Bootstrap the native security policy module and versioned bus contracts by senamakel · Pull Request #2 · tinyhumansai/tinysecurity

senamakel · 2026-10-10T15:22:03Z

Replace the greeting template with a real configurable native security module. Hosts compile only tinysecurity-bus; policy decisions run inside the loaded module through Evaluate, batched Check and PolicyInfo. Unknown tool effects deny, and the credential/system/traversal floor remains active when autonomy is disabled.

This delivers the T0/T1 bootstrap for #1 and tinyhumansai/openhuman#7328: four implemented crates, versioned contracts and golden fixtures, SDK init/reinit with policy generations, conservative command/path checks, a real native-loader verifier, three-OS CI, and the existing eleven-platform release packaging. Invalid configuration—including an unsupported requested wire version—cannot replace the active policy. Judge configuration secrets have redacted Debug; unavailable judge configuration is rejected. Future approval/redaction/egress/sandbox/audit/callback contracts are reserved without advertising unimplemented handlers.

Validation: 102 tests; formatting; strict Clippy; all-target build; warning-denied rustdoc; MSRV 1.88; cargo-deny; exact serde/thiserror-only contract dependency check; and >=90% coverage in every executable source file pass. Independent review reran the tests and Linux native verifier. Native smoke also exercises digest/tamper rejection and accepted/rejected reconfiguration. The latest hosted Linux/macOS/Windows native jobs passed. Automated re-review is pending. Released artifacts remain pending. Windows loading uses a restricted ACL copy.

Review fixes require absolute host-resolved operation paths, protect Unix executable/library/device roots and Windows roots on every drive, and clarify the internal trusted-host context and version compatibility directions. New path regressions failed before the fixes and pass afterward; lexical Windows root checks cover A–Z without depending on mounted drives. Independent focused review found no actionable regressions.

Related PRs: tinyhumansai/tinybox#28 and tinyhumansai/openhuman#7331.

Synthetic native latency measurements and reproduction instructions are in docs/performance.md. They do not establish a production migration budget.

This is a bootstrap, not completion of #1: rich shell parity and the approval, redaction, egress, sandbox planning, audit, auto-approve and crypto engines remain outstanding. OpenHuman caller migration must wait for the relevant upstream implementations and published release checksums. No issue is closed by this PR.

Conclusion: Success
Scope reviewed: all assigned evidence
Lane summary: This revision resolves every finding raised earlier: the adapter and error modules exist with library targets, DecideRequest/DecideResponse are defined and wire-pinned, newer minor versions are rejected at init/reinit, the command allowlist is honored when enabled, Windows system floors cover every drive including extended/device/Volume aliases with a test that loops A–Z, symlink and broken-symlink path tests point outside the action root, threshold bounds are enforced, the release workflow invokes verify_module against the published archive, plan/spec docs mark the bootstrap as in-progress, and path-boundary checks go through the public Policy API. Secret Debug output is redacted and tested, with plaintext serialization confined to the documented trusted SDK-config boundary. The remaining trust-boundary items (CallerContext deserialization, host adapter binding) are now explicitly covered by the accepted spec's trust model. The change looks sound to merge as a bootstrap. _The code index for this repository is cold, so this review saw the diff alone._ _Memory was unavailable (model: cortex: v1/recall: error sending request for url (http://cortexdb:3141/v1/recall\)\), so this review ran without it._

📝 Walkthrough

Walkthrough

The pull request replaces the Rust template workspace with TinySecurity. It adds a versioned TinyBus contract, conservative policy checks, and a native module adapter. It also updates cross-platform CI and release workflows, removes template crates and examples, and adds TinySecurity documentation.

