selftests: forwarding: gre_multipath: Fix flower filters

2019-08-29T06:28:30+00:00

[ Upstream commit 1be79d89b7ae96e004911bd228ce8c2b5cc6415f ]

The TC filters used in the test do not work with veth devices because the
outer Ethertype is 802.1Q and not IPv4. The test passes with mlxsw
netdevs since the hardware always looks at "The first Ethertype that
does not point to either: VLAN, CNTAG or configurable Ethertype".

Fix this by matching on the VLAN ID instead, but on the ingress side.
The reason why this is not performed at egress is explained in the
commit cited below.

selftests: forwarding: gre_multipath: Enable IPv4 forwarding

2019-08-29T06:28:29+00:00

[ Upstream commit efa7b79f675da0efafe3f32ba0d6efe916cf4867 ]

The test did not enable IPv4 forwarding during its setup phase, which
causes the test to fail on machines where IPv4 forwarding is disabled.

selftests: fib_rule_tests: Fix icmp proto with ipv6

[ Upstream commit 15d55bae4e3c43cd9f87fd93c73a263e172d34e1 ]

A recent commit returns an error if icmp is used as the ip-proto for
IPv6 fib rules. Update fib_rule_tests to send ipv6-icmp instead of icmp.

The IPv4 testing address are all in 192.51.100.0 subnet. It doesn't make
sense to set a 198.51.100.1 local address. Should be a typo.

selftests/net: correct the return value for run_netsocktests

2019-05-16T17:41:24+00:00

[ Upstream commit 30c04d796b693e22405c38e9b78e9a364e4c77e6 ]

The run_netsocktests will be marked as passed regardless the actual test
result from the ./socket:

    ========================================
    --------------------
    running socket test
    --------------------
    [FAIL]
    ok 1..6 selftests: net: run_netsocktests [PASS]

This is because the test script itself has been successfully executed.
Fix this by exit 1 when the test failed.

selftests: fib_tests: Fix 'Command line is not complete' errors

2019-05-16T17:41:21+00:00

[ Upstream commit a5f622984a623df9a84cf43f6b098d8dd76fbe05 ]

A couple of tests are verifying a route has been removed. The helper
expects the prefix as the first part of the expected output. When
checking that a route has been deleted the prefix is empty leading
to an invalid ip command:

  $ ip ro ls match
  Command line is not complete. Try option "help"

Fix by moving the comparison of expected output and output to a new
function that is used by both check_route and check_route6. Use the
new helper for the 2 checks on route removal.

Also, remove the reset of 'set -x' in route_setup which overrides the
user managed setting.

selftests: fib_tests: sleep after changing carrier. again.

2019-03-23T19:09:52+00:00

[ Upstream commit af548a27b158d548d41e56255e6eaca1658cc3be ]

Just like commit e2ba732a1681 ("selftests: fib_tests: sleep after
changing carrier"), wait one second to allow linkwatch to propagate the
carrier change to the stack.

There are two sets of carrier tests. The first slept after the carrier
was set to off, and when the second set ran, it was likely that the
linkwatch would be able to run again without much delay, reducing the
likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a
loop, you will quickly notice the failures.

Sleeping on the second set of tests make the failures go away.

selftests: net: use LDLIBS instead of LDFLAGS

It's GNU Make and linker specific.

The default Makefile rule looks like:

$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)

When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.

More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html

LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.

LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.

tools/perf: libraries must come after objects

Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libnuma.
