| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nfsnotify: clear PARENT_WATCHED flags lazily\n\nIn some setups directories can have many (usually negative) dentries.\nHence __fsnotify_update_child_dentry_flags() function can take a\nsignificant amount of time. Since the bulk of this function happens\nunder inode->i_lock this causes a significant contention on the lock\nwhen we remove the watch from the directory as the\n__fsnotify_update_child_dentry_flags() call from fsnotify_recalc_mask()\nraces with __fsnotify_update_child_dentry_flags() calls from\n__fsnotify_parent() happening on children. This can lead upto softlockup\nreports reported by users.\n\nFix the problem by calling fsnotify_update_children_dentry_flags() to\nset PARENT_WATCHED flags only when parent starts watching children.\n\nWhen parent stops watching children, clear false positive PARENT_WATCHED\nflags lazily in __fsnotify_parent() for each accessed child." |
