* | selftests: forwarding: mirror_gre_nh: Unset rp_filter on host VRFPetr Machata2018-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | The mirrored packets arrive at $h3 encapsulated in GRE/IPv4, with IP address from 192.0.2.128/28 network. 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. Correspondingly, the RP filter on the VRF rejects it. Therefore turn off the VRF's RP filter. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* | selftests: forwarding: mirror_lib: Tighten up VLAN capturePetr Machata2018-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | selftests: forwarding: Allow importing dependent librariesPetr Machata2018-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The next patch introduces a new mlxsw-specific test that uses mirror_gre_lib.sh and mirror_gre_topo_lib.sh. However when sourcing their own deps, these libraries assume that the test that's running is in the same directory. That's not the case for driver-specific tests. So change the libraries to source their deps through $relative_path. That variable is set up by lib.sh, which should be imported by the test in question in any case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Drop the corresponding condition. - Because the above fixes the filters to match in slow path as well, they need to be made skip_hw so as not to double-count packets.

* | selftests: forwarding: lib: Avoid trapping soft devicesPetr Machata2018-06-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. However, such treatment is obviously wrong if the device in question is actually a soft device not backed by an ASIC. Therefore try to trap if possible, but fall back to inserting a continue if not.

| | | | | | | | | | | | | | | | | | | | The test description is displayed with the PASS/FAIL resolution after the test is ran. There however already is one other test described exactly like this, which makes it unclear which of the tests passed or failed. Make the description unique.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add regression tests for PF_PACKET transmission using packet_snd. The TPACKET ring interface has tests for transmission and reception. This is an initial stab at the same for the send call based interface. Packets are sent over loopback, then read twice. The entire packet is read from another packet socket and compared. The packet is also verified to arrive at a UDP socket for protocol conformance. The test sends a packet over loopback, testing the following options (not the full cross-product): - SOCK_DGRAM - SOCK_RAW - vlan tag - qdisc bypass - bind() and sendto() - virtio_net_hdr - csum offload (NOT actual csum feature, ignored on loopback) - gso Besides these basic functionality tests, the test runs from a set of bounds checks, positive and negative. Running over loopback, which has dev->min_header_len, it cannot generate variable length hhlen. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

Verify that irrespective of gso_size, udpgso restricts the number of segments it will generate per call (UDP_MAX_SEGMENTS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Offloading of mirror-to-gretap in mlxsw is tricky especially in cases when the gretap underlay involves bridges. Add more tests that exercise the bridge handling code: - forbidden_egress tests that check vlan removal on bridge port in the underlay packet path - untagged_egress tests that similarly check "egress untagged" - fdb_roaming tests that check whether learning FDB on a different port is reflected - stp tests for handling port STP status of bridge egress port Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.
