From c451af495c89b1dd85c75079ec48146c6459889c Mon Sep 17 00:00:00 2001 From: JSKitty Date: Mon, 16 Mar 2026 23:31:33 +0000 Subject: [PATCH 001/417] feat: replace iroh-gossip with raw QUIC for realtime channels MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Complete rewrite of Mini App realtime P2P transport — replaces the iroh-gossip epidemic protocol with direct QUIC connections via iroh's Endpoint API. This eliminates all software bottlenecks, achieving ~20,000x faster local processing and ~99% reduction in per-message framing overhead. Key changes: - Raw QUIC uni streams replace gossip broadcast (no protocol overhead) - Per-peer independent connections eliminate head-of-line blocking - Persistent streams with varint length prefix (1-3 bytes vs 39 bytes) - WebSocket fast-path for sends on macOS/Windows (~1μs per message) - Tauri invoke fallback for Linux/WebKitGTK (WS blocked on custom schemes) - Public key tie-breaker prevents simultaneous connection storms - Stream announcement resolves QUIC lazy-open timing issues - 36-byte seq+pubkey trailer removed (QUIC identifies peers natively) - iroh-gossip dependency fully removed from the project New file: rt_ws.rs — localhost WS server with 128-bit token auth for zero-overhead binary frame sends from Mini App JS. Tested bidirectionally across macOS, Linux, and Android (emulator).

From ededab30ad58d0899c63f57cd255f638e5bde374 Mon Sep 17 00:00:00 2001 From: JSKitty Date: Thu, 19 Mar 2026 01:20:15 +0000 Subject: [PATCH 002/417] feat: stabilize gossip realtime channels with preconnect, SQLite persistence, and message buffering MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major reliability and performance improvements to Mini App P2P realtime channels. Preconnect System: - Scan XDC zip for `joinRealtimeChannel` usage when opening a Mini App - If detected, pre-initialize Iroh endpoint + relay connection in background - Create gossip channel with message buffering (no data dropped before JS listener attaches) - Send peer advertisement via Nostr immediately so peers discover us early - Connect to known peers from SQLite with 5s timeout (stale peers fail fast) - Watch signal coordinates preconnect with joinRealtimeChannel (no polling, no races) - joinRealtimeChannel awaits signal then re-joins to set event target + flush buffer - Eliminates 2-5s Iroh init delay from user-perceived join time SQLite Peer Persistence: - Peer advertisements (Kind 30078) saved to events table with reference_id = topic - Peer-left signals invalidate older advertisements from same npub - On game open, query SQLite for valid (non-left-invalidated) advertisements - Survives app restarts, offline→online transitions, late joiners Gossip Transport (iroh-gossip 0.97): - Proper leave_channel cleanup: explicit drop of GossipSender before aborting subscribe loop - join_peers on NeighborUp for bidirectional topic association - NeighborDown auto-reconnect via Nostr re-advertisement after 2s delay - Malformed messages (<36-byte trailer) dropped with warning - BBR congestion control enabled via noq-proto for better relay throughput - EventTargetState with message buffer: incoming data buffered when target is None, flushed on set - Read lock on hot path for send_event (write lock only when buffering) WS Fast-Path on Android: - Moved send_handles from IrohState to RealtimeManager - ensure_ws_started() with std::net::TcpListener sync bind for Android JNI timing - Android JNI awaits preconnect signal, skips redundant peer connections when preconnect ran - 1500ms stuck-CONNECTING timeout matching desktop behavior Desktop Window Close Handler: - Full teardown: leave_channel, remove session peers, emit status, send peer-left via Nostr - Replaces old partial cleanup that kept stale channels open Cleanup: - Removed debug iroh relay patches (hundreds of warn! log lines) - Removed tracing-subscriber dependency - Removed dead rt_ws::start() function - Removed unused PeerAdvertisementRecord.created_at field - Removed duplicate peer connections (preconnect + joinRealtimeChannel were both connecting) - Fixed irrefutable if-let patterns on to_bech32() calls -

Subscribe-before-connect race fix (realtime.rs): Move peer connect() AFTER subscribe_with_opts() so the gossip actor has the topic registered when connections deliver messages. 2. Bi-directional WebSocket receive (rt_ws.rs, realtime.rs): WS was send-only. Now incoming gossip data is pushed back through the WS connection, bypassing JNI evaluateJavascript starvation. 3. Bootstrap peers in preconnect (commands.rs): Pass cached + persisted peer addresses to join_channel as bootstrap instead of joining with 0 peers and racing with try_add_peer. 4. Android overlay cleanup (commands.rs): miniapp_close and stale instance cleanup now properly tear down realtime channels, session peers, and WS senders. 5. Android CSP (MiniAppWebViewClient.kt): Added ws://127.0.0.1:* to connect-src and wasm-unsafe-eval to script-src to match desktop CSP.

