Evgeny	d0d4199273	etcp: unified send hook via etcp_udp_send, remove loss_rate, add dummynet_filter inline mode, rewrite BGP test - Add etcp_udp_send_fn_t hook typedef, send_hook/send_hook_ctx fields to ETCP_LINK - Implement etcp_udp_send() wrapper — all UDP sends go through one point - Remove loss_rate from ETCP_SOCKET, CFG_SERVER, config parser, send path - Add dummynet_filter: inline send-hook with loss/delay, no proxy socket needed - Rewrite test_bgp_route_exchange: 3-node chain A(2 links)↔B↔C, 7 phases with dummynet_filter-based link failure/recovery simulation - Clean up tests: remove skeleton test_routing_mesh, 6 debug/stale test files - Refactor test_etcp_simple_traffic and test_pkt_normalizer_etcp (remove debug spam) - Fix test_etcp_two_instances: remove private field access, fix false PASS on timeout	5 months ago
Evgeny	61fee27478	congestion: burst-based BW measurement + adaptive inflight (slow start/cong avoidance/loss response) New features: - get_time_us() in lib/u_async.c/h for µs-precision timing - Burst measurement (ETCP_SECTION_MEAS_TS 0x07, MEAS_RESP 0x08, FILLER 0x09) - 12 MTU packets sent at line rate, receiver measures inter-packet gaps - Burst triggered when link saturated + min 500ms interval - Result: measured BW -> bandwidth for shaper, burst_target_bdp for window cap - 3-phase adaptive inflight in link_stats_timer_cb: - Slow start: windows doubles each RTT, exits on loss/RTT spike/threshold - Congestion avoidance: additive increase, proportional RTT shrink, multiplicative loss shrink - Burst target cap: inflight_lim <= burst_target_bdp * 1.1 - Dynamic optimal_inflight = sum(link->inflight_lim_bytes), recalculated on change - Adaptive win_timebase = rtt/2 (was hardcoded 10ms) Fixes: - dummynet.c: shaper formula fixed (80000 -> 80) - dummynet.c: queue_data_put call fixed (3 args -> 2) - etcp.c: SIZE ERROR format string (missing log_name argument) - etcp_request_pkt: FILLER leaves room for PAYLOAD overhead Tests: - test_etcp_congestion.c: single-threaded, 5-phase BW/delay/loss test - sender + receiver + dummynet in one uasync - CSV metrics output every 100ms - All 29 existing tests pass	5 months ago

Evgeny	6aedf5fe91	Replace buggy get_default_route_ip() with get_outgoing_local_ip() for reliable local IP detection - Add lib/getmyip.c/h with get_outgoing_local_ip() using UDP connect+getsockname - Update etcp_socket_add() to use new function for 0.0.0.0 and :: bindings - Support both IPv4 (8.8.8.8) and IPv6 (2001:4860:4860::8888) auto-detection - Remove broken get_default_route_ip() from platform_compat (it returned gateway IP, not local IP) - Keep get_interface_ip_by_index() for explicit interface bindings - Update Makefile.am to include new getmyip module	5 months ago
Evgeny	724a9ff5c7	Add getmyip module for reliable local IP detection - New lib/getmyip.c/h with get_outgoing_ip(), get_default_local_ip(), get_local_ip_by_index() - Uses UDP connect + getsockname instead of /proc/net/route parsing - Supports both IPv4 and IPv6 - Updated etcp_socket_add() to use new functions for interface_addr detection	5 months ago
