selftests/Makefile: include $(INSTALL_DEP_TARGETS) in clean target to clean net/lib dependency

2025-11-13T20:34:25+00:00

[ Upstream commit d3f7457da7b9527a06dbcbfaf666aa51ac2eeb53 ] The selftests 'make clean' does not clean the net/lib because it only processes $(TARGETS) and ignores $(INSTALL_DEP_TARGETS). This leaves compiled objects in net/lib after cleaning, requiring manual cleanup. Include $(INSTALL_DEP_TARGETS) in clean target to ensure net/lib dependency is properly cleaned.

selftests: net: build net/lib dependency in all target

2025-06-19T13:32:18+00:00

[ Upstream commit d3f2a9587ebe68f5067f9ff624f9a83dfb911f60 ] We have the logic to include net/lib automatically for net related selftests. However, currently, this logic is only in install target which means only `make install` will have net/lib included. This commit adds the logic to all target so that all `make`, `make run_tests` and `make install` will have net/lib included in net related selftests.

selftest/x86/bugs: Add selftests for ITS

2025-05-18T06:24:59+00:00

commit 7a9b709e7cc5ce1ffb84ce07bf6d157e1de758df upstream. Below are the tests added for Indirect Target Selection (ITS): - its_sysfs.py - Check if sysfs reflects the correct mitigation status for the mitigation selected via the kernel cmdline. - its_permutations.py - tests mitigation selection with cmdline permutations with other bugs like spectre_v2 and retbleed. - its_indirect_alignment.py - verifies that for addresses in .retpoline_sites section that belong to lower half of cacheline are patched to ITS-safe thunk. Typical output looks like below: Site 49: function symbol: __x64_sys_restart_syscall+0x1f <0xffffffffbb1509af> # vmlinux: 0xffffffff813509af: jmp 0xffffffff81f5a8e0 # kcore: 0xffffffffbb1509af: jmpq *%rax # ITS thunk NOT expected for site 49 # PASSED: Found *%rax # Site 50: function symbol: __resched_curr+0xb0 <0xffffffffbb181910> # vmlinux: 0xffffffff81381910: jmp 0xffffffff81f5a8e0 # kcore: 0xffffffffbb181910: jmp 0xffffffffc02000fc # ITS thunk expected for site 50 # PASSED: Found 0xffffffffc02000fc -> jmpq *%rax - its_ret_alignment.py - verifies that for addresses in .return_sites section that belong to lower half of cacheline are patched to its_return_thunk. Typical output looks like below: Site 97: function symbol: collect_event+0x48 <0xffffffffbb007f18> # vmlinux: 0xffffffff81207f18: jmp 0xffffffff81f5b500 # kcore: 0xffffffffbb007f18: jmp 0xffffffffbbd5b560 # PASSED: Found jmp 0xffffffffbbd5b560 # Site 98: function symbol: collect_event+0xa4 <0xffffffffbb007f74> # vmlinux: 0xffffffff81207f74: jmp 0xffffffff81f5b500 # kcore: 0xffffffffbb007f74: retq # PASSED: Found retq Some of these tests have dependency on tools like virtme-ng[1] and drgn[2].

selftests: sched_ext: Add sched_ext as proper selftest target

2024-10-09T16:42:51+00:00

The sched_ext selftests is missing proper cross-compilation support, a proper 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 install or: make ARCH=arm64 LLVM=1 TARGETS=sched_ext SKIP_TARGETS="" \ O=/output/foo -C tools/testing/selftests install The expectation is that the sched_ext is included, cross-built, the correct toolchain is picked up, and placed into /output/foo. In contrast to the BPF selftests, the sched_ext suite does not use bpftool at test run-time, so it is sufficient to build bpftool for the build host only. Add ARCH, CROSS_COMPILE, OUTPUT, and TARGETS support to the sched_ext selftest. Also, remove some variables that were unused by the Makefile.

selftests/net: integrate packetdrill with ksft

2024-09-10T00:38:02+00:00

Lay the groundwork to import into kselftests the over 150 packetdrill TCP/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 based conntrack tests"). This patch takes a slightly different approach. It relies on ksft_runner.sh to run every *.pkt file in the directory. Any future imports of packetdrill tests should require no additional coding. Just add the *.pkt files. Initially import only two features/directories from github. One with a single script, and one with two. This was the only reason to pick tcp/inq and tcp/md5. The path replaces the directory hierarchy in github with a flat space of files: $(subst /,_,$(wildcard tcp/**/*.pkt)). This is the most straightforward option to integrate with kselftests. The Linked thread reviewed two ways to maintain the hierarchy: TEST_PROGS_RECURSE and PRESERVE_TEST_DIRS. But both introduce significant changes to kselftest 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.pkt Link: 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.com Signed-off-by: Jakub Kicinski
