Summary

  • A planned Docker spawn with a CPU or memory bound is refused at plan mapping (CpuLimitUnenforceable / NativeResourceLimitsUnenforceable), even though Docker enforces both bounds. This is TS-E2E finding TS-E2E-002.
  • validate_resources now accepts cpu_millicores and memory_bytes when the executor is Docker. Every other limit stays refused, with an error that names the real reason.

Problem

  • sandbox/plan.rs#validate_resources refused any cpu_millicores for every executor, and any memory_bytes for everything but Docker-with-pids.
  • For Docker both bounds are enforced: PlannedSpawn::apply writes them into the Docker overrides, and TinyBox's RunDocker passes them as --cpus and -m.
  • So every bounded container plan failed instead of running bounded. The checks also ran in an order where a zero limit could be reported as "unenforceable" rather than as ZeroLimit.

Solution

validate_resources now checks in this order:

  1. A zero cpu/memory/pids limit → ZeroLimit, for every executor.
  2. cpu_time_ms → CpuTimeUnenforceable. disk_bytes → DiskLimitUnenforceable. Both are unchanged.
  3. Docker: pids_max → PidsLimitUnenforceable, because RunDocker has no PID limit. Otherwise CPU and memory are accepted.
  4. Host with any cpu/memory/pids bound → HostResourceLimitUnenforceable.
  5. Native (jail): cpu_millicores → CpuLimitUnenforceable; memory or pids → NativeResourceLimitsUnenforceable.

Nothing that was refused for Host or the jail is now accepted.

Tests

  • sandbox/plan_tests.rs:
    • docker_cpu_and_memory_bounds_are_accepted: CPU and memory together, memory only, and CPU only.
    • native_cpu_bounds_are_refused_instead_of_being_ignored
    • a_zero_docker_bound_is_refused
    • These replace unsupported_planned_bounds_are_refused_instead_of_being_ignored, which asserted the old Docker refusal.
  • Red control: commit 2208276aad (main plus the tests only) runs sandbox::plan::tests with 17 passed and 2 failed: docker_cpu_and_memory_bounds_are_accepted and a_zero_docker_bound_is_refused.
  • The end-to-end rows (SB-18/SB-19: a bounded Docker spawn runs) are not run here, because the cuttlefish runner has no Docker.

Submission Checklist

  • Tests added: three unit tests (above), with a red control on main.
  • N/A: diff coverage is measured by the PR's CI lane; every branch of the changed function is exercised by the plan tests.
  • N/A: no feature row added, removed or renamed in docs/TEST-COVERAGE-MATRIX.md.
  • N/A: no matrix feature IDs affected.
  • No new external network dependencies introduced.
  • N/A: no release-cut surface changes (docs/RELEASE-MANUAL-SMOKE.md).
  • N/A: no GitHub issue tracks this. It is TinySecurity E2E review finding TS-E2E-002.

Impact

  • Runtime: sandboxed Docker runs with CPU or memory bounds now start, bounded, instead of being refused.
  • Security: no limit that was refused for Host or the jail is accepted now. Docker PID limits are still refused because they would be ignored.

Summary by CodeRabbit

  • Bug Fixes
    • Docker sandbox plans now accept CPU and memory limits, including when both are set together.
    • Resource limits set to zero are rejected. Fractional CPU limits are rounded down to millicores, so values below one millicore are rejected rather than rounded up.
    • Host sandbox plans continue to reject CPU, memory, and process limits. CPU-time and disk limits remain unsupported, and executor-specific restrictions on other resource limits remain in effect.

A Docker plan with the shipped [runtime.docker] bounds, a memory bound
alone, or a CPU bound alone must map to a BoxPlan; a zero bound is still
refused and a native CPU bound still is. On main every bounded Docker plan
is refused (TS-E2E-002).
validate_resources refused any CPU bound for every executor and a memory
bound for Docker, so every planned Docker spawn carrying the
[runtime.docker] defaults (1.0 CPU, 512 MB) was refused: local
backend = "docker" and SaaS host_shell never ran a planned command. The
container enforces both: PlannedSpawn::apply writes them into the Docker
overrides and TinyBox's RunDocker passes them as --cpus and -m.

Docker now accepts CPU and memory bounds. It still refuses a PID limit
(RunDocker has none), and every bound stays refused for the host and the
native jail. A zero bound is checked first, for every executor.

