f72aa1b2 - selftests: net: include lib/sh/*.sh with lib.sh

selftests: net: include lib/sh/*.sh with lib.shRecently, the net/lib.sh file has been modified to include defer.sh fromnet/lib/sh/ directory. The Makefile from net/lib has been modifiedaccordingly, but not the ones from the sub-targets using net/lib.sh.Because of that, the new file is not installed as expected wheninstalling 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/shdirectory to the TEST_INCLUDES variable in the different Makefile's.Fixes: a6e263f125cd ("selftests: net: lib: Introduce deferred commands")Signed-off-by: Matthieu Baerts (NGI0) Reviewed-by: Petr Machata Link: https://patch.msgid.link/20241104-net-next-selftests-lib-sh-deps-v1-1-7c9f7d939fc2@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/forwarding/Makefile

8ff2d7ab - selftests: forwarding: Add a test for testing lib.sh functionality

Tue, 26 Mar 2024 16:54:41 +0000

selftests: forwarding: Add a test for testing lib.sh functionalityRerunning various scenarios to make sure lib.sh changes do not impact theobservable 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.shin such a way that invalidates result of the selftest. Since the metatestonly uses the bare basics (just pass/fail), hopefully such fundamentalbreakages would be noticed.Signed-off-by: Petr Machata Link: https://lore.kernel.org/r/6d25cedbf2d4b83614944809a34fe023fbe8db38.1711464583.git.petrm@nvidia.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/forwarding/Makefile

40d269c0 - selftests: forwarding: Move several selftests

Tue, 26 Mar 2024 16:54:32 +0000

selftests: forwarding: Move several selftestsThe tests in net/forwarding are generally expected to be HW-independent.There are however several tests that, while not depending on any HW inparticular, nevertheless depend on being used on HW interfaces. Placingthese selftests to net/forwarding is confusing, because the selftest willjust report it can't be run on veth pairs. At the same time, placing themto a particular driver's selftests subdirectory would be wrong.Instead, add a new directory, drivers/net/hw, where these generic but HWindependent selftests should be placed. Move over several such testsincluding one helper library.Since typically these tests will not be expected to run, omit the directorydrivers/net/hw from the TARGETS list in selftests/Makefile. Retain aMakefile in the new directory itself, so that a user can make -C into thatdirectory and act on those tests explicitly.Cc: Roger Quadros Cc: Tobias Waldekranz Cc: Danielle Ratson Cc: Davide Caratti Cc: Johannes Nixdorf Suggested-by: Jakub Kicinski Signed-off-by: Petr Machata Link: https://lore.kernel.org/r/e11dae1f62703059e9fc2240004288ac7cc15756.1711464583.git.petrm@nvidia.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/net/forwarding/Makefile

521ed1ce - selftests: forwarding: Remove duplicated lib.sh content

Fri, 26 Jan 2024 23:21:23 +0000

selftests: forwarding: Remove duplicated lib.sh contentcommit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh tocontain code shared by tests under net/ and net/forwarding/. However, thiscaused issues with selftests from directories other than net/forwarding/,in particular those under drivers/net/. Those issues were avoided in asimple 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 ofnet/lib.sh from net/forwarding/lib.sh but with the following changes:* net/lib.sh is imported through the net_forwarding_dir pathThe original expression "source ../lib.sh" would look for lib.sh in thedirectory above the script file's one, which did not work for tests underdrivers/net/.* net/lib.sh is added to TEST_INCLUDESSince net/forwarding/lib.sh now sources net/lib.sh, both of those filesmust be exported along with tests which source net/forwarding/lib.sh.Suggested-by: Hangbin Liu Reviewed-by: Hangbin Liu Signed-off-by: Petr Machata Signed-off-by: Benjamin Poirier Signed-off-by: David S.
