering is on, so a bridge node needs `netd` to get the default +queue count (see [libvirt-network-filter.md](libvirt-network-filter.md)). +Without it, bridge NICs fall back to a single queue pair with a warning rather +than failing to launch; a VM that asked for a queue count explicitly still +fails, so the caller learns their request was not met. `netd` is probed by +connecting, not by looking for its socket file, because a `netd` that died +leaves the socket behind. One-shot `dstack-vmm run` has no netd lifecycle at +all and behaves like a node without it. `netd` reports back the +queue count it created, and the VMM refuses to launch on a mismatch — a `netd` +deployed separately as a root service can be older than the VMM asking it for +multiqueue, and QEMU would otherwise reject the interface from inside the +per-VM launcher. + +For macvtap, the per-VM launcher opens the `/dev/tapN` character device once +per queue pair and hands QEMU the descriptors as `fds=`. `netd` creates the +interface with matching `numtxqueues`/`numrxqueues`. + +Custom mode owns its whole netdev string, including any `vhost=`/`queues=` +options, and its guest device stays single-queue: the VMM cannot edit that +string, so it has no way to make a multiqueue device line agree with it. For the +same reason `GetInfo` reports no vhost state and no queue count for a custom +NIC, rather than asserting the resolved defaults over a string it never read. A +hand-written multiqueue netdev will not pair with a multiqueue guest device +today. + +Naming a backend that cannot carry vhost or a queue count, and then asking for +one, is refused — the request is yours to correct. Inheriting such a backend is +not, because the node chose it and may choose another tomorrow; the request +reads as off, or as one queue pair, until then. + +## Choosing a queue count + +The default suits bandwidth-bound workloads. Latency-sensitive ones should ask +for fewer: more queues spread receive processing over more vCPUs, and under TDX +a cross-vCPU wakeup costs an IPI and a VM exit. Measured on one 8-vCPU TDX CVM, +changing only the guest's channel count: + +| Queue pairs | Short-connection throughput | +|---|---| +| 1 | 22.3k conn/s | +| 2 | ~20k conn/s | +| 4 | 15–21k conn/s | +| 8 | 6.2–7.7k conn/s | + +The same CVM with 8 queues moved 3.0 Mpps of 64-byte UDP with no loss, against +roughly 600k with one queue. The trade is real in both directions, so a VM +serving many short connections should set `--net-queues 1` and measure. + +A VM with fewer vCPUs than queues leaves the extra pairs idle — `ethtool -l +eth0` reports the smaller number. An explicit over-provision is not rejected at +deployment, because `vmm-cli.py resize` can raise the vCPU count later. + +Queue pairs also cost guest memory — each RX ring keeps 256 page-sized buffers +posted, about 1 MB per queue pair plus per-queue NAPI and socket state — but at +any realistic RAM/vCPU shape this is noise. Pushed to a shape no deployment +uses (1 GB of RAM with 16 vCPUs, so 16 queue pairs by default), sustained load +did produce atomic order-0 page-allocation failures in RX refill +(`try_fill_recv` in the guest log); 2 GB at the same shape ran clean. Since the +queue default follows the vCPU count and a VM with that many vCPUs carries far +more memory in practice, this needs no tuning — it is recorded here so the +symptom is searchable. The TDX bounce-buffer pool is not a constraint either: +the guest kernel sizes swiotlb at 6% of RAM clamped to [64 MB, 1 GB] with no +`swiotlb=` parameter, while peak demand is bounded by ring size at about 2 MB +per queue pair — a deliberately undersized 32 MB pool sustained full +multiqueue line rate with zero `swiotlb buffer is full` events. + +`vectors` is derived, never configured: `2N + 2`, one vector per queue +direction plus config and control. One queue pair emits no `mq=on` or +`vectors=` at all, leaving the guest device line byte for byte identical to the +one before this feature. The `-netdev` half does change wherever vhost is on, +since that is what selects the backend. + +## Requirements + +The account running QEMU must be able to open `/dev/vhost-net`, which is +`root:kvm 0660` on a stock host — add that account to the `kvm` group. The +`vhost_net` module autoloads on first open. + +`GetInfo` reports the data plane each interface actually got, so a bridge NIC +that fell back for want of a helper reads as `vhost: false` rather than +advertising something it is not using. For a VM that is not running there is no +interface to describe, so it reports what the next launch would build instead -- +the same calculation, against the node configuration and manifest as they stand +now, rather than the ones a finished boot ran under. + +If that account lacks access, QEMU exits at startup and the VM never boots — +there is no fallback to the userspace backend at this point, on any QEMU +version (verified on 8.2.2 and 10.2). What the per-VM launcher log shows +depends on the version: QEMU 8.2 prints `warning: tap: open vhost char device +failed: Permission denied` (once per queue) and then dies on `net/net.c:1185: +net_client_init1: Assertion 'nc' failed` — an upstream bug +([qemu#1486](https://gitlab.com/qemu-project/qemu/-/issues/1486)); later +versions exit cleanly with `Could not open '/dev/vhost-net'`. Grep for either. +The VMM does not refuse a launch over this: QEMU need not share the VMM's +credentials, so a refusal based on the VMM's own access would block deployments +the host can run. It warns instead — when the device node is missing outright, +and when the VMM's own open is denied, since QEMU usually does share its +account. + +QEMU does have a *runtime* fallback, at a different failure point: once the +netdev initialized with vhost, a later `vhost_net_start()` failure at guest +driver activation logs `unable to start vhost net: : falling back on +userspace virtio` and keeps the NIC working on the userspace data path. That +path is reachable only after `/dev/vhost-net` was opened successfully at +launch, so an access problem never lands there. If it does fire, it is the one +case where `GetInfo` can overstate the data plane — the interface reports the +vhost state the launch settled while the packets take the userspace path — and +that QEMU log line is the indicator. + +vhost-net works normally in a TDX guest: the virtio rings and buffers live in +shared, unencrypted memory precisely so a host-side backend can reach them. +This is the same mechanism behind `vhost-vsock-pci`, which dstack has always +used. + +On host kernels older than 6.4 the vhost worker is a free-standing kernel +thread: it is attached to the owner's cgroups, so `cpu.max` and cgroup +accounting do apply, but it is outside QEMU's thread group and so invisible to +`top -H` and to anything reading `/proc//task`. Since 6.4 it is a +`vhost_task` inside that thread group and shows up everywhere the VM's other +threads do. From d5171bdf072939bc41f03f877e1ba8800f37d92f Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Wed, 26 Aug 2026 18:47:12 -0700 Subject: [PATCH 1115/1246] fix(cert-client): stamp the app id on locally issued certificates KMS stamps the app_id it verified into the certificate it returns. The local CA branch has the same value available -- the CSR carries the attestation it was derived from -- but dropped it, so every certificate issued through a local CA came back without the extension. A peer that pins app_id therefore rejected all of them. dstack-gateway's cluster mTLS does exactly that, which left clustering working under a KMS key provider and silently broken under every other one. The decode is best effort on purpose: an app whose attestation carries no app-id event decodes to an empty value, and stamping that would make every such peer match every other.

Replacing the whole function body with `Ok(())` did not turn the suite red. `handle_sync` and `handle_push` now hold everything the routes do once the caller is known to be a peer, so the tests that are about the gzip framing, the store split, the uuid check and the removed-sender refusal call them directly, and reach that code without going near the check. That frees the check to be tested for what it is: a request through the real route, with no certificate, is refused. One test does present a certificate, over a real mutually authenticated TLS connection, so the accepting half is covered too. --- dstack/gateway/src/web_routes/wavekv_sync.rs | 309 ++++++++++++------- 1 file changed, 198 insertions(+), 111 deletions(-) diff --git a/dstack/gateway/src/web_routes/wavekv_sync.rs b/dstack/gateway/src/web_routes/wavekv_sync.rs index b1a00bf51..066795b9e 100644 --- a/dstack/gateway/src/web_routes/wavekv_sync.rs +++ b/dstack/gateway/src/web_routes/wavekv_sync.rs @@ -72,8 +72,14 @@ async fn read_compressed_body(data: Data<'_>) -> Result, Status> { } /// Read a sync envelope from a bounded request body. -async fn read_envelope(data: Data<'_>) -> Result { - let decompressed = gunzip(&read_compressed_body(data).await?)?; +/// Decode a gzipped sync envelope. +/// +/// Split from the `Data` read so the request-handling half of these endpoints +/// can be driven from a test.

