@zula-editor reported on issue #15 that the Check-for-updates button
was returning HTTP 403 on their ISP — classic GitHub
unauthenticated-API rate limit (60/hour per IP) on a shared NAT IP.
They also asked for the update to actually be downloadable from the
app, not just a page link.
Both addressed:
=== Route update check through our own proxy when running ===
New mhrv_rs::update_check::Route enum:
- Direct: straight rustls to api.github.com (existing behavior)
- Proxy { host, port }: HTTP CONNECT through our local HTTP proxy
listener → MITM → Apps Script → api.github.com.
When the proxy is running, the UI automatically picks Proxy. From
GitHub's POV the request now comes from Apps Script's IP range (a
Google datacenter) — completely different rate-limit bucket from the
user's ISP IP, AND works even if GitHub is blocked on their network.
Routing over proxy means the MITM leaf for api.github.com has to be
trusted in the update_check's TLS config. build_root_store() now
conditionally adds our own CA cert from data_dir::ca_cert_path() to
the webpki roots when Route::Proxy is in use. Direct path is
unchanged.
=== Download button ===
The UpdateCheck::UpdateAvailable variant now carries an optional
ReleaseAsset { name, download_url, size_bytes } picked by
pick_asset_for_platform() from the GitHub API's assets[] array.
Preference list per (OS, arch):
- macOS arm64 → mhrv-rs-macos-arm64-app.zip, else tar.gz
- macOS amd64 → mhrv-rs-macos-amd64-app.zip, else tar.gz
- Windows → mhrv-rs-windows-amd64.zip
- Linux aarch64 → mhrv-rs-linux-arm64.tar.gz
- Linux armv7 → mhrv-rs-raspbian-armhf.tar.gz
- Linux x86_64 → mhrv-rs-linux-amd64.tar.gz
UI: when an update is available AND we have an asset, the transient
status line grows an accent-blue 'Download X.Y MB' button. Clicking
fires Cmd::DownloadUpdate, which pipes the asset through the same
Route (proxy if running, direct otherwise), writes it to
UserDirs::download_dir() (~/Downloads on most systems), and shows a
'show in folder' button that opens Finder / Explorer / xdg-open on
the containing directory.
Three new unit tests for asset-picking. The gated live test now
takes a Route argument (Direct) so it keeps working across the API
shape change. 49 tests pass.
Also refreshed in-repo releases/ archives to v0.9.1 alongside.
User @barzamini pointed out an optimization from the Python community
(originally from seramo_ir): X/Twitter GraphQL URLs look like
https://x.com/i/api/graphql/{hash}/{op}?variables=...&features=...&fieldToggles=...
The features and fieldToggles params change across sessions and even
within a session, busting our 50 MB response cache on every request to
the same logical query. Stripping everything after 'variables=' lets
identical logical queries collapse into one cache entry, dramatically
reducing quota usage when browsing Twitter through the relay.
Implementation:
- src/domain_fronter.rs: new normalize_x_graphql_url() helper. Matches
exactly the Python patch's pattern (host == 'x.com', path starts
with /i/api/graphql/, query starts with variables=). Truncates at
the first '&' past the '?'. Applied at the top of relay() so the
normalized URL feeds BOTH the cache key AND the request sent to
Apps Script — so we save on Apps Script quota too, not just on
return-trip bytes.
- src/config.rs: new opt-in normalize_x_graphql bool (default false).
Off by default because strict X endpoints may reject trimmed requests;
user should flip it on and watch for regressions.
- src/bin/ui.rs: checkbox in the Advanced section,
'Normalize X/Twitter GraphQL URLs', with tooltip explaining the
trade-off and crediting the source.
- Four new unit tests in domain_fronter::tests covering: the happy
path trim, non-x.com hosts pass through unchanged, non-graphql x.com
paths pass through unchanged, and idempotency. 48 tests total, all
green.

=== UI redesign (zero new deps, same binary size) ===
Entire App::update() rewritten around three ideas:
1. Section cards. Form rows are grouped inside rounded frames with
faint fills and small-caps headings:
- 'Apps Script relay' — Deployment IDs (textarea) + Auth key
- 'Network' — Google IP (+inline scan button), Front
domain, Listen host, HTTP+SOCKS5 ports
on one row, SNI pool button
- Collapsing 'Advanced' — upstream SOCKS5, parallel dispatch,
log level, verify SSL, show auth key.
Closed by default — most users never
touch these.
2. Clearer action hierarchy. Primary buttons are accent-filled and
larger:
- Start (green filled, ▶ glyph, 120x32)
- Stop (red filled, ■ glyph, 120x32)
- Save config (blue accent filled, path shown inline after →)
- SNI pool (blue accent filled, inside Network section)
- Test relay (neutral, tall)
Secondary actions (Install CA / Check CA / Check for updates)
moved to their own compact row below, no longer competing.
3. Status + log clarity.
- Header version links to GitHub: → repo, →
the release tag page.
- Running/stopped status is now a pill-shaped colored chip at the
right end of the header (green fill + green dot when running,
red when stopped).
- Traffic stats in a 2-column layout inside the Traffic card —
7 metrics fit in 4 rows instead of a 7-row vertical strip.
