Description Bit Juggler 2024-02-28 09:06:06 UTC 
On my openSUSE Tumbleweed system (bare metal)

Operating System: openSUSE Tumbleweed 20240225
KDE Plasma Version: 5.27.10
KDE Frameworks Version: 5.115.0
Qt Version: 5.15.12
Kernel Version: 6.7.6-1-default (64-bit)
Graphics Platform: X11

I use virtualbox

# zypper se -si virtual*

The host shares a directory (/mnt/Lokal/VM_share) with the guest.

On the host system I have (in my home directory) a file

> ls -la *.jpg
-rw-r--r-- 1 A users 40749 Mar  3  2023 Opensuse_beer_label.jpg

when I copy this file to the shared directory

> cp -a Opensuse_beer_label.jpg /mnt/Lokal/VM_share/

everything looks fine (on the host)

> ls -la /mnt/Lokal/VM_share/
total 64
drwxr-xr-x 3 A   users  4096 Feb 27 09:51 .
drwxr-xr-x 7 root root   4096 Jan  3  2022 ..
-rw-r--r-- 1 A   users 40749 Mar  3  2023 Opensuse_beer_label.jpg
>

but on the guest system I see in the shared folder

> ls -la
total 64
drwxrwx--- 1 root vboxsf  4096 Jan  1  1970 .
dr-xr-xr-x 5 root root    4096 Feb 27 09:40 ..
-rwxrwx--- 1 root vboxsf 40749 Feb 27 09:44 Opensuse_beer_label.jpg

The timestamps in the share of the VM don’t make sense to me.

This happens to all files copied to the share.

Even when I copy files in the guest to the share their timestamps are changed (in the share) to the current date . However when I look at those files on the host they do have the correct date; i.e. the date of the original file in the guest.

On MS Windows 11 (bare metal) with virtualbox 7.0.14 and openSUSE Tumbleweed 20240225 as guest I see the same behaviour.

Kubuntu (as guest) does not show this behaviour although it uses VBoxGuestAdditions_7.0.14 as well.

I discussed this already here:

https://forums.opensuse.org/t/files-in-the-virtualbox-share-show-wrong-timestamp/172718

and a third user could very this behaviour in its setup as well.
Comment 1 Bit Juggler 2024-02-29 08:10:01 UTC 
Considering the fact that

host: MS Windows 10 (“pure” Oracle VirtualBox 7.0.14)
guest: Kubuntu 23.10 (“pure” Oracle VirtualBox GuestAdditions 7.0.14)

works fine I think there is some strong evidence that openSUSE Tumbleweed (as guest) might be the cause of the problem.

I have no idea how to debug this any further.

But if I can be of any assistance ...
Comment 2 Larry Finger 2024-03-07 12:37:58 UTC 
It appears that this is a kernel problem in an OBS build. If I build a kernel from the latest source using the factory configuration, it works. The "same" kernel loaded from a TW repository fails!
Comment 3 Bit Juggler 2024-03-07 16:07:50 UTC 
(In reply to Larry Finger from comment #2)
> If I build a kernel from the latest source ...

Is that the sources for kernel-default-6.8~rc7 ?
Comment 4 Larry Finger 2024-03-07 17:39:54 UTC 
It does not matter whether I use 6.8-rcX or 6.7.7. If I generate the kernel, it works. If OBS makes the kernel, it fails and I do not know why.
Comment 5 Larry Finger 2024-03-12 04:31:44 UTC 
No, I was working with 6.7.7. I just installed 6.8.0-1.ga551d7b-default and it shows the faulty behavior. All directories in the shared folder had a Dec. 1, 1969 date, and most data files show the current date. My locally generated copy also showed the same problem. I still have more work to do.
Comment 6 Zorrinski 2024-04-04 18:17:53 UTC 
I just updated to 
virtualbox-kmp-default 7.0.14_k6.8.2_1-7.2 with virtualbox-guest-tools 7.0.14-7.1 
from "openSUSE Tumbleweed Oss" repository 

and the issue is still there.

Are there any news in which version the issue is fixed?
Comment 7 Larry Finger 2024-04-04 18:49:47 UTC 
Unfortunately, this bug is not yet fixed. I am working on it now, but I still do not know where it happens. As Leap 15.4 and Fedora 39 are both OK as guests, my inclination is that something in the guest code is wrong.
Comment 8 Larry Finger 2024-04-24 16:39:37 UTC 
This bug is now fixed. The revised code has been submitted to Factory, and should be released within the next few days.
