The patch series have been tested by enabling iptables and ip6tables SYNPROXY.
All the modules loaded as expected.
$ lsmod | grep synproxy
Only IPv4:
ipt_SYNPROXY 16384 1
nf_synproxy_core 24576 1 ipt_SYNPROXY
nf_conntrack 159744 5 xt_conntrack,xt_state,ipt_SYNPROXY,nf_synproxy_core,xt_CT
x_tables 49152 7 xt_conntrack,nft_compat,xt_state,xt_tcpudp,ipt_SYNPROXY,xt_CT,ip_tables
Only IPv6:
ip6t_SYNPROXY 16384 1
nf_synproxy_core 24576 1 ip6t_SYNPROXY
nf_conntrack 159744 4 ip6t_SYNPROXY,xt_conntrack,xt_state,nf_synproxy_core
x_tables 49152 6 ip6t_SYNPROXY,xt_conntrack,nft_compat,xt_state,xt_tcpudp,ip_tables
IPv4 and IPv6:
ip6t_SYNPROXY 16384 1
ipt_SYNPROXY 16384 1
nf_synproxy_core 24576 2 ip6t_SYNPROXY,ipt_SYNPROXY
nf_conntrack 159744 6 ip6t_SYNPROXY,xt_conntrack,xt_state,ipt_SYNPROXY,nf_synproxy_core,xt_CT
x_tables 49152 8 ip6t_SYNPROXY,xt_conntrack,nft_compat,xt_state,xt_tcpudp,ipt_SYNPROXY,xt_CT,ip_tables
v1: Initial patch
v2: Unify nf_synproxy_ipv4 and nf_synproxy_ipv6 into nf_synproxy
v3: Remove synproxy_cookie dependency
v4: Remove another synproxy_cookie, unify nf_synproxy into nf_synproxy_core so now we are using a single module.
Fernando Fernandez Mancera (3):
netfilter: synproxy: add common uapi for SYNPROXY infrastructure
netfilter: synproxy: remove module dependency on IPv6 SYNPROXY
netfilter: synproxy: extract SYNPROXY infrastructure from
{ipt,ip6t}_SYNPROXY
