2022-09-21selftests/bpf: add tests for bpf_ct_set_nat_info kfuncLorenzo Bianconi1-3/+7
Introduce self-tests for bpf_ct_set_nat_info kfunc used to set the source or destination nat addresses/ports. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Link: https://lore.kernel.org/r/803e33294e247744d466943105879414344d3235.1663778601.git.lorenzo@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2022-09-10selftests/bpf: fix ct status check in bpf_nf selftestsLorenzo Bianconi1-2/+3
Check properly the connection tracking entry status configured running bpf_ct_change_status kfunc. Remove unnecessary IPS_CONFIRMED status configuration since it is already done during entry allocation.

2022-09-10selftests/bpf: Add tests for writing to nf_conn:markDaniel Xu1-0/+2
Add a simple extension to the existing selftest to write to nf_conn:mark. Also add a failure test for writing to unsupported field.

2022-08-15selftests/bpf: Add connmark read testDaniel Xu1-1/+2
Test that the prog can read from the connection mark. This test is nice because it ensures progs can interact with netfilter subsystem correctly.

2022-08-15selftests/bpf: Add existing connection bpf_*_ct_lookup() testDaniel Xu1-0/+59
Add a test where we do a conntrack lookup on an existing connection. This is nice because it's a more realistic test than artifically creating a ct entry and looking it up afterwards.

2022-07-21selftests/bpf: Add negative tests for new nf_conntrack kfuncsKumar Kartikeya Dwivedi1-1/+55
Test cases we care about and ensure improper usage is caught and rejected by the verifier. Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/r/20220721134245.2450-13-memxor@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2022-07-21selftests/bpf: Add tests for new nf_conntrack kfuncsLorenzo Bianconi1-0/+8
Introduce selftests for the following kfunc helpers: - bpf_xdp_ct_alloc - bpf_skb_ct_alloc - bpf_ct_insert_entry - bpf_ct_set_timeout - bpf_ct_change_timeout - bpf_ct_set_status - bpf_ct_change_status Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/r/20220721134245.2450-12-memxor@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
2022-02-02selftests/bpf: Migrate from bpf_prog_test_runDelyan Kratunov1-3/+7
bpf_prog_test_run is being deprecated in favor of the OPTS-based bpf_prog_test_run_opts. We end up unable to use CHECK in most cases, so replace usages with ASSERT_* calls.

2022-01-18selftests/bpf: Add test for unstable CT lookup APIKumar Kartikeya Dwivedi1-0/+48
This tests that we return errors as documented, and also that the kfunc calls work from both XDP and TC hooks. Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/r/20220114163953.1455836-8-memxor@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
