is that why the case where ipset != "" && prevIPSet != "" && ipset != prevIPSet is not possible?

Exactly. Here are the cases:
- Single IP change: A -> B (prevIPSet = "", ipset = "", prevIPNet = A, ipnet = B).
- Transition from multiple addresses to a single IP: {A, B} -> A (prevIPSet = "ipset name", ipset = "", prevIPNet = "", ipnet = A).
- Transition from a single IP to multiple addresses: A -> {A, B} (prevIPNet = A, ipnet = "", prevIPSet = "", ipset = "ipset name").

The ipset name is based on the rule ID, which determines that it will not change for a given rule.

is there any chance that we can use gomock.InOrder for those? Maybe not because of the last one (s2p3.After(s1p2))?

gomock.InOrder is a great way for these test cases! It can be used to optimize all the existing test cases.

…cy updates or deletions This commit addresses an issue where stale ipset or iptables chain is not deleted during NodeNetworkPolicy updates or deletions. The root cause is that the ipset or iptables chain is still referenced by other iptables rules during the deletion or update attempt. The fix ensures proper order of ipset and iptables synchronization. Signed-off-by: Hongliang Liu <[email protected]>
