kernel-selftest: do not run 'make clean'

2026-06-09T14:26:33+00:00

Due to the way the kernel-selftest sources are set up, the toplevel Makefile does not work and `make clean` will always result in a "The source tree is not clean, please run 'make ARCH=... mrproper'" error. Avoid running it by setting CLEANBROKEN = "1", so rebuilding the recipe without a clean (which often happens when the kernel has changed) does not fail.

kernel-selftest: add generic architecture-independent self-tests

2026-06-08T01:21:52+00:00

Add generic kernel self-tests that build cleanly with mainline kernel (6.18+), work on all architectures, and either PASS or SKIP gracefully at runtime. Tests added: - acct: BSD process accounting - breakpoints: hardware breakpoint handling - cachestat: page cache statistics (cachestat syscall) - cgroup: control group v1 interface - clone3: clone3 syscall with flags - core: syscalls like close_range, unshare - coredump: core dump generation - dmabuf-heaps: DMA-BUF heap allocator - efivarfs: EFI variable filesystem - filelock: POSIX file locking (OFD locks) - filesystems: basic filesystem operations - filesystems/binderfs: Android Binder IPC (skips if CONFIG_ANDROID_BINDERFS=n) - filesystems/epoll: epoll syscall extensions - fpu: floating-point unit state - ftrace: function tracer interface - futex: fast userspace mutex - gpio: general purpose I/O - ipc: System V IPC primitives - kcmp: compare kernel resource identifiers - kvm: kernel-based virtual machine - landlock: LSM sandboxing (skips if CONFIG_SECURITY_LANDLOCK=n) - locking: ww_mutex deadlock avoidance - lsm: Linux Security Module interface - membarrier: memory barrier syscalls - mincore: mincore syscall (page residency) - mount: mount syscall (unprivileged variants) - mount_setattr: mount attribute syscall - move_mount_set_group: move_mount peer group - mseal_system_mappings: system mapping sealing - namespaces: PID/UTS/IPC/mount/network namespaces - net: networking stack - net/mptcp: multipath TCP - pidfd: pidfd-based process management - pid_namespace: PID namespace limits - proc: /proc filesystem interface - ptrace: process tracing - rlimits: resource limits - rseq: restartable sequences - sched: scheduler and real-time classes - seccomp: secure computing mode - signal: signal handling - size: ELF size utilities - splice: zero-copy data transfers - sync: cache synchronization - syscall_user_dispatch: user-space syscall dispatch - sysctl: sysctl interface - tc-testing: traffic control - timens: time namespaces - tmpfs: tmpfs filesystem - tpm2: Trusted Platform Module 2.0 - tty: TTY layer - uevent: kernel uevent subsystem - user_events: tracepoint user interface - vDSO: virtual dynamic shared object - watchdog: hardware watchdog timer - zram: compressed RAM block device Tested on aarch64 device BeaglePlay(AM6254 SoC): - Tests either PASS or SKIP gracefully Depends-on: kernel-selftest: add libcap to build and runtime dependencies Signed-off-by: Telukula Jeevan Kumar Sahu Signed-off-by: Khem Raj

kernel-selftest: add libcap to build and runtime dependencies

2026-06-08T01:21:51+00:00

libcap is needed unconditionally for capability-aware tests such as breakpoints, cgroup, clone3, futex, ptrace, and seccomp. Add it to DEPENDS so it is always available at build time and to RDEPENDS so the installed tests can call cap_get_proc() and friends at runtime. bash and libgcc are also added to RDEPENDS: bash is required by several test shell scripts, and libgcc provides libgcc_s.so needed by tests that use GCC-emitted unwinding stubs.

kernel-selftest: add missing sources if mm is enabled

2026-04-20T14:35:38+00:00

Some headers come from 'mm' (in the top source directory, i.e. the root of Linux's sources), as in the exampels below: Makefile:LOCAL_HDRS += $(selfdir)/mm/local_config.h $(top_srcdir)/mm/gup_test.h cow.c:#include "../../../../mm/gup_test.h" gup_longterm.c:#include "../../../../mm/gup_test.h" gup_test.c:#include hmm-tests.c:#include uffd-unit-tests.c:#include "../../../../mm/gup_test.h" Add this directory to KERNEL_SELFTEST_SRC if 'mm' PACKAGECONFIG is enabled.

kernel-selftest: fix mm selftests dependencies

2026-04-20T14:35:38+00:00

Add numa (numactl), as required by rmap, migration, and others. Add liburing, otherwise some tests would be disabled. Moreover, liburing's availability is checked in a shell script executed prior to the compilation of the individual test cases. This script, however, does not read CFLAGS. Backport a fix [1] from mainline to address this issue. [1] https://github.com/torvalds/linux/commit/7f532d19c8be76ad2fcd7ab6b0c9eb618f70966b Signed-off-by: João Marcos Costa Signed-off-by: Khem Raj

kernel-selftest: drop libhugetlbfs

2026-04-20T14:35:38+00:00

The support of libhugetlbfs was removed from mainline Linux a while ago, since v6.1 [1]. Since libhugetlbfs was the main reason to remove 'mm' selftests for some specific architectures, the respective operations should only remove bpf. Update the recipe to remove libhugetlbfs as a dependency of mm, and thus unblock this test category for some targets.

kernel-selftest: rename vm selftests to mm

2026-04-20T14:35:38+00:00

Since v6.10 [1], this category of selftests was renamed to 'mm'. Update the recipe accordingly. I left a mention to the previous name (i.e., 'vm') just in case.

kernel-selftest: handle missing -64.h headers

2025-08-28T14:56:01+00:00

Some toolchains ship only bits/*.h without the -64.h suffix, causing the recipe to fail. Add a fallback to use *.h if *-64.h is not found, and warn if neither exists. Signed-off-by: Nylon Chen Signed-off-by: Joao Marcos Costa Signed-off-by: Khem Raj

kernel-selftest: Fix PTP selftest compilation for kernel 6.7+

2025-07-09T16:16:08+00:00

The PTP selftest fails to compile with kernel versions 6.7+ due to missing header definitions for PTP_MASK_CLEAR_ALL and PTP_MASK_EN_SINGLE. These definitions were introduced in kernel v6.7 with commit c5a445b. This fix adds kernel headers to CFLAGS during compilation to ensure the required definitions are available.
