Detecting security problems – using static analysis to catch them early and less expensively

By Bill Graham

In my previous post I discussed the potential benefits in quality and costs that static analysis brings to software development. In addition to common coding errors, many of the bugs found by static analysis are potential security defects as well.  Buffer overflow, OS command injection, unrestricted string format and integer overflows are among the top 25 most dangerous security coding defects (according to the Common Weakness Enumeration (CWS) from the MITRE organization). These types of defects are common in C and C++ and are dangerous to correct operation in general but also pose significant security threats – often because the right exploit can lead to arbitrary code execution on the target. Once an attacker can execute code on your device, they can gain complete control, which might include reflashing the firmware, installing malware or rewriting the command and control software.

Using Static Analysis to Improve Product Quality, Earlier and Cheaper

By Bill Graham

Fixing bugs is expensive. Fixing bugs is more expensive the later you leave them, in fact, its been shown to cost a magnitude higher with each major phase of development. The famous defect cost chart from Capers Jones shows the cost of a bug going from $25 at the coding phase to $16,000 in development.  Not only that, but most of the bugs are introduced into the system at this stage yet very little of them are found. Logic says we should fix them earlier to save money.

Android Security – making sense of all the choices

By Chris Buerger

Last week’s public release of the Security Enhanced (SE) Android project and associated source code is hailed by many as an important foundational step to add a new set of options to create secure Android devices. While the recent release of the code base by the National Security Agency (NSA) is familiar territory for Android experts such as Wind River who have been designing and implementing comprehensive security layers to a wide spectrum of Android devices for a few years now, the portrayal of this development in the media as an all-encompassing security solution grossly oversimplifies the complex subject matter that Android security represents.

Simply speaking, compiling and flashing the SE Android code base on to your Nexus S will not make it completely 'secure.'

Wind River has been enabling Android devices for close to five years now. Based on that experience and over a decade of pioneering mobile Linux-based devices, four key security-related points stand out.

Wind River Linux: The Thrills Just Keep Coming

By Paul Anderson

When I joined Wind River over ten years ago, there were many in the company and in the embedded industry that saw open source software with extreme skepticism: too big, too slow, too risky, too expensive to maintain, and so forth. Over the years, the industry at large has figured out that open source software, particularly Linux, has an essential role in the embedded ecosystem, just as real time operating systems, software development tools, test frameworks, and many other things play a critical role in developing and deploying embedded device. But, the role of Linux embedded development represents something else, a fundamental change in the way people think and act as it relates to how software is developed, deployed and maintained in the embedded space. Linux is different.

Introducing Performance Studio

By Emeka Nwafor

What is Performance Studio? Is it:

1. Some kind of hair product

2. A new "clinic" for MLB players

3. Full name: : Wind River Linux Performance Studio for Intel® Architecture; a new add-on product for Wind River Linux that helps you get the most performance out of your embedded Linux device software running on Intel hardware 

If you correctly answered "3", give yourself a round of applause.

Our portfolio of development solutions have long addressed a broad set of embedded device development concerns in the areas of system definition, bring-up, software construction, integration & test, and maintaining and retro-fitting embedded device software and hardware. Now, with the introduction of Performance Studio, we not only have the broad development solutions portfolio but also further extend it with capabilities that enable us to go deeper into the platform and obtain the best performance out of embedded Linux software running on Intel® Core™, Xeon™, and Atom™ processors.

Adding Android to the Embedded Mix

By Dan Noal

Wind River just hosted a webinar titled, “Adding Android to the Embedded Mix" and saw a great attendee turnout. There were a broad spectrum of companies represented, not just the traditional smartphone and tablet manufacturers.  This is a clear indication of the interest to use in Android for devices in all market segments.  In fact, one of the most frequently asked questions is, what other embedded markets have you seen or do you see having an Android play? 

Wind River has been working with customers on Android for a wide range of applications and markets, and our efforts continue to expand.  We’ve worked on many projects including enterprise IP phones from the likes of Avaya and in-vehicle infotainment systems from Clarion.  

