Symbolic links with `..` result in `protocol error` on vboxsf + 5.0.4

Reported by: scoates Owned by:
Component: shared folders Version: VirtualBox 5.0.4
Keywords: Cc: sean@…
Guest type: Linux Host type: Mac OS X


When creating a symlink that contains .., we're seeing "protocol error" messages. For this example /vagrant is none on /vagrant type vboxsf (rw,nodev,relatime).

cd /vagrant ; mkdir test ; cd test ; ln -s ../Vagrantfile .
ln: failed to create symbolic link `./Vagrantfile': Protocol error

This also happens when linking .. and not into the root. It does not happen when linking .. outside of the vboxsf system. This happens for us on 5.0.4r102546 but not on 5.0.0r101573.

It may be related to the following:

Note: if the symlink is made on the host FS (and not created on the VM), it seems to behave normally/correctly.

Host for our tests is Mac OS X 10.10, guest is Debian Jessie.

Also worth noting: I can successfully create symlinks on the vboxsf filesystem that do not contain ..

Just wanted to add my voice to this. Took me hours to figure out the problem because it occurred by trying to run npm install, not just making symlinks

FWIW, mine happened when doing an automated-at-provisioning git checkout (which happened to contain ../ symlinks).

Replying to sunlover:

I had the same problem.

My setup:

  • VirtualBox Version 5.0.4
  • OS X 10.10.5
  • docker-machine version 0.4.1
  • Vagrant 1.7.4

Symlinks are working again with your posted 5.0.5 testversion. Looks good to me!

Confirmed. Works for me on 5.0.5r102721. Thanks! Looking forward to 5.0.5-actual

Works for me. Macbook Pro Mid 14, 10.10.5

Any timeline when 5.0.5 will be shipped? This bug is affecting us, we can't run npm install (because it uses relative symbolic links).
