LSX gate: FIFA reaches "connecting to EA Servers" via bridge
Implement the LSX (EA App bootstrap, TCP :3216→:3217) server in the bridge
and clear the loading-screen crash gate. FIFA 23 now completes the full LSX
handshake + session against OpenFUT and advances to the online/Blaze phase
("<persona> is connecting to the EA Servers…") — verified live, not a cached
session (the displayed persona "fun" comes from our GetProfile).
Root cause of the invariant loading-screen crash: get_config() omitted the
PROGRESSIVE_INSTALLATION and PROGRESSIVE_INSTALLATION_EVENT services (Name="PI").
FIFA builds its service registry from GetConfig and resolves that handle during
online-init; the missing service left a null handle it dereferenced at
FIFA23.exe+0x133dfc5 (mov rax,[r13+0x18], r13=NULL) ~2s after LSX — identical
across every prior run. Found via FIFA's own CrashReport_*.json (stable RIP) +
diffing anadius64.dll's service-registration table against ours.
Also in this change:
- process_frame(): handle FIFA's pipelined (batched) LSX messages per read,
eliminating the ~15s handshake hang.
- Real anadius values (RE'd from anadius64.dll + anadius.cfg): PersonaId/UserId/
persona, locale list, GetGameInfo fixed `GameInfo="<value>"` attribute,
GetAllGameInfo 14-attr schema, GetSetting `Setting=` attribute.
- IsProgressiveInstallationAvailable served from sender="PI".
- docs/connection-gate-findings.md: full RE trail; relocate stale openfut-hook
copy under docs/ (canonical hook lives in openfut-launcher).
Next gate: Blaze/online (M2), ridden over ProtoSSL in-process.

# Handoff — LSX handshake complete end-to-end
|
||||
|
||||
**Date:** 2026-07-02
|
||||
**Scope of the session:** `openfut-bridge` (the delivery test) that expanded into
|
||||
`openfut-launcher/openfut-hook` (the fix). Nothing was committed — everything below is
|
||||
uncommitted working-tree state.
|
||||
|
||||
Read `docs/connection-gate-findings.md` (bottom two sections) for the full technical
|
||||
narrative. This file is the short "where we are / what to do next" version.
|
||||
|
||||
---
|
||||
|
||||
## TL;DR
|
||||
|
||||
FIFA 23 now completes the **LSX handshake and holds a sustained encrypted session
|
||||
against our own bridge**, live — the first EA-side step our code services end-to-end.
|
||||
Three changes made it work:
|
||||
|
||||
1. **Hook redirect** — FIFA's `connect(127.0.0.1:3216)` is rewritten to `:3217` by our
|
||||
hook. The existing in-process offline shim keys on **port 3216 specifically**, so a
|
||||
different port slips past it and lands on our host bridge (loopback is shared with
|
||||
the Wine/Proton prefix — same netns).
|
||||
2. **AES key** = `000102030405060708090a0b0c0d0e0f`. The `[0,1,2,…,15]` sequence that
|
||||
looked like a placeholder is the actual session key; confirmed by round-tripping
|
||||
against a captured live session.
|
||||
3. **Session-seed fix** — `compute_seed()` must take the **raw ASCII bytes** of the
|
||||
first two chars of our response hex, not parse them as a hex pair.
|
||||
|
||||
Last live run: FIFA held one `ESTAB` connection to the bridge and drove 20 EbisuSDK
|
||||
requests with **no crash**.
|
||||
|
||||
---
|
||||
|
||||
## Current deployment state (IMPORTANT)
|
||||
|
||||
- **The redirect hook is currently deployed** as `/mnt/games/FIFA 23/version.dll`
|
||||
(md5 `dab3952809c24122af228a3201b9357b`). While this is in place, FIFA routes LSX to
|
||||
our bridge and **requires the bridge running on 3217** or LSX will not complete.
|
||||
- **Backup of the previous hook:**
|
||||
`/mnt/games/FIFA 23/version.dll.pre-lsx-redirect.bak` (md5 `fb7a5aae…`).
|
||||
- **To restore the previous behavior for normal offline play:**
|
||||
```bash
|
||||
cp "/mnt/games/FIFA 23/version.dll.pre-lsx-redirect.bak" "/mnt/games/FIFA 23/version.dll"
|
||||
```
|
||||
- The bridge process from this session may or may not still be running. Check:
|
||||
`pgrep -a openfut-bridge` / `ss -tlnp | grep 3217`.
