#10572 obsolete readdir fail on a SharedFolder from linux guest and Win7 host vejmarie
Description

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.

#3186 obsolete Windows 7 (possibly other) task bar disappears while in Seamless mode Matt
Description

While using VirtualBox with a Windows 7 host there is an issue which causes the host taskbar to vanish while the guest operating system has focus. The bug is 100% reproducible. The problem only occurs when on the host machine windows background slideshow is enabled and at least two backgrounds are in the rotation list. Disabling background slideshow on the host remedies the problem.

Problem has been tested using a guest OS of Ubuntu 8.10 on two different host machines. Problem may exist in other versions of window's host.

#20648 duplicate Host Network not working veics
Description

The existing custom new host network adapter is not functioning. No network traffic passing through, you cannot ping the ip address of the local host network adapter, and you cannot communicate with any VM within that network. Re-creating the adapter and trying to set a custom ip address returns this error: Failed to save host network interface parameter. Callee RC: E_ACCESSDENIED (0x80070005).

Downgrading to VirtualBox 6.1.26 solved the issue. macOS 11.6 / Big Sur
