Hangbin Liu d232924762 selftests/bpf: Add xdp_redirect_multi test ... Add a bpf selftest for new helper xdp_redirect_map_multi(). In this test there are 3 forward groups and 1 exclude group. The test will redirect each interface's packets to all the interfaces in the forward group, and exclude the interface in exclude map. Two maps (DEVMAP, DEVMAP_HASH) and two xdp modes (generic, drive) will be tested. XDP egress program will also be tested by setting pkt src MAC to egress interface's MAC address. For more test details, you can find it in the test script. Here is the test result. ]# time ./test_xdp_redirect_multi.sh Pass: xdpgeneric arp(F_BROADCAST) ns1-1 Pass: xdpgeneric arp(F_BROADCAST) ns1-2 Pass: xdpgeneric arp(F_BROADCAST) ns1-3 Pass: xdpgeneric IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-1 Pass: xdpgeneric IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-2 Pass: xdpgeneric IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-3 Pass: xdpgeneric IPv6 (no flags) ns1-1 Pass: xdpgeneric IPv6 (no flags) ns1-2 Pass: xdpdrv arp(F_BROADCAST) ns1-1 Pass: xdpdrv arp(F_BROADCAST) ns1-2 Pass: xdpdrv arp(F_BROADCAST) ns1-3 Pass: xdpdrv IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-1 Pass: xdpdrv IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-2 Pass: xdpdrv IPv4 (F_BROADCAST|F_EXCLUDE_INGRESS) ns1-3 Pass: xdpdrv IPv6 (no flags) ns1-1 Pass: xdpdrv IPv6 (no flags) ns1-2 Pass: xdpegress mac ns1-2 Pass: xdpegress mac ns1-3 Summary: PASS 18, FAIL 0 real 1m18.321s user 0m0.123s sys 0m0.350s Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Toke Høiland-Jørgensen <toke@redhat.com> Link: https://lore.kernel.org/bpf/20210519090747.1655268-5-liuhangbin@gmail.com		2021-05-26 09:46:16 +02:00
