[SRU] Please sync vbox modules from virtualbox 6.0.6 on next kernel update

[Gianfranco Costamagna]

[SRU Justification]

Impact: The virtualbox package was updated in disco just prior to release, with numerous bug fixes. It is standard practice during development to sync our in-kernel source with the latest version of the virtualbox-guest-dkms package, however this upload was done so late in the release that there was not time to update the source in our kernel tree.

Fix: Re-sync the vbox guest dkms drivers from virtualbox 6.0.6-dfsg-1.

Regression Potential: This is a sync from the dkms package in the disco-release pocket, thus the code has presumably been tested against the Ubuntu Disco kernel. However, this is a very large pile of changes, and contains more than just bug fixes, so regressions are possible.

Test Case: Boot a kernel with the updated driver in virtualbox and confirm that the guest drier functionality works as expected.

---

* the changes are already in disco (vbox-guest-dkms), and they are fixes for the kernel 5.0.
They might seem a lot of changes, but they are needed, and probably some of them are even CVE fixes...

As said, vbox 6.0.6 includes lots of fixes for host/guest kernel modules, and they should be syncd when possible.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

yes, the kernel contains the new kernel modules for vbox, thanks!
