2026-06-07KVM: selftests: Add a hugetlb memslot alignment test modeJinyu Tang
kvm_page_table_test can already exercise hugetlb-backed guest memory, but it always creates the test memslot with GPA alignment matching the hugetlb backing size. That misses the case where a valid hugetlb memslot is later moved so that the memslot GPA and HVA no longer have the same offset within the backing huge page. Add a -u option that moves the test memslot GPA by one guest page after creating the hugetlb memslot. The memslot is created through the normal helper first, so the backing allocation remains valid and hugetlb aligned. Moving the memslot then creates a deliberate HVA/GPA offset mismatch before the guest mapping is installed. This mode is useful for checking that architecture MMUs do not install a block mapping when the block would map the wrong host pages or cover memory outside the memslot. The option is restricted to hugetlb-backed test memory because it's specifically about hugetlb block mapping eligibility.

2026-06-06selftests/riscv: fix compiler output flag spacing in all MakefilesZong Li
Standardize the compiler output flag format across all RISC-V selftests by adding a space between '-o' and '$@'. Although '-o$@' is perfectly valid for GCC/Clang to parse, changing it to '-o $@' with a space aligns with the GNU official documentation conventions, improves readability by visually separating the flag from the target variable, and ensures consistency with other architectures. Currently, RISC-V selftests use '-o$@' (without space) in 13 instances across 6 Makefiles, while all other architectures consistently use '-o $@' (with space). This inconsistency makes RISC-V an outlier in the kernel's selftest infrastructure.

2026-06-06selftests/bpf: add tests for PTR_TO_FLOW_KEYS offset boundsNuoqi Gui
Add verifier tests covering pointer arithmetic on a PTR_TO_FLOW_KEYS register. This covers the bpf-next regression where an out-of-bounds constant offset introduced as flow_keys += K and then dereferenced at insn->off 0 was accepted, while the equivalent flow_keys + K direct offset was rejected. The tests check that in-bounds constant arithmetic on the keys pointer is still accepted, out-of-bounds constant arithmetic is rejected for both read and write, and a truly varying offset from bpf_get_prandom_u32() remains rejected by the existing PTR_TO_FLOW_KEYS pointer arithmetic rules.

2026-06-05selftests/bpf: Tolerate missing files during installRicardo B. Marlière
With partial builds, some TEST_GEN_FILES entries can be absent at install time. rsync treats missing source arguments as fatal and aborts kselftest installation. Override INSTALL_SINGLE_RULE in selftests/bpf to use --ignore-missing-args, while keeping the existing bpf-specific INSTALL_RULE extension logic. Also add --ignore-missing-args to the TEST_INST_SUBDIRS rsync loop so that subdirectories with no .bpf.o files (e.g. when a test runner flavor was skipped) do not abort installation. Note that the INSTALL_SINGLE_RULE override applies globally to all file categories including static source files (TEST_PROGS, TEST_FILES).

2026-06-05selftests/bpf: Provide weak definitions for cross-test functionsRicardo B. Marlière
Some test files reference functions defined in other translation units that may not be compiled when skeletons are missing. Replace forward declarations of uprobe_multi_func_{1,2,3}() with weak no-op stubs so the linker resolves them regardless of which objects are present. The stub bodies are `asm volatile ("")` rather than empty, matching the shape of the strong definitions in prog_tests/uprobe_multi_test.c. This keeps the weak and strong sides on the same footing for the optimiser (noinline + asm-barrier), which is the form upstream already relies on for these functions. Move stack_mprotect() from test_lsm.c into testing_helpers.c so it is always available. The previous weak-stub approach returned 0, which would cause callers expecting -1/EPERM to fail their assertions deterministically. Having the real implementation in a shared utility avoids this problem entirely. Include <alloca.h> for alloca() so the build does not rely on glibc's implicit declaration via <stdlib.h>.

2026-06-05selftests/bpf: Tolerate benchmark build failuresRicardo B. Marlière
Benchmark objects depend on skeletons that may be missing when some BPF programs fail to build. In that case, benchmark object compilation or final bench linking should not abort the full selftests/bpf build. Keep both steps non-fatal, emit SKIP-BENCH or SKIP-LINK, and remove failed outputs so stale objects or binaries are not reused by later incremental builds. Note that because bench.c statically references every benchmark via extern symbols, partial linking is not possible: if any single benchmark object fails, the entire bench binary is skipped. This is by design -- the error handler catches all compilation failures including genuine ones, but those are caught by full-config CI runs. Signed-off-by: Ricardo B.