Changes

TinySecurity bootstrap

Layer / File(s)	Summary
Versioned TinyBus contract `Cargo.toml`, `crates/template-bus/`, `crates/tinysecurity-bus/`	Adds versioned policy, error, and reserved capability payloads, interface names, fixtures, and wire-compatibility tests. Removes the former template bus contract and updates workspace dependency aliases.
Conservative policy engine `Cargo.toml`, `crates/tinysecurity-policy/*`	Adds command and path checks, ordered policy evaluation, configuration validation, and generation tracking. Tests cover policy denials, path boundaries, command allowlisting, and failed reconfiguration.
Native module and host verifier `crates/template/`, `crates/tinysecurity-module/`, `crates/tinysecurity/*`	Adds the TinyBus policy adapter and a native-module verifier for loading, digest checks, interface calls, reconfiguration, and timing. Removes the template greeting crate and its adapter.
Cross-platform validation and release wiring `.github/ISSUE_TEMPLATE/config.yml`, `.github/workflows/*`, `AGENTS.md`, `README.md`, `MODULE.md`, `ROADMAP.md`, `deny.toml`, `docs/performance.md`	Runs CI across three operating systems, adds platform-specific module verification, limits coverage collection to Linux, and targets the TinySecurity module in release jobs. Updates project guidance, overview documents, and security-report routing.
Architecture and implementation documentation `docs/adr/`, `docs/plans/`, `docs/specs/*`	Adds security-module architecture decisions, a specification, and an implementation plan. Removes the template retry examples and former TinyBus module release plan and specification.

Merge Risk: 🔵 Low · up to e66b8

Correct the Windows path protection and the RPC-name formatting before relying on this bootstrap; the system-drive gap does not currently affect migrated production callers.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to e66b8

The new authorization gate has a Windows system-path protection gap on non-C drives. Read/write restrictions reduce exposure, but host authentication, execution confinement and failure recovery still need end-to-end validation before production migration.

Retained concerns

Low · security · observed: The newly introduced unconditional system-path floor protects Windows system roots only on C:. On native Windows, an accessible equivalent root on another volume can pass lexical and canonical checks and receive Allow when discretionary policy is disabled. Enabled containment narrows exposure but does not correct the floor or prevent such a directory from qualifying as an action root.

Security review details

Security Blast Radius

inferred — The floor gap can affect protected Windows directories on non-C volumes accessible to the executing host process. Disabled-policy reads can pass for any valid caller tier; writes additionally require a non-read tier and non-cron origin. This is policy authorization exposure, not demonstrated OS privilege escalation or cross-tenant compromise. Enabled action-root containment narrows reachable paths.

Security Findings and Attack Paths

inferred — A host-derived path request influenced toward an accessible D:/Windows/System32 path can reach path::check, miss the C:-specific floor in both lexical and resolved forms, and receive Allow with discretionary policy disabled. Canonicalization and root validation reuse the same incomplete floor. The retained finding confirms the control deficiency; concrete production attacker-to-host reachability remains unproven.

Trust Boundaries and Controls

observed — Caller identity, tier, origin and complete operation checks are serialized inputs that the adapter forwards without local sender binding. The documented boundary explicitly requires authenticated host construction and forbids model-provided authority. With no production host adapter available, this is a delegated control whose implementation is unverified, not a confirmed identity-spoofing bypass.
observed — Decisions identify the active generation and are non-cacheable. Documentation delegates stale-generation rejection, safe-open or jail confinement, and trusted executable resolution to the host. Authorization over a path string therefore does not itself guarantee confinement of later execution.

Resilience and Maintainability Implications

observed — Initial setup serves the interface before requesting its name and recording ACTIVE, without a local cleanup path for subsequent failure. The adapter relies on SDK setup serialization and fault latching. The reviewed revision contains the SDK as a gitlink without available implementation source, and documentation identifies fault-injection and timeout latching as outstanding conformance work; interrupted or partial setup recovery remains unverified.

Hardening Proposals

proposed — Make protected Windows root recognition independent of an assumed C: installation, and validate lexical, canonical and configured-root behavior for protected locations on other volumes.
proposed — Before production migration, demonstrate authenticated host-only invocation, stale-result rejection and execution confinement, together with SDK setup serialization, fault latching and cleanup after interrupted registration. Preserve fail-closed behavior rather than adding fallback authorization.

Construct the path check through a public API

This only requires implementing path checks inside the policy engine; it does not require exposing or constructing them through the public API used by callers. The resulting implementation can leave the path check inaccessible to the adapter or host integration while all listed engine tests pass. Specify the public path-check contract and test it through that API.

