[PATCH bpf-next v2 00/10] selftests/bpf: Migrate test_xdp_redirect_multi.sh to test_progs

[Bastien Curutchet (eBPF Foundation)]

Hi all,

This patch series continues the work to migrate the *.sh tests into
prog_tests framework.

test_xdp_redirect_multi.sh tests the XDP redirections done through
bpf_redirect_map().

This is already partly covered by test_xdp_veth.c that already tests
map redirections at XDP level. What isn't covered yet by test_xdp_veth is
the use of the broadcast flags (BPF_F_BROADCAST or BPF_F_EXCLUDE_INGRESS)
and XDP egress programs.

Hence, this patch series add test cases to test_xdp_veth.c to get rid of
the test_xdp_redirect_multi.sh:
 - PATCH 1 to 5 rework test_xdp_veth to make it more generic and allow to
   configure different test cases
 - PATCH 6 adds test cases for 'classic' bpf_redirect_map()
 - PATCH 7 & 8 covers the broadcast flags
 - PATCH 9 covers the XDP egress programs
 - PATCH 10 removes test_xdp_redirect_multi.sh