2026-06-05selftests/bpf: Allow test_progs to link with a partial object setRicardo B. Marlière
When individual test files are skipped due to compilation failures, their .test.o files are absent. The linker step currently lists all expected .test.o files as explicit prerequisites, so make considers any missing one an error. In permissive mode, declare the test objects that already exist on disk (via parse-time $(wildcard ...)) as normal prerequisites of the binary so that modifications to a test source still trigger a relink, and keep the full TRUNNER_TEST_OBJS list as order-only prerequisites so that initial fresh builds still produce them and missing objects do not abort the link. The recipe filter is split per mode: in permissive mode it combines a recipe-time $(wildcard ...) (which catches objects freshly produced via the order-only path on a fresh build) with $(filter-out $(TRUNNER_TEST_OBJS),$^) (which keeps the non-test inputs from $^ but drops the parse-time wildcard duplicates). This avoids passing the same .test.o twice to the linker while still presenting test objects before libbpf.a so that GNU ld, which scans static archives left-to-right, pulls in archive members referenced exclusively by test objects (e.g. ring_buffer__new from ringbuf.c). In default (strict) mode the recipe remains the simple $(filter %.a %.o,$^) since TRUNNER_TEST_OBJS is part of $^ exactly once. Gate the partial-link behavior on $(if $(filter test_progs%,$1),...) so it only applies to test_progs and its flavors. test_maps and similar runners using strong cross-object references would link-fail with a partial set and intentionally retain strict link semantics. Note: adding a brand-new test_*.c file in permissive mode requires removing the binary (or a clean rebuild) before the new test is linked in, because the parse-time $(wildcard ...) is evaluated when the Makefile is read and will not yet see the new .test.o. This is acceptable since permissive mode targets tolerant CI builds rather than incremental development. Signed-off-by: Ricardo B.

2026-06-05selftests/bpf: Tolerate test file compilation failuresRicardo B. Marlière
Individual test files may fail to compile when headers or kernel features required by that test are absent. Currently this aborts the entire build. Make the per-test compilation non-fatal: remove the output object on failure and print a SKIP-TEST marker to stderr. Guard the BTFIDS post-processing step so it is skipped when the object file is absent. The linker step will later ignore absent objects, allowing the remaining tests to build and run. Group cd and CC in a sub-shell so a cd failure cannot leak into the error-handling branch and operate in the original working directory; use $@ (absolute path) for $(RM) so it cannot match an unrelated file there. Replace the $(call msg,...) in the BTFIDS block with a plain printf (the msg macro expands to @printf, which is a make-recipe construct and is invalid inside a shell if-then-fi body) and gate the printf on $(filter 1,$(V)) so verbose mode (V=1) does not double-print the line that the recipe shell already echoes; non-verbose modes (V unset, V=0, V=2, ...) still print the BTFIDS marker, matching the convention of the shared msg macro. Restrict tolerance to test_progs and its flavors via an inlined $(if $(filter test_progs%,$1),$(if $(PERMISSIVE),...)) check: runners with strong cross-object references (e.g. test_maps) would link-fail with a partial object set, so they keep strict semantics even when BPF_STRICT_BUILD=0. The check is inlined rather than stored in a helper variable so $1 is substituted at $(call) time and the per-runner result is baked into each recipe. Note on bisectability: this change is gated entirely behind PERMISSIVE for test_progs%, so default builds (BPF_STRICT_BUILD!=0) compile and run identically at every commit in the series. Bisecting in PERMISSIVE mode at this commit still requires the next two patches ("selftests/bpf: Skip tests whose objects were not built" and "selftests/bpf: Allow test_progs to link with a partial object set") to avoid the linker rejecting missing objects and the runtime aborting on NULL function pointers.

2026-06-05selftests/bpf: Make skeleton headers order-only prerequisites of .test.dRicardo B. Marlière
The .test.d dependency files are generated by the C preprocessor and list the headers each test file actually #includes. Skeleton headers appear in those generated lists, so the .test.o -> .skel.h dependency is already tracked by the .d file content. Making skeletons order-only prerequisites of .test.d means that a missing or skipped skeleton does not prevent .test.d generation, and regenerating a skeleton does not force .test.d to be recreated. This avoids unnecessary recompilation and, more importantly, avoids build errors when a skeleton was intentionally skipped due to a BPF compilation failure. $$(BPFOBJ) is intentionally kept as a normal prerequisite: a libbpf rebuild legitimately invalidates .test.d, since libbpf header changes can affect the headers .test.o sees. Only the skeleton headers are moved to order-only. Note that adding a new BPF skeleton via a modified existing local header still works correctly: GNU make builds order-only prerequisites that do not exist (the order-only qualifier only suppresses timestamp-driven rebuilds, not existence-driven builds), so a brand-new .skel.h listed in TRUNNER_BPF_SKELS is generated even when .test.d is otherwise up to date. The modified local header invalidates .test.o through the previously included .d content, forcing a recompile that regenerates .test.d with the new .skel.h dependency captured by gcc -MMD.

2026-06-05selftests/bpf: Avoid rebuilds when running emit_testsRicardo B. Marlière
emit_tests is used while installing selftests to generate the kselftest list. Pulling in .d files for this goal can trigger BPF rebuild rules and mix build output into list generation. Skip dependency file inclusion for emit_tests, like clean goals, so list generation stays side-effect free. Also add emit_tests to NON_CHECK_FEAT_TARGETS so that feature detection is skipped; without this, Makefile.feature's $(info) output leaks into stdout and corrupts the test list captured by the top-level selftests Makefile.