Increasingly, Android is finding its way into markets like point-of-sale, fit-to-purpose industrial style tablets, and other device categories where a strongly supported application framework and active application ecosystem are important elements of platform choice.

Secure Mobility Message Resonates at MILCOM 2011

By Chip Downing

MILCOM 2011 last week in Baltimore, MD was not only educational, but it was a watershed event.   Last year, it was a “coming out” party for custom Android devices; this year however, was the year where many companies are now using COTS hardware and software to their fullest extent, along the entire supply chain, from core to edge and user devices.   I believe this COTS adoption is driven by two powerful forces – the exploding capabilities of commercial tablet devices, and global military budget pressures.

The vastly increasing power and capability of commercially available mobile communications devices is simply amazing. Just a few years ago, almost everything in this military communications space was purpose built, and most commercial products were simply inadequate to address the rugged and complex system demands of military communications systems.   As seen at MILCOM 2011, this has officially changed -- COTS end-to-end communications domains rule.

So if all of these MILCOM vendors are not making customized hardware and software, what are they doing?   Wind River had over 500 people visit its booth at MILCOM this year, and most of the discussions I had with both suppliers and end users at the show were about increasing device security and leveraging high volume COTS components in demanding deployment scenarios.

Cloud to Service Endpoints – The Missing Link

By Paul Anderson

I remember as a kid I was fascinated with phones. The idea that you could pick up the phone, dial it, and talk to someone on the other end was pretty neat. And… at the time, a phone was an elegantly designed electro-mechanical work of art, and it was fun to take them apart to try and figure out how they worked. I could understand how the phone itself worked, but as a kid, what happened after those two wires headed off to the pole was somewhat of a mystery to me. Eventually I came to understand the massive infrastructure that allowed reliable telephone service into the home to be possible. Hats off to Alexander Graham Bell, the inventor of the telephone.

When you think of a basic phone, it seems like such a simple thing. It can receive, it can transmit, and it can provide bidirectional signaling. Receiving and transmitting is obviously important, and it took a while for folks to figure out how to do both simultaneously without a bunch of extra wires and things. Signaling is equally important. The user of the device needs to know when someone is trying to contact them, and to be able to establish contact with someone else out on the network. A phone is actually a very clever thing, particularly when one thinks of what people did with what they had at the time, particularly in a world before the transistor.

But, what is a phone really? It is a service gateway. In its most simple form, it provides telephone service. That service then allows connectivity to other services, like the ability to call the plumber when your sink gets clogged, or order a pizza. Quite amazing!

Linux in Medical Devices

By Ken Herold

Linux is the operating system of choice for a wide range of medical devices, from vital sign monitors to hospital bedside “infotainment” systems to complex imaging and scanning equipment. Yet not all Linux is alike. Because patients’ lives may be in the balance, software used in medical devices must meet stringent regulatory guidelines to assure that it will perform as promised, and the provider must be able to pass audits of its development methodologies. Trying to cobble together solutions from pure Linux without commercial support puts the burdens of testing, validation, documentation and compliance on the device manufacturers and their developers – an onerous, time consuming and complex process that can turn “free” Linux into a very costly proposition.

There are, of course, commercial vendors of Linux who provide value-added, stabilized versions of the open source software, along with board support packages. Service, support and documentation levels, however, vary widely among them.  Some chip vendors provide software solely to drive processor sales and with many vendors, the relationship ends with the sale.

Unmanned Systems: More Reports of Security Vulnerabilities

By Joe Wlad

By now, you’ve likely heard the latest report of security holes in unmanned ground control systems. This time, a key-logging virus has been found on one or more hard drives at the Nevada operations center for the Predator and Reaper unmanned vehicles. While the investigation is ongoing and impact of the virus is determined, the real concern is just how vulnerable are these systems and what might happen next? This is not the first time security gaps have been uncovered in unmanned vehicles. In 2009, Iraqi insurgents were able to intercept unencrypted video feeds from operational Predator UAVs using inexpensive software downloaded from the Internet.

