"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nblock: Remove queue freezing from several sysfs store callbacks\n\nFreezing the request queue from inside sysfs store callbacks may cause a\ndeadlock in combination with the dm-multipath driver and the\nqueue_if_no_path option. Additionally, freezing the request queue slows\ndown system boot on systems where sysfs attributes are set synchronously.\n\nFix this by removing the blk_mq_freeze_queue() / blk_mq_unfreeze_queue()\ncalls from the store callbacks that do not strictly need these callbacks.\nAdd the __data_racy annotation to request_queue.rq_timeout to suppress\nKCSAN data race reports about the rq_timeout reads.\n\nThis patch may cause a small delay in applying the new settings.\n\nFor all the attributes affected by this patch, I/O will complete\ncorrectly whether the old or the new value of the attribute is used.\n\nThis patch affects the following sysfs attributes:\n* io_poll_delay\n* io_timeout\n* nomerges\n* read_ahead_kb\n* rq_affinity\n\nHere is an example of a deadlock triggered by running test srp/002\nif this patch is not applied:\n\ntask:multipathd\nCall Trace:\n <TASK>\n __schedule+0x8c1/0x1bf0\n schedule+0xdd/0x270\n schedule_preempt_disabled+0x1c/0x30\n __mutex_lock+0xb89/0x1650\n mutex_lock_nested+0x1f/0x30\n dm_table_set_restrictions+0x823/0xdf0\n __bind+0x166/0x590\n dm_swap_table+0x2a7/0x490\n do_resume+0x1b1/0x610\n dev_suspend+0x55/0x1a0\n ctl_ioctl+0x3a5/0x7e0\n dm_ctl_ioctl+0x12/0x20\n __x64_sys_ioctl+0x127/0x1a0\n x64_sys_call+0xe2b/0x17d0\n do_syscall_64+0x96/0x3a0\n entry_SYSCALL_64_after_hwframe+0x4b/0x53\n </TASK>\ntask:(udev-worker)\nCall Trace:\n <TASK>\n __schedule+0x8c1/0x1bf0\n schedule+0xdd/0x270\n blk_mq_freeze_queue_wait+0xf2/0x140\n blk_mq_freeze_queue_nomemsave+0x23/0x30\n queue_ra_store+0x14e/0x290\n queue_attr_store+0x23e/0x2c0\n sysfs_kf_write+0xde/0x140\n kernfs_fop_write_iter+0x3b2/0x630\n vfs_write+0x4fd/0x1390\n ksys_write+0xfd/0x230\n __x64_sys_write+0x76/0xc0\n x64_sys_call+0x276/0x17d0\n do_syscall_64+0x96/0x3a0\n entry_SYSCALL_64_after_hwframe+0x4b/0x53\n </TASK>"