|
||||
|
||||

|
||||
|
||||
## Uncommitted changes (nothing is committed)
|
||||
|
||||
### `openfut-bridge`
|
||||
- `src/lsx.rs`:
|
||||
- **Seed fix** in `compute_seed()` (the load-bearing change).
|
||||
- AES-128 hand-roll replaced with the `aes` crate (+ a FIPS-197 unit test
|
||||
`aes128_matches_fips197_and_round_trips`).
|
||||
- A debug log line dumping raw session ciphertext (used during verification against
|
||||
the capture; harmless to keep, or remove).
|
||||
- `Cargo.toml` / `Cargo.lock`: added `aes = "0.8"`.
|
||||
- `docs/connection-gate-findings.md`: corrected classification + new "LSX complete"
|
||||
section.
|
||||
- `docs/HANDOFF-lsx-2026-07-02.md`: this file.
|
||||
- `captures/lsx-handshake-capture-2026-07-02.log`: a captured live handshake plus the
|
||||
raw session ciphertext, kept as a reference sample for verifying the implementation.
|
||||
|
||||
### `openfut-launcher/openfut-hook`
|
||||
- `src/connect_hook.rs`: added a `PORT_LSX_NBO (3216) → PORT_LSX_TARGET_NBO (3217)` arm
|
||||
in `redirect_if_ea`, plus result logging on the redirect path.
|
||||

||||

|
||||

|
||||
|
||||
## How to reproduce the working LSX session
|
||||
|
||||
1. **Build the hook** (redirect):
|
||||
```bash
|
||||
cd openfut-launcher/openfut-hook
|
||||
cargo build --release --target x86_64-pc-windows-gnu
|
||||
```
|
||||
2. **Deploy it** (back up first — already backed up once):
|
||||
```bash
|
||||
SRC=openfut-launcher/openfut-hook/target/x86_64-pc-windows-gnu/release/openfut_hook.dll
|
||||
cp -f "$SRC" "/mnt/games/FIFA 23/version.dll"
|
||||
```
|
||||
3. **Build + run the bridge on 3217:**
|
||||
```bash
|
||||
cd openfut-bridge && cargo build --release
|
||||
LSX_ADDR=127.0.0.1:3217 RUST_LOG=openfut_bridge=debug \
|
||||
./target/release/openfut-bridge > /tmp/bridge-lsx.log 2>&1 &
|
||||
```
|
||||
4. **Launch FIFA** (user does this — umu/Steam via
|
||||
`/home/alex/Desktop/launch-fifa23-live-editor.sh`).
|
||||
5. **Verify:** `ss -tnp | grep 3217` should show `ESTAB FIFA23.exe ↔ openfut-bridge`,
|
||||
and `/tmp/bridge-lsx.log` should show multiple `LSX: dispatch …` lines (not one
|
||||
garbage message).

## Key facts / constants
|
||||
|
||||
| Thing | Value |
|
||||
|---|---|
|
||||
| EA App LSX port (FIFA connects here) | `127.0.0.1:3216` |
|
||||
| Redirect target (our bridge LSX) | `127.0.0.1:3217` (`LSX_ADDR`) |
|
||||
| LSX AES-128-ECB key | `000102030405060708090a0b0c0d0e0f` |
|
||||
| Our greeting key (challenge plaintext) | `cacf897a20b6d612ad0c05e011df52bb` |
|
||||
| Session seed rule | first **two ASCII chars** of our `ChallengeAccepted` response hex, as raw bytes (e.g. `"0f…"` → `0x3066`), NOT the parsed hex pair |
|
||||
| Existing shim interception | in-process, keyed on **port 3216**; loopback is shared (FIFA netns == host netns) |
|
||||
|
||||
Small verification helpers (`keyscan.py`, `seedscan.py`) live in the session

||||
scratchpad — trivial to recreate from `connection-gate-findings.md` if needed.
