From 35b22e82fa62e10950d8e0fa53a755d4abadf346 Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Tue, 5 Feb 2019 18:18:02 +0100 Subject: Revert "ebtables: use extrapositioned negation consistently" This reverts commit 5f508b76a0cebaf91965ffa678089222e2d47964. While attempts at unifying syntax between arp-, eb- and iptables-nft increase the opportunity for more code-sharing, they are problematic when it comes to compatibility. Accepting the old syntax on input helps, but due to the fact that neither arptables nor ebtables support --check command we must expect for users to test existence of a rule by comparing input with output. If that happens in a script, deviating from the old syntax in output has a high chance of breaking it. Therefore revert Florian's patch changing inversion character position in output and review the old code for consistency - the only thing changed on top of the actual revert is ebtables' own copy of print_iface() to make it adhere to the intrapositioned negation scheme used throughout ebtables. Added extension tests by the reverted commit have been kept.
