Exercise the drop action in the datapath. This specific tests triggers an xlate_error.
For the kernel datapath skb drop reasons can then be seen while this test runs. # perf trace -e skb:kfree_skb --filter="reason >= 0x30000" 0.000 ping/1275884 skb:kfree_skb(skbaddr: 0xffff8acd76546000, \ location: 0xffffffffc0ee3634, protocol: 2048, reason: 196611) Acked-by: Eelco Chaudron <echau...@redhat.com> Signed-off-by: Eric Garver <e...@garver.life> --- tests/system-common-macros.at | 4 ++++ tests/system-traffic.at | 31 +++++++++++++++++++++++++++++++ 2 files changed, 35 insertions(+) diff --git a/tests/system-common-macros.at b/tests/system-common-macros.at index 01ebe364ee7c..2a68cd664e5c 100644 --- a/tests/system-common-macros.at +++ b/tests/system-common-macros.at @@ -374,3 +374,7 @@ m4_define([OVS_CHECK_CT_CLEAR], # OVS_CHECK_GITHUB_ACTION m4_define([OVS_CHECK_GITHUB_ACTION], [AT_SKIP_IF([test "$GITHUB_ACTIONS" = "true"])]) + +# OVS_CHECK_DROP_ACTION() +m4_define([OVS_CHECK_DROP_ACTION], + [AT_SKIP_IF([! grep -q "Datapath supports explicit drop action" ovs-vswitchd.log])]) diff --git a/tests/system-traffic.at b/tests/system-traffic.at index 2d12d558ec2f..cc0d294a0525 100644 --- a/tests/system-traffic.at +++ b/tests/system-traffic.at @@ -2231,6 +2231,37 @@ masks-cache:size:256 OVS_TRAFFIC_VSWITCHD_STOP AT_CLEANUP +AT_SETUP([datapath - drop action]) +OVS_TRAFFIC_VSWITCHD_START() +OVS_CHECK_DROP_ACTION() +AT_KEYWORDS(drop_action) + +ADD_NAMESPACES(at_ns0, at_ns1) + +ADD_VETH(p0, at_ns0, br0, "10.1.1.1/24") +ADD_VETH(p1, at_ns1, br0, "10.1.1.2/24") + +dnl Exceed the max number of resubmits. +(echo "dl_type=0x806, actions=normal" +for i in `seq 1 64`; do + j=`expr $i + 1` + echo "in_port=$i, actions=resubmit:$j, resubmit:$j, local" + done + echo "in_port=65, actions=local" +) > flows.txt +AT_CHECK([ovs-ofctl add-flows br0 flows.txt]) + +dnl Generate some traffic. +NS_CHECK_EXEC([at_ns0], [ping -q -c 10 -i 0.1 -w 2 10.1.1.2], [1], [ignore]) + +OVS_WAIT_UNTIL_EQUAL([ovs-appctl dpctl/dump-flows | grep "eth_type(0x0800)" | dnl + strip_ptype | strip_eth | strip_recirc | strip_stats | dnl + strip_used | sort], [dnl +recirc_id(<recirc>),in_port(2),eth_type(0x0800),ipv4(frag=no), packets:0, bytes:0, used:0.0s, actions:drop]) + +OVS_TRAFFIC_VSWITCHD_STOP(["/|WARN|/d"]) +AT_CLEANUP + AT_SETUP([datapath - simulated flow action update]) OVS_TRAFFIC_VSWITCHD_START() -- 2.43.0 _______________________________________________ dev mailing list d...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-dev
