virt: vbox: Add support for the new VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl Add support for the new VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl, this is necessary for automatic resizing of the guest resolution to match the VM-window size to work with the new VMSVGA virtual GPU which is now the new default in VirtualBox.

virt: vbox: Fix VBGL_IOCTL_VMMDEV_REQUEST_BIG and _LOG req numbers to match upstream Until this commit the mainline kernel version (this version) of the vboxguest module contained a bug where it defined VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG using _IOC(_IOC_READ | _IOC_WRITE, 'V', ...) instead of _IO(V, ...) as the out of tree VirtualBox upstream version does. Since the VirtualBox userspace bits are always built against VirtualBox upstream's headers, this means that so far the mainline kernel version of the vboxguest module has been failing these 2 ioctls with -ENOTTY. I guess that VBGL_IOCTL_VMMDEV_REQUEST_BIG is never used causing us to not hit that one and sofar the vboxguest driver has failed to actually log any log messages passed it through VBGL_IOCTL_LOG. This commit changes the VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG defines to match the out of tree VirtualBox upstream vboxguest version, while keeping compatibility with the old wrong request defines so as to not break the kernel ABI in case someone has been using the old request defines.

virt: vbox: Implement passing requestor info to the host for VirtualBox 6.0.x VirtualBox 6.0.x has a new feature where the guest kernel driver passes info about the origin of the request (e.g. userspace or kernelspace) to the hypervisor. If we do not pass this information then when running the 6.0.x userspace guest-additions tools on a 6.0.x host, some requests will get denied with a VERR_VERSION_MISMATCH error, breaking vboxservice.service and the mounting of shared folders marked to be auto-mounted. This commit implements passing the requestor info to the host, fixing this. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

virt: vbox: Add vbg_req_free() helper function This is a preparation patch for fixing issues on x86_64 virtual-machines with more then 4G of RAM, atm we pass __GFP_DMA32 to kmalloc, but kmalloc does not honor that, so we need to switch to get_pages, which means we will not be able to use kfree to free memory allocated with vbg_alloc_req. While at it also remove a comment on a vbg_alloc_req call which talks about Windows (inherited from the vbox upstream cross-platform code).

virt: Add vboxguest driver for Virtual Box Guest integration This commit adds a driver for the Virtual Box Guest PCI device used in Virtual Box virtual machines. Enabling this driver will add support for Virtual Box Guest integration features such as copy-and-paste, seamless mode and OpenGL pass-through. This driver also offers vboxguest IPC functionality which is needed for the vboxfs driver which offers folder sharing support.
