guest additions do not build with 4.10 kernel -> fixed in 5.1.x and later releases after 19 Dec 2016

[Andre Robatino]

Got an error message while attempting to install guest additions in a Fedora Rawhide guest for the 4.10.0-0.rc0.git2.1.fc26.x86_64 kernel.

vboxadd.sh: failed: Look at /var/log/vboxadd-install.log to find out what went wrong.

This should fix it. Will commit later. See this kernel commit:

The fix should be available in 5.1 and higher Guest Additions builds<1> as of revision 112422.

[Andre Robatino]

Thanks. I want to test the 112428 GA, but unfortunately neither of my installed 4.10 kernels are bootable. I can boot into a 4.9 kernel. Is it possible to boot into one kernel and install the Guest Additions for another? (This used to be possible via a "dkms install" command, when the GA used DKMS.)

[Andre Robatino]

Installed the 112428 Guest additions, then installed the newest 4.10 kernel. The GA build still fails. Attaching vboxadd-install.log.

Fix is part of VBox 5.1.12.

[Andre Robatino]

Still broken with 5.1.12, after installing the new GA, restarting the guest, and installing a new 4.10 kernel. Attaching vboxadd-install.log.

Also please update the Version to "VirtualBox 5.1.12", since I don't have permission. Thanks.

Dear

The compile error refers to kernel.h from the linux kernel. The following changes to kernel.h introduced the compile error.

​https://github.com/torvalds/linux/commit/4d98ead183a2be77bfea425d5243e32629eaaeb1

It seems the vars 'true' and 'false' in the taint_flag struct are overwritten by the macro defined in vboxdrv/include/iprt/types.h lines 264 - 270

Not so well picked var names in kernel.h I would assume...

[Frank Mehnert]

Replying to Lieven Tytgat:

Exactly. I hope that ​this patch gets merged into the vanilla kernel before 4.10 is released.

[Larry998]

That patch changing those badly chosen names has been accepted, but it is not yet merged into mainline. Be aware that that change is not sufficient for VB to build under kernel 4.10-rc2 and later as register_cpu_notifier() and unregister_cpu_notifier() are removed. Code must now use the hotplug state machine to register cpu on- and off-line events. This change is not trivial, and I have not yet come up with a fix. Larry

[Larry998]

Crude hack to allow VB to build on kernel 4.10-rc2 and later

[Larry998]

The attachment posted above will allow a successful build once my patch to fix the "true" and "false" redefinition problem has been applied.

[Lieven Tytgat]

Linux 4.10-rc5 will rename the true and false chars in c_true and c_false, fixing this issue. Commit: ​https://github.com/torvalds/linux/commit/5eb7c0d04f04a667c049fe090a95494a8de2955c

I think we have new compile error with Linux 4.10-rc5.git1.1.fc26.x86_64 I made this fix: ​https://github.com/rpmfusion/VirtualBox-kmod/blob/master/kernel-4.10.0-0.rc5.lnkops.patch

seems to me trivial when we read ​https://patchwork.kernel.org/patch/9327855/

[Frank Mehnert]

I think the correct patch is in r65409 and this change is part of the most recent 5.1 Guest Additions which can be found here (5.1 Guest Additions .iso image).

Confirming that guest additions build for kernel-4.10.0-0.rc7.git0.1.fc26.x86_64 when using VB 5.1.14 and VBoxGuestAdditions_5.1.15-113104.iso.

[Andre Robatino]

Filed https://www.virtualbox.org/ticket/16506 for guest additions not building with the 4.11 kernel (while using the latest VBoxGuestAdditions_5.1.15-113518.iso guest additions).

[Frank Mehnert]

Fixed in VBox 5.1.16.
