Hi everyone There seems to be some issue with BTF mismatch when trying to run the bpf_ct_set_nat_info() kfunc from a module. I was under the impression that this is supposed to work, so is there some kind of BTF dedup issue here or something? Steps to reproduce: 1. Compile kernel with nf_conntrack built-in and run selftests; './test_progs -a bpf_nf' works 2. Change the kernel config so nf_conntrack is build as a module 3. Start the test kernel and manually modprobe nf_conntrack and nf_nat 4. Run ./test_progs -a bpf_nf; this now fails with an error like: kernel function bpf_ct_set_nat_info args#0 expected pointer to STRUCT nf_conn___init but R1 has a pointer to STRUCT nf_conn___init Anyone has any ideas what's going on here, and how to fix it? -Toke