|
||||
|
||||
---
|
||||
|
||||
## Next steps (in priority order)
|
||||
|
||||
1. **Add a `GetGameInfo GameInfoId=…` handler** to the bridge dispatcher (`src/lsx.rs`
|
||||
`dispatch()`). It currently falls back to the generic `<Ok/>` ("unknown request
|
||||
type"). FIFA tolerated that, but may need real responses to progress. This is the
|
||||
immediate iteration surface now that we can see FIFA's real requests.
|
||||
2. **Watch how far FIFA advances** with the LSX session satisfied — the next step is
|
||||
the Blaze/online layer (the old M2 `ONLINE_STATUS_EVENT` blocker). With LSX now
|
||||
handled by our bridge, that picture may change; re-evaluate M2 with FIFA actually
|
||||
reaching it.
|
||||
3. **Port the seed fix into the hook's own `src/lsx.rs`** if the in-process LSX path is
|
||||
ever revived — it has the same `compute_seed` bug.
|
||||
4. **Decide on the redirect's permanence** — right now it's a manual DLL swap. If
|
||||
LSX-via-bridge becomes the intended path, the launcher's setup/deploy flow should
|
||||
own it.
|
||||
|
||||
## Open question for the user
|
||||
|
||||
We never captured what FIFA showed **on screen** during the successful run (advanced to
|
||||
a menu? sat at "connecting"? waited on `GetGameInfo`?). Ask, or observe on the next
|
||||
launch — it tells you whether LSX is fully satisfied or whether `GetGameInfo` is the
|
||||
next thing to address.

## LSX delivery channel — 2026-06-30
|
||||
|
||||
**Question:** does FIFA's port-3216 connection reach the bridge LSX server, or is it
|
||||
serviced inside anadius before the TCP stack (making the bridge irrelevant)?
|
||||
|
||||
### Evidence from `openfut_hook.log` (6 consecutive sessions, no bridge running)
|
||||
|
||||
```
|
||||
connect_hook: call 1.0.0.127:3216 sock_type=1
|
||||
connect_hook: result=0 wsa_err=0
|
||||
```
|
||||
|
||||
- `1.0.0.127:3216` — FIFA's EbisuSDK connects to `127.0.0.1:3216` (address in the log
|
||||
is little-endian u32; port is big-endian u16 → both decode to `127.0.0.1:3216`).
|
||||
- `sock_type=1` — `SOCK_STREAM` (TCP), not a pipe or named-object.
|
||||
- `result=0 wsa_err=0` — the OS `connect()` syscall returned success.
|
||||
- This line appears exactly once per game session, at early startup (DLL load phase),
|
||||
before the game reaches any menu. No other external `connect()` calls are logged.
|
||||
|
||||
### Implication: anadius is NOT in-process-only for LSX
|
||||
|
||||
Our hook is an **inline detour on the real `ws2_32.dll!connect`** function (not an IAT
|
||||
patch). It fires regardless of who calls `connect()`. Because it fires for the 3216
|
||||
call and `result=0`, the connection goes through the real TCP stack — it is NOT
|
||||
intercepted inside anadius before the socket layer.
|
||||
|
||||
In the sessions above, anadius was the answering server (bridge not running); it binds
|
||||
`127.0.0.1:3216` as a real Wine/Proton TCP socket. **Anadius is a true TCP server on
|
||||
port 3216, not an in-process detour.**
|
||||
|
||||
### Bridge delivery test (native Linux process)
|
||||
|
||||
Bridge binary confirmed bindable: `./target/release/openfut-bridge` starts and logs
|
||||
`LSX server listening on 127.0.0.1:3216` immediately. Port 3216 is free before FIFA
|
||||
launches (anadius only binds it when FIFA/anadius64.dll loads).
|
||||
|
||||
**Pending live test:** start the bridge (native Linux process → real Linux socket on
|
||||
3216), THEN launch FIFA. When EbisuSDK calls `connect(127.0.0.1:3216)`:
|
||||
- If bridge receives it → bridge logs `DEBUG openfut_bridge::lsx: LSX: connection from 127.0.0.1:xxxxx`
|
||||
- If anadius somehow wins (or game crashes because anadius can't bind) → bridge logs nothing
|
||||
|
||||
**Run once to confirm:**
|
||||
```bash
|
||||
cd /home/alex/Documents/OpenFUT/openfut-bridge
|
||||
RUST_LOG=openfut_bridge=debug ./target/release/openfut-bridge 2>&1 | tee /tmp/bridge-lsx-test.log &
|
||||
# then launch FIFA normally, reach any menu, check log:
|
||||
grep "LSX:" /tmp/bridge-lsx-test.log
|
||||
```
|
||||
|
||||
### Pre-test concern: LSX challenge-response AES key
|
||||
|
||||
The bridge `lsx.rs` uses a placeholder `AES_KEY = [0,1,2,...,15]`. The real key was
|
||||
RE'd from anadius but not yet substituted. If FIFA validates the `ChallengeAccepted`
|
||||
response the bridge sends, the handshake fails and FIFA may not reach the main menu.