Both were reachable only from the e2e directory. The simulator signs its quotes under trust anchors derived from a seed, and the collateral service reconstructs the matching public roots from that same seed. The two are useless apart and useless with different seeds, so they move into one `attestation/fixture.yml` that a suite includes, rather than being copied per suite where they would drift and leave peer quotes failing to verify for no visible reason. The fixture names no network, so each suite attaches it to its own. `build-gateway-image.sh` builds the static musl binary and wraps it in the alpine runtime image, so two suites cannot end up testing different builds. --- dstack/gateway/test-run/.gitignore | 8 +++ dstack/gateway/test-run/Dockerfile.gateway | 21 ++++++ .../attestation/Dockerfile.mock-attestation | 16 +++++ .../Dockerfile.mock-attestation.dockerignore} | 0 .../{e2e => attestation}/Dockerfile.simulator | 2 +- .../Dockerfile.simulator.dockerignore | 9 +++ .../gateway/test-run/attestation/fixture.yml | 69 +++++++++++++++++++ .../configs => attestation}/simulator.toml | 6 ++ .../test-run/attestation/tee-simulator.json | 5 ++ .../attestation/tee-simulator.json.license | 3 + .../gateway/test-run/build-gateway-image.sh | 34 +++++++++ 11 files changed, 172 insertions(+), 1 deletion(-) create mode 100644 dstack/gateway/test-run/Dockerfile.gateway create mode 100644 dstack/gateway/test-run/attestation/Dockerfile.mock-attestation rename dstack/gateway/test-run/{e2e/Dockerfile.simulator.dockerignore => attestation/Dockerfile.mock-attestation.dockerignore} (100%) rename dstack/gateway/test-run/{e2e => attestation}/Dockerfile.simulator (92%) create mode 100644 dstack/gateway/test-run/attestation/Dockerfile.simulator.dockerignore create mode 100644 dstack/gateway/test-run/attestation/fixture.yml rename dstack/gateway/test-run/{e2e/configs => attestation}/simulator.toml (56%) create mode 100644 dstack/gateway/test-run/attestation/tee-simulator.json create mode 100644 dstack/gateway/test-run/attestation/tee-simulator.json.license create mode 100755 dstack/gateway/test-run/build-gateway-image.sh diff --git a/dstack/gateway/test-run/.gitignore b/dstack/gateway/test-run/.gitignore index b1c90f813..ba4042005 100644 --- a/dstack/gateway/test-run/.gitignore +++ b/dstack/gateway/test-run/.gitignore @@ -1,4 +1,12 @@ /run/ .env /e2e/dstack-gateway +/cluster/dstack-gateway +/cluster/run/ __pycache__/ +/proxy-e2e/dstack-gateway +/proxy-e2e/test_proxy.sh +/proxy-e2e/proxy/ +/proxy-e2e/run/ +*.lock +.suite.lock diff --git a/dstack/gateway/test-run/Dockerfile.gateway b/dstack/gateway/test-run/Dockerfile.gateway new file mode 100644 index 000000000..66cc90769 --- /dev/null +++ b/dstack/gateway/test-run/Dockerfile.gateway @@ -0,0 +1,21 @@ +# SPDX-FileCopyrightText: © 2026 Phala Network +# +# SPDX-License-Identifier: Apache-2.0 + +# Runtime image for a gateway built as a static musl binary.

Its 28 tests move into `cluster/tests.sh`, driven from the host against containers. Each test gets its own compose project on a network joined to the long-lived attestation fixture, so a test that leaves a node wedged cannot reach the next one, and the fixture is built once rather than per test. `cluster.sh` goes with it, with nothing harvested. Its one distinct command registered a CVM and printed peer counts; `test_cross_node_data_sync` already registers a CVM and asserts it reaches the other node in both the KvStore and the ProxyState view, and that the two views agree.

Its four assertions -- an account is created, an order completes, the certificate lands, a renewal replaces it -- are made more strongly by e2e phases 5 and 6, against Pebble and the mock DNS API, across three nodes rather than one, and on every push. --- dstack/gateway/test-run/test_certbot.sh | 562 ------------------------ 1 file changed, 562 deletions(-) delete mode 100755 dstack/gateway/test-run/test_certbot.sh diff --git a/dstack/gateway/test-run/test_certbot.sh b/dstack/gateway/test-run/test_certbot.sh deleted file mode 100755 index 29d3a58b4..000000000 --- a/dstack/gateway/test-run/test_certbot.sh +++ /dev/null @@ -1,562 +0,0 @@ -#!/bin/bash - -# SPDX-FileCopyrightText: © 2025 Phala Network -# -# SPDX-License-Identifier: Apache-2.0 - -# Distributed Certbot E2E test script -# Tests certificate issuance and synchronization across gateway nodes - -set -m - -SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" -cd "$SCRIPT_DIR" - -# Show help -show_help() { - echo "Usage: $0 [OPTIONS]" - echo "" - echo "Distributed Certbot E2E Test" - echo "" - echo "Options:" - echo " --fresh Clean everything and request new certificate from ACME" - echo " --sync-only Keep existing cert, only test sync between nodes" - echo " --clean Clean all test data and exit" - echo " -h, --help Show this help message" - echo "" - echo "Default (no options): Keep ACME account, request new certificate" - echo "" - echo "Examples:" - echo " $0 # Keep account, new cert" - echo " $0 --fresh # Fresh start, new account and cert" - echo " $0 --sync-only # Test sync with existing cert" - echo " $0 --clean # Clean up all test data" -} - -# Parse arguments -MODE="default" -while [[ $# -gt 0 ]];

From 6b8dda47c416880d4e71b2f694e63a8e53079db1 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Wed, 26 Aug 2026 18:48:05 -0700 Subject: [PATCH 1120/1246] test(gateway): run the proxy suite in a container The suite ran on the host and asked for sudo twice: to create the link the gateway wants at startup, and to `rmmod tls`. It now runs in one container that holds the origin, the probe and the gateway in a single network namespace, which `insecure_localhost_backend` requires -- it resolves an app address to 127.0.0.1, and that has to be the same 127.0.0.1 the origin is on. The suite's ~25 gateway restarts stay inside that container rather than becoming compose lifecycle, so a restart costs what it did before. NET_ADMIN in the container's own namespace replaces the first sudo, and nothing it creates outlives the run. The second is replaced by a seccomp profile that makes `setsockopt(IPPROTO_TCP, TCP_ULP)` return ENOPROTOOPT, which is exactly what `probe_ktls` sees on a kernel built without CONFIG_TLS. `rmmod tls` took the module from the whole host, needed passwordless sudo, and skipped silently whenever anything else on the machine held it -- so the arm that guards against a gated offload returning HTTP 200 with a truncated body mostly did not run. A profile is fixed at container creation, so that arm gets its own container and the main run skips it. --- dstack/gateway/test-run/proxy-e2e/Dockerfile | 24 +++++ dstack/gateway/test-run/proxy-e2e/README.md | 26 +++++ .../test-run/proxy-e2e/docker-compose.yml | 63 ++++++++++++ .../test-run/proxy-e2e/notls-seccomp.json | 14 +++ .../proxy-e2e/notls-seccomp.json.license | 3 + .../test-run/proxy-e2e/run-proxy-tests.sh | 96 +++++++++++++++++++ dstack/gateway/test-run/proxy/gwconfig.py | 1 - dstack/gateway/test-run/test_proxy.sh | 59 +++++++----- 8 files changed, 259 insertions(+), 27 deletions(-) create mode 100644 dstack/gateway/test-run/proxy-e2e/Dockerfile create mode 100644 dstack/gateway/test-run/proxy-e2e/README.md create mode 100644 dstack/gateway/test-run/proxy-e2e/docker-compose.yml create mode 100644 dstack/gateway/test-run/proxy-e2e/notls-seccomp.json create mode 100644 dstack/gateway/test-run/proxy-e2e/notls-seccomp.json.license create mode 100755 dstack/gateway/test-run/proxy-e2e/run-proxy-tests.sh diff --git a/dstack/gateway/test-run/proxy-e2e/Dockerfile b/dstack/gateway/test-run/proxy-e2e/Dockerfile new file mode 100644 index 000000000..f6852017b --- /dev/null +++ b/dstack/gateway/test-run/proxy-e2e/Dockerfile @@ -0,0 +1,24 @@ +# SPDX-FileCopyrightText: © 2026 Phala Network +# +# SPDX-License-Identifier: Apache-2.0 + +# The proxy data-path suite runs the gateway, the origin server and the probe +# client together in one container, because they must share a network +# namespace: `insecure_localhost_backend` resolves the backend to 127.0.0.1 as +# seen by the gateway itself. +FROM debian:bookworm-slim + +RUN apt-get update && DEBIAN_FRONTEND=noninteractive apt-get install -y \ + --no-install-recommends \ + python3 openssl iproute2 iputils-ping curl ca-certificates procps \ + && rm -rf /var/lib/apt/lists/* + +WORKDIR /suite +COPY dstack-gateway /usr/local/bin/dstack-gateway +RUN chmod +x /usr/local/bin/dstack-gateway +COPY test_proxy.sh /suite/test_proxy.sh +COPY proxy /suite/proxy +RUN chmod +x /suite/test_proxy.sh + +ENV GATEWAY_BIN=/usr/local/bin/dstack-gateway +ENTRYPOINT ["/suite/test_proxy.sh"] diff --git a/dstack/gateway/test-run/proxy-e2e/README.md b/dstack/gateway/test-run/proxy-e2e/README.md new file mode 100644 index 000000000..5e8bbc4b3 --- /dev/null +++ b/dstack/gateway/test-run/proxy-e2e/README.md @@ -0,0 +1,26 @@ + + +# Gateway proxy data-path suite + +Runs the gateway, the origin server and the probe client in one container.

They now reference the shared fixture's network and volumes, so there is one seed signing quotes and one set of roots derived from it, and the two cannot drift apart. `run-e2e.sh` owns the fixture's lifetime, which is why the gateways can no longer `depends_on` it. With that in place the gateways verify each other's quotes for real: `insecure_allow_external_trust_anchors` lets the anchor come from outside the vendor set, and every check in front of it runs the production path. Two fixes the run needed: `log_*` writes to stderr, so a helper whose stdout is captured no longer returns its log lines to the caller as data. Adding three ZT domains in a loop left two without certificates: the first domain on a fresh deployment creates the global ACME account and holds the shared lock while it does, and a domain added in that window is refused with "retry after it finishes" -- which nothing does. Retried here, as the error asks. The retry belongs in the product, not the harness; the suite is not the right place to fix a race it only reveals. --- .../test-run/e2e/configs/gateway-1.toml | 14 +++++ .../test-run/e2e/configs/gateway-2.toml | 14 +++++ .../test-run/e2e/configs/gateway-3.toml | 14 +++++ .../gateway/test-run/e2e/docker-compose.yml | 36 ++++++------ dstack/gateway/test-run/e2e/run-e2e.sh | 57 +++++++++++++++++-- dstack/gateway/test-run/e2e/test.sh | 54 +++++++++++------- 6 files changed, 148 insertions(+), 41 deletions(-) diff --git a/dstack/gateway/test-run/e2e/configs/gateway-1.toml b/dstack/gateway/test-run/e2e/configs/gateway-1.toml index b90efd4db..dec4e23ce 100644 --- a/dstack/gateway/test-run/e2e/configs/gateway-1.toml +++ b/dstack/gateway/test-run/e2e/configs/gateway-1.toml @@ -28,6 +28,20 @@ insecure_skip_attestation = false port = 9015 address = "0.0.0.0" +# Verify peer quotes against the development roots the mock collateral service +# derives from the simulator's seed.

