Author	SHA1	Message	Date
Evgeny	a34035f41f	ETCP: Fix protocol parsing and crypto nonce handling - Fixed ACK section parsing (elm_cnt and till offset) - Fixed payload section to include seq number in packet - Fixed assembly trigger condition (last_delivered_id+1==seq) - Crypto: Added nonce transmission in encrypted packets - Crypto: Fixed nonce generation with usec timestamp - Reduced debug verbosity in connection handling - Added unknown section type handling	2 months ago
Evgeny	41626a02c3	Fix ll_queue callback signature and add debug utilities 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	2 months ago
Evgeny	3ddfb79338	Backup before replacing all printf with DEBUG_ macros in tests	2 months ago
Evgeny	1bafe6a681	Backup before fixing etcp_connections list addition	2 months ago
Evgeny	d74f76a5a0	Fix: Resolved double free in timeout_heap_pop() and test_etcp_simple_traffic bind conflict - 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	2 months ago
Evgeny	64489fa194	Add comprehensive ETCP traffic flow debugging tests Implemented multiple levels of ETCP traffic debugging tests: 1. test_etcp_minimal.c - Basic packet analysis and section parsing: - Single section payload packets - Multi-section packets (TIMESTAMP, ACK, PAYLOAD) - Connection establishment packets (INIT_REQUEST, INIT_RESPONSE) - Detailed section-by-section analysis with timing 2. test_etcp_simple_traffic.c - TUN-less traffic simulation: - Direct packet injection and analysis - Connection state simulation - Traffic generation and processing - Comprehensive packet capture and analysis 3. test_etcp_traffic_flow.c - Full instance simulation: - Two-instance setup with traffic analysis - Packet capture hooks in ETCP pipeline - Traffic analyzer with detailed metrics - Connection establishment debugging Key debugging features added: - Section-by-section packet parsing and validation - Packet ID tracking and sequence analysis - ACK processing with timestamp correlation - Connection handshake simulation - Retransmission request handling - Multi-section packet composition analysis - Traffic flow metrics and timing analysis All tests use comprehensive DEBUG_* output for detailed traffic flow tracing: - Packet type identification - Section length validation - Payload content analysis - Connection state tracking - Timing and sequence verification This enables thorough debugging of ETCP protocol traffic flow, packet processing, and connection establishment without requiring TUN devices or network setup.	2 months ago