People in the public and private sector are expressing deep concern over how things like this can happen and to how address these problems. As for the “how we got here” question, it’s relatively simple to answer. Essentially, the unmanned air vehicle has been a victim of its own success. Many of these programs, Global Hawk, Predator and others were never designed to be deployed in operational environments. In fact, the DoD in many cases, sought to build these vehicles as prototypes or proof-of-concepts. When the programs were awarded, the diligent contractors for these vehicles used the best of commercial technology to demonstrate the capabilities. The hope was that successful demonstrations would lead to production contracts where the systems could be designed to meet specific security and safety requirements.

Linux, Common Criteria and OS Protection Profiles

By Paul Parkinson

In 2011, computer and network security news stories, which were previously the preserve of specialist journals and blogs, have become commonplace in the mainstream media. There are now many different types of threat, which are sometimes categorised into hacktivist, e-crime and most recently, advanced persistent threats (APT). Whilst some of these attacks have exploited zero day vulnerabilities, many of these attacks have simply taken advantage of the fact that systems have not been configured securely for their deployment environment.

To use an easy–to-understand analogy, consider a wireless router. This device will generally be shipped from the factory in the most flexible, open communication configuration, which will have many or all of the security options disabled. This will be fine if the wireless router is intended to be used as a free public Wi-Fi access point (e.g., cyber cafe), but not for a private business or home office if you want to prevent drive-by wireless hacks).  In these cases, wireless encryption such as WPA2 will need to be enabled for the router and clients, and access may even need to be restricted to specific clients via MAC addresses, etc.

Feeling the need for speed and making it happen

By Mark Guinther

“I feel the need…The need for speed!!”  Quoting old movies is where my similarities to Tom Cruise end, but it is a relevant line for today’s networking equipment.  Faster applications is one of the last steps in getting faster results to subscribers, resulting in happy subscribers which means happy service providers, happy service providers mean happy equipment providers, and… well, you get the point: Everybody is happier when their network runs faster. However, it’s getting tougher given the ever-increasing flood of data on today’s networks.    

Bigger, faster pipes are a start, but you can have the best infrastructure plumbing in the world and still have poor performance if your system and applications are a bottleneck.

Platform Wars

By Dan Noal

In recent weeks, we’ve seen two seismic shifts in the mobile and tablet markets. First, Google announced its intent to acquire Motorola Mobility and a few days later, HP announced that it would discontinue producing webOS-based phones and the TouchPad. 

Google’s move to buy a hardware manufacturer has long been speculated in the media.  Motorola Mobility had previously been reported as a possible target, so Google’s move isn’t entirely surprising. However, after nearly 3 years since the public launch of Android, the question is why now?  Consider the comments of Android industry partners (e.g. Samsung, HTC, Verizon) mentioning the need to protect the Android ecosystem from IP lawsuits that threaten Android’s growth.  Now add the fact that Motorola Mobility has grown a significant patent portfolio in the mobile space over the past decade. 

Still, it is interesting to wonder about the long-term vision.

Are Penguins Ready to Fly?

By Nithya Ruff

This year, Vancouver, British Columbia was the site for LinuxCon North America 2011, where Linux celebrated its 20^th anniversary.  Vancouver is normally known for its rainy and gray weather, but the Linux gods must have been shining on the Linux celebrations because the weather was spectacular!  In the same year that Wind River celebrates its 30 anniversary, it got me thinking about if this was a forecast of things to come.  

Turning 20 is a coming of age milestone and that can truly be said of Linux.   I see a well-established ecosystem of upstream open source projects, successful commercial companies based on open source and an increasing number of industries that are adopting Linux.   Business models are maturing and there is a good understanding of the value that commercial vendors bring to creating adoption and making it safe to use Linux.  There seems to increasingly be a process for working across and within groups.  Look at what the Linux Foundation does. It provides an umbrella organization for collaboration projects like the kernel, Meego and Yocto to organize and move things forward and advocate for the Linux community very effectively.  It also provides a physical venue for people to gather and meet face to face and create vision and directions.

