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

selftests: tc: Add basic mpls_* matching support for tc-flower

2021-02-13T01:13:52Z

Add tests in tc_flower.sh for mpls_label, mpls_tc, mpls_bos and mpls_ttl. For each keyword, test the minimal and maximal values. Selectively skip these new mpls tests for tc versions that don't support them. Signed-off-by: Guillaume Nault Signed-off-by: David S. Miller

flow_dissector: fix TTL and TOS dissection on IPv4 fragments

2021-02-13T01:03:51Z

the following command: # tc filter add dev $h2 ingress protocol ip pref 1 handle 101 flower \ $tcflags dst_ip 192.0.2.2 ip_ttl 63 action drop doesn't drop all IPv4 packets that match the configured TTL / destination address. In particular, if "fragment offset" or "more fragments" have non zero value in the IPv4 header, setting of FLOW_DISSECTOR_KEY_IP is simply ignored. Fix this dissecting IPv4 TTL and TOS before fragment info; while at it, add a selftest for tc flower's match on 'ip_ttl' that verifies the correct behavior.

selftests: tc: add ingress device matching support

2019-06-19T14:09:22Z

Extend tc_flower to test plain ingress device matching and also tc_shblock to test ingress device matching on shared block. Add new tc_flower_router.sh where ingress device matching on egress (after routing) is done. Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: Allow running specific tests

2018-05-03T16:54:31Z

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. Example: # export TESTS="ping_ipv4 ping_ipv6" # ./bridge_vlan_aware.sh TEST: ping [PASS] TEST: ping6 [PASS] Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Reviewed-by: Jiri Pirko Signed-off-by: David S.
