      fs: rely on ->iterate_shared to determine f_pos locking · 7d84d1b9
      Christian Brauner authored
      Now that we removed ->iterate we don't need to check for either
      ->iterate or ->iterate_shared in file_needs_f_pos_lock(). Simply check
      for ->iterate_shared instead. This will tell us whether we need to
      unconditionally take the lock. Not just does it allow us to avoid
      checking f_inode's mode it also actually clearly shows that we're
      locking because of readdir.

      vfs: get rid of old '->iterate' directory operation · 3e327154
      Linus Torvalds authored
      All users now just use '->iterate_shared()', which only takes the
      directory inode lock for reading.
      
      Filesystems that never got convered to shared mode now instead use a
      wrapper that drops the lock, re-takes it in write mode, calls the old
      function, and then downgrades the lock back to read mode.
      
      This way the VFS layer and other callers no longer need to care about
      filesystems that never got converted to the modern era.
      
      The filesystems that use the new wrapper are ceph, coda, exfat, jfs,
      ntfs, ocfs2, overlayfs, and vboxsf.
      
      Honestly, several of them look like they really could just iterate their
      directories in shared mode and skip the wrapper entirely, but the point
      of this change is to not change semantics or fix filesystems that
      haven't been fixed in the last 7+ years, but to finally get rid of the
      dual iterators.

      proc: fix missing conversion to 'iterate_shared' · 0a2c2baa
      Linus Torvalds authored
      I'm looking at the directory handling due to the discussion about f_pos
      locking (see commit 79796425: "file: reinstate f_pos locking
      optimization for regular files"), and wanting to clean that up.
      
      And one source of ugliness is how we were supposed to move filesystems
      over to the '->iterate_shared()' function that only takes the inode lock
      for reading many many years ago, but several filesystems still use the
      bad old '->iterate()' that takes the inode lock for exclusive access.
      
      See commit 61922694 ("introduce a parallel variant of ->iterate()")
      that also added some documentation stating
      
            Old method is only used if the new one is absent; eventually it will
            be removed.  Switch while you still can; the old one won't stay.
      
      and that was back in April 2016.  Here we are, many years later, and the
      old version is still clearly sadly alive and well.
      
      Now, some of those old style iterators are probably just because the
      filesystem may end up having per-inode mutable data that it uses for
      iterating a directory, but at least one case is just a mistake.
      
      Al switched over most filesystems to use '->iterate_shared()' back when
      it was introduced.  In particular, the /proc filesystem was converted as
      one of the first ones in commit f50752ea ("switch all procfs
      directories ->iterate_shared()").
      
      But then later one new user of '->iterate()' was then re-introduced by
      commit 6d9c939d ("procfs: add smack subdir to attrs").
      
      And that's clearly not what we wanted, since that new case just uses the
      same 'proc_pident_readdir()' and 'proc_pident_lookup()' helper functions
      that other /proc pident directories use, and they are most definitely
      safe to use with the inode lock held shared.
      
      So just fix it.
      
      This still leaves a fair number of oddball filesystems using the
      old-style directory iterator (ceph, coda, exfat, jfs, ntfs, ocfs2,
      overlayfs, and vboxsf), but at least we don't have any remaining in the
      core filesystems.
      
      I'm going to add a wrapper function that just drops the read-lock and
      takes it as a write lock, so that we can clean up the core vfs layer and
      make all the ugly 'this filesystem needs exclusive inode locking' be
      just filesystem-internal warts.
      
      I just didn't want to make that conversion when we still had a core user
      left.

      open: make RESOLVE_CACHED correctly test for O_TMPFILE · a0fc452a
      Aleksa Sarai authored
      O_TMPFILE is actually __O_TMPFILE|O_DIRECTORY. This means that the old
      fast-path check for RESOLVE_CACHED would reject all users passing
      O_DIRECTORY with -EAGAIN, when in fact the intended test was to check
      for __O_TMPFILE.
