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

2025-09-27T00:48:40+00:00

Most forwarding tests invoke forwarding_enable() to enable the router and forwarding_restore() to restore the original configuration. Add a helper, adf_forwarding_enable(), which is like forwarding_enable(), but takes care of scheduling the cleanup automatically. Convert the tests that currently use defer to schedule the cleanup.

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

Most forwarding tests invoke simple_if_init() to set up a VRF-based "host" and simple_if_fini() to tear it down again. Add a helper, adf_simple_if_init(), which is like simple_if_fini(), but takes care of scheduling the cleanup automatically. Convert the tests that currently use defer to schedule the cleanup.

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.

selftests: bonding: add test for LACP actor port priority

2025-09-09T08:56:02+00:00

Add comprehensive selftest to verify: - Per-port actor priority setting via ad_actor_port_prio - Aggregator selection behavior with port_priority ad_select policy Also move cmd_jq helper from forwarding/lib.sh to net/lib.sh for broader reusability across network selftests. Here is the result output # ./bond_lacp_prio.sh TEST: bond 802.3ad (ad_actor_port_prio setting) [ OK ] TEST: bond 802.3ad (ad_actor_port_prio select) [ OK ] TEST: bond 802.3ad (ad_actor_port_prio switch) [ OK ] Signed-off-by: Hangbin Liu Link: https://patch.msgid.link/20250902064501.360822-4-liuhangbin@gmail.com Signed-off-by: Paolo Abeni

selftests: tc: Add generic erspan_opts matching support for tc-flower

2025-07-21T23:12:09+00:00

Add test cases to tc_flower.sh to validate generic matching on ERSPAN options. Both ERSPAN Type II and Type III are covered. Also add check_tc_erspan_support() to verify whether tc supports erspan_opts.

selftests: forwarding: lib: Split setup_wait()

2025-06-27T00:53:07+00:00

setup_wait() takes an optional argument and then is called from the top level of the test script. That confuses shellcheck, which thinks that maybe the intention is to pass $1 of the script to the function, which is never the case. To avoid having to annotate every single new test with a SC disable, split the function in two: one that takes a mandatory argument, and one that takes no argument at all. Convert the two existing users of that optional argument, both in Spectrum resource selftest, to use the new form. Clean up vxlan_bridge_1q_mc_ul.sh to not pass a now-unused argument.

selftests: forwarding: adf_mcd_start(): Allow configuring custom interfaces

2025-06-18T01:18:46+00:00

Tests may wish to add other interfaces to listen on. Notably locally generated traffic uses dummy interfaces. The multicast daemon needs to know about these so that it allows forming rules that involve these interfaces, and so that net.ipv4.conf.X.mc_forwarding is set for the interfaces. To that end, allow passing in a list of interfaces to configure in addition to all the physical ones.

selftests: forwarding: lib: Move smcrouted helpers here

2025-06-18T01:18:46+00:00

router_multicast.sh has several helpers for work with smcrouted. Extract them to lib.sh so that other selftests can use them as well. Convert the helpers to defer in the process, because that simplifies the interface quite a bit. Therefore have router_multicast.sh invoke defer_scopes_cleanup() in its cleanup() function.

selftests: forwarding: lib: Move require_command to net, generalize

2025-02-18T12:06:43+00:00

This helper could be useful to more than just forwarding tests. Move it upstairs and port over to log_test_skip(). Split the function into two parts: the bit that actually checks and reports skip, which is in a new function check_command(). And a bit that exits the test script if the check fails. This allows users consistent checking behavior while giving an option to bail out from a single test without bailing out of the whole script.
