The existing test (`page.spec.ts`) performs a basic upload/download round-trip. This plan extends coverage to: + +- **Upload flow**: File selection (picker + drag-drop), validation, progress, cancellation, link sharing, error handling +- **Download flow**: Invalid link handling, download button, progress, file save, error states +- **Edge cases**: Boundary file sizes, special characters, network failures, multi-chunk files with redirect, UI information display + +**Key constraints**: +- Tests run against a local XFTP server (started via `globalSetup.ts`) +- Server port is dynamic (read from `/tmp/xftp-test-server.port`) +- Browser uses `--ignore-certificate-errors` for self-signed certs +- OPFS and Web Workers are required (Chromium supports both) + +**Test file location**: `/code/simplexmq/xftp-web/test/page.spec.ts` + +**Architecture**: Tests use the Page Object Model pattern to encapsulate UI interactions, making tests read as domain-specific scenarios rather than raw Playwright API calls. + +--- + +## 2.

Problem Statement + +Browser HTTP/2 connection pooling reuses TLS connections across page navigations (same origin = same connection pool). The XFTP server maintains per-TLS-connection session state in `TMap SessionId Handshake` keyed by `tlsUniq tls`. When a browser navigates from the upload page to the download page (or reloads), the new page sends a fresh ClientHello on the reused HTTP/2 connection. The server is already in `HandshakeAccepted` state for that connection, so it routes the request to `processRequest`, which expects a 16384-byte command block but receives a 34-byte ClientHello → `ERR BLOCK`. + +**Root cause**: The server cannot distinguish a ClientHello from a command on an already-handshaked connection because both arrive on the same HTTP/2 connection (same `tlsUniq`), and there is no content-level discriminator (ClientHello is unpadded, but the server never gets to parse it — the size check in `processRequest` rejects it first). + +**Browser limitation**: `fetch()` provides zero control over HTTP/2 connection pooling. There is no browser API to force a new connection or detect connection reuse before a request is sent. + +## 2. Solution Summary + +Add an HTTP header `xftp-web-hello` to web ClientHello requests. When the server sees this header on an already-handshaked connection (`HandshakeAccepted` state), it re-runs `processHello` **reusing the existing session keys** (same X25519 key pair from the original handshake). The client then completes the normal handshake flow (sends ClientHandshake, receives ack) and proceeds with commands. + +Key properties: +- Server reuses existing `serverPrivKey` — no new key material generated on re-handshake, so `thAuth` remains consistent with any in-flight commands on concurrent HTTP/2 streams. +- Header is only checked when `sniUsed` is true (web/browser connections). Native XFTP clients are unaffected. +- CORS preflight already allows all headers (`Access-Control-Allow-Headers: *`). +- Web clients always send this header on ClientHello — it's harmless on first connection (`Nothing` state) and enables re-handshake on reused connections (`HandshakeAccepted` state). + +## 3. Detailed Technical Design + +### 3.1 Server change: parameterize `processHello` (`src/Simplex/FileTransfer/Server.hs`) + +The entire server change is parameterizing the existing `processHello` with `Maybe C.PrivateKeyX25519`. Zero new functions. + +#### Current code (lines 165-191): + +```haskell +xftpServerHandshakeV1 chain serverSignKey sessions + XFTPTransportRequest {thParams = thParams0@THandleParams {sessionId}, reqBody = HTTP2Body {bodyHead}, sendResponse, sniUsed, addCORS} = do + s <- atomically $ TM.lookup sessionId sessions + r <- runExceptT $ case s of + Nothing -> processHello + Just (HandshakeSent pk) -> processClientHandshake pk + Just (HandshakeAccepted thParams) -> pure $ Just thParams + either sendError pure r + where + processHello = do + challenge_ <- + if + | B.null bodyHead -> pure Nothing + | sniUsed -> do + XFTPClientHello {webChallenge} <- liftHS $ smpDecode bodyHead + pure webChallenge + | otherwise -> throwE HANDSHAKE + (k, pk) <- atomically .

