Clear the session when access-token revocation fails.
When OAuthAccessTokens().Delete returns an error, logout returns before refresh-token cleanup and o.sessions.DeleteSession. The refresh-token cookie and server-side session can then reach refreshSession. Run cleanup on this failure path and preserve the revocation error separately.

@TheRealJon, yes. I reviewed the implementation, the session-store behavior, and the existing tests.
Both findings identify valid defects:
-
If
OAuthAccessTokens().Deletefails,logoutreturns before it callsDeleteSessionandClearRecoveryCookie. The encrypted refresh-token cookie remains available.getLoginStatecan use it to refresh or restore the session. -
If
OAuthAuthorizeTokens().Deletefails, the remote refresh token can remain valid. The current handler logs the error and returns204.
The first finding needs one correction. On a refresh-token revocation failure, the handler must not return before local cleanup. It must expire the local session, refresh-token cookie, and recovery cookie first. It should then return an error response to report that remote revocation failed.
The robust flow is:
- Attempt both remote revocations.
- Record any revocation error.
- Always clear local session state and cookies.
- Return
204only if both remote revocations succeed. - Return
500after local cleanup if either remote revocation fails.
There is no existing OpenShift logout test. pkg/auth/oauth2/auth_test.go only covers authenticator construction. The change should add failure-path tests that assert both the error response and local cookie/session cleanup.

For github.com/gorilla/sessions v1.4.0, what does CookieStore.Get return when a cookie cannot be decoded or verified?
💡 Result:
For gorilla/sessions v1.4.0, when a cookie cannot be decoded or verified, CookieStore.Get returns a new session object along with a non-nil error [1][2]. Specifically: - The session object returned is a fresh session (i.e., its IsNew field will be true) [1][2]. - The error returned indicates the reason the existing cookie could not be successfully decoded or verified (such as a signature mismatch or expired/invalid data) [3][4]. Because Get always returns a session, even if it cannot decode the provided cookie, it is common practice in many applications to ignore the error returned by Get if you simply intend to proceed with a blank or new session when the existing one is invalid [5][6]. Calling session.Save on this returned session will effectively overwrite the invalid cookie with a new, valid one in the user's browser [6].

github.com/gorilla/sessions v1.4.0 CookieStore.Get source store.go securecookie.Decode error behavior
💡 Result:
In github.com/gorilla/sessions v1.4.0, the CookieStore.Get method behaves as a convenience wrapper around Registry.Get [1], which in turn calls CookieStore.New if a session does not already exist in the registry [1][2]. When CookieStore.New encounters an issue decoding an existing cookie (e.g., due to invalid keys, tampered data, or expired timestamps handled by the securecookie package), it returns a new, empty session along with the error [1]. Key aspects of this behavior include: 1. Always Returns a Session: CookieStore.Get (via New) is designed to always return a *Session object, even if an error occurs during the decoding process [1][3]. This ensures that application logic can proceed with a fresh session if the previous one is unreadable [4]. 2. Error Indication: The error returned indicates that while a cookie was present, it could not be successfully decoded using the configured codecs [1]. 3. Recommended Handling: The official gorilla/sessions documentation and community guidance suggest that while the error can be checked, Get() often returns a valid (though empty or new) session object regardless of the error [3][5]. Developers often choose to ignore the error returned by Get() if they intend to treat a failed decryption as a session reset (i.e., treating the user as unauthenticated) [5]. 4. Underlying Mechanism: The securecookie.Decode method (called within CookieStore.New) performs several validation steps, including checking the length, verifying the MAC (message authentication code), validating timestamps (if configured), and decrypting the payload [6]. Any failure in these steps results in an error [6], which CookieStore bubbles up [1]. Common scenarios where securecookie.Decode returns an error include key rotation mismatches, modified or malformed cookie values, and expired sessions [4][6][7]. Since CookieStore continues by returning a new *Session with IsNew set to true, the application effectively invalidates the unreadable session and starts a new one [1].

