Subject: [iptables PATCH 01/12] ebtables: Fix error message for invalid parameters
Date: Sat, 20 Jul 2019 18:30:15 +0200 [thread overview]
Message-ID: <20190720163026.15410-2-phil@nwl.cc> (raw)
In-Reply-To: <20190720163026.15410-1-phil@nwl.cc>
With empty ruleset, ebtables-nft would report the wrong argv:
| % sudo ./install/sbin/ebtables-nft -vnL
| ebtables v1.8.3 (nf_tables): Unknown argument: './install/sbin/ebtables-nft'
| Try `ebtables -h' or 'ebtables --help' for more information.
After a (successful) call to 'ebtables-nft -L', this would even
segfault:
| % sudo ./install/sbin/ebtables-nft -vnL
| zsh: segmentation fault sudo ./install/sbin/ebtables-nft -vnL
Fixes: acde6be32036f ("ebtables-translate: Fix segfault while parsing extension options")
