selftests: forwarding: gre_multipath: Update next-hop statistics match criteria

2018-08-07T23:02:30+00:00

gre_multipath test was using egress vlan_id matching on flows, for the purpose of collecting next-hops statistics, later to be compared against configured weights. As matching on vlan_id on egress direction is not supported on all HW devices, change the match criteria to use destination IP. Signed-off-by: Nir Dotan Acked-by: Petr Machata Signed-off-by: David S.

selftests: forwarding: Move DSCP capture to lib.sh

2018-08-01T16:52:30+00:00

dscp_capture_install() and dscp_capture_uninstall() are going to be useful for a test added by a following patch, move them therefore to lib.sh together with related helpers. While doing so, change the rule preference from mere DSCP value to DSCP+100 in order to support adding captures of packets with DSCP of 0.

selftests: forwarding: Move lldpad waiting to lib.sh

2018-08-01T16:52:30+00:00

The function lldpad_wait() will be useful for a test added by a following patch. Likewise would the "sleep 5" with its extensive comment. Therefore move lldpad_wait() to lib.sh in order to allow reuse. Rename it to lldpad_app_wait_set() to recognize that what this is intended to wait on are the pending APP sets. For the sleeping, add a function lldpad_app_wait_del(). That will serve to hold the related explanatory comment (which edit for clarity), and as a token in the caller to identify the sites where this sort of waiting takes place. That will serve when/if a better way to handle this business is found. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: Test mirror-to-gretap w/ UL team LACP

2018-07-30T16:47:21+00:00

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.

selftests: forwarding: Test mirror-to-gretap w/ UL team

2018-07-30T16:47:21+00:00

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. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: Introduce $ARPING

2018-07-30T16:47:21+00:00

Instead of relying on "arping" being installed everywhere under that name, introduce a variable $ARPING like the other tools do. Convert an existing test, mirror_gre_vlan_bridge_1q.sh to require_command $ARPING and then invoke arping through the variable. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: lib: Support team devices

Add team_create() and team_destroy() to manage team netdevices. Signed-off-by: Petr Machata Signed-off-by: David S. Miller

selftests: forwarding: lib: Add require_command()

2018-07-30T16:47:21+00:00

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.

selftests: add a selftest for directed broadcast forwarding

2018-07-29T19:37:06+00:00

As Ido's suggestion, this patch is to add a selftest for directed broadcast forwarding with vrf. It does the assertion by checking the src IP of the echo-reply packet in ping_test_from. Signed-off-by: Xin Long Signed-off-by: David S. Miller
