From a58c38e4c579f409669b5ab82d3b039528a129af Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Fri, 7 Aug 2020 13:48:28 +0200 Subject: [PATCH] nft: Fix command name in ip6tables error message Upon errors, ip6tables-nft would prefix its error messages with 'iptables:' instead of 'ip6tables:'. Turns out the command name was hard-coded, use 'progname' variable instead. While being at it, merge the two mostly identical fprintf() calls into one.