What's zeroized: - PIN/password: cleared immediately after Argon2 key derivation (~100ms lifetime) - Encryption key copies: zeroed after every encrypt/decrypt call + all error paths - Plaintext input to encrypt: zeroed right after ChaCha20 reads it (nsec, seed, messages) - Mnemonic seed phrase: zeroed after persisting to DB (was session-lifetime, now seconds) Changed MNEMONIC_SEED from OnceLock to Mutex> to enable clearing - Logout: ENCRYPTION_KEY, PENDING_NSEC, and MNEMONIC_SEED all explicitly zeroed before process restart - Key generation params: raw key bytes zeroed after hex conversion Without zeroize, Rust's String/Vec drop deallocates but doesn't overwrite — sensitive bytes persist in heap until the allocator reuses that page (seconds to hours). With zeroize, the compiler cannot optimize away the volatile memory writes.

Generic scanning tools find nothing actionable. +- **Forensic imaging tools** — without a Vector-specific extraction module, standard forensic suites cannot identify key material among the vault's random data. +- **Memory dump analysis** — a raw memory dump contains 128 arrays of random values. Even with the derivation algorithm (open source), extracting keys requires brute-forcing ASLR-dependent addresses — a computationally expensive search with no shortcuts. +- **Core dump exposure** — on Linux/Android, `PR_SET_DUMPABLE=0` suppresses core dumps, preventing key material from being written to disk on crash. On macOS, `PT_DENY_ATTACH` prevents third-party memory capture. On Windows, the DACL blocks external memory reads. +- **Swap file / hibernation** — if pages are swapped to disk under memory pressure (possible on all platforms since mlock is not used), key shares exist as individual `usize` values indistinguishable from random data. An attacker with a swap file would face the same brute-force as a memory dump. + +### Resistant to (requires significant effort) + +- **Targeted reverse engineering** — an attacker with Vector's source code, the release binary, and a memory snapshot must perform manual binary analysis (hours in tools like Ghidra) to determine the runtime relationship between the vault arrays and key storage. LTO and ASLR make static layout unpredictable across builds. +- **Brute-force with source code** — with the algorithm and a memory dump, the attacker must brute-force the ASLR instance address. Computational hardening (~25 μs/attempt) limits throughput. The search space depends on platform ASLR entropy (minutes to hours, single-core). The vault is the second defensive layer — anti-debug protections prevent obtaining the dump in the first place. + +### Not protected against + +- **Code injection with elevated privileges** — an attacker who can load code into Vector's process can call the key retrieval function directly, bypassing the vault entirely. This requires either root/admin access (to override anti-debug protections), pre-launch environment control (to inject libraries before protections activate), or binary modification (to patch out the protections, invalidating the code signature). None of these can be performed by a same-privilege, post-launch process. +- **Kernel-level access** — a kernel rootkit cannot crack the vault's mathematics (it faces the same brute-force as any memory reader), but it can bypass the vault entirely by modifying Vector's code in memory to intercept keys during the brief plaintext window of signing operations, or by setting hardware breakpoints on vault access. This is an active code-modification attack, not a passive memory-reading attack. +- **Keylogging** — capturing the PIN/password before it reaches the application bypasses all memory protection. + +## Comparison with Other Messaging Applications + +Analysis performed 2026-03-23 against Signal Desktop ([`a8118faf`](https://github.com/signalapp/Signal-Desktop/tree/a8118faf0888682a53dc2cd5c11fcd0cc4a30573)), libsignal ([`a5e76674`](https://github.com/signalapp/libsignal/tree/a5e76674882a89bac1ed3f4a982120652966d21e)), and Telegram Desktop ([`ba4715a3`](https://github.com/telegramdesktop/tdesktop/tree/ba4715a3afc49554aef36a67335c519d05701162)). + +| Protection | Vector | Signal Desktop | Telegram Desktop | +|---|---|---|---| +| Key splitting | 4 XOR shares across 128 arrays | None | None | +| Memory obfuscation | 128 decoy arrays, zero constants | None | None | +| Key zeroization | All paths (passwords, seeds, keys) | Symmetric cipher state only | DH exchange temps only | +| Anti-debug | PT_DENY_ATTACH / PR_SET_DUMPABLE / DACL | None | None | +| Anti-DLL injection | Microsoft-signed only policy (Windows) | None | None | +| Key extraction difficulty | Hours (with source + binary + snapshot) | Instant (grep for 32 bytes) | Instant (follow pointer) | + +**Signal Desktop** stores identity keys in a [plain JavaScript `Map`](https://github.com/signalapp/Signal-Desktop/blob/a8118faf0888682a53dc2cd5c11fcd0cc4a30573/ts/SignalProtocolStore.preload.ts#L249) with no memory protection. At the Rust layer, libsignal's [`PrivateKey` derives `Copy`](https://github.com/signalapp/libsignal/blob/a5e76674882a89bac1ed3f4a982120652966d21e/rust/core/src/curve.rs#L236-L239) with no `Zeroize` or `Drop` — the raw `[u8; 32]` is freely duplicated on the stack without clearing.

