selftests: sched_ext: Add sched_ext as proper selftest targetThe sched_ext selftests is missing proper cross-compilation support, aproper target entry, and out-of-tree build support.When building the kselftest suite, e.g.: make ARCH=riscv CROSS_COMPILE=riscv64-linux-gnu- \ TARGETS=sched_ext SKIP_TARGETS="" O=/output/foo \ -C tools/testing/selftests installor: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests installThe expectation is that the sched_ext is included, cross-built, thecorrect toolchain is picked up, and placed into /output/foo.In contrast to the BPF selftests, the sched_ext suite does not usebpftool at test run-time, so it is sufficient to build bpftool for thebuild host only.Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_extselftest.

8a405552 - selftests/net: integrate packetdrill with ksft

Thu, 05 Sep 2024 23:15:52 +0000

selftests/net: integrate packetdrill with ksftLay the groundwork to import into kselftests the over 150 packetdrillTCP/IP conformance tests on github.com/google/packetdrill.Florian recently added support for packetdrill tests in nf_conntrack,in commit a8a388c2aae49 ("selftests: netfilter: add packetdrill basedconntrack tests").This patch takes a slightly different approach. It relies onksft_runner.sh to run every *.pkt file in the directory.Any future imports of packetdrill tests should require no additionalcoding. Just add the *.pkt files.Initially import only two features/directories from github. One with asingle script, and one with two. This was the only reason to picktcp/inq and tcp/md5.The path replaces the directory hierarchy in github with a flat spaceof files: $(subst /,_,$(wildcard tcp/**/*.pkt)). This is the moststraightforward option to integrate with kselftests. The Linked threadreviewed two ways to maintain the hierarchy: TEST_PROGS_RECURSE andPRESERVE_TEST_DIRS. But both introduce significant changes tokselftest infra and with that risk to existing tests.Implementation notes:- restore alphabetical order when adding the new directory to tools/testing/selftests/Makefile- imported *.pkt files and support verbatim from the github project, except for - update `source ./defaults.sh` path (to adjust for flat dir) - add SPDX headers - remove one author statement - Acknowledgment: drop an e (checkpatch)Tested: make -C tools/testing/selftests \ TARGETS=net/packetdrill \ run_tests make -C tools/testing/selftests \ TARGETS=net/packetdrill \ install INSTALL_PATH=$KSFT_INSTALL_PATH # in virtme-ng ./run_kselftest.sh -c net/packetdrill ./run_kselftest.sh -t net/packetdrill:tcp_inq_client.pktLink: https://lore.kernel.org/netdev/20240827193417.2792223-1-willemdebruijn.kernel@gmail.com/Signed-off-by: Willem de Bruijn Link: https://patch.msgid.link/20240905231653.2427327-3-willemdebruijn.kernel@gmail.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/Makefile
