[PATCH 2/2] atomic64: Use arch_spin_locks instead of raw_spin_locks

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> raw_spin_locks can be traced by lockdep or tracing itself. Atomic64 operations can be used in the tracing infrastructure. When an architecture does not have true atomic64 operations it can use the generic version that disables interrupts and uses spin_locks. The tracing ring buffer code uses atomic64 operations for the time keeping. But because some architectures use the default operations, the locking inside the atomic operations can cause an infinite recursion. As atomic64 is an architecture specific operation, it should not be using raw_spin_locks() but instead arch_spin_locks as that is the purpose of arch_spin_locks. To be used in architecture specific implementations of generic infrastructure like atomic64 operations.

[PATCH v2 1/1] iommu/vt-d: Make intel_iommu_drain_pasid_prq() cover faults for RID

by Lu Baolu

This driver supports page faults on PCI RID since commit <9f831c16c69e> ("iommu/vt-d: Remove the pasid present check in prq_event_thread") by allowing the reporting of page faults with the pasid_present field cleared to the upper layer for further handling. The fundamental assumption here is that the detach or replace operations act as a fence for page faults. This implies that all pending page faults associated with a specific RID or PASID are flushed when a domain is detached or replaced from a device RID or PASID. However, the intel_iommu_drain_pasid_prq() helper does not correctly handle faults for RID. This leads to faults potentially remaining pending in the iommu hardware queue even after the domain is detached, thereby violating the aforementioned assumption. Fix this issue by extending intel_iommu_drain_pasid_prq() to cover faults for RID.

[PATCH net] net/rose: prevent integer overflows in rose_setsockopt()

by Nikita Zhandarovich

In case of possible unpredictably large arguments passed to rose_setsockopt() and multiplied by extra values on top of that, integer overflows may occur.

Also, switch to unsigned int and remove useless check for negative 'opt' in ROSE_IDLE case. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.

[PATCH v3] perf bench: Fix undefined behavior in cmpworker()

by Kuan-Wei Chiu

The comparison function cmpworker() violates the C standard's requirements for qsort() comparison functions, which mandate symmetry and transitivity: Symmetry: If x < y, then y > x. Transitivity: If x < y and y < z, then x < z. In its current implementation, cmpworker() incorrectly returns 0 when w1->tid < w2->tid, which breaks both symmetry and transitivity. This violation causes undefined behavior, potentially leading to issues such as memory corruption in glibc [1]. Fix the issue by returning -1 when w1->tid < w2->tid, ensuring compliance with the C standard and preventing undefined behavior.
