selftests: bonding: cause oops in bond_rr_gen_slave_id

2022-09-22T13:39:40Z

This bonding selftest used to cause a kernel oops on aarch64 and should be architectures agnostic. Signed-off-by: Jonathan Toppins Acked-by: Jay Vosburgh Signed-off-by: Jakub Kicinski

net: Add tests for bonding and team address list management

2022-09-16T13:34:01Z

Test that the bonding and team drivers clean up an underlying device's address lists (dev->uc, dev->mc) when the aggregated device is deleted. Test addition and removal of the LACPDU multicast address on underlying devices by the bonding driver. v2: * add lag_lib.sh to TEST_FILES v3: * extend bond_listen_lacpdu_multicast test to init_state up and down cases * remove some superfluous shell syntax and 'set dev ... up' commands Signed-off-by: Benjamin Poirier Signed-off-by: David S.

selftests: include bonding tests into the kselftest infra

2022-08-23T01:30:16Z

This creates a test collection in drivers/net/bonding for bonding specific kernel selftests. The first test is a reproducer that provisions a bond and given the specific order in how the ip-link(8) commands are issued the bond never transmits an LACPDU frame on any of its slaves.

selftests: netdevsim: Add test cases for route deletion failure

2022-07-29T11:21:02Z

Add IPv4 and IPv6 test cases that ensure that we are not leaking a reference on the nexthop device when we are unable to delete its associated route. Without the fix in a previous patch ("netdevsim: fib: Fix reference count leak on route deletion failure") both test cases get stuck, waiting for the reference to be released from the dummy device [1][2].

selftests: net: dsa: Add a Makefile which installs the selftests

2022-07-29T05:04:31Z

Add a Makefile which takes care of installing the selftests in tools/testing/selftests/drivers/net/dsa. This can be used to install all DSA specific selftests and forwarding.config using the same approach as for the selftests in tools/testing/selftests/net/forwarding.

selftests: mlxsw: Add a RIF counter scale test

2022-06-17T09:31:33Z

This tests creates as many RIFs as possible, ideally more than there can be RIF counters (though that is currently only possible on Spectrum-1). It then tries to enable L3 HW stats on each of the RIFs. It also contains the traffic test, which tries to run traffic through a log2 of those counters and checks that the traffic is shown in the counter values. Like with tc_flower traffic test, take a log2 subset of rules. The logic behind picking log2 rules is that then every bit of the instantiated item's number is exercised. This should catch issues whether they happen at the high end, low end, or somewhere in between. Signed-off-by: Petr Machata Reviewed-by: Amit Cohen Signed-off-by: Ido Schimmel Signed-off-by: David S.
