v0.5.0

Performance improvement due to packet sniffing backend changes.

On Linux, SYN/ACK sniffing for --fake-autottl now uses AF_PACKET RxRing instead of nftables-based filtering. Packets are read via mmap'd ring buffer with zero copy from kernel to userspace, replacing the extra nftables rules that were needed for SYN/ACK capture.

On Windows, packet handling is now multi-threaded with separate recv/send/sniff paths, while sniff thread is only spawned when --fake-autottl is actually enabled.

Other changes:

• Windows exits immediately on Ctrl-C instead of waiting for cleanup.
• Logging defers local_time() until the log level check passes.
• infer_hops now correctly uses 128 (was 126).
• Various internal refactoring for consistency.
• Windows: service_install.bat no longer enables fake options by default. Add --fake-autottl to ARGS manually if needed.

2. Double-click dpibreak.exe to run, or start_fake.bat for fake mode.
3. To run automatically on boot, run service_install.bat as administrator.

v0.4.3

Upgrading from v0.4.0/v0.4.1: Stop any running dpibreak instance (sudo pkill dpibreak) before upgrading. The PID file path has changed, so the new binary won't detect the old instance.

Documentation fix from v0.4.2 and add timestamp on log.

• docs: fix incorrect pathes in manual (/tmp/dpibreak.pid -> /run/dpibreak.pid, /tmp/dpibreak.log -> /var/log/dpibreak.log)
• log: print timestamp on log output
• windows: fix regression introduced on v0.4.2 on service mode

For new features added on v0.4 (which introduce windows service and daemonize on linux), see v0.4.0 release note.

v0.4.2

Fix from v0.4.1. Linux only — Windows users do not need to update from v0.4.0 or v0.4.1

NOTE for windows users: this version contains critical regression related to windows service. DO NOT USE THIS VERSION FOR WINODWS! use v0.4.3 instead.

Upgrading from v0.4.0/v0.4.1: Stop any running dpibreak instance (sudo pkill dpibreak) before upgrading. The PID file path has changed, so the new binary won't detect the old instance.

• Move PID file to /run/dpibreak.pid and daemon log file to /var/log/dpibreak.log. (Fixes #16)
• Add root privilege check on startup. (#16)
• Fix log file being truncated when daemonize fails. (#17)

For new features added on 0.4 (which introduce windows service and daemonize on linux), see v0.4.0 release note.

v0.4.1

NOTE: this version contains a bug; workaround is simple. See #16.

Linux only hotfix:

Fixed issue where running dpibreak again while a daemon instance was active would silently delete nftables rules and then fail with nfqueue binding error (#6, #13). Non-daemon mode now also acquires PID file lock to ensure only one dpibreak instance runs on the system at a time, whether daemon or non-daemon.

• TL;DR: Enforce single dpibreak instance per system on Linux.

For new features added on 0.4 (which introduce windows service and daemonize on linux), see v0.4.0 release note.

• Add option -D, --daemon.
  • linux: run as a background daemon.
  • windows: run as Windows service entry point.
• windows: add service_install.bat, service_remove.bat for Windows service management.
• windows: add WINDOWS_GUIDE.txt with Korean translation.

Feature addition.

• Add --fake-autottl: dynamically set fake packet’s ttl.

v0.2.0

Note: please update to v0.2.1 or later. (See v0.2.1 release note)

Introduce experimental --fake-badsum. This option intentionally corrupts TCP checksums, so packets likely won't pass through most routers/firewalls. Deprecated --loglevel will be usable until v1.0.0.

• Add option --fake-badsum to inject packets with incorrect TCP checksums.
• Deprecate --loglevel in favor of --log-level.
• windows: prevent start_fake.bat comments from being echoed on startup.
