Hi all,
This patch series continues the work to migrate the script tests into prog_tests.
test_xdp_meta.sh uses the BPF programs defined in progs/test_xdp_meta.c to do a simple XDP/TC functional test that checks the metadata allocation performed by the bpf_xdp_adjust_meta() helper.
This is already partly covered by two tests under prog_tests/: - xdp_context_test_run.c uses bpf_prog_test_run_opts() to verify the validity of the xdp_md context after a call to bpf_xdp_adjust_meta() - xdp_metadata.c ensures that these meta-data can be exchanged through an AF_XDP socket.
However test_xdp_meta.sh also verifies that the meta-data initialized in the struct xdp_md is forwarded to the struct __sk_buff used by BPF programs at 'TC level'. To cover this, I add a test case in xdp_context_test_run.c that uses the same BPF programs from progs/test_xdp_meta.c.
