guest additions do not build with 3.20 / 4.0 kernel

Error from Fedora Rawhide x86_64 guest with 3.20.0-0.rc0.git5.1.fc23.x86_64:

No time to look at this properly now, but some notes after a quick look. The BDI_* flags in question were only ever relevant for MMU-less systems and can probably go unconditionally from our driver. See also commit b4caecd4<1>. The structure member was removed in commit b83ae6d4<2>. Sadly no defines changed in that commit that we can test for.

[Frank Mehnert]

Should be fixed. Could you check for the latest 4.3 Additions in the test builds page?

[Andre Robatino]

VBoxGuestAdditions_4.3.23-98490.iso both allows building the guest additions for the 3.20 kernel, and allows graphical mode to work (I've been running the 3.19 kernel with the old guest additions, and graphical mode hadn't worked since a recent Xorg update). Thanks!

[Dom]

Can you point me to the 4.3.23 build for Linux amd64 please (Base + exte pack + iso)? The tesbuilds page is pointing to 4.3.21.

[Frank Mehnert]

Just use the "Guest Additions" build, that's the .iso image which does also support Linux guests.

[Dom]

Hi Frank, ok I have raised a new case because in my case it is the dkms build that fails.

https://www.virtualbox.org/ticket/13888

[Dom]

Hi Frank

Ok, saw that you set my case https://www.virtualbox.org/ticket/13888 as a dup of this one. Can you provide me with the amd64 package for Linux, guest iso, and ext-pack for 4.3.23 please?

Thanks, Dom

[Frank Mehnert]

Again: Please download the "Guest Additions" build from the testbuilds page as I already mentioned above!

[Dom]

Hi Frank,

I did download it. But my issue is that I can't even get to install the guest additions because the base installation of Virtual Box itself fails on the DKMS build during the installation of 4.3.22. So the steps I usually follow are:

1.Install debian package for VirtualBox

2. Install extension pack
3. Install guest additions.

At step 1, I get the following:

sudo apt-get install virtualbox-4.3 Reading package lists... Done Building dependency tree Reading state information... Done The following extra packages will be installed:

The following NEW packages will be installed:

[Frank Mehnert]

Oh, then this must be a different problem. Unfortunately the logfile from your ticket doesn't show any hint. Please have a look at

/var/lib/dkms/<your_module_name>/<your_module_version>/build/make.log

[Dom]

Ok, I added make.2.log

[Frank Mehnert]

Ok, it turns out that the host drivers code needs also an update, I missed that before, sorry. I've updated the Linux packages on the test builds page. Please let me know if they work for you. No need for a new ExtPack or another Additions.iso.

[Dom]

Hi Frank,

So the DMKS build and install work.Now what happens when I start my Windows guest (tried 4 times), the Guest machine and the Host machine totally freeze up and I have to manually power down. At each of the 4 attempts, the Windows Host froze ad different stages of the bootup process. Keep in mind I had to install ext-pack for 4.3.22. The reason being that it said my machine has saved state information that I was using USB 2.0.

[Dom]

Attached VBox.2.log

[Dom]

Hi Frank, do you need any other logs?

[Frank Mehnert]

I don't need logs. At the moment I think it could be a bug in the Linux kernel. I ran Linux 4.0-rc1 today as well and saw one host lookup which I never saw before using stable kernels. Therefore I recommend to use a stable Linux kernel (-rc1 could still contain bugs).

[Dom]

Thanks Frank, I will wait for a stable release then. When do you foresee 4.3.23 being released?

[Frank Mehnert]

The next release will be 4.3.24 (uneven build numbers denote development releases) and I cannot provide you an exact release day. But it's NOT in the range of many week, sorry for being unspecific.

[Dom]

Great, thanks Frank, you have been a great help :)

[Frank Mehnert]

VBox 4.3.24 contains the adaptions for Linux 4.0. However, I will keep this defect open until we can rule out any incompatibilities of VBox with Linux 4.0.

[Dom]

Thanks. I just saw 4.3.24 is out so I will give it a try.

[Valdis Kletnieks]

Heads up - am seeing a consistent crash with 4.0-rc1 and linux-next kernels with a strange traceback:

Yeah, no obvious reason for it to crash *there*....

It bisects down to this commit:

commit 1e02ce4cccdcb9688386e5b8d2c9fa4660b45389 Author: Andy Lutomirski <luto@…> Date: Fri Oct 24 15:58:08 2014 -0700

x86: Store a per-cpu shadow copy of CR4

Context switches and TLB flushes can change individual bits of CR4. CR4 reads take several cycles, so store a shadow copy of CR4 in a per-cpu variable.

I'm reasonably sure that the problem is that VirtualBox isn't onboard with the whole shadow copy thing, and hilarity and hijinks result when it twiddles CR4 and doesn't update the shadow copy, and they get out of sync. Some quick grepping suggests the problem is in vboxdrv/SUPDrv.c but I can't prove it.

Fortunately, we're still at -rc1, so there's still time to sort this out....

[Frank Mehnert]

Thank you for this valuable information! We will check this out.

[colorprint]

I have the same problem with 4.0-rc2 kernel - system crash when try to start VM. With 3.19 kernel it works fine.

[Frank Mehnert]

To say it explicit: Current VBox versions will NOT properly run on Linux 4.0, expect host crashes. The next 4.3.x maintenance release will contain a fix.

[Frank Mehnert]

See our test builds page for Linux test builds for 32-bit hosts and 64-bit hosts. These build contain the fix. It is NOT sufficient to update the host driver, the VBox code needs to be updated as well, so you would need to install the test build to confirm.

[colorprint]

Yes, the test build works fine with 4.0-rc2 kernel. Thanks!

[Valdis Kletnieks]

Verifying that test build 98815 works with 4.0.0-rc2-next-20150306 as well.

[Dom]

Cool, I just tried 4.0 rc3 and Vbox 4.3.25 and all is good now. Looking forward to GA releases on both ends.

[Valdis Kletnieks]

I've seen these two errors several times, not sure what triggers it. It's quite possible the second one is a result of wreckage left behind by the first error.

Running test build 98815, 64-bit Linux host....

Fix is part of VBox 4.3.26. For further issues on Linux 4.0, please open a different ticket.
