4a41e31822 feat(ebpf): Apache HTTP capture + nginx multi-kernel validation
**Apache HTTP capture via apr_socket_recv** :
- Uprobe sur libapr-1.so.0 (Apache Portable Runtime)
- Compatible tous kernels 4.18+ (CentOS 8, Rocky 9/10)
- Configuration unifiée : servers: ["nginx", "apache"]

**nginx HTTP capture validation multi-kernel** :
- Kretprobe __x64_sys_recvfrom validé sur CentOS 8 (4.18)
- Rocky 9 (5.14) et Rocky 10 (6.12) confirmés
- Contourne limitation tracepoint sys_exit_recvfrom

**Documentation** :
- docs/TEST_BUILD_STACK.md : stack complète test/build (VMs, Docker, RPMs)
- services/ja4ebpf/docs/APACHE_HTTP_VALIDATION.md : validation Apache
- services/ja4ebpf/docs/NGINX_MULTI_KERNEL_VALIDATION.md : validation nginx
- docs/architecture.md + docs/services/ja4ebpf.md mis à jour

**Tests unitaires Apache** :
- internal/loader/apache_test.go : tests libapr, paths, structures BPF
- internal/correlation/apache_test.go : tests corrélation HTTP Apache

**Packaging** :
- RPM spec mis à jour (version 0.3.0-1, changelog complet)

cba1cca180 refactor(ebpf): simplify web server configuration with server list
Refactor uprobes configuration to use a single server list instead
of separate nginx_bin_path and apache_enabled options.

Configuration changes:
- Uprobes.Servers: []string (was: NginxBinPath + ApacheEnabled)
  - Accepts: ["nginx"], ["apache"], or ["nginx", "apache"]
  - Can also use "both" to enable both servers
- Environment variable: JA4EBPF_UPROBES_SERVERS (was: separate vars)

Examples:
  YAML:
    uprobes:
      enabled: true
      servers: ["nginx", "apache"]

  Environment:
    JA4EBPF_UPROBES_SERVERS=nginx,apache

Code changes:
- Generic loop over cfg.Uprobes.Servers for attachment and consumption
- Remove duplicate checks for Enabled/ApacheEnabled
- Update attachNginxUprobesWithRetry to use default nginx path
- Update attachApacheUprobesWithRetry to remove ApacheEnabled check
- Update documentation to reflect both nginx and apache support

f0c8fe81c6 feat(ja4ebpf): add multi-interface TC, LPM_TRIE ignore_src, unit tests, and fix bugs
- Add multi-interface TC attachment (default "any" = all UP interfaces)
- Add BPF LPM_TRIE map ignored_src for kernel-side CIDR filtering
- Add userspace ignore_src filtering for SSL/accept4 path via net.IPNet.Contains()
- Add AcceptCache for fd→SessionKey correlation with TTL and Close()
- Add 5 test files covering writer, procutil, dispatcher, accept_cache, and cmd
- Fix formatTCPOptions infinite loop on EOL (case 0 break→return)
- Fix pseudoOrderToShort panic on empty slice (negative cap)
- Fix AcceptCache goroutine leak (add done channel + Close())
- Update config.yml.example with interfaces, listen_ports, ignore_src
- Rewrite docs/services/ja4ebpf.md (was massively stale: XDP, RingBuffer, etc.)
- Fix stale XDP/RingBuffer references in docs/architecture.md, thesis, tls.go

f88b739992 feat(e2e): add distributed E2E test framework with parametric traffic generation
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.

3b047b680a fix(ja4ebpf): split bpf2go generate into Ja4Tc + Ja4Ssl, fix RPM systemd-rpm-macros
- 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
