Linking GPL and openssl is not allowed due to the advertising clause in BSD. The socat people realized that and say: the advertising clause in BSD? I suppose you meant the advertising clause in openssl license? license --- socat is distributed under the terms of the GNU GPL; except for install-sh, which is copyright MIT, with its own license; In addition, as a special exception, the copyright holder gives permission to link the code of this program with any version of the OpenSSL library which is distributed under a license identical to that listed in the included COPYING.OpenSSL file, and distribute linked combinations including the two.

My understanding is: the author of socat allows us to link socat to the lib openssl? Koen, I'm really not good at the license stuff at all. Could you please explain the situation in more details? What need we do if we want to add the socat recipe into poky? It has already been in OE for a long period of time.

Linking GPL and openssl is not allowed due to the advertising clause in BSD. The socat people realized that and say: the advertising clause in BSD? I suppose you meant the advertising clause in openssl license? Yes, indeed license --- socat is distributed under the terms of the GNU GPL; except for install-sh, which is copyright MIT, with its own license; In addition, as a special exception, the copyright holder gives permission to link the code of this program with any version of the OpenSSL library which is distributed under a license identical to that listed in the included COPYING.OpenSSL file, and distribute linked combinations including the two.

My understanding is: the author of socat allows us to link socat to the lib openssl? Correct. I don't know what happens when you include socat in a GPL product, but that's for other people to worry about :) Koen, I'm really not good at the license stuff at all. Could you please explain the situation in more details? From what I've understood the advertising clause is consired a restriction by the GPL and hence incompatible. Since openssl is so widespread and gnutls so buggy the exception was invented to allow openssl to link with gpl software. What need we do if we want to add the socat recipe into poky? It has already been in OE for a long period of time. Some googling suggests that 'GPL-2.0+-with-OpenSSL-exception' is SPDX compatible, so we could put that in LICENSE. regards, Koen signature.asc Description: Message signed with OpenPGP using GPGMail ___ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
