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

2019-12-04T21:34:28+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.

selftests/tls: add a test for fragmented messages

2019-12-04T21:34:24+00:00

[ Upstream commit 65190f77424d7b82c4aad7326c9cce6bd91a2fcc ]

Add a sendmsg test with very fragmented messages. This should
fill up sk_msg and test the boundary conditions.

selftests: net: reuseport_dualstack: fix uninitalized parameter

[ Upstream commit d64479a3e3f9924074ca7b50bd72fa5211dca9c1 ]

This test reports EINVAL for getsockopt(SOL_SOCKET, SO_DOMAIN)
occasionally due to the uninitialized length parameter.
Initialize it to fix this, and also use int for "test_family" to comply
with the API standard.

udp: only do GSO if # of segs > 1

2019-10-07T17:01:51+00:00

[ Upstream commit 4094871db1d65810acab3d57f6089aa39ef7f648 ]

Prior to this change an application sending <= 1MSS worth of data and
enabling UDP GSO would fail if the system had SW GSO enabled, but the
same send would succeed if HW GSO offload is enabled. In addition to this
inconsistency the error in the SW GSO case does not get back to the
application if sending out of a real device so the user is unaware of this
failure.

With this change we only perform GSO if the # of segments is > 1 even
if the application has enabled segmentation. I've also updated the
relevant udpgso selftests.

ipv6: do not free rt if FIB_LOOKUP_NOREF is set on suppress rule

2019-10-05T13:11:13+00:00

[ Upstream commit ca7a03c4175366a92cee0ccc4fec0038c3266e26 ]

Commit 7d9e5f422150 removed references from certain dsts, but accounting
for this never translated down into the fib6 suppression code. This bug
was triggered by WireGuard users who use wg-quick(8), which uses the
"suppress-prefix" directive to ip-rule(8) for routing all of their
internet traffic without routing loops. The test case added here
causes the reference underflow by causing packets to evaluate a suppress
rule.
