Add a test that implements a BPF program writing to a test map, which is attached to RTLA via --bpf-action to be executed on theshold overflow. A combination of --on-threshold shell with bpftool (which is always present if BPF support is enabled) is used to check whether the BPF program has executed successfully.

Add option --bpf-action that allows the user to attach an external BPF program that will be executed via BPF tail call on latency threshold overflow. Executing additional BPF code on latency threshold overflow allows doing low-latency and in-kernel troubleshooting of the cause of the overflow. The option takes an argument, which is a path to a BPF ELF file expected to contain a function named "action_handler" in a section named "tp/timerlat_action" (the section is necessary for libbpf to assign the correct BPF program type to it).

2026-01-07tools/rtla: Add common_usage()Costa Shulyupin6-64/+81
The rtla tools have significant code quadruplication in their usage functions. Each tool implements its own version of the same help text formatting and option descriptions, leading to maintenance overhead and inconsistencies. Documentation/tools/rtla/common_options.rst lists 14 common options. Add common_usage() infrastructure to consolidate help formatting. Subsequent patches will extend this to handle other common options. The refactored output is almost identical to the original, with the following changes: - add square brackets to specify optionality: `usage: [rtla] ...` - remove `-q` from timerlat hist because hist tools don't support it - minor spacing Signed-off-by: Costa Shulyupin <costa.shul@redhat.com> Link: https://lore.kernel.org/r/20251124063204.845425-1-costa.shul@redhat.com Signed-off-by: Tomas Glozar <tglozar@redhat.com>
2026-01-07rtla: Set stop threshold after all instances are enabledCrystal Wood5-37/+38
This avoids startup races where one of the instances hit a threshold before all instances were enabled, and thus tracing stops without the relevant event. In particular, this is not uncommon with the tests that set a very tight threshold and then complain if there's no analysis. This also ensures that we don't stop tracing during a warmup. The downside is a small chance of having an event over the threshold early in the output, without stopping on it, which could cause user confusion. This should be less likely if the warmup feature is used, but that doesn't eliminate the race window, just the odds of an unusual spike right at that moment.

2025-12-31kselftest/harness: Use helper to avoid zero-size memset warningWake Liu1-1/+7
When building kselftests with a toolchain that enables source fortification (e.g., Android's build environment, which uses -D_FORTIFY_SOURCE=3), a build failure occurs in tests that use an empty FIXTURE(). The root cause is that an empty fixture struct results in `sizeof(self_private)` evaluating to 0. The compiler's fortification checks then detect the `memset()` call with a compile-time constant size of 0, issuing a `-Wuser-defined-warnings` which is promoted to an error by `-Werror`. An initial attempt to guard the call with `if (sizeof(self_private) > 0)` was insufficient. The compiler's static analysis is aggressive enough to flag the `memset(..., 0)` pattern before evaluating the conditional, thus still triggering the error. To resolve this robustly, this change introduces a `static inline` helper function, `__kselftest_memset_safe()`. This function wraps the size check and the `memset()` call. By replacing the direct `memset()` in the `__TEST_F_IMPL` macro with a call to this helper, we create an abstraction boundary. This prevents the compiler's static analyzer from "seeing" the problematic pattern at the macro expansion site, resolving the build failure. Build Context: Compiler: Android (14488419, +pgo, +bolt, +lto, +mlgo, based on r584948) clang version 22.0.0 (https://android.googlesource.com/toolchain/llvm-project 2d65e4108033380e6fe8e08b1f1826cd2bfb0c99) Relevant Options: -O2 -Wall -Werror -D_FORTIFY_SOURCE=3 -target i686-linux-android10000 Test: m kselftest_futex_futex_requeue_pi Removed Gerrit Change-Id Shuah Khan <skhan@linuxfoundation.org> Link: https://lore.kernel.org/r/20251224084120.249417-1-wakel@google.com Signed-off-by: Wake Liu <wakel@google.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

2025-12-28selftests/ublk: add test for async partition scanMing Lei3-4/+81
Add test_generic_15.sh to verify that async partition scan prevents IO hang when reading partition tables. The test creates ublk devices with fault_inject target and very large delay (60s) to simulate blocked partition table reads, then kills the daemon to verify proper state transitions without hanging: 1. Without recovery support: - Create device with fault_inject and 60s delay - Kill daemon while partition scan may be blocked - Verify device transitions to DEAD state 2. With recovery support (-r 1): - Create device with fault_inject, 60s delay, and recovery - Kill daemon while partition scan may be blocked - Verify device transitions to QUIESCED state Before the async partition scan fix, killing the daemon during partition scan would cause deadlock as partition scan held ub->mutex while waiting for IO. With the async fix, partition scan happens in a work function and flush_work() ensures proper synchronization. Add _add_ublk_dev_no_settle() helper function to skip udevadm settle, which would otherwise hang waiting for partition scan events to complete when partition table read is delayed.
