"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmd: fix array_state=clear sysfs deadlock\n\nWhen \"clear\" is written to array_state, md_attr_store() breaks sysfs\nactive protection so the array can delete itself from its own sysfs\nstore method.\n\nHowever, md_attr_store() currently drops the mddev reference before\ncalling sysfs_unbreak_active_protection(). Once do_md_stop(..., 0)\nhas made the mddev eligible for delayed deletion, the temporary\nkobject reference taken by sysfs_break_active_protection() can become\nthe last kobject reference protecting the md kobject.\n\nThat allows sysfs_unbreak_active_protection() to drop the last\nkobject reference from the current sysfs writer context. kobject\nteardown then recurses into kernfs removal while the current sysfs\nnode is still being unwound, and lockdep reports recursive locking on\nkn->active with kernfs_drain() in the call chain.\n\nReproducer on an existing level:\n1. Create an md0 linear array and activate it:\n mknod /dev/md0 b 9 0\n echo none > /sys/block/md0/md/metadata_version\n echo linear > /sys/block/md0/md/level\n echo 1 > /sys/block/md0/md/raid_disks\n echo \"$(cat /sys/class/block/sdb/dev)\" > /sys/block/md0/md/new_dev\n echo \"$(($(cat /sys/class/block/sdb/size) / 2))\" > \\\n\t/sys/block/md0/md/dev-sdb/size\n echo 0 > /sys/block/md0/md/dev-sdb/slot\n echo active > /sys/block/md0/md/array_state\n2. Wait briefly for the array to settle, then clear it:\n sleep 2\n echo clear > /sys/block/md0/md/array_state\n\nThe warning looks like:\n\n WARNING: possible recursive locking detected\n bash/588 is trying to acquire lock:\n (kn->active#65) at __kernfs_remove+0x157/0x1d0\n but task is already holding lock:\n (kn->active#65) at sysfs_unbreak_active_protection+0x1f/0x40\n ...\n Call Trace:\n kernfs_drain\n __kernfs_remove\n kernfs_remove_by_name_ns\n sysfs_remove_group\n sysfs_remove_groups\n __kobject_del\n kobject_put\n md_attr_store\n kernfs_fop_write_iter\n vfs_write\n ksys_write\n\nRestore active protection before mddev_put() so the extra sysfs\nkobject reference is dropped while the mddev is still held alive. The\nactual md kobject deletion is then deferred until after the sysfs\nwrite path has fully returned."
