test(openbao): exercise the health judge against native servers - #4989
Conversation
Start three disposable servers of the pinned OpenBao release from the declared Raft configuration, capture their real health responses in the judge's documented format, and require the expected verdict in each replacement state. Cold start, bootstrap and a sealed restart pass; the leader-change state does not settle yet and is still being worked on. Part of #4969 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

- Around line 348-355: Update cluster.step to defer checking c.t.Failed() and
calling c.dumpLogs(), so the log dump runs when run() exits through
testing.T.Fatal or testing.T.Fatalf.
- Around line 160-163: Update the “one server unreachable” step in the test to
wait until both openbao-0 and openbao-1 return complete, HTTP 200 health
responses showing initialized and unsealed state, with exactly one server
active, before calling c.expect. Do not rely on Raft membership as a substitute
for validating both health responses.

[warning] 288-288: A log/format call (log.Print/Printf/Println, the Fatal/Panic variants, fmt.Sprintf, or a structured logger's Info/Warn/Error/Debug method) is given a message built by concatenating a string literal with a non-literal value such as request data. Unsanitized, attacker-controlled input written to logs enables log forging / CRLF injection: an attacker can inject newlines to spoof log entries or break log parsers. Do not concatenate raw input into the log message; pass it as a separate structured field/argument (e.g. 'log.Printf("user: %s", user)' or 'logger.Info("login", "user", user)') and strip or escape newline characters first.

If that input is attacker-controlled (and especially when the command is a shell such as sh -c/bash -c), this enables OS command injection. Pass untrusted data as separate, fixed arguments instead of interpolating it into a command string, avoid invoking a shell, and validate/escape the input where a shell is unavoidable.

143-158: 🎯 Functional CorrectnessThe step-down path transfers Raft leadership.
In OpenBao v2.6.3,
sys/step-downreleasesc.heldHALock, and the Raft lock implementation performsl.b.raft.LeadershipTransfer(). The concern that it only releases the HA lock is therefore not applicable. The proposed stop-and-restart workaround is not supported by this implementation.

Every server declared its own audit file path, which the shared Raft log rejects on followers, so no follower could become active. Declare the identical path production uses, wait for every server to vote before the step-down, and run the native regression in the standby canary.

Lane state when this was written: CodeRabbit declined the full review requested at this head at 17:54Z as rate-limited (next included review in about 50 minutes); Codex and Cursor Bugbot have been out of usage since about 09:55Z. Reviewed at head cf68247c5092a9d1c3953b620559a7273333db48. CodeRabbit's full review of the previous head 3f74d487 was green, so this review covers the new commit in full and re-reads the regression as a whole.
What changed since 3f74d487:
- Each server now declares the same relative audit-file path instead of its own absolute one.
- The leader-change state waits until every server is a Raft voter before it steps down the active server.
- The regression runs in the standby canary with the pinned, checksum-verified server binary, and the canary's path filter now includes the regression, the judge and
internal/strictjson. - The judge README says how the native regression is supplied.
Checks I made:
- Root cause, confirmed in the server logs. The file audit device is stored in the shared Raft log. A follower whose own config named a different
file_pathfailed post-unseal setup ("modifications to audit devices are not allowed"), so no follower could become active and the leader change hung. Production pods all declare/openbao/audit/audit.log. One identical relative path is therefore the faithful substitution, and it still resolves inside each server's own directory, because each server's working directory is its own root. - Both changes are needed. With only the audit fix reverted, the step still times out (126 s). With only the voter wait missing, the logs show the joined servers as Raft non-voters, so no other server can win an election.
waitVotersreads the configuration through the active server with the synthetic token. It requires exactly the named servers, every one a voter, and no unknown peer; anything short of that keeps waiting until the 90 s bound.- Locally (darwin/arm64, pinned 2.6.3): the regression passed in both runs (43 s alone, 40 s inside the canary), the full
test-openbao-standby-canary.shpassed end to end, andgo vet,golangci-lintandshellcheckare clean. - Scope stays as stated: synthetic store and credentials, loopback only, nothing returned by a server is logged.
Findings: none.
Verdict: GREEN at cf68247

Why
The OpenBao health check that must gate each server replacement has only been tested against made-up responses. Nothing yet shows that real servers report what it expects in the states a replacement meets, so it cannot be trusted to hold a replacement while the secrets service is down.
What
A regression starts three throwaway servers of the release production runs, on the local machine with synthetic data, and walks them through cold start, first-time setup, a sealed restart, a leader change, an unreachable server, a server rejoining with empty storage and an uninitialized server. In each state it records the real health answers and requires the check's expected verdict. It runs in the existing OpenBao pull-request check whenever the secrets service, the health check or the regression changes.