- One compact transient status line above the log that auto-hides
after 10 seconds — replaces the previous stack of permanent
ca_trusted / test_msg / update_check labels that were pushing
the log panel off-screen.
- Log panel now has its own bordered frame (darker fill), a
'[x] show' checkbox that hides it entirely when off, a 'save…'
button that writes the current log buffer to a timestamped
log-YYYYMMDD-HHMMSS.txt in the user-data dir, and a 'clear'
button. Empty state shows a muted placeholder instead of
silent void.
All helper functions (section, primary_button, form_row) live at the
top of ui.rs as small local helpers — no new modules, no new
dependencies.
=== Stricter end-to-end test (test_cmd.rs) ===
Previous test passed on any HTTP 200 status regardless of body.
After a user pointed out that the test reported PASS even after
they deleted their Apps Script deployment, updated the pass criteria:
1. Status must contain '200 OK'.
2. Body must parse as JSON.
3. JSON must have an 'ip' field with a valid IPv4 or IPv6.
Anything else → SUSPECT (returns false), with a specific log message
like 'HTML returned instead of JSON. The Apps Script deployment may
be deleted, not published to Anyone, or requires sign-in.'
Also now emits tracing::info!/warn!/error! alongside println!, so
the verdict + detail show up in the UI's Recent log panel instead
of disappearing to a stdout nobody sees.
One new unit test: looks_like_ip() accepts v4+v6, rejects empty,
rejects malformed, rejects overflowed octets. 44 tests total, all
green.
Verified locally end-to-end — UI launches clean, form loads config
cleanly, Start/Stop/Save all fire correctly, Test relay produces
the new PASS/SUSPECT verdict with the tracing detail visible in
the log panel, Check-for-updates hits GitHub and resolves with the
compact auto-hiding status line.
=== PR #14 follow-up: armhf build runs on Pi Bookworm/Bullseye ===
PR #14 (merged earlier) added arm-unknown-linux-gnueabihf to the
release matrix but pinned os=ubuntu-latest, which is 24.04 with GLIBC
2.39. Target armhf sysroot on 24.04 is Debian Trixie (GLIBC 2.39),
far too new for a Raspberry Pi 2/3 on Bookworm (2.36) or Bullseye
(2.31) — users would get 'GLIBC_2.39 not found' the same way the
Linux-amd64 issue #2 folks did before we pinned them to 22.04.
Fix: pin the armhf matrix entry to ubuntu-22.04, matching our other
linux-gnu targets. Binary will link against GLIBC 2.35 max, which
loads on Pi Bookworm and Bullseye. Also trimmed two trailing spaces.
Locally verified the cross-compile: rust:latest + gcc-arm-linux-
gnueabihf + proper CARGO_HOME config.toml produces a valid ARM 32-bit
ELF (2.9 MB, armhf EABI5).
=== Issue #15: 'Check for updates' button in the UI ===
New src/update_check.rs module. On the user's click (no polling):
1. Tcp-probes github.com:443 with a 5s budget. If unreachable, we
return Offline(reason) instead of a confusing 'update check
failed' — distinguishes 'you're offline' from 'GitHub API
misbehaved'.
2. HTTPS GET api.github.com/repos/.../releases/latest via the
tokio + rustls stack (same hand-rolled HTTP pattern as
domain_fronter — no new crate deps). Parses tag_name, strips
the v-prefix, loose-semver-compares to env!(CARGO_PKG_VERSION).
3. Returns one of four UpdateCheck variants: Offline / Error /
UpToDate / UpdateAvailable { release_url }.
New UI wiring (src/bin/ui.rs):
- Cmd::CheckUpdate enqueue variant
- UiState::last_update_check { InFlight, Done(result) }
- 'Check for updates' button next to the CA buttons
- Result displayed as a colored small-text line under the CA info:
green 'up to date', amber 'update available v0.8.5 → v0.8.6' with
a clickable release-page hyperlink, red for offline/error.
Verified end-to-end with a live github.com fetch (got a rate-limit
HTTP 403 from my IP because I've been hitting the API a lot, but
that's the expected Error() state — response classification was
correct). Three unit tests for is_newer() and a gated live test for
the full round-trip.
43 tests pass.
Thanks @hamed256 — armhf cross-compile verified locally, produces a valid ARM 32-bit ELF. Merging with a follow-up commit on main to pin the runner to ubuntu-22.04 (GLIBC 2.36 floor, same policy as our other linux-gnu targets) so it runs on Raspberry Pi users on Bookworm / Bullseye.
Two reasons to pin a copy in the repo:
1. Users on networks where raw.githubusercontent.com is intermittent
can still get the deploy-ready file via a repo ZIP / clone.
2. The Apps Script relay protocol between mhrv-rs and Code.gs is
informal — upstream changes can silently break us. Keeping a
snapshot lets future-us diff against what we tested against
when diagnosing protocol-drift bugs.
Fetched verbatim from:
https://raw.githubusercontent.com/masterking32/MasterHttpRelayVPN/refs/heads/python_testing/apps_script/Code.gs
Credit stays with @masterking32. The assets/apps_script/README.md
next to it calls out that we don't modify this file — users deploy
it as-is into their own Google Apps Script project.