The key exists in plaintext only for microseconds during signing, then is dropped and zeroized. +- **No permanent key copies** — the `GuardedSigner` reads from the vault on demand, replacing the previous approach of holding a permanent `Keys` copy in memory. +- **No reusable cracker** — ASLR changes the instance address every launch, and LTO changes binary offsets every build. A cracker crafted for one version breaks on the next update, ruling out commodity tooling and redistributable extraction scripts. diff --git a/src-tauri/Cargo.lock b/src-tauri/Cargo.lock index 383837c4..51217ff6 100644 --- a/src-tauri/Cargo.lock +++ b/src-tauri/Cargo.lock @@ -502,8 +502,8 @@ source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "90dbd31c98227229239363921e60fcf5e558e43ec69094d46fc4996f08d1d5bc" dependencies = [ "bitcoin_hashes", - "rand 0.8.5", - "rand_core 0.6.4", + "rand 0.7.3", + "rand_core 0.5.1", "serde", "unicode-normalization", ] @@ -4721,9 +4721,8 @@ dependencies = [ [[package]] name = "nostr" -version = "0.44.2" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "3aa5e3b6a278ed061835fe1ee293b71641e6bf8b401cfe4e1834bbf4ef0a34e1" +version = "0.44.0" +source = "git+https://github.com/VectorPrivacy/nostr.git?branch=zeroize-secretkey#0f9f3a7ac42a0ac699b48458e87b4130c00cb54e" dependencies = [ "base64 0.22.1", "bech32", @@ -4741,6 +4740,7 @@ dependencies = [ "serde_json", "unicode-normalization", "url", + "zeroize", ] [[package]] @@ -9211,6 +9211,7 @@ dependencies = [ "iroh", "iroh-gossip", "jni", + "libc", "lofty", "mdk-core", "mdk-sqlite-storage", diff --git a/src-tauri/Cargo.toml b/src-tauri/Cargo.toml index 2d5e579b..ac800518 100644 --- a/src-tauri/Cargo.toml +++ b/src-tauri/Cargo.toml @@ -69,6 +69,7 @@ rayon = "1.11.0" # Transitive Dependencies (re-used from frameworks we already utilise, like Tauri) memchr = "2" zeroize = "1.8" +libc = "0.2" rustls = { version = "0.23", default-features = false, features = ["ring", "logging", "std", "tls12"] } # Mini Apps (WebXDC) support @@ -132,3 +133,7 @@ whisper-rs-sys = { git = "https://github.com/VectorPrivacy/whisper-rs.git", bran # pkarr uses reqwest with "rustls" feature which forces aws-lc-rs (breaks Android 11). # Patched to use "rustls-no-provider" so our ring install_default() is used instead. pkarr = { path = "patches/pkarr" } +# nostr SDK's SecretKey Drop uses non_secure_erase which the compiler can optimize away. +# Patched to use zeroize (volatile writes) so secret key bytes are guaranteed cleared from the stack. +# Fork: https://github.com/VectorPrivacy/nostr/tree/zeroize-secretkey +nostr = { git = "https://github.com/VectorPrivacy/nostr.git", branch = "zeroize-secretkey" } diff --git a/src-tauri/patches/iroh b/src-tauri/patches/iroh new file mode 160000 index 00000000..3d6e26b1 --- /dev/null +++ b/src-tauri/patches/iroh @@ -0,0 +1 @@ +Subproject commit 3d6e26b1182ecf63ce273793d44b3908117211e1 diff --git a/src-tauri/src/android/background_sync.rs b/src-tauri/src/android/background_sync.rs index 74bce59f..5d58cc07 100644 --- a/src-tauri/src/android/background_sync.rs +++ b/src-tauri/src/android/background_sync.rs @@ -16,7 +16,7 @@ use std::collections::HashSet;

This kept the mobile radio permanently active and wasted bandwidth/CPU on irrelevant traffic. Changes: - Scoped MLS subscriptions via 'h' tag: relay-side filtering by group ID, only our groups' messages are sent over the wire (foreground + background) - Single relay with failover: background connects to one relay instead of 4-5, tries each candidate in priority order (user custom relays first, then non-disabled defaults) with 500ms status polling up to 10 seconds - Replace 5-second stop-checker polling loop with tokio::sync::Notify for instant zero-cost wakeup (eliminates ~17,280 timer wakes per day) - Early bail during relay connection if user foregrounds the app Verified on device: single relay connected, scoped subscription active, group notification delivered with sender name and custom sound.

