selftests: team: add non-Ethernet header_ops reproducer

2026-03-24T10:26:32+00:00

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

2026-02-26T03:17:05+00:00

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. Usage count = 3 [ 71.185325][ T496] unregister_netdevice: waiting for dummy1 to become free.

selftests: net: unify the Makefile formats

2025-10-06T20:14:06+00:00

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.

2025-09-11T09:07:55+00:00

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

2025-05-21T01:12:58+00:00

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

2024-02-01T16:36:20+00:00

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.

selftests: forwarding: Remove duplicated lib.sh content

2024-01-31T10:55:11+00:00

commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to contain code shared by tests under net/ and net/forwarding/. However, this caused issues with selftests from directories other than net/forwarding/, in particular those under drivers/net/. Those issues were avoided in a simple way by duplicating some content in commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to remove the duplicated content, restore the inclusion of net/lib.sh from net/forwarding/lib.sh but with the following changes: * net/lib.sh is imported through the net_forwarding_dir path The original expression "source ../lib.sh" would look for lib.sh in the directory above the script file's one, which did not work for tests under drivers/net/. * net/lib.sh is added to TEST_INCLUDES Since net/forwarding/lib.sh now sources net/lib.sh, both of those files must be exported along with tests which source net/forwarding/lib.sh.
