      configfs: Fix race between configfs_readdir() and configfs_d_iput() · 24307aa1
      Joel Becker 提交于
      configfs_readdir() will use the existing inode numbers of inodes in the
      dcache, but it makes them up for attribute files that aren't currently
      instantiated.  There is a race where a closing attribute file can be
      tearing down at the same time as configfs_readdir() is trying to get its
      inode number.
      
      We want to get the inode number of open attribute files, because they
      should match while instantiated.  We can't lock down the transition
      where dentry->d_inode is set to NULL, so we just check for NULL there.
      We can, however, ensure that an inode we find isn't iput() in
      configfs_d_iput() until after we've accessed it.

      configfs: Don't try to d_delete() negative dentries. · df7f9967
      Joel Becker 提交于
      When configfs is faking mkdir() on its subsystem or default group
      objects, it starts by adding a negative dentry.  It then tries to
      instantiate the group.  If that should fail, it must clean up after
      itself.
      
      I was using d_delete() here, but configfs_attach_group() promises to
      return an empty dentry on error.  d_delete() explodes with the entry
      dentry.  Let's try d_drop() instead.  The unhashing is what we want for
      our dentry.

      cifs: fix cifsConvertToUCS() for the mapchars case · 11379b5e
      Jeff Layton 提交于
      As Metze pointed out, commit 84cdf74e broke mapchars option:
      
          Commit "cifs: fix unaligned accesses in cifsConvertToUCS"
          (84cdf74e) does multiple steps
          in just one commit (moving the function and changing it without
          testing).
      
          put_unaligned_le16(temp, &target[j]); is never called for any
          codepoint the goes via the 'default' switch statement. As a result
          we put just zero (or maybe uninitialized) bytes into the target
          buffer.
      
      His proposed patch looks correct, but doesn't apply to the current head
      of the tree. This patch should also fix it.

      cifs: add fallback in is_path_accessible for old servers · 221d1d79
      Jeff Layton 提交于
      The is_path_accessible check uses a QPathInfo call, which isn't
      supported by ancient win9x era servers. Fall back to an older
      SMBQueryInfo call if it fails with the magic error codes.