Updated the Setup Guide link in both the English and Persian
sections so offline / restricted-network users have a fallback path.
User on issue #13 reported that even after installing the CA (and
seeing it in the Windows cert manager UI), our 'Check CA' button still
said 'NOT trusted'. Root cause: is_ca_trusted() on Windows was just
returning false unconditionally — Check-CA has never worked on Windows.
Fix: is_trusted_windows() now shells out to certutil:
certutil -user -store Root 'MasterHttpRelayVPN'
certutil -store Root 'MasterHttpRelayVPN'
Checks both the user store (where our install_windows puts it by
default) and the machine store (fallback path when user-store install
is blocked). Requires certutil to print the cert name in stdout AND
exit 0 — belt-and-suspenders against locales where certutil exits 0
even on an empty match.
Also made the Check-CA UI message point users at the CA file path
for cross-device install — the same user reported their Android
V2rayNG client getting cert errors on our MITM-signed TLS leaves,
which is the expected 'the phone doesn't trust our CA' scenario. The
message now calls out the ca.crt path explicitly, and notes the
Android 7+ user-CA restriction (Firefox Android works, Chrome and
most apps don't trust user-installed CAs regardless).
Not addressed (by design):
- Replacing our CA keypair with Python-generated PEM fails to parse
via rcgen. User tried this as a workaround before reporting. rcgen
expects PKCS#8 PEM; Python's cryptography commonly emits PKCS#1
('BEGIN RSA PRIVATE KEY'). Even if parsing worked, mixing an
external CA with our leaf-issuing code would break the key match.
Users should stick with our generated CA — that's the supported
flow. The Python cross-contamination experiment is expected to
fail; we don't document it as supported.
A user reported that after Save-config, closing the UI, and reopening,
every form field was blank — but the config.json on disk still had all
the right values.
The culprit in the UI was load_form()'s swallow-errors pattern:
let existing = if path.exists() {
Config::load(&path).ok() // .ok() threw away the error
} else { ... };
if let Some(c) = existing { /* populate form */ } else { /* defaults */ }
When Config::load returned an Err, .ok() silently converted to None,
the form went back to defaults, and the user had no signal at all
that the load had failed or WHY. On every platform I could test
(macOS / Linux) the round-trip works fine with a real round-trip test
added in config.rs (config::rt_tests::round_trip_all_current_fields
and round_trip_minimal_fields_only — both green). So whatever's
failing for this specific reporter is environment-specific (weird
filesystem encoding, partial write, different field shape from an
older version, … TBD). Without visibility we can't diagnose it.
Changes:
1. load_form() now returns (FormState, Option<String>). The String
is a user-facing error message (with the full path + the
underlying parse/validate reason) when Config::load fails on an
existing file.
2. main() plumbs that error into App's initial toast, which sticks
for 30 seconds (vs the normal 5 for regular toasts) so users who
only open the UI briefly still see it.
3. Added tracing::info! in load_form for the success path too —
the Recent log panel now always shows either 'config: loaded OK
from <path>' or 'Config at <path> failed to load: <reason>' on
startup, regardless of toast timing.
4. Added two regression-guard tests in config.rs covering the
full-fields and minimal-fields save shapes the UI emits.
Next time a user reports this: they'll have the exact error in the
toast + the Recent log panel, and we can fix the actual bug instead
of shooting blind.
Two reported issues:
1. Log level in the form had no visible effect — trace produced the
same panel output as warn.
2. upstream_socks5 was reported as never being attempted.
(1) was because the UI binary never installed a tracing subscriber.
Every tracing::info!/debug!/trace! from the proxy was discarded; only
the handful of manual push_log() calls for start/stop/test reached
the 'Recent log' panel. Swapping the log level in the combo-box just
rewrote the config field — nothing consumed it.
Fix: install_ui_tracing() at startup registers a tracing_subscriber
fmt layer with a custom MakeWriter that mirrors each formatted event
line into shared.state.log. Respects RUST_LOG, defaults to 'info'
with hyper pinned to warn so the panel isn't swamped by low-level
HTTP chatter. Now the log level switch actually filters panel
output, and routing decisions show up live.
(2) is a documentation / visibility issue more than a bug. Our
upstream_socks5 routing is intentionally scoped to raw-TCP traffic
(non-HTTP, non-TLS) — HTTPS goes through the Apps Script relay,
which is the whole reason mhrv-rs exists. But without working logs,
it looks like upstream_socks5 is dead code.
Fix: every branch of dispatch_tunnel now emits a tracing::info! that
says exactly which path the connection took and, where applicable,
whether upstream_socks5 was used:
dispatch api.telegram.org:443 -> raw-tcp (127.0.0.1:50529)
dispatch www.google.com:443 -> sni-rewrite tunnel (Google edge direct)
dispatch httpbin.org:443 -> MITM + Apps Script relay (TLS detected)
Combined with (1), users can now see in real time whether their
traffic is hitting upstream_socks5. If it says 'raw-tcp (direct)'
after they set the field, that's evidence of a real bug; if it
never reaches the raw-tcp branch at all, that's the documented
design (HTTPS → Apps Script).
