Grsecurity and VirtualBox

Hi guys. smile

I have compiled a custom kernel with the latest grsecurity patch (for linux-4.2.3). Everything works fine except that I'm unable to run a virtual machine using VirtualBox. As soon as I try to start the VM, the system hangs completely. In the kernel configuration I have selected the CONFIG_GRKERNSEC_CONFIG_VIRT_HOST and CONFIG_GRKERNSEC_CONFIG_VIRT_VIRTUALBOX options. I also compiled VirtualBox modules with dkms.

This is what I find in the journal:

Is this just a bug or is there something else I should do to make it work? I'd like at least to understand what's going on. Any help is appreciated. smile

Re: Grsecurity and VirtualBox

When starting "virtualbox" from terminal:

libkmod: kmod_module_new_from_loaded: could not open /proc/modules: Permission denied
Error: could not get list of modules: Permission denied
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (4.2.3.201510072230-1-grsec) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /sbin/rcvboxdrv setup

         You will not be able to start VMs until this problem is fixed.

Is this just a bug or is there something else I should do to make it work? I'd like at least to understand what's going on. Any help is appreciated. smile

I think this problem because of this: https://bugs.archlinux.org/task/46633

With linux-grsec-4.2.3 i have one more problem.
After mount and unmount USB physically - all system freezes!!!
Only restart button help (((
I tested it with 2 different systems: one with intel, other with amd processors.

PS: now i downgraded my kernel to "sudo pacman -U linux-grsec-4.1.7.201509201149-1-x86_64.pkg.tar.xz"
and system doesn't freeze after unmounting USB FLASH.
Virtualbox i will test later...

Re: Grsecurity and VirtualBox

As an update, I have compiled the kernel with the option PAX_MEMORY_UDEREF disabled. Though this hasn't solved the problem (I'm still unable to run a VM), now I simply get an error message ("A critical error has occurred while running the virtual machine and the machine execution has been stopped"), but the system doesn't freeze anymore.

EDIT
Here's the VBox.log: https://gist.github.com/ab83ec8dea4409306150

Re: Grsecurity and VirtualBox

I have installed QEMU/KVM + libvirt.
This config working with Grsecurity+PAX without any issues smile

I'm using WinXP, Windows 7 on QEMU/KVM.

PS: goodbye virtualbox... smile
Grsecurity support advises to use KVM too.

I will try it. smile

Still, I'd like to be able to run VMs using VirtualBox with grsecurity, since I'm used to it and it works quite well for me with a vanilla kernel. sad

Re: Grsecurity and VirtualBox

Fuxino, did you eventually manage to get VirtualBox guest to work in grsecurity-host system?

Have you seen this article and this thread and tried the suggestions?

Nope, and eventually I switched to qemu/kvm, since it worked without much trouble. smile

Thanks for the suggestion, if I decide to try again with VirtualBox I'll try those suggestions, and maybe someone else will find them useful anyway smile
