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: 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.

selftests: forwarding: extend ethtool_std_stats_get with pause statistics

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

Even though pause frame statistics are not exported through the same ethtool command, there is no point in adding another helper just for them. Extent the ethtool_std_stats_get() function so that we are able to interrogate using the same helper all the standard statistics. And since we are touching the function, convert the initial ethtool call as well to the jq --arg form in order to be easier to read.

selftests: forwarding: lib: Add an autodefer variant of forwarding_enable()

selftests: forwarding: Reorder (ar)ping arguments to obey POSIX getopt

2025-09-22T18:37:20+00:00

Quoted from musl wiki: GNU getopt permutes argv to pull options to the front, ahead of non-option arguments. musl and the POSIX standard getopt stop processing options at the first non-option argument with no permutation. Thus these scripts stop working on musl since non-option arguments for tools using getopt() (in this case, (ar)ping) do not always come last. Fix it by reordering arguments.
