selftests: net: Add tests for team driver decoupled tx and rx control

2026-04-13T13:09:49Z

Use ping and tcpdump to verify that independent rx and tx enablement of team driver member interfaces works as intended.

selftests: net: Add test for enablement of ports with teamd

2026-04-13T13:09:49Z

There are no tests that verify enablement and disablement of team driver ports with teamd. This should work even with changes to the enablement option, so it is important to test. This test sets up an active-backup network configuration across two network namespaces, and tries to send traffic while changing which link is the active one. Also increase the team test timeout to 300 seconds, because gracefully killing teamd can take 30 seconds for each instance.

selftests: net: Add tests for failover of team-aggregated ports

2026-04-13T13:09:49Z

There are currently no kernel tests that verify the effect of setting the enabled team driver option. In a followup patch, there will be changes to this option, so it will be important to make sure it still behaves as it does now. The test verifies that tcp continues to work across two different team devices in separate network namespaces, even when member links are manually disabled.

selftests: team: add non-Ethernet header_ops reproducer

2026-03-24T10:26:32Z

Add a team selftest that sets up: g0 (gre) -> b0 (bond) -> t0 (team) and triggers IPv6 traffic on t0. This reproduces the non-Ethernet header_ops confusion scenario and protects against regressions in stacked team/bond/gre configurations. Using this script, the panic reported by syzkaller can be reproduced [1]. After the fix: # ./non_ether_header_ops.sh PASS: non-Ethernet header_ops stacking did not crash [1] https://syzkaller.appspot.com/bug?extid=3d8bc31c45e11450f24c Cc: Jiayuan Chen Signed-off-by: Jiayuan Chen Link: https://patch.msgid.link/20260320072139.134249-3-jiayuan.chen@linux.dev Signed-off-by: Paolo Abeni

selftests: team: Add a reference count leak test

Add a test for the issue that was fixed in "team: avoid NETDEV_CHANGEMTU event when unregistering slave". The test hangs due to a reference count leak without the fix: # make -C tools/testing/selftests TARGETS="drivers/net/team" TEST_PROGS=refleak.sh TEST_GEN_PROGS="" run_tests [...] TAP version 13 1..1 # timeout set to 45 # selftests: drivers/net/team: refleak.sh [ 50.681299][ T496] unregister_netdevice: waiting for dummy1 to become free.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06Z

We get a significant number of conflicts between net and net-next because of selftests Makefile changes. People tend to append new test cases at the end of the Makefile when there's no clear sort order. Sort all networking selftests Makefiles, use the following format: VAR_NAME := \ entry1 \ entry2 \ entry3 \ # end of VAR_NAME Some Makefiles are already pretty close to this.

selftests: net: Add tests to verify team driver option set and get.

2025-09-11T09:07:55Z

There are currently no kernel tests that verify setting and getting options of the team driver. In the future, options may be added that implicitly change other options, which will make it useful to have tests like these that show nothing breaks. There will be a follow up patch to this that adds new "rx_enabled" and "tx_enabled" options, which will implicitly affect the "enabled" option value and vice versa. The tests use teamnl to first set options to specific values and then gets them to compare to the set values.

selftests: net: validate team flags propagation

2025-05-21T01:12:58Z

Cover three recent cases: 1. missing ops locking for the lowers during netdev_sync_lower_features 2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked with a comment on why/when it's needed) 3. rcu lock during team_change_rx_flags Verified that each one triggers when the respective fix is reverted. Not sure about the placement, but since it all relies on teaming, added to the teaming directory. One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way to trigger netdev_sync_lower_features without it.

selftests: team: Add missing config options

2024-02-01T16:36:20Z

Similar to commit dd2d40acdbb2 ("selftests: bonding: Add more missing config options"), add more networking-specific config options which are needed for team device tests. For testing, I used the minimal config generated by virtme-ng and I added the options in the config file. Afterwards, the team device test passed.
