See5# mirror_gre_topo_lib.sh for more details.6#7# Test for "tc action mirred egress mirror" when the device to mirror to is a8# gretap or ip6gretap netdevice. Expect that the packets come out encapsulated,9# and another gretap / ip6gretap netdevice is then capable of decapsulating the10# traffic. Test that the payload is what is expected (ICMP ping request or11# reply, depending on test).12 13ALL_TESTS="14 test_gretap15 test_ip6gretap16 test_gretap_mac17 test_ip6gretap_mac18 test_two_spans19"20 21NUM_NETIFS=622source lib.sh23source mirror_lib.sh24source mirror_gre_lib.sh25source mirror_gre_topo_lib.sh26 27setup_prepare()28{29 h1=${NETIFS[p1]}30 swp1=${NETIFS[p2]}31 32 swp2=${NETIFS[p3]}33 h2=${NETIFS[p4]}34 35 swp3=${NETIFS[p5]}36 h3=${NETIFS[p6]}37 38 vrf_prepare39 mirror_gre_topo_create40 41 ip address add dev $swp3 192.0.2.129/2842 ip address add dev $h3 192.0.2.130/2843 44 ip address add dev $swp3 2001:db8:2::1/6445 ip address add dev $h3 2001:db8:2::2/6446}47 48cleanup()49{50 pre_cleanup51 52 ip address del dev $h3 2001:db8:2::2/6453 ip address del dev $swp3 2001:db8:2::1/6454 55 ip address del dev $h3 192.0.2.130/2856 ip address del dev $swp3 192.0.2.129/2857 58 mirror_gre_topo_destroy59 vrf_cleanup60}61 62test_span_gre_mac()63{64 local tundev=$1; shift65 local direction=$1; shift66 local what=$1; shift67 68 case "$direction" in69 ingress) local src_mac=$(mac_get $h1); local dst_mac=$(mac_get $h2)70 ;;71 egress) local src_mac=$(mac_get $h2); local dst_mac=$(mac_get $h1)72 ;;73 esac74 75 RET=076 77 mirror_install $swp1 $direction $tundev "matchall"78 icmp_capture_install h3-${tundev} "src_mac $src_mac dst_mac $dst_mac"79 80 mirror_test v$h1 192.0.2.1 192.0.2.2 h3-${tundev} 100 1081 82 icmp_capture_uninstall h3-${tundev}83 mirror_uninstall $swp1 $direction84 85 log_test "$direction $what: envelope MAC"86}87 88test_two_spans()89{90 RET=091 92 mirror_install $swp1 ingress gt4 "matchall"93 mirror_install $swp1 egress gt6 "matchall"94 quick_test_span_gre_dir gt4 8 095 quick_test_span_gre_dir gt6 0 896 97 mirror_uninstall $swp1 ingress98 fail_test_span_gre_dir gt4 8 099 quick_test_span_gre_dir gt6 0 8100 101 mirror_install $swp1 ingress gt4 "matchall"102 mirror_uninstall $swp1 egress103 quick_test_span_gre_dir gt4 8 0104 fail_test_span_gre_dir gt6 0 8105 106 mirror_uninstall $swp1 ingress107 log_test "two simultaneously configured mirrors"108}109 110test_gretap()111{112 full_test_span_gre_dir gt4 ingress 8 0 "mirror to gretap"113 full_test_span_gre_dir gt4 egress 0 8 "mirror to gretap"114}115 116test_ip6gretap()117{118 full_test_span_gre_dir gt6 ingress 8 0 "mirror to ip6gretap"119 full_test_span_gre_dir gt6 egress 0 8 "mirror to ip6gretap"120}121 122test_gretap_mac()123{124 test_span_gre_mac gt4 ingress "mirror to gretap"125 test_span_gre_mac gt4 egress "mirror to gretap"126}127 128test_ip6gretap_mac()129{130 test_span_gre_mac gt6 ingress "mirror to ip6gretap"131 test_span_gre_mac gt6 egress "mirror to ip6gretap"132}133 134trap cleanup EXIT135 136setup_prepare137setup_wait138 139tests_run140 141exit $EXIT_STATUS142
