From 1407a9c45350839073842bcc8c84ce524db3a119 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Fri, 4 Feb 2022 18:45:22 +0100 Subject: tests: iptables-test: Support variant deviation Some test results are not consistent between variants: * CLUSTERIP is not supported with nft_compat, so all related tests fail with iptables-nft. * iptables-legacy mandates TCPMSS be combined with SYN flag match, iptables-nft does not care. (Or precisely, xt_TCPMSS.ko can't validate match presence.) Introduce an optional fourth test spec field to specify the variant it applies to. Consequently, the opposite result is expected with the other variant.