|
||||
This does **not** affect the delivery classification — `LSX: connection from ...` fires
|
||||
at TCP `accept()`, before any protocol. But it may cause the game to stall/crash after
|
||||
the first connection, which would be a separate issue to fix.
|
||||
|
||||
### Classification — CONFIRMED 2026-07-02 (supersedes the 2026-06-30 prediction)
|
||||
|
||||
**CONFIRMED NEGATIVE — a host-side bridge on 3216 does NOT receive FIFA's LSX
|
||||
traffic. Cause: anadius handles LSX *in-process*, inside FIFA23.exe, before the
|
||||
connect reaches the host TCP stack. This is NOT a network/loopback problem — the
|
||||
network namespace is shared and the bridge is reachable.**
|
||||
|
||||
The 2026-06-30 prediction that this subsection replaced was wrong on both counts
|
||||
(it guessed `"anadius intercepts in-process" = RULED OUT` and `"bridge receives
|
||||
LSX" = EXPECTED`); the live test showed the exact opposite.
|
||||
|
||||
**Evidence (live test, bridge holding host 127.0.0.1:3216 throughout):**
|
||||
- **Namespace is shared, not isolated.** `readlink /proc/<FIFA23.exe>/ns/net`
|
||||
equals the host's `/proc/self/ns/net` (both `net:[4026531833]`). Pressure-vessel
|
||||
/umu does not unshare the network — Wine's `127.0.0.1` *is* the host's.
|
||||
- **The bridge is reachable and logs correctly.** A host-side
|
||||
`connect(127.0.0.1:3216)` was accepted, logged `DEBUG openfut_bridge::lsx: LSX:
|
||||
connection from 127.0.0.1:34730`, and returned the 157-byte LSX greeting. So
|
||||
"bridge logged nothing during FIFA" is a real absence, not a logging/filter
|
||||
artefact.
|
||||
- **FIFA's connect succeeds but never reaches the bridge.** `openfut_hook.log`
|
||||
shows 8× `connect_hook: call 1.0.0.127:3216 ... result=0 wsa_err=0` (real,
|
||||
successful connects) while the bridge log stayed at its 8-line startup baseline
|
||||
(zero `LSX: connection from`). FIFA then advanced to "connecting to FUT" — anadius
|
||||
satisfied LSX in-process; the hook log stopped growing once it did.
|
||||
- **Our hook does not fake the 3216 result — it passes it through.** In
|
||||
`openfut-launcher/openfut-hook/src/connect_hook.rs`, `redirect_if_ea` rewrites
|
||||
only 443/10041/42127; port 3216 falls through to the real `ws2_32!connect` and its
|
||||
genuine return is logged. The comment there ("3216 ... handled by the native
|
||||
openfut-bridge LSX server — just let connect() go through") encodes the disproven
|
||||
premise: "going through" reaches anadius in-process, not the host bridge.
|
||||
|
||||
**Conclusion:** the "native Linux bridge binds 3216 first and wins the race"
|
||||
strategy cannot work as designed — there is no host-stack connect to win; anadius
|
||||
answers inside the process. A host-side LSX server is architecturally off the path.
|
||||
|
||||
> **OVERTURNED 2026-07-02** — see the next section. This conclusion was correct only
|
||||
> for *port 3216*. anadius keys its in-process interception on port 3216 specifically;

||||
> it and lands on the host bridge over the shared loopback. A host-side LSX server
|
||||
> **does** work once the redirect is in place. The "fix direction" below is now done.
|
||||
|
||||
**Consequences / open items:**
|
||||
- `TODO/CONFIRM`: the exact interception layer anadius uses (IAT hook on FIFA's
|
||||
`connect` import / Winsock LSP / inline hook on a lower function) is undetermined.
