- Added CFG_ALLOWED_KEY struct with binary key storage (64 bytes) for fast memcmp comparison
- Implemented parsing of [allowed_keys] section with allow_all flag and per-key entries
- Added key validation in etcp_connections.c server handler (errorcode=8 for rejected keys)
- Default behavior: deny all if [allowed_keys] section is missing or allow_all=0 with no keys
- Added proper memory cleanup and debug logging for allowed_keys configuration
- Updated all test configs to include [allowed_keys] allow_all=1 for backward compatibility
- etcp_connections.c: парсинг NAT IP через memcpy (сохраняет NBO)
- route_bgp.c: убраны ntohl() для IP в NAT detection и route_bgp_send_nat_info
- route_ping.c: убран htonl() для IP в ping request
- тесты: обновлены ожидания NBO для nat_ip
- route_ping.c: burst mode - send next ping immediately on response
- route_ping.h: add target_ipv4/target_port/pubkey to BGP_PING_REQUEST
- test_nat_detection.c: add test for ping without embedded pubkey
- test_etcp_simple_traffic.c: use dynamic ports + fix timebase units
- Makefile.am: show test execution time in ms
- serialize.h/c: universal binary serialization for structures with
variable-length fields (ASCIIZ, ARRAY) using pointers
- Auto allocation via u_malloc during deserialization
- Support for header (arbitrary bytes at buffer start)
- serialize_encode(): serialize structure to buffer
- serialize_decode(): deserialize from buffer (without header)
- serialize_free(): free structure and all its pointers
- tests/test_serialize.c: unit tests
- Refactored test_routing_mesh to use proper ETCP + normalizer flow
- Removed duplicate init_connections() calls that caused 'Address already in use'
- Improved error reporting in etcp_link_new()
- Test now respects single mainloop architecture