The cluster suite and the e2e run were not, which is why the e2e rotted unnoticed for months and why the cluster suite still assumed a host it no longer got. Each workflow builds the gateway image, brings the attestation fixture up, runs its suite and tears everything down in a step that runs on failure too. Paths are scoped so a change to one component does not run all three.

The same twenty lines are in the gateway's sync tests, its HTTPS client tests, and `ra-rpc`'s client-auth tests, each slightly different, and none of them found `CertRequest::ca_level()` -- which has done the CA half since it was added. `wavekv_sync`'s copy shows what that costs. Because it went around `CertRequest`, it could not use `.app_id()` either, so it hand-encoded the DER OCTET STRING for the extension: debug_assert!(TEST_APP_ID.len() < 128); let mut app_id_der = vec![0x04, TEST_APP_ID.len() as u8]; Three bytes of ASN.1 header, a `debug_assert` pinning the short-form length, and a comment explaining why -- to set a field the builder already sets. Added `ra_tls::test_pki` behind an off-by-default `test-pki` feature: - `TestCa` -- a self-signed CA, `ca_level(0)` since a test CA has no reason to mint intermediates. - `TestCert` -- a leaf to mint, self-signed or CA-signed, with `.app_id()`, alt names and usage flags. `TestCert::localhost()` is the shape local TLS tests want: valid for `127.0.0.1`, usable at both ends of an mTLS connection. - `write_mtls_pki` -- CA plus one leaf, written as the `node.crt`/`node.key`/ `ca.crt` trio a client config points at. Returns both, so a test needing a second peer can sign one under the same CA. Nothing here needs a TEE: the app_id extension is an ordinary X.509 extension and a peer check that compares app ids never looks at a quote. Material that does carry attestation still goes through `generate_ra_cert_with_app_id`. The feature is off by default and reaches the gateway as a dev-dependency on the crate its normal dependency already names, so it is enabled for tests and not for the binary. `cargo tree --no-dev-dependencies` shows `ra-tls` with `default` only; with dev-dependencies it shows `test-pki`. Migrated `wavekv_sync`'s three helpers: -61/+18 lines, hand-encoded DER gone. `https_client`'s copies are left for the branch that already rewrites them. ra-tls 35 passed (31 + 4 new), dstack-gateway 308 passed, clippy and fmt clean, and `cargo build -p dstack-gateway` still builds without the feature. --- dstack/Cargo.lock | 1 + dstack/gateway/Cargo.toml | 3 + dstack/gateway/src/web_routes/wavekv_sync.rs | 79 ++--- dstack/ra-tls/Cargo.toml | 7 + dstack/ra-tls/src/lib.rs | 2 + dstack/ra-tls/src/test_pki.rs | 292 +++++++++++++++++++ 6 files changed, 323 insertions(+), 61 deletions(-) create mode 100644 dstack/ra-tls/src/test_pki.rs diff --git a/dstack/Cargo.lock b/dstack/Cargo.lock index 0ac7ac434..46f6b6727 100644 --- a/dstack/Cargo.lock +++ b/dstack/Cargo.lock @@ -5818,6 +5818,7 @@ dependencies = [ "sha2 0.10.9", "sha3", "tdx-attest", + "tempfile", "tokio", "tpm-qvl", "tpm-types", diff --git a/dstack/gateway/Cargo.toml b/dstack/gateway/Cargo.toml index 0058ec068..e682bb690 100644 --- a/dstack/gateway/Cargo.toml +++ b/dstack/gateway/Cargo.toml @@ -74,6 +74,9 @@ socket2.workspace = true [dev-dependencies] insta.workspace = true +# The test-only CA/leaf helpers.

Test names are fixed. Every run after the first therefore resumed each test on the store the same test left behind -- which is the opposite of what `docker-compose.yml` and `tests.sh` say happens. Measured, not reasoned about: with `setup_peers` stubbed so nodes never learn about each other, `test_cross_node_data_sync` passed on a second run and the suite exited 0. Node 2 found its instance already in the snapshot from the run before. With the wipe in place the same mutation fails with `kv2=0`. The same shape reaches `test_partial_cluster_bootstrap`, `test_delayed_bootnode_recovery` and the `keys_after_write > 0` guard in `test_persistence`. The clear-out runs in a throwaway root container, the way the proxy suite already does it, and removes contents only: `run` is what the suite's lock is held on, and replacing the directory would detach that lock exactly the way a deleted lock file does. Teardown is fixed alongside, because it is what leaves the state behind. `compose down` with CURRENT_TEST unset addresses `cluster-suite`, which no test ever uses -- the runner sets CURRENT_TEST before the first one -- so the `down` subcommand tore down nothing, and CI's log collection ran against a `cluster` project that has no containers. Both now ask the daemon which projects came from this compose file, so a killed run's leftovers are found whatever they are called. --- .github/workflows/gateway-cluster-tests.yml | 15 ++++-- dstack/gateway/test-run/cluster/lib.sh | 53 +++++++++++++++++++ .../test-run/cluster/run-cluster-tests.sh | 13 +++-- 3 files changed, 75 insertions(+), 6 deletions(-) diff --git a/.github/workflows/gateway-cluster-tests.yml b/.github/workflows/gateway-cluster-tests.yml index bbe0f1f5a..b354df60b 100644 --- a/.github/workflows/gateway-cluster-tests.yml +++ b/.github/workflows/gateway-cluster-tests.yml @@ -84,9 +84,18 @@ jobs: working-directory: dstack/gateway/test-run/cluster run: | mkdir -p run/logs - for svc in $(docker compose config --services); do - docker compose logs --no-color "$svc" > "run/logs/$svc.log" 2>&1 || true - done + # By project, discovered from the daemon.

Each probe forks a curl and a python3, so it costs about half again as much: a nominal 3s window measured 4.5s, and the two-probe digest loop is worse. That is not a rounding error. `test_push_fast_path` passes 3 to prove a push arrived before the 5s periodic sync could have done it anyway; the real window was ~4.8s against a 5s interval, so a dead push path was caught by the periodic round and the test still went green. Its own comment describes a bound the code did not implement. The slack cut both ways. `test_node_id_reuse_rejected` asked for 15s and passed only because it was really getting twice that: recovery there needs the rejected node's identity record to arrive in a sync *response* -- its own requests still fail the peer's inbound check -- and then an anti-entropy round to carry the store. Measured three times on an idle machine: 16s, 17s, 18s. With the timer made honest it passed one full run and failed the next, so the constant is raised to 40 with the measurement recorded next to it. `wait_for_debug` counted `sleep 1`s past a `docker compose port` and a curl, and is fixed the same way. --- dstack/gateway/test-run/cluster/lib.sh | 9 +++-- dstack/gateway/test-run/cluster/rpc.sh | 47 +++++++++++++++++------- dstack/gateway/test-run/cluster/tests.sh | 15 +++++++- 3 files changed, 53 insertions(+), 18 deletions(-) diff --git a/dstack/gateway/test-run/cluster/lib.sh b/dstack/gateway/test-run/cluster/lib.sh index c0a4d0bd4..546a522e3 100644 --- a/dstack/gateway/test-run/cluster/lib.sh +++ b/dstack/gateway/test-run/cluster/lib.sh @@ -263,9 +263,12 @@ stop_node() { wait_for_debug() { local node_id=$1 local timeout=${2:-60} - local waited=0 + # Wall clock, not an iteration count: each pass forks `docker compose port` + # and a curl, so counting `sleep 1`s overshot the stated timeout by half + # again.

Routing the script's own progress messages to stderr is not enough: git writes to stdout too. 'git checkout ' prints the branch-tracking line ('Your branch is up to date with ...') and 'git pull' prints its fast-forward summary, both on stdout. That leaves $checkout as a multi-line string, so core_dir() no longer matches and the following 'cd "$core_checkout"' fails - including on the default 'curl | sh' path, where --ref defaults to the 'next' branch. Redirect the git subshells and clones as a whole rather than adding -q per command, so a git call added later cannot reintroduce the same bug. Also use printf instead of echo in info()/error(): echo's handling of a leading '-' is implementation-defined, and dash swallows 'info "-n"' entirely. --- dstack/scripts/install.sh | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/dstack/scripts/install.sh b/dstack/scripts/install.sh index dfc27c4b2..736c18745 100755 --- a/dstack/scripts/install.sh +++ b/dstack/scripts/install.sh @@ -58,11 +58,11 @@ cleanup() { trap cleanup EXIT INT TERM info() { - echo "$*" >&2 + printf '%s\n' "$*" >&2 } error() { - echo "error: $*" >&2 + printf 'error: %s\n' "$*" >&2 } while [ "$#" -gt 0 ]; do @@ -189,26 +189,26 @@ resolve_source() { if git rev-parse --verify "origin/$ref" >/dev/null 2>&1; then git pull --ff-only origin "$ref" fi - ) + ) >&2 elif [ -n "$src" ]; then info "cloning dstack source into $src" - git clone "$repo" "$src" + git clone "$repo" "$src" >&2 ( cd "$src" git fetch --tags origin git checkout "$ref" - ) + ) >&2 else need_cmd mktemp tmp_src=$(mktemp -d "${TMPDIR:-/tmp}/dstack-install.XXXXXX") src="$tmp_src/source" info "cloning dstack source into a temporary checkout" - git clone "$repo" "$src" + git clone "$repo" "$src" >&2 ( cd "$src" git fetch --tags origin git checkout "$ref" - ) + ) >&2 fi abs_dir "$src" @@ -263,7 +263,7 @@ else install -d -m 0755 "$bin_dir" fi -echo "building dstackup from $checkout" +info "building dstackup from $checkout" ( cd "$core_checkout" cargo build --release \ From 920e8c725f7d6014a8ab889f5df787cbce85fd73 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Sat, 5 Sep 2026 04:37:19 -0700 Subject: [PATCH 1172/1246] fix(vmm/cli): look where a VMM registers, not only where it usually does A VMM registers itself in `$XDG_RUNTIME_DIR/dstack-vmm`, falling back to `/run/user//dstack-vmm` only when that variable is unset. `vmm ls` and `vmm switch` read `/run/user/*/dstack-vmm` and nothing else, so a session whose `XDG_RUNTIME_DIR` points anywhere else has a VMM that is running, reachable, and invisible to its own CLI -- reported as "No running VMM instances found", which is the one answer that is certainly wrong.