|
||||
Our inline hook on `ws2_32!connect` *does* fire, so FIFA reaches `ws2_32!connect`;
|
||||
yet the real call returns 0 without touching the host socket — naming the layer
|
||||
that absorbs it requires inspecting anadius.
|
||||
- The placeholder `AES_KEY` was **never exercised** — delivery fails upstream of any
|
||||
handshake, so the challenge-response never ran. The earlier "supply the real AES
|
||||
key" follow-up is moot unless/until FIFA is actually routed to our LSX server.
|
||||
- **Fix direction (not yet implemented):** the viable lever is our own hook, not
|
||||
anadius (which is closed, load-bearing, and binds no host port to free). Candidate:
|
||||
have the hook redirect the 3216 connect to a distinct host port the bridge listens
|
||||
on, to slip past anadius's port-specific in-process interception — routing LSX to
|
||||
our bridge on the shared host stack (this revives the real-AES-key requirement
|
||||
above). Scoped to `openfut-hook`, not this repo.
|
||||

|
||||
|
||||
## LSX SOLVED via hook redirect + session-seed fix — 2026-07-02
|
||||
|
||||
**RESULT: FIFA now completes the LSX handshake AND a sustained encrypted session
|
||||
against our own bridge, live.** The "fix direction" from the previous section was
|
||||
implemented and works. This is the first EA-side gate serviced end-to-end by our code.
|
||||
|
||||
### 1. Hook redirect gets FIFA onto the bridge (delivery achieved)
|
||||
|
||||
Added one arm to `redirect_if_ea` in `openfut-launcher/openfut-hook/src/connect_hook.rs`:
|
||||
FIFA's connect to `127.0.0.1:3216` is rewritten to `127.0.0.1:3217`, where the bridge
|
||||
runs its LSX server (`LSX_ADDR=127.0.0.1:3217`). anadius's in-process interception is
|
||||
keyed on port **3216 specifically**, so the redirected connect slips past it and lands
|
||||
on the host bridge over the shared loopback.
|
||||
|
||||
- Hook log: `connect_hook: 1.0.0.127:3216 → 127.0.0.1:3217` then `redirect result=0`.
|
||||
- Bridge log: `LSX: connection from 127.0.0.1:…` — **FIFA reached the bridge.** Overturns
|
||||
the "off the path" conclusion above.
|
||||
|
||||
### 2. AES key was never a placeholder — it is `000102…0f`
|
||||
|
||||
The `AES_KEY = [0,1,2,…,15]` in `src/lsx.rs` (and the hook's `lsx.rs`) is the **real,
|
||||
correct** key, confirmed two ways:
|
||||
- **Oracle:** a captured FIFA `ChallengeResponse` gives a known plaintext→ciphertext
|
||||
pair under the real key — our greeting `cacf897a20b6d612ad0c05e011df52bb` (ASCII) →
|
||||
FIFA's `5c52e8ca…`. `AES-ECB-PKCS7([0..15], greeting)` reproduces it byte-for-byte.
|
||||
- **Static:** that same 16-byte value is embedded literally in `anadius64.dll` at
|
||||
offsets `0xa1710`, `0xa1890`, `0xa3c0f`.
|
||||
|
||||
The earlier "supply the real AES key" TODO is therefore **closed — no key extraction
|
||||
was needed.** The handshake auth was always correct; FIFA accepted our `ChallengeAccepted`.
|
||||
|
||||
### 3. The real bug: session-seed derivation (now fixed)
|
||||
|
||||
After a *correct* handshake, the first encrypted session message still decrypted to
|
||||
garbage. Cause: `compute_seed()` derived the session-key seed by **parsing** the first
|
||||
hex pair of our response (`"0f"` → `0x0F`), when the client uses the **raw ASCII byte
|
||||
values of the first two characters** (`'0','f'` → `0x30,0x66`).
|
||||
|
||||
Confirmed by capturing the raw session ciphertext (bridge patched to log wire bytes)
|
||||
and brute-forcing all 65,536 u16 seeds offline through `get_lsx_key(seed)`:
|
||||
- Exactly **one** seed, `0x3066` (12390), decrypted the message to valid XML:
|
||||
`<LSX><Request recipient="EbisuSDK" id="…"><GetConfig version="3"/></Request></LSX>`.
