Unit Tests / test (push) Successful in 7m29s
wg-quick creates an nftables 'preraw' table per interface that drops decrypted ICMP replies arriving on any other interface. If a test run crashes before bring_down(), the table persists and silently kills pings on subsequent runs (handshake succeeds, replies are decrypted, but the stale table drops them before the ping process sees them). Extend cleanup_stale_e2e_interfaces() to also delete any orphaned wg-quick-pic-e2e-* nftables tables found on the host. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
