fix: review recommendations for PR #720 #754

Mossaka · 2026-02-12T19:55:54Z

Summary

Implements review recommendations from the PR #720 code review:

Remove legacy one-shot-token.c: The Rust port (src/lib.rs) is complete and the C file was only kept "for reference". Removes the file and updates README.md to reflect the current file list.
Add -v to fallback docker rm -f: The stopContainers fallback path (when docker-compose.yml is missing) used docker rm -f without -v, which could leave orphaned volumes. Now matches the behavior of docker compose down -v in the normal path.
Fix pre-existing test failures: Updates test expectations to match the PR's stdio: ['ignore', 'ignore', 'inherit'] pattern, creates docker-compose.yml in stopContainers test so the compose-down path is properly exercised, and adds a new test for the fallback (missing compose file) path.

Test plan

All 747 unit tests pass (npm test)
ESLint passes with 0 errors (263 pre-existing warnings)
TypeScript build succeeds (npm run build)
CI passes

- Remove one-shot-token.c (legacy C impl kept "for reference" after Rust port). The Rust implementation in src/lib.rs is the sole implementation. - Add -v flag to fallback `docker rm -f` in stopContainers to clean orphaned volumes, matching the `docker compose down -v` normal path. - Fix pre-existing test failures: update stdio expectations to match the PR's ['ignore', 'ignore', 'inherit'] pattern, create docker-compose.yml in stopContainers test so the normal path is exercised, and add a new test for the fallback (missing compose file) path.

      );


The new test for the fallback path doesn't actually verify that the -v flag is included in the docker rm -f -v command. The test currently mocks docker ps to return empty stdout (no containers found), which means the docker rm command is never called. To properly test the fix from this PR, the test should mock docker ps to return a container ID so that the docker rm -f -v command is executed and can be verified.

Suggested change

// Mock docker ps returning empty (no containers found)

mockExecaFn.mockResolvedValueOnce({ stdout: '', stderr: '', exitCode: 0 } as any);

mockExecaFn.mockResolvedValueOnce({ stdout: '', stderr: '', exitCode: 0 } as any);

await stopContainers(testDir, false);

expect(mockExecaFn).toHaveBeenCalledWith(

'docker',

['ps', '-aq', '-f', 'name=^awf-agent$'],

);

// Mock docker ps returning a container ID so docker rm is executed

mockExecaFn.mockResolvedValueOnce({ stdout: '12345\n', stderr: '', exitCode: 0 } as any);

// Mock docker rm -f -v succeeding

mockExecaFn.mockResolvedValueOnce({ stdout: '', stderr: '', exitCode: 0 } as any);

Chroot Version Comparison Test Results

The chroot mode was tested to verify that host package manager binaries are accessible from within the container.

Runtime	Host Version	Chroot Version	Match?
Python	3.12.12	3.12.3	❌ NO
Node.js	v24.13.0	v20.20.0	❌ NO
Go	go1.22.12	go1.22.12	✅ YES

Overall Status: ❌ FAILED - Not all versions match

Analysis

Python: Minor version mismatch (3.12.12 vs 3.12.3)
Node.js: Major version mismatch (v24 vs v20) - container is using older Node.js
Go: ✅ Versions match perfectly

The test validates that AWF's chroot mode can transparently access host binaries. Version mismatches indicate the container may not be properly accessing the host installation.

Review Results

Two independent review agents analyzed PR #720 (which this PR targets). Here are the findings:

Functional Comparison: C vs Rust

All critical functionality is preserved. The Rust port is a faithful translation with improvements:

Aspect	Verdict
Default token list (11 tokens)	Identical
Custom tokens (`AWF_ONE_SHOT_TOKENS`)	Identical parsing, edge cases
`getenv` interception	Same cache-and-unset semantics
`secure_getenv` interception	Same fallback behavior
Thread safety	Improved (Mutex with poisoning recovery)
Memory management	Same intentional never-free pattern
Logging format	Same `[one-shot-token]` prefix, all to stderr

Improvements in Rust version:

Code deduplication via shared handle_getenv_impl()
Fixed thread safety inconsistency (C checked token sensitivity outside mutex in secure_getenv)
Explicit malloc failure check for token allocation
New check_task_environ_exposure() verification feature
Included unit tests

No functional regressions identified.

Security Stance Review

Overall: The PR reduces attack surface.

Finding	Severity	Notes
`/proc/self/environ` kernel exposure	High (pre-existing)	`unsetenv()` doesn't modify kernel's `mm->env_start`; documented limitation
`~/.cargo` hidden in non-full-access	Medium	tmpfs hides `~/.cargo/bin` too; may break Rust workflows
`check_task_environ_exposure` naming	Medium	Checks userspace `environ` pointer, not `/proc` files
curl-to-shell Rust install in Dockerfile	Medium	Standard practice but no hash verification
`Cargo.lock` not committed	Medium	Non-deterministic dependency resolution
tmpfs credential hiding	Info (positive)	Net improvement over `/dev/null` approach
Selective home mounting	Info (positive)	`$HOME` no longer fully exposed
docker-compose.yml deletion	Info (positive)	Correctly implemented, race window negligible
`docker rm -f -v` fallback	Info (positive)	Matches `docker compose down -v` behavior
All `unsafe` code in Rust	Low	Necessary and correctly scoped for LD_PRELOAD

CI Status

All checks pass except "Smoke Claude" which timed out (10-minute limit for Claude API e2e test). This is a known flaky test unrelated to these changes — the one-shot-token library initialized and cached tokens correctly.
