selftests: net: use ip commands instead of teamd in team rx_mode test

2026-04-21T10:50:25+00:00

Replace teamd daemon usage with ip link commands for team device setup. teamd -d daemonizes and returns to the shell before port addition completes, creating a race: the test may create the macvlan (and check for its address on a slave) before teamd has finished adding ports. This makes the test inherently dependent on scheduling timing. Using ip commands makes port addition synchronous, removing the race and making the test deterministic.

selftests/net: Split netdevsim tests from HW tests in nk_qlease

2026-04-14T15:17:01+00:00

As pointed out in 3d2c3d2eea9a ("selftests: net: py: explicitly forbid multiple ksft_run() calls"), ksft_run() cannot be called multiple times. Move the netdevsim-based queue lease tests to selftests/net/ so that each file has exactly one ksft_run() call. The HW tests (io_uring ZC RX, queue attrs, XDP with MP, destroy) remain in selftests/drivers/net/hw/.

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

2026-04-13T13:09:49+00:00

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

2026-04-13T13:09:49+00:00

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: drv-net: ntuple: Add dst-ip, src-port, dst-port fields

2026-04-10T22:32:11+00:00

Extend the ntuple flow steering test to cover dst-ip, src-port, and dst-port fields. The test supports arbitrary combinations of the fields, for now we test src_ip/dst_ip, and src_ip/dst_ip/src_port/dst_port. The tests currently match full fields, but we can consider adding support for masked fields in the future.

selftests: drv-net: Add ntuple (NFC) flow steering test

2026-04-10T22:32:11+00:00

Add a test for ethtool NFC (ntuple) flow steering rules. The test creates an ntuple rule matching on various flow fields and verifies that traffic is steered to the correct queue. The test forces all traffic to queue 0 via the indirection table, then installs an ntuple rule to steer select traffic to a specific queue. The test then verifies the expected number of packets is received on the queue. This test has variants for TCP/UDP over IPv4/IPv6, with rules matching the source IP. Additional match fields will be added in the next commit.

selftests: Add MACsec VLAN propagation traffic test

2026-04-10T02:38:42+00:00

Add VLAN filter propagation tests through offloaded MACsec devices via actual traffic. The tests create MACsec tunnels with matching SAs on both endpoints, stack VLANs on top, and verify connectivity with ping. Covered: - Offloaded MACsec with VLAN (filters propagate to HW) - Software MACsec with VLAN (no HW filter propagation) - Offload on/off toggle and verifying traffic still works On netdevsim this makes use of the VLAN filter debugfs file to actually validate that filters are applied/removed correctly. On real hardware the traffic should validate actual VLAN filter propagation.
