'du -b' bug in fileutils-4.1

[David Eisner]

Hi.  I think there's a bug in the 'du' utility in fileutils-4.1.

du -b is supposed to report the size of the file in bytes.
The observed behavior is that du -b reports the size rounded
up to the nearest multiple of 1024, however:

    venice[ /venice/cradle ]% ls -l file.dat
    -rw-rw-r--   1 cradle   calce        417 Feb 19 18:29 file.dat
    venice[ /venice/cradle ]% fileutils-4.1/bin/du -b file.dat
    1024    file.dat

The expected behavior is that du -b report '417' as the size.

The problem seems to have been introduced in fileutils-4.0:

    venice[ /venice/cradle ]% ls -l file.dat
    -rw-rw-r--   1 cradle   calce        417 Feb 19 18:29 file.dat
    venice[ /venice/cradle ]% fileutils-3.16/bin/du -b file.dat
    417     file.dat
    venice[ /venice/cradle ]% fileutils-4.0/bin/du -b file.dat
    1024    file.dat
    venice[ /venice/cradle ]% fileutils-4.1/bin/du -b file.dat
    1024    file.dat


The problem is in the count_entry() function in du.c:

    507
    508   size = ST_NBLOCKS (stat_buf);
    509   tot_size += size;
    510

but in v3.16, we have:

    514   if (output_size == size_bytes)
    515     size = stat_buf.st_size;
    516   else
    517     size = ST_NBLOCKS (stat_buf);
    518
    519   tot_size += size;

Thanks.
