Microsoft contributes to Linux
Microsoft announced that it is to contribute device driver code to the Linux kernel under the GPLv2. Prompting us to publish a CAOS Theory Q&A. Answering one questioning we failed to ask, ZDnet reported that Microsoft’s Linux contributions should find their way into the 2.6.32 release.
Acquia raises $8m
Mass High Tech reported Acquia has picked up an $8m second funding round from existing investors. The funding was later confirmed by the company.

Microsoft has announced that it is to contribute code to the Linux kernel development effort under the GNU General Public License (GPL) v2. What on earth does it all mean? Here’s our take on the situation. With thanks to Jay Lyman for his contribution to the following:
Q. This is a joke, right?
A. Not at all, although if any announcement is better suited to the image above, we can’t think of one. Microsoft has announced that it is going to contribute code to Linux under the GPLv2.
Q. What code is Microsoft contributing?
A. Microsoft is offering 20,000 lines of its own device drivers to the Linux kernel that will enable Linux to run as a guest on its Hyper-V virtualization technology. Specifically, the contributed loadable kernel modules enable Linux to run in ‘enlightened mode’, giving it efficiencies equivalent to a Windows virtual machine running on Hyper-V.
Q. Why is Microsoft doing this?
A. Red Hat and Novell’s Linux distributions already support enlightened mode, thanks to the development work done by both in partnership with Microsoft. One benefit for Microsoft of contributing to the kernel is that it reduces duplication of effort and the cost of supporting multiple, unique implementations of Linux. Once the code has been accepted into the kernel, Microsoft will use the kernel tree code as the basis for future virtualization integration development.
It also means that community Linux distributions will be able to use the code, which opens up more opportunities for Microsoft in the hosting market, where adoption of community Linux distributions such as Ubuntu, Debian and CentOS is significant. It also therefore slightly strengthens the challenge those community operating systems can make to Red Hat and Novell, which are more direct commercial challengers to Windows.
Make no mistake about it, Microsoft’s contribution is driven by its own interests. While it must serve and respond to enterprise customers that continue to drive the use of multiple operating systems and mixed environments, Microsoft also benefits by differentiating its Hyper-V virtualization technology from virtualization leader VMware. We believe Microsoft sees an opportunity to make virtualization with Windows more Linux-friendly than VMware.
Q. What’s in it for Linux?
A. The interoperability benefits previously reserved for ‘approved’ Microsoft partners will now be available licensed under the GPLv2, and available for all Linux distributions – commercial or community – without the need for a formal partnership.
The contribution of device drivers to the Linux kernel as been a sticking point for the Linux development community in the past as developers have struggled to encourage vendors to contribute driver code to the kernel. Microsoft is therefore setting something of a precedent and could encourage other vendors that have been reticent to contribute their drivers to do so.
The seal of approval Microsoft has given to the GPLv2 is also not to be overlooked. If Microsoft can find a way to contribute to Linux projects, many other organisations may also be encouraged to do so.
Q. I guess Linux is no longer “a cancer” then?
A. Exactly. Back in 2001 Steve Ballmer told the Chicago Sun-Times* “Linux is a cancer that attaches itself in an intellectual property sense to everything it touches. That’s the way that the license works.”
Reviewing the statement in the context of today’s announcement demonstrates how much progress Microsoft has made in the intervening years to understand open source licenses. Contribution to Linux, or to any other project under the GPL, would have been unthinkable at the time, and is still barely believable today. The announcement is likely to challenge perceptions of Microsoft’s strategy when it comes to open source, Linux and the most popular open source license.
*The original article is no longer available online. Plenty of references are still available, however.
Q. What does this say about Microsoft’s overall strategy towards open source?
A. The contribution is a significant sign that Microsoft is now prepared to participate with open source projects on their own terms by using the chosen license of that project and making contributions directly to the chosen development forge of that project. Microsoft continues to use its own CodePlex project hosting site for code releases, but if an existing open source project uses SourceForge then Microsoft has acknowledged that the best way to engage with that community is on SourceForge. Don’t expect this to be the last contribution Microsoft does under the GPL.
