selftests: bonding: fix incorrect mac address

2025-03-11T12:19:27+00:00

The correct mac address for NS target 2001:db8::254 is 33:33:ff:00:02:54,
not 33:33:00:00:02:54. The same with client maddress.

selftests: bonding: set active slave to primary eth1 specifically

2024-02-19T09:11:35+00:00

In bond priority testing, we set the primary interface to eth1 and add
eth0,1,2 to bond in serial. This is OK in normal times. But when in
debug kernel, the bridge port that eth0,1,2 connected would start
slowly (enter blocking, forwarding state), which caused the primary
interface down for a while after enslaving and active slave changed.
Here is a test log from Jakub's debug test[1].

Fix it by setting active slave to primary slave specifically before
testing.

2024-02-16T08:02:39+00:00

One of Jakub's tests[1] shows that there may be period all ports
are down and no active slave. This makes the new_active_slave null
and the test fails. Add a check to make sure the new active is not null.

selftests: bonding: use slowwait instead of hard code sleep

2024-02-08T02:26:20+00:00

Use slowwait instead of hard code sleep for bonding tests.

In function setup_prepare(), the client_create() will be called after
server_create(). So I think there is no need to sleep in server_create()
and remove it.

For lab_lib.sh, remove bonding module may affect other running bonding tests.
And some test env may buildin bond which can't be removed. The bonding
link should be removed by lag_reset_network() or netns delete.

selftests: bonding: reduce garp_test/arp_validate test time

2024-02-08T02:26:20+00:00

The purpose of grat_arp is testing commit 9949e2efb54e ("bonding: fix
send_peer_notif overflow"). As the send_peer_notif was defined to u8,
to overflow it, we need to

send_peer_notif = num_peer_notif * peer_notif_delay = num_grat_arp * peer_notify_delay / miimon > 255
  (kernel)           (kernel parameter)                   (user parameter)

e.g. 30 (num_grat_arp) * 1000 (peer_notify_delay) / 100 (miimon) > 255.

Which need 30s to complete sending garp messages. To save the testing time,
the only way is reduce the miimon number. Something like
30 (num_grat_arp) * 100 (peer_notify_delay) / 10 (miimon) > 255.

To save more time, the 50 num_grat_arp testing could be removed.

The arp_validate_test also need to check the mii_status, which sleep
too long. Use slowwait to save some time.

For other connection checkings, make sure active slave changed first.

2024-02-08T02:26:20+00:00

Use tc filter to check if LACP was sent, which is accurate and save
more time.

No need to remove bonding module as some test env may buildin bonding.
And the bond link has been deleted.