Also per user request, updated README:
- Shields.io badges up top: latest release, total downloads, CI
status, license, stars.
- Short 'Heads up on authorship' note crediting Anthropic's Claude
for the bulk of the Rust port (with the human-on-every-commit
caveat). English and Persian mirrors both have it.
All 37 unit tests pass.
After v0.8.1 fixed the leaf cert extensions, users reported "still
broken" — specifically Firefox showing:
"Software is Preventing Firefox From Safely Connecting to This Site.
drive.google.com ... This issue is caused by MasterHttpRelayVPN"
for HSTS-preloaded sites. That error is Firefox's "MITM detected AND
issuing CA isn't in my trust store" path combined with HSTS blocking
the normal override button — so users were stuck with no workaround.
Real root cause of the "still broken" reports: the CA was making it
into the OS trust store (Windows cert store / update-ca-certificates
on Linux) but NOT into the browser-specific trust stores that
Firefox and Chrome use on every OS.
Three additions:
1. Firefox: .
For every Firefox profile we find, we now write this pref to the
profile's user.js. It tells Firefox to trust the OS CA store, so
our already-successful system-level install automatically covers
Firefox on next startup. Critical on Windows (NSS certutil isn't
on PATH there, so the certutil-based Firefox install never
worked). Idempotent — checks for existing pref before writing
and leaves a non-matching user value alone.
2. Chrome/Chromium on Linux: install into ~/.pki/nssdb.
Linux Chrome uses its own shared NSS DB, independent of both the
OS store (populated by update-ca-certificates) AND Firefox's
per-profile NSS. Without this, users installed the CA via
run.sh, Chrome still refused every HTTPS site, and they spiraled
trying to re-install the CA. We now also initialize that DB
with if it doesn't exist yet.
3. Refactored the NSS-install path so Firefox and Chrome share a
single install_nss_in_dir() helper. Renamed the top-level entry
from install_firefox_nss to install_nss_stores to match scope.
Locally verified the cert itself is fine — openssl x509 -text shows
Version 3, SAN, KeyUsage (critical), ExtendedKeyUsage, and
passes. So the leaf is correct;
what was failing was the trust-chain validation inside the specific
browser because our CA wasn't in THAT browser's trust DB.
Upgrade path: download v0.8.2 and run the launcher or
`./mhrv-rs --install-cert`. Restart Firefox/Chrome after install —
Firefox needs the restart to re-read user.js.
Multiple users reported the same thing (issue #11): they trusted the
CA, then re-installed it, then deleted and re-generated it, and still
every HTTPS site through the proxy failed in the browser. The python
version of the same project doesn't have the issue.
Root cause: rcgen's CertificateParams::default() produces a
minimum-viable x509 cert that does NOT carry:
- ExtendedKeyUsage extension with id-kp-serverAuth
- KeyUsage extension with digitalSignature + keyEncipherment
Modern Chrome / Firefox / Edge / Safari all reject TLS server leaves
without those. The CA trust bit didn't matter — the browser's chain
validator rejected the leaf itself with NET::ERR_CERT_INVALID before
ever consulting the trust store. So 'reinstall the CA' was powerless
to help.
Fix in src/mitm.rs::issue_leaf:
- Set params.extended_key_usages = [ServerAuth].
- Set params.key_usages = [DigitalSignature, KeyEncipherment].
- Backdate not_before by 5 min to absorb clock skew between the
MITM process and a slightly-fast client clock. Same fix in the
CA's own not_before.
Also added src/mitm.rs::tests::leaf_has_serverauth_eku_and_key_usage
as a permanent regression guard — it parses the DER with x509-parser
and asserts the three extensions are present. Added x509-parser to
dev-dependencies (already in the tree transitively via rcgen).
Upgrade path for users affected by #11: download v0.8.1, run it. No
CA reinstall required — the CA cert itself was fine, only the per-
site leaves were broken.
Verified end-to-end locally:
curl --cacert <ca.crt> -x http://127.0.0.1:... https://httpbin.org/ip
curl --cacert <ca.crt> -x socks5h://127.0.0.1:... https://httpbin.org/ip
Both return JSON without cert errors, through the Apps Script relay
path. 37 unit tests pass.
Placing a new table header before eframe silently scoped it into the
unix-only target table, so Windows builds lost the dependency entirely:
error[E0432]: unresolved import `eframe`
use of unresolved module or unlinked crate `eframe`
(Builds green on Mac/Linux because those hit cfg(unix) == true. Windows
was the only casualty.)
Moved the [target.'cfg(unix)'.dependencies] block to the end of
Cargo.toml, after the optional eframe line, so the main [dependencies]
table stays intact for all targets. Added a comment so this foot-gun
can't return.
Three user-reported fixes / features in one release.
=== PR #9 — dynamic Google IP discovery (@v4g4b0nd-0x76) ===
Already merged in the previous commit. Opt-in via 'fetch_ips_from_api'
in config. Pulls goog.json from www.gstatic.com, maps it against
resolved IPs of well-known Google domains, samples from matching
CIDRs, and validates each candidate with gws / x-google / alt-svc
response-header checks. Graceful fallback to the static list if the
fetch fails or nothing passes validation. Default is off so existing
users are unaffected. Closes#10.
