      Orangefs: de-uglify orangefs_devreq_writev, and devorangefs-req.c in general · 97f10027
      Mike Marshall authored
      AV dislikes many parts of orangefs_devreq_writev. Besides making
      orangefs_devreq_writev more easily readable and better commented,
      this patch makes an effort to address some of the problems:
      
       > The 5th is quietly ignored unless trailer_size is positive and
       > status is zero. If trailer_size > 0 && status == 0, you verify that
       > the length of the 5th segment is no more than trailer_size and copy
       > it to vmalloc'ed buffer. Without bothering to zero the rest of that
       > buffer out.
      
      It was just wrong to allow a 5th segment that is not exactly equal to
      trailer_size. Now that that's fixed, there's nothing to zero out in
      the vmalloced buffer - it is exactly the right size to hold the
      5th segment.
      
       > Another API bogosity: when the 5th segment is present, successful writev()
       > returns the sum of sizes of the first 4.
      
      Added size of 5th segment to writev return...
      
       > if concatenation of the first 4 segments is longer than
       > 16 + sizeof(struct pvfs2_downcall_s) by no more than sizeof(long) => whine
       > and proceed with garbage.
      
      If 4th segment isn't exactly sizeof(struct pvfs2_downcall_s), whine and fail.
      
       > if the 32bit value 4 bytes into op->downcall is zero and 64bit
       > value following it is non-zero, the latter is interpreted as the size of
       > trailer data.
      
      The latter is what userspace claimed was the length of the trailer data.
      The kernel module now compares it to the trailer iovec's iov_len as a
      sanity check.
      
       > if there's no trailer, the 5th segment (if present) is completely ignored.
      
      Whine and fail if there should be no trailer, yet a 5th segment is present.
      
       > if vmalloc fails, act as if status (32bit at offset 5 into
       > op->downcall) had been -ENOMEM and don't look at the 5th segment at all.
      
      whine and fail with -ENOMEM.
