2021-10-12selftests: mlxsw: RED: Add selftests for the mark qeventPetr Machata2-5/+122
Add do_mark_test(), which is to do_ecn_test() like do_drop_test() is to do_red_test(): meant to test that actions on the RED mark qevent block are offloaded, and executed on ECN-marked packets. The test splits install_qdisc() into its constituents, install_root_qdisc() and install_qdisc_tcX(). This is in order to test that when mirroring is enabled on one TC, the other TC does not mirror.

2021-06-08selftests: router_scale: Do not count failed routesAmit Cohen1-1/+1
To check how many routes are installed in hardware, the test runs "ip route" and greps for "offload", which includes routes with state "offload_failed". Till now, this wrong check was not found because after one failure in route insertion, the driver moved to "abort" mode, which means that user cannot try to add more routes. The previous patch removed the abort mechanism and now failed routes are counted as offloaded. Fix this by not considering routes with "offload_failed" flag as offloaded.

2021-04-23selftests: mlxsw: Fix mausezahn invocation in ERSPAN scale testPetr Machata1-1/+2
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 <petrm@nvidia.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-23selftests: mlxsw: Increase the tolerance of backlog buildupPetr Machata1-2/+2
The intention behind this test is to make sure that qdisc limit is correctly projected to the HW. However, first, due to rounding in the qdisc, and then in the driver, the number cannot actually be accurate. And second, the approach to testing this is to oversubscribe the port with traffic generated on the same switch. The actual backlog size therefore fluctuates. In practice, this test proved to be noisier than the rest, and spuriously fails every now and then. Increase the tolerance to 10 % to avoid these issues.

2021-04-23selftests: mlxsw: Return correct error code in resource scale testsDanielle Ratson2-2/+6
Currently, the resource scale test checks a few cases, when the error code resets between the cases. So for example, if one case fails and the consecutive case passes, the error code eventually will fit the last test and will be 0. Save a new return code that will hold the 'or' return codes of all the cases, so the final return code will consider all the cases.

The number of nexthop buckets in a resilient nexthop group never changes, so when the gateway address of a nexthop cannot be resolved, the nexthop buckets are programmed to trap packets to the CPU in order to trigger resolution. For example: # ip nexthop add id 1 via 198.51.100.1 dev swp3 # ip nexthop add id 10 group 1 type resilient buckets 32 # ip nexthop bucket get id 10 index 0 id 10 index 0 idle_time 1.44 nhid 1 trap Where 198.51.100.1 is a made-up IP.

It is currently the only ad-hoc tool available (in contrast to a daemon that manages an interface on an ongoing basis). However, it is very verbose and parsing out error messages is not really possible. Add a wrapper that makes it easier to use the tool.

2020-09-30selftests: forwarding: devlink_lib: Split devlink_..._set() into save & setPetr Machata4-0/+21
Changing pool type from static to dynamic causes reinterpretation of threshold values. They therefore need to be saved before pool type is changed, then the pool type can be changed, and then the new values need to be set up. For that reason, set cannot subsume save, because it would be saving the wrong thing, with possibly a nonsensical value, and restore would then fail to restore the nonsensical value. Thus extract a _save() from each of the relevant _set()'s. This way it is possible to save everything up front, then to tweak it, and then restore in the required order.

2020-08-24selftests: mlxsw: Reduce runtime of tc-police scale testIdo Schimmel1-2/+10
Currently, the test takes about 626 seconds to complete because of an inefficient use of the device's TCAM. Reduce the runtime to 202 seconds by inserting all the flower filters with the same preference and mask, but with a different key. In particular, this reduces the deletion of the qdisc (which triggers the deletion of all the filters) from 66 seconds to 0.2 seconds. This prevents various netlink requests from user space applications (e.g., systemd-networkd) from timing-out because RTNL is not held for too long anymore.

2020-08-24selftests: mlxsw: Increase burst size for burst testIdo Schimmel1-25/+2
The current combination of rate and burst size does not adhere to Spectrum-{2,3} limitation which states that the minimum burst size should be 40% of the rate. Increase the burst size in order to honor above mentioned limitation and avoid intermittent failures of this test case on Spectrum-{2,3}. Remove the first sub-test case as the variation in number of received packets is simply too large to reliably test it. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
