I did refer to authors in history, in case that was unclear. I was thinking of how much code we rewrote for TCG, qdev, etc. In the end it'll depend on which files are affected, and I don't have a list - hard to grep due to varying formulations and line breaks.

Authors in history (unlike authors in git blame, but you cannot trust that) almost never disappear, no matter how much you rewrite. Even dyngen->TCG kept a lot of the target-* code unchanged.

Including binutils code is just a bad idea. I know noone wants to hear that but it's unfortunately true. The FSF does copyright assignment which means it's easy for them to relicense. Since we don't do copyright assignment, it's much, much harder for us to relicense. We'd waste huge amounts of man hours trying to chase binutils license. We need to stick with the v2 version of binutils and perhaps work toward an alternative in the future. Relicensing is just not practical.

The disassembler is also used with -d in_asm or -d out_asm to write qemu.log. I expect that a pipe to an external disassembler would slow down execution with -d significantly.

How difficult would it be to add tracing to tcg-target.c such that you could get out_asm that way? At least with i386, there's just a few instruction forms so it should just be a matter of a few trace points with a table of opcode names. Likewise, we could add tracing to translate.c to achieve the same affect as in_asm. Tracing's probably a far better approach for debugging as you would be able to do some very interesting things with SystemTap and such a mechanism.

We are a userspace package, though, and kernel headers are not copyrightable. Unlike perf we do not define APIs, we're just a consumer even for KVM (by design!). And when something we pull in is not headers (no example comes to mind), the copyright holder is quite often one of two well-known employers.

It's not something that any one person can really change. It would require a very large effort. To give you an idea of the scope, I ran the following command: $ grep GPL *.c hw/*.c | grep -v 'or later' | cut -f1 -d: | sort -u | while read i; do echo $i; git log --format=" %an <%ae>" $i | sort -u; done Here's the results. All of these people would have to explicitly SoB a relicense of that specific file to include a "v2 or later" clause. In some cases, there's code from Thiemo which cannot be relicensed due to his untimely passing. aio.c Alexander Graf <alex@csgraf.de> aliguori <aliguori@c046a42c-6fe2-441c-8c8c-71466251a162> Andrea Arcangeli <aarcange@redhat.com> Anthony Liguori <aliguori@us.ibm.com> Avi Kivity <avi@redhat.com> Blue Swirl <blauwirbel@gmail.com> Kevin Wolf <kwolf@redhat.com> Nolan <nolan@sigbus.net> blockdev.c Alexander Graf <agraf@suse.de> Anthony Liguori <aliguori@us.ibm.com> Blue Swirl <blauwirbel@gmail.com> Christoph Hellwig <hch@lst.de> Eduardo Habkost <ehabkost@redhat.com> Gerd Hoffmann <kraxel@redhat.com> Jes Sorensen <Jes.Sorensen@redhat.com> Kevin Wolf <kwolf@redhat.com> Luiz Capitulino <lcapitulino@redhat.com> Marcelo Tosatti <mtosatti@redhat.com> Markus Armbruster <armbru@redhat.com> Ryan Harper <ryanh@us.ibm.com> Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> block-migration.c Alex Williamson <alex.williamson@redhat.com> Anthony Liguori <aliguori@us.ibm.com> Avishay Traeger <AVISHAY@il.ibm.com> Blue Swirl <blauwirbel@gmail.com> Jan Kiszka <jan.kiszka@siemens.com> Jan Kiszka <jan.kiszka@web.de> Liran Schour <lirans@il.ibm.com> lirans@il.ibm.com <lirans@il.ibm.com> malc <av1474@comtv.ru> Marcelo Tosatti <mtosatti@redhat.com> Markus Armbruster <armbru@redhat.com> Pierre Riteau <Pierre.Riteau@irisa.fr> Shahar Havivi <shaharh@redhat.com> Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Yoshiaki Tamura <tamura.yoshiaki@lab.ntt.co.jp> buffered_file.c aliguori <aliguori@c046a42c-6fe2-441c-8c8c-71466251a162> Anthony Liguori <aliguori@us.ibm.com> Avi Kivity <avi@redhat.com> blueswir1 <blueswir1@c046a42c-6fe2-441c-8c8c-71466251a162> Blue Swirl <blauwirbel@gmail.com> Glauber Costa <glommer@redhat.com> lirans@il.ibm.com <lirans@il.ibm.com> malc <av1474@comtv.ru> Marcelo Tosatti <mtosatti@redhat.com> Michael S.

Yes, also just to get it written somewhere: the list of copyright holders is merely indicative. Anyway, unfortunately this is, I think, a lost battle. For linux-user there's too much Linux kernel code. It would still be nice to not introduce more GPLv2-only code, but don't hold your breath...

However, it may not be available on all systems, and I don't think cross-disassemblers are installed by default. Perhaps we can make it an optional component loaded with dlopen()?

TCG can have a debug mode that makes it GPLv3 (using the binutils code). You wouldn't be able to consume this debug mode with linux-user.

Nah, the simplest thing to do is to really implement a binary format to store (or pipe) in_asm and out_asm traces. Then the trace dumper could use all the binutils code it wants to, and would be the only thing requiring a v3 license. in_asm/out_asm traces are so huge that this thing does have some actual benefit if somebody wants to write it. That said, it is still nice if we can get people to agree on relicensing what they own, if only to help sharing code with other GPL programs. With the obvious exception of MIPS and linux-user, it does not seem impossible, though indeed hard, and it is also a good occasion to clean up files without a license.

This would work for linux-user since the there is no monitor, so linux-user could be left as GPLv2. For the system emulators, it would be a small improvement for in_asm or out_asm logs, but the builtin monitor disassembly command would have to fork and exec this external tool. But if that's the only unsolved case, perhaps that feature could be made conditional to libopcodes.so instead. > That said, it is still nice if we can get people to agree on relicensing > what they own, if only to help sharing code with other GPL programs.

Sure, but the Author shouldn't Signed-off-by on a copyright change if there are other copyright owners that also need to approve. SoB is stating that you are entitled to submit the patch which in case of copyright change means you own the copyright or got permission from the copyright owner. That's why we should have all authors include a SoB. It provides the paper trail of anyone who may have touched the file.

SoB is stating that > you are entitled to submit the patch which in case of copyright change means > you own the copyright or got permission from the copyright owner. Yes, you need "permission from the copyright owner", but that only amounts to "permission from the copyright owner to submit under this license", not "permission to relicense the code as you feel like later". (cf clause (b) of the "Developer's Certificate of Origin".) That document also says later that you can modify the change as you pass it up providing you add your signed-off-by too, so the whole set of people who signed-off-by some patch are potentially copyright-authors, which was my original point. -- PMM ^ permalink raw reply [flat|nested] 63+ messages in thread
