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.

selftests: forwarding: Add a test for NH group stats

2024-03-11T21:14:10+00:00

Add to lib.sh support for fetching NH stats, and a new library, router_mpath_nh_lib.sh, with the common code for testing NH stats. Use the latter from router_mpath_nh.sh and router_mpath_nh_res.sh. The test works by sending traffic through a NH group, and checking that the reported values correspond to what the link that ultimately receives the traffic reports having seen.

selftests: forwarding: List helper scripts in TEST_FILES Makefile variable

2024-02-01T16:36:36+00:00

Some scripts are not tests themselves; they contain utility functions used by other tests. According to Documentation/dev-tools/kselftest.rst, such files should be listed in TEST_FILES. Currently they are incorrectly listed in TEST_PROGS_EXTENDED so rename the variable.

selftests: forwarding: Remove duplicated lib.sh content

2024-01-31T10:55:11+00:00

commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to contain code shared by tests under net/ and net/forwarding/. However, this caused issues with selftests from directories other than net/forwarding/, in particular those under drivers/net/. Those issues were avoided in a simple way by duplicating some content in commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to remove the duplicated content, restore the inclusion of net/lib.sh from net/forwarding/lib.sh but with the following changes: * net/lib.sh is imported through the net_forwarding_dir path The original expression "source ../lib.sh" would look for lib.sh in the directory above the script file's one, which did not work for tests under drivers/net/. * net/lib.sh is added to TEST_INCLUDES Since net/forwarding/lib.sh now sources net/lib.sh, both of those files must be exported along with tests which source net/forwarding/lib.sh.
