Whitelist local IPv6 CIDRs when airgapping nodes

twz123 commented 2 weeks ago

Description

This does the same to IPv6 that's done for IPv4. Allows the airgap test to function if the SSH connection runs via IPv6. Also: check if ip6table_filter is already loaded before trying to modprobe it. This allows the integration test to work without sudo/doas when the module is already loaded.

Apparently something changed on the GitHubGitHub Runner Image between 20240603.1.0 and 20240609.1.0 which makes the airgap tests fail? This seems to fix it... :thinking:
