bbb5e2e31a5476d376ce1d0004c6168585fe1a7f - Merge branch 'selftests-bpf-tolerate-partial-builds-across-kernel-configs'

Fri, 05 Jun 2026 23:20:58 +0200

Merge branch 'selftests-bpf-tolerate-partial-builds-across-kernel-configs'Ricardo B. Marliere says:====================selftests/bpf: Tolerate partial builds across kernel configsCurrently the BPF selftests can only be built by using the minimum kernelconfiguration defined in tools/testing/selftests/bpf/config*. This poses aproblem in distribution kernels that may have some of the flags disabled orset as module. For example, we have been running the tests regularly inopenSUSE Tumbleweed [1] [2] but to work around this fact we created aspecial package [3] that build the tests against an auxiliary vmlinux withthe BPF Kconfig. We keep a list of known issues that may happen due to,amongst other things, configuration mismatches [4] [5].The maintenance of this package is far from ideal, especially forenterprise kernels. The goal of this series is to enable the common usecaseof running the following in any system:```shmake -C tools/testing/selftests install \ SKIP_TARGETS= \ TARGETS=bpf \ BPF_STRICT_BUILD=0 \ O=/lib/modules/$(uname -r)/build```As an example, the following script targeting a minimal config can be usedfor testing:```shmake defconfigscripts/config --file .config \ --enable DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT \ --enable DEBUG_INFO_BTF \ --enable BPF_SYSCALL \ --enable BPF_JITmake olddefconfigmake -j$(nproc)make -j$(nproc) -C tools/testing/selftests install \ SKIP_TARGETS= \ TARGETS=bpf \ BPF_STRICT_BUILD=0```This produces a test_progs binary with 592 subtests, against the total of727. Many of them will still fail or be skipped at runtime due to lack ofsymbols, but at least there will be a clear way of building the tests.[1]: https://openqa.opensuse.org/tests/5811715[2]: https://openqa.opensuse.org/tests/5811730[3]: https://src.opensuse.org/rmarliere/kselftests[4]: https://github.com/openSUSE/kernel-qe/blob/main/kselftests_known_issues.yaml[5]: https://openqa.opensuse.org/tests/5811730/logfile?filename=run_kselftests-config_mismatches.txt---Changes in v12:- Rebase from 11 to 8 commits: split the test_kmods KDIR patch into a pure KDIR fix (no PERMISSIVE) and a separate tolerance patch;

they are already in $^ as normal prerequisites (patch 8)- Reorder: move skip-unbuilt-tests patch before partial-linking patch for bisectability- Link to v5: https://patch.msgid.link/20260415-selftests-bpf_misconfig-v5-0-03d0a52a898a@suse.comChanges in v5:- Add BPF_STRICT_BUILD toggle as patch 1 so every subsequent patch gates tolerance behind PERMISSIVE from the start, making the series bisectable with strict-by-default at every point- Fix O= commit message;

9779193e871b144e34ec4a3e50109b3778a51a69 - selftests/bpf: Fix test_kmods KDIR to honor O= and distro kernels

Tue, 02 Jun 2026 15:02:51 +0200

selftests/bpf: Fix test_kmods KDIR to honor O= and distro kernelstest_kmods/Makefile always pointed KDIR at the kernel source tree root,ignoring O= and KBUILD_OUTPUT. On distro kernels where the source tree hasnot been built, the Makefile had no fallback and would failunconditionally.When O= or KBUILD_OUTPUT is set and points at a prepared kernel builddirectory (one containing Module.symvers), pass it through so kbuild canlocate the correct build infrastructure (scripts, Kconfig, etc.). Notethat the module artifacts themselves still land in the M= directory,which is test_kmods/; O= only controls where kbuild finds its buildinfrastructure. Fall back to /lib/modules/$(uname -r)/build when neitheran explicit valid build directory nor an in-tree Module.symvers ispresent.A selftests-only O= value (one that does not contain Module.symvers, e.g.a private output directory) is intentionally not treated as a kernelbuild directory. Without this guard, a user invoking"make -C tools/testing/selftests/bpf O=/tmp/out" would have test_kmodstry to use /tmp/out as the kernel build dir and fail.The parent bpf/Makefile resolves O= and KBUILD_OUTPUT to absolute pathsbefore invoking the test_kmods sub-make. Without this, $(abspath ...)inside test_kmods/Makefile would resolve relative paths against thesub-make's CWD (test_kmods/) rather than the user's invocation directory.When O= is passed to kbuild, also pass KBUILD_OUTPUT=$(KMOD_O_VALID)explicitly. The parent invocation lifts KBUILD_OUTPUT into MAKEFLAGS asa command-line variable, which would otherwise suppress kbuild's own"KBUILD_OUTPUT := $(O)" assignment and cause it to use the inheritedKBUILD_OUTPUT instead of the validated O=.Guard both all and clean against a missing KDIR so the step is silentlyskipped rather than fatal. Make the parent Makefile's cp conditional so itdoes not abort when modules were not built.Signed-off-by: Ricardo B.
