Hello, this series aims to bring test_tcp_check_syncookie.sh scope into test_progs to make sure that the corresponding tests are also run automatically in CI. This script tests for bpf_tcp_{gen,check}_syncookie and bpf_skc_lookup_tcp, in different contexts (ipv4, v6 or dual, and with tc and xdp programs). Some other tests like btf_skc_cls_ingress have some overlapping tests with test_tcp_check_syncookie.sh, so this series moves the missing bits from test_tcp_check_syncookie.sh into btf_skc_cls_ingress, which is already integrated into test_progs. - the first three commits bring some minor improvements to btf_skc_cls_ingress without changing its testing scope - fourth and fifth commits bring test_tcp_check_syncookie.sh features into btf_skc_cls_ingress - last commit removes test_tcp_check_syncookie.sh
The only topic for which I am not sure for this integration is the necessity or not to run the tests with different program types: test_tcp_check_syncookie.sh runs tests with both tc and xdp programs, but btf_skc_cls_ingress currently tests those helpers only with a tc program. Would it make sense to also make sure that btf_skc_cls_ingress is tested with all the programs types supported by those helpers ?
The series has been tested both in CI and in a local x86_64 qemu environment: # ./test_progs -a btf_skc_cls_ingress #38/1 btf_skc_cls_ingress/conn_ipv4:OK #38/2 btf_skc_cls_ingress/conn_ipv6:OK #38/3 btf_skc_cls_ingress/conn_dual:OK #38/4 btf_skc_cls_ingress/syncookie_ipv4:OK #38/5 btf_skc_cls_ingress/syncookie_ipv6:OK #38/6 btf_skc_cls_ingress/syncookie_dual:OK #38 btf_skc_cls_ingress:OK Summary: 1/6 PASSED, 0 SKIPPED, 0 FAILED