Fixes TS-E2E-002.

Walkthrough

Docker CPU limits now round down when converted to millicores. Resource validation rejects zero CPU, memory, and PID limits, and applies executor-specific rules for these limits.

Changes: Sandbox resource limits

Layer / File(s) Summary
Docker CPU limit conversion
crates/openhuman-core/src/sandbox/spawn_plan/mod.rs, crates/openhuman-core/src/sandbox/spawn_plan/mod_tests.rs
Docker CPU limits now round down when converted to millicores. Tests cover fractional values and values below one millicore.
Executor-specific resource validation
crates/openhuman-core/src/sandbox/plan.rs, crates/openhuman-core/src/sandbox/plan_tests.rs
Validation checks zero limits first. Docker plans accept CPU and memory limits when no PID limit is set. Host plans reject CPU, memory, or PID limits. Tests cover Docker acceptance, Jail CPU rejection, and zero CPU rejection.

Full summary

Pull request purpose (title): fix(sandbox): accept CPU and memory bounds for planned Docker spawns. `validate_resources` in `crates/openhuman-core/src/sandbox/plan.rs#fn validate_resources(` is reordered so zero bounds are caught first, Docker accepts CPU and memory (still refusing pids), Host keeps refusing every bound, and native executors keep their refusals. The latest revision also flips the CPU-millicore conversion in `crates/openhuman-core/src/sandbox/spawn_plan/mod.rs#fn limits(policy: &SandboxPolicy) -> ResourceLimits2 {` from ceiling to floor, so a fractional CPU ceiling can no longer be rounded up past what the operator allowed; sub-millicore values become 0 and are refused by the plan-side `ZeroLimit` check. Tests in `crates/openhuman-core/src/sandbox/plan_tests.rs` and `crates/openhuman-core/src/sandbox/spawn_plan/mod_tests.rs` are updated to pin the new branches and rounding.

What changed

For `PlannedExecutor::Docker`, a `pids_max` bound still returns `PidsLimitUnenforceable` while CPU and memory bounds are accepted, on the basis that `PlannedSpawn::apply` writes them into Docker overrides. Host with any cpu/memory/pids bound returns `HostResourceLimitUnenforceable`, native CPU returns `CpuLimitUnenforceable`, and native memory/pids return `NativeResourceLimitsUnenforceable`. In `spawn_plan/mod.rs`, `limits()` now floors fractional CPU cores to millicores instead of rounding up, so a CPU bound is never widened; values below one millicore yield 0 and are refused by the plan. Tests are replaced and extended: the old Docker-refusal test is gone, and new tests cover Docker CPU+memory, memory-only and CPU-only acceptance, native CPU refusal, zero Docker bound refusal, and the new rounding (0.1004 → 100, 0.0004 → 0).

Features

  • Modified — Docker plans may carry CPU and memory bounds: Bounded sandboxed Docker spawns can now be planned and run bounded instead of being refused at mapping time; Docker PID limits remain refused. (crates/openhuman-core/src/sandbox/plan.rs fn validate_resources()
  • Modified — Zero cpu/memory/pids limits are reported as ZeroLimit before executor-specific checks: A zero bound now yields `ZeroLimit` for every executor rather than being reported as unenforceable. (crates/openhuman-core/src/sandbox/plan.rs fn validate_resources()
  • Modified — Host and native executor refusals preserved: Host still refuses every cpu/memory/pids bound and native executors still refuse cpu/memory/pids, so no previously refused Host or jail limit is now accepted. (crates/openhuman-core/src/sandbox/plan.rs fn validate_resources()
  • Modified — Fractional CPU bounds floor to millicores instead of rounding up: A fractional CPU ceiling can no longer be rounded up past the operator's configured bound; sub-millicore values become 0 and are refused by the plan rather than widened. (crates/openhuman-core/src/sandbox/spawn_plan/mod.rs fn limits(policy: &SandboxPolicy) -> ResourceLimits2 {)