=== Issue #8 — OpenWRT: 'accept: No file descriptors available' ===
OpenWRT routers ship a very low RLIMIT_NOFILE (often 1024, sometimes
256 on constrained devices). A browser's burst of ~30 parallel sub-
resource requests can fill the limit within seconds, after which
accept(2) returns EMFILE and the proxy is effectively dead.
Two-fold fix:
1. New assets/openwrt/mhrv-rs.init now sets procd limits nofile=
"16384 16384" on the service. procd raises the per-process fd
limit before the binary even starts.
2. New src/rlimit.rs best-effort-raises RLIMIT_NOFILE in the binary
itself (Unix only, no new runtime deps — libc is already
transitively present via tokio). Targets 16384 soft, capped to
whatever hard limit the kernel already allows the user (so it
doesn't need root).
Both layers mean the fix applies whether the user runs via
/etc/init.d/mhrv-rs start (procd limits kick in)
or
./mhrv-rs --config ... (in-binary bump kicks in)
or any other invocation path.
Closes#8.
=== Issue #7 — Windows UI crashes silently ===
User report: on Win 11, run.bat prints 'Starting mhrv-rs UI...' and
exits clean, but no UI window ever appears. Root cause: the old
run.bat used 'start "" "mhrv-rs-ui.exe"' which returns
immediately — if the UI binary dies at launch time (missing GPU
driver, RDP without GL accel, AV blocking, …), the crash is invisible
because start already disowned the child.
Fix: run the UI in-place (not via 'start'), so its stderr and exit
code land in the run.bat cmd window. On non-zero exit print a helpful
checklist of common Windows launch failures and pause so the user can
screenshot the output for an issue report.
This doesn't fix the underlying crash for affected users, but it
turns a ghost-crash bug into a self-diagnosing one so the next report
includes actionable info. Closes-via-diag #7.
=== Fixes folded into the PR #9 merge ===
- src/scan_ips.rs: rand::thread_rng() held across an .await tripped
the Send bound on the async fn. Scoped the rng in a block so it
drops before the subsequent awaits.
- src/scan_ips.rs: defend /0 and /32 CIDRs in cidr_to_ips and
ip_in_cidr against 1u32 << 32 shift panic.
All 36 unit tests pass.
Thanks @v4g4b0nd-0x76 for the feature. Two small fixes folded in on
the merge so master still builds + doesn't hit sharp edges:
- src/scan_ips.rs: rand::thread_rng() held across an .await tripped
the Send bound on the async fn (ThreadRng isn't Send). Scoped the
rng in a block so it drops before subsequent awaits.
- src/scan_ips.rs: guard /0 and /32 CIDRs in cidr_to_ips and
ip_in_cidr against the 1u32 << 32 shift panic (debug mode). goog.json
is unlikely to contain either but defensive.
Behavior unchanged otherwise:
- fetch_ips_from_api=false (default): identical to previous static
scan-ips behavior.
- fetch_ips_from_api=true: fetches goog.json from www.gstatic.com,
resolves famous Google domain IPs, prioritises matching CIDRs,
samples up to max_ips_to_scan candidates, validates with gws/
x-google-/alt-svc headers. If the fetch fails, falls back to the
static list cleanly — verified locally.
Closes#10.
Two user complaints:
- English words mixed inline in the Persian section were breaking the
RTL text flow, making paragraphs hard to read.
- Language was too technical for non-developer users.
Fixes:
1. Every English / technical term is now wrapped in backticks
(`Apps Script`, `MITM`, `SOCKS5`, `Deployment ID`, …). GitHub
renders these as monospace LTR islands, which the browser's
bidirectional text algorithm treats as embedded strong-LTR runs
and doesn't let them flip the surrounding RTL paragraph direction.
2. Rewrote most paragraphs as shorter, plainer Persian sentences.
Replaced jargon (run-time, on-the-fly, rewrite, trust store…)
with everyday wording.
3. Converted dense prose into tables where it helped (download
table by OS, config fields table, per-OS CA install table).
4. Added a 5-step walkthrough (script deploy → download → first
run → config in UI → browser setup) that a non-technical user
can follow top-to-bottom.
5. New 'How do I know it's working?' quick verification section.
6. New big FAQ at the bottom — covers the questions that actually
come up: certificate install safety, how to remove the cert,
how many Deployment IDs to use, YouTube / ChatGPT caveats,
the GLIBC 2.39 issue, and CLI usage for power users.
7. Telegram pairing section reworded — explains the WHY first
(Apps Script can't speak MTProto), then the one-line fix.
8. SNI pool editor flow written as numbered steps mirroring the
actual UI buttons the user clicks.
English section unchanged.
Verified: the linux-amd64 binary's highest GLIBC symbol is now 2.34
(was 2.39 in v0.7.0 and earlier), so it runs on Ubuntu 22.04 / Mint 21
/ Debian 12 and anything newer.
Two user-reported issues.