Microsoft is now becoming more proactive in how it engages with open source under a strategy it describes as ‘Open Edge’ (which we have previously mentioned here and here. Whereas Open Core is used by commercial open source vendors to offer proprietary extensions to open source code, Open Edge is Microsoft’s strategy to encourage open source development and application deployment on top of its suite of commercial software: Windows, Office, Exchange, Sharepoint, SQL Server etc.
The Open Edge strategy is rooted in attempting to ensure Microsoft’s commercial products continue to be relevant to the ecosystem of developers and partners that the company has attracted to its software platform. It is also a continuation of the realization that if customers and developers are going to use open source software, Microsoft is more likely to retain those customers if it helps them use open source on Windows et al.
For more details on Microsoft’s strategy towards open source, its partnerships with open source vendors, and its contributions to open source projects, see The 451 Group’s formal report on the contribution to Linux (the report will shortly be available via this link ).
Q. How is the contribution to the Linux kernel being handled?
A. The contribution is being made via an alliance with the Linux Kernel Driver Project and its maintainer, Greg Kroah-Hartman, who will steward the contribution into the Linux kernel code base. (Greg has a post up about it here).
Q. What are the intellectual property issues?
A. The copyright for the code will remain with Microsoft, with the contributor credit going to its engineering lead, Hank Janssen, group program manager at Microsoft’s Open Source Technology Center.
Q. And patents?
A. If we were putting money on the most likely conspiracy theory to emerge in response to this news it would be that this is a Trojan horse and Microsoft is contributing code to Linux that it will later claim patent rights over. Whether that is even theoretically possible depends on your understanding of the GPLv2.
The GPLv2 contains an implicit patent promise that some would say makes a Trojan horse impossible. However, the FSF obviously thought it necessary to introduce a more explicit patent promise with the GPLv3 to remove any doubt.
Ultimately this is a question for a lawyer, or an eloquence of lawyers (yes it is ironic, apparently). In the meantime, it is our understanding that Microsoft’s understanding is that contributing code using the GPLv2 includes a promise not to charge a royalty for, or assert any patents covering, the code being contributed.
Q. What about Microsoft’s prior claim that Linux infringes its patents?
A. Microsoft really dropped the ball on its communication of the suggestion that free software infringes over 200 of its patents, and tensions with free and open source software advocates are likely to continue to be tested by Linux-related patent agreements, such as the one struck with Melco Holdings last week, which have driven scepticism and mistrust of Microsoft among some key open source supporters.
Absent the company giving up on software patents altogether, we believe that in order to convince those FOSS advocates that it is serious about co-existence, Microsoft needs to find a way to publicly communicate details about those 200+ patents in such a way that is not seen as a threat and would enable open source developers to license, work around, or challenge them. We also believe that the company is aware of this, although finding a solution to the problem will not be easy. But then neither was contributing code to Linux under the GPLv2.
UPDATE – It has subsequently become clear that there were two important questions that were not answered by our Q&A. Those have been covered by an addendum – UPDATE.

Sun shareholders approve Oracle deal
As expected, Sun’s shareholders approved the proposed acquisition by Oracle, reportedly in the absence of Scott McNealy and Jonathan Schwartz. Meanwhile people continue to be obsessed with Oracle killing things. If its not OpenSolaris then its Unbreakable Linux.
The un/importance of the GPL
Matt Asay speculated on Apache and the future of open-source licensing, in doing so referring to the GPL as “an alternative way to release proprietary software”. Needless to say that put the cat amongst the pigeons, with Glyn Moody stepping forward to explain why the GNU GPL still matters and Savio Rodrigues contemplating why open source vendors will continue to select the GPL. Meanwhile Benjamin Black reported on the failings of the GPL in the cloud era.
While we’re on the subject of open source licenses, Andrew Binstock argued that the OSI needs to consider licenses with defined limitations, while we pondered the theory of natural selection as it applies to license proliferation in the context of our recent long-form report, CAOS 12 – The Myth of Open Source License Proliferation.
Incidentally, on Tuesday, July 21 at 1:00pm EDT we will be hosting a webinar to discuss some of the findings from the report. Register here.
