Subject: [PATCH nf-next 0/3] netfilter: clusterip: don't register hook in all netns
Date: Thu, 22 Jul 2021 10:48:31 +0200 [thread overview]
Message-ID: <20210722084834.27027-1-fw@strlen.de> (raw)
This series stops ipt_CLUSTERIP from registering arp mangling hook
unconditionally.
Hook gets installed/removed from checkentry/destroy callbacks.
Before this, modprobe ipt_CLUSTERIP would add a hook in each netns.
While at it, also get rid of x_tables.h/xt storage space in struct net,
there is no need for this.
Florian Westphal (3):
netfilter: ipt_CLUSTERIP: only add arp mangle hook when required
netfilter: ipt_CLUSTERIP: use clusterip_net to store pernet warning
netfilter: remove xt pernet data
