Adds end-to-end UDP support: SOCKS5 client UDP ASSOCIATE → tunnel-mux
udp_open/udp_data ops → tunnel-node UDP sessions → real UDP to upstream.
QUIC/HTTP3, DNS, and STUN now traverse full mode without falling back to
TCP or leaking outside the tunnel.
Apps Script proxies the new ops opaquely through the existing batch
endpoint; CodeFull.gs only gets a doc-comment update.
Highlights:
- proxy_server.rs: SOCKS5 UDP ASSOCIATE handler with per-session task,
bounded uplink mpsc channel, adaptive empty-poll backoff (500 ms → 30 s),
source-IP validation against the control TCP peer, port-locking on
first valid datagram, and self-removal from the dispatch map on eof.
- tunnel_client.rs: UdpOpen / UdpData / close_session mux variants
alongside the existing TCP plumbing; pkts decoder helper.
- tunnel-node: UdpSessionInner with bounded VecDeque queue, drop-oldest
on overflow with queue_drops counter and warn-then-throttled logs,
last_active refreshed only on real activity (uplink send or upstream
recv — empty polls do not refresh), independent TCP/UDP drain in
handle_batch Phase 2, separate active-drain (150 ms) and retry
(250 ms) windows for UDP, idle long-poll (5 s).
- Tests: SOCKS5 UDP packet parser (IPv4/IPv6/DOMAIN round-trips,
truncation rejects, fragmented rejects), UDP queue overflow drop +
counter, regression test that batch with both UDP and TCP-data ops
still runs the TCP retry pass.
Docs: README + android.{md,fa.md} updated to reflect UDP availability
in full mode; tunnel-node/README documents the new ops.
The old version landed each release cycle with a different "step 5
says to open Security settings but the code now opens top-level
Settings" kind of drift. Swept the whole page and rebuilt it around
what the app actually does on v1.0.2:
* adds a table of contents at the top — the guide is now scan-first
* requirements moved into a table so the phone/SDK/quota constraints
are all visible at once
* Apps Script deploy step uses a table for the New-deployment form
fields (less prose to read)
* step 4 (SNI tester) explains each possible row outcome in a table,
with the concrete "tap Auto-detect" action for the common failure
* step 5 (MITM CA) now matches the v1.0.2 flow: top-level Settings
app + search "CA certificate", not a Security-settings deep-link.
Search is more portable across Pixel/Samsung/Xiaomi than naming
the menu path
* new "UI quick reference" table mapping each control to what it does
— helps users who skipped the setup prose
* Known limitations tightened: Cloudflare Turnstile loop explained
with the (IP, UA, JA3) binding table; IPv6 leak, UDP/QUIC,
per-script quota, and the Android-7+ user-CA opt-out all kept
* Troubleshooting is now a single table with symptom → cause → fix
columns, including the INSTALL_FAILED_UPDATE_INCOMPATIBLE one-time
note for the v1.0.1 → v1.0.2 upgrade path
* new "Collecting a useful log" section: one copy-pasteable
adb logcat command that captures the tags that matter
(MhrvVpnService, mhrv_rs, mhrv-crash, tun2proxy)
* removed the stub Persian section at the bottom — it said
"file an issue if you want a translation" which is noise;
re-adding only if someone actually asks

Three fixes + one behaviour change from v1.0.1 reports.
APK signature is now stable (release.jks committed)
----------------------------------------------------
v1.0.0 and v1.0.1 signed release APKs with Gradle's
auto-generated debug keystore, which is randomly generated per
machine and per CI runner. Result: every upgrade failed with
INSTALL_FAILED_UPDATE_INCOMPATIBLE and users had to uninstall
first. Unfixable without a stable key.
android/app/release.jks now holds that key, committed to the
repo with the password in plaintext in build.gradle.kts. This
is fine for a FOSS sideload project without a Play Store
identity — the trust model is "trust the source tree you
pulled from," not "trust the key we hold." Anyone forking and
shipping a rebranded build should generate their own key.
One-time cost: v1.0.1 → v1.0.2 STILL requires uninstall,
because we're switching signature keys. Every upgrade from
v1.0.2 onward is clean.