This caused missing DMs, missing profiles, and empty UI on resume. Fixes: - Clear stale relay pool and partial STATE in login_from_stored_key guard so the frontend always does a full boot with all relays and complete data - Add FULL_SESSION_INITIALIZED flag to prevent debug hot-reload from using standalone sync's partial state (only MLS groups, no DMs) - Unified MLS subscription via refresh_mls_subscription(): single sub updated in place on group join, leave, or create — never accumulates, respects relay subscription limits - Foreground MLS subscription properly skips when no groups exist (never falls back to subscribing to the entire network's MLS traffic) Co-Authored-By: Claude Opus 4.6 (1M context) --- src-tauri/src/commands/account.rs | 42 ++++++++++- src-tauri/src/commands/mls.rs | 18 ++++- .../src/services/subscription_handler.rs | 70 ++++++++++++------- 3 files changed, 98 insertions(+), 32 deletions(-) diff --git a/src-tauri/src/commands/account.rs b/src-tauri/src/commands/account.rs index def94426..aa891386 100644 --- a/src-tauri/src/commands/account.rs +++ b/src-tauri/src/commands/account.rs @@ -11,9 +11,14 @@ use nostr_sdk::prelude::*; use tauri::{AppHandle, Emitter, Manager, Runtime}; use zeroize::Zeroize; +use std::sync::atomic::AtomicBool; use crate::{STATE, TAURI_APP, NOSTR_CLIENT, MY_SECRET_KEY, MY_PUBLIC_KEY, MNEMONIC_SEED, PENDING_NSEC, PENDING_INVITE, active_trusted_relays}; use crate::{Profile, account_manager, db, crypto, commands}; +/// Set to true after a full foreground login+sync flow completes. +/// Prevents debug_hot_reload_sync from using partial state preloaded by standalone background sync. +static FULL_SESSION_INITIALIZED: AtomicBool = AtomicBool::new(false); + // ============================================================================ // Types // ============================================================================ @@ -54,10 +59,14 @@ pub async fn debug_hot_reload_sync() -> Result { // Get the full state let state = STATE.lock().await; - // Verify we have meaningful state (not just an empty initialized state) + // Verify we have state from a full app session, not partial state from + // standalone background sync (which only preloads MLS groups + notification profiles). if state.profiles.is_empty() && state.chats.is_empty() { return Err("Backend state is empty - perform normal login".to_string()); } + if !FULL_SESSION_INITIALIZED.load(std::sync::atomic::Ordering::Acquire) { + return Err("State is from background sync, not a full session - perform normal login".to_string()); + } // Return the full state for the frontend to hydrate println!("[Debug Hot-Reload] Sending cached state to frontend ({} profiles, {} chats)", @@ -158,6 +167,7 @@ pub async fn login(mut import_key: String) -> Result { } } + FULL_SESSION_INITIALIZED.store(true, std::sync::atomic::Ordering::Release); Ok(LoginResult { public: npub }) } @@ -277,6 +287,7 @@ pub async fn create_account() -> Result { // This prevents creating "dead accounts" if user quits before setting a PIN account_manager::set_pending_account(npub.clone())?; + FULL_SESSION_INITIALIZED.store(true, std::sync::atomic::Ordering::Release); Ok(LoginResult { public: npub }) } @@ -446,8 +457,32 @@ pub async fn decrypt(ciphertext: String, password: Option) -> Result) -> Result { - // If already logged in, just return the npub - if let Some(_client) = NOSTR_CLIENT.get() { + // If already logged in (e.g. standalone background sync set NOSTR_CLIENT before + // the Activity created), clear stale state so the foreground rebuilds everything fresh. + // The client's signer (GuardedSigner) and MY_SECRET_KEY are still valid. + if let Some(client) = NOSTR_CLIENT.get() { + // Remove background sync's relay(s) — they may be disconnected and incomplete. + // The frontend's connect() call will add all proper relays and reconnect. + let stale_relays: Vec = client.relays().await + .keys().map(|u| u.to_string()).collect(); + for url in &stale_relays { + let _ = client.remove_relay(url.as_str()).await; + } + + // Clear STATE — standalone sync only preloads MLS groups + notification profiles, + // which is a partial subset.