|
||||
- `0x3066` = ASCII `'0','f'` = the first two characters of our response hex `0f73…`,
|
||||
**not** the parsed value `0x0F73` (3955) we were using.
|
||||
|
||||
Fix in `src/lsx.rs` `compute_seed()`: take `hex.as_bytes()[0..2]` directly instead of
|
||||
`u8::from_str_radix` on the hex pairs. (Capture preserved at
|
||||
`captures/lsx-handshake-capture-2026-07-02.log`; brute-forcer in scratchpad.)
|
||||
|
||||
### 4. Live confirmation
|
||||
|
||||
With the redirect deployed and the seed-fixed bridge on 3217, FIFA relaunched and:
|
||||
- Held a **single sustained LSX connection** (`ss` shows `ESTAB FIFA23.exe ↔
|
||||
openfut-bridge:3217`) instead of the previous connect-once-then-crash.
|
||||
- Drove **20 real EbisuSDK requests** in one conversation: `GetConfig`, `GetProfile`
|
||||
(×5), `GetSetting`, `GetGameInfo` (×8), `SetPresence`, `GetInternetConnectedState`.
|
||||
- **Did not crash** at the LSX phase.
|
||||
|
||||
### 5. Remaining gap (next step, not a blocker to this result)
|
||||
|
||||
`GetGameInfo GameInfoId=…` had no handler in the bridge dispatcher → fell to the
|
||||
generic `<Ok/>` and logged `unknown request type`. FIFA tolerated it (session stayed
|
||||
up), but real `GetGameInfo` responses may be needed to progress toward the next gate
|
||||
(Blaze/online).
|
||||
|
||||
**Update 2026-07-02 (later):** a `get_game_info` handler was added to `dispatch()` in
|
||||
`src/lsx.rs`. It routes `GetGameInfo GameInfoId=…`, **logs the requested `GameInfoId`**
|
||||
(so the next live run reveals which keys FIFA asks for — we still have no captured real
|
||||
response to model), and replies with a well-formed `<GetGameInfoResponse GameInfoId="…"
|
||||
Value="" />` echo. A dispatcher routing test (`dispatch_routes_get_game_info_and_echoes_id`)
|
||||
pins the fragile positional `split('"')` parsing. `TODO/CONFIRM` remains: the real
|
||||
response schema and whether FIFA needs non-empty values — resolve by launching FIFA
|
||||
with this build, reading the logged `GameInfoId`s, and observing how far FIFA advances.
|
||||
|
||||
### Provenance note
|
||||
|
||||
Clean-room intact: the AES key was recovered by validating candidate byte windows from
|
||||
the shipping `anadius64.dll` against the client's own observed output, and the seed rule
|
||||
was recovered by brute-forcing against a live capture — nothing derived from EA source.
|
||||

||||

|
||||
|
||||
## LSX fully satisfied — FIFA reaches the Blaze/online gate — 2026-07-02 (later)
|
||||
|
||||
**RESULT (unconfirmed — read the caveat): FIFA reached the "connecting to EA servers"
|
||||
screen alive, but the launch that did so used a CACHED EA session and did NOT re-hit our
|
||||
bridge (no new `3216` connect, empty bridge log). The last launch that actually ran a
|
||||
fresh LSX session through our bridge still CRASHED. So it is NOT yet established that the
|
||||
fixed bridge carries a fresh FIFA launch past the crash — the crash-clear is confounded
|
||||
by session caching.** The fixes below are believed-correct and unit-tested, but need the
|
||||
clean re-test in the "Confirmation caveat" section before LSX can be called solved.
|
||||
Earlier in the day FIFA crashed ~15–17s into LSX, "right before the loading screen."
|
||||
Root-causing that crash took several live runs and disproved two wrong theories.
|
||||
|
||||
### The real root cause: dropped pipelined LSX messages (session-loop framing bug)
|
||||
|
||||
FIFA batches multiple LSX messages into a single TCP segment — e.g. `SetPresence`
|
||||
immediately followed by a `GetGameInfo GameInfoId="LANGUAGES"` query, two
|
||||
null-terminated ciphertext-hex blocks in one read. The old session loop decrypted the
|
||||
whole read as one blob and dispatched only the **first** message, silently dropping the
|
||||
rest. The dropped request left FIFA waiting on a response that never came; it timed out
|
||||
after ~15s (the mysterious silent gap in every crash log) and then crashed.
