netfilter: conntrack: fix IPV6=n builds
Stephen Rothwell reports:
After merging the netfilter-next tree, today's linux-next build
(powerpc ppc64_defconfig) failed like this:
ERROR: "nf_conntrack_invert_icmpv6_tuple" [nf_conntrack.ko] undefined!
ERROR: "nf_conntrack_icmpv6_packet" [nf_conntrack.ko] undefined!
ERROR: "nf_conntrack_icmpv6_init_net" [nf_conntrack.ko] undefined!
ERROR: "icmpv6_pkt_to_tuple" [nf_conntrack.ko] undefined!
ERROR: "nf_ct_gre_keymap_destroy" [nf_conntrack.ko] undefined!
icmpv6 related errors are due to lack of IS_ENABLED(CONFIG_IPV6) (no
icmpv6 support is builtin if kernel has CONFIG_IPV6=n), the
nf_ct_gre_keymap_destroy error is due to lack of PROTO_GRE check.
Fixes: a47c54048162 ("netfilter: conntrack: handle builtin l4proto packet functions via direct calls")
Fixes: e2e48b471634 ("netfilter: conntrack: handle icmp pkt_to_tuple helper via direct calls")
Fixes: 197c4300aec0 ("netfilter: conntrack: remove invert_tuple callback")
Fixes: 2a389de86e4a ("netfilter: conntrack: remove l4proto init and get_net callbacks")
Fixes: e56894356f60 ("netfilter: conntrack: remove l4proto destroy hook")