The Go lib was built and then dropped on the floor. libnvidia-container.so.1 dlopen()s libnvidia-container-go.so.1 at runtime; it is not a DT_NEEDED entry. So the omission is invisible to both ldd and "nvidia-container-cli --version", and the parity check passed because it only asserted the cli/runtime/ctk binaries, never the libraries. The failure only surfaces when the OCI runtime hook initialises a GPU container, at which point the dlopen misses: nvidia-container-cli: initialization error: load library failed: libnvidia-container-go.so.1: cannot open shared object file Install the Go lib and its SONAME symlink alongside the C lib, mirroring the existing objcopy --remove-section=.gnu_debuglink treatment for reproducibility. Also close the parity blind spot that let this ship: add both libnvidia-container.so.1 and libnvidia-container-go.so.1 to the nvidia-container required_rootfs_paths. check-parity.py follows symlinks to a real file, so a dangling SONAME (target never installed) is now caught at build finalize instead of at GPU-container start.

February 1999 + +Copyright (C) 1991, 1999 Free Software Foundation, Inc. +51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + +Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] + +Preamble + +The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. + +This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. + +When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. + +To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. + +For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. + +We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. + +To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. + +Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. + +Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. + +When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. + +We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. + +For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. + +In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. + +Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. + +The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. + +GNU LESSER GENERAL PUBLIC LICENSE +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + +0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". + +A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. + +The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) + +"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. + +Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. + +1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. + +You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. + +2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. + +(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. + +3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. + +Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. + +This option is useful when you wish to copy part of the code of the Library into a program that is not a library. + +4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. + +If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. + +5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. + +However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. + +When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. + +If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) + +Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. + +6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. + +You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: + + a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. + + e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. + +For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. + +It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. + +7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. + + b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. + +8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. + +9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. + +10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. + +11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. + +This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. + +12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. + +13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. + +14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. + +NO WARRANTY + +15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

The two callers want opposite failure policies -- the boot gate must fail closed when the inventory cannot be read, a telemetry gate wants to report no GPUs -- so the shared function returns the counts and each caller keeps its own policy on top. --- dstack/dstack-util/src/system_setup.rs | 58 ++---------- dstack/lspci/Cargo.toml | 1 + dstack/lspci/src/lib.rs | 2 + dstack/lspci/src/sysfs.rs | 118 +++++++++++++++++++++++++ 4 files changed, 126 insertions(+), 53 deletions(-) create mode 100644 dstack/lspci/src/sysfs.rs diff --git a/dstack/dstack-util/src/system_setup.rs b/dstack/dstack-util/src/system_setup.rs index 46c9d6a5f..66839b4fa 100644 --- a/dstack/dstack-util/src/system_setup.rs +++ b/dstack/dstack-util/src/system_setup.rs @@ -1361,11 +1361,7 @@ mod gpu { /// Bound Rego evaluation so a runaway application policy cannot hang boot. const POLICY_TIMEOUT: Duration = Duration::from_secs(10); - #[derive(Debug, Clone, Copy, PartialEq, Eq)] - pub(super) struct GpuInventory { - pub(super) total: u32, - pub(super) nvidia: u32, - } + use lspci::sysfs::GpuInventory; #[derive(Debug, Serialize)] struct GpuAttestationEvent { @@ -1457,33 +1453,11 @@ mod gpu { /// the NVIDIA driver did not bind cannot be hidden from the gate.

One process per sample instead of a resident helper. Nvml::init runs fresh every time, so a driver that loads after the agent started is picked up on the next sample rather than being cached as "no GPU" for the agent's lifetime. stdout is the JSON document and stderr carries the log, so the subscriber is pointed at stderr for this subcommand only. The previous in-agent helper installed no subscriber at all to protect its stdout protocol, which made every NVML warning it logged a no-op. --- dstack/Cargo.lock | 6 +- dstack/dstack-util/Cargo.toml | 2 + dstack/dstack-util/src/gpu_info.rs | 282 +++++++++++++++++++++++++++++ dstack/dstack-util/src/main.rs | 18 +- 4 files changed, 304 insertions(+), 4 deletions(-) create mode 100644 dstack/dstack-util/src/gpu_info.rs diff --git a/dstack/Cargo.lock b/dstack/Cargo.lock index 28d9862f2..89e110e04 100644 --- a/dstack/Cargo.lock +++ b/dstack/Cargo.lock @@ -2002,6 +2002,7 @@ dependencies = [ "anyhow", "base64 0.22.1", "bollard", + "cached-cell", "cc-eventlog", "cert-client", "chrono", @@ -2023,8 +2024,8 @@ dependencies = [ "libc", "listenfd", "load_config", + "lspci", "nvattest", - "nvml-wrapper", "or-panic", "ra-rpc", "ra-tls", @@ -2292,11 +2293,13 @@ dependencies = [ "ez-hash", "fs-err", "getrandom 0.3.4", + "guest-api", "hex", "hex_fmt", "host-api", "k256", "libc", + "lspci", "luks2", "nvattest", "nvml-wrapper", @@ -4292,6 +4295,7 @@ version = "0.6.0" dependencies = [ "anyhow", "insta", + "tempfile", ] [[package]] diff --git a/dstack/dstack-util/Cargo.toml b/dstack/dstack-util/Cargo.toml index ef4066831..a38f02f41 100644 --- a/dstack/dstack-util/Cargo.toml +++ b/dstack/dstack-util/Cargo.toml @@ -42,6 +42,7 @@ tpm-attest.workspace = true tpm2.workspace = true tpm-qvl = { workspace = true, features = ["crl-download"] } host-api = { workspace = true, features = ["client"] } +guest-api.workspace = true cmd_lib.workspace = true toml.workspace = true dcap-qvl.workspace = true @@ -60,6 +61,7 @@ sodiumbox.workspace = true libc.workspace = true luks2.workspace = true nvml-wrapper.workspace = true +lspci.workspace = true scopeguard.workspace = true tempfile.workspace = true ez-hash.workspace = true diff --git a/dstack/dstack-util/src/gpu_info.rs b/dstack/dstack-util/src/gpu_info.rs new file mode 100644 index 000000000..ea634b16d --- /dev/null +++ b/dstack/dstack-util/src/gpu_info.rs @@ -0,0 +1,282 @@ +// SPDX-FileCopyrightText: © 2025 Phala Network +// +// SPDX-License-Identifier: Apache-2.0 + +//!

Any GpuInfo call, any /metrics scrape, and any dashboard load -- including on apps with public_sysinfo off, where the result was rendered nowhere -- forked a helper that then stayed resident answering "no driver" forever. The PCI scan now runs once per process and every later request on such a guest is an atomic load returning a constant. A card present without the kernel module is reported as that, rather than as no GPU. /metrics never returned GPU data. The non-blocking path served a placeholder whenever the snapshot was older than the 5s TTL, which is every scrape at any realistic Prometheus interval: dstack_gpu_nvml_up 0 and no series at all on a healthy GPU. Callers now get the last snapshot whatever its age, with dstack_gpu_sample_age_seconds alongside, and the refresh happens behind them. The persistent line protocol had no cancellation safety. The RPC timeout sat 1s above the sampler's, and a future dropped between writing the request and reading the reply left the pipe desynchronised for good. One process per sample removes the state that could desynchronise. Sampling itself moves to `dstack-util gpu-info`; TtlCell replaces the hand-rolled snapshot cache, which is where get_allow_stale comes from. --- dstack/guest-agent/Cargo.toml | 5 +- dstack/guest-agent/src/gpu_info.rs | 601 ++++++++++---------- dstack/guest-agent/src/guest_api_service.rs | 4 +- dstack/guest-agent/src/http_routes.rs | 14 +- dstack/guest-agent/src/lib.rs | 1 - dstack/guest-agent/src/main.rs | 12 +- dstack/guest-agent/src/models.rs | 154 +++++ dstack/guest-agent/templates/dashboard.html | 28 +- dstack/guest-agent/templates/metrics.tpl | 99 ++-- 9 files changed, 533 insertions(+), 385 deletions(-) diff --git a/dstack/guest-agent/Cargo.toml b/dstack/guest-agent/Cargo.toml index 9ea7c51ab..9b028a6cc 100644 --- a/dstack/guest-agent/Cargo.toml +++ b/dstack/guest-agent/Cargo.toml @@ -20,7 +20,7 @@ fs-err.workspace = true rcgen.workspace = true sha2.workspace = true clap.workspace = true -tokio = { workspace = true, features = ["io-util", "process"] } +tokio = { workspace = true, features = ["process"] } hex.workspace = true serde_json.workspace = true bollard.workspace = true @@ -58,7 +58,8 @@ or-panic.workspace = true cc-eventlog.workspace = true listenfd.workspace = true libc.workspace = true -nvml-wrapper.workspace = true +cached-cell.workspace = true +lspci.workspace = true [dev-dependencies] # The test-only mock platform builds attestations from a fixture, which needs diff --git a/dstack/guest-agent/src/gpu_info.rs b/dstack/guest-agent/src/gpu_info.rs index 8a4df49b5..20b904979 100644 --- a/dstack/guest-agent/src/gpu_info.rs +++ b/dstack/guest-agent/src/gpu_info.rs @@ -2,358 +2,369 @@ // // SPDX-License-Identifier: Apache-2.0 -//!

