[Qemu-devel] [PULL 2/8] slirp: relicense GPL files to BSD-3

[Marc-André Lureau]

In order to make slirp a standalone project, the project must have a
clear license, and be compatible with the GPL or LGPL.

Since commit 2f5f89963186d42a7ded253bc6cf5b32abb45cec ("Remove the
advertising clause from the slirp license"), slirp is BSD-3. But new
files have been added under slirp/ with QEMU GPL license since then.

The copyright holders have been asked to relicense files to BSD-3 and
gave their permission:

- slirp/dhcpv6.{c,h}

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

Thanks,

C.

That was done. I had our legal team approve the change of license.

Thanks,

No objection. Please go ahead with the relicensing.

Cheers,

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

No problem at all on my side.