=== GLIBC too new (reported via twitter) ===
Our linux-amd64 and linux-arm64 gnu builds were compiled on
ubuntu-latest (24.04, GLIBC 2.39), which means the resulting binaries
refuse to load on anything older:
./mhrv-rs: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.39'
not found (required by ./mhrv-rs)
Users on Ubuntu 22.04 / Mint 21 (GLIBC 2.35) — the typical user in Iran
where this project's target audience lives, and where they can't
dist-upgrade because they're behind exactly the kind of network
restriction this tool exists to bypass — could not run the gnu builds
at all.
Fix: pin the linux-gnu matrix entries to ubuntu-22.04 runners. GLIBC
2.35 is now the minimum; binaries load on Ubuntu 22.04, Mint 21,
Debian 12, Fedora 36+, RHEL 9+ and everything newer.
Users on older distros (Ubuntu 20.04, CentOS 7) can still use the
static musl builds (mhrv-rs-linux-musl-amd64.tar.gz et al.) which
have no GLIBC dependency at all.
=== Short-screen laptops — main window content clipped (PR #6) ===
Co-authored fix from @v4g4b0nd-0x76 in PR #6 (manually applied to
avoid pulling in 400 lines of unrelated cargo-fmt churn):
- Wrap the CentralPanel body in ScrollArea::vertical()
.auto_shrink([false; 2]) so everything stays reachable on short
screens.
- Lower the min_inner_size from [420, 540] to [420, 400] so laptops
with ~13" screens at default scaling can shrink the window without
clipping UI elements.
Closes#6.
Co-authored-by: v4g4b0nd-0x76 <v4g4b0nd-0x76@users.noreply.github.com>
Thanks @v4g4b0nd-0x76 — proper listener teardown on Stop is exactly what was needed. The 2-second grace window + force-abort fallback is a clean pattern.
New feature — users can now edit exactly which SNI names are rotated
through the outbound Google-edge tunnel, and probe each one's
reachability. Useful when an ISP selectively blocks individual Google
subdomains (e.g. mail.google.com in Iran at various times).
=== Data model ===
Config gains an optional 'sni_hosts' field:
"sni_hosts": ["www.google.com", "drive.google.com"]
Precedence in domain_fronter::build_sni_pool_for():
1. If sni_hosts is set & non-empty, use that list verbatim.
2. Else, if front_domain is one of the default Google-edge names,
auto-expand to {www, mail, drive, docs, calendar}.google.com.
3. Else, use just [front_domain].
Empty / all-disabled list saves as None so the backend falls back to
the defaults instead of having zero names to rotate through.
=== New scan_sni module ===
probe_one(ip, sni) / probe_all(ip, snis) does, for each candidate:
1. DNS lookup on the SNI (catches typos / non-existent names — Google
GFE returns a valid wildcard cert for ANY *.google.com, so the
TLS handshake alone can't tell apart a real name from gibberish).
2. TCP connect to google_ip:443 (3s timeout).
3. TLS handshake with the candidate SNI (3s timeout). RST mid-
handshake signals DPI block.
4. Small HTTP HEAD over the tunnel to confirm it's still speaking
HTTP (catches weird misroutes).
Returns ProbeResult { latency_ms, error } per candidate.
=== New 'test-sni' CLI subcommand ===
$ mhrv-rs test-sni
Probing 5 SNI candidates against google_ip=216.239.38.120 ...
SNI LATENCY STATUS
www.google.com 142 ms ok
drive.google.com 138 ms ok
mail.google.com - handshake RST (SNI may be blocked)
...
Working: 3 / 5
Exit 0 if >=1 passed, non-zero otherwise. Uses the same probe logic
the UI uses.
=== UI editor ===
New 'SNI pool... (active/total)' button in the main form, styled with
a solid blue fill + white text so it's clearly actionable. Opens a
floating egui::Window (resizable, movable, closable) with:
- Action bar: 'Test all' | 'Keep working only' | 'Enable all' |
'Clear status' | 'Reset to defaults'
- Scrollable list of rows, each: checkbox, monospaced name editor
(230px), status cell (150px, 'ok 142 ms' green / 'fail <reason>'
red / 'testing...' gray / 'untested' gray), per-row 'Test' and
'remove' buttons
- Bottom: text input + '+ Add' that auto-probes the newly added name
immediately (instead of leaving it silently 'untested')
All rendered with ASCII status text instead of unicode check/cross
glyphs, since egui's default font doesn't ship them on some hosts
and they rendered as a missing-glyph box.
Changes only commit when the user hits Save config in the main window;
probe state is held in UiState::sni_probe so it survives opening and
closing the editor.
=== README ===
English + Persian 'SNI pool editor' sections with the two workflows
(UI button + 'sni_hosts' config field), plus a 'test-sni' line added
to the Diagnostics section. Feature list updated.
v0.6.0's release CI was cancelled before it could produce artifacts.
This is a clean re-cut that also fixes a user-reported bug on OpenWRT.
