This test fails on current kernel releases because the flotwable path now calls dst_check from packet path and will then remove the offload. Test script has two purposes: 1. check that file (random content) can be sent to other netns (and vv) 2. check that the flow is offloaded (rather than handled by classic forwarding path). Since dst_check is in place, 2) fails because the nftables ruleset in router namespace 1 intentionally blocks traffic under the assumption that packets are not passed via classic path at all. Rework this: Instead of blocking traffic, create two named counters, one for original and one for reverse direction. The first three test cases are handled by classic forwarding path (path mtu discovery is disabled and packets exceed MTU). But all other tests enable PMTUD, so the originator and responder are expected to lower packet size and flowtable is expected to do the packet forwarding. For those tests, check that the packet counters (which are only incremented for packets that are passed up to classic forward path) are significantly lower than the file size transferred. I've tested that the counter-checks fail as expected when the 'flow add' statement is removed from the ruleset. Signed-off-by: Florian Westphal <fw@strlen.de> |
