selftests: mlxsw: Add a TBF selftest

2020-01-25T09:56:31+00:00

Add a test that runs traffic across a port throttled with TBF. The test checks that the observed throughput is within +-5% from the installed shaper. To allow checking both the software datapath and the offloaded one, make the test suitable for inclusion from driver-specific wrapper. Introduce such wrappers for mlxsw.

selftests: forwarding: lib: Allow reading TC rule byte counters

2020-01-25T09:56:31+00:00

The function tc_rule_stats_get() fetches a packet counter of a given TC rule. Extend it to support byte counters as well by adding an optional argument with selector. Signed-off-by: Petr Machata Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: lib: Add helpers for busywaiting

2020-01-25T09:56:31+00:00

The function busywait() is handy as a safety-latched variant of a while loop. Many selftests deal specifically with counter values, and busywaiting on them is likely to be rather common (it is not quite common now, but busywait() has not been around for very long). To facilitate expressing simply what is tested, introduce two helpers: - until_counter_is(), which can be used as a predicate passed to busywait(), which holds when expression, which is itself passed as an argument to until_counter_is(), reaches a desired value. - busywait_for_counter(), which is useful for waiting until a given counter changes "by" (as opposed to "to") a certain amount.

selftests: Move two functions from mlxsw's qos_lib to lib

2020-01-25T09:56:31+00:00

The function humanize() is used for converting value in bits/s to a human-friendly approximate value in Kbps, Mbps or Gbps. There is nothing hardware-specific in that, so move the function to lib.sh. Similarly for the rate() function, which just does a bit of math to calculate a rate, given two counter values and a time interval.

selftests: forwarding: Add helpers and tests for FIB offload

2020-01-15T02:53:35+00:00

Implement a set of common helpers and tests for FIB offload that can be used by multiple drivers to check their FIB offload implementations. Signed-off-by: Ido Schimmel Acked-by: Jiri Pirko Signed-off-by: David S. Miller

Merge git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net

2020-01-09T20:13:43+00:00

The ungrafting from PRIO bug fixes in net, when merged into net-next, merge cleanly but create a build failure. The resolution used here is from Petr Machata. Signed-off-by: David S. Miller

selftests: forwarding: router: Add test case for destination IP link-local

2020-01-06T21:38:37+00:00

Add test case to check that packets are not dropped when they need to be routed and their destination is link-local, i.e., 169.254.0.0/16. Signed-off-by: Amit Cohen Acked-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: router: Add test case for source IP equals destination IP

2020-01-06T21:38:36+00:00

Add test case to check that packets are not dropped when they need to be routed and their source IP equals to their destination IP. Signed-off-by: Amit Cohen Acked-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller

selftests: forwarding: router: Add test case for multicast destination MAC mismatch

2020-01-06T21:38:36+00:00

Add test case to check that packets are not dropped when they need to be routed and their multicast MAC mismatched to their multicast destination IP. i.e., destination IP is multicast and * for IPV4: DMAC != {01-00-5E-0 (25 bits), DIP[22:0]} * for IPV6: DMAC != {33-33-0 (16 bits), DIP[31:0]} Signed-off-by: Amit Cohen Acked-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.

selftests: forwarding: router: Add test case for source IP in class E

2020-01-06T21:38:36+00:00

Add test case to check that packets are not dropped when they need to be routed and their source IP in class E, (i.e., 240.0.0.0 – 255.255.255.254). Signed-off-by: Amit Cohen Acked-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S. Miller