=== OpenWRT CA install fix ===
User on issue #2 reported that --install-cert fails on an OpenWRT
router with 'install failed on this platform'. Two problems:
1. Misclassification. The old distro detector did a substring-match
over all of /etc/os-release, and OpenWRT's file contains lines
like OPENWRT_DEVICE_ARCH=x86_64 and OPENWRT_ARCH=x86_64 — which
contain the substring 'arch' — so we classified OpenWRT as Arch
Linux and tried to install into /etc/ca-certificates/trust-source/
anchors/ (which doesn't exist there) and then run 'trust' (also
missing). Predictable failure.
2. Even with correct classification, OpenWRT doesn't need the CA on
the router itself. LAN clients are the ones terminating TLS through
mhrv-rs's MITM; they're the ones that need to trust our root. The
router is just forwarding packets. So emitting an error for the
no-op case is misleading.
Fixes:
- Detect OpenWRT explicitly (/etc/openwrt_release marker file +
ID=openwrt in os-release).
- Rewrite the fallback os-release parser to look at ID / ID_LIKE
token-wise instead of substring-matching the whole file. Added
support for raspbian / rocky / almalinux / endeavouros while we're
there.
- For OpenWRT: install_linux returns Ok() with a clear message
explaining that the CA needs to be installed on LAN clients, not
on the router. No-op success instead of confusing error.
- For unknown distros: the error message now points at the CA file
path and the two most common anchor dirs so the user can install
manually.
- Extracted classify_os_release(&str) as a pure function and added
8 unit tests, including a regression guard with a real OpenWRT 23.05
os-release file so this specific substring-match bug can't return.
=== v0.6.0 perf pack (same as what cancelled CI was meant to ship) ===
- Connection pool pre-warm on startup (skip handshake on first request)
- Per-connection SNI rotation across known Google-edge subdomains
- Expanded SNI-rewrite suffix list (gstatic, googleusercontent,
googleapis, ggpht, ytimg, blogspot, blogger)
- Per-site stats tracker + UI drill-down table
- Optional parallel script-ID dispatch (config field parallel_relay)
- TCP_NODELAY audit + fix on SNI-rewrite outbound
All 36 unit tests pass.
Closes-via-fix #2 follow-up.
Tier-1 perf changes from the brainstorm, all on by default except where
they change semantics (parallel_relay is opt-in).
Connection pool pre-warm (domain_fronter.rs):
On startup, open 3 TLS connections to Google edge in parallel and
park them in the pool. First user request skips the ~300-500 ms
handshake cost. Best-effort: warm failures are logged at debug and
ignored. Triggered from ProxyServer::run() in a fire-and-forget
tokio spawn.
SNI rotation (domain_fronter.rs):
Replace the single sni_host String with a Vec<String> plus an atomic
round-robin index. When front_domain is one of the known Google-edge
subdomains, build_sni_pool() expands it to include the other four
(www/mail/drive/docs/calendar.google.com), so outbound TLS connection
counts get spread across names instead of concentrating on one. Custom
front_domain values are preserved as the single entry (we can't verify
siblings of a non-Google edge).
Expanded SNI-rewrite suffix list (proxy_server.rs):
Added gstatic.com, googleusercontent.com, googleapis.com, ggpht.com,
ytimg.com, blogspot.com, blogger.com to the list of domains routed
directly via the Google-edge tunnel instead of through the Apps Script
relay. Bigger bypass = less UA-locking, less quota burn on static CDN
content.
Per-site stats (domain_fronter.rs + ui.rs):
New HostStat struct {requests, cache_hits, bytes, total_latency_ns}
tracked per URL host. Records on both cache hits and relay calls, not
on SNI-rewrite bypasses (those never touch the fronter). UI renders
a collapsible table under the existing stats grid with the top 60
hosts sorted by request count, showing req count, cache hit %, bytes,
avg latency ms.
Parallel script-ID dispatch (config.rs, domain_fronter.rs, ui.rs):
New config field parallel_relay: u8 (default 0 = off). When >= 2 and
there are enough non-blacklisted IDs, do_relay_with_retry fans out
the request to N script instances concurrently via futures_util's
select_ok, returns first success, cancels the rest. Kills long-tail
latency when one Apps Script instance happens to be slow, at the
cost of N× quota per request. UI exposes it as a DragValue 0-8.
TCP_NODELAY audit (proxy_server.rs):
Added the missing set_nodelay(true) call on the SNI-rewrite outbound
TCP stream. All six TcpStream::connect sites in the user traffic path
now disable Nagle.
Expanded feature list in README, added futures-util dep, added unit
tests for extract_host and build_sni_pool.
Verified end-to-end locally:
- Pool pre-warm log line appears on startup: 'pool pre-warmed with 3
connection(s)'.
- Static asset hit 3x: first = 2.2s (Apps Script), 2-3 = 6ms (cache).
- youtube.com / google.com: SNI-rewrite tunnel (unchanged).
- All 28 unit tests pass.
Deferred (not in this release, each needs its own cycle):
- uTLS / Chrome fingerprint mimicry (TLS stack swap)
- QUIC/HTTP3 transport (new transport)
- ETag / If-None-Match revalidation (needs cache schema change)
- JSON envelope gzip on request (needs Code.gs change)
- Firebase Cloud Functions as alt backend (new architecture)
- MSS clamp / TCP Fast Open (platform-specific, marginal)
The messense/rust-musl-cross images expect to run as root so cargo can
write to /root/.cargo. Overriding the container user to match the host
UID broke cargo's registry cache with 'Permission denied' before a
single file compiled. Drop the flag and chown the target/ tree after
the build instead.