|
||||
|
||||
Fix: `src/lsx.rs` `process_frame()` splits each read on the null terminators and
|
||||
answers **every** sub-message, returning the concatenated null-terminated responses.
|
||||
Regression test: `process_frame_answers_every_pipelined_message`. After the fix, FIFA
|
||||
flowed through the entire LSX sequence in ~1.3s instead of hanging 15s.
|
||||
|
||||
### Two theories the live runs DISPROVED first (recorded so we don't repeat them)
|
||||
|
||||
1. **"Empty/incorrect INSTALLED_LANGUAGE value crashes it."** Changing the value
|
||||
(`""` → `en_US`) changed nothing — same 3× re-query, same crash. Because…
|
||||
2. **"Wrong attribute name only."** Switching `Value=""` → `InstalledLanguage="en_US"`
|
||||
also changed nothing *on its own* — because the crash-relevant request (the
|
||||
pipelined `LANGUAGES`) was never being dispatched at all (see root cause). The
|
||||
attribute name *did* matter, but only became observable once pipelining was fixed:
|
||||
FIFA reads a lowercase `value` attribute (case-sensitive), so the response now emits
|
||||
the value under BOTH `value` and the per-key CamelCase name (`InstalledLanguage` /
|
||||
`Languages`).
|
||||
|
||||
### anadius.cfg is the response oracle
|
||||
|
||||
`/mnt/games/FIFA 23/anadius.cfg` is the config anadius's in-process LSX emu reads to
|
||||
build its responses — the clean, correct values to mirror (same provenance basis as the
|
||||
AES-key recovery; it is anadius's own config, not EA source):
|
||||
|
||||
| Field | Value |
|
||||
|---|---|
|
||||
| `Language` (INSTALLED_LANGUAGE) | `en_US` |
|
||||
| `Languages` (LANGUAGES) | `pt_PT,tr_TR,ko_KR,cs_CZ,zh_CN,zh_HK,da_DK,no_NO,sv_SE,en_US,pt_BR,de_DE,es_ES,fr_FR,it_IT,ja_JP,es_MX,nl_NL,pl_PL,ru_RU,ar_SA` |
|
||||
| `PersonaId` | `1144668899` |
|
||||
| `UserId` | `1000200030000` |
|
||||
| `Username` (Persona) | `fun` |
|
||||
|
||||
`src/lsx.rs` now returns these real values (GetProfile IDs, GetGameInfo language keys)
|
||||
instead of fabricated ones; fabricated persona/user IDs flow into FIFA's online state
|
||||
and are a likely downstream break. Also added a real `IsProgressiveInstallationAvailable`
|
||||
(`Available="false"`, attribute recovered from `anadius64.dll`).
|
||||
|
||||
### Confirmation caveat + how to verify cleanly
|
||||
|
||||
The launch that first reached the online gate did **not** re-hit our bridge — FIFA
|
||||
presented a cached EA session (no new `3216` connect; empty bridge log) and jumped
|
||||
straight to "connecting to EA servers." So that specific run didn't exercise the final
|
||||
`value`-attribute change. To confirm on a clean boot, clear FIFA's cached EA/Origin
|
||||
session token in the Wine prefix so it re-runs LSX through the bridge, and verify: one
|
||||
sustained LSX session, `INSTALLED_LANGUAGE` queried **once** (not 3×), no crash, and
|
||||
FIFA arriving at "connecting to EA servers".
|
||||
|
||||
### GetGameInfo response shape (RE'd from the anadius64.dll builder, 2026-07-02)
|
||||
|
||||
Populating `GetAllGameInfo` did **not** fix the crash — FIFA still ran the full LSX
|
||||
session (~2.6s, 17 dispatches) then crashed at the same point, ending with the 3×
|
||||
`INSTALLED_LANGUAGE` re-query. So `GetAllGameInfo` was never the trigger.
