| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\naoe: avoid potential deadlock at set_capacity\n\nMove set_capacity() outside of the section procected by (&d->lock).\nTo avoid possible interrupt unsafe locking scenario:\n\n CPU0 CPU1\n ---- ----\n[1] lock(&bdev->bd_size_lock);\n local_irq_disable();\n [2] lock(&d->lock);\n [3] lock(&bdev->bd_size_lock);\n <Interrupt>\n[4] lock(&d->lock);\n\n *** DEADLOCK ***\n\nWhere [1](&bdev->bd_size_lock) hold by zram_add()->set_capacity().\n[2]lock(&d->lock) hold by aoeblk_gdalloc(). And aoeblk_gdalloc()\nis trying to acquire [3](&bdev->bd_size_lock) at set_capacity() call.\nIn this situation an attempt to acquire [4]lock(&d->lock) from\naoecmd_cfg_rsp() will lead to deadlock.\n\nSo the simplest solution is breaking lock dependency\n[2](&d->lock) -> [3](&bdev->bd_size_lock) by moving set_capacity()\noutside." |
