Brings the Linux GUI up to parity with Windows. Four things blocked it, each
independently sufficient:
- build.rs keyed the Windows-manifest step off cfg(windows), which in a build
script describes the HOST. Cross-compiling the helper from Windows to Linux
therefore took that branch and died with "Can only compile resource file
when target_env is gnu or msvc". Now keyed off CARGO_CFG_TARGET_OS, with
the cfg(windows) gate kept as a second check because winres is a host-
resolved build-dependency and simply does not exist on a Linux host.
- launch_as_admin was bail!("Windows only.") outside Windows. Implemented for
Linux via pkexec, polkit's front-end, which raises a graphical auth prompt;
sudo is unusable from a GUI with no terminal. Missing pkexec now names the
package to install instead of failing opaquely.
- The release workflow only built ostp-tun-helper in the Windows job, so the
Linux package shipped without it. It is now built and placed next to the
GUI binary, where find_helper_exe looks first.
- set_autostart/get_autostart were no-ops off Windows. Implemented via XDG
autostart (~/.config/autostart/ostp.desktop, honouring XDG_CONFIG_HOME),
the direct equivalent of the HKCU Run key.
The helper's own code needed no changes — it already compiled for Linux once
the build script stopped rejecting it. list_running_processes already had a
Linux branch.
The token file is created 0600 on Linux: /tmp is world-readable there, unlike
the Windows temp dir, and that token authorises control of the privileged
helper.
Not verified on a live Linux desktop from here — the Tauri backend cannot be
compiled for Linux on a Windows host (GTK dev libraries), so the cfg(linux)
paths are reviewed rather than built. CI compiles them.
The repo switched to AGPLv3 back on 2026-06-18 (commit 9ce9e6d), and
Cargo.toml/README have said AGPL-3.0 ever since — but that license-change
commit was never carried forward into the 0.4.x rebuild branch, so the
actual LICENSE file silently reverted to the pre-rebuild BSL 1.1 text
(with a "converts to MIT in 2030" clause that hasn't applied for months).
Restored the real AGPLv3 text from 9ce9e6d.
Also added the missing `license` field to a few crate manifests that
didn't declare one (ostp-gui/src-tauri, ostp-jni, ostp-tun-helper), and
dropped the Tauri template placeholder authors/description.
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.
Ported only the fixes that actually apply to the pre-refactor base
(the handshake fixes 6eb7b36/d65af35 fix bugs the 0.3.1 multi-server
refactor introduced into the new outbounds/ostp.rs; the base bridge.rs
already waits for the handshake response with retransmit + NAT64
fallback, so they are intentionally skipped).
- EMFILE (922cf0b): rlimit::increase_nofile_limit at CLI startup.
- Logs (1151726): UoT connect/disconnect → debug; rate-limit the
unauthorized-probe log to one line / ~30s so a junk/probe flood can't
spam the log (and a client running junk-over-UDP can't self-ban).
- Helper lifecycle + bypass routes (b6e78c1):
* ostp-tun-helper forces std::process::exit(0) after run_server so the
WinTun adapter and its metric-0 default route are reclaimed instead
of lingering as a zombie that breaks the next connect.
* windows_route: delete_routes_for_dest() purges stale /32s, dedupe
bypass IPs, and log add failures at warn!.
* windows: retry tun::create through the transient ERROR_INVALID_
PARAMETER window and widen the adapter-index lookup to ~15s.

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.
- Removed stale KeyExchange re-export from crypto/mod.rs (kex.rs
only exports HybridSharedSecret and HybridKex after stub refactor)
- Removed unused imports in ostp-server/lib.rs (AsyncWriteExt,
tcp::OwnedWriteHalf)
- Suppressed dead_code warning on HelperMsg::Log variant (IPC spec)
- Verified: cargo check passes with zero errors and zero warnings
