Every process (CLI daemon, GUI, TUN helper) and every subsystem (tracing, the
core event logger, the helper IPC, panic hook) wrote its own file: ostp-cli.log
+ ostp-core.log + ostp-helper.log + ostp-crash.log — a pile per run. Now they
all funnel into a single ostp.log next to the exe.
- logging: LOG_FILE_NAME/log_file_path() as the one source of truth; init_tracing
gains a `truncate` arg. Truncation is gated twice: Windows-only (cfg!(windows))
AND daemon-only. One-shot commands (gk/check/init/-V/...) and the elevated TUN
helper pass truncate=false so they can never wipe a running daemon's log;
invocation_is_daemon() detects the daemon from argv. On Linux the server always
appends (history kept, OS-rotated) as requested.
- runner/helper manual writers + panic hook now target log_file_path(), so their
output lands in the same ostp.log instead of separate files.
run_client_core previously ran once: if the OSTP protocol connection, the
TUN device, or the local proxy listener ended for any reason (network
change stranding the socket/adapter on a dead interface, a transient
crash, a drop the inner Bridge-level "TunnelStopped" retry couldn't
recover from), the whole client returned/errored and just stayed down.
Wrapped the existing body (now run_client_once) in an outer supervising
loop: any non-shutdown-requested exit triggers a full clean restart —
fresh DNS resolution, fresh Bridge, fresh TUN/proxy — with backoff
(1/2/5/10/20/30s, resetting once a run has been stable for 60s). Only an
explicit shutdown request stops the loop. connection_state reports
"connecting" during the retry wait so the UI shows reconnecting, not
disconnected.
security / protocol:
- Derive a PER-KEY junk marker (obfuscation.rs, info byte 0x04) instead of the
global constant [0x88,0x1A,0x93,0x5D]. A fixed marker was a universal DPI
signature identifying ALL OSTP users at once — exactly what the HKDF version
gate avoids for the handshake. Server drops junk via a new DispatchOutcome::Junk
inside the existing key-trial loop (secrets already derived → zero extra cost);
client stamps its own key's marker.
- §E: configurable junk/fragmentation params (junk_pc / junk_ps / frag_chunk / frag_sleep).
GUI (desktop):
- Light theme + toggle, GUI version footer in Settings.
- Fix mouse-wheel scroll on Settings (flex child needed min-height: 0).
- Drop the false "process exclusions unsupported in TUN mode" warning — they DO
work (native_handler maps port->process via GetExtendedTcpTable).
release / infra:
- build.ps1: add -PreRelease (tag CURRENT version as v<ver>-beta.N, no bump, no
master commit); guard the panel build when ostp-control ships no source; bump
the real ostp-gui/package.json instead of the nonexistent ostp-control one.
- release.yml: mark hyphenated tags as GitHub pre-releases; don't hard-fail the
web-panel step when there is no source (use committed dist/).
- Versions aligned to 0.4.1; README license badge BSL 1.1 -> AGPL v3.

- Boxed HandshakeState in NoiseSession to reduce enum variant sizes
- Used is_ok() instead of let Ok(_) pattern
- Applied automatic clippy fixes for minor warnings
DPI/TSPU resistance:
- Handshake packets now padded with 32-128 random bytes (prevents size
fingerprinting — previously every handshake was exactly 52 bytes)
- Frame header reserved bytes randomized instead of always 0 (prevents
known-plaintext oracle inside encrypted payload)
- Padding jitter cap increased from 96 to 256 bytes for better traffic
pattern masking
GUI Windows app (tunnel/proxy not starting):
- CRITICAL: Added CREATE_NO_WINDOW flag to all reg.exe calls in sysproxy.rs.
In Tauri GUI context (no console window), Command::new('reg') was silently
failing because there was no attached console. This prevented the Windows
system proxy from being enabled.
- Added ProxyOverride bypass list (localhost;127.*;10.*;192.168.*;<local>)
to prevent proxy loop for local traffic
- Added comprehensive logging for all registry operations
- Set initial connection_state to 1 (connecting) instead of 0 — prevents
UI polling from immediately flipping back to 'disconnected' before the
handshake has a chance to begin
Code quality:
- Fixed log file paths: log_to_core_file() and log_to_file() now write next
to the executable instead of CWD. In GUI context, CWD could be
C:\Windows\System32, causing write failures or misplaced log files.
- Unified log prefix to [ostp] across all modules (was [OSTP Core],
[ostp-server], [ostp-client], [client], [bridge])
- Removed informal/casual phrasing from all user-visible messages
- Startup messages are clean and concise (mode, server, status)
- Error messages are actionable without being alarming
- Essential server logs (client connect/disconnect) always visible
- Essential client logs (connection status, errors) always visible
- TUN tunnel messages consistent across Windows and Linux
- Removed noisy eprintln from UDP reader hot path
- Status format: [ostp] Status: Connected (rtt=12.3ms)
Critical fixes (6):
- protocol.rs: in_flight_count() now counts only retransmittable Data frames,
not Ack/Nack control frames — eliminates false backpressure under load
- protocol.rs: NACK is now rate-limited to once per 30ms — prevents
retransmission storm during normal UDP jitter
- protocol.rs: zombie frames exceeding max_retries+4 are evicted each tick —
prevents unbounded memory growth and stale retransmits
- protocol.rs: Closing state now processes final in-flight packets instead
of silently dropping them — prevents data loss at session teardown
- server/lib.rs: stream_tx changed from bounded(10000) to unbounded_channel —
prevents TCP-reader collapse during Speedtest with 50+ streams
- bridge.rs: liveness timeout raised from 30s to 60s — prevents false
reconnect during heavy Speedtest load
Medium fixes (8):
- protocol.rs: ACK range truncation preserves cumulative range (index 0)
- bridge.rs: Ping now uses send_datagram() for correct TURN wrapping
- dispatcher.rs: replay_cache hard-capped at 100k entries (DoS protection)
- dispatcher.rs: old addr cleaned from addr_to_session on roaming
- server/lib.rs: TCP connect_target() now has 10s timeout
- config.rs: TURN section parsed during hot-reload
- proxy.rs: HTTP header parsing uses 512-byte chunks instead of 1-byte reads
- proxy.rs: stream_id wrap-around skips active IDs to prevent collision
- runner.rs: is_essential_log matches actual log strings from bridge.rs
Other:
- kex.rs: clearly marked as dead PQ stub (not used by protocol)
- README.md + README.ru.md: complete rewrite with architecture diagram
- docs/en/specification.md: updated ARQ section with all new semantics
