Subject: [PATCH 0/8] perf/x86: Miscellaneous PMU bug fixes
Date: Fri, 5 Jun 2026 09:11:28 +0800 [thread overview]
Message-ID: <20260605011136.2043393-1-dapeng1.mi@linux.intel.com> (raw)
This series groups several independent PMU fixes to simplify review and
backporting.
Patch layout:
- Patch 1/8: Fix anythread_deprecated being overwritten issue.
- Patches 2-3/8: Fix the issue that cap_user_rdpmc is not updated
correctly.
- Patches 4-5/8: Fix a kernel address leakage issue in LBR stack.
- Patch 6/8: Fix the issue that the return value of
intel_pmu_init_hybrid() is not valiated correctly.
- Patch 7/8: Fix a "unchecked MSR access error" on PEBS_ENABLE MSR.
- Patch 8/8: Prevent a theoretical kernel register data leak in sampling.
Dapeng Mi (7):
perf/x86/intel: Remove anythread_deprecated bit from perf_capabilities
perf/x86: Update cap_user_rdpmc base on rdpmc user disable state
perf/x86/intel: Fix redundant branch type check in
intel_pmu_lbr_filter()
perf/x86/intel: Fix kernel address leakages in LBR stack
perf/x86/intel: Validate return value of intel_pmu_init_hybrid()
perf/x86/intel: Drop fixed-counter PEBS constraints for baseline PEBS
perf/core: Fix kernel register info leak via hardware skid
Ian Rogers (1):
perf/x86: Introduce is_x86_pmu() helper
