Cannot exec files on vboxsf on newer kernels

[jisakielkiel]

Reference: ​https://www.spinics.net/lists/reiserfs-devel/msg06411.html Patch was introduced on ​https://lkml.org/lkml/2020/8/17/174

Trying to execute a shell script from a shared mount fails on newer kernels (i.e. debian testing 5.10) with the error:

"kernel read not supported for file /test-exec"

Older kernels (i.e. 4.19 from stable) work.

This suggests vboxsf needs patches for the new APIs.

Also observed on:

• host Mac OSX Big Sur 11.3 on MacBook Pro (15-inch, 2018) with 32GB RAM
• VirtualBox 6.1.20 r143896 (Qt5.6.3)
• Vagrant 2.2.15 / vagrant-vbguest (0.29.0, global)

Ubuntu 21.04 guests are affected. Ubuntu 18.04 are not.

Please retry with VirtualBox 6.1.22 which was released today. Should be fixed.
