selftests: bonding: do not set port down before adding to bond

2023-08-30T12:52:32Z

[ Upstream commit be809424659c2844a2d7ab653aacca4898538023 ] Before adding a port to bond, it need to be set down first. In the lacpdu test the author set the port down specifically. But commit a4abfa627c38 ("net: rtnetlink: Enslave device before bringing it up") changed the operation order, the kernel will set the port down _after_ adding to bond. So all the ports will be down at last and the test failed. In fact, the veth interfaces are already inactive when added. This means there's no need to set them down again before adding to the bond. Let's just remove the link down operation.

selftests: bonding: re-format bond option tests

2023-04-07T07:47:20Z

To improve the testing process for bond options, A new bond topology lib is added to our testing setup. The current option_prio.sh file will be renamed to bond_options.sh so that all bonding options can be tested here. Specifically, for priority testing, we will run all tests using modes 1, 5, and 6. These changes will help us streamline the testing process and ensure that our bond options are rigorously evaluated.

selftests: bonding: add tests for ether type changes

2023-03-17T07:56:41Z

Add new network selftests for the bonding device which exercise the ether type changing call paths. They also test for the recent syzbot bug[1] which causes a warning and results in wrong device flags (IFF_SLAVE missing). The test adds three bond devices and a nlmon device, enslaves one of the bond devices to the other and then uses the nlmon device for successful and unsuccesful enslaves both of which change the bond ether type. Thus we can test for both MASTER and SLAVE flags at the same time. If the flags are properly restored we get: TEST: Change ether type of an enslaved bond device with unsuccessful enslave [ OK ] TEST: Change ether type of an enslaved bond device with successful enslave [ OK ] [1] https://syzkaller.appspot.com/bug?id=391c7b1f6522182899efba27d891f1743e8eb3ef Signed-off-by: Nikolay Aleksandrov Reviewed-by: Michal Kubiak Acked-by: Jonathan Toppins Acked-by: Jay Vosburgh Signed-off-by: David S.

Verify when a bond is configured with {up,down}delay and the link state of slave members flaps if there are no remaining members up the bond should immediately select a member to bring up.

selftests: net: Fix cross-tree inclusion of scripts

2022-10-21T04:09:22Z

When exporting and running a subset of selftests via kselftest, files from parts of the source tree which were not exported are not available. A few tests are trying to source such files. Address the problem by using symlinks. The problem can be reproduced by running: make -C tools/testing/selftests gen_tar TARGETS="drivers/net/bonding" [... extract archive ...] ./run_kselftest.sh or: make kselftest KBUILD_OUTPUT=/tmp/kselftests TARGETS="drivers/net/bonding" Fixes: bbb774d921e2 ("net: Add tests for bonding and team address list management") Fixes: eccd0a80dc7f ("selftests: net: dsa: add a stress test for unlocked FDB operations") Link: https://lore.kernel.org/netdev/40f04ded-0c86-8669-24b1-9a313ca21076@redhat.com/ Reported-by: Jonathan Toppins Signed-off-by: Benjamin Poirier Reviewed-by: Jonathan Toppins Signed-off-by: Jakub Kicinski

selftests/bonding: re-add lladdr target test

2022-09-23T13:26:05Z

It looks like this test has been accidentally dropped when resolving conflicts in this Makefile. Most probably because there were 3 different patches modifying this file in parallel: commit 152e8ec77640 ("selftests/bonding: add a test for bonding lladdr target") commit bbb774d921e2 ("net: Add tests for bonding and team address list management") commit 2ffd57327ff1 ("selftests: bonding: cause oops in bond_rr_gen_slave_id") The first one was applied in 'net-next' while the two other ones were recently applied in the 'net' tree. But that's alright, easy to fix by re-adding the missing one!