A user on OpenWRT x86_64 reported the linux release doesn't run there —
root cause was glibc vs musl mismatch (our gnu binary was looking for a
dynamic linker that doesn't exist on router userlands). Add two musl
targets that produce fully static PIE binaries:
- x86_64-unknown-linux-musl -> mhrv-rs-linux-musl-amd64.tar.gz
- aarch64-unknown-linux-musl -> mhrv-rs-linux-musl-arm64.tar.gz
CI uses the messense/rust-musl-cross docker images (better-maintained
than cargo-zigbuild with a pinned zig, which has version regressions
on the ar wrapper between 0.13 and 0.16).
Locally verified:
- both archs cross-compile green in docker
- resulting x86_64 binary (3.3 MB) runs in an alpine:latest container,
--version / --help work, no dynamic lib requirements
The musl archive skips the UI (routers are headless) and swaps run.sh
for a procd init script (assets/openwrt/mhrv-rs.init) expecting the
binary at /usr/bin/mhrv-rs and config at /etc/mhrv-rs/config.json.
Side effect: switched tokio-rustls to default-features=false + ring
(was pulling aws-lc-rs transitively, which can't easily cross-compile
for musl). The main crate already uses ring explicitly, so no runtime
behavior change.
README gets a 'Running on OpenWRT (or any musl distro)' section in
both English and Persian with scp + procd enable/start recipe.
Closes#2.
The Apps Script relay is HTTP-only, and the SNI-rewrite tunnel only
works for Google-hosted domains — so MTProto / IMAP / SSH / anything
else used to drop to a direct-TCP passthrough, which provides zero
circumvention. Users behind a DPI that blocks Telegram saw constant
disconnect/reconnect loops because the raw TCP ran right into the
block.
Fix: add an optional 'upstream_socks5' config field. When set, the
raw-TCP fallback chains the flow into that SOCKS5 proxy (typically a
local xray / v2ray / sing-box with a VLESS / Trojan / Shadowsocks
outbound to your own VPS) instead of connecting directly. The whole
rest of the pipeline is unchanged:
- HTTP / HTTPS still MITMs and relays via Apps Script
- SNI-rewrite suffixes (google.com, youtube.com, …) still hit the
direct Google-edge tunnel (so YouTube stays fast)
- Only the raw-TCP bucket (Telegram MTProto, SSH, IMAP, …) gets the
new upstream chain
Changes:
- config.rs: add Option<String> upstream_socks5 field
- proxy_server.rs: thread it through RewriteCtx; rewrite
plain_tcp_passthrough to call a new socks5_connect_via() helper
when configured, with graceful fallback to direct
- ui.rs: new 'Upstream SOCKS5' input with tooltip + placeholder,
ConfigWire round-trip
- README.md: new 'Pair with xray for Telegram' section (EN + FA)
with the architecture diagram and example config
Verified end-to-end in Docker: xray with the user's working VLESS
Reality config, mhrv-rs with upstream_socks5 pointing at it.
- HTTPS via mhrv-rs SOCKS5: origin = Google IP (Apps Script path) ✓
- Raw TCP to 3 Telegram DCs + api.telegram.org: all SOCKS5 rep=0, log
shows 'tcp via upstream-socks5 127.0.0.1:50529 -> …' ✓
- youtube.com / google.com: 'SNI-rewrite tunnel' (unchanged) ✓
- Real Telegram Desktop stayed connected cleanly (user-confirmed).
Follow-up to v0.4.3 — users asked for one-ID-per-line instead of
comma-separated, which is easier to edit in the UI. Field is now a
3-row textarea with a rolling hint underneath:
- 0 or 1 IDs: 'Tip: add more IDs for round-robin with auto-failover'
- 2+ IDs: 'N IDs — round-robin with auto-failover on quota'
The parser accepts both newlines and commas as separators, so existing
configs keep loading cleanly. Closes#1.
The backend already supported a comma-separated list of Apps Script IDs
with round-robin dispatch and automatic 10-minute sidelining on quota
errors (429 / 403 / 'quota' in body). But the UI label just said 'Apps
Script ID' (singular), so users didn't realize multiple IDs are
allowed.
- Rename the label to 'Apps Script ID(s)'
- Hover tooltip explaining comma-separated input and quota auto-failover
- Placeholder hint 'id1, id2, id3 …'
- Live count line under the field when 2+ IDs are entered
Requested by a user in Farsi: 'add the ability to set multiple script
IDs; switch to the next when one hits its limit'. The feature existed,
this just surfaces it.
Mirror of the GitHub Release assets for all platforms, committed into
releases/ so that users behind a network that blocks the Releases page
can still grab the binaries via 'Download ZIP' or 'git clone'. Same
pattern as the sni-spoofing-rust repo.
The PNG carried an eXIf chunk (image dimensions — no GPS/camera/author
data, but metadata nonetheless). Re-encoded keeping only image-critical
chunks (IHDR, sRGB, IDAT, IEND).
