# nx9-wg — Native Linux Integration, Drift & Convergence Verification Script
|
|
# ============================================================================
|
|
#
|
|
# PURPOSE
|
|
# -------
|
|
# Rigorous integration testing of the three native Linux execution planes:
|
|
# 1. NativeLinuxWireGuardEngine (RTNETLINK + Generic Netlink)
|
|
# 2. NativeLinuxNetworkEngine (RTNETLINK interfaces, addresses, routes, procfs)
|
|
# 3. NativeLinuxNftablesEngine (In-process libnftables / Netfilter Netlink)
|
|
#
|
|
# Proves:
|
|
# SQLite desired state -> Reconcile Plan -> Native Engines -> Linux Kernel ->
|
|
# Live Diagnostics -> Drift Injection -> Reconcile Apply -> Convergence
|
|
#
|
|
# SAFETY INVARIANTS
|
|
# -----------------
|
|
# - Strict isolation: uses isolated test interface name (nx9t$$)
|
|
# - Baseline pre-capture to /tmp/nx9-integration-baseline-$$
|
|
# - Restores initial forwarding state on exit
|
|
# - Cleans up only test-created interface, route, and table inet nx9_wg
|
|
# - NEVER flushes unrelated routes, addresses, or host nftables tables
|
|
# - Safe trap handling for EXIT, SIGINT, SIGTERM
|
