From: Arnd Bergmann <arnd@xxxxxxxx>
The newly added NF_FLOW_TABLE options cause some build failures in
randconfig kernels:
- when CONFIG_NF_CONNTRACK is disabled, or is a loadable module but
NF_FLOW_TABLE is built-in:
In file included from net/netfilter/nf_flow_table.c:8:0:
include/net/netfilter/nf_conntrack.h:59:22: error: field 'ct_general' has incomplete type
struct nf_conntrack ct_general;

net/netfilter/nf_flow_table.o: In function `nf_flow_offload_work_gc':
(.text+0x1540): undefined reference to `nf_ct_delete'
- when CONFIG_NF_TABLES is disabled:
In file included from net/ipv6/netfilter/nf_flow_table_ipv6.c:13:0:
include/net/netfilter/nf_tables.h: In function 'nft_gencursor_next':
include/net/netfilter/nf_tables.h:1189:14: error: 'const struct net' has no member named 'nft'; did you mean 'nf'?
- when CONFIG_NF_FLOW_TABLE_INET is enabled, but NF_FLOW_TABLE_IPV4
or NF_FLOW_TABLE_IPV6 are not, or are loadable modules
net/netfilter/nf_flow_table_inet.o: In function `nf_flow_offload_inet_hook':
nf_flow_table_inet.c:(.text+0x94): undefined reference to `nf_flow_offload_ipv6_hook'
nf_flow_table_inet.c:(.text+0x40): undefined reference to `nf_flow_offload_ip_hook'
- when CONFIG_NF_FLOW_TABLES is disabled, but the other options are
enabled:
net/netfilter/nf_flow_table_inet.o: In function `nf_flow_offload_inet_hook':
nf_flow_table_inet.c:(.text+0x6c): undefined reference to `nf_flow_offload_ipv6_hook'
net/netfilter/nf_flow_table_inet.o: In function `nf_flow_inet_module_exit':

net/netfilter/nf_flow_table_inet.o: In function `nf_flow_inet_module_init':
nf_flow_table_inet.c:(.init.text+0x8): undefined reference to `nft_register_flowtable_type'
net/ipv4/netfilter/nf_flow_table_ipv4.o: In function `nf_flow_ipv4_module_exit':
nf_flow_table_ipv4.c:(.exit.text+0x8): undefined reference to `nft_unregister_flowtable_type'
net/ipv4/netfilter/nf_flow_table_ipv4.o: In function `nf_flow_ipv4_module_init':
nf_flow_table_ipv4.c:(.init.text+0x8): undefined reference to `nft_register_flowtable_type'
This adds additional Kconfig dependencies to ensure that NF_CONNTRACK and NF_TABLES
are always visible from NF_FLOW_TABLE, and that the internal dependencies between
the four new modules are met.
Fixes: 7c23b629a808 ("netfilter: flow table support for the mixed IPv4/IPv6 family")
Fixes: 0995210753a2 ("netfilter: flow table support for IPv6")
Fixes: 97add9f0d66d ("netfilter: flow table support for IPv4")