Fish Finders, Embedded Linux and Graphics

By Paul Anderson 

Here I am up at rustic cabin in Northern Wisconsin enjoying some time off the grid. I feel like Ralph Waldo Emerson getting in touch with nature, and exploring Transcendentalism, except for one minor detail: I have a wireless connection. Emerson was quoted as saying “Nature hates calculators,” and I’m not sure what he would think about the billions of connected devices scattered across the landscape. Not to worry, I’ll be back unplugged soon enough and enjoying some quality time in the “digital free zone.”

I tried my hand at some fishing this week on the little lake we are on. Even though I’m a gadget person in general, I am a very low tech fisherman. With the help of my brother in law, my kids and I just fished the old fashioned way, with a pole, hook, bobber, and worm. It didn’t take long to find the fish, or for the fish to find us. However, there are plenty of high tech anglers out there that use everything from advanced weather forecast maps, fish finders, and even underwater cameras. I find all that technology interferes with the peace of mind that I am looking for when doing things like fishing, but perhaps that is because I am fully immersed in technology as a career.

Modern high end fish finders, GPS units, and other electronics equipment used in the outdoors have become much more sophisticated. The users of deeply embedded devices have come to expect a graphical user interface, low power consumption, and reliability. A similar trend can be found across a spectrum of deeply embedded devices, including industrial control panels, medical equipment, military applications, and of course, consumer equipment.

Android software quality: it's all in a single number

By Chris Buerger

Picture this: you are responsible for ensuring that the quality of the Android device you are about to ship will hold up in front of your customers. You are responsible that it will meet the often elusive 'commercial quality' goal. And it doesn't matter whether the Android software is being released as an initial software load on a new class of device or as a maintenance release for a device that is already in market. Also, ignore for a moment whether you sourced the Android software from your hardware Original Device Manufacturer (ODM) as part of a package deal or whether it represents significant investment into internal engineering budget.

The basic question to answer is simply: 'Is this software ready to be released?'. Or casting the net wider, will the software be good enough to stay below the return targets for the device? Will it be so good to act as a differentiator vs. your competitors and therefore help to meet your customer acquisition goals? And, if the software goes out to devices already in market, will it keep its users as engaged and satisfied with your brand as the prior device?

Google I/O and MeeGo Developer Conference – A Tale of Two Events

By Chris Buerger

First off, let me say that it is not fair to directly compare the two conferences to draw a conclusion about the comparative future of Android and MeeGo. Both software stacks are at a different place in their respective life cycles, and important maturity indicators such as overall ecosystem support (silicon providers, device manufacturers, application developer community etc…) as well as software quality/complexity are simply at a different stage for each technology.

However, who is interested in fairness? There is a perception in the marketplace that Android and MeeGo are competitive technologies in a proliferation war that includes other heavyweights such as Apple, Microsoft, Samsung and HP. If industry analysts put all of these software stacks on a single Mobile OS market share chart, they’ve got to be competitive, right?

Not quite. One important reason Android got to where it is today is that its first mass-market device, the HTC G1, sold millions of units across the globe, thus delivering a very tangible proof point to rally a worldwide ecosystem to participate in the development of Android. MeeGo’s proliferation, partly because of the rather wide device scope the software stack is attempting to cover, is following a different path.

Embedded is cool (and getting even cooler)

By Paul Anderson

When people ask me what I do, I never know how to answer the question. Most people state their occupation. But, does that define what we do? I usually respond with something cheeky like “metabolize,” or “provide for those around me” or “go running or fly airplanes any chance I get.” But, usually people want to know what you do for a living. I usually get stumped when they ask that particular question.

I asked my youngest child what he thought I did for a living. He said “play with computers all day,” which is not entirely inaccurate. I asked my oldest, and he said “fly airplanes” (again, I do fly a lot of airplanes, but unfortunately I spend most of my time as a passenger rather than a pilot). My pets would say my entire existence is dedicated to providing them food and entertainment (obviously they have figured something out). My wife would say that I type on the computer, talk on the phone, go to meetings, and spend way too much time in airplanes and at hotels. Although accurate, it doesn’t get at the core of what I do.

