           Summary: abnormal behavior readdir on fat16
           Product: eCos
           Version: unknown
          Platform: All
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: minor
          Priority: low
         Component: FAT filesystem
        AssignedTo: unassigned@bugs.ecos.sourceware.org
        ReportedBy: arteminus@yandex.ru
                CC: ecos-bugs@ecos.sourceware.org
             Class: Advice Request


I heve code:
...
  ret = mount("/dev/synthdisk0/" , "/", "fatfs");
  DIR *dirp;
  dirp = opendir( "/dir3/" );
  while (true) {
    struct dirent *entry = readdir( dirp );
    if( entry == NULL ) break;
    debug_printf("%s",entry->d_name);
  }
...
And have directory(filesystem fat16):
/mnt/loop/dir3# ls
dir1  dir2  file1  file2  mmm  text

Why I get list1 instead list2?
list1:
.
..
Af
FILE1
Af
FILE2
Ad
DIR1
Ad
DIR2
At
TEXT
Am
MMM

list2:
.
..
FILE1
FILE2
DIR1
DIR2
TEXT
MMM

I think this is a mistake(may be at work with long file names) and should
correct in
/packages/fs/fat/current/src/fatfs_supp.c in function
static int
read_next_raw_dentry(fatfs_disk_t        *disk,
                     fatfs_data_pos_t    *pos,
                     fat_raw_dir_entry_t *dentry)
{
...
+++if(dentry->attr == 16 /*dir*/ && dentry->attr == 32 /*file*/)
...
}
