2018-05-25selftests: forwarding: Test mirror-to-vlanPetr Machata1-0/+169
Test for "tc action mirred egress mirror" that mirrors to a vlan device. - test_vlan() tests that the packets get mirrored - test_tagged_vlan() tests that the mirrored packets have correct inner VLAN tag.

2018-05-25selftests: forwarding: lib: Extract trap_{, un}install()Petr Machata1-9/+18
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.

2018-05-25selftests: forwarding: Add $h3's clsact to mirror_topo_lib.shPetr Machata3-4/+2
Having a clsact qdisc on $h3 is useful in several tests, and will be useful in more tests to come. Move the registration from all the tests that need it into the topology file itself. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-05-25selftests: forwarding: mirror_gre_lib: Extract generic functionsPetr Machata2-31/+64
For non-GRE mirroring tests, a functions along the lines of do_test_span_gre_dir_ips() and test_span_gre_dir_ips() are necessary, but such that they don't assume tunnels are involved. Extract the code from mirror_gre_lib.sh to mirror_lib.sh and convert to just use a given device without assuming it's named "h3-$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.

Similar to commit a511858c7536 ("selftests: fib_tests: Allow user to run a specific test"), allow user to run only a subset of the tests using the TESTS environment variable. This is useful when not all the tests can pass on a given system.

2018-05-03selftests: forwarding: Increase maximum deviation in multipath testIdo Schimmel1-1/+1
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.

To simplify implementation of mirror-to-gretap tests, extend lib.sh with several new functions that might potentially be useful more broadly (although right now the mirroring tests will be the only client). Also add mirror_lib.sh with code useful for mirroring tests, mirror_gre_lib.sh with code specifically useful for mirror-to-gretap tests, and mirror_gre_topo.sh that primes a given test with a good baseline topology that the test can then tweak to its liking.
