      "title": "sched_ext: Preserve rq tracking across local DSQ dispatch",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched_ext: Preserve rq tracking across local DSQ dispatch\n\ndispatch_to_local_dsq() can run from scx_bpf_dsq_move_to_local() while\nops.dispatch() has recorded the current rq. Moving a task to a local DSQ\nmay switch to the source or destination rq before synchronously invoking\nops.dequeue() through the following path:\n\n  SCX_CALL_OP(dispatch, rq)\n    ops.dispatch()\n      scx_bpf_dsq_move_to_local()\n        scx_flush_dispatch_buf()\n          finish_dispatch()\n            dispatch_to_local_dsq()\n              scx_dispatch_enqueue()\n                local_dsq_post_enq()\n                  call_task_dequeue()\n                    SCX_CALL_OP_TASK(dequeue, locked_rq, ...)\n\nThe nested callback saves the recorded rq and restores it on return. If\nthe rq tracking does not follow the lock switch, update_locked_rq() can\ntrigger the following lockdep assertion while restoring an rq which is\nno longer held:\n\n  WARNING: kernel/sched/sched.h:1641 at call_task_dequeue+0x160/0x170\n  Call Trace:\n    scx_dispatch_enqueue+0x2b0/0x460\n    dispatch_to_local_dsq+0x138/0x230\n    scx_flush_dispatch_buf+0x1af/0x220\n    scx_bpf_dsq_move_to_local___v2+0xe2/0x1c0\n    bpf__sched_ext_ops_dispatch+0x4b/0xa7\n    do_pick_task_scx+0x3b6/0x910\n    __pick_next_task+0x105/0x1f0\n    __schedule+0x3e7/0x1980\n\nIntroduce switch_rq_lock() to update the tracking state together with\neach rq lock handoff. Use it in dispatch_to_local_dsq(),\nmove_remote_task_to_local_dsq() and the in-balance paths of\nscx_dsq_move(), ensuring that scx_locked_rq() consistently refers to the\nrq whose lock is actually held throughout the lock dance.",
