See 5# mirror_gre_topo_lib.sh for more details. 6# 7# Test for "tc action mirred egress mirror" when the device to mirror to is a 8# gretap or ip6gretap netdevice. Expect that the packets come out encapsulated, 9# and another gretap / ip6gretap netdevice is then capable of decapsulating the 10# traffic. Test that the payload is what is expected (ICMP ping request or 11# reply, depending on test). 12 13ALL_TESTS=" 14 test_gretap 15 test_ip6gretap 16 test_gretap_mac 17 test_ip6gretap_mac 18 test_two_spans 19" 20 21NUM_NETIFS=6 22source lib.sh 23source mirror_lib.sh 24source mirror_gre_lib.sh 25source mirror_gre_topo_lib.sh 26 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_prepare 39 mirror_gre_topo_create 40 41 ip address add dev $swp3 192.0.2.129/28 42 ip address add dev $h3 192.0.2.130/28 43 44 ip address add dev $swp3 2001:db8:2::1/64 45 ip address add dev $h3 2001:db8:2::2/64 46} 47 48cleanup() 49{ 50 pre_cleanup 51 52 ip address del dev $h3 2001:db8:2::2/64 53 ip address del dev $swp3 2001:db8:2::1/64 54 55 ip address del dev $h3 192.0.2.130/28 56 ip address del dev $swp3 192.0.2.129/28 57 58 mirror_gre_topo_destroy 59 vrf_cleanup 60} 61 62test_span_gre_mac() 63{ 64 local tundev=$1; shift 65 local direction=$1; shift 66 local prot=$1; shift 67 local what=$1; shift 68 69 local swp3mac=$(mac_get $swp3) 70 local h3mac=$(mac_get $h3) 71 72 RET=0 73 74 mirror_install $swp1 $direction $tundev "matchall $tcflags" 75 tc qdisc add dev $h3 clsact 76 tc filter add dev $h3 ingress pref 77 prot $prot \ 77 flower ip_proto 0x2f src_mac $swp3mac dst_mac $h3mac \ 78 action pass 79 80 mirror_test v$h1 192.0.2.1 192.0.2.2 $h3 77 10 81 82 tc filter del dev $h3 ingress pref 77 83 tc qdisc del dev $h3 clsact 84 mirror_uninstall $swp1 $direction 85 86 log_test "$direction $what: envelope MAC ($tcflags)" 87} 88 89test_two_spans() 90{ 91 RET=0 92 93 mirror_install $swp1 ingress gt4 "matchall $tcflags" 94 mirror_install $swp1 egress gt6 "matchall $tcflags" 95 quick_test_span_gre_dir gt4 ingress 96 quick_test_span_gre_dir gt6 egress 97 98 mirror_uninstall $swp1 ingress 99 fail_test_span_gre_dir gt4 ingress 100 quick_test_span_gre_dir gt6 egress 101 102 mirror_install $swp1 ingress gt4 "matchall $tcflags" 103 mirror_uninstall $swp1 egress 104 quick_test_span_gre_dir gt4 ingress 105 fail_test_span_gre_dir gt6 egress 106 107 mirror_uninstall $swp1 ingress 108 log_test "two simultaneously configured mirrors ($tcflags)" 109} 110 111test_gretap() 112{ 113 full_test_span_gre_dir gt4 ingress 8 0 "mirror to gretap" 114 full_test_span_gre_dir gt4 egress 0 8 "mirror to gretap" 115} 116 117test_ip6gretap() 118{ 119 full_test_span_gre_dir gt6 ingress 8 0 "mirror to ip6gretap" 120 full_test_span_gre_dir gt6 egress 0 8 "mirror to ip6gretap" 121} 122 123test_gretap_mac() 124{ 125 test_span_gre_mac gt4 ingress ip "mirror to gretap" 126 test_span_gre_mac gt4 egress ip "mirror to gretap" 127} 128 129test_ip6gretap_mac() 130{ 131 test_span_gre_mac gt6 ingress ipv6 "mirror to ip6gretap" 132 test_span_gre_mac gt6 egress ipv6 "mirror to ip6gretap" 133} 134 135test_all() 136{ 137 slow_path_trap_install $swp1 ingress 138 slow_path_trap_install $swp1 egress 139 140 tests_run 141 142 slow_path_trap_uninstall $swp1 egress 143 slow_path_trap_uninstall $swp1 ingress 144} 145 146trap cleanup EXIT 147 148setup_prepare 149setup_wait 150 151tcflags="skip_hw" 152test_all 153 154if ! tc_offload_check; then 155 echo "WARN: Could not test offloaded functionality" 156else 157 tcflags="skip_sw" 158 test_all 159fi 160 161exit $EXIT_STATUS 162
