"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nLoongArch: Fix warnings during S3 suspend\n\nThe enable_gpe_wakeup() function calls acpi_enable_all_wakeup_gpes(),\nand the later one may call the preempt_schedule_common() function,\nresulting in a thread switch and causing the CPU to be in an interrupt\nenabled state after the enable_gpe_wakeup() function returns, leading\nto the warnings as follow.\n\n[ C0] WARNING: ... at kernel/time/timekeeping.c:845 ktime_get+0xbc/0xc8\n[ C0] ...\n[ C0] Call Trace:\n[ C0] [<90000000002243b4>] show_stack+0x64/0x188\n[ C0] [<900000000164673c>] dump_stack_lvl+0x60/0x88\n[ C0] [<90000000002687e4>] __warn+0x8c/0x148\n[ C0] [<90000000015e9978>] report_bug+0x1c0/0x2b0\n[ C0] [<90000000016478e4>] do_bp+0x204/0x3b8\n[ C0] [<90000000025b1924>] exception_handlers+0x1924/0x10000\n[ C0] [<9000000000343bbc>] ktime_get+0xbc/0xc8\n[ C0] [<9000000000354c08>] tick_sched_timer+0x30/0xb0\n[ C0] [<90000000003408e0>] __hrtimer_run_queues+0x160/0x378\n[ C0] [<9000000000341f14>] hrtimer_interrupt+0x144/0x388\n[ C0] [<9000000000228348>] constant_timer_interrupt+0x38/0x48\n[ C0] [<90000000002feba4>] __handle_irq_event_percpu+0x64/0x1e8\n[ C0] [<90000000002fed48>] handle_irq_event_percpu+0x20/0x80\n[ C0] [<9000000000306b9c>] handle_percpu_irq+0x5c/0x98\n[ C0] [<90000000002fd4a0>] generic_handle_domain_irq+0x30/0x48\n[ C0] [<9000000000d0c7b0>] handle_cpu_irq+0x70/0xa8\n[ C0] [<9000000001646b30>] handle_loongarch_irq+0x30/0x48\n[ C0] [<9000000001646bc8>] do_vint+0x80/0xe0\n[ C0] [<90000000002aea1c>] finish_task_switch.isra.0+0x8c/0x2a8\n[ C0] [<900000000164e34c>] __schedule+0x314/0xa48\n[ C0] [<900000000164ead8>] schedule+0x58/0xf0\n[ C0] [<9000000000294a2c>] worker_thread+0x224/0x498\n[ C0] [<900000000029d2f0>] kthread+0xf8/0x108\n[ C0] [<9000000000221f28>] ret_from_kernel_thread+0xc/0xa4\n[ C0]\n[ C0] ---[ end trace 0000000000000000 ]---\n\nThe root cause is acpi_enable_all_wakeup_gpes() uses a mutex to protect\nacpi_hw_enable_all_wakeup_gpes(), and acpi_ut_acquire_mutex() may cause\na thread switch. Since there is no longer concurrent execution during\nloongarch_acpi_suspend(), we can call acpi_hw_enable_all_wakeup_gpes()\ndirectly in enable_gpe_wakeup().\n\nThe solution is similar to commit 22db06337f590d01 (\"ACPI: sleep: Avoid\nbreaking S3 wakeup due to might_sleep()\")."
