Hi all, Today's linux-next merge of the net-next tree got a conflict in: tools/testing/selftests/net/mptcp/mptcp_join.sh between commit: 6ef84b1517e08 ("selftests: mptcp: more robust signal race test") from the net tree and commit: 34aa6e3bccd86 ("selftests: mptcp: add ip mptcp wrappers") from the net-next tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. diff --cc tools/testing/selftests/net/mptcp/mptcp_join.sh index 0c8a2a20b96cf,725924012b412..0000000000000 --- a/tools/testing/selftests/net/mptcp/mptcp_join.sh +++ b/tools/testing/selftests/net/mptcp/mptcp_join.sh @@@ -1163,20 -1287,17 +1302,21 @@@ signal_address_tests( # signal addresses race test reset - ip netns exec $ns1 ./pm_nl_ctl limits 4 4 - ip netns exec $ns2 ./pm_nl_ctl limits 4 4 - ip netns exec $ns1 ./pm_nl_ctl add 10.0.1.1 flags signal - ip netns exec $ns1 ./pm_nl_ctl add 10.0.2.1 flags signal - ip netns exec $ns1 ./pm_nl_ctl add 10.0.3.1 flags signal - ip netns exec $ns1 ./pm_nl_ctl add 10.0.4.1 flags signal - ip netns exec $ns2 ./pm_nl_ctl add 10.0.1.2 flags signal - ip netns exec $ns2 ./pm_nl_ctl add 10.0.2.2 flags signal - ip netns exec $ns2 ./pm_nl_ctl add 10.0.3.2 flags signal - ip netns exec $ns2 ./pm_nl_ctl add 10.0.4.2 flags signal ++ + pm_nl_set_limits $ns1 4 4 + pm_nl_set_limits $ns2 4 4 + pm_nl_add_endpoint $ns1 10.0.1.1 flags signal + pm_nl_add_endpoint $ns1 10.0.2.1 flags signal + pm_nl_add_endpoint $ns1 10.0.3.1 flags signal + pm_nl_add_endpoint $ns1 10.0.4.1 flags signal + pm_nl_add_endpoint $ns2 10.0.1.2 flags signal + pm_nl_add_endpoint $ns2 10.0.2.2 flags signal + pm_nl_add_endpoint $ns2 10.0.3.2 flags signal + pm_nl_add_endpoint $ns2 10.0.4.2 flags signal - run_tests $ns1 $ns2 10.0.1.1 + + # the peer could possibly miss some addr notification, allow retransmission + ip netns exec $ns1 sysctl -q net.mptcp.add_addr_timeout=1 + run_tests $ns1 $ns2 10.0.1.1 0 0 0 slow chk_join_nr "signal addresses race test" 3 3 3 # the server will not signal the address terminating
