[PATCH v2] s390/virtio: mark headers as BSD licensed

[PATCH v2] s390/virtio: mark headers as BSD licensed

[Michael S. Tsirkin]

Virtio UAPI headers aren't just for UAPI, it's for guests/hypervisors as
well.  The s390 ones need to be BSD as well.

Fixes: e2be04c7f995 ("License cleanup: add SPDX license identifier to uapi header files with a license")

A word of warning - this is completely untested. I lost my s390
cross-build setup. Tested-by would be nice, otherwise
I will cross-build in the next couple of days and report here.

I'm not sure why you say your patch fixes the above commit. It just added a
tag that described reality, while you are _proposing_ to relicense the
header file.
That's a completely different story.

FWIW, this file will go away anyway. 
Looks like the following commit in the s390 feature branch 
https://git.kernel.org/pub/scm/linux/kernel/git/s390/linux.git/commit/drivers/s390/virtio/Makefile?h=features&id=7fb2b2d512448cf0e914c4647a1cf02b52263702
missed this file.


Regarding the virtio-ccw.h headers it is probably something that happened by accident.
Back then Rusty (as an IBMer) proposed to change all virtio headers to BSD licence.

ISTR that the relicensing already went through... is that not the case?
I thought this was just a fixup to align with reality?

The original kvm_virtio.h code was added in 2008

commit e976a2b997fc4ad70ccc53acfe62811c4aaec851
Author: Christian Borntraeger <borntraeger@de.ibm.com>
Date:   Tue Mar 25 18:47:46 2008 +0100

    s390: KVM guest: virtio device support, and kvm hypercalls




The BSD re-licencing happened in 2008

commit 674bfc23c585b34c42263d73fb51710d49762a23
Author: Rusty Russell <rusty@rustcorp.com.au>
Date:   Fri Jul 25 12:06:03 2008 -0500

    virtio: clarify that ABI is usable by any implementations
    
    We want others to implement and use virtio, so it makes sense to BSD
    license the non-__KERNEL__ parts of the headers to make this crystal
    clear.

and it seems that it missed arch/include/uapi/asm/kvm_virtio.h



arch/include/uapi/asm/virtio_ccw.h probably just copied what
kvm_virtio.h had in 2013.

So its somewhat fair to assume that both files should be BSD, but they are not
according to the licence statement.

Gregs SPDX change just changed the GPL text in the header files to a SPDX
statement. Now Michael wants to change this to BSD as it probably was intended
but not written down. Sigh.

Re: [PATCH v2] s390/virtio: mark headers as BSD licensed

[Christian Borntraeger]

So what about the following

- leave kvm_virtio.h unchanged and we will delete this file via the s390 tree

- change virtio_ccw.h to BSD license. The content of this file is really really trivial
and it boils down to 2 defines, that can be easily reconstructed by looking at the virtio spec.
Not even sure if something like this can be copyrighted.


For reference the content of this file minus comments is

- snip -
#define KVM_VIRTIO_CCW_RING_ALIGN 4096
#define KVM_S390_VIRTIO_CCW_NOTIFY 3
- snip -

GPLv2 and BSD dual licence might be better I guess.

Seems to be used by kvm_virtio.c - are you removing that too?

Yes. What prompted this was Greg's patch.

So I observed you are the original author and wrote most of the code in
kvm_virtio.h. I figured your ack will be enough.  I can get acks from
Alex, other changes seem to be mostly from you, other IBMers or trivial.

Let's do just in case.

So for ccw if both you and Cornelia ACK, we'll be fine I think.
No one else touched this code.

A patch that changes virtio_ccw.h to a dual gpl2/bsd licence is

Acked-by: Christian Borntraeger <borntraeger@de.ibm.com>

as it matches the original intent of the virtio header relicensing
from 2008 while at the same time covers the fact that the whole 
kernel is GPL2.