When I try to explain to people what I do in any detail, after a minute or so I see their eyes glaze over. I have taken to just saying “I’m in the software business.” I can usually get away with that, but sometime people actually want to know more.

Getting Started with OpenSAF

By Glenn Seiler

Usage of OpenSAF is growing exponentially. The number of companies I hear from that are evaluating or considering using OpenSAF grows every month. A common trend that I see more and more often is that someone in an R&D capacity or someone charged with creating a prototype downloads OpenSAF from opensaf.org and begins working with it, to acquaint them with the technology.  For example, if you are a Wind River Linux user, you can download a pristine version of OpenSAF software directly from the Wind River Developers Network that has been pre-validated and packaged to build with Wind River’s Linux Distribution Assembly Tool (LDAT).  The version of OpenSAF you can download from Wind River Developer Network is exactly the same as the current version of OpenSAF at devel.opensaf.org, except it has been put into a ‘layer’ that is recognized and used by Wind River’s build environment. This can save significant time and effort for companies that want to do a quick analysis or build of OpenSAF.

The most common method for getting support or help for OpenSAF projects is by utilizing “community support.” The Wind River Developer Network is a great place to look for answers or to post a question. This is where members of Wind River’s OpenSAF and Linux engineering community can help. In addition, the OpenSAF project has many helpful documents and mailing lists that can provide help.  There are many mailing lists that you should consider subscribing to, including a developers mailing list that is used by many of the actual developers contributing code to the OpenSAF project.

Is Linux Secure?

By Paul Anderson

It’s the wrong question, really. Are my financial and medical records secure? What about all that information stored in the cloud? What about my desktop computer or cell phone? What about the power grid and other infrastructure? Should I be worried?

The answer to all those questions is “It depends on what you mean by ‘secure.’” One may need to consider: What is the definition security? Or what is an acceptable level of risk at that level of security?

Wind River Turns 30: Looking Back and Moving Forward

By Tomas Evensen 

2011 marks Wind River’s 30th anniversary. The big 3-0…it’s a major landmark moment in anyone’s book. This year, we’ll be taking time to honor this milestone with a retrospective of Wind River’s history and also a series of employee stories.  In my many years with the company, Wind River always impressed on me the concept of  being bigger than just a single product or technology. There is an underlying spirit within our teams that constantly reaches for more, for some greater innovation. While many customers know Wind River for the VxWorks real-time operating system, it was always part of the vision to provide more value. In the early days, this entailed providing a TCP/IP stack and GDB for debugging. Later, additional value came from strong IDE support through Tornado and Workbench. Lately, it has been by providing a choice of operating systems, real-time or open source/Linux. 

A standout example that exemplified the vision of providing a more complete solution was when we embarked on creating a truly embedded hypervisor. In 2004, it had already become clear to us that virtualization would play an important role in embedded designs at some point in the future. In early 2005, Paul Borman who worked for me in the CTO Office created a very impressive prototype, called eCPU, that ran VxWorks and Linux on a single CPU and we learned a lot from that effort. When Johan Fornaeus came on board in 2006 through an acquisition (he was co-founder of Interpeak and before that, one of the co-designers of the Enea/OSE operating system), I had him leading a small nimble task force team to develop a hypervisor really suited for the embedded space. I felt we made a real breakthrough. This was not a repackaged operating system pretending to be something it was not designed for, but instead a truly unique approach to virtualization and separation. Over the next couple years, this small team created a scalable product with an extremely tight footprint, incredible performance, while at the same time being full featured for the common architectures such as Intel, Power, ARM and MIPS.

Back in those days, it was not clear to us when and how important multi-OS systems would be in the future, but today it is hard to imagine how to deal with these new complex systems without a hypervisor for embedded virtualization. Looking at my team’s achievement now, I still marvel at how the Wind River Hypervisor brings together multi-core and our various operating systems. Why choose between operating systems with different characteristics when you can mix them in one system? Throw in a networking stack optimized for multi-core and tools that can debug and find performance bottlenecks and you get a very capable foundation on which our customers can innovate.

