Cannot exec files on vboxsf on newer kernels

Reported by: jisakielkiel Owned by:
Component: guest additions Version: VirtualBox 6.1.18
Keywords: vboxsf exec Cc:
Guest type: Linux Host type: Mac OS X


Reference: Patch was introduced on

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.

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