      cifs: don't dereference smb_file_target before null check · 8c6c9bed
      Colin Ian King authored
      There is a null check on dst_file->private data which suggests
      it can be potentially null. However, before this check, pointer
      smb_file_target is derived from dst_file->private and dereferenced
      in the call to tlink_tcon, hence there is a potential null pointer
      deference.
      
      Fix this by assigning smb_file_target and target_tcon after the
      null pointer sanity checks.
      
      Detected by CoverityScan, CID#1475302 ("Dereference before null check")

      CIFS: Add direct I/O functions to file_operations · be4eb688
      Long Li authored
      With direct read/write functions implemented, add them to file_operations.
      
      Dircet I/O is used under two conditions:
      1. When mounting with "cache=none", CIFS uses direct I/O for all user file
      data transfer.
      2. When opening a file with O_DIRECT, CIFS uses direct I/O for all data
      transfer on this file.

      CIFS: Add support for direct I/O write · 8c5f9c1a
      Long Li authored
      With direct I/O write, user supplied buffers are pinned to the memory and data
      are transferred directly from user buffers to the transport layer.
      
      Change in v3: add support for kernel AIO
      
      Change in v4:
      Refactor common write code to __cifs_writev for direct and non-direct I/O.
      Retry on direct I/O failure.
