test(proxies): stop the live test from removing containers it did not create - #16
Review mirror of GeiserX#263 (CodeRabbit is rate-limited there). Findings are fixed on the real PR; this one is closed after.
Summary by CodeRabbit
Tests
Live-test cleanup now verifies that fixed-name containers carry the test’s ownership label before proceeding. Containers without the label are left untouched, and inspection or decoding errors stop the test.
The test-created SOCKS proxy is marked as test-owned so it can be distinguished from unrelated containers.
Added coverage confirming that unowned containers are rejected and test-owned containers are accepted.
…create
The live proxied-copy test ran docker rm -f -v on three fixed names before it
started, so a container of the operator's under one of those names lost its
anonymous volumes. It now inspects each name first and stops when one is held
by a container without the labels this test puts on its own.
The live proxy test checks ownership labels on fixed-name containers before cleanup. It allows missing containers, reports inspection failures and foreign containers, and labels its gost container. A unit test covers owned and foreign container labels.
Changes: Live-test container ownership
Layer / File(s)
Summary
Ownership check and cleanup guard internal/runtime/proxied_live_test.go, internal/runtime/proxied_test.go
The live proxy test checks container labels before cleanup and labels its gost container. The added unit test checks that foreign containers are refused and owned containers are accepted.
This only affects a live Docker test. A narrow race or an unusual inspect response could still let the test remove a container it did not create. The risk is small and bounded, so it can be accepted or fixed as a follow-up.
Security architecture risk: Low · up to 0eef8
The change reduces accidental deletion in an opt-in Docker test without changing production behavior. Cleanup still relies on fixed names after a one-time ownership check, a pre-existing limitation whose safety under concurrent execution is not established.
Retained concerns
No architecture-level concerns identified.
Security review details
Security Blast Radius
inferred — The changed destructive path targets three fixed container names on the Docker daemon available to the test process, using forced removal with volume removal enabled. Execution requires explicit live-test opt-in and existing Docker access; the PR does not add a remote source of cleanup authority.
Trust Boundaries and Controls
observed — The new control uses managed/service/proxy labels for the earner and tunnel and a live-test slug label for gost. These identify logical ownership, not a unique invocation. The mocked-label test demonstrates rejection of an unrelated gost container and acceptance after its ownership label matches.
Resilience and Maintainability Implications
inferred — A container replacement after preflight, or another invocation using the same names and labels, can still be targeted by subsequent name-based cleanup. This lifecycle limitation predates the PR's unconditional cleanup and is not established as introduced or worsened here. The available evidence does not establish external serialization.

- Around line 57-60: Update the error handling in the `dk` inspection flow to
treat a container as absent only when the complete error identifies the
requested container by name; do not use a broad substring match such as “no
such.” Preserve the existing handling for all other inspection errors.

Remove containers by inspected or created ID, not by name.
The newly accepted missing-object response allows this test to proceed when a name is absent. If another process creates a container with that name before docker run, the run fails, but t.Cleanup still removes that container and its anonymous volumes. Record container IDs and remove only the IDs inspected or created by this test.

Update the cleanup closure in the test to remove containers by IDs recorded when
this test inspects or successfully creates them, not by the earner, tunnel, or
gost names. Ensure a failed docker run cannot make cleanup remove an unrelated
container created with the same name.
