[Qemu-devel] Clearing slirp/ license

[Qemu-devel] Clearing slirp/ license

[Marc-André Lureau]

Hi,

As we are trying to move slirp/ in a standalone project, which
eventually could be installed as a shared library, we need to clear
the license.

slirp is supposed to be 3-Clause BSD license (according to
https://git.qemu.org/?p=qemu.git;a=commit;h=2f5f89963186d42a7ded253bc6cf5b32abb45cec)
but it seems to be effectively a 2-Clause BSD (the third clause is not
in COPYRIGHT)

However, there are two units that are GPL-2:

- dhcpv6.c, dhcpv6.h:
  The code was contributed by Thomas Huth <thuth@redhat.com>

$ git shortlog -nes slirp/dhcpv6.{c,h}
     6  Marc-André Lureau <marcandre.lureau@redhat.com>
     1  Philippe Mathieu-Daudé <f4bug@amsat.org>
     1  Thomas Huth <thuth@redhat.com>
     1  Yuval Shaia <yuval.shaia@oracle.com>

- ncsi.c, ncsi-pkt.h:
  The code was contributed by Cédric Le Goater <clg@kaod.org>

$ git shortlog -nes slirp/ncsi.c slirp/ncsi-pkt.h
     5  Marc-André Lureau <marcandre.lureau@redhat.com>
     4  Cédric Le Goater <clg@kaod.org>

Could you reply that you have no objection in relicensing those files
are 3-Clause BSD?

After "[Qemu-devel] [PATCH 0/7] slirp: make it a standalone project",
the vmstate subset that I adapted would also need to be relicensed.
There are more contributors here, I am not sure how it should be
handled. Any idea?

thanks

Ok, for the records: I'm fine if you change the license of dhcpv6.[ch]
to either 3-Clause BSD or 2-Clause BSD.

Fine for me. You can change the license of slirp/ncsi.c and 
slirp/ncsi-pkt.hto a 3-Clause BSD.

Thanks,

Thanks Thomas & Cedric.

Since this mail was sent, slirp/src/vmstate.c was added, based on qemu
implementation, which is attributed to Juan Quintela/

Juan, Could you reply that you have no objection in relicensing the
vmstate files as 3-Clause BSD?

thanks!

I noticed that ncsi-pkt.h has "Copyright Gavin Shan, IBM Corporation 2016"

I suppose Gavin should also give his agreement to relicense the file.


Gavin, could you reply that you have no objection in relicensing
ncsi-pkt.h as 3-Clause BSD?
