- Fixed race condition: routing_add_conn called before etcp->normalizer was assigned
- Moved routing_add_conn from pn_init to etcp_connection_create after normalizer init
- Added routing.h include to etcp.c
- Fixed tests: disable routing callback on output_queue to keep packets for test verification
All 19 tests now pass.
- New struct tun_if with internal queue for incoming packets
- Single tun_init() does everything: create TUN, set MTU=1500, up, register in uasync
- tun_write() for outgoing packets
- tun_close() cleans up everything including queue
- Removed: tun_create, tun_set_ip, tun_set_up, tun_set_mtu, tun_read, tun_get_config
- Removed: utun_instance_register/unregister_sockets (now internal)
- Updated utun_instance to use new tun_if* pointer
- Updated test_etcp_two_instances for new API
- Removed usleep(5000) from all test event loops
- Changed to use single shared uasync for server and client instances
- Removed uasync_destroy from utun_instance_destroy to prevent double-free
- Added explicit uasync_destroy calls in all tests and main program
- Fixed segfault in test_pkt_normalizer_etcp and test_etcp_100_packets
- Added DEBUG_TRACE to all functions in etcp.c and etcp_connections.c
Tests now run without artificial delays and complete successfully.
- Fixed pkt_normalizer.c to send packets immediately instead of buffering
- Added queue_resume_callback() call in etcp.c after adding to output_queue
- Updated test to use simple checksum verification instead of pattern-based
- Added strict sequence order checking in test
- Reduced MAX_TEST_PACKET_SIZE to 1400 to fit in normalizer fragment
- Reduced TOTAL_PACKETS to 10 and TEST_TIMEOUT_MS to 5s for faster testing
- Fixed all incompatible pointer type warnings in src/etcp.c
- Fixed warnings in src/pkt_normalizer.c
- Fixed warnings in tests/test_etcp_simple_traffic.c
- Fixed warnings in tests/test_etcp_100_packets.c
- Fixed warnings in tests/test_ll_queue.c
- Fixed DEBUG_CATEGORY_ALL overflow warning in debug_config.h
- Fixed DEBUG_CATEGORY_LL_QUEUE redefinition warning in test_ll_queue.c
- Fixed write() unused result warning in test_u_async_comprehensive.c
- etcp_connections.c: Add incoming server connections to instance->connections list
- test_etcp_simple_traffic.c: Fix ETCP_FRAGMENT handling in check_packet_received()
- test_etcp_simple_traffic.c: Fix packet size check (ETCP adds headers to payload)
- Reduced debug verbosity in ll_queue.c and debug_config.c
Changes:
- ll_queue callback now receives only queue pointer and arg (no data)
- Added log_dump and addr_to_string utility functions
- Removed temporary backup files
- Updated AGENTS.md with additional guidelines
- Fixed compiler warnings in etcp.c and pkt_normalizer.c
- Fixed incorrect init_connections() call in test_etcp_simple_traffic.c (was calling server_instance instead of client_instance)
- Fixed double free in timeout_heap_pop() when handling deleted elements
- Enhanced NULL pointer safety in uasync_print_resources() by removing complex heap manipulation
- Added debug logging to timeout_heap_pop() for better error tracking
Test results: test_etcp_simple_traffic now passes without double free errors