It is not: one `dstack-util gpu-info` run, fork to exit, measures 94-99 ms on a single H200 in CC mode. Leaving the wrong reason in place invites the next reader to delete the cache once they measure it themselves. The reasons that survive the measurement are that `/metrics` carries CPU, memory, disk and container state that must not sit behind a wedged driver call, that three surfaces can scrape at once and would each fork their own collector, and that enumeration cost grows with card count where only one card has been measured. Recorded alongside the number. Also states what lazy refreshing means for freshness. A served snapshot is about one scrape interval old, not one TTL old, which is what the two live scrapes showed at 14.41 s and 19.96 s against a 5 s TTL. That is the design working, but it is not what the constant's name suggests, and a consumer aligning these series with a host-side exporter needs to know the offset is there. --- dstack/guest-agent/src/gpu_info.rs | 50 ++++++++++++++++++++++++------ 1 file changed, 41 insertions(+), 9 deletions(-) diff --git a/dstack/guest-agent/src/gpu_info.rs b/dstack/guest-agent/src/gpu_info.rs index 0bbe96cd1..19dc12fd8 100644 --- a/dstack/guest-agent/src/gpu_info.rs +++ b/dstack/guest-agent/src/gpu_info.rs @@ -14,10 +14,36 @@ //! short-lived child that can be killed when a driver call wedges.

The GPU tests reach into three process-global values -- the snapshot cell, the refresh lock and the collector override -- while the harness runs them on parallel threads, so they were racing each other rather than exercising the code. Two collisions, not one. Two tests took the refresh lock with try_lock and panicked when they lost, which is the failure CI reported. A third set the collector override without holding anything, so it could point the hanging-collector test at a nonexistent path, or be pointed by it at a stub that sleeps for a minute. One guard now covers all three tests, waits instead of failing when it has to, and clears the collector override on the way out so a stub cannot leak past the test that installed it. Reproduced the original panic 4 times in 60 runs at 16 threads; the fixed tests survive 120. --- dstack/guest-agent/src/gpu_info.rs | 48 +++++++++++++++++++++++++----- 1 file changed, 41 insertions(+), 7 deletions(-) diff --git a/dstack/guest-agent/src/gpu_info.rs b/dstack/guest-agent/src/gpu_info.rs index 19dc12fd8..6e62a9641 100644 --- a/dstack/guest-agent/src/gpu_info.rs +++ b/dstack/guest-agent/src/gpu_info.rs @@ -309,12 +309,45 @@ fn unavailable(error: impl Into) -> GpuInfoResponse { mod test_support { use super::*; - pub(super) fn set_snapshot(response: GpuInfoResponse) { - SNAPSHOT.set(response); + /// Serializes the tests that reach into process-global state. + /// + /// [`SNAPSHOT`], [`REFRESH_LOCK`] and [`COLLECTOR_OVERRIDE`] are one per + /// process while the harness runs tests on parallel threads, so without + /// this two tests race over the same cache entry and the same collector + /// path -- one pointing at a stub that sleeps, the other at a path that + /// does not exist. + static EXCLUSION: LazyLock> = LazyLock::new(|| Mutex::new(())); + + /// Held for the whole test body, not just the mutation, and restores the + /// collector override on the way out so a stub cannot leak into a test + /// that expects the real path. + pub(super) struct Exclusive { + _exclusion: tokio::sync::MutexGuard<'static, ()>, + _refresh: tokio::sync::MutexGuard<'static, ()>, + } + + impl Drop for Exclusive { + fn drop(&mut self) { + *COLLECTOR_OVERRIDE + .write() + .or_panic("collector override poisoned") = None; + } } - pub(super) fn hold_refresh_lock() -> tokio::sync::MutexGuard<'static, ()> { - REFRESH_LOCK.try_lock().expect("refresh lock is free") + pub(super) async fn exclusive() -> Exclusive { + let exclusion = EXCLUSION.lock().await; + // Waits rather than try_lock: a refresh spawned by an earlier test may + // still be finishing, and failing a test for losing that race tests + // the harness rather than the code. + let refresh = REFRESH_LOCK.lock().await; + Exclusive { + _exclusion: exclusion, + _refresh: refresh, + } + } + + pub(super) fn set_snapshot(response: GpuInfoResponse) { + SNAPSHOT.set(response); } pub(super) fn set_collector(path: &str) { @@ -377,9 +410,9 @@ mod tests { /// `/metrics` reported zero GPUs forever at Prometheus' default 15s. #[tokio::test] async fn a_snapshot_older_than_the_ttl_is_still_served() { - // Hold the refresh lock so the spawned refresh cannot overwrite the + // Hold the globals so no refresh, and no other test, can overwrite the // snapshot mid-assertion on a machine that does have a GPU. - let _guard = test_support::hold_refresh_lock(); + let _guard = test_support::exclusive().await; test_support::set_snapshot(sample_response()); let served = serve(SNAPSHOT.get_allow_stale().ok()); @@ -408,7 +441,7 @@ mod tests { std::fs::set_permissions(&script, std::fs::Permissions::from_mode(0o755)) .expect("chmod stub"); - let _guard = test_support::hold_refresh_lock(); + let _guard = test_support::exclusive().await; test_support::set_collector(&script.to_string_lossy()); let outcome = timeout(Duration::from_millis(500), collect()).await; @@ -434,6 +467,7 @@ mod tests { /// a panic and not a silent "no GPUs". #[tokio::test] async fn a_missing_collector_is_reported_as_an_error() { + let _guard = test_support::exclusive().await; test_support::set_collector("/nonexistent/dstack-util"); let error = collect().await.expect_err("must fail"); assert!( From b6efabe7544476fc1b9e933863038caac88061e9 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Sun, 6 Sep 2026 21:08:20 -0700 Subject: [PATCH 1188/1246] fix(guest-agent): make the dashboard GPU section readable The section rendered as two bare paragraphs on a page where every other block is a card, and put its values in the shape the wire uses rather than the shape a reader uses. Four things. The confidential-computing state and the sample age move into the label/value rows the rest of the page is built from, so the section stops looking unstyled. The age is rounded to one decimal, like the wattage beside it, instead of printing a raw f32. The UUID column is gone: it is forty characters that pushed every other cell into wrapping, and a reader who needs it has `/metrics` and the `GpuInfo` RPC. The PCI address drops a zero domain, because NVML writes `00000000:01:00.0` where lspci and the kernel write `01:00.0`. Both shortenings are display-only. `/metrics` still carries the full UUID and the full bus ID, because those labels are what a host-side exporter joins these series against, and a test now says so.

Three backgrounds to show one string, and the innermost one reads as a disabled text input, which is a claim the page cannot honour -- none of these values are editable. The card stays and the two inner boxes become a hairline between rows. With rows separating themselves the 12px grid gap is redundant, and the 1.6 line-height is a prose setting on a page that is entirely single-line data. Headings were spending about seventy pixels each on margins. A row goes from roughly 60px to 34px. Tables had the opposite problem in the same place: 15px cells made rows tall while the columns stayed too narrow to hold an identifier, so a single GPU row wrapped into three lines of text. Cells shrink, values stop wrapping, and the table scrolls sideways when it has to. That scrolling goes on a wrapper. Setting overflow on the table itself needs display:block, which drops the table formatting context and lets thead and tbody compute their widths independently -- the header bar and the body rows then disagree about where the right edge is. The wrapper also owns the rounded corners and the shadow now, which deletes the four per-corner rules that were placing them on individual cells. --- dstack/guest-agent/templates/dashboard.html | 259 ++++++++++---------- 1 file changed, 134 insertions(+), 125 deletions(-) diff --git a/dstack/guest-agent/templates/dashboard.html b/dstack/guest-agent/templates/dashboard.html index e4eccda03..d026cbe9e 100644 --- a/dstack/guest-agent/templates/dashboard.html +++ b/dstack/guest-agent/templates/dashboard.html @@ -21,9 +21,10 @@ body { font-family: 'Segoe UI', system-ui, -apple-system, sans-serif; - line-height: 1.6; - padding: 30px; - max-width: 1000px; + /* Data, not prose: 1.6 leading on single-line values reads as gaps. */ + line-height: 1.45; + padding: 24px 20px; + max-width: 1180px; margin: 0 auto; background-color: var(--background-color); color: var(--primary-color); @@ -32,9 +33,18 @@ h1, h2 { color: var(--primary-color); - margin-bottom: 1rem; border-bottom: 2px solid var(--border-color); - padding-bottom: 0.5rem; + padding-bottom: 0.3rem; + } + + h1 { + font-size: 1.6rem; + margin: 0 0 0.6rem; + } + + h2 { + font-size: 1.15rem; + margin: 1.4rem 0 0.6rem; } textarea { @@ -49,45 +59,43 @@ resize: vertical; } + /* Overflow belongs on a wrapper.

It now renders as `1m 8s`. `Load Average` printed `1min: 0.4%`. The wire carries the load times 100, so the page divided it back and then appended a `%`. A load average is a count of runnable tasks, not a percentage: `1.00` on a single-core guest means saturated, not one percent. `/metrics` had the same field wrong in the opposite direction and worse. `dstack_guest_load1` published the undivided integer, so a load of 0.40 was served as `40` under a gauge whose HELP text says "System load average over 1 minute" -- two orders of magnitude off, to a consumer that cannot notice. The deprecated `system_load_average_*` aliases carried the same error. Both now divide. Also scopes the link padding inside table cells. The global `a` rule gives the hover pill 6px of vertical padding, which in a cell sets the row height, so once the cells themselves are tight the one row holding a "View Logs" link stands taller than every other row.

