      fsnotify: move events should indicate the event was on a child · ff52cc21
      Eric Paris authored
      fsnotify tells its listeners explicitly when an event happened on the given
      inode verses on the child of the given inode.  (see __fsnotify_parent)
      However, the semantics of fsnotify_move() are such that we deliver events
      directly to the two parent directories in question (old_dir and new_dir)
      directly without using the __fsnotify_parent() call.  fsnotify should be
      adding FS_EVENT_ON_CHILD for the notifications to these parents.

      fsnotify: fsnotify marks on inodes pin them in core · 1ef5f13c
      Eric Paris authored
      This patch pins any inodes with an fsnotify mark in core.  The idea is that
      as soon as the mark is removed from the inode->fsnotify_mark_entries list
      the inode will be iput.  In reality is doesn't quite work exactly this way.
      The igrab will happen when the mark is added to an inode, but the iput will
      happen when the inode pointer is NULL'd inside the mark.
      
      It's possible that 2 racing things will try to remove the mark from
      different directions.  One may try to remove the mark because of an
      explicit request and one might try to remove it because the inode was
      deleted.  It's possible that the removal because of inode deletion will
      remove the mark from the inode's list, but the removal by explicit request
      will actually set entry->inode == NULL; and call the iput.  This is safe.

      fsnotify: add marks to inodes so groups can interpret how to handle those inodes · 3be25f49
      Eric Paris authored
      This patch creates a way for fsnotify groups to attach marks to inodes.
      These marks have little meaning to the generic fsnotify infrastructure
      and thus their meaning should be interpreted by the group that attached
      them to the inode's list.
      
      dnotify and inotify  will make use of these markings to indicate which
      inodes are of interest to their respective groups.  But this implementation
      has the useful property that in the future other listeners could actually
      use the marks for the exact opposite reason, aka to indicate which inodes
      it had NO interest in.

      fsnotify: unified filesystem notification backend · 90586523
      Eric Paris authored
      fsnotify is a backend for filesystem notification.  fsnotify does
      not provide any userspace interface but does provide the basis
      needed for other notification schemes such as dnotify.  fsnotify
      can be extended to be the backend for inotify or the upcoming
      fanotify.  fsnotify provides a mechanism for "groups" to register for
      some set of filesystem events and to then deliver those events to
      those groups for processing.
      
      fsnotify has a number of benefits, the first being actually shrinking the size
      of an inode.  Before fsnotify to support both dnotify and inotify an inode had
      
              unsigned long           i_dnotify_mask; /* Directory notify events */
              struct dnotify_struct   *i_dnotify; /* for directory notifications */
              struct list_head        inotify_watches; /* watches on this inode */
              struct mutex            inotify_mutex;  /* protects the watches list
      
      But with fsnotify this same functionallity (and more) is done with just
      
              __u32                   i_fsnotify_mask; /* all events for this inode */
              struct hlist_head       i_fsnotify_mark_entries; /* marks on this inode */
      
      That's right, inotify, dnotify, and fanotify all in 64 bits.  We used that
      much space just in inotify_watches alone, before this patch set.
      
      fsnotify object lifetime and locking is MUCH better than what we have today.
      inotify locking is incredibly complex.  See 8f7b0ba1 as an example of
      what's been busted since inception.  inotify needs to know internal semantics
      of superblock destruction and unmounting to function.  The inode pinning and
      vfs contortions are horrible.
      
      no fsnotify implementers do allocation under locks.  This means things like
      f04b30de which (due to an overabundance of caution) changes GFP_KERNEL to
      GFP_NOFS can be reverted.  There are no longer any allocation rules when using
      or implementing your own fsnotify listener.
      
      fsnotify paves the way for fanotify.  In brief fanotify is a notification
      mechanism that delivers the lisener both an 'event' and an open file descriptor
      to the object in question.  This means that fanotify is pathname agnostic.
      Some on lkml may not care for the original companies or users that pushed for
      TALPA, but fanotify was designed with flexibility and input for other users in
      mind.  The readahead group expressed interest in fanotify as it could be used
      to profile disk access on boot without breaking the audit system.  The desktop
      search groups have also expressed interest in fanotify as it solves a number
      of the race conditions and problems present with managing inotify when more
      than a limited number of specific files are of interest.  fanotify can provide
      for a userspace access control system which makes it a clean interface for AV
      vendors to hook without trying to do binary patching on the syscall table,
      LSM, and everywhere else they do their things today.  With this patch series
      fanotify can be implemented in less than 1200 lines of easy to review code.
      Almost all of which is the socket based user interface.
      
      This patch series builds fsnotify to the point that it can implement
      dnotify and inotify_user.  Patches exist and will be sent soon after
      acceptance to finish the in kernel inotify conversion (audit) and implement
      fanotify.
