selftests: Clean forgotten resources as part of cleanup()

2021-07-19T08:00:57Z

[ Upstream commit e67dfb8d15deb33c425d0b0ee22f2e5eef54c162 ] Several tests do not set some ports down as part of their cleanup(), resulting in IPv6 link-local addresses and associated routes not being deleted. These leaks were found using a BPF tool that monitors ASIC resources. Solve this by setting the ports down at the end of the tests.

selftests: mlxsw: Fix mausezahn invocation in ERSPAN scale test

2021-05-19T08:56:20Z

[ Upstream commit 1233898ab758cbcf5f6fea10b8dd16a0b2c24fab ] The mirror_gre_scale test creates as many ERSPAN sessions as the underlying chip supports, and tests that they all work. In order to determine that it issues a stream of ICMP packets and checks if they are mirrored as expected. However, the mausezahn invocation missed the -6 flag to identify the use of IPv6 protocol, and was sending ICMP messages over IPv6, as opposed to ICMP6. It also didn't pass an explicit source IP address, which apparently worked at some point in the past, but does not anymore. To fix these issues, extend the function mirror_test() in mirror_lib by detecting the IPv6 protocol addresses, and using a different ICMP scheme. Fix __mirror_gre_test() in the selftest itself to pass a source IP address. Signed-off-by: Petr Machata Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

selftests: net: mirror_gre_vlan_bridge_1q: Make an FDB entry static

2021-05-14T08:53:03Z

[ Upstream commit c8d0260cdd96fdccdef0509c4160e28a1012a5d7 ] The FDB roaming test installs a destination MAC address on the wrong interface of an FDB database and tests whether the mirroring fails, because packets are sent to the wrong port. The test by mistake installs the FDB entry as local. This worked previously, because drivers were notified of local FDB entries in the same way as of static entries. However that has been fixed in the commit 6ab4c3117aec ("net: bridge: don't notify switchdev for local FDB addresses"), and local entries are not notified anymore. As a result, the HW is not reconfigured for the FDB roam, and mirroring keeps working, failing the test. To fix the issue, mark the FDB entry as static.

selftests: forwarding: vxlan_bridge_1d: Add more ECN decap test cases

Test that all possible combinations of inner and outer ECN bits result in the correct inner ECN marking according to RFC 6040 4.2. Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: vxlan_bridge_1d: Fix vxlan ecn decapsulate value

2021-03-19T20:54:28Z

The ECN bit defines ECT(1) = 1, ECT(0) = 2. So inner 0x02 + outer 0x01 should be inner ECT(0) + outer ECT(1). Based on the description of __INET_ECN_decapsulate, the final decapsulate value should be ECT(1). So fix the test expect value to 0x01. Before the fix: TEST: VXLAN: ECN decap: 01/02->0x02 [FAIL] Expected to capture 10 packets, got 0. After the fix: TEST: VXLAN: ECN decap: 01/02->0x01 [ OK ] Fixes: a0b61f3d8ebf ("selftests: forwarding: vxlan_bridge_1d: Add an ECN decap test") Signed-off-by: Hangbin Liu Signed-off-by: David S.

selftests: forwarding: Fix race condition in mirror installation

2021-02-26T23:47:52Z

When mirroring to a gretap in hardware the device expects to be programmed with the egress port and all the encapsulating headers. This requires the driver to resolve the path the packet will take in the software data path and program the device accordingly. If the path cannot be resolved (in this case because of an unresolved neighbor), then mirror installation fails until the path is resolved. This results in a race that causes the test to sometimes fail. Fix this by setting the neighbor's state to permanent, so that it is always valid.

selftests: tc: Add generic mpls matching support for tc-flower

2021-02-13T01:13:52Z

Add tests in tc_flower.sh for generic matching on MPLS Label Stack Entries. The label, tc, bos and ttl fields are tested for the first and second labels. For each field, the minimal and maximal values are tested (the former at depth 1 and the later at depth 2). There are also tests for matching the presence of a label stack entry at a given depth. In order to reduce the amount of code, all "lse" subcommands are tested in match_mpls_lse_test(). Action "continue" is used, so that test packets are evaluated by all filters. Then, we can verify if each filter matched the expected number of packets. Some versions of tc-flower produced invalid json output when dumping MPLS filters with depth > 1. Skip the test if tc isn't recent enough. Signed-off-by: Guillaume Nault Signed-off-by: David S. Miller
