* linux: extract process execution into `exec_process` helperdilluti0n2025-12-291-17/+29
| | | | | | | | Introduce exec_process() to handle external command execution, stdin piping, and error reporting. Now cleanup() and apply_nft_rules() call exec_process() to call modprobe, nft respectively. This improves error handling for cleanup xt_u32.
* linux: ignore cleanup errors at startupdilluti0n2025-12-221-7/+3
| | | | | Do not log errors if cleanup fails during startup. Retain error logging for cleanup failures on shutdown.
* linux: switch to apply_nft_rules() from nftables-rs for rule settingdilluti0n2025-10-291-18/+13
| | | | | nftables-rs didn’t fit use case, so it was decoupled, and logging was improved.

* linux: add option `--nft-command`dilluti0n2025-10-292-10/+23

* windows: avoid ERR_INVALID_NAME when uninstalling WinDivertdilluti0n2025-10-061-2/+9
| | | | | | | `CloseAction::Uninstall` triggers ERROR_INVALID_NAME (0x8007007B) on Windows, likely due to the crate passing a non–NUL-terminated "WinDivert" string to `OpenServiceA`. For now, skip uninstallation and just close the handle normally. Added a FIXME comment with details.
* platform: windows: close handle and uninstall driver sanelydilluti0n2025-10-061-9/+19

* platform: windows: only divert clienthello packet to userspacedilluti0n2025-10-032-2/+4
|
* platform: linux: filter only TLS ClientHello packets on nftablesdilluti0n2025-10-031-0/+21
| | | | | | | | Add additional nftables match expressions to detect TLS records (ContentType 0x16 = Handshake): and specifically ClientHello (HandshakeType 0x01):. Packets matching this pattern are queued to NFQUEUE. Mark xt_u32 as supported when nftables filtering is successfully applied.
* platform: linux: add nftables support with iptables fallbackdilluti0n2025-10-031-11/+112
| | | | | | | | | | Introduce nftables rules under a dedicated "dpibreak" table and chain. Traffic on TCP port 443 is queued using NFQUEUE. If nftables is not supported, fall back to the existing iptables-based rules for both IPv4 and IPv6. Also update cleanup logic to remove nftables table if used, or iptables rules otherwise.
* platform: linux: split iptables helpers on bootstrap/cleanupdilluti0n2025-09-271-14/+25

* Refactor packet sending into split_packet_1 helperdilluti0n2025-09-151-9/+24
| | | | | | | * Extracted: repeated split/send/sleep logic from `handle_packet` into new `split_packet_1` function for clarity and reuse. * Simplifies: `handle_packet` by replacing manual steps with a single call.
* Refactor handle_packet to reuse external buffer for packet handlingdilluti0n2025-09-114-9/+16
| | | | This removes unnecessary allocations per packet handling.
* log: add splash! macro and centralize no-splash handlingdilluti0n2025-09-074-30/+39
| | | | | | | | | | | | | * Introduce: `splash!` macro in `log.rs` to print startup messages conditionally, based on `--no-splash` flag. * Move: `NO_SPLASH` management into `log.rs` with helper functions: (`set_no_splash`, `no_splash`). * Remove: old `splash()` function in `main.rs` and replace with `splash!` macro usage. * Set: default `LogLevel` according to build profile (Debug → Debug, Release → Warning). * Print: unified startup messages across Linux and Windows, including `MESSAGE_AT_RUN`.

|
* Add flag --loglevel to set loglevel on runtimedilluti0n2025-09-032-10/+51
| | | | | | | | | | | | | | | * Introduce: `DEFAULT_LOG_LEVEL` and `LOG_LEVEL_OVERRIDE` (OnceLock) in log.rs. * Add: `set_log_level()` and `current_log_level()`; gate defaults by `debug_assertions`. * Implement: `FromStr` for `LogLevel` with a proper error type (`ParseLogLevelError`). * Update: `log_println!` to respect `current_log_level()` and use `format_args!`. * Extend: CLI: `--loglevel <debug|info|warning|error>` and reflect it in `usage()`. * Replace: ad-hoc prints with `log_println!` and plumb parsed level into `set_log_level`.
* Tidy up LogLevel enum definitiondilluti0n2025-09-034-21/+21
| | | | | | * Remove: unused `Fatal` variant from `LogLevel`. * Update: comment on `Error` to indicate it represents unrecoverable errors.
* Use log.rs for conditional logging and centralized error reportingdilluti0n2025-09-032-3/+8
| | | | | | | | | * Set: `LOG_LEVEL` to `Debug` in debug builds and `Warning` in release builds via `#[cfg(debug_assertions)]`. * Replace: direct `println!` calls with `log_println!` for packet handling, warning messages, and argument parsing errors. * Ensures: consistent log formatting and respects the global log level configuration across the codebase.
* Refactor main to ensure cleanup via RAII guarddilluti0n2025-09-031-2/+31
| | | | | | | | | Introduce `EnsureCleanup` struct with a `Drop` implementation that calls `platform::cleanup()`. This guarantees cleanup is always performed after a successful bootstrap, regardless of how execution exits. Error handling is centralized in `main()`, where errors are logged once with their cause chain, and the process exits with the appropriate status code.
* Refactor prefixed logs to using log.rs, leaving Errors untoucheddilluti0n2025-09-033-10/+13

* platform: windows: log WinDivert handle creationdilluti0n2025-08-311-5/+7
| | | | | | Define the TCP:443 outbound filter as a constant and reuse it in WinDivert::network. Add a log message when the handle is successfully constructed for better visibility during runtime.

* Clear output buffer before writing in split_packethskim2025-08-231-2/+1
| | | | | | | Previously split_packet used truncate() after writing, which could leave stale data from earlier writes. This patch calls clear() before builder.write() to ensure the buffer only contains the current packet contents.
* Add command-line argument parsing and switch config to OnceLockhskim2025-08-232-26/+65
| | | | | | | | | | | This change introduces basic CLI parsing for --delay-ms, --queue-num (Linux only), and -h/--help. A usage() function was added, and error/help output now goes to stdout for consistency. Global constants DELAY_MS and QUEUE_NUM are replaced with OnceLock-based initialization, with helper accessors delay_ms() and queue_num(). The Linux platform code is updated accordingly to use queue_num() instead of a constant.
* Deduplicate CLI argument parsinghskim2025-08-231-7/+22
| | | | | Extracted common args.next() + parse logic into take_value() to remove duplication in --delay-ms and --queue-num handling.

| | | | | | | | - Change split_packet to take &mut Vec<u8> instead of returning Vec<u8> - Avoids allocating a new buffer for each split - Reserve additional capacity only when needed - Update handle_packet to reuse a single buffer across multiple calls - Add TODO for reusing IP header without extra copy