By constantly looking to the future, Wind River continues to evolve and further build on its expertise. The ongoing push to innovate may have created interesting and complex challenges along the way. However, it has also resulted in celebrations and breakthroughs, and it’s undoubtedly a big reason why so many of us continue to stay on the ride. 

 

Fun with VxWorks MILS 2.1

By Paul Parkinson

It's been awhile since my previous blog, as I have been rather preoccupied with responding to a number of RFPs. However, I’ve managed to find some time to work on some demos for VxWorks MILS 2.1, which has been fun.

VxWorks MILS 2.1 introduced support for Wind River Linux as a Guest OS (VxWorks Guest OS and High Assurance Environment (HAE) having been supported in the earlier VxWorks MILS 2.0 release). I wanted to get some more hands-on experience of using Wind River Linux as a Guest OS (GOS) running on the VxWorks MILS 2.1 Separation Kernel (SK). So, I started with a version of theBlaster Blastee demo which had been modified by one of my colleagues in Engineering to use a Linux GOS partition for the Blaster. (Blaster Blastee is a well-known Wind River demo which provides a nice flexible framework for blasting TCP or UDP packets between nodes, testing network connectivity and performance).

 I thought it would be an interesting exercise to extend the demo to also use Linux in a second partition as the Blastee (receiver), to demonstrate the scalability and determinism of the MILS SK with multiple Linux virtual boards (VB).

Will embedded Linux development ever defragment?

By Paul Anderson

We have seen the power of open source and open standards transform much of the enterprise space, particularly in the server market. Before the success of open source in server space, there were really only two choices: Run an operating system and applications developed and maintained by a hardware manufacturer, or choose one of only a few commercial operating systems and applications that spanned different manufacturers.  Hardware manufacturers optimized each operating system to best suit the hardware they sold, creating a lack of compatibility between hardware manufacturers. Alternatively, commercial enterprise operating systems typically were not optimized for each hardware platform, and as a result, did not perform well. Given these scenarios, a system architect, integrator, or developer, often had to make hard choices and compromises.

With the advent of open source operating systems and applications, the software landscape changed dramatically. After a slow start, there was a bloom of available operating systems and applications available. There was little standardization or compatibility between the different operating system, distribution, and application variants. It was nice to have a choice, but all of these options also created fragmentation. With time, open standards within the enterprise space developed, from carrier grade standards (CGL), to application environment standards (LSB), to standardized application stacks (LAMP). For a variety of reasons, there has not been a single distribution or package standard, but things are now similar enough that system architects, integrators, and developers have a fairly standardized environment and a rich ecosystem of hardware and software from which to choose.

Now consider the embedded community – the world of deeply embedded development has evolved in a much different manner.

The Dawn of a Paradigm Shift in Embedded Device Software Security

By Marc Brown

The number of connected embedded and mobile devices is increasing exponentially, predicted to be in excess of 50 billion by 2020.  The lion’s share of this growth is expected to come from traditional market segments where there is an increasing push to transform sensing equipment to more autonomous embedded control, real-time telemetry, and proactive diagnostics. We all know website hacking is nothing new, but just imagine having your public water utility meter, your automobile safety functions, our public transportation traffic sensors, or even the national power grid being hacked by organized criminals or nation states.  This tsunami of connectivity and more intelligent control is creating a huge increase in security vulnerabilities that can impact financial profitability, public services and safety, and national defense. 

Many of today’s most advanced embedded control systems are based on a collection of standalone components – embedded operating systems, virtualization technologies, communication stacks, middleware, and application code.  These standalone products, and the companies that create them, lack the integrated security support required in today’s highly connected world, offering overall solutions that are only as safe as the weakest link. 

McAfee and Wind River have formed a strategic partnership to develop and support comprehensive, purpose-built security solutions specifically designed for these next-gen embedded devices.

