Subject: [PATCH nf-next 00/12] netfilter: remove xtables pointers from struct net
Date: Tue, 20 Apr 2021 14:24:55 +0200 [thread overview]
Message-ID: <20210420122507.505-1-fw@strlen.de> (raw)
This change removes all xt_table pointers from struct net.
The various ip(6)table_foo incarnations are updated to expect
that the table is passed as 'void *priv' argument that netfilter core
passes to the hook functions.
This reduces the struct net size by 2 cachelines on x86_64.
Florian Westphal (12):
netfilter: ebtables: remove the 3 ebtables pointers from struct net
netfilter: x_tables: remove ipt_unregister_table
netfilter: add xt_find_table
netfilter: iptables: unregister the tables by name
netfilter: ip6tables: unregister the tables by name
netfilter: arptables: unregister the tables by name
netfilter: x_tables: remove paranoia tests
netfilter: xt_nat: pass table to hookfn
netfilter: ip_tables: pass table pointer via nf_hook_ops
netfilter: arp_tables: pass table pointer via nf_hook_ops
netfilter: ip6_tables: pass table pointer via nf_hook_ops
netfilter: remove all xt_table anchors from struct net
