selftests/net: make so_txtime more robust to timer variance

2020-02-24T07:36:36+00:00

[ Upstream commit ea6a547669b37453f2b1a5d85188d75b3613dfaa ]

The SO_TXTIME test depends on accurate timers. In some virtualized
environments the test has been reported to be flaky. This is easily
reproduced by disabling kvm acceleration in Qemu.

Allow greater variance in a run and retry to further reduce flakiness.

Observed errors are one of two kinds: either the packet arrives too
early or late at recv(), or it was dropped in the qdisc itself and the
recv() call times out.

In the latter case, the qdisc queues a notification to the error
queue of the send socket. Also explicitly report this cause.

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

2020-01-17T18:48:20+00:00

commit cc7e3f63d7299dd1119be39aa187b867d6f8aa17 upstream.

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: net: tls: remove recv_rcvbuf test

2019-12-31T15:45:58+00:00

[ Upstream commit 6dd504b0fd1039c6e5d391e97cf5c4ee592aefcb ]

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.

selftests: net: Fix printf format warnings on arm

[ Upstream commit 670cd6849ea36ea4df2f2941cf4717dff8755abe ]

Fix printf format warnings on arm (and other 32bit arch).

 - udpgso.c and udpgso_bench_tx use %lu for size_t but it
   should be unsigned long long on 32bit arch.

 - so_txtime.c uses %ld for int64_t, but it should be
   unsigned long long on 32bit arch.

selftests: forwarding: Delete IPv6 address at the end

[ Upstream commit 65cb13986229cec02635a1ecbcd1e2dd18353201 ]

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 ]

Fix this by deleting the address during cleanup.

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

2019-12-04T21:31:04+00:00

[ Upstream commit 2745aea6750ff0d2c48285d25bdb00e5b636ec8b ]

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.