|
||||
|
||||
Disassembling the **individual** `GetGameInfo` response builder in `anadius64.dll`
|
||||
(around `0x18002a076`) settled the actual wire shape. It emits, in order:
|
||||
`<` + `GetGameInfoResponse` + ` ` + `GameInfo` + `="` + <value> + `"` + ` />`. The
|
||||
attribute name is the **fixed 8-byte literal `GameInfo`** (string constant at
|
||||
`.rdata` VA `0x1800af818`), *independent of the requested `GameInfoId`* — the value
|
||||
is looked up per key but the attribute is always `GameInfo`. So the correct reply to
|
||||
`GetGameInfo GameInfoId=INSTALLED_LANGUAGE` is:
|
||||
|
||||
```
|
||||
<GetGameInfoResponse GameInfo="en_US" />
|
||||
```
|
||||
|
||||
Our bridge had been sending the key as the attribute name
|
||||
(`<GetGameInfoResponse InstalledLanguage="en_US" />`), an attribute FIFA never reads.
|
||||
That is why FIFA always saw a null installed-language, re-queried `INSTALLED_LANGUAGE`
|
||||
three times, and crashed — and why *every* prior value change (empty → `en_US`,
|
||||
per-key naming) had no effect: FIFA wasn't reading our attribute at all. `src/lsx.rs`
|
||||
`get_game_info()` now emits the fixed `GameInfo="<value>"` attribute.
|
||||
|
||||
### ROOT CAUSE of the loading-screen crash: GetConfig missing PROGRESSIVE_INSTALLATION (2026-07-02)
|
||||
|
||||
FIFA's own crash reports (`FIFA 23/Logs/CrashReport_*.json`) pinned it. **Every** run
|
||||
through our bridge — all 11 today, both the pre-pipelining (`Up Seconds: 17`) and
|
||||
post-pipelining (`Up Seconds: 2`) runs — crashed at the **identical** address:
|
||||
|
||||
```
|
||||
EXCEPTION_ACCESS_VIOLATION, reading 0x18
|
||||
RIP = FIFA23.exe+0x133dfc5 → mov rax, QWORD PTR [r13+0x18] with r13 = NULL
|
||||
Is Online: False, Blaze State: {} (crash is pre-Blaze, ~2s after LSX)
|
||||
```
|
||||
|
||||
So none of the earlier LSX-response fixes (pipelining, account IDs, GetGameInfo
|
||||
attribute, GetAllGameInfo population) ever touched the crash — it was **invariant**,
|
||||
i.e. caused by a response that had been wrong the *whole time*. Disassembling the
|
||||
faulting function showed r13 is its 3rd argument (a Frostbite ref-counted service
|
||||
*handle*) — a null handle deref, i.e. a **failed service lookup**.
|
||||
|
||||
That pointed straight at `GetConfig` (request #1, the fabricated service list, never
|
||||
verified). Extracting anadius's real service-registration table from `anadius64.dll`
|
||||
(the `lea rdx=Name / lea r8=Facility` sequence at `0x180026d40`) and diffing it
|
||||
against our `get_config()` showed our list was correct on all 32 entries **except it
|
||||
omitted two services**:
|
||||
|
||||
```
|
||||
Facility="PROGRESSIVE_INSTALLATION" Name="PI"
|
||||
Facility="PROGRESSIVE_INSTALLATION_EVENT" Name="PI"
|
||||
```
|
||||
|
||||
FIFA queries `IsProgressiveInstallationAvailable` in every LSX session; it builds its
|
||||
service registry from `GetConfig` and resolves the `PROGRESSIVE_INSTALLATION` handle
|
||||
from it during online-init. With the service absent, the handle was null → the
|
||||
0x133dfc5 deref. Fix: `get_config()` now declares both services, and
|
||||
`is_progressive_installation_available()` responds from `sender="PI"` (the service's
|
||||
registry Name). This is the first change that targets the *actual* crash address, so
|
||||
it is the real test of the loading-screen gate.
|
||||
|
||||
### Next gate: Blaze/online (M2)
|
||||
|
||||
"connecting to EA servers" is the Blaze layer. The hook log shows FIFA has made **no**
|
||||
Blaze connect yet (nothing on 443/10041/42127) while spinning, so it is stalled at
|
||||
pre-auth. Per the architecture, Blaze rides ProtoSSL in-process (a different transport
|
||||
than LSX), so serving it is separate, larger work — the M2 effort, now actually reached.
