- Increase MAX_TLS_PAYLOAD from 512 to 2048 bytes to capture full
TLS ClientHellos (modern browsers/curl send 1000-1543 byte ClientHellos)
- Fix ParseClientHello to tolerate XDP-truncated payloads: clamp
recordLength and chLen to available data instead of returning error
- Fix cipher suites, compression, extensions truncation to use clamping
- Fix consumeSynEvents struct field offsets: dst_ip (4 bytes at offset 4)
was not accounted for, causing all L3/L4 metadata to be read from
wrong positions (TTL was actually dst_ip[0], windowSize was dst_port, etc.)
- Add parseTCPOptions() to extract MSS and Window Scale from raw TCP options
(C code sets defaults of mss=0, window_scale=0xFF, expects Go to parse)
- Fix consumeAcceptEvents: skip zero-IP events to avoid phantom sessions
- Fix consumeSSLEvents: filter zero-IP/port events when proc fallback fails
- Add missing consumeHTTPPlainEvents goroutine (was defined but never called)
- Fix race condition: SYN consumer sets Correlated=true if TLS already present
- Update tls_hello_event struct offsets in Go consumer (payload_len now at
offset 2054, was 518, due to payload array growing from 512 to 2048 bytes)
- Remove debug logging from consumers and GC
E2E verified: HTTP plain (port 80) and HTTPS (port 443) both produce
fully correlated sessions in ClickHouse with correct:
- ip_meta_ttl=64, ip_meta_df=true, ip_meta_id
- tcp_meta_window_size=64240, tcp_meta_window_scale=10, tcp_meta_mss=1460
- ja4=t13i3010_1d37bd780c83_95d2a80e6515
- tls_alpn=http/1.1
- method=GET, path=/, header_order_signature=Host;User-Agent;Accept
- correlated=1

- Use two separate //go:generate directives (Ja4Tc for tc_capture.c, Ja4Ssl
for uprobe_ssl.c) to avoid duplicate LICENSE symbol and multi-file clang issue
- Update loader.go to hold tcObjs/sslObjs separately with correct field names:
UprobeSslSetFd, UprobeSslReadEntry, UretprobeSslReadExit,
KprobeAccept4Entry, KretprobeAccept4Exit
- Add systemd-rpm-macros to all three RPM build stages (el8/el9/el10)
so that %{_unitdir} macro resolves correctly
- RPMs now build successfully for el8, el9, el10

Exports http_logs from prod ClickHouse via HTTP API, imports into dev
with dynamic date shifting (max(time) → now() by default).
Features:
- Batch export in Native format (200K rows/batch, ~10s each)
- Auto date shift: prod max(time) aligned to current time
- --shift N: manual override (seconds)
- --days N: filter to last N days only
- --cron: silent mode for scheduled runs
- Staging table approach: export → staging → INSERT SELECT with shift → cleanup
Tested: 3,054,122 rows imported in ~3 minutes, dates 2026-04-03→2026-04-09.
