Subject: [iptables PATCH 01/23] libxtables: xtoptions: Prevent XTOPT_PUT with XTTYPE_HOSTMASK
Date: Wed, 20 Dec 2023 17:06:14 +0100 [thread overview]
Message-ID: <20231220160636.11778-2-phil@nwl.cc> (raw)
In-Reply-To: <20231220160636.11778-1-phil@nwl.cc>
Do as the comment in xtopt_parse_hostmask() claims and omit
XTTYPE_HOSTMASK from xtopt_psize array so xtables_option_metavalidate()
will catch the incompatibility.
Fixes: 66266abd17adc ("libxtables: XTTYPE_HOSTMASK support")
Signed-off-by: Phil Sutter <phil@nwl.cc>