QEMU commit a7542a38f399 ("x86/loader: Don't update kernel header for CoCo VMs", first released in 10.2.0) stopped rewriting the header for confidential guests, so the same kernel measures differently depending on which QEMU the host runs -- and the host is the one that declares that version. Remove the dependency for images built from now on. The image build zeroes those fields in the kernel it ships and records `"kernel_header_normalized": true` in metadata.json; OVMF zeroes them again before the kernel blob is measured and loaded. RTMR[1] is then the plain Authenticode hash of the bzImage in sha256sum.txt, on every QEMU version and at every guest memory size, which also lifts the `memory_size == 2 GiB || >= 0xB0000000` restriction on the no-image-download path. Existing images are untouched. Their firmware does not normalize, so their digest still covers QEMU's rewritten copy, and `dstack-mr` keeps measuring them that way -- byte for byte the same measurement document, so `os_image_hash` and every on-chain whitelist entry stay valid. Which behavior applies is declared by the image, never by the host, and both verification paths read it: the image-download path from metadata.json via `ImageInfo`, the no-image-download path from the flag mirrored into the measurement document. The flag is omitted when false, so pre-normalization documents encode exactly as they always did and the document version does not move. The normalized field set comes from the boot protocol rather than from QEMU: every field Documentation/arch/x86/boot.rst types as `write` is one the boot loader fills in and the kernel supplies no value for. Fields typed `modify` carry real kernel-supplied values -- code32_start is the protected-mode entry point -- and are left alone. In practice this rewrites two bytes. heap_end_ptr is the only `write` field a built kernel leaves non-zero, and it is read only when the boot loader has set CAN_USE_HEAP, which the kernel builds clear and this also clears. On the EFI-stub path the real-mode setup code never runs, and no setup-header field overlaps the PE headers at 0x40..0x170. --- docs/security/security-model.md | 39 +++++ dstack/dstack-mr/cli/src/main.rs | 2 + dstack/dstack-mr/src/kernel.rs | 76 ++++++++- dstack/dstack-mr/src/machine.rs | 7 + dstack/dstack-mr/src/tdx.rs | 66 +++++--- dstack/dstack-types/src/lib.rs | 134 ++++++++++++++- dstack/verifier/src/verification.rs | 80 +++++++++ dstack/vmm/src/app.rs | 1 + os/image/README.md | 51 ++++++ os/image/assemble.sh | 17 +- os/image/normalize-kernel-header.py | 130 +++++++++++++++ os/mkosi/components/ovmf/ovmf-build.sh | 3 +- os/mkosi/components/ovmf/ovmf.sh | 3 +- ...elLoaderFsDxe-normalize-setup-header.patch | 156 ++++++++++++++++++ .../dstack-ovmf/dstack-ovmf_git.bb | 6 + 15 files changed, 738 insertions(+), 33 deletions(-) create mode 100755 os/image/normalize-kernel-header.py create mode 100644 os/yocto/layers/meta-dstack/recipes-core/dstack-ovmf/dstack-ovmf/0007-OvmfPkg-QemuKernelLoaderFsDxe-normalize-setup-header.patch diff --git a/docs/security/security-model.md b/docs/security/security-model.md index 5a0491867..751dbdc79 100644 --- a/docs/security/security-model.md +++ b/docs/security/security-model.md @@ -317,6 +317,45 @@ AML access to encrypted/private guest RAM.

The dstack image build applies +the same normalization to the kernel it ships, so the measurement is the plain +Authenticode hash of that file on every QEMU version. + +The field set is taken from Documentation/arch/x86/boot.rst rather than from +QEMU's behavior: fields typed `write` are ones the boot loader fills in and the +kernel supplies no value for. Fields typed `modify` are left alone because they +carry real kernel-supplied values. + +Booting is unaffected. On the EFI-stub path the real-mode setup code never +runs, and heap_end_ptr -- the only one of these fields a built kernel leaves +non-zero -- is read only when the boot loader has set CAN_USE_HEAP, which this +also clears. + +Signed-off-by: dstack +--- +--- a/OvmfPkg/QemuKernelLoaderFsDxe/QemuKernelLoaderFsDxe.c ++++ b/OvmfPkg/QemuKernelLoaderFsDxe/QemuKernelLoaderFsDxe.c +@@ -49,6 +49,111 @@ + KERNEL_BLOB *Next; + }; + ++// ++// Offsets into the Linux x86 setup header, from ++// Documentation/arch/x86/boot.rst. ++// ++#define LINUX_HDR_MAGIC_OFFSET 0x202 ++#define LINUX_HDR_VERSION_OFFSET 0x206 ++#define LINUX_HDR_LOADFLAGS_OFFSET 0x211 ++#define LINUX_HDR_END_OFFSET 0x258 ++ ++// ++// CAN_USE_HEAP in loadflags.

b44816faee06c565c703e3f540f05ebb5d7c0166 Mon Sep 17 00:00:00 2001 From: Kevin Wang Date: Tue, 8 Sep 2026 10:29:32 +0800 Subject: [PATCH 1199/1246] fix(os): let the SWIOTLB bounce buffer grow at runtime (#1192) Every DMA in a CVM is bounced through SWIOTLB, because the host cannot reach the guest's private memory, and both guest kernels shipped with CONFIG_SWIOTLB_DYNAMIC off. The pool a guest gets at boot is therefore the only pool it ever gets, sized by arch/x86/mm/mem_encrypt.c at 6% of RAM clamped to 1 GiB. Bursty virtio traffic runs it dry: virtio-pci 0000:00:02.0: swiotlb buffer is full (sz: 262144 bytes), total 524288 (slots), used 523564 (slots) 524288 slots is that 1 GiB cap, 262144 bytes is IO_TLB_SIZE * IO_TLB_SEGSIZE, the largest mapping swiotlb can serve at all. The mapping fails with -ENOMEM and the caller reports dropped packets or block I/O errors, so nothing on the path to the operator names SWIOTLB. Raising the pool with a swiotlb= command line argument was the alternative and is worse on three counts. The command line is measured into the RTMRs and has to stay in step across dstack-uki.bb and os/image/kernel-cmdline.sh, for a value that can only guess at the peak. The boot pool has to fit below 4 GiB regardless: the x86 KVM path never sets SWIOTLB_ANY (only Xen does, in arch/x86/kernel/pci-dma.c), so swiotlb_memblock_alloc() takes the memblock_alloc_low() branch. And swiotlb_init_remap() halves a request it cannot satisfy and carries on, so a larger value is not even reliably granted. Pools allocated at runtime are bounded by the device's DMA mask instead, which for virtio is 64-bit. The cost falls on the unmap and sync paths, where swiotlb_find_pool() stops being an inline range check against the single pool and becomes an RCU walk of the pool list. The synchronous allocation path also needs CONFIG_DMA_COHERENT_POOL, since force_dma_unencrypted() is true here and GFP_NOWAIT cannot block; CONFIG_AMD_MEM_ENCRYPT already selects it, confirmed =y in the built config. Asserted in parity.json so the mkosi fragment cannot drift from the Yocto one, on top of check-kernel-config.sh, which both backends already run against their fragments and which turns each of these lines into a build-time assertion. --- os/mkosi/components/kernel/kernel.config | 26 +++++++++++++++++++ os/mkosi/parity.json | 1 + .../recipes-kernel/linux/files/dstack.cfg | 25 ++++++++++++++++++ 3 files changed, 52 insertions(+) diff --git a/os/mkosi/components/kernel/kernel.config b/os/mkosi/components/kernel/kernel.config index 706a33d36..822e539b9 100644 --- a/os/mkosi/components/kernel/kernel.config +++ b/os/mkosi/components/kernel/kernel.config @@ -37,6 +37,32 @@ CONFIG_VSOCKETS=y CONFIG_NET_9P=y CONFIG_NET_9P_VIRTIO=y CONFIG_9P_FS=y + +# Let the SWIOTLB bounce buffer grow at runtime.

Race the build itself against the shutdown signal, matching the daemon-loop select already in place. Also replace unreachable!("certbot daemon returned") with a normal error exit. The panic only held because CertBot::run() happens to be an unconditional loop today; it was not enforced by the type system, so a future early return from run() would have turned into a panic with a misleading message instead of a clean error.

Rebuilding the measured command line by hand at each site is how RTMR[2] and the SNP MEASUREMENT drift apart without anyone noticing. - Extract `tdx::OVMF_INITRD_CMDLINE_SUFFIX` and route the verifier, the CLI and the TDVF test through `tdx::measured_kernel_cmdline`. - Rename the SNP helper to `normalize_kernel_cmdline` and document why the two are not interchangeable. - Correct two comments crediting a `kernel_cmdline_sha256` field that does not exist; the rootfs identity is committed by the `base_cmdline` string. - Pin the RTMR[2] command-line event digest, the RTMR[2] replay and the `measurement.tdx.cbor` encoding with golden vectors, so a change to the measurement protocol has to be an explicit, reviewed edit rather than a side effect.

