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.

minicoredumper: upgrade 2.0.7 -> 2.0.8

2026-06-08T01:21:47+00:00

Upgrade minicoredumper from 2.0.7 to 2.0.8. Remove below patches because they have been merged by 2.0.8 upstream version: 0001-corestripper-Fix-uninitialized-warning.patch 0002-Fix-2038-year-problem-in-timestamp-handling.patch 0001-coreinject-fix-assignment-of-const-qualified-type.patch Changelog: =========== * Address multiple compiler warnings and errors found by more recent toolchains. The issues existed technically, but were not a problem for real-world usage scenarios. * Relocate the man pages for sbin binaries to section 8. * Fix timestamp value in the core dump directory name for 32-bit systems with a 64-bit time_t definition after 2038-01-19. * Improve status query for init script to check core_pattern usage and handle when the regd daemon is not enabled. * Known problems: - If tar is active, core files larger than 8GB will be truncated. If it is known that the core files will be >8GB and the full core file is needed, tar must be disabled. License-Update: The COPYING changes in upstream commit 941079541a update Copyright end dates to reflect when changes were last committed. The COPYING.LGPLv2.1 change in upstream commit 00e3b2fdf7 replaces the FSF postal mailing address with a URL as recommended by the GNU FAQ. No license change, no impact on the recipe licensing.

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.
