2018-08-07selftests: forwarding: gre_multipath: Update next-hop statistics match criteriaNir Dotan1-4/+4
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.

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 <[email protected]> Reviewed-by: Ido Schimmel <[email protected]> Signed-off-by: David S.

However the interface is configured as a member of 192.0.2.160/28 and there's no route directing traffic from the former network through that interface.

2018-07-10selftests: forwarding: mirror_lib: Tighten up VLAN capturePetr Machata1-1/+1
The function do_test_span_vlan_dir_ips() is used for testing whether mirrored packets are VLAN-encapsulated. But since it only considers VLAN encapsulation, it may end up matching unmirrored ARP traffic as well. One consequence is a rare failure of mirror_gre_vlan_bridge_1q's test_gretap_untagged_egress. Decreasing ping cadence in mirror_test() makes the problem easily reproducible. Therefore tighten up the match criterion to only count those 802.1q packets where the next header is IP.

2018-06-30selftests: forwarding: lib: Parameterize NUM_NETIFS in two functionsPetr Machata1-2/+6
setup_wait() and tc_offload_check() both assume that all NUM_NETIFS interfaces are relevant for a given test. However, the scale test script acts as an umbrella for a number of sub-tests, some of which may not require all the interfaces. Thus it's suboptimal for tc_offload_check() to query all the interfaces. In case of setup_wait() it's incorrect, because the sub-test in question of course doesn't configure any interfaces beyond what it needs, and setup_wait() then ends up waiting indefinitely for the extraneous interfaces to come up. For that reason, give setup_wait() and tc_offload_check() an optional parameter with a number of interfaces to probe. Fall back to global NUM_NETIFS if the parameter is not given.

When running mirror_gre_bridge_1d_vlan tests on veth, several issues cause spurious failures: - vlan_ethtype should be ip, not ipv6 even in mirror-to-ip6gretap case, because the overlay packet is still IPv4. - Similarly ip_proto matches the innermost IP protocol, so can't be used to filter out GRE packet.

There are several cases where traffic that would normally be forwarded in silicon needs to be observed in slow path. That's achieved by trapping such traffic, and the functions trap_install() and trap_uninstall() realize that.

Add test for cases where bridge itself acts as a router interface, with front panel port attached to the bridge in question. In the first test (router_bridge.sh), VLAN memberships are not configured in any way, and everything uses default PVID of 1. Thus traffic in $h1 and $h2 is untagged. This test ensures that the previous patches didn't break a currently working scenario. In the second test (router_bridge_vlan.sh), a VLAN 555 pvid untagged is added to the bridge CPU port, with that VLAN leaving the bridge tagged through its sole member port. The traffic is therefore expected to come out tagged at $h1. This tests the fix introduced in the previous patches.
