2018-06-04selftests: forwarding: mirror_vlan: Change test descriptionPetr Machata
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.

2018-06-04selftests: forwarding: mirror_vlan: Uninstall trapPetr Machata
Instead of installing a trap before tests run and uninstalling it after they run, mirror_vlan.sh installs it twice due to a typo. Fix the typo. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-06-01selftests: forwarding: mirror_gre_bridge_1d_vlan: Add STP testPetr Machata
To test offloading of mirror-to-gretap in mlxsw for cases that a VLAN-unaware bridge is in underlay packet path, test that the STP status of bridge egress port is reflected. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-06-01selftests: forwarding: mirror_gre_vlan_bridge_1q: Add more testsPetr Machata
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.

2018-06-01selftests: forwarding: mirror_gre_vlan_bridge_1q: Rename two testsPetr Machata
Rename test_gretap_forbidden() and test_ip6gretap_forbidden() to a more specific test_gretap_forbidden_cpu() and test_ip6gretap_forbidden_cpu(). This will make it clearer which is which when further down a patch is introduced that forbids a VLAN on regular bridge port. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S.

The "ip6gretap" in the test name refers to the tunnel device type that the test is supposed to be testing. However test_ip6gretap_forbidden() tests, due to a typo, a gretap tunnel. Fix the typo. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-06-01selftests: forwarding: mirror_lib: skip_hw the VLAN capturePetr Machata
When the VLAN capture is installed on a front panel device and not a soft device, the packets are counted twice: once in fast path, and once after they are trapped to the kernel. Resolve the problem by passing skip_hw flag to vlan_capture_install(). Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-05-24selftests: forwarding: lib: Extract trap_{, un}install()Petr Machata
A mirror-to-vlan test that's coming next needs to install the trap unconditionally. Therefore extract from slow_path_trap_{,un}install() a more generic functions trap_install() and trap_uninstall(), and covert the former two to conditional wrappers around these.

2018-05-24selftests: forwarding: Add $h3's clsact to mirror_topo_lib.shPetr Machata

2018-05-24selftests: forwarding: mirror_gre_lib: Extract generic functionsPetr Machata
For non-GRE mirroring tests, a functions along the lines of do_test_span_gre_dir_ips() and test_span_gre_dir_ips() are necessary, but such that they don't assume tunnels are involved. Extract the code from mirror_gre_lib.sh to mirror_lib.sh and convert to just use a given device without assuming it's named "h3-$tundev". Convert the two above-mentioned functions to wrappers that pass along the correct device name. Add test_span_dir() and fail_test_span_dir() to round up the API for use by following patches.

2018-05-03selftests: forwarding: Increase maximum deviation in multipath testIdo Schimmel
We sometimes observe failures in the test due to too large discrepancy between the measured and expected ratios. For example: TEST: ECMP [FAIL] Too large discrepancy between expected and measured ratios INFO: Expected ratio 1.00 Measured ratio 1.11 Fix this by allowing an up to 15% deviation between both ratios. Another possibility is to increase the number of generated flows, but this will prolong the execution time of the test, which is already quite high.
