To: linux-cifs@vger.kernel.org Content-Type: text/plain; charset="UTF-8" Dear all, This message is a follow up on a message I initially wrote about a year ago. I have the following setup: Windows 11 machine running in VirtualBox, hosted on Ubuntu 22.04. The Windows machine uses MS OneDrive to connect to our corporate OneDrive for SharePoint. Inside the OneDrive directory structure, I have created a Windows share. Let's call it "mydata". Whenever the Windows 11 machine is running, on my Ubuntu host, I then run `sudo mount.cifs //192.168.56.2/mydata /mnt/mydata -o username=marc,uid=1000,gid=1000`. This will then mount the Windows share and I can work with the files on Ubuntu. The reason for my message last year was that since my Ubuntu host machine upgraded to kernel 6.8.0-40-generic, I was no longer able to mount the "mydata" Windows share. Thanks to the great work of the community this was addressed and in version 6.8.0-60-generic I was able to mount the share again. However, I noticed that any PDF file I tried to open from this share would fail. Evince reports "Unable to open document PDF document is damaged". This then caused me to again revert back to kernel 6.5.0-45-generic. Today, I found some time for some testing with a newer kernel version to see if the issue is still present. I used mainline-gtk to install kernel version 6.15.7-061507-generic. This kernel portrays the same problem when trying to open a PDF file. Opening and editing text files, spreadsheets and images via the share is no problem. Hopefully someone can have a look into this situation. Thank you. Regards, /|/|arc.
