Mon, 11 May 2026 19:45:57 +0200

selftests/bpf: Add tests for wakeup_sources kfuncsIntroduce a set of BPF selftests to verify the safety and functionalityof wakeup_source kfuncs.The suite includes:1. A functional test (test_wakeup_source.c) that iterates over the global wakeup_sources list. It uses CO-RE to read timing statistics and validates them in user-space via the BPF ring buffer.2. A negative test suite (wakeup_source_fail.c) ensuring the BPF verifier correctly enforces reference tracking and type safety.3. Enable CONFIG_PM_WAKELOCKS in the test config, allowing creation of wakeup sources via /sys/power/wake_lock.A shared header (wakeup_source.h) is introduced to ensure consistentmemory layout for the Ring Buffer data between BPF and user-space.Signed-off-by: Samuel Wu Link: https://lore.kernel.org/r/20260511174559.659782-3-wusamuel@google.comSigned-off-by: Alexei Starovoitov List of files: /linux/tools/testing/selftests/bpf/config

e700f5d1560798aacf0e56fdcc70ee2c20bf56ec - watchdog: softlockup: panic when lockup duration exceeds N thresholds

Tue, 16 Dec 2025 08:45:21 +0100

watchdog: softlockup: panic when lockup duration exceeds N thresholdsThe softlockup_panic sysctl is currently a binary option: panicimmediately or never panic on soft lockups.Panicking on any soft lockup, regardless of duration, can be overlyaggressive for brief stalls that may be caused by legitimate operations. Conversely, never panicking may allow severe system hangs to persistundetected.Extend softlockup_panic to accept an integer threshold, allowing thekernel to panic only when the normalized lockup duration exceeds Nwatchdog threshold periods. This provides finer-grained control todistinguish between transient delays and persistent system failures.The accepted values are:- 0: Don't panic (unchanged)- 1: Panic when duration >= 1 * threshold (20s default, original behavior)- N > 1: Panic when duration >= N * threshold (e.g., 2 = 40s, 3 = 60s.)The original behavior is preserved for values 0 and 1, maintaining fullbackward compatibility while allowing systems to tolerate brief lockupswhile still catching severe, persistent hangs.[lirongqing@baidu.com: v2] Link: https://lkml.kernel.org/r/20251218074300.4080-1-lirongqing@baidu.comLink: https://lkml.kernel.org/r/20251216074521.2796-1-lirongqing@baidu.comSigned-off-by: Li RongQing Cc: Eduard Zingerman Cc: Hao Luo Cc: Jiri Olsa Cc: John Fastabend Cc: KP Singh Cc: Lance Yang Cc: Martin KaFai Lau Cc: Nicholas Piggin Cc: Song Liu Cc: Stanislav Fomichev Cc: Yonghong Song Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/bpf/config

selftests/bpf: Add tests for livepatch + bpf trampolineBoth livepatch and BPF trampoline use ftrace. Special attention is neededwhen livepatch and fexit program touch the same function at the sametime, because livepatch updates a kernel function and the BPF trampolineneed to call into the right version of the kernel function.Use samples/livepatch/livepatch-sample.ko for the test.The test covers two cases: 1) When a fentry program is loaded first.