Stop no longer (sometimes) closes the app
-----------------------------------------
teardown() is reachable from three paths on two threads:
1. ACTION_STOP onStartCommand branch (mhrv-teardown worker)
2. onDestroy after stopSelf (main thread)
3. VpnService revocation out-of-band (main thread)
Running the full native cleanup sequence twice races the two
threads through Tun2proxy.stop() → fd.close() →
Native.stopProxy(handle) on state that's already been
nullified — SIGSEGV source, user-visible as "tap Stop, app
disappears."
New AtomicBoolean `tornDown` gates entry: first caller wins,
every subsequent caller logs "teardown: already done" and
returns. onDestroy also wraps the call in try/catch — crashing
out of onDestroy takes the whole process with it, which is
exactly the bug we're trying to fix. Smoke-tested on emulator:
teardown now logs
teardown: begin caller=mhrv-teardown
... clean sequence ...
teardown: done
onDestroy entered
teardown: already done, skipping (caller=main)
onDestroy done
with PID unchanged throughout.
CA install now routes to the Settings search
--------------------------------------------
Old flow: `Settings.ACTION_SECURITY_SETTINGS` deep-link, then
walk "Encryption & credentials → Install a certificate →
CA certificate". That path varies wildly between OEMs (Samsung
buries it under "Biometrics and security → Other security
settings"; Xiaomi under "Passwords & Security → Privacy"; Pixel
splits it between "More security settings" and "Privacy
controls" depending on Android version). Users got lost.
New flow: open the top-level Settings app
(`Settings.ACTION_SETTINGS`) and instruct the user to use the
Settings search bar to find "CA certificate". Search is
consistent across OEMs and Android versions; the menu paths
are not. Dialog, snackbar, and `docs/android.md` copy all
updated to match.
Version bump: 1.0.1 → 1.0.2 (versionCode 101 → 102).
releases/mhrv-rs-android-universal-v1.0.1.apk replaced with
the v1.0.2 build.

Version bump reflects the scope — a unified Rust core that now ships
for desktop (Linux/macOS/Windows) AND Android from the same crate.
Android changes:
- build.gradle.kts: ABI filters expanded to arm64-v8a + armeabi-v7a
+ x86_64 + x86. cargoBuild{Debug,Release} pass all four ABIs to
cargo-ndk in a single invocation. normalizeTun2proxySo() walks every
ABI dir now (was arm64-only).
- Release buildType signs with the debug keystore — no Play Store
target, so signature identity doesn't matter, installability does.
Gradle auto-provisions ~/.android/debug.keystore if absent, so CI
runners inherit this without extra setup.
- versionName 1.0.0, versionCode 100 (room to bump monotonically).
CI:
- release.yml gets a dedicated `android:` job that sets up JDK 17,
Android SDK/NDK 26, all four rust-android targets, installs
cargo-ndk, runs assembleRelease, and uploads a single universal APK
named `mhrv-rs-android-universal-v<version>.apk` into the same
`dist/` collected by the release job downstream.
- `release:` job now gates on `needs: [build, android]` so tagging
v1.0.0 triggers both build matrices before cutting the GitHub
release.
Docs:
- docs/android.md — full 10-step install walk-through: APK sideload,
Apps Script deployment (with "Advanced → Go to (unsafe) → Allow"
reality check), config paste, SNI reachability test, MITM CA
install with OEM-specific nav paths (Pixel / Samsung / Xiaomi),
Start, troubleshooting common failure modes. Also documents the
known limitations — Cloudflare Turnstile loops (inherent to the
Apps Script egress IP pool), UDP/QUIC not tunnelled, IPv6 leaks,
Apps Script daily quota — so users know what to expect before
trying it on a site that won't work.
- releases/README.md — APK row added to the English and Persian
tables, version bumped everywhere to v1.0.0.
- Top-level README — Android listed under Platforms with a link
to docs/android.md.
Release artifact:
- releases/mhrv-rs-android-universal-v1.0.0.apk — 38 MB universal
APK built locally from this tree. Installs + launches on API 24+.
The CI job will regenerate it on tag push; this is the copy
committed for users who can't reach GitHub Releases.