Keep workspace boundaries active when autonomy is disabled

This exercises only relative paths in the disabled mode, so it does not catch the existing bypass for an absolute path inside workspace_dir: the path checker returns successfully before applying the workspace boundary when enabled is false. Add an absolute workspace-path assertion for both policy modes, or keep the workspace check outside the enabled guard. This earlier concern remains unresolved; it is marked late because the implementation is not changed by this pull request.

Keep workspace boundaries active when policy is disabled

When config.enabled is false, every non-floor absolute path is allowed before checking action_dir, workspace_dir, or forbidden_paths. A caller can therefore access paths outside the configured action scope simply by disabling the discretionary policy, while the surrounding comments and unconditional safety model imply that these filesystem boundaries must remain enforced. Apply the scope checks regardless of config.enabled; only optional policy rules should be bypassed.

Keep workspace boundaries active when autonomy is disabled

The plan asks for characterization of disabled autonomy but does not state that workspace boundaries must remain enforced in that mode. A migration could therefore reproduce a disabled-autonomy path that bypasses workspace checks while still passing the listed characterization categories. Add a test and implementation requirement that the workspace boundary remains active regardless of autonomy state.

Keep workspace boundaries active when policy is disabled

The plan does not explicitly require workspace checks to remain active when policy is disabled. Testing disabled/enabled autonomy is not equivalent to testing the disabled-policy path, so that path can accidentally bypass workspace restrictions during migration. Add an explicit disabled-policy boundary test and implementation requirement.

Bind checks to the trusted host adapter

This requires ABI dispatch and callbacks but does not require policy checks to authenticate the adapter that supplies caller, generation, or authorization context. A caller could therefore invoke the engine through an untrusted or forged host path while the policy sees apparently valid context. Require the policy entry points to accept context only from the attested host adapter and add a test that forged adapter/context claims are rejected.

Reject newer minor contract versions

This only claims that version rules exist; it does not define the compatibility rule that rejects a newer minor contract version. A host accepting a contract it does not understand can misdecode messages or advertise unsupported members. Specify and test the exact major/minor acceptance rule, including rejection of newer minor versions.

Reject thresholds above 1000

The contract work says to reject invalid thresholds, but it does not preserve the required upper bound of 1000 or require a test for values above it. Without that explicit bound, a configuration such as 1001 can be accepted as valid. State the maximum and add the boundary test.

Reject symlinks that resolve outside the workspace

Denying normalization failures is not the same as resolving a symlink and checking its target against the configured workspace. A valid symlink from inside the workspace to an outside path can still escape confinement unless the resolved target is checked. Require the resolved target of every symlink to remain within the applicable workspace boundary.

Reject paths outside the configured action directory

This condition denies paths outside action, but it allows paths inside the configured workspace only to reject them afterward. More importantly, the configured workspace is treated as a denied subtree while action is the only allowed root; if the intended boundary is that operations may use the action directory but never the workspace, this needs to remain enforced in both enabled and disabled modes. Move this scope check before the config.enabled early return and preserve both constraints as unconditional checks.

Deny Windows device-namespace paths

On Windows with policy disabled and a sufficiently privileged Full caller, \\.\PhysicalDrive0 bypasses this normalization because only \\?\ and \??\ are stripped, while windows_system_root does not recognize PhysicalDrive; if the accessible device canonicalizes, check consequently returns Allow. Microsoft documents that this namespace provides direct physical-disk access, bypassing the filesystem (Win32 device namespaces). Reject \\.\, GLOBALROOT, and other raw-device namespaces before resolution so unimplemented device effects fail closed.

Give the policy crate its own error type

The wildcard re-export makes tinysecurity_bus::Error and its Result alias the policy crate's only error API, so public methods such as Policy::new expose the wire-contract error taxonomy and this crate has no required src/error/mod.rs. Define a policy-local Error/Result and map those failures to contract or bus errors in the adapter rather than coupling the engine directly to future transport-facing variants.

Add the required crate-root examples

This new crate root contains only a two-line description and therefore omits the required primary-entry-point overview, runnable example, and explanation of what the crate deliberately excludes; the same omission appears in the other three newly introduced crate roots. Expand each src/lib.rs with the mandated crate-level documentation so consumers can compile the examples and understand the architectural boundary.
