readdir fail on a SharedFolder from linux guest and Win7 host

[vejmarie]

Hi,

I am running VB 4.1.8 on a Windows 7 system (latest available patch running from Microsoft). The linux guest is running ubuntu server with kernel v 3.0.0-19. I am mount a vbox shared folder called Multimedia which contain videos and images. The folder is properly mounted and I can read file through ls and other shell command.

I wanted to use Mediatomb DLNA application on top of this directory, but the application fail to read properly directory content. A simple readdir in the home directory where the mount point is created is not reporting the mount directory as a dirent, and the application did not detect it at all.

The file permission is also strange, as I can't change them. drwxrwxrwx 1 www-data www-data 8192 2012-05-16 22:55 Multimedia is the result of a ls on the mount point.

drwxr-xr-x 8 www-data www-data 4096 2012-05-16 22:55 . drwxrwxrwx 1 www-data www-data 8192 2012-05-16 22:55 Multimedia drwxr-xr-x 5 www-data www-data 4096 2012-03-23 19:48 . drwxr-xr-x 2 www-data www-data 4096 2012-03-21 18:17 Videos drwxrwx--- 4 www-data www-data 4096 2012-03-13 10:42 ..

is the full ls -lta. And the result of the readdir loop following an opendir and closedir is reporting: . .. Videos which are standard linux directories.

The mount command is

mount -t vboxsf -o uid=33,gid=33 $shared_folder /usr/share/wordpress/wp-content/uploads/host_$magic/$shared_folder

from a standard bash script.

When I am running the ls -lt command I got a green backlight into my shell like if bash was reporting the directory as a special one.

From Mediatomb source code

dir = opendir(path.c_str());

if (! dir) {

throw _Exception(_("could not list directory ") +

path + " : " + strerror(errno));

}

while ((dent = readdir(dir)) != NULL) {

char *name = dent->d_name; log_debug("Looking for directory:%s\n",dent->d_name);

The Looking for directory display call never display the Multimedia directory.
