Some checks failed
Build RPM Package / Build RPM Packages (CentOS 7, Rocky 8/9/10) (push) Has been cancelled
feature: 1.1.18
+- FEATURE: Add comprehensive metrics for capture and TLS parser monitoring
+- Capture metrics: packets_received, packets_sent, packets_dropped (atomic counters)
+- Parser metrics: retransmit_count, gap_detected_count, buffer_exceeded_count, segment_exceeded_count
+- New GetStats() method on Capture interface for capture statistics
+- New GetMetrics() method on Parser interface for parser statistics
+- Add DefaultMaxHelloSegments constant (100) to prevent memory leaks from fragmented handshakes
+- Add Segments field to ConnectionFlow for per-flow segment tracking
+- Increase DefaultMaxTrackedFlows from 50000 to 100000 for high-traffic scenarios
+- Improve TCP reassembly: better handling of retransmissions and sequence gaps
+- Memory leak prevention: limit segments per flow and buffer size
+- Aggressive flow cleanup: clean up JA4_DONE flows when approaching flow limit
+- Lock ordering fix: release flow.mu before acquiring p.mu to avoid deadlocks
+- Exclude IPv6 link-local addresses (fe80::) from local IP detection
+- Improve error logging with detailed connection and TLS extension information
+- Add capture diagnostics logging (interface, link_type, local_ips, bpf_filter)
+- Fix false positive retransmission counter when SYN packet is missed
+- Fix gap handling: reset sequence tracking instead of dropping flow
+- Fix extractTLSExtensions: return error details with basic TLS info for debugging
