vboxfs EPROTO error during file read

Reported by: snblitz Owned by:

Cc: Guest type: Linux
Host type: Linux


I recently attemped to use vboxsf/vboxfs to make an Ubuntu 8.04 host filesystem available in an Ubuntu 8.04 guest instance.

All worked fine initially. A relatively simple application in the guest reads and writes files into a folder in the shared directory.

Every once in a while the read() system call returns EPROTO. However, simply repeating the open/read/close works.

It was failing about 1% of the time.

I mounted the filesystem via NFS rather than vboxfs and the operations work 100% 24 hours per day for days on end.

The operations also work days on end if the files are read/written to the filesystem inside the guest.

I was unable to find anything in the log files at the time of the failed read calls.
