selftests: netdevsim: Test route offload failure notifications

2021-02-09T00:47:03Z

Add cases to verify that when debugfs variable "fail_route_offload" is set, notification with "rt_offload_failed" flag is received. Extend the existing cases to verify that when sysctl "fib_notify_on_flag_change" is set to 2, the kernel emits notifications only for failed route installation. $ ./fib_notifications.sh TEST: IPv4 route addition [ OK ] TEST: IPv4 route deletion [ OK ] TEST: IPv4 route replacement [ OK ] TEST: IPv4 route offload failed [ OK ] TEST: IPv6 route addition [ OK ] TEST: IPv6 route deletion [ OK ] TEST: IPv6 route replacement [ OK ] TEST: IPv6 route offload failed [ OK ] Signed-off-by: Amit Cohen Signed-off-by: Ido Schimmel Signed-off-by: David S.

net: selftests: Add lanes setting test

2021-02-04T02:37:29Z

Test that setting lanes parameter is working. Set max speed and max lanes in the list of advertised link modes, and then try to set max speed with the lanes below max lanes if exists in the list. And then, test that setting number of lanes larger than max lanes fails. Do the above for both autoneg on and off. $ ./ethtool_lanes.sh TEST: 4 lanes is autonegotiated [ OK ] TEST: Lanes number larger than max width is not set [ OK ] TEST: Autoneg off, 4 lanes detected during force mode [ OK ] TEST: Lanes number larger than max width is not set [ OK ] Signed-off-by: Danielle Ratson Signed-off-by: Jakub Kicinski

selftests: netdevsim: Add fib_notifications test

2021-02-03T01:45:59Z

Add test to check fib notifications behavior. The test checks route addition, route deletion and route replacement for both IPv4 and IPv6. When fib_notify_on_flag_change=0, expect single notification for route addition/deletion/replacement. When fib_notify_on_flag_change=1, expect: - two notification for route addition/replacement, first without RTM_F_TRAP and second with RTM_F_TRAP. - single notification for route deletion. $ ./fib_notifications.sh TEST: IPv4 route addition [ OK ] TEST: IPv4 route deletion [ OK ] TEST: IPv4 route replacement [ OK ] TEST: IPv6 route addition [ OK ] TEST: IPv6 route deletion [ OK ] TEST: IPv6 route replacement [ OK ] Signed-off-by: Amit Cohen Signed-off-by: Ido Schimmel Reviewed-by: David Ahern Signed-off-by: Jakub Kicinski

selftests: Extend fib tests to run with and without flags notifications

2021-02-03T01:45:59Z

Run the test cases with both `fib_notify_on_flag_change` sysctls set to '1', and then with both sysctls set to '0' to verify there are no regressions in the test when notifications are added. Signed-off-by: Amit Cohen Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

selftests: mlxsw: Add a scale test for physical ports

2021-01-23T04:42:13Z

Query the maximum number of supported physical ports using devlink-resource and test that this number can be reached by splitting each of the splittable ports to its width. Test that an error is returned in case the maximum number is exceeded. Signed-off-by: Danielle Ratson Signed-off-by: Ido Schimmel Signed-off-by: Jakub Kicinski

selftests: mlxsw: Set headroom size of correct port

2021-01-04T21:36:32Z

The test was setting the headroom size of the wrong port. This was not visible because of a firmware bug that canceled this bug. Set the headroom size of the correct port, so that the test will pass with both old and new firmware versions.
