Add uprobe_ssl_write_entry/uretprobe_ssl_write_exit to capture server HTTP
responses via SSL_write with direction=1. Implement full HPACK decoder
(RFC 7541 static table, multi-byte integers, literal representations) for
HTTP/2 header extraction. Add AcceptCache mapping {tgid,fd}→SessionKey
from accept4 events as authoritative source for SSL correlation when BPF
ssl_conn_map has src_ip=0. Add ip_total_length to tcp_syn_event BPF struct.

Add run-e2e-test.sh with CLI parameters (--hits, --http-ratio, --dns, --tls,
--src-ips, --keep-analysis, --up) for configurable traffic generation. Traffic
runs from VM endpoints with multiple source IPs (alias IPs on eth0) to produce
distinct sessions for the ML pipeline. Fix curl TLS flags (--tlsv1.2 instead
of --tls-v1-2), skip redundant local verification in distributed mode, and
fix dashboard is_available() cache that never retried after ClickHouse recovery.

Add .gitignore rules for generated CSV data, eBPF compiled objects,
and vmlinux.h header. Remove 19 tracked files (~175 MB) that can be
regenerated from scripts (generate_*.py), bpftool, or bpf2go.

- Dockerfile.package: migre go-builder de golang:bookworm (Debian) vers
rockylinux:9, installe Go depuis le tarball officiel, remplace apt par
dnf (clang llvm libbpf-devel bpftool)
- Suppression du champ 'correlated' de l'agent ja4ebpf : avec eBPF/XDP,
la corrélation L3/L4↔L7 est toujours implicite par présence des champs.
Supprimé de : session.go, manager.go, main.go (x5), clickhouse.go
- Thèse (6 corrections listées + cohérence correlated) :
1. §3.5 + §3.9.1 : SSL_read retourne des octets bruts sans respecter les
frontières H2 → buffer circulaire de réassemblage en Go userspace
2. §3.1 : supprimé libpcap + CAP_NET_RAW, remplacé par définition uprobe
3. §4 + §7 : compte exact 96 features en 8 familles (Famille 1–8),
supprimé taxonomie F1–F11 obsolète, tous les totaux mis à jour
4. §2.4 + §8 : remplacé 7 fausses URLs arXiv par [Référence à vérifier]
5. §4 Famille 2 : ja4_drift_ratio → renvoi à Famille 8 (définition complète)
6. §6.4 : ajouté limite 'Overhead de l'uprobe SSL_read'
+ §3.6 : supprimé correlated=0/1 du texte architectural

- 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

- Ajoute dict_browser_h2 dans /reflists (lecture seule via dict_browser_h2)
- Nouveaux endpoints API :
GET /api/browser-signatures/entries — liste browser_h2_signatures
(fallback dict CSV si migration 06 non appliquée)
POST /api/browser-signatures/entries — ajout fingerprint + reload dict
DELETE /api/browser-signatures/entries — suppression + reload dict
- Page /browsers : 2 nouvelles sections
'Base de signatures H2' — tableau des 10 fingerprints, form d'ajout,
mode lecture seule automatique si migration 06 non appliquée
'Règles de scoring browser_matcher.py' — tableau statique des 7 dimensions
(poids, valeurs par famille, seuils de bypass)
- Integration : browser_h2.csv copié dans user_files au démarrage ClickHouse

- 350K browser rows (14K IPs) using real JA4s from browser_ja4.csv
- 100K scanner rows (3K IPs) with vuln/cred/scraper/DDoS sub-categories
- 30K legit bot rows (2K IPs) from real bot_ip.csv CIDRs
- 20K AI bot rows (1K IPs) for GPTBot, ClaudeBot, etc.
Key improvements:
- Load browser_ja4.csv at startup, match JA4 to browser family
- Load bot_ip.csv to generate IPs from real Googlebot/Bingbot CIDRs
- Hard-coded ISP /24 prefixes from real ASNs (Comcast, Orange, DT, etc.)
- Realistic navigation patterns with Referer chains and cookies
- Sec-CH-UA headers for Chromium browsers (modern_browser_score >= 50)
- Batch size increased to 2000, progress reporting every 10K rows
- New CLI args: --rows, --ips, --seed, --data-dir
- Bot JA4s are synthetic hashes guaranteed NOT in browser_ja4.csv
Also updated:
- Dockerfile: COPY *.py (was missing seed_clickhouse.py)
- docker-compose.yml: mount scripts/data as /app/data for CSV access
- run-tests.sh: updated seeder description comments

3 SQL files were missing from the docker-compose.yml volume mounts:
- 10_perf_indexes.sql (performance indexes)
- 11_views.sql (dashboard views)
- 12_thesis_features.sql (thesis §5 MVs and views)
Also make 10_perf_indexes.sql non-fatal in init script since ALTER TABLE
ADD INDEX may fail if index already exists.

- EIF: Extended Isolation Forest via isotree (fallback to sklearn IF)
- Benford's Law deviation feature on inter-request timing
- Lag-1 autocorrelation feature for cadence analysis
- Validation gate: reject model if val_anomaly_rate > 20%
- Feature pruning: remove variance < 1e-6 features before training
- Quantile drift: replace N(μ,σ) synthetic with quantile interpolation
- Thread safety: Lock for _service_healthy/_consecutive_failures
- Score normalization: inverted to [0,1] where 1=most anomalous
SQL: add lag1_autocorrelation + benford_deviation to view_thesis_features_1h
Tests: 10 new test functions covering all improvements
Integration: verify_mvs.py checks new thesis feature columns

deploy_views.sql (v13 → v14):
- CRITICAL: ml_detected_anomalies ORDER BY (src_ip) → (src_ip, ja4, host, model_name)
ReplacingMergeTree was collapsing all detections to 1 row per IP on merge
- Add PARTITION BY toDate + ttl_only_drop_parts on all 4 data tables
- ml_all_scores TTL 3d → 7d; ml_detected_anomalies TTL 30d → 7d
- agg_host_ip_ja4_1h + agg_header_fingerprint_1h: add partition + TTL 7d
- view_ip_recurrence: add WHERE detected_at >= now() - 7 DAY (was full scan)
- Remove dead views: summary/timeseries/threat_dist/variability
- Add view_dashboard_entities (fixes HTTP 500 in clustering/incidents/fingerprints)
- Add view_dashboard_user_agents (fixes HTTP 500 in fingerprints/metrics)
- Add view_ai_features_24h (enables ENABLE_MULTIWINDOW in bot_detector)
- Mark max_requests_per_sec as DEPRECATED (always 0)
New files:
- correlator/sql/migrations/01_ttl_adjustments.sql: ALTER TABLE migration
- tests/integration/verify_mvs.py: MV pipeline verification assertions
- docs/THESIS_HTTP_Traffic_Detection.md: detection techniques thesis
All DB references use ja4_processing/ja4_logs (no mabase_prod).