Verified on Hackage: `requestHeaders :: Request -> HeaderTable`, `tokenKey :: Token -> CI ByteString`. + +### 3.2 Re-handshake flow + +When `webHello` is true in `HandshakeAccepted` state: + +1. `processHello (serverPrivKey <$> thAuth thParams)` is called with `Just pk` (existing private key) +2. `(k, pk) <- pure (C.publicKey pk, pk)` — reuses same key pair, no generation +3. `TM.insert sessionId (HandshakeSent pk) sessions` — transitions state back to `HandshakeSent` with same `pk` +4. Server sends `ServerHandshake` response (same format as initial handshake) +5. Client sends `ClientHandshake` on next stream → enters `Just (HandshakeSent pk) -> processClientHandshake pk` → normal flow +6. `processClientHandshake` stores `HandshakeAccepted thParams` with same `serverPrivKey = pk` + +### 3.3 Web client change (`xftp-web/src/client.ts`) + +Add optional `headers?` parameter to `Transport.post()`, thread it through `fetch()` and `session.request()`, and pass `{"xftp-web-hello": "1"}` in the ClientHello call in `connectXFTP`. + +### 3.4 What does NOT change + +- **CORS**: Already has `Access-Control-Allow-Headers: *` (Server.hs:106). +- **Native Haskell client**: Uses `[]` headers. No header = existing behavior. +- **Protocol wire format**: ClientHello, ServerHandshake, ClientHandshake, commands — all unchanged. +- **`processRequest`**, **`processClientHandshake`**, **`sendError`**, **`encodeXftp`** — unchanged. + +### 3.5 Haskell test (`tests/XFTPServerTests.hs`) + +Add `testWebReHandshake` next to the existing `testWebHandshake` (line 504). It reuses the same SNI + HTTP/2 setup pattern, performs a full handshake, then sends a second ClientHello with the `xftp-web-hello` header on the same connection and verifies the server responds with a valid ServerHandshake (same `sessionId`), then completes the second handshake. + +```haskell +-- Register in xftpServerTests (after line 86): +it "should re-handshake on same connection with xftp-web-hello header" testWebReHandshake + +-- Test (after testWebHandshake): +testWebReHandshake :: Expectation +testWebReHandshake = + withXFTPServerSNI $ \_ -> do + Fingerprint fp <- loadFileFingerprint "tests/fixtures/ca.crt" + let keyHash = C.KeyHash fp + cfg = defaultTransportClientConfig {clientALPN = Just ["h2"], useSNI = True} + runTLSTransportClient defaultSupportedParamsHTTPS Nothing cfg Nothing "localhost" xftpTestPort (Just keyHash) $ \(tls :: TLS 'TClient) -> do + let h2cfg = HC.defaultHTTP2ClientConfig {HC.bodyHeadSize = 65536} + h2 <- either (error . show) pure =<< HC.attachHTTP2Client h2cfg (THDomainName "localhost") xftpTestPort mempty 65536 tls + g <- C.newRandom + -- First handshake (same as testWebHandshake) + challenge1 <- atomically $ C.randomBytes 32 g + let helloReq1 = H2.requestBuilder "POST" "/" [] $ byteString (smpEncode (XFTPClientHello {webChallenge = Just challenge1})) + resp1 <- either (error . show) pure =<< HC.sendRequest h2 helloReq1 (Just 5000000) + shs1 <- either error pure $ smpDecode =<< C.unPad (bodyHead (HC.respBody resp1)) + let XFTPServerHandshake {sessionId = sid1} = shs1 + clientHsPadded <- either (error . show) pure $ C.pad (smpEncode (XFTPClientHandshake {xftpVersion = VersionXFTP 1, keyHash})) xftpBlockSize + resp1b <- either (error . show) pure =<< HC.sendRequest h2 (H2.requestBuilder "POST" "/" [] $ byteString clientHsPadded) (Just 5000000) + B.length (bodyHead (HC.respBody resp1b)) `shouldBe` 0 + -- Second handshake on same connection with xftp-web-hello header + challenge2 <- atomically $ C.randomBytes 32 g + let helloReq2 = H2.requestBuilder "POST" "/" [("xftp-web-hello", "1")] $ byteString (smpEncode (XFTPClientHello {webChallenge = Just challenge2})) + resp2 <- either (error . show) pure =<< HC.sendRequest h2 helloReq2 (Just 5000000) + shs2 <- either error pure $ smpDecode =<< C.unPad (bodyHead (HC.respBody resp2)) + let XFTPServerHandshake {sessionId = sid2} = shs2 + sid2 `shouldBe` sid1 -- same TLS connection → same sessionId + -- Complete second handshake + resp2b <- either (error . show) pure =<< HC.sendRequest h2 (H2.requestBuilder "POST" "/" [] $ byteString clientHsPadded) (Just 5000000) + B.length (bodyHead (HC.respBody resp2b)) `shouldBe` 0 +``` + +The only difference from `testWebHandshake`: the second `helloReq2` passes `[("xftp-web-hello", "1")]` instead of `[]`.

Tab A has active command streams (e.g., FPUT upload in progress) +2. Tab B sends ClientHello with header +3. Server reads `HandshakeAccepted` atomically for both streams +4. Tab A's stream already has its `thParams` snapshot → proceeds with `processRequest` using old `thParams` +5. Tab B's stream triggers `processHello (Just pk)` → stores `HandshakeSent pk` (same pk!) +6. Tab A's in-progress FPUT continues with snapshot `thParams` → completes normally (same `serverPrivKey`) +7. Tab A's NEXT command reads `HandshakeSent` from TMap → enters `processClientHandshake` → fails (command body ≠ ClientHandshake format) → HANDSHAKE error + +**Tab A's in-flight commands succeed. Tab A's subsequent commands fail with HANDSHAKE error.** This is the inherent multi-tab problem — unavoidable with per-connection session state and HTTP/2 connection sharing. The failure is clean (HANDSHAKE error, not silent corruption). + +## 6. Security Considerations + +- **No new key material**: Re-handshake reuses existing `serverPrivKey`. No opportunity for key confusion or downgrade. +- **Identity re-verification**: Server re-signs the web challenge with its long-term signing key. Client verifies identity again. +- **Header cannot escalate privileges**: The header only triggers re-handshake (which the server was already capable of doing on first connection). It does not bypass any authentication. +- **Timing**: Re-handshake takes the same code path as initial handshake, so timing side-channels are unchanged. diff --git a/rfcs/2026-02-05-xftp-web-e2e-tests.md b/rfcs/2026-02-05-xftp-web-e2e-tests.md deleted file mode 100644 index 355f76df6..000000000 --- a/rfcs/2026-02-05-xftp-web-e2e-tests.md +++ /dev/null @@ -1,1196 +0,0 @@ -# XFTP Web Page E2E Tests Plan - -## Table of Contents - -1.
