selftests: mptcp: interpret \n as a new line

2020-10-29T09:11:23+00:00

[ Upstream commit 8b974778f998ab1be23eca7436fc13d2d8c6bd59 ] In case of errors, this message was printed: (...) # read: Resource temporarily unavailable # client exit code 0, server 3 # \nnetns ns1-0-BJlt5D socket stat for 10003: (...) Obviously, the idea was to add a new line before the socket stat and not print "\nnetns".

selftests: rtnetlink: load fou module for kci_test_encap_fou() test

2020-10-29T09:10:55+00:00

[ Upstream commit 26ebd6fed9bb3aa480c7c0f147ac0e7b11000f65 ] The kci_test_encap_fou() test from kci_test_encap() in rtnetlink.sh needs the fou module to work. Otherwise it will fail with: $ ip netns exec "$testns" ip fou add port 7777 ipproto 47 RTNETLINK answers: No such file or directory Error talking to the kernel Add the CONFIG_NET_FOU into the config file as well. Which needs at least to be set as a loadable module.

selftests: forwarding: Add missing 'rp_filter' configuration

2020-10-29T09:10:55+00:00

[ Upstream commit 71a0e29e99405d89b695882d52eec60844173697 ] When 'rp_filter' is configured in strict mode (1) the tests fail because packets received from the macvlan netdevs would not be forwarded through them on the reverse path. Fix this by disabling the 'rp_filter', meaning no source validation is performed.

selftests: disable rp_filter for icmp_redirect.sh

2020-08-17T21:59:24+00:00

h1 is initially configured to reach h2 via r1 rather than the more direct path through r2. If rp_filter is set and inherited for r2, forwarding fails since the source address of h1 is reachable from eth0 vs the packet coming to it via r1 and eth1. Since rp_filter setting affects the test, explicitly reset it. Signed-off-by: David Ahern Signed-off-by: David S. Miller

mptcp: more stable diag self-tests

2020-08-08T00:25:38+00:00

During diag self-tests we introduce long wait in the mptcp test program to give the script enough time to access the sockets dump. Such wait is introduced after shutting down one sockets end. Since commit 43b54c6ee382 ("mptcp: Use full MPTCP-level disconnect state machine") if both sides shutdown the socket is correctly transitioned into CLOSED status. As a side effect some sockets are not dumped via the diag interface, because the socket state (CLOSED) does not match the default filter, and this cause self-tests instability. Address the issue moving the above mentioned wait before shutting down the socket.

selftests/net: relax cpu affinity requirement in msg_zerocopy test

2020-08-05T19:25:35+00:00

The msg_zerocopy test pins the sender and receiver threads to separate cores to reduce variance between runs. But it hardcodes the cores and skips core 0, so it fails on machines with the selected cores offline, or simply fewer cores. The test mainly gives code coverage in automated runs. The throughput of zerocopy ('-z') and non-zerocopy runs is logged for manual inspection. Continue even when sched_setaffinity fails. Just log to warn anyone interpreting the data.

selftests: rtnetlink: make kci_test_encap() return sub-test result

2020-08-05T19:23:29+00:00

kci_test_encap() is actually composed by two different sub-tests, kci_test_encap_vxlan() and kci_test_encap_fou() Therefore we should check the test result of these two in kci_test_encap() to let the script be aware of the pass / fail status. Otherwise it will generate false-negative result like below: $ sudo ./test.sh PASS: policy routing PASS: route get PASS: preferred_lft addresses have expired PASS: promote_secondaries complete PASS: tc htb hierarchy PASS: gre tunnel endpoint PASS: gretap PASS: ip6gretap PASS: erspan PASS: ip6erspan PASS: bridge setup PASS: ipv6 addrlabel PASS: set ifalias 5b193daf-0a08-46d7-af2c-e7aadd422ded for test-dummy0 PASS: vrf PASS: vxlan FAIL: can't add fou port 7777, skipping test PASS: macsec PASS: bridge fdb get PASS: neigh get $ echo $? 0 Signed-off-by: Po-Hsu Lin Signed-off-by: David S.

selftests: rtnetlink: correct the final return value for the test

2020-08-05T19:23:28+00:00

The return value "ret" will be reset to 0 from the beginning of each sub-test in rtnetlink.sh, therefore this test will always pass if the last sub-test has passed: $ sudo ./rtnetlink.sh PASS: policy routing PASS: route get PASS: preferred_lft addresses have expired PASS: promote_secondaries complete PASS: tc htb hierarchy PASS: gre tunnel endpoint PASS: gretap PASS: ip6gretap PASS: erspan PASS: ip6erspan PASS: bridge setup PASS: ipv6 addrlabel PASS: set ifalias a39ee707-e36b-41d3-802f-63179ed4d580 for test-dummy0 PASS: vrf PASS: vxlan FAIL: can't add fou port 7777, skipping test PASS: macsec PASS: ipsec 3,7c3,7 < sa[0] spi=0x00000009 proto=0x32 salt=0x64636261 crypt=1 < sa[0] key=0x31323334 35363738 39303132 33343536 < sa[1] rx ipaddr=0x00000000 00000000 00000000 c0a87b03 < sa[1] spi=0x00000009 proto=0x32 salt=0x64636261 crypt=1 < sa[1] key=0x31323334 35363738 39303132 33343536 --- > sa[0] spi=0x00000009 proto=0x32 salt=0x61626364 crypt=1 > sa[0] key=0x34333231 38373635 32313039 36353433 > sa[1] rx ipaddr=0x00000000 00000000 00000000 037ba8c0 > sa[1] spi=0x00000009 proto=0x32 salt=0x61626364 crypt=1 > sa[1] key=0x34333231 38373635 32313039 36353433 FAIL: ipsec_offload incorrect driver data FAIL: ipsec_offload PASS: bridge fdb get PASS: neigh get $ echo $? 0 Make "ret" become a local variable for all sub-tests.
