Title
gpio: pch: use raw_spinlock_t for the register lock
Summary
In the Linux kernel, the following vulnerability has been resolved: gpio: pch: use raw_spinlock_t for the register lock pch_irq_type() is registered as the irq_chip .irq_set_type callback and takes chip->spinlock with spin_lock_irqsave(). This callback is reached from __setup_irq() -> __irq_set_trigger() -> chip->irq_set_type() while the caller holds desc->lock, a raw_spinlock_t, with hardirqs disabled. That context is not sleepable, but on PREEMPT_RT a regular spinlock_t is an rtmutex-backed sleeping lock, so acquiring it there is invalid. This was confirmed on a PREEMPT_RT kernel with lockdep (PROVE_RAW_LOCK_NESTING and DEBUG_ATOMIC_SLEEP). A grounded PoC mirrored pch_irq_type()'s locking and drove it through the real genirq carrier irq_set_irq_type() -> __irq_set_trigger() -> chip->irq_set_type(), i.e. the same __irq_set_trigger() edge that __setup_irq() takes for a requested IRQ. With the original spin_lock_irqsave() edge lockdep reported an invalid wait context, immediately followed by: BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48 in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 95, name: insmod hardirqs last disabled at (3784): _raw_spin_lock_irqsave+0x4f/0x60 rt_spin_lock+0x3a/0x1c0 repro_irq_set_type+0x64/0xa0 [pch_repro] __irq_set_trigger+0x69/0x140 irq_set_irq_type+0x78/0xd0 Switching the mirrored lock to raw_spinlock_t made both splats go away. Convert the register lock to raw_spinlock_t. The same lock also serializes the GPIO direction/value callbacks and the suspend/resume register save/restore, but all of those critical sections only perform MMIO register accesses (ioread32()/iowrite32()) and irq_set_handler_locked(); none of them contain sleepable operations. Keeping this register lock non-sleeping is therefore appropriate for the irqchip callbacks and does not change the GPIO-side locking contract. This is the same class of issue and fix as recently addressed for other GPIO controllers, e.g. commit 286533cb14a3 ("gpio: sch: use raw_spinlock_t in the irq startup path") and commit 90f0109019e6 ("gpio: eic-sprd: use raw_spinlock_t in the irq startup path").

            "value": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: pch: use raw_spinlock_t for the register lock\n\npch_irq_type() is registered as the irq_chip .irq_set_type callback and\ntakes chip-\u003espinlock with spin_lock_irqsave().  This callback is reached\nfrom __setup_irq() -\u003e __irq_set_trigger() -\u003e chip-\u003eirq_set_type() while\nthe caller holds desc-\u003elock, a raw_spinlock_t, with hardirqs disabled.\nThat context is not sleepable, but on PREEMPT_RT a regular spinlock_t is\nan rtmutex-backed sleeping lock, so acquiring it there is invalid.\n\nThis was confirmed on a PREEMPT_RT kernel with lockdep\n(PROVE_RAW_LOCK_NESTING and DEBUG_ATOMIC_SLEEP).  A grounded PoC mirrored\npch_irq_type()\u0027s locking and drove it through the real genirq carrier\nirq_set_irq_type() -\u003e __irq_set_trigger() -\u003e chip-\u003eirq_set_type(), i.e.\nthe same __irq_set_trigger() edge that __setup_irq() takes for a\nrequested IRQ.  With the original spin_lock_irqsave() edge lockdep\nreported an invalid wait context, immediately followed by:\n\n  BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48\n  in_atomic(): 1, irqs_disabled(): 1, non_block: 0, pid: 95, name: insmod\n  hardirqs last disabled at (3784): _raw_spin_lock_irqsave+0x4f/0x60\n   rt_spin_lock+0x3a/0x1c0\n   repro_irq_set_type+0x64/0xa0 [pch_repro]\n   __irq_set_trigger+0x69/0x140\n   irq_set_irq_type+0x78/0xd0\n\nSwitching the mirrored lock to raw_spinlock_t made both splats go away.\n\nConvert the register lock to raw_spinlock_t.  The same lock also\nserializes the GPIO direction/value callbacks and the suspend/resume\nregister save/restore, but all of those critical sections only perform\nMMIO register accesses (ioread32()/iowrite32()) and\nirq_set_handler_locked(); none of them contain sleepable operations.\nKeeping this register lock non-sleeping is therefore appropriate for the\nirqchip callbacks and does not change the GPIO-side locking contract.\n\nThis is the same class of issue and fix as recently addressed for other\nGPIO controllers, e.g. commit 286533cb14a3 (\"gpio: sch: use raw_spinlock_t\nin the irq startup path\") and commit 90f0109019e6 (\"gpio: eic-sprd: use\nraw_spinlock_t in the irq startup path\")."