A digest is one-way: it cannot be reported to a relying party, and it cannot be re-derived if anything about the command line ever needs to vary. AMD SEV-SNP already carries the string; TDX was the outlier. Replace the digest with the image-provided command line and bump the document to version 4. Version 3 only ever shipped in v0.6.0 release candidates, so it is rejected outright rather than carried forward; the error tells the operator to rebuild the image and re-register its os_image_hash. The measured command line is unchanged, so this is purely a change of representation: the RTMR[2] golden vectors added in the previous commit still pass untouched, and only the CBOR encoding vector moved. Two things fall out of holding the string: - The no-download path can now enforce the same `dstack.rootfs_hash` invariant the build path does, instead of trusting an opaque 48 bytes. - The verifier can report the effective command line rather than a hash. The two normalized TDX lite fixtures are re-encoded to version 4. Their captured quotes and event logs are untouched: `measurement.tdx.cbor` is derived from the image by dstack-mr rather than captured, and the command line used to rebuild it is confirmed by reproducing the version 3 digest exactly. `sha256sum.txt` and `os_image_hash` move with it, as they must. --- dstack/dstack-mr/src/tdx.rs | 26 +++++++------- dstack/dstack-types/src/lib.rs | 36 ++++++++++++------- .../tdx-lite-normalized-attestation.json | 2 +- ...lite-normalized-qemu-10-2-attestation.json | 2 +- dstack/vmm/src/app.rs | 2 +- 5 files changed, 38 insertions(+), 30 deletions(-) diff --git a/dstack/dstack-mr/src/tdx.rs b/dstack/dstack-mr/src/tdx.rs index 9f8657a4c..72e29f405 100644 --- a/dstack/dstack-mr/src/tdx.rs +++ b/dstack/dstack-mr/src/tdx.rs @@ -326,8 +326,8 @@ pub fn tdx_os_image_measurement_for_image_dir(image_dir: &Path) -> Result<TdxOsI // Validate that the image identity carried by the measured cmdline is // well-formed.

00:17:48 -0700 Subject: [PATCH 1213/1246] test(verifier): recapture the pre-normalization TDX lite fixtures The measurement document these carry is version 3, which stores the kernel command line as a digest. Version 4 needs the string, and a digest cannot be turned back into one, so unlike the two normalized fixtures -- whose command line was recovered and confirmed against their version 3 digest -- this pair had to come from a fresh boot. Recaptured from a pre-normalization image taken as built. The build system hardcodes `kernel_header_normalized: true` and fails when the OVMF patch does not apply, so it can no longer produce the image this pair exercises; only the derived measurement material was regenerated with the current dstack-mr, which is why `os_image_hash` moved. The capture keeps every property the tests rely on: `lite` variant, 2 GiB, an absent `kernel_header_normalized`, and RTMR0 `ACPI DATA` digests that the verifier reproduces in-process from the VM shape. Taken from a real TDX CVM on QEMU 8.2.2 with no key provider, via an app-compose prelaunch script calling the guest agent's `GetQuote` and `Attest`. The README records the procedure so the next document version does not have to rediscover it. --- .../fixtures/tdx-lite-attestation.json | 2 +- .../verifier/fixtures/tdx-lite-getquote.json | 8 ++--

That came from QEMU's setup-header rewrite, which moves the initrd with guest RAM and so makes the patched kernel Authenticode hash memory-dependent. Images whose OVMF normalizes the setup header measure the shipped `bzImage` instead, which no guest RAM size can move -- and that is every image the build system can now produce: `os/image/assemble.sh` hardcodes `kernel_header_normalized` and the OVMF build fails when the normalization patch does not apply. So the heuristic now only costs deployments the cheaper verification path: a 1 GiB CVM on a current image got legacy despite carrying everything lite needs. Drop it and follow `image_supports_lite` alone; `resolve` no longer takes the memory size. A pre-normalization image is the one case this stops covering. The no-download verifier still rejects those below the threshold, with an error that names the memory sizes and says to re-emit the image, so the failure is explicit rather than a silent mismatch, and `tdx_attestation_variant = "legacy"` keeps one running as is. --- dstack/vmm/src/app.rs | 12 +++---- dstack/vmm/src/config.rs | 69 +++++++++++++++++++--------------------- dstack/vmm/vmm.toml | 6 ++-- 3 files changed, 42 insertions(+), 45 deletions(-) diff --git a/dstack/vmm/src/app.rs b/dstack/vmm/src/app.rs index baa947078..959aebec9 100644 --- a/dstack/vmm/src/app.rs +++ b/dstack/vmm/src/app.rs @@ -1734,7 +1734,7 @@ fn make_vm_config( tdx_attestation_variant_from_requirements(requirements).unwrap_or_else(|| { cfg.cvm .tdx_attestation_variant - .resolve(manifest.memory, image_supports_tdx_lite(image)) + .resolve(image_supports_tdx_lite(image)) }) } else { dstack_types::TdxAttestationVariant::Legacy @@ -2565,17 +2565,17 @@ mod tests { Ok(()) } + /// 1 GiB used to fall back to legacy: it is below 3 GiB and not the 2 GiB + /// exemption.

The flag existed only because config load wrote the detected version back into `qemu_version`, conflating "configured" with "detected". Drop the load-time detection instead: `qemu_version` then means an explicit override and nothing else, the flag is unnecessary, and one-shot mode needs no special case. A version that can be neither detected nor configured now fails the start with a message asking for `qemu_version` in vmm.toml.

Only the first line of stdout was parsed, so such a wrapper failed detection -- which now fails the start. Search every line of stdout and stderr for QEMU's own wording ("QEMU emulator version X"), and stop guessing at version-shaped words when it is absent: once every line is searched, a guess would read a version out of the banner (`qemu-kvm-8.2.0`), and a wrong version boots a CVM that cannot be attested.

The `tcb_info` JSON blob is gone: its measurement values are typed top-level fields that each appear exactly once, and the documents it nested (`app_compose`, `vm_config`) are served directly instead of through two layers of JSON parsing. MRTD, RTMR0-3 and the event log are deliberately absent -- they are attestation data, and `Info` handing out unattested copies invited relying parties to trust values nothing vouched for. Ask `Attest` and verify. The demo `app_cert` is dropped as well - guest-agent: `AttestGpu` collects vendor-native GPU evidence on demand against a caller-supplied 32-byte nonce. It returns opaque, versioned evidence bundles identified by vendor and format for independent appraisal, and the response format is extensible to additional GPU vendors. v1 only - guest-agent: v1 `Attest` accepts `include_boottime_gpu_evidence` and returns the boot-time GPU attestation evidence in `AttestResponse.boottime_gpu_evidence`, so a verifier fetches the attestation and the GPU evidence in one round trip. It arrives as a `GpuEvidenceBundle` list -- the same shape `AttestGpu` returns, so a consumer writes one bundle parser and dispatches on `format`: `nvidia-nvattest-boottime-json-v1` is the record written at boot, `nvidia-nvattest-collect-evidence-json-v1` is collected on demand against a caller's nonce, and a verifier for one does not appraise the other. Absence is the empty list. The bundle's `evidence` is the nvattest output byte for byte as read from disk, because the only thing binding it to the boot is sha256 over precisely those bytes against the measured `gpu-attestation` event. `Attest` is also v1's sole CVM attestation entry point: the `VersionedAttestation` it returns already carries the TDX quote and event log, and unlike `GetQuote` it answers on every supported platform +- guest-agent: v1 `Attest` and `IssueCert` always use the MessagePack V1 attestation schema. `Attest` returns it, and `IssueCert` puts it in the CSR, which the signer embeds in the RA-TLS certificate in the same form. Until now the encoding followed the attestation's contents: a TDX CVM whose runtime events were all V1 got the legacy SCALE form, and one with V2 events or a pod payload got MessagePack. That left every v1 client implementing two decoders for a surface that has no released client to stay compatible with. The frozen v0 `Attest` and `GetTlsKey` keep the content-dependent choice: relying parties before 0.5.9 decode only SCALE, and KMS onboarding embeds v0 `Attest` bytes in the certificate an older source KMS verifies. **Requires 0.5.9 or later** of the KMS signing a v1 `IssueCert` CSR and of anything verifying a v1 `Attest` result or a v1-issued RA-TLS certificate - sdk: `AppCompose` in the Go SDK gained `init_script`, `storage_fs`, `swap_size`, `event_log_version`, `port_policy` and `verity_volumes`, and `Requirements` gained `gpu_policy` in the Go and Python SDKs - shared API authentication (`dstack-api-auth`) protecting the full VMM HTTP/pRPC/UI surface and unifying Gateway/KMS admin auth: bearer/`X-Admin-Token`/HTTP Basic/bcrypt htpasswd, constant-time verification (#796) - certbot/gateway: opt-in `dns-persist-01` certificate validation ([draft-ietf-acme-dns-persist-01](https://datatracker.ietf.org/doc/html/draft-ietf-acme-dns-persist-01)), which issues without a DNS provider credential at all. `dns-01` needs write access to the zone on every order, so a gateway CVM holds a Cloudflare API token for the life of the deployment -- a token that rewrites the whole zone, not just `_acme-challenge`. Under `dns-persist-01` the zone owner publishes one `_validation-persist.<name>` TXT record naming the CA and the ACME account; nothing about it changes between orders, so certbot only ever reads DNS and the zone can be hosted anywhere, with no provider integration. Set `challenge = "dns-persist-01"` in `certbot.toml`, or `challenge` on a gateway ZT domain; the default stays `dns-01` and existing deployments are untouched. `certbot dns-records` prints the records to publish, `GetZtDomain`/`ListZtDomains` return them in `required_dns_records`, and the gateway logs them wherever it would otherwise have written DNS. CAA records carry `validationmethods=dns-persist-01` to match, so switching methods means republishing both. Two gateway operations change shape for such a domain: `SetCaa` skips it, having nothing to reconcile without write access, and `RotateAcmeCredentials` leaves it broken until the operator republishes -- the record still names the old account -- so the response now returns the new records in `required_dns_records`. A rotation that registers the account but fails to re-pin some domain's CAA now reports those domains in `repin_failed_domains` instead of failing the call: the account exists and the cluster is using it, so raising an error there reads as "nothing happened" and invites a retry that registers another account. **Experimental**: the draft is still changing, and Let's Encrypt serves the challenge on staging only pending an open working-group issue.

