- TC ingress hook captures TCP SYN (L3/L4) and TLS ClientHello - Uprobes on SSL_read/SSL_set_fd capture decrypted TLS data - Kprobes on accept4 correlate socket FDs to client IP:port - JA4 fingerprint computed from parsed TLS ClientHello - HTTP/2 SETTINGS and WINDOW_UPDATE extracted from decrypted streams - Session manager with sharded map (256 shards) and GC goroutine - Slowloris detection: sessions with no requests after 10s threshold - ClickHouse batch writer to ja4_logs.http_logs_raw (raw_json) - All tests pass: 17 parser + 10 correlation tests Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
