From: Rong Tao <rongtao@cestc.cn>
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 could use BPF CO-RE and ___suffix rule to avoid this.
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);
^
2 errors generated.

Agreed. bpf_core_enum_value_exists() makes no sense here. bpf_core_enum_value(enum nf_nat_manip_type___x, NF_NAT_MANIP_SRC___x) would be ok, IMHO. It will compile but fail at runtime if the module is not loaded. > > > > /* dnat */ > > daddr.ip = bpf_get_prandom_u32(); > > - bpf_ct_set_nat_info(ct, &daddr, dport, NF_NAT_MANIP_DST); > > + bpf_ct_set_nat_info(ct, &daddr, dport, manip_dst); > > > > ct_ins = bpf_ct_insert_entry(ct); > > if (ct_ins) { > > -- > > 2.31.1 > > ^ permalink raw reply [flat|nested] 5+ messages in thread

Would be better to fix the test properly instead of just papering over the compilation issue like this. That requires a bit more surgery to the selftests, though... -Toke [0] https://lore.kernel.org/r/87leoh372s.fsf@toke.dk ^ permalink raw reply [flat|nested] 5+ messages in thread
