ipv6: When forwarding count rx stats on the orig netdev

2021-10-27T07:56:48+00:00

[ Upstream commit 0857d6f8c759d95f89d0436f86cdfd189ef99f20 ] Commit bdb7cc643fc9 ("ipv6: Count interface receive statistics on the ingress netdev") does not work when ip6_forward() executes on the skbs with vrf-enslaved netdev. Use IP6CB(skb)->iif to get to the right one. Add a selftest script to verify.

selftests: ocelot: add some example VCAP IS1, IS2 and ES0 tc offloads

2020-10-02T22:40:30+00:00

Provide an example script which can be used as a skeleton for offloading TCAM rules in the Ocelot switches. Not all actions are demoed, mostly because of difficulty to automate this from a single board. For example, policing. We can set up an iperf3 UDP server and client and measure throughput at destination. But at least with DSA setups, network namespacing the individual ports is not possible because all switch ports are handled by the same DSA master. And we cannot assume that the target platform (an embedded board) has 2 other non-switch generator ports, we need to work with the generator ports as switch ports (this is the reason why mausezahn is used, and not IP traffic like ping). When somebody has an idea how to test policing, that can be added to this test. Signed-off-by: Vladimir Oltean Signed-off-by: David S. Miller

selftests: forwarding: ETS: Use Qdisc counters

2020-03-05T22:03:32+00:00

Currently the SW-datapath ETS selftests use "ip link" stats to obtain the number of packets that went through a given band. mlxsw then uses ethtool per-priority counters. Instead, change both to use qdiscs. In SW datapath this is the obvious choice, and now that mlxsw offloads FIFO, this should work on the offloaded datapath as well. This has the effect of verifying that the FIFO offload works. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: Convert until_counter_is() to take expression

2020-03-04T01:03:52+00:00

until_counter_is() currently takes as an argument a number and the condition holds when the current counter value is >= that number. Make the function more generic by taking a partial expression instead of just the number. Convert the two existing users. Signed-off-by: Petr Machata Reviewed-by: Amit Cohen Signed-off-by: David S.

selftests: forwarding: lib: Add tc_rule_handle_stats_get()

2020-03-04T01:03:52+00:00

The function tc_rule_stats_get() fetches a given statistic of a TC rule given the rule preference. Another common way to reference a rule is using its handle. Introduce a dual to the aforementioned function that gets a statistic given rule handle. Signed-off-by: Petr Machata Reviewed-by: Amit Cohen Signed-off-by: David S. Miller

selftests: mlxsw: Add a RED selftest

2020-02-27T19:10:14+00:00

This tests that below the queue minimum length, there is no dropping / marking, and above max, everything is dropped / marked. The test is structured as a core file with topology and test code, and three wrappers: one for RED used as a root Qdisc, and two for testing (W)RED under PRIO and ETS.
