Title
io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work
Summary
In the Linux kernel, the following vulnerability has been resolved: io_uring/sqpoll: ensure task state is TASK_RUNNING when running task_work When the sqpoll is exiting and cancels pending work items, it may need to run task_work. If this happens from within io_uring_cancel_generic(), then it may be under waiting for the io_uring_task waitqueue. This results in the below splat from the scheduler, as the ring mutex may be attempted grabbed while in a TASK_INTERRUPTIBLE state. Ensure that the task state is set appropriately for that, just like what is done for the other cases in io_run_task_work(). do not call blocking ops when !TASK_RUNNING; state=1 set at [<0000000029387fd2>] prepare_to_wait+0x88/0x2fc WARNING: CPU: 6 PID: 59939 at kernel/sched/core.c:8561 __might_sleep+0xf4/0x140 Modules linked in: CPU: 6 UID: 0 PID: 59939 Comm: iou-sqp-59938 Not tainted 6.12.0-rc3-00113-g8d020023b155 #7456 Hardware name: linux,dummy-virt (DT) pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) pc : __might_sleep+0xf4/0x140 lr : __might_sleep+0xf4/0x140 sp : ffff80008c5e7830 x29: ffff80008c5e7830 x28: ffff0000d93088c0 x27: ffff60001c2d7230 x26: dfff800000000000 x25: ffff0000e16b9180 x24: ffff80008c5e7a50 x23: 1ffff000118bcf4a x22: ffff0000e16b9180 x21: ffff0000e16b9180 x20: 000000000000011b x19: ffff80008310fac0 x18: 1ffff000118bcd90 x17: 30303c5b20746120 x16: 74657320313d6574 x15: 0720072007200720 x14: 0720072007200720 x13: 0720072007200720 x12: ffff600036c64f0b x11: 1fffe00036c64f0a x10: ffff600036c64f0a x9 : dfff800000000000 x8 : 00009fffc939b0f6 x7 : ffff0001b6327853 x6 : 0000000000000001 x5 : ffff0001b6327850 x4 : ffff600036c64f0b x3 : ffff8000803c35bc x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff0000e16b9180 Call trace: __might_sleep+0xf4/0x140 mutex_lock+0x84/0x124 io_handle_tw_list+0xf4/0x260 tctx_task_work_run+0x94/0x340 io_run_task_work+0x1ec/0x3c0 io_uring_cancel_generic+0x364/0x524 io_sq_thread+0x820/0x124c ret_from_fork+0x10/0x20
