KERNEL RC1 FIXES LAND ACROSS IRQ, X86, AND PERF SUBSYSTEMS
By RepoJournal · Filed · About Linux
Linus pulled five urgent fix sets overnight addressing resource leaks in irqchip drivers, an out-of-bounds vulnerability in Intel SNC resctrl code, and critical perf events regressions.
The irqchip fixes [1] tackle three driver-level issues: a resource leak in RISC-V imsic-early, an OF node reference leak in ARM gic-v3-its, and a dangling handler bug in the TS-4800 board driver that surfaces on module removal. The x86 fix [2] prevents out-of-bounds CPU offlining access when Intel Sub-NUMA Clustering is enabled in resctrl, a hardware resource control subsystem hitting production systems. Perf events [3] landed fixes for remove_on_exec handling in group events, uprobes CALL emulation with shadow stacks, and an uprobes unregister regression. The locking team [4] reverted an overzealous futex-requeue deadlock detection patch that introduced regressions, restoring the previous behavior. SPI fixes [5] are minor and device-specific, including Renesas DT binding improvements for power domains.
