This patchset adds a test for "tc action mirred mirror" where the
mirrored-to device is a gretap, and underlay path contains a team
device.
In patch #1 require_command() is added, which should henceforth be used
to declare dependence on a certain tool.
In patch #2, two new functions, team_create() and team_destroy(), are
added to lib.sh.
The newly-added test uses arping, which isn't necessarily available.
Therefore patch #3 introduces $ARPING, and a preexisting test is fixed
to require_command $ARPING.
In patches #4 and #5, two new tests are added. In both cases, a team
device is on egress path of a mirrored packet in a mirror-to-gretap
scenario. In the first one, the team device is in loadbalance mode, in
the second one it's in lacp mode. (The difference in modes necessitates
a different testing strategy, hence two test cases instead of just
parameterizing one.)

The logic for testing whether a certain command is available is used
several times in the current code base. The tests in follow-up patches
add more requirements like that.
Therefore extract the logic into a named function, require_command(),
that can be used directly from lib.sh as well as from any test that
wishes to declare dependence on some command.

Instead of relying on "arping" being installed everywhere under that

Convert an existing test, mirror_gre_vlan_bridge_1q.sh to

Test for "tc action mirred egress mirror" that mirrors to gretap when
the underlay route points at a VLAN-aware bridge (802.1q), and the
traffic egresses the bridge through a team device. Test upping and
downing individual team device slaves and verify the traffic flows as
expected.

Test for "tc action mirred egress mirror" that mirrors to gretap when
the underlay route points at a VLAN-aware bridge (802.1q), and the
traffic egresses the bridge through a team device. Test upping and
downing individual team device slaves and verify the traffic flows as
expected.

* [PATCH net-next 5/5] selftests: forwarding: Test mirror-to-gretap w/ UL team LACP

This tests mirror-to-gretap when an underlay packet path includes a team
device which is not in loadbalance mode, but in LACP mode. The test
manipulates LAG membership to achieve changes in txability, thus making
sure that a driver that offloads mirror-to-gretap doesn't just consider
upness of a device.

^ permalink raw reply related [flat|nested] 21+ messages in thread* [PATCH net-next 5/5] selftests: forwarding: Test mirror-to-gretap w/ UL team LACP
@ 2018-07-30 14:40 ` Petr Machata
0 siblings, 0 replies; 21+ messages in thread
From: Petr Machata @ 2018-07-30 14:40 UTC (permalink / raw)
This tests mirror-to-gretap when an underlay packet path includes a team
device which is not in loadbalance mode, but in LACP mode. The test
manipulates LAG membership to achieve changes in txability, thus making
sure that a driver that offloads mirror-to-gretap doesn't just consider
upness of a device.
