* linux: drain rxring before nfqueue in poll loopdilluti0n2026-04-081-7/+7
| | | | | | | | When both fds are ready in the same wakeup, the SYN/ACK that triggered rx_ready is causally prior to the ClientHello waiting in the nfqueue. Process the rxring first so HopTab is populated before handle_packet runs find_hop, reducing the race window for HopLookupError::NotFound under load.

* linux: add IPv6 SYN/ACK BPF filter and increase rxring frame sizedilluti0n2026-03-062-20/+25
| | | | | | | | | | | | | | Previous BPF filter only matched IPv4 due to tcpdump failing to generate a correct combined IPv4/IPv6 filter. Replaced with manually split filter that handles both ip and ip6 paths. Also increase FRAME_SIZE from 128 to 256 to resolve this error: [WARNING] put_hop: IPv6 Packet Error: Not enough data to decode 'IPv6 packet'. 80 byte(s) would be required, but only 62 byte(s) are available based on the slice length. tpacket_hdr(~66) + eth(14) + ipv6(40) + tcp+options(60) = ~180 bytes, which exceeded the previous 128-byte limit.

* windows: fix buffer size to 65536hskimse2026-03-011-1/+1
| | | | This size is for windivert buffer, not internal pkt buffer capacity.
* windows: simplify packet handling with recv_loop macrohskimse2026-03-011-59/+28
| | | | | | | | | Replace generic spawn_recv with recv_loop macro that encapsulates the buffer allocation and receive loop. Divert handle now runs directly on the main thread, while sniff handle spawns a dedicated thread only when fake_autottl is enabled. This eliminates the mpsc channel, Event enum, and the race condition where concurrent open_handle calls during driver initialization could cause error 1058.
* windows: remove RUNNING flag and trap_exithskimse2026-03-011-30/+6
| | | | | | Non-daemon mode exits via process::exit(0) on Ctrl-C, and daemon mode is managed by SCM, so the RUNNING atomic flag and graceful shutdown loop are both unnecessary. Remove them along with the ctrlc handler.
* windows: exit immediately on Ctrl-C in non-daemon modedilluti0n2026-03-011-1/+4
| | | | | | | | | | In non-daemon mode, WinDivert driver closes all handles on process exit, so explicit cleanup is unnecessary. Call std::process::exit(0) directly from the Ctrl-C handler instead of relying on RUNNING flag and graceful shutdown loop. Also move trap_exit() call before spawn_recv() to ensure the handler is registered before any threads are spawned.
* Move cleanup/trap_exit/RUNNING to platform modulesdilluti0n2026-03-012-37/+40
| | | | | | | | - Remove global RUNNING, trap_exit, EnsureCleanup, MESSAGE_AT_RUN from main.rs - Move each into platform-specific modules (linux.rs, windows.rs) - Move MESSAGE_AT_RUN to platform.rs - Inline cleanup logic into run() instead of separate cleanup() fn - Remove service_run_1() indirection in windows.rs

* windows: add close WinDivert handles on thread exitdilluti0n2026-02-271-19/+21
| | | | | | Move handle lifecycle into spawn_recv so each handle is properly closed when RUNNING becomes false. Filter and flags are passed in instead of a pre-opened handle.

* linux: fix rxring initialized even if fake_autottl not enableddilluti0n2026-02-262-27/+42
| | | | | | | Conditionally initialize rxring only when fake_autottl is enabled. Extract poll_once() using libc::poll directly; fd=-1 trick eliminates the need for conditional branching on optional rxring fd, as poll sets revents=0 for negative fds per POSIX. Drop nix poll feature.
* linux: refactor run() into open_nfqueue/open_rxring helpersdilluti0n2026-02-262-54/+60
| | | | | | | | Extract nfqueue initialization (open, bind, set O_NONBLOCK) and rxring initialization (cBPF filter, open) into separate functions. Inline BorrowedFd scope as a let binding to eliminate floating q_ready/rx_ready declarations. Move SYNACK_443_CBPF const into open_rxring.
* linux: rxring: implement current_packet and advancedilluti0n2026-02-262-24/+62
| | | | | | | | - Split next_packet into current_packet (read) and advance (release) to avoid TOCTOU between kernel overwrite and packet processing - Add current_frame helper to avoid duplicated pointer arithmetic - Switch AF_PACKET socket to ETH_P_ALL for future IPv6 support - Add FRAME_SIZE comment explaining 128B is sufficient for IP header

| | | | | | Pass destination address from PktView::daddr() at call site instead of re-extracting it from raw bytes inside send_to_raw. Windows side ignores the argument. Also add #[inline] to PktView accessor methods.

* opt: decouple set_opt() from loggingdilluti0n2026-02-162-7/+12
| | | | | | | | | | | | | | | | | | | | | | set_opt() was logging each option as it set them, which created a tight coupling between option initialization and log output timing. This was particularly problematic for daemon mode: daemonize must happen after set_opt() (to know whether -D was passed) but before logging (so output goes to the log file, not stdout). Split into set_opt() -> InitializedOpts and InitializedOpts::log(), using a typestate pattern to enforce at compile time that log() cannot be called before set_opt(). This lets each platform's bootstrap() handle daemonization between the two steps: let initialized = opt.set_opt()?; platform::bootstrap()?; // daemonize here if needed initialized.log(); // now safe to log Also: - Move daemonize_1() into platform::bootstrap() on both platforms - Make daemonize_1() / service_main() private to their platform modules - Fix the long-standing TODO about using log_println in daemonize()

* Consolidate setup logic into run()dilluti0n2026-02-151-2/+7
| | | | | | | | | | | The bootstrap/run separation was unnecessary. Move all initialization (cleanup + nftables setup): into run() and skip bootstrap in daemon mode. We repurpose the bootstrap() function to only run in non-daemon mode for future foreground-only initialization. - Add OPT_DAEMON option to detect daemon mode - Move cleanup() and install_rules() from bootstrap() to run() - Make bootstrap() a no-op (only called in non-daemon mode)