Review findings
Reviewed the full change (key rotation via previousCookie* keys, refresh-token-in-cookie storage, and the new recovery cookie for pod-restart persistence). The key-rotation plumbing, legacy-format fallbacks, and test updates look correct and consistent. Two things worth addressing before merge:
🔴 Blocking: logout never clears cookies (see inline comment)
The cleanup runs in a defer, so DeleteSession/ClearRecoveryCookie add their Set-Cookie headers after w.WriteHeader(...) has already committed the response on every path. net/http drops those headers — exactly the failure mode the code comment warns about. The browser keeps both openshift-refresh-token and the new openshift-recovery-token cookies after logout. The recovery cookie is the concern: it holds the access token and getLoginState → recoverSession will try to rebuild the session from it on the next request. Fix: call DeleteSession/ClearRecoveryCookie up front, before any WriteHeader. This path currently has no unit-test coverage (only DeleteSession is tested directly), which is why CI stayed green — worth adding a test asserting MaxAge=-1 for both cookies after logout.
🟡 Security posture change (design note)
Full refresh + access tokens now live in client cookies (previously only opaque server-side reference IDs). This is inherent to surviving pod restarts and is mitigated by gorilla AES encryption + HMAC and HttpOnly/Secure/SameSite=Strict, but it's a deliberate tradeoff — please make sure the PR description calls it out for reviewers.
Minor
byRefreshTokenID is now read-only (kept for backward-compat with pre-upgrade cookies). After a pod restart the map is empty, so a legacy cookie won't resolve via ID — the recovery cookie is what covers those users during rollover. Acceptable, just noting.

🔴 This defer defeats its own comment. It runs after the function body returns, i.e. after every w.WriteHeader(http.StatusNoContent) on the paths below (lines 204, 211, 227, 241). Once WriteHeader is called, net/http ignores any further Set-Cookie headers, so DeleteSession (cookie expiry) and ClearRecoveryCookie are silently dropped and the browser keeps the refresh-token and recovery cookies after logout.
DeleteSession/ClearRecoveryCookie only add headers (they never write the status), so call them up front instead of deferring:
func (o *openShiftAuth) logout(w http.ResponseWriter, r *http.Request) {
ctx := r.Context()
// Clear local state first, before any WriteHeader commits the response.
o.sessions.DeleteSession(w, r)
o.sessions.ClearRecoveryCookie(w, r)
...Suggest also adding a unit test for logout asserting Set-Cookie MaxAge=-1 for both cookies — this handler currently has no direct coverage.
Console sessions were tied to console pods — when pods restarted, all user sessions were terminated and users had to re-login. This change introduces session persistence via encrypted browser cookies. For OpenShift OAuth: a recovery cookie stores the encrypted access token. After pod restart, the new pod decrypts it and rebuilds the session. For OIDC: the existing refresh token cookie enables recovery. After pod restart, the new pod reads the refresh token from the cookie, exchanges it with the IdP for fresh tokens, and rebuilds the session. Large refresh tokens (>4KB) fall back to a server-side reference ID to avoid exceeding browser cookie size limits. Session cookies are per-pod (appended with POD_NAME) to handle multi-pod deployments. Previous encryption keys are supported for graceful key rotation during rolling updates. The logout handler clears session and recovery cookies before writing the HTTP response to ensure Set-Cookie headers are not silently dropped by Go's ResponseWriter.

Do not silently drop configured previous keys.
If either configured previous key cannot be read, Complete returns success with an incomplete key pair. The downstream authenticator then omits both previous codecs. Existing cookies encrypted with the prior keys become unreadable during rotation.
Validate that both previous paths are set together. Return an error when either explicitly configured file cannot be read.
As per coding guidelines, **/*.go: “Never ignore error returns”.

Synchronize all byRefreshTokenID access.
Line 123 writes byRefreshTokenID without SessionStore.mux. GetCookieRefreshToken reads the same map without sessionLock. A request with a reference-ID cookie can race with an oversized-token login or refresh. Go can terminate the process with a concurrent map read/write failure.
Add SessionStore methods that lock around all reference-ID lookup, insertion, and deletion.

Use size-aware refresh-cookie storage.
UpdateCookieRefreshToken bypasses setRefreshTokenCookie. If the refreshed token exceeds maxCookieSize, this path writes a cookie that browsers can reject. The user then loses the refresh token after a concurrent refresh short-circuit.
Call setRefreshTokenCookie before saving the cookie.

Analysis / Root cause:
Console sessions are stored entirely in per-pod process memory. When a pod restarts (upgrades, scaling, OOM, operator reconciliation), all sessions are lost and users must re-authenticate. This affects all users but is most disruptive for clusters using external IdPs (htpasswd, LDAP) where re-authentication requires full credential entry.
Two architectural limitations cause this:
