[PATCH bpf-next 0/2] selftests: bpf: Migrate test_xdp_meta.sh to test_progs

[Bastien Curutchet]

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.
