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: forwarding: Add a test for FDB activity notification control

2025-08-14T00:09:54+00:00

Test various aspects of FDB activity notification control: * Transitioning of an FDB entry from inactive to active state. * Transitioning of an FDB entry from active to inactive state. * Avoiding the resetting of an FDB entry's last activity time (i.e., "updated" time) using the "norefresh" keyword.

selftests: forwarding: Add a selftest for the new reserved_bits UAPI

2024-12-09T22:47:06+00:00

Run VXLAN packets through a gateway. Flip individual bits of the packet and/or reserved bits of the gateway, and check that the gateway treats the packets as expected.

selftests: net: include lib/sh/*.sh with lib.sh

2024-11-06T00:46:39+00:00

Recently, the net/lib.sh file has been modified to include defer.sh from net/lib/sh/ directory. The Makefile from net/lib has been modified accordingly, but not the ones from the sub-targets using net/lib.sh. Because of that, the new file is not installed as expected when installing the Forwarding, MPTCP, and Netfilter targets, e.g. # make -C tools/testing/selftests TARGETS=net/mptcp install \ INSTALL_PATH=/tmp/kself # cd /tmp/kself/ # ./run_kselftest.sh -c net/mptcp TAP version 13 1..7 # timeout set to 1800 # selftests: net/mptcp: mptcp_connect.sh # ./../lib.sh: line 5: /tmp/kself/net/lib/sh/defer.sh: No such file or directory # (...) This can be fixed simply by adding all the .sh files from net/lib/sh directory to the TEST_INCLUDES variable in the different Makefile's.

selftests: forwarding: Add test for minimum and maximum MTU

2024-06-15T02:30:34+00:00

Add cases to check minimum and maximum MTU which are exposed via "ip -d link show". Test configuration and traffic. Use VLAN devices as usually VLAN header (4 bytes) is not included in the MTU, and drivers should configure hardware correctly to send maximum MTU payload size in VLAN tagged packets. $ ./min_max_mtu.sh TEST: ping [ OK ] TEST: ping6 [ OK ] TEST: Test maximum MTU configuration [ OK ] TEST: Test traffic, packet size is maximum MTU [ OK ] TEST: Test minimum MTU configuration [ OK ] TEST: Test traffic, packet size is minimum MTU [ OK ] Signed-off-by: Amit Cohen Reviewed-by: Petr Machata Signed-off-by: Petr Machata Link: https://lore.kernel.org/r/89de8be8989db7a97f3b39e3c9da695673e78d2e.1718275854.git.petrm@nvidia.com Signed-off-by: Jakub Kicinski

selftests: forwarding: router_mpath_hash: Add a new selftest

2024-06-12T23:42:12+00:00

Add a selftest that exercises the sysctl added in the previous patches. Test that set/get works as expected; that across seeds we eventually hit all NHs (test_mpath_seed_*); and that a given seed keeps hitting the same NHs even across seed changes (test_mpath_seed_stability_*).

selftests: forwarding: Add a test for testing lib.sh functionality

2024-03-29T01:03:43+00:00

Rerunning various scenarios to make sure lib.sh changes do not impact the observable behavior is no fun. Add a selftest at least for the bare basics -- the mechanics of setting RET, retmsg, and EXIT_STATUS. Since the selftest itself uses lib.sh, it would be possible to break lib.sh in such a way that invalidates result of the selftest. Since the metatest only uses the bare basics (just pass/fail), hopefully such fundamental breakages would be noticed.

selftests: forwarding: Move several selftests

2024-03-29T01:03:42+00:00

The tests in net/forwarding are generally expected to be HW-independent. There are however several tests that, while not depending on any HW in particular, nevertheless depend on being used on HW interfaces. Placing these selftests to net/forwarding is confusing, because the selftest will just report it can't be run on veth pairs. At the same time, placing them to a particular driver's selftests subdirectory would be wrong. Instead, add a new directory, drivers/net/hw, where these generic but HW independent selftests should be placed. Move over several such tests including one helper library. Since typically these tests will not be expected to run, omit the directory drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a Makefile in the new directory itself, so that a user can make -C into that directory and act on those tests explicitly.