2026-06-05selftests/bpf: Tolerate BPF and skeleton generation failuresRicardo B. Marlière
Some BPF programs cannot be built on distro kernels because required BTF types or features are missing. A single failure currently aborts the selftests/bpf build. Make BPF object and skeleton generation best effort in permissive mode: emit SKIP-BPF or SKIP-SKEL to stderr, remove failed outputs so downstream rules can detect absence, and continue with remaining tests. Apply the same tolerance to linked skeletons (TRUNNER_BPF_SKELS_LINKED), which depend on multiple .bpf.o files and abort the build when any dependency is missing. Note that progress messages (GEN-SKEL, LINK-BPF) are also redirected to stderr as a side effect of rewriting the recipes into single-shell pipelines; the $(call msg,...) macro is a make-recipe construct that cannot be used inside an &&-chained shell command sequence.

2026-06-05selftests/bpf: Fix test_kmods KDIR to honor O= and distro kernelsRicardo B. Marlière
test_kmods/Makefile always pointed KDIR at the kernel source tree root, ignoring O= and KBUILD_OUTPUT. On distro kernels where the source tree has not been built, the Makefile had no fallback and would fail unconditionally. When O= or KBUILD_OUTPUT is set and points at a prepared kernel build directory (one containing Module.symvers), pass it through so kbuild can locate the correct build infrastructure (scripts, Kconfig, etc.). Note that the module artifacts themselves still land in the M= directory, which is test_kmods/; O= only controls where kbuild finds its build infrastructure. Fall back to /lib/modules/$(uname -r)/build when neither an explicit valid build directory nor an in-tree Module.symvers is present. A selftests-only O= value (one that does not contain Module.symvers, e.g. a private output directory) is intentionally not treated as a kernel build directory. Without this guard, a user invoking "make -C tools/testing/selftests/bpf O=/tmp/out" would have test_kmods try to use /tmp/out as the kernel build dir and fail. The parent bpf/Makefile resolves O= and KBUILD_OUTPUT to absolute paths before invoking the test_kmods sub-make. Without this, $(abspath ...) inside test_kmods/Makefile would resolve relative paths against the sub-make's CWD (test_kmods/) rather than the user's invocation directory. When O= is passed to kbuild, also pass KBUILD_OUTPUT=$(KMOD_O_VALID) explicitly. The parent invocation lifts KBUILD_OUTPUT into MAKEFLAGS as a command-line variable, which would otherwise suppress kbuild's own "KBUILD_OUTPUT := $(O)" assignment and cause it to use the inherited KBUILD_OUTPUT instead of the validated O=. Guard both all and clean against a missing KDIR so the step is silently skipped rather than fatal. Make the parent Makefile's cp conditional so it does not abort when modules were not built.

2026-06-05selftests/bpf: Add BPF_STRICT_BUILD toggleRicardo B. Marlière
Distro kernels often lack BTF types or kernel features required by some BPF selftests, causing the build to abort on the first failure and preventing the remaining tests from running. Add BPF_STRICT_BUILD (default 1) to control build failure tolerance. When set to 0, the PERMISSIVE make variable is assigned a non-empty value that subsequent Makefile rules use to make individual build steps non-fatal. When set to 1 (the default), the build fails on any error, preserving the existing behavior for CI and direct builds. Users can opt in to permissive mode on the command line: make -C tools/testing/selftests \ TARGETS=bpf SKIP_TARGETS= BPF_STRICT_BUILD=0 Suggested-by: Alan Maguire <alan.maguire@oracle.com> Signed-off-by: Ricardo B.

2026-06-04selftests: rds: support RDS built as loadable modulesAllison Henderson
Commit 92cc6708f4a2 ("selftests: rds: config: disable modules") set CONFIG_MODULES=n since run.sh required this kconfig. But disabling modules also forces every =m option to =n rather than =y, which can silently drop unrelated features. This patch removes CONFIG_MODULES=n from the rds selftest config and updates the check_*conf_enabled() routines to accept a config as either built-in (=y) or modular (=m). A new probe_module() function is added to load the backing module when a component is set to be modular (=m). config.sh no longer forces CONFIG_MODULES=n, so a user who follows the SKIP message to run config.sh does not silently end up with modules disabled again. rds.ko itself is auto-loaded on socket creation, and rds_rdma.ko is auto-loaded when SO_RDS_TRANSPORT is set with RDS_TRANS_IB, but the TCP transport (rds_tcp.ko) is not auto-loaded on the bind path, so the backing modules are loaded explicitly here.

The RDS selftests create AF_RDS sockets but never selects a transport, so the transport is chosen implicitly based on network topology when the socket is bound. If underlying connection establishment fails, RDS can fall back to another transport (e.g. loopback) and the test still passes, silently bypassing the intended datapath it is meant to exercise. Set SO_RDS_TRANSPORT to the proper RDS_TRANS_IB or RDS_TRANS_TCP before they are bound, so the test fails loudly if the intended transport is unavailable rather than passing on a different path.
