Author: kp Date: Mon Jun 1 19:26:16 2020 New Revision: 361701 URL: https://svnweb.freebsd.org/changeset/base/361701 Log: bridge tests: Avoid building a switching loop Enable STP before bringing the bridges up. This avoids a switching loop, which has a tendency to drown out progress in userspace processes, especially on single-core systems. Only check that we have indeed shut down one of the looped interfaces PR: 246448 Reviewed by: melifaro Differential Revision: https://reviews.freebsd.org/D25084 Modified: head/tests/sys/net/if_bridge_test.sh Modified: head/tests/sys/net/if_bridge_test.sh ============================================================================== --- head/tests/sys/net/if_bridge_test.sh Mon Jun 1 18:58:09 2020 (r361700) +++ head/tests/sys/net/if_bridge_test.sh Mon Jun 1 19:26:16 2020 (r361701) @@ -72,7 +72,6 @@ stp_head() { atf_set descr 'Spanning tree test' atf_set require.user root - atf_set require.progs jq } stp_body() @@ -91,13 +90,11 @@ stp_body() vnet_mkjail a ${bridge_a} ${epair_one}a ${epair_two}a vnet_mkjail b ${bridge_b} ${epair_one}b ${epair_two}b - jexec a ifconfig ${bridge_a} up jexec a ifconfig ${epair_one}a up jexec a ifconfig ${epair_two}a up jexec a ifconfig ${bridge_a} addm ${epair_one}a jexec a ifconfig ${bridge_a} addm ${epair_two}a - jexec b ifconfig ${bridge_b} up jexec b ifconfig ${epair_one}b up jexec b ifconfig ${epair_two}b up jexec b ifconfig ${bridge_b} addm ${epair_one}b @@ -105,22 +102,14 @@ stp_body() jexec a ifconfig ${bridge_a} 192.0.2.1/24 - # Give the interfaces some time to come up and pass some traffic - sleep 5 - - # Confirm that there's looping traffic - nbr=$(jexec a netstat -I ${bridge_a} --libxo json \ - | jq ".statistics.interface[0].\"received-packets\"") - if [ ${nbr} -lt 100 ] - then - atf_fail "Expected bridging loop, but found very few packets." - fi - # Enable spanning tree jexec a ifconfig ${bridge_a} stp ${epair_one}a jexec a ifconfig ${bridge_a} stp ${epair_two}a jexec b ifconfig ${bridge_b} stp ${epair_one}b jexec b ifconfig ${bridge_b} stp ${epair_two}b + + jexec b ifconfig ${bridge_b} up + jexec a ifconfig ${bridge_a} up # Give STP time to do its thing sleep 5