Agent review details

critique

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: The change flips the CPU-bound rounding from `ceil` to `floor`, and the diff's claims hold up against the code that consumes the value: `plan::validate_resources` rejects `cpu_millicores == Some(0)` with `ZeroLimit` before any executor branch, so a sub-millicore limit becomes a refusal rather than a widened bound, exactly as the comment and the new `Some(0)` assertion in `bounds_come_from_the_docker_overrides_and_never_loosen` state. Common values are unaffected in the safe direction (1.5 cores still yields 1500 millicores, since `floor(1.5 * 1000.0)` is exact), and `Plan::apply` writes back `millis / 1000.0`, so a floored bound can only be tighter than the operator's configured ceiling. I could not inspect the tinysecurity module (vendor directory not checked out) to see whether it also rejects a `Some(0)` limit before returning an artifact, but on either path the plan cannot be built, so there is no reachable case where the floored value widens the bound. _The code index is behind this pull request (indexed at `678afe773fec`), so retrieved context may be out of date._

security

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Positive: Security lane answered with no reportable defect: flooring is the safe direction for a ceiling bound, the sub-millicore case yields `Some(0)` which `validate_resources` refuses with `ZeroLimit` rather than silently widening, and no untrusted input path, new sink, or repository rule is touched.
  • Lane summary: The change flips the CPU-millicore conversion from ceiling to floor, which is the safe direction for a ceiling bound: a fractional CPU request can no longer be rounded up past what the operator allowed. The sub-millicore case now yields `Some(0)`, and `validate_resources` in `crates/openhuman-core/src/sandbox/plan.rs` rejects a zero bound with `ZeroLimit`, so the plan is refused rather than silently widened, exactly as the new comment and test state. The updated tests match the new arithmetic (`0.1004` → `100`, `0.0004` → `0`), and no untrusted input path, new sink, or repository rule is touched. Nothing to report. _The code index is behind this pull request (indexed at `678afe773fec`), so retrieved context may be out of date._

tests

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Lane summary: This revision flips the Docker CPU-bound conversion from ceil to floor and moves the zero-limit refusal ahead of the executor-specific checks, with tests pinning the new rounding (0.1004 → 100) and the zero case (0.0004 → 0). The rounding contract is covered on both sides — the spawn plan produces 0 below one millicore and `validate_resources` refuses it with `ZeroLimit` — so the change is behaviourally tested and looks safe to merge. _The code index is behind this pull request (indexed at `678afe773fec`), so retrieved context may be out of date._

description

  • Conclusion: Success
  • Scope reviewed: all assigned evidence
  • Positive: Description lane answered finding no description defect: the new commits change `limits()` to floor fractional CPU cores, the arithmetic is consistent with the plan-side `ZeroLimit` check, and the description never states a rounding direction so it remains accurate.
  • Lane summary: The new commits change `limits()` to floor fractional CPU cores instead of rounding up, with the comment and tests updated to match. The arithmetic is consistent with the plan-side `ZeroLimit` check, and the PR description was already written against the ceiling semantics; the description still accurately describes the diff (it never states the rounding direction). No defects found in this increment. _The code index is behind this pull request (indexed at `678afe773fec`), so retrieved context may be out of date._

Reject Docker memory bounds that cannot be represented exactly.

BoxPlan::from_artifact accepts a bound of 512 MiB plus one byte. PlannedSpawn::apply would round that bound up to 513 MiB. Reject non-MiB-aligned bounds so the adapter does not accept a plan that the Docker handoff would widen.

coderabbitai Bot previously approved these changes Nov 6, 2026
A CPU bound is a ceiling: 0.1004 cores must plan as 100 millicores, not 101 (which PlannedSpawn::apply writes back as 0.101), and a bound below one millicore plans as 0, which the plan refuses.
limits() rounded cpu_limit up to the next millicore on the belief that this tightened the bound. For a CPU ceiling it widens it, and since tinyhumansai#8571 accepts Docker CPU bounds the widened value would run. Rounding down never exceeds the operator's ceiling; below one millicore the bound is 0 and the plan refuses it (ZeroLimit).

Reject Docker CPU bounds below 10 millicores.

With CFS quota enforcement, a 1–9 millicore bound passes validation but produces a quota below Linux’s minimum. Docker cannot start the container. Reject these bounds rather than rounding them up, which would widen the requested ceiling.

Test the sub-millicore planning refusal.

The conversion and artifact tests do not exercise the handoff to spawn_plan::plan. A regression that drops the zero from the planner request could pass both tests. Add a planning test that asserts a denial for 0.0004 CPUs, with an accepted-bound control. Do not require ZeroLimit: TinySecurity can return InvalidRequest.
