selftest: net: Extend ipmr.c for IP6MR.

2026-06-09T00:06:22+00:00

This commit extends most test cases in ipmr.c for IPV6MR. Note that IP6MR does not provide rtnetlink interface for MFC, so such tests are added to XFAIL_ADD(). Signed-off-by: Kuniyuki Iwashima Link: https://patch.msgid.link/20260604224712.3209821-2-kuniyu@google.com Signed-off-by: Jakub Kicinski

selftests: bridge_vlan_mcast: Test toggling of multicast snooping

2026-05-20T01:15:22+00:00

Test toggling of multicast snooping when per-VLAN multicast snooping is enabled. The test always passes, but without "bridge: mcast: Fix possible use-after-free when removing a bridge port" it results in a splat.

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: forwarding: lib: rewrite processing of command line arguments

2026-04-09T02:26:44+00:00

The piece of code which processes the command line arguments and populates NETIFS based on them is really unobvious. Rewrite it so that the intention is clear and the code is easy to follow.

selftests: net: bridge_vlan_mcast: wait for h1 before querier check

2026-04-08T03:16:16+00:00

The querier-interval test adds h1 (currently a slave of the VRF created by simple_if_init) to a temporary bridge br1 acting as an outside IGMP querier. The kernel VRF driver (drivers/net/vrf.c) calls cycle_netdev() on every slave add and remove, toggling the interface admin-down then up. Phylink takes the PHY down during the admin-down half of that cycle. Since h1 and swp1 are cable-connected, swp1 also loses its link may need several seconds to re-negotiate. Use setup_wait_dev $h1 0 which waits for h1 to return to UP state, so the test can rely on the link being back up at this point.

selftests: net: update some helpers to use run_on

2026-04-02T10:11:03+00:00

Update some helpers so that they are capable to run commands on different targets than the local one. This patch makes the necesasy modification for those helpers / sections of code which are needed for the ethtool_rmon.sh test that will be converted in the next patches. For example, mac_addr_prepare() and mac_addr_restore() used when STABLE_MAC_ADDRS=yes need to ensure stable MAC addresses on interfaces located even in other namespaces. In order to do that, append the 'ip link' commands with a 'run_on $dev' tag. The same run_on is necessary also when verifying if all the interfaces listed in NETIFS are indeed available.

selftests: net: extend lib.sh to parse drivers/net/net.config

2026-04-02T10:11:03+00:00

Extend lib.sh so that it's able to parse driver/net/net.config and environment variables such as NETIF, REMOTE_TYPE, LOCAL_V4 etc described in drivers/net/README.rst. In order to make the transition towards running with a single local interface smoother for the bash networking driver tests, beside sourcing the net.config file also translate the new env variables into the old style based on the NETIFS array. Since the NETIFS array only holds the network interface names, also add a new array - TARGETS - which keeps track of the target on which a specific interfaces resides - local, netns or accesible through an ssh command. For example, a net.config which looks like below: NETIF=eth0 LOCAL_V4=192.168.1.1 REMOTE_V4=192.168.1.2 REMOTE_TYPE=ssh REMOTE_ARGS=root@192.168.1.2 will generate the NETIFS and TARGETS arrays with the following data. NETIFS[p1]="eth0" NETIFS[p2]="eth2" TARGETS[eth0]="local:" TARGETS[eth2]="ssh:root@192.168.1.2" The above will be true if on the remote target, the interface which has the 192.168.1.2 address is named eth2. Since the TARGETS array is indexed by the network interface name, document a new restriction README.rst which states that the remote interface cannot have the same name as the local one. Keep the old way of populating the NETIFS variable based on the command line arguments. This will be invoked in case DRIVER_TEST_CONFORMANT = "no". Also add a couple of helpers which can be used by tests which need to run a specific bash command on a different target than the local system, be it either another netns or a remote system accessible through ssh. The __run_on() function is passed through $1 the target on which the command should be executed while run_on() is passed the name of the interface that is then used to retrieve the target from the TARGETS array. Also add a stub run_on() function in net/lib.sh so that users of the net/lib.sh are going through the stub only since neither NETIFS nor TARGETS are valid in that circumstance.
