commit 472caa69183f("netfilter: nat: un-export nf_nat_used_tuple")
introduce NF_NAT_MANIP_SRC/DST enum in include/net/netfilter/nf_nat.h,
and commit b06b45e82b59("selftests/bpf: add tests for bpf_ct_set_nat_info
kfunc") use NF_NAT_MANIP_SRC/DST in test_bpf_nf.c.
In bpf kself-test config (tools/testing/selftests/bpf/config) nf_nat
is compiled as built-in, this issue occurs just if it is compiled as
module. we just hardcode 1/0 here.
How to reproduce the error:
$ make -C tools/testing/selftests/bpf/
...
CLNG-BPF [test_maps] test_bpf_nf.bpf.o
error: use of undeclared identifier 'NF_NAT_MANIP_SRC'
bpf_ct_set_nat_info(ct, &saddr, sport, NF_NAT_MANIP_SRC);
^
error: use of undeclared identifier 'NF_NAT_MANIP_DST'
bpf_ct_set_nat_info(ct, &daddr, dport, NF_NAT_MANIP_DST);
^
