feat: pipeline L7 HTTP complet + infrastructure tests VM
Correctifs pipeline L7 (uprobe SSL_read) :
- uprobe_ssl.c : ssl_set_fd ne retourne plus tôt quand fd_conn_map est
vide (accept4 non disponible en Docker). Sauvegarde ssl_ptr→{fd,0,0}
pour permettre le fallback /proc côté Go.
- main.go : consumeSSLEvents reécrit avec routeur magic-bytes complet :
* HTTP/2 preface → extraction SETTINGS + conversion correlation.HTTP2Settings
* HTTP/1.x requête → method, path, query, headers, header_order_sig
* HTTP/1.x réponse → status_code
* Fallback /proc/<tgid>/fd/<fd> quand src_ip=0 (accept4 absent)
- writer/clickhouse.go : export header_order_signature ajouté
Nouveaux packages :
- internal/parser/http1.go : parseur HTTP/1.x (IsHTTP1Request,
ParseHTTP1Request, IsHTTP1Response, ParseHTTP1Response)
- internal/parser/http1_test.go : 11 tests unitaires (28 total passent)
- internal/procutil/proc_lookup.go : résolution fd→IP via /proc avec cache
TTL 5s (FDCache). Supporte /proc/PID/net/tcp et tcp6, IPv4-mappé IPv6.
Infrastructure tests VM (tests/vm/) :
- Vagrantfile : VM Rocky Linux 9 KVM, 4 CPU / 4 GB RAM
- provision.sh : installation toolchain eBPF + Go + Docker + nginx
- run-tests-vm.sh : suite de test complète dans la VM (L3/L4+TLS+L7)
- README.md : guide d'installation et d'utilisation
- Makefile : cibles vm-up, vm-down, vm-ssh, test-vm-nginx, test-vm-all,
vm-rebuild-ja4ebpf
Corrections stack Docker :
- Dockerfiles nginx/apache/nginx-varnish/hitch-varnish : suppression des
références à shared/go/ja4common/ (répertoire supprimé)
- clickhouse-init.sh : restauré depuis git, seed anubis_ua_rules obsolète
supprimé (table REGEXP_TREE supprimée du schéma)
- traffic-gen : ajout HTTP/1.0 (http.client) et HTTP/2 (httpx)
- verify_db.py : script de vérification 35 checks (L3/L4/TLS/L7/corrélation)
- run-stack-tests.sh : phase 6 verify_db ajoutée
