selftests: loopback.sh: skip this test if the driver does not support

2020-01-03T20:23:34Z

The loopback feature is only supported on a few drivers like broadcom, mellanox, etc. The default veth driver has not supported it yet. To avoid returning failed and making the runner feel confused, let's just skip the test on drivers that not support loopback.

selftests: pmtu: fix init mtu value in description

2019-12-21T05:52:21Z

There is no a_r3, a_r4 in the testing topology. It should be b_r1, b_r2. Also b_r1 mtu is 1400 and b_r2 mtu is 1500. Fixes: e44e428f59e4 ("selftests: pmtu: add basic IPv4 and IPv6 PMTU tests") Signed-off-by: Hangbin Liu Acked-by: Stefano Brivio Signed-off-by: David S. Miller

selftests: net: tls: remove recv_rcvbuf test

2019-12-15T03:53:53Z

This test only works when [1] is applied, which was rejected. Basically, the errors are reported and cleared. In this particular case of tls sockets, following reads will block. The test case was originally submitted with the rejected patch, but, then, was included as part of a different patchset, possibly by mistake. [1] https://lore.kernel.org/netdev/20191007035323.4360-2-jakub.kicinski@netronome.com/#t Thanks Paolo Pisati for pointing out the original patchset where this appeared.

selftests: forwarding: Delete IPv6 address at the end

2019-12-09T18:19:45Z

When creating the second host in h2_create(), two addresses are assigned to the interface, but only one is deleted. When running the test twice in a row the following error is observed: $ ./router_bridge_vlan.sh TEST: ping [ OK ] TEST: ping6 [ OK ] TEST: vlan [ OK ] $ ./router_bridge_vlan.sh RTNETLINK answers: File exists TEST: ping [ OK ] TEST: ping6 [ OK ] TEST: vlan [ OK ] Fix this by deleting the address during cleanup.

selftests: forwarding: fix race between packet receive and tc check

2019-11-30T20:23:27Z

It is possible that tc stats get checked before the packet we check for actually arrived into the interface and accounted for. Fix it by checking for the expected result in a loop until timeout is reached (by default 1 second).

selftests: pmtu: use -oneline for ip route list cache

2019-11-29T20:29:55Z

Some versions of iproute2 will output more than one line per entry, which will cause the test to fail, like: TEST: ipv6: list and flush cached exceptions [FAIL] can't list cached exceptions That happens, for example, with iproute2 4.15.0. When using the -oneline option, this will work just fine: TEST: ipv6: list and flush cached exceptions [ OK ] This also works just fine with a more recent version of iproute2, like 5.4.0. For some reason, two lines are printed for the IPv4 test no matter what version of iproute2 is used. Use the same -oneline parameter there instead of counting the lines twice.