Saying only "deprecated, will be removed" invites deleting that tree or skipping edits to files that are live inputs of the default image. State the dependency wherever the deprecation is. Also correct statements that no longer hold with mkosi as the default: the source-boundary description (mkosi mounts the whole repository as an ephemeral build source), the AWS runbook's "os/build.sh produces the archive" (a cached native mkosi build skips tarballs), the -o DIR hint that make os-image cannot take, the missing root requirement for native builds, and a leftover "experimental" comment in versions.env. --- CHANGELOG.md | 2 +- CLAUDE.md | 3 ++- docs/aws-ec2-production-verifier-runbook.md | 8 ++++---- docs/building-guest-os.md | 20 +++++++++++++------- os/README.md | 18 +++++++++++++++--- os/mkosi/versions.env | 2 +- os/yocto/README.md | 10 ++++++++++ 7 files changed, 46 insertions(+), 17 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index c1a13f998..736c279cc 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -89,7 +89,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0 ### Deprecated -- os: the Yocto guest-OS backend (`os/yocto/`) is deprecated in favor of mkosi (`os/mkosi/`), which is now the default and recommended backend. `os/build.sh` defaults to `--backend mkosi`, and `make os-image` / `make os-repro-check` build with mkosi.

When the snapshot service is flaky (e.g. 503 No healthy backends), apt-get update only warns about indexes it failed to fetch and exits 0. If the security index is the one that failed, apt silently installs older versions from the main suite and the build later fails in verify-pinned-packages.sh with a misleading "regenerate pinned packages" diff. Pass -o APT::Update::Error-Mode=any so a failed index fetch aborts the build right away with the real cause. --- dstack/gateway/dstack-app/builder/Dockerfile | 4 ++-- dstack/kms/dstack-app/builder/Dockerfile | 4 ++-- dstack/verifier/builder/Dockerfile | 4 ++-- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/dstack/gateway/dstack-app/builder/Dockerfile b/dstack/gateway/dstack-app/builder/Dockerfile index 42a78560f..a4446a7d9 100644 --- a/dstack/gateway/dstack-app/builder/Dockerfile +++ b/dstack/gateway/dstack-app/builder/Dockerfile @@ -9,7 +9,7 @@ ARG DSTACK_REV ARG DSTACK_SRC_URL=https://github.com/Dstack-TEE/dstack.git WORKDIR /build RUN ./pin-packages.sh ./builder-pinned-packages.txt -RUN apt-get update && \ +RUN apt-get update -o APT::Update::Error-Mode=any && \ apt-get install -y --no-install-recommends \ git \ build-essential \ @@ -31,7 +31,7 @@ COPY --from=build-shared pin-packages.sh /build/ COPY ./shared/pinned-packages.txt /build/ WORKDIR /build RUN ./pin-packages.sh ./pinned-packages.txt && \ - apt-get update && \ + apt-get update -o APT::Update::Error-Mode=any && \ apt-get install -y --no-install-recommends \ git \ wireguard-tools \ diff --git a/dstack/kms/dstack-app/builder/Dockerfile b/dstack/kms/dstack-app/builder/Dockerfile index 91d9e0a04..ec4e73f10 100644 --- a/dstack/kms/dstack-app/builder/Dockerfile +++ b/dstack/kms/dstack-app/builder/Dockerfile @@ -9,7 +9,7 @@ ARG DSTACK_REV ARG DSTACK_SRC_URL=https://github.com/Dstack-TEE/dstack.git WORKDIR /build RUN ./pin-packages.sh ./builder-pinned-packages.txt -RUN apt-get update && \ +RUN apt-get update -o APT::Update::Error-Mode=any && \ apt-get install -y --no-install-recommends \ git \ build-essential \ @@ -35,7 +35,7 @@ WORKDIR /build # and AMD KDS clients eagerly at startup, so a base image without CA # certificates fails to boot before it serves anything.

The `-netdev` half carries `vhost=on|off` either way, since that is what selects the backend. ## Requirements diff --git a/dstack/scripts/setup-bridge.sh b/dstack/scripts/setup-bridge.sh index edcbe35a7..ecc3d2901 100755 --- a/dstack/scripts/setup-bridge.sh +++ b/dstack/scripts/setup-bridge.sh @@ -44,83 +44,6 @@ run_cmd() { fi } -# --- Detect qemu-bridge-helper path --- - -find_bridge_helper() { - local paths=( - /usr/lib/qemu/qemu-bridge-helper - /usr/libexec/qemu-bridge-helper - /usr/local/lib/qemu/qemu-bridge-helper - /usr/local/libexec/qemu-bridge-helper - ) - for p in "${paths[@]}"; do - if [[ -f "$p" ]]; then - echo "$p" - return 0 - fi - done - return 1 -} - -# --- Detect current bridge provider --- - -# Returns "libvirt:<net_name>" if bridge is managed by a libvirt network, -# "standalone" otherwise. -detect_bridge_provider() { - if command -v virsh &>/dev/null; then - local name br - while read -r name; do - [[ -z "$name" ]] && continue - br=$(virsh net-dumpxml "$name" 2>/dev/null | grep -oP "<bridge name='\K[^']*" | head -1 || true) - if [[ "$br" == "$BRIDGE" ]]; then - echo "libvirt:$name" - return 0 - fi - done < <(virsh net-list --all --name 2>/dev/null) - fi - echo "standalone" -} - -# --- Check functions --- - -check_bridge_helper() { - echo - bold "qemu-bridge-helper" - local helper - if ! helper=$(find_bridge_helper); then - check_fail "qemu-bridge-helper not found" - check_info "Install QEMU: sudo apt install qemu-system-x86" - return - fi - check_pass "found at $helper" - - if [[ -u "$helper" ]]; then - check_pass "setuid bit is set" - else - check_fail "setuid bit not set" - check_info "Fix: sudo chmod u+s $helper" - fi -} - -check_bridge_conf() { - echo - bold "/etc/qemu/bridge.conf" - local conf="/etc/qemu/bridge.conf" - if [[ ! -f "$conf" ]]; then - check_fail "$conf does not exist" - check_info "Fix: sudo mkdir -p /etc/qemu && echo 'allow $BRIDGE' | sudo tee $conf" - return - fi - check_pass "$conf exists" - - if grep -qE "^allow[[:space:]]+($BRIDGE|all)[[:space:]]*$" "$conf" 2>/dev/null; then - check_pass "bridge '$BRIDGE' is allowed" - else - check_fail "bridge '$BRIDGE' not found in $conf" - check_info "Fix: echo 'allow $BRIDGE' | sudo tee -a $conf" - fi -} - check_bridge_interface() { echo bold "bridge interface: $BRIDGE" @@ -326,33 +249,6 @@ check_forward_rules() { # --- Setup: common --- -setup_bridge_conf() { - echo - bold "Setting up /etc/qemu/bridge.conf" - run_cmd sudo mkdir -p /etc/qemu - if [[ -f /etc/qemu/bridge.conf ]] && grep -qE "^allow[[:space:]]+($BRIDGE|all)" /etc/qemu/bridge.conf 2>/dev/null; then - echo " already configured" - else - run_cmd bash -c "echo 'allow $BRIDGE' | sudo tee -a /etc/qemu/bridge.conf" - fi -} - -setup_bridge_helper() { - echo - bold "Setting up qemu-bridge-helper" - local helper - if ! helper=$(find_bridge_helper); then - echo " $(red 'ERROR'): qemu-bridge-helper not found.

Drop the override so containers can use the CPU limits users ask for. The mkosi images never carried this pin, so both OS backends now behave the same.

The layers it could reuse, the pinned-package install and rustup, take about fifteen seconds.

Define the protocol in `netd_rpc.proto` instead: `PrepareBridge`, `PrepareMacvtap`, `RemoveInterface` and `CheckInterface` each have their own request and response messages. netd serves the generated `NetdServer` with Rocket and ra-rpc on the same Unix socket (bound itself or handed over by systemd), and the VMM calls it through the generated `NetdClient`. The hand-written framing, size limits, liveness-probe handling and the tagged request/response types go away. Operations still run one at a time: a FIFO async mutex keeps them in arrival order, which the VMM's rollback after a timed-out Prepare relies on, and the flock still serializes against other netd processes. `PrpcClient` now includes the server's `{"error": ...}` message when a call fails, so netd's reason for refusing a request reaches the VMM log instead of only a status code. This is a wire-protocol break: the VMM and netd must come from the same release, and `dstack-netd` has to be restarted together with the VMM. --- docs/libvirt-network-filter.md | 19 +- dstack/Cargo.lock | 14 + dstack/Cargo.toml | 2 + dstack/http-client/src/prpc.rs | 29 +- dstack/vmm/Cargo.toml | 2 + dstack/vmm/netd-rpc/Cargo.toml | 20 + dstack/vmm/netd-rpc/build.rs | 17 + dstack/vmm/netd-rpc/proto/netd_rpc.proto | 70 ++ dstack/vmm/netd-rpc/src/generated/mod.rs | 6 + dstack/vmm/netd-rpc/src/lib.rs | 12 + dstack/vmm/src/app.rs | 108 ++- dstack/vmm/src/app/qemu.rs | 2 +- dstack/vmm/src/netd.rs | 806 ++++++++++------------- 13 files changed, 575 insertions(+), 532 deletions(-) create mode 100644 dstack/vmm/netd-rpc/Cargo.toml create mode 100644 dstack/vmm/netd-rpc/build.rs create mode 100644 dstack/vmm/netd-rpc/proto/netd_rpc.proto create mode 100644 dstack/vmm/netd-rpc/src/generated/mod.rs create mode 100644 dstack/vmm/netd-rpc/src/lib.rs diff --git a/docs/libvirt-network-filter.md b/docs/libvirt-network-filter.md index 5bdfb7ccc..1e161c183 100644 --- a/docs/libvirt-network-filter.md +++ b/docs/libvirt-network-filter.md @@ -70,11 +70,16 @@ run directory. ## Architecture -`netd` is a host-level privilege broker.
