Hi, Good day! Following Guillaume's suggestion, I've been working on updating all net self-tests to run in their respective netns. This modification allows us to execute all tests in parallel, potentially saving a significant amount of test time. However, I've encountered a challenge while making these modifications. The net selftest folder contains around 80 tests (excluding the forwarding test), with some tests using common netns names and others using self-defined names. I've considered two methods to address this issue: One approach is to retain the original names but append a unique suffix using $(mktemp -u XXXXXX). While this is a straightforward solution, it may not prevent future tests from using common names. Another option is to establish a general netns lib. Similar to the NUM_NETIFS variable in the forwarding test, we could introduce a variable like NUM_NS. This variable would define the number of netns instances, and all tests would use the netns lib to set up and clean up netns accordingly. However, this approach might complicate test debugging, especially for tests like fib_nexthops.sh, which relies on clear and visually netns names (e.g., me/peer/remote). I'm reaching out to gather your insights on this matter. Do you have any suggestions or preferences regarding the two proposed methods, or do you have an alternative solution in mind? Your expertise in this area would be greatly appreciated. Best Regards Hangbin