Making the Case for MeeGo 2.0

By Chris Buerger

As an owner of the original Maemo-based N770, today is a sad day. Earlier, Nokia announced it would make Windows Phone 7 Nokia’s primary mobile platform, not MeeGo. This puts the brakes on what many considered a bold corporate initiative to bring Linux to a new class of Nokia mobile devices. Well before the iPad, well before the undoubtedly innovative yet largely undifferentiated avalanche of Android based devices, there was a dream, a vision to create unique Linux software for a new class of Nokia devices.

There are plenty of opinions that this announcement marks the end of MeeGo. Personally, I do not subscribe to that view. MeeGo, and the open source projects that are part of it, has a place in open source mobile Linux, and in many cases will continue to evolve and thrive.

Embedded Virtualization Opens New Possibilities

By Mark Hermeling

One of the things that stands out in many customer visits that I do is that embedded virtualization often enables possibilities that the customer never thought possible. This of course is a good thing, it may enable them to put a new product to market that the customer had never thought of. In a few cases I have seen customers use virtualization to shift their business models from shipping custom hardware to shipping software only using COTS boards. Virtualization in this case is used to provide the customization that they formerly needed hardware for.

I went on a customer call earlier this year to a customer that was looking to go to multi-core. The customer was building a networking product and was using VxWorks on a single core Intel processor and wanted the additional processing power that a dual or quad-core could provide. They wanted to go to multi-core and came to Wind River to see what their options were.

Virtualization on Handsets or not?

By Mark Hermeling

Here is an interesting article, continuing a discussion thats has been going on for a long time on mobile virtualization. It argues the case that a single mobile phone can run multiple operating systems using virtualization. A bit of googling will show that this is indeed already the case. However, there is a big caveat typically that you do not see exposed. 

Mobile phones have two big constraints: processing power and battery power. Typically one operating systems is the 'phone operating system' and the other OS is more general purpose. With 'phone OS' I mean that the OS has to handle a lot of the time critical tasks, sometimes even to the level of passing data off to/from the signal processing side for communication with the antenna and the wireless network.

The signal processing side is very time sensitive and hence it is important that the time constraints are met and data is delivered/picked up on the right time. This makes it that typically the virtualization layer will have to be aware of this and it makes the solution not a general virtualization solution, but a highly device customized solution.

Low-cost Android phones: Feature phones an endangered species?

By Chris Buerger

There is no doubt that there will always be a set of consumers that only want their mobile phone to be, well, a phone. Voice calling is likely to remain the ‘killer app’ for the majority of consumers for a long time to come, and there will remain a sizeable section of the mobile phone market that will cater to this demand.

However, the market change to smartphones is undeniable, even in the last bastions of feature phone-centered markets such as Japan and South Korea, Android-based smartphones are rapidly winning market share at the high end of the device spectrum. Now, a second wave of the Android smartphone revolution is happening in many countries, and I am excited to say that Wind River mobile software solutions for Android are right in the thick of things, helping to drive this new wave of devices.

Cambridge, Cows and CELF

By Paul Anderson

I'm currently in Cambridge, UK and having a great time at the Consumer Electronics Linux Forum (CELF) Embedded Linux Conference. I enjoyed a great ride on the London Underground and then the train to Cambridge. It's always fun to watch the folks come and go at the various stops and countryside scroll by. It's fun to observe what happens on a typical day. In spite of a bit of rain, Cambridge is a vibrant town - many students, folks on bikes, nice places to eat, and interesting architecture and history. Thanks to some disciplined co-workers, I've gotten up each day at 6AM for a morning run along the River Cam. While running through the dark along the river, we suddenly encountered some large black and white lumps that we soon realized were cows resting in a pasture. They looked on with mild amusement as we ran through the pasture, wondering what might be chasing us. It's always fun to be in the city one minute, and in the country the next!

The CELF Embedded Linux Conference events were fantastic. It was a small conference of 260 attendees, but those who attended are among the best and brightest open source developers and leaders focused on embedded applications.
