Not really. The agreement does not cover any variant of System V.

For what it's worth, if I remember correctly, 4.3BSD was one of the major contributions to SVR4. I suspect that if it hadn't been, nobody would've bought it. bought the 4.xBSD for the reliability and usability. And yes, it would be nice if the entire SysVRx source trees were released under a suitable FOSS license; but I think the usefulness of such a gesture would be in stymieing any future "The SCO Group" shenanigans, and I don't know that such acts of self-preservation are quite the flavour of the month with modern software companies.

With SVR4, things became alot less distinct, and it was really only the linux camp that really kept beating the drum that they were still so different. It was more Sun with 4BSD based SunOS that contributed into SVR4 than 4.3BSD proper. At the time, that was some University somewhere, not what was current in the Unix world. There's both the STREAMS API (more properly XTI/TPI) and the STREAMS Kernel network processing paths. XTI/TPI have died by the wayside surplanted by the Sockets API, but the STREAMS kernel stuff is still very much part of Solaris. To me, it seemed like Sun never really gave all that it did for the streams kernel stuff back into SVR4, but alot of the networking code seemed to be an early draft of what Solaris did with it. Any SVR4 varients still ran with the streams networking kernel code. Yes SunOS was definately 4.xBSD and had lots of research and innovation I think. The big Sun Whitepaper book of research papers is pretty interesting reading. I didnt see AT&T driving new "business" aspects of any flavor of unix. They already had that perception going strong in the market. AT&T's goals were more of uniting the various paths of unix that were really already out. From the many BSD based systems with SysV influences (ie. SunOS, Ultrix), and the Sys III type systems, to the really strange one-off research type systems. All into one grand unified Unix to take over the market. Until the revolt for having AT&T be the overlord master overtook them and shattered it all again. Sun and AT&T were partners developing SVR4 to some extent. Some of Sun's tech went into SVR4 (based on their 4BSD based SunOS). To me, as an outsider, it seemed Sun kept alot of tech to itself and rolled it into Solaris. At the time, Sun's stated reason for creating Solaris was to move to multi-processor machines, and that the 4BSD based code had too many global-locks (something that FreeBSD had struggled with even relatively recently), and moving to the new architecture would be a lot easier for the future and would help them overcome those limitations. Of course, this migration probably took far far longer than they ever expected. But once Solaris actually became usable, it certainly did rock a lot more than SunOS on the hardware it was tweaked for. I didn't see Sun as not holding back on licensing SVR4. They seemed to get what they wanted out of the deal with AT&T, and created Solaris as their desired path out of the deficits they had with SunOS with the partners they had on hand.

Also as I understand it, SunOS was a BSD which had heaps of development and original ideas put into it (shared libraries I think is one example), but was discarded as a political decision because AT&T had managed to convince most corporate customers that BSD was merely a hack and SysV was the "real unix", so Sun decided to create Solaris instead by licensing SysV as a starting point, I may have things slightly backward so I would appreciate if anyone can confirm this? cheers, Nick

Yes, but I think the SunOS 4 shared library stuff was based on a.out, I remember looking at the ld.so source code and thinking how simple and elegant it all was, until those SysV people got their hands on it and created ELF ;) What SysV release introduced ELF though? cheers, Nick On Tue, Jul 12, 2011 at 9:22 PM, Tim Bradshaw <tfb(a)tfeb.org> wrote:
